CROSS-REFERENCE TO RELATED APPLICATIONS
This patent application is a continuation-in-part of U.S. Utility Patent Application Serial No.
09/809,357, filed in the U.S. Patent and Trademark Office on March 15, 2001 by Ferguson et al., the entire contents of which being hereby incorporated by reference herein.
BACKGROUND
1. Technical Field The present disclosure generally relates to safety shields for medical needles, and more particularly, to safety shields that protect a needle point of a medical needle.
2. Description of the Related Art Problems associated with inadvertent needle sticks are well known in the art of blood sampling, percutaneous medication injection and other medical procedures involving use of medical needles. Significant attention has been focused on needle stick problems due to the contemporary sensitivity of exposure to AIDS, Hepatitis and other serious blood-borne pathogen exposures.
Procedures for removing a needle from a patient commonly require a technician to use one hand to place pressure at the wound site where the needle is being withdrawn, while removing the needle device with the other hand. It is also common practice for an attending technician to give higher priority to care for the wound than is given to disposal of a needle. In the case of typical needle devices without safety shields, such priority either requires the convenience of an available sharps container within reach or another means for safe disposal without leaving the patient's side. Providing adequate care while following safety procedures is often compounded by the patient's physical condition and mental state, such as in burn units and psychiatric wards. Under such conditions, it is difficult to properly dispose of a used needle while caring for a patient.
The widespread knowledge and history associated with needle care and disposal problems have resulted in numerous devices for preventing accidental needle sticks.
Problems of current safety devices include difficulty of use and high cost due to their complexity and number of parts.
Other known devices employ sheaths that are spring activated, telescoping, pivoting, etc.
These devices, however, may disadvantageously misfire or be cumbersome to activate. Further drawbacks of current devices include high manufacturing cost due to complexity and the number of parts. Thus, these type prior art devices may not adequately and reliably shield medical needle apparatus to prevent hazardous exposure.
Consequently, there remains a need to provide a more satisfactory solution for needle safety devices by overcoming the disadvantages and drawbacks of the prior art.
Therefore, it would be desirable to provide a more adequate and reliable medical needle shield apparatus which employs a safety shield slidably movable along a medical needle to prevent hazardous exposure to a needle tip. Such a needle shield apparatus should be easily and reliably movable to shield a needle tip of a needle cannula.
SUMMARY
Accordingly, the present disclosure addresses a need for a medical needle shield apparatus which effectively and inexpensively protects a tip of a medical needle after use. The present disclosure resolves related disadvantages and drawbacks experienced in the art. More specifically, the apparatus and method of this invention constitute an important advance in the art of safety needle devices.
In one particular embodiment, a medical needle shield apparatus is provided in accordance with the principles of the present disclosure. The shield is slidably movable along a medical needle from a proximal position where a distal end of the needle is exposed, to a distal position where the shield protects the distal end of the needle. The medical needle shield apparatus includes a binding member having an aperture through which the needle passes. The binding member also has binding surfaces for binding to a medical needle. The shield apparatus also includes a retainer integral with the binding member and in communication with the needle for temporarily retaining the binding surfaces in a non-binding position relative to the needle.
The shield apparatus also includes a positioning member for positioning the binding surfaces to secure the shield to the needle when a portion of the retainer in contact with the needle is advanced past the distal end of the needle and allows the retainer to release from the needle and move out of an axial path defined by the needle. The retainer may also be configured so that it does not move out of an axial path defined by the needle. A housing may be included for enclosing the shield apparatus.
In one particular embodiment, the shield apparatus includes a positioning member comprising a leaf spring integral to the binding member. Alternatively, the positioning member may comprise one or more friction elements disposed on the medical needle. In another particular embodiment, the positioning member comprises a unitary friction element disposed on the medical needle.
In another particular embodiment, the shield apparatus includes a retainer having a slot for permitting a guidewire to extend through the safety shield apparatus.

In the discussion that follows, the term "proximal" refers to a portion of a structure that is closer to a clinician, and the term "distal" refers to a portion that is further from the clinician. As used herein, the term "subject" refers to a patient that receives infusions or has blood andlor fluid collected therefrom using the medical needle shield apparatus. According to the present disclosure, the term "clinician" refers to an individual administering an infusion, performing fluid collection, installing or removing a needle cannula from a medical needle shield apparatus and may include support personnel.
-6-The following discussion includes a description of the medical needle shield apparatus, followed by a description of the method of operating the medical needle shield apparatus in accordance with the present disclosure. Reference will now be made in detail to the exemplary embodiments of the disclosure, which are illustrated in the accompanying figures.
Turning now to the figures, wherein like components are designated by like reference numerals throughout the several views. Referring initially to FIGURES 1-7, there is illustrated a safety shield assembly 10, constructed in accordance with the principals of the present disclosure, including a needle, such as, for example, medical needle 16 having a distal end 14. Safety shield assembly 10 is advantageously configured to prevent hazardous exposure to the distal end 14 of a needle cannula 16 by providing an adequate and reliable medical needle shield apparatus for a medical needle 16 which shields the distal end 14 of a needle 16, as will be discussed below.
Safety shield assembly 10 may include a housing 12 having a first section 28 and second section 30 for ease of assembly. Housing 12 includes openings 44 sized to allow the needle 16 to pass through. Safety shield 10 is disposed on a needle 16 of a medical needle device to facilitate safe disposal of a medical needle device. FIGURE 1 illustrates safety shield assembly 10 disposed near the hub 32 of on a needle having a stylet 34.
Safety shield 10 is slidably movable along a needle 16 from a proximal position where a distal end 14 of the needle 16 is exposed, to a distal position where the safety shield 10 protects the distal end 14 of the needle 16. Safety shield 10 includes a binding member 18 having an aperture 22 through which the needle 16 passes. The binding member 18 also has binding surfaces 22 for binding to a medical needle 16. The safety shield 10 also includes a retainer 24 integral with the binding member 18 and in communication with the needle 16 for temporarily retaining the binding surfaces 22 in a non-binding position relative to the needle 16. The positioning member 26 illustrated in FIGURES 1-7 comprises a leaf spring integral to the binding member 18. The safety shield 10 also includes a positioning member 26 for positioning the binding surfaces 22 in a binding orientation to secure the safety shield 10 to the needle 16 when a portion 36 of the retainer 24 in contact with the needle 16 is advanced past the distal end 14 of the needle 16 and allows the retainer 24 to release from the needle 16 and move out of an axial path defined by the needle 16. The retainer 24 may also be configured such that it does not move out of an axial path defined by the needle 16. The housing 12 may further include needle supports 38 for guiding the needle through the safety shield 10. A first blocking member 40 and second blocking member 42 urge the binding member 18 into a binding orientation. The first and second blocking members 40 and 42 may also be utilized to retain the binding member 18 to the housing 12. It is contemplated that housing 12 may also include features for retaining the binding member 18 to the housing 12. The binding member 18 makes contact with the housing 12 at first blocking member 40 and second blocking member 42. First blocking member 40 and second blocking member 42 are placed on opposite sides of, and at distances perpendicular to, the long axis of needle 16.
The binding member 18 is generally a stiff plate. The aperture 20 may be round, rectangular, or of any shape having binding surfaces 22 on opposing sides of the aperture 20.
The aperture 20 need not be closed on all sides, such as for example "U"
shaped wherein the aperture 20 may be open to one or more edges of the binding member 18. The aperture 20 is sized to allow the needle 16 to slide within the aperture 20 when the binding member 18 is positioned at one angle relative to the long axis of the needle 16 (generally close to perpendicular), and also sized so as to bring the binding surfaces 22 of the aperture 20 into binding contact with the needle 16 when the binding member 18 is positioned at a different angle relative to the long axis of the needlel6. This angle is referred to as the binding orientation.
As the safety shield 10 is urged in the proximal direction, first blocking member 40 urges the binding member 18 in a direction tending toward the binding orientation (see FIGURE 6). As the safety shield 10 is urged in the distal direction, second blocking member 42 urges the binding member 18 in a direction tending toward the binding orientation (see FIGURE 7).
The portion 36 on the retainer 24 in communication with the needle 16 is positioned such that when it is in contact with the needle 16, the binding member 18 is in a sliding orientation relative to the needle 16. Portion 36, by virtue of its contact with needle 16, maintains the sliding orientation of the binding member 18 by opposing the force provided by the positioning member 26, which would otherwise urge the binding member 18 into the binding position. As the safety shield 10 is moved towards the distal end 14 of the needle 16 and positioned such that portion 36 is distal of the distal end 14 of the needle 16, the binding member 18 is free to move into the binding orientation as urged by the positioning member 26. In this particular embodiment, portion 36 is a portion of a circular hole, but other surfaces may be utilized to accomplish the same function.
The positioning member 26 extends from the binding member 18, and is configured such that when the binding member 18 is in the sliding orientation, the positioning member 26 is slideably in contact with, and compressed against, the needle 16 in such a way as to provide a force tending to urge the binding member 18 into the binding orientation, but selectably opposed by portion 36 as described above. The binding member 18 may be _g_ unitary with a resilient positioning member 26. The positioning member 26 may take other resilient shapes such as a coil or accordion. Other portions of the binding member 18 may be more stiff, which may be accomplished by varying the geometry such as the thickness, width, etc.
Binding of the binding member 18 to the needle 16 is a function of the friction force generated between the aperture binding surfaces 22 and the needle 16. Sharp edges are advantageous, but not required. The friction force generated is a function of the aperture 20 dimension, the needle 16 diameter, the binding member 18 thickness, the distance between the first and second blocking members 40 and 42 to the centerline of the needle 16, and the coefficient of friction between the aperture 20 and the needle 16. One skilled in the art may easily derive an equation demonstrating that these key elements may be arranged in such a way as to ensure that the friction force generated will always be sufficient to bind the binding member 18 to the needle 18 for any force applied to the safety shield 10 up to the point of material failure of at least one of the elements.
Safety shield 10 can be fabricated from a material suitable for medical applications, such as, for example, polymerics or metals, such as stainless steel, depending on the particular medical application and/or preference of a clinician. Semi-rigid and rigid polymerics are contemplated for fabrication, as well as resilient materials, such as molded medical grade polypropylene. However, one skilled in the art will realize that other materials and fabrication methods suitable for assembly and manufacture, in accordance with the present disclosure, also would be appropriate.
Safety shield 10 may also be adapted for use with a medical needle device having a guidewire introducer, such as a Seldinger needle. An alternate embodiment of retainer 24' is shown in FIGURE 8, which includes a slot 46 for permitting a guidewire, stylet, or other element passed through the bore of needle 16, to extend through the safety shield 10. Similar to the binding member 18 shown in FIGURES 1-7, the binding member 18' includes an aperture 22' through which the needle 16 passes. The binding member 18' also has binding surfaces 22' for binding to a medical needle 16. A retainer 24' integral with the binding member 18' communicates with the needle 16 for temporarily retaining the binding surfaces 22' in a non-binding position relative to the needle 16. The positioning member 26' illustrated in FIGURE 8 comprises a leaf spring integral to the binding member 18'.
Positioning member 26' positions the binding surfaces 22' to secure the safety shield 10' to the needle 16 when a portion 36' of the retainer 24' in contact with the needle 16 is advanced past the distal end 14 of the needle 16 and allows the retainer 24' to release from the needle 16 and move out of an axial path defined by the needle 16.
_9_ An alternate embodiment of retainer 24" is illustrated in FIGURES 9-13, wherein the portion 36" on retainer 24" in communication with needle 16 comprises a planar surface in contact with the needle 16. Safety shield 10' is slidably movable along a needle 16 from a proximal position where a distal end 14 of the needle 16 is exposed, to a distal position where the safety shield 10' protects the distal end 14 of the needle 16. Safety shield 10' includes a binding member 18" having an aperture 22" through which the needle 16 passes.
The binding member 18" also has binding surfaces 22" for binding to a medical needle 16.
The safety shield 10' also includes a retainer 24" integral with the binding member 18"
and in communication with the needle 16 for temporarily retaining the binding surfaces 22" in a non-binding position relative to the needle 16. The positioning member 26"
illustrated in FIGURES 9-13 comprises a leaf spring integral to the binding member 18". The safety shield 10' also includes a positioning member 26" for positioning the binding surfaces 22" to secure the safety shield 10' to the needle 16 when a portion 36" of the retainer 24"
in contact with the needle 16 is advanced past the distal end 14 of the needle 16 and allows the retainer 24" to release from the needle 16 and move out of an axial path defined by the needle 16. The housing 12 may further include needle supports 38 for guiding the needle 16 through the safety shield 10'. A first blocking member 40 and second blocking member 42 may be provided to urge the binding member 18" into a binding orientation. First blocking member 40 urges the binding member 18" into a binding orientation as it is moved towards the , proximal end of needle 16, as shown in FIGURE 10. Second blocking member 42 urges the binding member 18" into a binding orientation as it is moved towards the distal end 14 of needle 16, as shown in FIGURE 11.
An alternate embodiment of positioning member is illustrated in FIGURES 14-17, wherein the positioning member comprises friction elements 48 having a sliding friction fit on the needle 16. Safety shield 10" is slidably movable along a needle 16 from a proximal position where a distal end 14 of the needle 16 is exposed, to a distal position where the safety shield 10" protects the distal end 14 of the needle 16. Safety shield 10" includes a binding member 18"' having an aperture 22"' through which the needle 16 passes. The binding member 18"' also has binding surfaces 22"' for binding to a medical needle 16. The safety shield 10" also includes a retainer 24"' integral with the binding member 18"' and in communication with the needle 16 for temporarily retaining the binding surfaces 22"' in a non-binding position relative to the needle 16. The combination of the force generated by the friction elements 48, the force input from the first blocking member 40 or second blocking member 42 upon interface with binding member 18"', and the lever or moment arm formed by the binding member 18"' forms a couple which provides a force tending to urge the binding member 18"' into binding orientation. The friction elements 48 thus position the binding surfaces 22"' to secure the safety shield 10" to the needle 16 when a portion 36"' of the retainer 24"' in contact with the needle 16 is advanced past the distal end 14 of the needle 16 and allows the retainer 24"' to release from the needle 16. The housing 12 may further include needle supports 38 for guiding the needle 16 through the safety shield 10". A first blocking member 40 and second blocking member 42 may be provided to urge the binding member 18"' into binding orientation.' First blocking member 40 urges binding member 18"' into a binding orientation as it is moved towards the proximal end of needle 16, as shown in FIGURE 15. Second blocking member 42 urges binding member 18"' into a binding orientation as it is moved towards the distal end 14 of needle 16, as shown in FIGURE 16.
The friction elements 48, as described above, may be joined to create a unitary friction element 50 as shown in FIGURES 18-21. Safety shield 10"' is slidably movable along a needle 16 from a proximal position where a distal end 14 of the needle 16 is exposed, to a distal position where the safety shield 10"' protects the distal end 14 of the needle 16.
Safety shield 10"' includes a binding member 18"' having an aperture 22"' through which the needle 16 passes. The binding member 18"' also has binding surfaces 22"' for binding to a medical needle 16. The safety shield 10"' also includes a retainer 24"' integral with the binding member 18"' and in communication with the needle 16 for temporarily retaining the binding surfaces 22"' in a non-binding position relative to the needle 16. The combination of the force generated by the first surface 52 and second surface 54 of unitary friction elements 50, the force input from the first blocking member 40 or second blocking member 42 upon interface with binding member 18"', and the lever or moment arm formed by the binding member 18"' forms a couple which provides a force tending to urge the binding member 18"' into binding orientation. It is also contemplated that other geometries may be utilized which accomplish the same function as first surface 52 and second surface 54. The unitary friction element 50 thus positions the binding surfaces 22"' to secure the safety shield 10"' to the needle 16 when a portion 36"' of the retainer 24"' in contact with the needle 16 is advanced past the distal end 14 of the needle 16 and allows the retainer 24"' to release from the needle 16. The housing 12 may further include needle supports 38 for guiding the needle 16 through the safety shield 10"'. A first blocking member 40 and second blocking member 42 may be provided to urge the binding member 18"' into binding orientation. First blocking member 40 urges the binding member 18"' into a binding orientation as it is moved towards the proximal end of needle 16, as shown in FIGURE 19. Second blocking member 42 urges the binding member 18"' into a binding orientation as it is moved towards the distal end 14 of needle 16, as shown in FIGURE 20.
The binding member 18"' and portion 36"' on retainer 24"' may include "U"
shaped apertures 19 and 37 respectively, as well as "U" shaped openings 53 and 55 on first surface 52 and second surface 54 respectively, to provide side installation of the needle 16 during assembly of the safety shield 10"'.
Safety shields 10" and 10"' may also be adapted for use with a medical needle device having a guidewire introducer, such as a Seldinger needle. An alternate embodiment of retainer 24"' is shown in FIGURE 22, which includes a slot 46' for permitting a guidewire to extend through the safety shield 10" or 10"'. Similar to the binding members 18" and 18"' shown in FIGURES 14-21, the binding member 18"' includes an aperture 22"' through which the needle 16 passes. The binding member 18"' also has binding surfaces 22"' for binding to a medical needle 16. A retainer 24"' integral with the binding member 18"' communicates with the needle 16 for temporarily retaining the binding surfaces 22"' in a non-binding position relative to the needle 16.
The friction elements 62 may also be integral to the binding member 64 as shown in FIGURES 23-27. Other friction element 62 configurations are contemplated which accomplish the same function of creating drag on the needle in such a way as to selectably promote binding. Safety shield 60 is slidably movable along a needle 16 from a proximal position where a distal end 14 of the needle 16 is exposed, to a distal position where the safety shield 60 protects the distal end 14 of the needle 16. Safety shield 60 includes a binding member 64 having an aperture 66 through which the needle 16 passes.
The binding member 64 also has binding surfaces 68 for binding to a medical needle 16. The safety shield 60 also includes a retainer 70 integral with the binding member 64 and in communication with the needle 16 for temporarily retaining the binding surfaces 68 in a non-binding position relative to the needle 16. The combination of the force generated by the friction elements 62, the force input from the first blocking member 40 or second blocking member 42 upon interface with binding member 64, and the lever or moment arm formed by the binding member 64 forms a couple which provides a force tending to urge the binding member 64 into a binding orientation. The friction elements 62 thus position the binding surfaces 68 to secure the safety shield 60 to the needle 16 when a portion 72 of the retainer 70 in contact with the needle 16 is advanced past the distal end 14 of the needle 16 and allows the retainer 70 to release from the needle 16. The housing 12 may further include needle supports 38 for guiding the needle 16 through the safety shield 60. A first blocking member 40 and second blocking member 42 may be provided to urge the binding member 64 into a binding orientation. First blocking member 40 urges the binding member 64 into a binding orientation as it is moved towards the proximal end of needle 16, as shown in FIGURE 24.
Second blocking member 42 urges the binding member 64 into a binding orientation and retains housing 12 to the safety shield 60 as it is moved towards the distal end 14 of needle 16, as shown in FIGURE 25.
Safety shield 60 may also be adapted for use with a medical needle device having a guidewire 76, as shown in FIGURE 28. An alternate embodiment of retainer 70 is shown in FIGURES 27 and 28, which includes a slot 46" for permitting a guidewire to extend through the safety shield 60. Similar to the binding member 64 shown in FIGURES 23-26, the binding member 64' includes an aperture 66' through which the needle 16 passes. The binding member 64' also has binding surfaces 68' for binding to a medical needle 16. A
retainer 70' integral with the binding member 64' communicates with the needle 16 for temporarily retaining the binding surfaces 68' in a non-binding position relative to the needle 16.
It is contemplated that the present invention may include multiple safety shields for protecting the needle 16 and a stylet 84 or other element passed through a bore of the needle 16.
FIGURE 29 is a perspective view of a safety shield apparatus having a first safety shield assembly 80 and a second safety shield assembly 82 for protecting a distal end 86 of a stylet 84 passed through a bore of the needle 16. FIGURE 30 is a perspective view of the first and second safety shield assemblies 80 and 82, respectively, after actuation protecting the distal end 14 of a needle 16 and the distal end 86 of a stylet 84 after use. First and second safety shields 80 and 82 illustrated in FIGURE 30 are similar to safety shield assembly 60 shown in FIGURE 28.
However, any of the above described safety shield assemblies may be utilized.
The invention of the present disclosure may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
Turning now to the figures, wherein like components are designated by like reference numerals throughout the several views. Referring initially to FIGURES 1-7, there is illustrated a safety shield assembly 10, constructed in accordance with the principals of the present disclosure, including a needle, such as, for example, medical needle 16 having a distal end 14. Safety shield assembly 10 is advantageously configured to prevent hazardous exposure to the distal end 14 of a needle cannula 16 by providing an adequate and reliable medical needle shield apparatus for a medical needle 16 which shields the distal end 14 of a needle 16, as will be discussed below.
Safety shield assembly 10 may include a housing 12 having a first section 28 and second section 30 for ease of assembly. Housing 12 includes openings 44 sized to allow the needle 16 to pass through. Safety shield 10 is disposed on a needle 16 of a medical needle device to facilitate safe disposal of a medical needle device. FIGURE 1 illustrates safety shield assembly 10 disposed near the hub 32 of on a needle having a stylet 34.
Safety shield 10 is slidably movable along a needle 16 from a proximal position where a distal end 14 of the needle 16 is exposed, to a distal position where the safety shield 10 protects the distal end 14 of the needle 16. Safety shield 10 includes a binding member 18 having an aperture 22 through which the needle 16 passes. The binding member 18 also has binding surfaces 22 for binding to a medical needle 16. The safety shield 10 also includes a retainer 24 integral with the binding member 18 and in communication with the needle 16 for temporarily retaining the binding surfaces 22 in a non-binding position relative to the needle 16. The positioning member 26 illustrated in FIGURES 1-7 comprises a leaf spring integral to the binding member 18. The safety shield 10 also includes a positioning member 26 for positioning the binding surfaces 22 in a binding orientation to secure the safety shield 10 to the needle 16 when a portion 36 of the retainer 24 in contact with the needle 16 is advanced past the distal end 14 of the needle 16 and allows the retainer 24 to release from the needle 16 and move out of an axial path defined by the needle 16. The retainer 24 may also be configured such that it does not move out of an axial path defined by the needle 16. The housing 12 may further include needle supports 38 for guiding the needle through the safety shield 10. A first blocking member 40 and second blocking member 42 urge the binding member 18 into a binding orientation. The first and second blocking members 40 and 42 may also be utilized to retain the binding member 18 to the housing 12. It is contemplated that housing 12 may also include features for retaining the binding member 18 to the housing 12. The binding member 18 makes contact with the housing 12 at first blocking member 40 and second blocking member 42. First blocking member 40 and second blocking member 42 are placed on opposite sides of, and at distances perpendicular to, the long axis of needle 16.
The binding member 18 is generally a stiff plate. The aperture 20 may be round, rectangular, or of any shape having binding surfaces 22 on opposing sides of the aperture 20.
The aperture 20 need not be closed on all sides, such as for example "U"
shaped wherein the aperture 20 may be open to one or more edges of the binding member 18. The aperture 20 is sized to allow the needle 16 to slide within the aperture 20 when the binding member 18 is positioned at one angle relative to the long axis of the needle 16 (generally close to perpendicular), and also sized so as to bring the binding surfaces 22 of the aperture 20 into binding contact with the needle 16 when the binding member 18 is positioned at a different angle relative to the long axis of the needlel6. This angle is referred to as the binding orientation.
As the safety shield 10 is urged in the proximal direction, first blocking member 40 urges the binding member 18 in a direction tending toward the binding orientation (see FIGURE 6). As the safety shield 10 is urged in the distal direction, second blocking member 42 urges the binding member 18 in a direction tending toward the binding orientation (see FIGURE 7).
The portion 36 on the retainer 24 in communication with the needle 16 is positioned such that when it is in contact with the needle 16, the binding member 18 is in a sliding orientation relative to the needle 16. Portion 36, by virtue of its contact with needle 16, maintains the sliding orientation of the binding member 18 by opposing the force provided by the positioning member 26, which would otherwise urge the binding member 18 into the binding position. As the safety shield 10 is moved towards the distal end 14 of the needle 16 and positioned such that portion 36 is distal of the distal end 14 of the needle 16, the binding member 18 is free to move into the binding orientation as urged by the positioning member 26. In this particular embodiment, portion 36 is a portion of a circular hole, but other surfaces may be utilized to accomplish the same function.
The positioning member 26 extends from the binding member 18, and is configured such that when the binding member 18 is in the sliding orientation, the positioning member 26 is slideably in contact with, and compressed against, the needle 16 in such a way as to provide a force tending to urge the binding member 18 into the binding orientation, but selectably opposed by portion 36 as described above. The binding member 18 may be _g_ unitary with a resilient positioning member 26. The positioning member 26 may take other resilient shapes such as a coil or accordion. Other portions of the binding member 18 may be more stiff, which may be accomplished by varying the geometry such as the thickness, width, etc.
Binding of the binding member 18 to the needle 16 is a function of the friction force generated between the aperture binding surfaces 22 and the needle 16. Sharp edges are advantageous, but not required. The friction force generated is a function of the aperture 20 dimension, the needle 16 diameter, the binding member 18 thickness, the distance between the first and second blocking members 40 and 42 to the centerline of the needle 16, and the coefficient of friction between the aperture 20 and the needle 16. One skilled in the art may easily derive an equation demonstrating that these key elements may be arranged in such a way as to ensure that the friction force generated will always be sufficient to bind the binding member 18 to the needle 18 for any force applied to the safety shield 10 up to the point of material failure of at least one of the elements.
Safety shield 10 can be fabricated from a material suitable for medical applications, such as, for example, polymerics or metals, such as stainless steel, depending on the particular medical application and/or preference of a clinician. Semi-rigid and rigid polymerics are contemplated for fabrication, as well as resilient materials, such as molded medical grade polypropylene. However, one skilled in the art will realize that other materials and fabrication methods suitable for assembly and manufacture, in accordance with the present disclosure, also would be appropriate.
Safety shield 10 may also be adapted for use with a medical needle device having a guidewire introducer, such as a Seldinger needle. An alternate embodiment of retainer 24' is shown in FIGURE 8, which includes a slot 46 for permitting a guidewire, stylet, or other element passed through the bore of needle 16, to extend through the safety shield 10. Similar to the binding member 18 shown in FIGURES 1-7, the binding member 18' includes an aperture 22' through which the needle 16 passes. The binding member 18' also has binding surfaces 22' for binding to a medical needle 16. A retainer 24' integral with the binding member 18' communicates with the needle 16 for temporarily retaining the binding surfaces 22' in a non-binding position relative to the needle 16. The positioning member 26' illustrated in FIGURE 8 comprises a leaf spring integral to the binding member 18'.
Positioning member 26' positions the binding surfaces 22' to secure the safety shield 10' to the needle 16 when a portion 36' of the retainer 24' in contact with the needle 16 is advanced past the distal end 14 of the needle 16 and allows the retainer 24' to release from the needle 16 and move out of an axial path defined by the needle 16.
_9_ An alternate embodiment of retainer 24" is illustrated in FIGURES 9-13, wherein the portion 36" on retainer 24" in communication with needle 16 comprises a planar surface in contact with the needle 16. Safety shield 10' is slidably movable along a needle 16 from a proximal position where a distal end 14 of the needle 16 is exposed, to a distal position where the safety shield 10' protects the distal end 14 of the needle 16. Safety shield 10' includes a binding member 18" having an aperture 22" through which the needle 16 passes.
The binding member 18" also has binding surfaces 22" for binding to a medical needle 16.
The safety shield 10' also includes a retainer 24" integral with the binding member 18"
and in communication with the needle 16 for temporarily retaining the binding surfaces 22" in a non-binding position relative to the needle 16. The positioning member 26"
illustrated in FIGURES 9-13 comprises a leaf spring integral to the binding member 18". The safety shield 10' also includes a positioning member 26" for positioning the binding surfaces 22" to secure the safety shield 10' to the needle 16 when a portion 36" of the retainer 24"
in contact with the needle 16 is advanced past the distal end 14 of the needle 16 and allows the retainer 24" to release from the needle 16 and move out of an axial path defined by the needle 16. The housing 12 may further include needle supports 38 for guiding the needle 16 through the safety shield 10'. A first blocking member 40 and second blocking member 42 may be provided to urge the binding member 18" into a binding orientation. First blocking member 40 urges the binding member 18" into a binding orientation as it is moved towards the , proximal end of needle 16, as shown in FIGURE 10. Second blocking member 42 urges the binding member 18" into a binding orientation as it is moved towards the distal end 14 of needle 16, as shown in FIGURE 11.
An alternate embodiment of positioning member is illustrated in FIGURES 14-17, wherein the positioning member comprises friction elements 48 having a sliding friction fit on the needle 16. Safety shield 10" is slidably movable along a needle 16 from a proximal position where a distal end 14 of the needle 16 is exposed, to a distal position where the safety shield 10" protects the distal end 14 of the needle 16. Safety shield 10" includes a binding member 18"' having an aperture 22"' through which the needle 16 passes. The binding member 18"' also has binding surfaces 22"' for binding to a medical needle 16. The safety shield 10" also includes a retainer 24"' integral with the binding member 18"' and in communication with the needle 16 for temporarily retaining the binding surfaces 22"' in a non-binding position relative to the needle 16. The combination of the force generated by the friction elements 48, the force input from the first blocking member 40 or second blocking member 42 upon interface with binding member 18"', and the lever or moment arm formed by the binding member 18"' forms a couple which provides a force tending to urge the binding member 18"' into binding orientation. The friction elements 48 thus position the binding surfaces 22"' to secure the safety shield 10" to the needle 16 when a portion 36"' of the retainer 24"' in contact with the needle 16 is advanced past the distal end 14 of the needle 16 and allows the retainer 24"' to release from the needle 16. The housing 12 may further include needle supports 38 for guiding the needle 16 through the safety shield 10". A first blocking member 40 and second blocking member 42 may be provided to urge the binding member 18"' into binding orientation.' First blocking member 40 urges binding member 18"' into a binding orientation as it is moved towards the proximal end of needle 16, as shown in FIGURE 15. Second blocking member 42 urges binding member 18"' into a binding orientation as it is moved towards the distal end 14 of needle 16, as shown in FIGURE 16.
The friction elements 48, as described above, may be joined to create a unitary friction element 50 as shown in FIGURES 18-21. Safety shield 10"' is slidably movable along a needle 16 from a proximal position where a distal end 14 of the needle 16 is exposed, to a distal position where the safety shield 10"' protects the distal end 14 of the needle 16.
Safety shield 10"' includes a binding member 18"' having an aperture 22"' through which the needle 16 passes. The binding member 18"' also has binding surfaces 22"' for binding to a medical needle 16. The safety shield 10"' also includes a retainer 24"' integral with the binding member 18"' and in communication with the needle 16 for temporarily retaining the binding surfaces 22"' in a non-binding position relative to the needle 16. The combination of the force generated by the first surface 52 and second surface 54 of unitary friction elements 50, the force input from the first blocking member 40 or second blocking member 42 upon interface with binding member 18"', and the lever or moment arm formed by the binding member 18"' forms a couple which provides a force tending to urge the binding member 18"' into binding orientation. It is also contemplated that other geometries may be utilized which accomplish the same function as first surface 52 and second surface 54. The unitary friction element 50 thus positions the binding surfaces 22"' to secure the safety shield 10"' to the needle 16 when a portion 36"' of the retainer 24"' in contact with the needle 16 is advanced past the distal end 14 of the needle 16 and allows the retainer 24"' to release from the needle 16. The housing 12 may further include needle supports 38 for guiding the needle 16 through the safety shield 10"'. A first blocking member 40 and second blocking member 42 may be provided to urge the binding member 18"' into binding orientation. First blocking member 40 urges the binding member 18"' into a binding orientation as it is moved towards the proximal end of needle 16, as shown in FIGURE 19. Second blocking member 42 urges the binding member 18"' into a binding orientation as it is moved towards the distal end 14 of needle 16, as shown in FIGURE 20.
The binding member 18"' and portion 36"' on retainer 24"' may include "U"
shaped apertures 19 and 37 respectively, as well as "U" shaped openings 53 and 55 on first surface 52 and second surface 54 respectively, to provide side installation of the needle 16 during assembly of the safety shield 10"'.
Safety shields 10" and 10"' may also be adapted for use with a medical needle device having a guidewire introducer, such as a Seldinger needle. An alternate embodiment of retainer 24"' is shown in FIGURE 22, which includes a slot 46' for permitting a guidewire to extend through the safety shield 10" or 10"'. Similar to the binding members 18" and 18"' shown in FIGURES 14-21, the binding member 18"' includes an aperture 22"' through which the needle 16 passes. The binding member 18"' also has binding surfaces 22"' for binding to a medical needle 16. A retainer 24"' integral with the binding member 18"' communicates with the needle 16 for temporarily retaining the binding surfaces 22"' in a non-binding position relative to the needle 16.
The friction elements 62 may also be integral to the binding member 64 as shown in FIGURES 23-27. Other friction element 62 configurations are contemplated which accomplish the same function of creating drag on the needle in such a way as to selectably promote binding. Safety shield 60 is slidably movable along a needle 16 from a proximal position where a distal end 14 of the needle 16 is exposed, to a distal position where the safety shield 60 protects the distal end 14 of the needle 16. Safety shield 60 includes a binding member 64 having an aperture 66 through which the needle 16 passes.
The binding member 64 also has binding surfaces 68 for binding to a medical needle 16. The safety shield 60 also includes a retainer 70 integral with the binding member 64 and in communication with the needle 16 for temporarily retaining the binding surfaces 68 in a non-binding position relative to the needle 16. The combination of the force generated by the friction elements 62, the force input from the first blocking member 40 or second blocking member 42 upon interface with binding member 64, and the lever or moment arm formed by the binding member 64 forms a couple which provides a force tending to urge the binding member 64 into a binding orientation. The friction elements 62 thus position the binding surfaces 68 to secure the safety shield 60 to the needle 16 when a portion 72 of the retainer 70 in contact with the needle 16 is advanced past the distal end 14 of the needle 16 and allows the retainer 70 to release from the needle 16. The housing 12 may further include needle supports 38 for guiding the needle 16 through the safety shield 60. A first blocking member 40 and second blocking member 42 may be provided to urge the binding member 64 into a binding orientation. First blocking member 40 urges the binding member 64 into a binding orientation as it is moved towards the proximal end of needle 16, as shown in FIGURE 24.
Second blocking member 42 urges the binding member 64 into a binding orientation and retains housing 12 to the safety shield 60 as it is moved towards the distal end 14 of needle 16, as shown in FIGURE 25.
Safety shield 60 may also be adapted for use with a medical needle device having a guidewire 76, as shown in FIGURE 28. An alternate embodiment of retainer 70 is shown in FIGURES 27 and 28, which includes a slot 46" for permitting a guidewire to extend through the safety shield 60. Similar to the binding member 64 shown in FIGURES 23-26, the binding member 64' includes an aperture 66' through which the needle 16 passes. The binding member 64' also has binding surfaces 68' for binding to a medical needle 16. A
retainer 70' integral with the binding member 64' communicates with the needle 16 for temporarily retaining the binding surfaces 68' in a non-binding position relative to the needle 16.
It is contemplated that the present invention may include multiple safety shields for protecting the needle 16 and a stylet 84 or other element passed through a bore of the needle 16.
FIGURE 29 is a perspective view of a safety shield apparatus having a first safety shield assembly 80 and a second safety shield assembly 82 for protecting a distal end 86 of a stylet 84 passed through a bore of the needle 16. FIGURE 30 is a perspective view of the first and second safety shield assemblies 80 and 82, respectively, after actuation protecting the distal end 14 of a needle 16 and the distal end 86 of a stylet 84 after use. First and second safety shields 80 and 82 illustrated in FIGURE 30 are similar to safety shield assembly 60 shown in FIGURE 28.
However, any of the above described safety shield assemblies may be utilized.
The invention of the present disclosure may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
