  • Each valve comprises a “finger” that can alternate between two positions. In one position, the finger is extended from the valve so as to contact the conduit and to at least partially occlude the conduit at the point of contact. In the other position, the finger is retracted and does not contact the conduit.

  • This door is a frequent cause of failure in the pump's operation: the door is frequently opened while the pump is in action, thus causing the conduit to fall out of place and cease pumping, opening the door and holding it open so as to insert the pipe requires three pairs of hands and thus can only be performed by two persons together necessitating the presence of two medical personnel.
  • the conduit pipe is exposed, i.e; is not wrapped or coated in any other material and is thus more vulnerable to contamination.

Since it is common hospital practice to make use of a single pipe during the course of a patient's hospitalization, without replacing the pipe, during the course of use the pipe becomes increasingly vulnerable to puncturing, thus enabling contaminants (such as blood, HIV, Hepatitis virus, radioactive medicaments etc.) which may be present in the patients bloodstream or in the infusion being delivered, to accumulate on the outer surface of the pipe. If the pipe is inadvertently touched by unprotected hospital personnel, the user himself or his visitors, such contaminants may rapidly spread and be transmitted to a wider population.

Each of the aforementioned applications is hereby incorporated into this application by reference in its entirety.
    • FIELD OF THE INVENTION
  • The present invention relates to pumps and more specifically to finger-type peristaltic pumps.
    • BACKGROUND OF THE INVENTION
  • Peristaltic pumps are used for creating a flow of a fluid in an elastic tubular conduit. These pumps have many medical and industrial applications.
  • In one form of peristaltic pumps, a rotor is used to rotate a plurality of eccentric cams. Each cam, in turn, intermittently collapses the elastic conduit at an initial contact point, and slides along the conduit over a short distance as the rotor turns. A second cam contacts the initial contact point, and the first cam is then released from the conduit as the second cam slides along the conduit. As this process is repeated, a flow of fluid in the conduit is generated in the direction of the sliding of the cams.
  • In another form of peristaltic pumps referred to herein as a “finger-type peristaltic pump”, a series of valves is aligned along an elastic conduit. Each valve comprises a “finger” that can alternate between two positions. In one position, the finger is extended from the valve so as to contact the conduit and to at least partially occlude the conduit at the point of contact. In the other position, the finger is retracted and does not contact the conduit. The series of valves is operated according to a temporo-spatial pattern so as to generate a flow in the conduit.
  • Commercially-available finger-type peristaltic pumps essentially include a hinged door, which is usually a rotatable member, adapted to continuously press the fluid conduit inserted in the body towards the valve fingers located in the body when it is closed configuration. This door is a frequent cause of failure in the pump's operation: the door is frequently opened while the pump is in action, thus causing the conduit to fall out of place and cease pumping, opening the door and holding it open so as to insert the pipe requires three pairs of hands and thus can only be performed by two persons together necessitating the presence of two medical personnel.
  • In addition, in this configuration the conduit pipe is exposed, i.e; is not wrapped or coated in any other material and is thus more vulnerable to contamination. The pipe is normally made of thin flexible silicone, which is worn down by the tip of the finger pump during extended use. Since it is common hospital practice to make use of a single pipe during the course of a patient's hospitalization, without replacing the pipe, during the course of use the pipe becomes increasingly vulnerable to puncturing, thus enabling contaminants (such as blood, HIV, Hepatitis virus, radioactive medicaments etc.) which may be present in the patients bloodstream or in the infusion being delivered, to accumulate on the outer surface of the pipe. If the pipe is inadvertently touched by unprotected hospital personnel, the user himself or his visitors, such contaminants may rapidly spread and be transmitted to a wider population.
  • The configurations currently available comprise three separate components: body, conduit and door. Inserting the conduit into the body, and then closing the door accurately requires considerable experience and manual dexterity, and can not normally be performed by chronically ill, physically limited or geriatric patients independently, thus requiring the constant attention of hospital personnel.
  • U.S. Pat. No. 5,395,320 to Padda et al. teaches a programmable peristaltic fingers infusion pump with an interchangeable variety of disposable tubing in commonly available sizes and types. The pump essentially comprises no less than two doors: an outer door (1) and an inner door (20), wherein the outer door (1) protects the inner door (20), which is kept in a close configuration by door latch (2).
  • U.S. Pat. No. 5,807,322 to Lindsey et al. presents a peristaltic pump unit that has a flexible infusion line (28) which is repeatedly compressed by a pusher (30). Line (28) is positioned in an elongated groove or channel (58) which acts to restrain sideways bulging of the line as it is being compressed by the pusher. The patent teaches that peristaltic pumps may be associated with a cassette which acts as a reservoir for the fluid to be pumped.
  • FR 2,753,236 to Ray et al. introduces a miniature peristaltic pump. The pump comprises inter alia a rotor, and a support piece equipped with a rounded-off portion (308) arranged in a substantially concentric manner to the rotor and against which, during operation, said rollers compress a flexible tubing (202) connected to a solution reservoir (201). Tubing (202) is inserted into circular opening (310), closed off by a cover (311). Thus again, slidable door member (311) ensures conduit (202) location directly adjacent to the pumping effecters (here rollers 110). Again the body and the door are integrally attached.
  • FR 2,632,529 to Gautier et al. teaches a drug injector with a removable reservoir in which the infusion liquid container may be inserted—held to control box by a pivoting arm engaged by head. The patent discloses a pump having a body (2) and rotatable pumping effecter (pump drum 7) towards which pipe (4) is pressed by means of maneuverable arm (10) being interconnected to body (2) by an hinge. Arm (10) is forcefully secured to body (2) by screw (16).
    • SUMMARY OF THE INVENTION
  • The present invention provides a finger-type peristaltic pump. The pump of the invention may be used, for example, in a medical context for infusing a liquid into the body of a subject.
  • The peristaltic pump of the invention comprises a housing for holding a segment of an elastic conduit adjacent to the fingers of the valves of the pump. In one embodiment, the housing is hinged at one end to the body of the pump. The housing is swung out from the body in order to introduce a segment of an elastic conduit into the housing. The housing is then swung back towards the body so as to position the conduit segment adjacent to the fingers of valves of the pump. The housing may be maintained in this closed position by a snapping mechanism, or by a latch.
  • In another embodiment, the housing of the invention is detachable from the body of the pump. A segment of a conduit may be introduced into the housing when the housing is detached. The housing is then attached onto the body of the pump so as to position the segment of the conduit adjacent to the valve fingers. In a most preferred embodiment, the housing is integral with a segment of a conduit. In this case, the conduit in the housing has fittings at each end allowing the conduit to be attached at each end to another piece of conduit, so that the pump may be integrated into a pumping system. In the detachable housing embodiment, the housing may be disposable.
  • The housing of the invention preferably includes an antifree-flow mechanism to prevent the flow of fluid in the segment of the conduit in the housing when the conduit is not adjacent to the fingers. The antifree-flow has a non-obstructing position in which the antifree-flow device does not prevent flow in the conduit, and an obstructing position in which the antifree-flow device prevents flow in the conduit. The antifree-flow device is spring biased in the obstructing position, so that when the housing is swung away or detached from the body of the pump, the antifree-flow device spontaneously assumes its obstructing position. This prevents unintentional flow in the conduit when the housing is swung out or detached from the body of the pump. The antifree-flow device preferably includes an override mechanism that allows the antifree-flow device to be temporarily latched in its non-obstructing position when the housing is swung away or detached from the body in order to allow a segment of conduit to be introduced into the housing. As the housing is brought to its position in which it is attached to the pump, the antifree-flow device is brought to its unlatched non-obstructing position, regardless of whether it was previously in its obstructing position or its latched non-obstructing position. The antifree flow device may prevent flow in the conduit in both directions or only in one direction.
  • Thus, in its first aspect, the invention provides a finger-type peristaltic pump comprising a body and a housing, the body containing two or more finger-type valves and a processor configured to operate the valves according to a predetermined temporo-spatial pattern, the housing having a passageway configured to receive a conduit, the housing having a first position in which a conduit in the passageway is positioned adjacent to the valve fingers, and a second position in which a conduit in the passageway is not adjacent to the valve fingers.
  • In its second aspect, the invention provides a housing for use in the pump of the invention.

    •  DETAILED DESCRIPTION OF THE INVENTION
  • FIGS. 1A and 1B show a finger-type peristaltic pump 2 in accordance with one embodiment of the invention. The pump 2 has a body 4 and a housing 6. The housing 6 is hinged to the body 4 at a hinge 8 so as to allow the housing 6 to pivot between a closed position shown in FIG. 1A and an open position shown in FIG. 1B. The housing 6 snaps into the closed position by means of projections 10 located at the end of the housing 6 distal to the hinge 8 that snaps into mated notches 12 in the body 4.
  • The housing 6 has a passageway 18 dimensioned to receive a segment of an elastic conduit as explained below.
  • The body 4 has a housing 14 containing a plurality of electrically operated valves 16. Four valves, 16 a to 16 d, are shown in FIGS. 1A and 1B. This is by way of example only and the pump may have any number of valves 16 greater than two. Each valve 16 has a respective finger 20. Each valve 16 is electrically operable to oscillate its finger 20 from a retracted position in which the finger 20 does not contact a conduit in the passageway 18 and an extended position in which the finger 20 at least partially occludes a flexible conduit in the passageway 18. The fingers 20 b and 20 d are shown in FIGS. 1A and 1B in their retracted position, while the fingers 20 a and 20 d are shown in FIGS. 1A and 1B in their extended position. Each finger 20 corresponds to a finger hole 21 in the upper surface 23 of the housing 6. A finger 16, when in its extended position, extends through its respective finger hole 20 into the housing 6 to compress a region of a conduit in the passageway 18.
  • The body 4 also contains a processor 22 configured to operate the valves 16 according to a temporo-spatial pattern so as to generate a flow of fluid in an elastic conduit in the passageway 18 when the housing 6 is in its closed position shown in FIG. 1A, as is known in the art.
  • FIG. 2 shows the housing 6 in greater detail. A conduit 24 made from an elastic material has been introduced into the passageway 18. The conduit 24 is supported in the passage 18 by one or more supports 26 that prevent bulging of the conduit 24 between two fingers 20 in the extended state. The supports 26 also prevent lateral movement of the conduit 24 in the passageway 18 during operation of the pump. The cross sectional shape of the passageway 18 is determined by the shape of holes 59 in the supports 26
  • FIG. 3 shows the pump 2 with a conduit 24 in the passageway 18 in its closed position shown also in FIG. 1A. As can be seen, the fingers 20 a and 20 c are in their extended position and therefore constrict the conduit 24 and the points of contact 25 a and 25 c. As explained above, the valves 16 are operated by the processor 22 so that the fingers 20 alternate between their retracted and extended positions so as to generate a flow in the conduit 24
  • The housing 6 includes an anti-free flow mechanism 39. The anti-free flow mechanism prevents the flow of fluid in the conduit 24 when the housing 6 is not in its closed position shown in FIG. 1B. The anti-free flow mechanism is shown in FIGS. 4A-4B in a cross section AA′ of the pump 2 shown in FIG. 3. The housing 6 is shown in its open position in FIG. 4A and in its closed position in FIG. 4B. The anti-free flow includes an occlusion plate 32, from which an actuating tab 34 extends (see also FIGS. 1A, 1B and 2). The occluding plate 32 has a D-shaped hole 36 having a straight bottom edge 37 and an upper arcuate edge 35. A hole 59 of the passageway 18 is indicated in FIG. 4A by a broken line. The holes 59 of the passageway 18 are “D” shaped, having a straight upper edge 41 and an arcuate lower edge 47. The occluding plate is slidable from an obstructing position shown in FIG. 4A and a non-obstructing position shown in FIG. 4B. The occluding plate 32 is spring biased in its obstructing position by means of springs 38. In its non-obstructing position (FIG. 4B), the hole 36 of the occlusion plate 32 is essentially aligned with the passageway 18 so that the conduit 24 is unobstructed. In its obstructing position (FIG. A), the hole 36 and the passageway 18 only partially overlap, so that the conduit 24 is collapsed between the straight edge 37 of the hole 36 and the straight edge 41 of the passageway 18. The conduit 24 is thus obstructed, as shown in FIG. 4A. This prevents unintentional flow of fluid in the conduit 24 when the housing 6 is swung out from the body 4.
  • When the housing 6 is swung out from the body 4, the obstructing plate 32 may be brought into its non-obstructing position (FIG. 4B) by manually depressing the tab 34. The tab 34 may be temporarily latched with the plate 32 in its non-obstructing position. This may be done for example, when it is desired to allow free flow of fluid in the conduit. The plate 32 in its latched non-obstructing position is shown in a side view in FIG. 4C. Extensions 51 on either side of the tab 34 (see also FIGS. 4A and 4B) are lodged under extensions 53 of the inner wall of the housing 6. The obstructing plate 32 is brought into its latched non-obstructing position (FIG. 4A) from its unlatched non-obstructing position (FIG. 4B) by rotating the plate 32 so as to lodge the extensions 51 under the extensions 53. An upwards pressure on the plate 32 by the springs 38 presses the extensions 51 onto the extensions 53 so as to maintain the anti-free-flow mechanism in its latched non-obstructing state. The obstructing plate 32 may be manually released from its lodged, non-obstructing position by rotating the plate 32 back so as to dislodge the extensions 51 from under the extensions 53. The plate 32 then passes through a slot 57 in the housing 6 in order to regain its obstructing position (FIG. 4A) under the influence of the spring 38. The housing 6 is then swung shut onto the body 4 (FIG. 4B). If the anti-free flow mechanism is in its latched non-obstructing position when the housing is swung onto the body 4, a pair of wedges 55 extending from the body 4 (FIG. 1B) rotate the plate 32 as the housing 6 is being swung shut so as to dislodge the extensions 51 from under the extensions 53. A static plate 40 fixed in the body 4 depresses the tab 34 against the spring 38 so to maintain the plate 32 in its unlatched non-obstructing position when the housing 6 is in its closed position.
  • FIGS. 5A-5B show a finger-type peristaltic pump 2′ in accordance with another embodiment of the invention. Components of the pump 2′ similar to components of the pump 2 are designated by the same reference numerals without further comment. The pump 2′ has a body 4′ and a housing 6′. The housing 6′ is reversibly attachable to the body 4′ by means of projections 10′ located at both ends of the housing 6′ that snap into mated notches 12′ on opposite sides of the body 4′. In FIG. 5A, the housing 6′ is shown attached to the body 4′, and in FIG. 5B, the housing 6′ is shown detached from the body 4′. The pump 2′ is operated as described above in reference to the pump 2. The housing 6′ may be disposable.
  • FIG. 6 shows a housing 6″ that may be used with the body 4′ instead of the housing 6′. Components of the housing 6″ similar to components of the housing 6′ are designated by the same reference numerals without further comment. The housing 6″ is integral with an elastic conduit 24′. The conduit 24′ is provided at one end with a connector 42 suitable for forming a fluid connection with an upstream fluid reservoir, such as an infusion bag (not shown). The other end of the conduit 24′ is provided with a connector 45 for forming a fluid connection with a downstream device, such as a needle (not shown).
  • FIG. 7 shows a housing 6″' that may be used with the body 4′ instead of the housing 6′. Components of the housing 6″ similar to components of the housing 6′ are designated by the same reference numerals without further comment. The housing 6″ is integral with an elastic conduit 24″. The conduit 24″ is integral with an upstream fluid reservoir, such as an infusion bag 44. The other end of the conduit 24″ is provided with a connector 45′ for forming a fluid connection with a downstream device, such as a needle (not shown).
