A device for measuring the length of a stoma is disclosed. A method to utilize the stoma measuring device is also disclosed.
Description
STOMA MEASURING DEVICE
Field of Invention The present invention relates to stoma measuring devices.
Background of the Invention Devices to measure stoma tract lengths are well-known. Exemplary of such devices are U.S. Patent Nos. 4,972,845; 5,356,382; and 5,343,874. One type of stoma that is measured is that which extends from the abdominal wall into the stomach.
Gastrostomic feeding devices placed into this type of stoma provide nourishment to patients unable to otherwise ingest food due to the effects of a stroke, coma, serious injury or other medical problem. The preferred method for the placement of gastrostomic/enteral feeding devices is through a percutaneous endoscopic gastrostomy (PEG) which involves the non-invasive surgical creation of the stoma into the stomach thro^uglr.the abdominal wall using only a local anesthetic. Gastrostomic feeding devices such as enteral feeding tubes are generally used only for limited periods of time while low-profile gastrostomy devices are used in long-term or permanent installations.
Gastrostomy devices generally are not adjustable, but instead are manufactured in several lengths. The length of the stoma, or the distance between the interior wall of the body cavity and the patient's outer layer of skin, varies from person to person, such as between that of an adult and a child. Therefore, when choosing the appropriate gastrostomy device it is necessary to accurately measure the stoma length.
An object of this invention is to provide an improved stoma measuring device capable of being operated with a single hand.
An additional object of this invention is to provide a method of measuring stoma length by utilizing the stoma measuring device described herein.
Summary of the Invention The present invention relates to a stoma measuring device for determining the length of a stoma. The stoma measuring device comprises an inner shaft member, an outer tubular member, and an actuation means. The inner shaft member forms the central support of the stoma measuring device. The outer tubular member is attached to the inner shaft member and to the actuation means. The outer tubular member has scale indicia on

Inner shaft member 20 is comprised of thermoplastic polyurethane and is surrounded by outer tubular member 40. Distal end 42 of outer tubular member 40 is attached to distal end 24 of inner shaft member 20 by mold tipping. Actuation means 60 has a proximal end sleeve 64 into which proximal end 22 of inner shaft member 20 fits.

The actuation means is attached at a distal end to the outer tubular member and at a proximal end to the inner shaft member. In this manner the movement of the outer tubular member and the actuation means are interrelated. The actuation means causes the outer tubular member to move toward the distal end of the stoma measuring device. The actuation means may be characterized by a configuration such that, when operated, the outer tubular member is moved. Such a configuration of the actuation means may comprise a plurality of arms, such as a rounded, are, or bent shape connected at a distal and a proximal end. Preferably, the actuation means comprises two oppositely facing bent arms connected at a distal and a proximal end. The actuation means may be comprised of any material that will enable movement of the outer tubular member. Exemplary of materials suitable for use as the actuation means are polypropylene, polyvinyl chloride, polyurethane, or a silicone elastomer. Preferably, the actuation means is comprised of a thermoplastic polyurethane.

Exemplary of materials suitable for use as the measuring bar are polypropylene, polyvinyl chloride, polyurethane, or a silicone elastomer. Preferably, the measuring bar is comprised of a silicone elastomer.
In more detail Figures 1 and 2 describe a stoma measuring device 10 and utilization of the stoma measuring device 10. Referring to Figure 1, stoma measuring device 10 comprises an inner shaft member 20, an outer tubular member 40, and an actuation means 60. Inner shaft member 20 is attached to actuation means 60 at a proximal end 22 of inner shaft member 20. Outer tubular member 40 is attached to the inner shaft member 20 at distal end 42 of outer tubular member 40 and attached to actuation means 60 at proximal end 44 of outer tubular member 40. Inner shaft member 20 is comprised of thermoplastic polyurethane and is surrounded by outer tubular member 40. Distal end 42 of outer tubular member 40 is attached to distal end 24 of inner shaft member 20 by mold tipping. Actuation means 60 has a proximal end sleeve 64 into which proximal end 22 of inner shaft member 20 fits. Proximal end sleeve 64 of actuation means 60 and proximal end 22 of inner shaft member 20 are attached by solvent bonding.
The outer tubular member 40 further comprises an outwardly extensible distal section 50 which when extended provides means for engaging the stoma measuring device 10 with the inner wall of the internal body cavity. The outwardly extensible distal
5 section 50 is formed by a plurality of short longitudinal cuts 52. The outwardly extensible distal section 50 further comprises small holes or perforations 56 that weaken the distal section 50, thereby requiring less force to cause the outwardly extensible distal section 50 to extend outwardly from the inner shaft member 20. The outer tubular member further comprises scale indicia 54 on an exterior surface thereof. The zero point of the scale indicia 54 is a proximal edge 47 of engaging means 46. The scale, in millimeter increments, increases from proximal edge 47 toward the actuation means 60.
The actuation means 60 is attached at a distal end 62 to the proximal end 44 of outer tubular member 40 and at a proximal end 66 to the proximal end 22 of inner shaft member 20. In this manner the movement of the outer tubular member 40 and the actuation means 60 are interrelated. The actuation means 60 is comprised of two oppositely facing bent arms 68 connected at distal end 62 and proximal end 66 of actuation means 60. The actuation means 60 is comprised of a thermoplastic polyurethane.
Figure 2 illustrates utilization of a stoma measuring device 10. The stoma measuring device 10 enables the measurement of stoma length preferably in a one hand operation. The stoma measuring device 10 is shown inserted through stoma 80. A
distal end 42 of outer tubular member 40 is rounded to minimize potential tissue damage. When in operation actuation means 60 is actuated, for example by pressure, thereby causing an outer tubular member 40 to move toward a distal end 12 of stoma measuring device 10.
Since the outer tubular member 40 is attached to an inner shaft member 20 at distal end 42 extension of the outer tubular member 40 at outwardly extensible distal end section 50 occurs. The stoma measuring device 10 is retracted until engaging means 46 engage interior wall 82 of an internal body cavity such as the stomach. A measurement of stoma length is then taken using scale indicia 54. Once the measurement is taken, the distal section 50 is allowed to return to the nonextended position. The stoma measuring device 10 is then removed from the stoma 80.

Referring to Figure 3, stoma measuring device 10 comprises an inner shaft member 20, an outer tubular member 40, and an actuation means 60.
The actuation means 60 is attached at a distal end 62 to the proximal end 44 of outer tubular member 40 and at a proximal end 66 to the proximal end 22 of inner shaft member 20. In this manner the movement of the outer tubular member 40 and the actuation means 60 are interrelated. The actuation means 60 is comprised of two oppositely facing bent arms 68 connected at distal end 62 and proximal end 66 of actuation means 60. The actuation means 60 is comprised of a thermoplastic polyurethane.
Figure 2 illustrates utilization of a stoma measuring device 10. The stoma measuring device 10 enables the measurement of stoma length preferably in a one hand operation. The stoma measuring device 10 is shown inserted through stoma 80. A
distal end 42 of outer tubular member 40 is rounded to minimize potential tissue damage. When in operation actuation means 60 is actuated, for example by pressure, thereby causing an outer tubular member 40 to move toward a distal end 12 of stoma measuring device 10.
Since the outer tubular member 40 is attached to an inner shaft member 20 at distal end 42 extension of the outer tubular member 40 at outwardly extensible distal end section 50 occurs. The stoma measuring device 10 is retracted until engaging means 46 engage interior wall 82 of an internal body cavity such as the stomach. A measurement of stoma length is then taken using scale indicia 54. Once the measurement is taken, the distal section 50 is allowed to return to the nonextended position. The stoma measuring device 10 is then removed from the stoma 80.
Figures 3 and 4 describe a preferred embodiment of a stoma measuring device 10 and utilization of the stoma measuring device 10 wherein a measuring bar is utilized to measure stoma length. Referring to Figure 3, stoma measuring device 10 comprises an inner shaft member 20, an outer tubular member 40, and an actuation means 60.
6 Inner shaft member 20 is attached to actuation means 60 at a proximal end 22 of inner shaft member 20. Outer tubular member 40 is attached to the inner shaft member 20 at distal end 42 of outer tubular member 40 and attached to actuation means 60 at proximal end 44 of outer tubular member 40. Inner shaft member 20 is comprised of thermoplastic polyurethane and is surrounded by outer tubular member 40. Distal end 42 of outer tubular member 40 is attached to distal end 24 of inner shaft member 20 by mold tipping.
Actuation means 60 has a proximal end sleeve 64 into which proximal end 22 of inner shaft member 20 fits. Proximal end sleeve 64 of actuation means 60 and proximal end 22 of inner shaft member 20 are attached by solvent bonding.
The outer tubular member 40 further comprises an outwardly extensible distal section 50 which when extended provides means for engaging the stoma measuring device 10 with the inner wall of the internal body cavity. The outwardly extensible distal section 50 is formed by a plurality of short longitudinal cuts 52. The outwardly extensible distal section 50 further comprises small holes or perforations 56 that weaken the distal section 50, thereby requiring less force to cause the outwardly extensible distal section 50 to extend outwardly from the inner shaft member 20. The outer tubular member further comprises scale indicia 54 on an exterior surface thereof. The zero point of the scale indicia 54 is a proximal edge 47 of engaging means 46. The scale, in millimeter increments, increases from proximal edge 47 toward the actuation means 60.
The stoma measuring device 10 further comprises a measuring bar 90 surrounding outer tubular member 40. Measuring bar 90, moveable along the length of outer tubular member 40, is comprised of a silicone elastomer.
The actuation means 60 is attached at a distal end 62 to the proximal end 44 of outer tubular member 40 and at a proximal end 66 to the proximal end 22 of inner shaft member 20. In this manner the movement of the outer tubular member 40 and the actuation means 60 are interrelated. The actuation means 60 is comprised of two oppositely facing bent arms 68 connected at distal end 62 and proximal end 66 of actuation means 60. The actuation means 60 is comprised of a thermoplastic polyurethane.
Figure 4 illustrates utilization of a preferred embodiment of a stoma measuring device 10. The stoma measuring device 10 enables the measurement of stoma length preferably in a one hand operation. The stoma measuring device 10 is shown inserted through stoma 80. A distal end 42 of outer tubular member 40 is rounded to minimize potential tissue damage. When in operation actuation means 60 is actuated, for example by pressure, thereby causing an outer tubular member 40 to move toward a distal
Actuation means 60 has a proximal end sleeve 64 into which proximal end 22 of inner shaft member 20 fits. Proximal end sleeve 64 of actuation means 60 and proximal end 22 of inner shaft member 20 are attached by solvent bonding.
The outer tubular member 40 further comprises an outwardly extensible distal section 50 which when extended provides means for engaging the stoma measuring device 10 with the inner wall of the internal body cavity.

When in operation actuation means 60 is actuated, for example by pressure, thereby causing an outer tubular member 40 to move toward a distal
7 end 12 of stoma measuring device 10. Since the outer tubular member 40 is attached to an inner shaft member 20 at distal end 42 extension of the outer tubular member 40 at outwardly extensible distal end section 50 occurs. The stoma measuring device 10 is retracted until engaging means 46 engage interior wall 82 of an internal body cavity such as the stomach. Measuring bar 90 is moved by hand along the outer tubular member 40 until it is flush with abdominal wall 84. The distal section 50 is allowed to return to the nonextended position. The stoma measuring device 10 is then removed from the stoma 80. A measurement of stoma length is then taken by referencing the scale indicia 54 at distal end 92 of measuring bar 90.
