Abstract

An ostomy cartridge for use in host device in a mammal includes a body formed at elastomeric partially of polymeric material and a stem. The stem is secured to the body and is operable to permit insertion of the body into the host device and removal of the body from the host device. The stem and the body cooperate with one another and the host device to prevent flow of liquid and solid waste through the host device to the exterior of the mammal with which the host device is associated.

Claims

1. An ostomy cartridge for use with a host device associated with a mammal, said cartridge including:

a body formed at least partially of polymeric material; and

a stem secured to the body and operable to permit insertion of the body into the host device and removal of the body from the host device, said stem and said body cooperating with one another and associated with the host device to prevent flow of liquid and solid waste through the host device to the exterior of the mammal with which the host device is associated.

2. An ostomy cartridge as set forth in claim 1, wherein said stem and said body are adapted to provide at least one gas flow passage allowing gas to flow through the host device.

3. An ostomy cartridge as set forth in claim 1, wherein at least a portion of the body is adapted to absorb and retain liquid waste therein.

4. An ostomy cartridge as set forth in claim 1, wherein at least a portion of the body is adapted to absorb and retain liquid waste therein.

5. An ostomy cartridge as set forth in claim 1, including odor scrubber material carried by the body and operable to extract odor from the gas passing through the host device.

6. An ostomy cartridge as set forth in claim 1, wherein the body includes a fecal guard operable to selectively prevent flow of fecal material through the host.

7. An ostomy cartridge as set forth in claim 4, wherein the body includes a portion comprising polymeric foam.

8. An ostomy cartridge as set forth in claim 7, wherein at least a portion of the polymeric foam is open cell foam.

9. An ostomy cartridge as set forth in claim 7, wherein at least a portion of the polymeric foam is closed cell foam.

10. An ostomy cartridge as set forth in claim 1, wherein the body includes a fecal guard mounted on the stem and positioned inside of the patient proximal end of the body.

11. An ostomy cartridge as set forth in claim 10, and further comprising a tip mounted on the proximal end of the stem, the tip being adjacent the proximal side of the fecal guard, and having at least one gas flow first opening formed therethrough from a distal side to a proximal side of the tip.

12. An ostomy cartridge as set forth in claim 11, wherein the at least one gas flow first opening includes a slot.

13. An ostomy cartridge as set forth in claim 11, wherein the at least one first opening includes a through hole.

14. An ostomy cartridge as set forth in claim 10, wherein the stem includes an outwardly projecting ring and said fecal guard includes an internal groove adapted to receive the ring therein for mounting the fecal guard on the stem.

15. An ostomy device as set forth in claim 10, wherein the tip includes a dome-shaped patient proximal end.

16. An ostomy device as set forth in claim 7, wherein the foam material includes hydrophilic foam.

17. An ostomy device as set forth in claim 16, wherein the body has a proximal end impermeable to solid waste transfer therethrough.

18. An ostomy device as set forth in claim 1, including a hydrophobic membrane wrapped around at least a portion of the body.

19. An ostomy device as set forth in claim 1, wherein an exterior surface of the body is shaped to form gaps between the body and the host device to allow for movement of the host device.

20. An ostomy device as set forth in claim 19, wherein the exterior surface of the body includes a plurality of spaced-apart ribs that provide support for the host device.

21. An ostomy device as set forth in claim 19, wherein the exterior surface of the body includes at least one portion of a sphere.

22. An ostomy device as set forth in claim 19, wherein the exterior surface of the body includes a plurality of pleats.

23. An ostomy device as set forth in claim 1, wherein an exterior portion of the body is generally cylindrical.

24. An ostomy device as set forth in claim 1, wherein the stem has longitudinally extending elongate channels forming gas flow channels.
