Abstract

An ostomy irrigation system and an ostomy port useful therewith permit independent, hands-free irrigation by a user having an ostomy or surgically created reservoir. The system includes a pump unit capable of providing monitored, controlled pulsations of fluid at a volume and force suitable for safe and convenient introduction into an ostomy of the user; and a reservoir in fluid communication with the pump unit, at least one irrigation connector set including a tube attachable to the pump unit, and a connector nozzle adapted for selectively releasable, substantially fluid tight interlocking connection with an ostomy port in the ostomy of the user so that the system is effectively closed. Controls are also provided for operating the pump unit such that a user of the system can, without the assistance of others, attach the at least one irrigation connector set to the ostomy port in the user'"'"'s ostomy and, then without further substantial use of the user'"'"'s hands to control the connector or tubing, introduce irrigation fluid into the ostomy in a controlled and convenient manner.

Claims

1. A port for temporary placement into an ostomy of a user, for use with an ostomy irrigation/drainage system, the port comprising:

an adjusting cone to permit selective sizing to accommodate the anatomy of a user, and an elongated substantially tubular body having a first end and a second end, the first end being selectively releasably interconnectable to a tube connector set of the system and the second end being insertable into a stoma, to thereby permit controlled fluid introduction to or removal from the ostomy of the user, and further wherein the adjusting cone interfaces with the elongated tubular body, such that the port is longitudinally adjustable, to thereby permit selective sizing to accommodate the anatomy and stoma size of a particular user.

2. The port of claim 1, and further comprising a selectively operable retention member connected to the second end of the port, to thereby maintain the port in normal operative position in the ostomy until the irrigation or drainage procedure is complete and the port is intentionally removed.

3. The port of claim 1, and further comprising a closure member connectable to the first end of the substantially tubular body, to thereby permit the user to selectively ambulate for a period of time after introduction of fluid to the ostomy without spillage of irrigation fluid from the ostomy.

4. The port of claim 1, and further wherein the port is connectable to the skin of a user by an adhesive on a proximal side of the face plate of the port.

5. The port of claim 1, and further comprising an anti-reflux valve disposed within the second end of the port, to thereby prevent unintentional flow of fluids out of the port.

6. The combination of an ostomy port and a drainage tube, wherein the ostomy port comprises an elongated substantially tubular body having a first end and a second end, the first end being selectively releasably interconnectable to the drainage tube, and the second end being insertable into a stoma, to thereby permit controlled fluid removal from the ostomy of the user;

wherein the drainage tube comprises a first end and a second end, the first end having a detent mechanism thereon which is suitably sized and shaped to permit interlocking, substantially leak-proof detenting engagement with the ostomy port and the second end which is insertable into a receptacle for matter drained from the ostomy; and

wherein the port is longitudinally adjustable, to thereby permit selective sizing to accommodate the anatomy and stoma size of a particular user.

9. The combination of claim 6, wherein the port further comprises a selectively operable retention member connected to the second end of the port, to thereby maintain the port in normal operative position in the ostomy until the irrigation or drainage procedure is complete and the port is intentionally removed.

10. The combination of claim 6, wherein the port further comprises a closure member connectable to the first end of the substantially tubular body, to thereby permit the user to selectively ambulate for a period of time after introduction of fluid to the ostomy without spillage of irrigation fluid from the ostomy.

11. The combination of claim 6, wherein the port is connectable to the skin of a user by an adhesive on a proximal side of the face plate of the port.

12. The combination of claim 6, wherein the port further comprises an anti-reflux valve disposed within the second end of the port, to thereby prevent unintentional flow of fluids out of the port.

7. The combination of an ostomy port and an ostomy bag, wherein the ostomy port comprises an elongated substantially tubular body having a first end and a second end, the first end being selectively releasably interconnectable with the ostomy bag and the second end being insertable into a stoma, to thereby permit controlled fluid removal from the ostomy of the user;

wherein the ostomy bag has an opening with a detent mechanism suitably shaped and sized to thereby permit substantially leak-proof, interlocking engagement with the ostomy port; and

wherein the port is longitudinally adjustable, to thereby permit selective sizing to accommodate the anatomy and stoma size of a particular user.

13. The combination of claim 7, wherein the port further comprises a selectively operable retention member connected to the second end of the port, to thereby maintain the port in normal operative position in the ostomy until the irrigation or drainage procedure is complete and the port is intentionally removed.

14. The combination of claim 7, wherein the port further comprises a closure member connectable to the first end of the substantially tubular body, to thereby permit the user to selectively ambulate for a period of time after introduction of fluid to the ostomy without spillage of irrigation fluid from the ostomy.

15. The combination of claim 7, wherein the port is connectable to the skin of a user by an adhesive on a proximal side of the face plate of the port.

16. The combination of claim 7, wherein the port further comprises an anti-reflux valve disposed within the second end of the port, to thereby prevent unintentional flow of fluids out of the port.

8. The combination of an ostomy port and a gravity bag, wherein the ostomy port comprises an elongated substantially tubular body having a first end and a second end, the first end being selectively releasably interconnectable with the gravity bag and the second end being insertable into a stoma, to thereby permit controlled fluid introduction in the ostomy of the user;

wherein the gravity bag is adapted for substantially leak-proof, detenting, interlocking engagement with the ostomy port; and

wherein the port is longitudinally adjustable, to thereby permit selective sizing to accommodate the anatomy and stoma size of a particular user.

17. The combination of claim 8, wherein the port further comprises a selectively operable retention member connected to the second end of the port, to thereby maintain the port in normal operative position in the ostomy until the irrigation or drainage procedure is complete and the port is intentionally removed.

18. The combination of claim 8, wherein the port further comprises a closure member connectable to the first end of the substantially tubular body, to thereby permit the user to selectively ambulate for a period of time after introduction of fluid to the ostomy without spillage of irrigation fluid from the ostomy.

19. The combination of claim 8, wherein the port is connectable to the skin of a user by an adhesive on a proximal side of the face plate of the port.

20. The combination of claim 8, wherein the port further comprises an anti-reflux valve disposed within the second end of the port, to thereby prevent unintentional flow of fluids out of the port.
