Stoma plug
First Claim
1. An ostomy plug comprising:
- a. a first chamber for insertion into a stoma;
b. a second chamber in fluid communication with the first chamber to enable fluid from the second chamber to inflate the first chamber;
c. a flatus vent channel incorporated as an internal passage within at least one of the first or second chambers for venting flatus, wherein the first chamber is configured, when inflated, to (i) obstruct escape of solid and/or liquid body waste from the stoma; and
(ii} permit venting of flatus from the stoma at an interface between the first chamber and a wall of the stoma.

Abstract
An ostomy plug is described comprising first and second chambers having adjacent ends coupled to, and in fluid communication with, each other. The first chamber may be for insertion into a stoma. The second chamber may contain fluid for inflating the first chamber when the second chamber is squeezed or otherwise compressed. The plug may have a figure-of-eight configuration. The plug may be configured to permit venting of flatus while obstructing escape of other body waste from the stoma. The plug may incorporate an insertion aid for aiding insertion into a stoma. The plug may also incorporate a device for regulating the inflation pressure of the fluid to avoid undesirably high inflation pressures in the stoma.

22. An ostomy plug comprising:
-
a. a first chamber for insertion into a stoma; b. a second chamber in fluid communication with the first chamber to enable fluid from the second chamber to inflate the first chamber;
said first and second chambers having adjacent ends coupled to each other at a junction region;c. a flatus vent channel incorporated as an internal passage within at least one of the first or second chambers for venting flatus, wherein the first chamber is configured, when inflated, to (i) obstruct escape of solid and/or liquid body waste from the stoma; and
(ii} permit venting of flatus from the stoma; andd. valve means for controlling pressure in the first chamber, said valve means preventing fluid communication between the first and second chambers when the pressure in the first chamber reaches a specific value.
