Stoma irrigation system

Claim 1

A stoma irrigation device for use with a plastic drain sleeve of tubular configuration, whereby a colostomy patient is enabled to use said sleeve in the cone or combination cone-and-catheter irrigation methods under closed system condition, said device comprising a coupling unit comprising a pair of axially interengageable annular members adapted to be axially slidably interfitted, one within the other from opposite sides of a plastic drain sleeve to encompass a section of the sleeve wall and form a fluid-tight seal about said wall section, one of said annular members being formed with attachment means for coupling a closure member thereto in fluid-tight relation, said annular members including complementary frictional interference elements which are engaged in the fully axially interfitted position of said members to frictionally retain them in such position and also to maintain said seal with the wall of said plastic sleeve; and a closure member adapted to mate with said one annular member and detachably engage said attachment means to form a fluid-tight joint with said annular member after the encompassed section of plastic sleeve wall has been cut away, said closure member comprising a cone which is formed in its apical region to be received in said inner annular coupling member and to project inwardly beyond the inner end of said coupling member, said cone having at its base attachment means for detachably engaging said engagement means of said coupling to cause said apical region to protrude internally of the inner face of said coupling, said cone being formed with a passage extending axially therethrough and being formed with a tube for connection to a source of irrigating fluid.
