Abstract

A feces control device includes a tubular member in which an inflatable balloon is positioned on one interior sidewall for closing the passageway to movement of feces when the balloon is expanded and allowing flow when the balloon is contracted against the sidewall to which it is attached. A second balloon on the inner end of the tubular member when inflated presses against the inner end of an umbrella mounted on the inner end of the tubular member thereby expanding the umbrella to a radially outwardly and forwardly extending sealing position in the stoma or rectum. When the umbrella balloon is deflated, the umbrella memory causes it to collapse to a position coaxial with the tubular member. Inflation passageways in the sidewall of the tubular member may include tube portions for inflating the balloons or removing the device from the rectum.

16. The feces control device of claim 15 and an umbrella balloon is positioned on the inner end of said umbrella around the inner end of said tubular member for operation between inflated and deflated conditions, said umbrella balloon when inflated pressing against the inner end of said umbrella holder for moving said umbrella to said expanded open shape.

17. The feces control device of claim 16 wherein said umbrella balloon is positioned on said umbrella inner end opposite said tubular member.

18. The feces control device of claim 17 wherein said umbrella when in its expanded open shape extends radially outwardly and forwardly from the inner end of said tubular member.

19. The feces control device of claim 18 wherein said tubular member sidewall includes an inflation conduit extending between said umbrella balloon and said outer end of said tubular member.

21. The feces control device of claim 18 and an inflation conduit extends between said balloon valve and said outer end of said tubular member, and inflation tube end pieces are connected to said balloon valve conduit and to said umbrella balloon conduit for connection to inflation means and for removal of said device from the rectum.

20. A feces control device comprising,

a tubular member having inner and outer ends interconnected by a passageway, said tubular member having a sidewall with inner and outer faces, said passageway being defined by said inner sidewall face,

an inflatable balloon valve positioned in said passageway for selectively allowing passage of fecal material therethrough, and
