Stoma cap
First Claim
1. An ostomy appliance comprising a central elongated relative rigid tube having inner and outer end portions, a cap secured to the outer end portion of the tube and adopted to engage the users skin when said tube is inserted in a stoma and a flexible extendable and collapsible bellows mounted on the inner end portion of said tube for sealing the inside of the stoma when said appliance is inserted therein;
- said bellows having plastic memory and being selectively extendible from a collapsed bellows configuration to an extended configuration wherein its outermost dimension is less than that of the bellows configuration and permits insertion of the bellows in a stoma, whereupon the bellows returns to its collapsed position after insertion in the stoma, due to its plastic memory and seals the inside of the stoma.

Abstract
An ostomy appliance is disclosed for selectively sealing a stoma. The appliance includes a central elongated relatively rigid tube having inner and outer end portions. A cap is support to the outer end portion of the tube and is adapted to engage the users skin when the tube is inserted in a stoma. A flexible extendable and collapsible bellows is mounted on the inner end of the tube for sealing the inside of the stoma when the appliance is inserted therein. A flexible rod insertable through the cap and tube for engagement with the bellows extends the bellows to collapse it for insertion in the stoma.

- 2. An ostomy appliance comprising a central elongated relative rigid tube having inner and outer end portions, a cap secured to the outer end portion of the tube and adopted to engage the users skin when said tube is inserted in a stoma and a flexible extendable and collapsible bellows mounted on the inner end portion of said tube for sealing the inside of the stoma when said appliance is inserted therein, and removable means for extending said bellows to permit insertion of the bellows and tube in the stoma, said bellows returning to its collapsed position upon removal of said means thereby to seal the inside of the stoma.
- 8. An ostomy appliance comprising a generally cup shaped cap having a central opening formed therein and an integral elongated hollow tube having an internal bore communicating with said opening, said tube having an inner end and being dimensioned to be inserted in a stoma, a flexible bellows having plastic memory and opposed first and second ends, said bellows being secured at its first end to the inner end of the tube with its interior communicating with the interior of the tube and having an opening in its second end, said bellows being selectively extendable to reduce its outermost dimension to permit insertion of the bellows and tube in a stoma whereupon the bellows returns to its collapsed position due to its plastic memory and seals the inside of the stoma, and removable closure means for said cap opening.
