Abstract
An ostomy appliance comprising an adaptor having a distal end adapted to be coupled to an ostomy wafer and a proximal end adapted to be coupled to a cap, said distal end having an opening in fluid communication with an opening in said proximal end.
Claims26
An ostomy appliance comprising an ostomy cap configured for coupling to an ostomy wafer surrounding a stoma of a user, the ostomy cap comprising:
- a cap housing having a proximal end and a distal end with a cavity therein, said distal end configured for coupling via an attachment mechanism integrally formed with the cap housing to an attachment element of said ostomy wafer, said distal end comprising a first opening in fluid communication with a second opening in said proximal end;
- a sealing element surrounding the stoma, when said ostomy appliance is coupled to said ostomy wafer, and configured for sealing interior to said attachment mechanism of said cap housing and said attachment element of said ostomy wafer between said cap housing and said ostomy wafer, said sealing element accommodated within said cavity of said cap housing;
- a lid removably attached to said proximal end of said cap housing;
- and
- a collapsed pouch in fluid communication with said second opening in said proximal end, wherein said collapsed pouch is restrained by said lid of said cap housing, and wherein said collapsed pouch is deployable into a waste collection mode through the removal of said lid, said removal actuatable manually and automatically by the pressure buildup inside said ostomy appliance.

A method of using an ostomy appliance attached to an ostomy wafer surrounding a stoma of a user, wherein said ostomy appliance comprises an ostomy cap configured for coupling to an ostomy wafer, the ostomy cap comprising:
- a cap housing having a proximal end and a distal end with a cavity therein, said distal end configured for coupling via an attachment mechanism integrally formed with the cap housing to an attachment element of said ostomy wafer, and said distal end comprising a first opening in fluid communication with a second opening in said proximal end;
- a sealing element having an annular shape and configured for sealing interior to the attachment mechanism of said cap housing and said attachment element of said ostomy wafer between said cap housing and said ostomy wafer, said sealing element accommodated within said cavity of said cap housing;
- a lid removably attached to said proximal end of said cap housing;
- and
- a collapsed pouch in fluid communication with said second opening in said proximal end, wherein said collapsed pouch is restrained by said lid of said cap housing, wherein said collapsed pouch is deployable into a waste collection mode through the removal of said lid, said removal actuatable manually and automatically by the pressure buildup inside said ostomy appliance,
- said method comprising manually removing said lid to deploy said pouch into said waste collection mode to eliminate waste through said stoma.

An ostomy appliance comprising an ostomy cap configured for coupling to an ostomy wafer, the ostomy cap comprising:
- a cap housing having a proximal end and a distal end with a cavity therein, said distal end configured for coupling via an attachment mechanism integrally formed with the cap housing to an attachment element of said ostomy wafer through a snap-fit arrangement, said distal end comprising a first opening being in fluid communication with a second opening in said proximal end;
- an annular compressible foam sealing element accommodated within said cavity of said cap housing, wherein said sealing element is configured to surround a stoma and to seal an interface between said cap housing and said ostomy wafer, when said ostomy cap is coupled to said ostomy wafer, and wherein said sealing element is permeable to gas;
- a lid removably attached to said proximal end of said cap housing, said lid configured to bulge outwards or stiffen in response to a pressure from waste content or flatus gas inside said cap housing;
- a collapsed pouch in fluid communication with said second opening in said proximal end, wherein said collapsed pouch is restrained by said lid of said cap housing and disposed externally to said housing, wherein said collapsed pouch is deployable into a waste collection mode through the removal of said lid, wherein said removal is actuatable manually and automatically by the pressure buildup inside said ostomy appliance;
- and
- a gas flow path for releasing gases flowing from the stoma, wherein said cap housing comprises an opening fitted with a valve selectively openable by a user for releasing gas flowing from a stoma, and wherein said gas flow path passes through said opening fitted with said valve.
