Ostomy appliance having pressure applying member
View Patent ↗An ostomy appliance is described in the form of a controlled discharge device for controlling discharge from the stoma and/or an ostomy pouch for collecting discharged waste. The appliance may include one or more of: an elastomeric stoma seal for providing a seal around or directly against the stoma; a stoma occluder for occluding the stoma without passing internally into the stoma; a peristomal foam wall; a confinement seal for confining at least solid excreta to a confinement region adjacent to the stoma; a stowable collector bag; and interchangeable controlled discharge devices and ostomy pouches. The foam wall may provide a barrier to stool, but allow escape of flatus. The foam wall and/or the stoma occluder and/or the confinement seal may apply a force in a direction to increase the sealing force on the stoma seal.
1. An ostomy appliance comprising:
adhesive means secured to the ostomy appliance for removably adhering the ostomy appliance to an ostomate's skin, adhesive means including an adhesive member having an inner periphery and a stomal aperture;
sealing and protecting means for sealing the inner periphery of the adhesive member around the stomal aperture and protecting the adhesive member from contact by stomal discharge, said sealing and protecting means including a pressurizable elastometric sealing member having an outer surface facing away from the ostomate's skin; and
pressure producing and applying means for producing pressure from a source external to a stoma and applying said externally sourced pressure directly or indirectly to said outer surface of said pressurizable elastometric sealing member and urging said sealing member towards the skin, said producing and applying means including a cap on said adhesive member defining a space therebetween containing at least a portion of said pressure producing and applying means.
2. The ostomy appliance according to claim 1 , wherein the sealing member at least partly overlaps an edge of the adhesive member, to define an overlapped seal.
3. The ostomy appliance according to claim 1 , wherein the sealing member projects inwardly of the inner periphery of the adhesive member.
4. The ostomy appliance according to claim 3 , wherein the sealing member comprises a tissue contacting portion for contacting a portion of the ostomate's tissue.
5. The ostomy appliance according to claim 4 , wherein the tissue contacting portion comprises a peristomal skin contacting portion.
6. The ostomy appliance according to claim 5 , wherein the sealing member is configured not to contact the stoma.
7. The ostomy appliance according to claim 4 , wherein the tissue contacting portion comprises a stoma contacting portion.
8. The ostomy appliance according to claim 1 , wherein the pressure producing and applying means is configured to apply pressure directly or indirectly to the adhesive member.
9. The ostomy appliance according to claim 1 , wherein the pressure producing and applying means is configured to apply pressure directly or indirectly to a region of the sealing member projecting radially inward of the inner periphery of the adhesive member.
10. The ostomy appliance according to claim 1 , wherein the pressure producing and applying means comprises a resiliently compressible member.
11. The ostomy appliance according to claim 10 , wherein the pressure producing and applying means comprises resiliently compressible foam.
12. The ostomy appliance according to claim 1 , wherein the ostomy appliance includes a controlled discharge device.
13. The ostomy appliance according to claim 1 , wherein the ostomy appliance includes a collection pouch.
