Abstract

The coupling device for an ostomy pouch includes a flexible, deflectable, annular force transmitter member joined to an abdominal mounting plate that has a coupling member. The force transmitter member can be pulled in a direction away from the mounting plate during coupling of an ostomy pouch. The force transmitter member can thus oppose and neutralize a coupling force that is directed to the mounting plate and protect the abdomen from receiving the pressure due to the coupling force.

Claims

1. A coupling device comprising,

a) a flexible mounting plate having an opening for a stoma,

b) a coupling member having an annular base flange, said base flange including an annular rim projecting therefrom, said base flange having a lower surface and upper surface, said entire lower surface being joined to said mounting plate,

c) a flexible annular force transmitter member having an inside diameter portion and an outside diameter portion, said inside diameter portion being joined to said upper surface of said base flange around said annular rim, said outside diameter portion being freely deflectable toward and away from said mounting plate and being sized to permit annular gripping to transmit force through said force transmitter member to said annular rim.

2. The coupling device as claimed in claim 1 wherein said annular base flange is welded to said mounting plate.

3. The coupling device as claimed in claim 1 wherein said inside diameter portion of said force transmitter member is welded to said base flange.

4. The coupling device as claimed in claim 1 wherein said force transmitter member has a dished profile in cross-section such that said outside diameter portion projects away from said mounting plate.

5. The coupling device as claimed in claim 1 wherein said mounting plate has an outside periphery and the outside diameter portion of said force transmitter member is within the peripheral confines of said mounting plate.
