Ostomy bag
First Claim
1. An ostomy appliance having an ostomy bag provided with a stoma encircling opening adjacent one end of one side thereof, a coupling member having a portion secured to said one end of said ostomy bag around said bag opening, said portion extending outwardly from said side of said ostomy bag, said portion having a passage extending between the free end of said coupling member and its end contiguous to said ostomy bag providing an opening of substantially the same size as said ostomy bag opening whereby a stoma may extend into said passage and said ostomy bag, said portion having an uninterrupted surface exposed to said passage and to the interior of said ostomy bag whereby the accumulation of soil on and around said coupling is minimized, said portion having a first engaging element formed thereon dimensioned to engage securely with a second engaging element on a coupling member secured to the body.

Abstract
A system is provided by which an ostomy bag can be securely coupled to an adhesive dressing that fits around the stoma and yet will permit the bag to be removed without disturbing the dressing. This system involves a first coupling member bonded to the dressing and a second coupling member bonded to the ostomy bag around the stomal opening. One coupling member consists of an upstanding rib or other projection which is dimensioned to sealingly engage an opening in the other coupling member.

- 1. An ostomy appliance having an ostomy bag provided with a stoma encircling opening adjacent one end of one side thereof, a coupling member having a portion secured to said one end of said ostomy bag around said bag opening, said portion extending outwardly from said side of said ostomy bag, said portion having a passage extending between the free end of said coupling member and its end contiguous to said ostomy bag providing an opening of substantially the same size as said ostomy bag opening whereby a stoma may extend into said passage and said ostomy bag, said portion having an uninterrupted surface exposed to said passage and to the interior of said ostomy bag whereby the accumulation of soil on and around said coupling is minimized, said portion having a first engaging element formed thereon dimensioned to engage securely with a second engaging element on a coupling member secured to the body.
- 9. An ostomy appliance comprising a pad or dressing having a generally circular aperture for passage of the stoma, said pad or dressing aperture encircled by a coupling member and an ostomy bag also having a generally circular aperture for passage of the stoma, said bag aperture encircled by a second coupling member, one of said coupling members being two opposed walls of closed loop annular channel form and the other coupling member of closed loop form having a rib or projection dimensioned to be gripped between the mutually opposed channel walls when said coupling members are connected, said rib or projecton having a thin resilient deflectible seal strip extending therefrom, which, when said rib or projection is disposed between said walls, springs away therefrom to sealingly engage one of said walls, and in which each coupling member is formed of resilient synthetic plastics materials.
- 24. An ostomy appliance comprising a pad or dressing having a generally circular aperture for passage of the stoma, said pad or dressing aperture encircled by a coupling member and an ostomy bag also having a generally circular aperture for passage of the stoma, said bag aperture encircled by a second coupling member, one of said coupling members being two opposed walls of closed looped annular channel form and the other coupling member having a rib or projection dimensioned to be gripped between the mutually opposed channel walls when said coupling members are connected, one of said walls having a thin resilient deflectible seal strip extending therefrom which, when said rib or projection is inserted between said walls, springs outwardly to engage said rib or projection, and in which each coupling member is formed of resilient synthetic plastics material.
- 27. An ostomy appliance comprising a pad or dressing having a body contacting surface and an outer surface with an aperture for passage of the stoma extending through said pad or dressing, a coupling member extending outwardly from said pad or dressing and encircling the intersection of said aperture and the outer surface of said pad or dressing and an ostomy bag also having an aperture in one bag wall for passage of the stoma with a second coupling member affixed to said bag wall around the periphery of said bag wall aperture and extending outwardly from said bag wall, said bag coupling member being two opposed walls of closed loop channel form and said pad or dressing coupling member being a closed loop form having a rib or projection dimensioned to be gripped between the opposed channel walls when said coupling members are connected, and a thin resilient seal strip extending at an angle radially inward from an inner surface of said rib or projection which engages the outer surface of said inner channel wall and wherein said rib or projection has a peripheral bead extending therefrom in a direction opposite said deflectible seal strip and said outer channel wall has a complementary bead on its inner surface, each of said two beads having an annular surface inclined to the common axis of said coupling members when connected, the arrangement being such that said two annular surfaces are in face-to-face contact when said two members are in their mutually coupled positions.
