Abstract
Abstract An ileostomy pouch and mounting device for the pouch are disclosed. The pouch comprises a bag having a drain opening at one end and a stoma-receiving opening adjacent its other end. An O-ring is sealed to the periphery of the stoma-receiving opening and has an integrally molded skirt flaring radially from the O-ring. A mounting ring is provided for the pouch and has an annular body-engaging face and an annular peripheral groove extending radially inwardly toward the axis of the ring. The O-ring is received in the groove entirely around the mounting ring to securely fasten the bag to the mounting ring.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
167 words
An ileostomy pouch comprising a bag of elastic sheet material having a drain opening in one end and a stoma-receiving opening adjacent its other end, and an O-ring of stretchable elastic material having an integrally molded skirt flaring radially outwardly therefrom, a portion of said skirt being sealed on the bag to the periphery of said stoma-receiving opening, said O-ring having a circular cross section, the molded skirt having a generally flat configuration lying in a generally radial plane and having a thickness substantially less than the diametral thickness of the O-ring cross section, the radial extent of the skirt beyond the portion thereof sealed to the bag being free of the bag and of sufficient size to be grasped by the user to aid in installing the bag by stretching the O-ring over an annular flange of a mounting ring to position the O-ring radially in a groove of the mounting ring associated with the annular flange to thereby lock the bag on the mounting ring.
Claim 2
Dependent Claim
167 words
An ileostomy pouch comprising a bag of elastic sheet material having a drain opening in one end and a stoma-receiving opening adjacent its other end, and an O-ring of stretchable elastic material having an integrally molded skirt flaring radially outwardly therefrom, a portion of said skirt being sealed on the bag to the periphery of said stoma-receiving opening, said O-ring having a circular cross section, the molded skirt having a generally flat configuration lying in a generally radial plane and having a thickness substantially less than the diametral thickness of the O-ring cross section, the radial extent of the skirt beyond the portion thereof sealed to the bag being free of the bag and of sufficient size to be grasped by the user to aid in installing the bag by stretching the O-ring over an annular flange of a mounting ring to position the O-ring radially in a groove of the mounting ring associated with the annular flange to thereby lock the bag on the mounting ring.
Claim 3
Dependent Claim
179 words
An ileostomy pouch comprising a bag of elastic sheet material having a drain opening in one end and a stoma-receiving opening adjacent its other end, a mounting ring for said pouch having an annular body-engaging face, an annular peripheral groove in said ring extending radially inwardly toward the axis of the ring, and an O-ring of stretchable elastic material having an integrally molded skirt flaring radially outwardly therefrom, a portion of said skirt being sealed on the bag to the periphery of said stoma-receiving opening, said O-ring having a circular cross section, the molded skirt having a thickness substantially less than the thickness of the O-ring cross section, the radial extent of the skirt beyond the portion thereof sealed to the bag being free of the bag and sufficient in size to be grasped by the user to aid in installing the bag by stretching the O-ring over the mounting ring for positioning radially into said peripheral groove, said O-ring being received in said groove entirely around said mounting ring and thereby locking the bag to the mounting ring.
Claim 4
Dependent Claim
