Abstract

An open ended ostomy pouch having a folding bar attached to the bottom of the pouch. The folding bar extends on both sides beyond the width of the pouch at the bottom opening and includes interlocking closure components on opposite ends.

Claims

1. An ostomy appliance comprising a generally pear shaped pouch formed from two polymeric film surfaces permanently bonded along a majority of their length, each of said pouch polymeric film surfaces being a laminate of about 3 mils thickness of an outer and inner layer of ethylene vinyl acetate having a core of a copolymer of vinyl chloride and polyvinylidene chloride, one of said polymeric film surfaces being the skin side of said pouch and having an opening which fits around the stoma, the other polymeric film surface being the outer side of said pouch, a faceplate permanently bonded to the skin side of the pouch around said stomal opening, said faceplate having a centrally located opening which is expanded to fit the appliance snugly around the stoma and comprises a thin disk shaped film of polymeric material of from about 2 to 8 mils thickness having an adhesive composition which includes a pressure sensitive adhesive component and one or more hydrocolloids on its exposed surface and wherein the bond between said disk shaped film and said skin side of the pouch does not extend to the outer peripheral edge of said faceplate, said pouch including a narrow tail portion having an open bottom through which the contents of said pouch can be drained, and resealable bottom closure means comprising a semi-rigid folding bar of high density polyethylene of about 5 mils thickness permanently attached to the outer side of said pouch at the narrow tail portion near said bottom opening, said folding bar extending traversely across and beyond the width of said pouch tail portion and having interlocking closure elements on said extended portions of said folding bar wherein said interlocking closure elements are a section of male hook elements attached to the skin side of one extending portion of said folding bar and a section of female loop elements attached to the outer side of the other extended portion of said folding bar and wherein said bottom opening is sealed by rolling the tail portion of said pouch over said folding bar and bending the extended portions of said folding bar so that said male hook and female loop elements can be pressed together.

2. The appliance of claim 1 wherein said faceplate comprises a polyethylene film of about 2 mils thickness having as the adhesive composition from about 50 to about 150 mils of a homogeneous mixture on a weight percent basis of about 40% polyisobutylene, about 20% pectin, about 20% gelatin, and about 20% sodium carboxymethylcellulose.

3. The appliance of claim 2 wherein said skin side polymeric film surface is clear and said outer side polymeric film surface is opaque and said appliance includes a resealable opening across the top of said pouch above the stomal opening said top opening comprising interlocking surfaces on the inside of each of said polymeric film surfaces.

4. The appliance of claim 3 wherein said interlocking surfaces are a series of alternating raised ridges and grooves extending across the top of said pouch which are aligned so that by the exertion of a slight amount of pressure the raised ridge on the inside of one surface will fit within the groove on the inside of the other surface.
