Abstract

The present invention is an individual pressure barrier pouch that is used in conjunction with the assembly of either a one piece or a two piece ostomy appliance or as a pressure barrier pouch that can be preassembled and integrated into the assembly of a two piece ostomy appliance. In all three embodiments, body waste material/excretions from the patient'"'"'s stoma/fistula pass through the pressure barrier pouch to enter the ostomy pouch. When pressure is applied to the ostomy pouch, the excretions no longer have access to escape through the path of least resistance between the stoma and the wafer stoma clearance hole as they do with a conventional ostomy pouch. The only access to the path of least resistance with the present invention would have body excretions backing up through the pressure barrier pouch.

Claims

1. A contained ostomy appliance consisting of an improvement to an ostomy pouch for collecting body wastes/excretions and flagellant gas from a stoma/fistula comprising the integration of:

a pressure barrier pouch constructed with a minimum of a first proximal side layer and a first distal side layer wherein said first layers have a perimeter consisting of a top, sides and a bottom, with said first proximal side layer having a first stoma/fistula clearance opening large enough to clear said stoma/fistula, located toward said top of said first proximal side layer;

wherein said perimeters of said first layers are attached to each other around said perimeter except for said bottoms that are left unattached, whereby said body wastes/excretions and flagellant gas are allowed to pass into

an ostomy pouch constructed with a minimum of a second proximal side layer and a second distal side layer wherein said second layers have a perimeter with a top and bottom, with said second proximal side layer having a second stoma/fistula clearance opening large enough clear said stoma/fistula, located toward said top of said second proximal side layer, aligned with said first stoma/fistula clearance opening in said first proximal side layer of said pressure barrier pouch wherein the areas surrounding said first and second stoma/fistula clearance openings are attached to each other;

said perimeters of said second layers are attached to each other except at said bottom of ostomy pouch wherein sealable drain completes said attachment, whereby pressure to outside of said ostomy pouch is not transferred directly to said stoma/fistula clearance openings in said first and second proximal side layers and breaches to said contained ostomy appliance are dramatically reduced or eliminated in all but the case where both of said pouches are completely full.

2. A contained ostomy appliance consisting of an improvement to an ostomy pouch for collecting body wastes/excretions and flagellant gas from a stoma/fistula as in claim 1 wherein said ostomy appliance is a one piece appliance with an adhesive backed attachment wafer fixedly mounted to said ostomy pouch and pressure barrier pouch with a stoma/fistula clearance opening starter that aligns with stoma/fistula clearance openings in said second proximal side layer of said ostomy pouch and first proximal side layer of said pressure barrier pouch, wherein a stoma/fistula clearance opening though said wafer can be custom cut to clear the size of said stoma/fistula or purchased with predetermined stoma/fistula clearance diameter openings.

3. A contained ostomy appliance consisting of an improvement to an ostomy pouch for collecting body wastes/excretions and flagellant gas from a stoma/fistula as in claim 1, wherein said ostomy appliance is a two piece appliance with an adhesive backed attachment wafer that has an attachment flange that snaps into a mating attachment flange that is mounted to said first and second proximal side layers where stoma/fistula clearance openings in said attachment flanges align with said stoma/fistula clearance openings in first and second proximal side layers whereby body wastes/excretions and flagellant gases are collected in said pressure barrier pouch and allowed to escape out said unattached bottom of said pressure barrier pouch into said ostomy pouch.

4. A contained two piece ostomy appliance consisting of an improvement to an ostomy pouch for collecting body wastes/excretions and flagellant gas from a stoma/fistula as in claim 1 wherein said ostomy pouch is assembled around a pre-assembled pressure barrier pouch where said pouches each have their own concentrically mounted attachment flanges and mate with an adhesive backed attachment wafer with a dual acting attachment flange that allows snapping of said attachment flanges of said ostomy pouch and said pre-assembled pressure barrier pouch to said dual acting attachment flange on said adhesive backed attachment wafer, without breaking the seal of the adhesive to the patient'"'"'s skin.
