Ostomy appliance with integral closure
First Claim
1. An ostomy appliance that collects excreted human body waste, comprising:
- a wafer having a stoma opening through which the excreted human body waste passes;
an ostomy pouch having first and second wall panels connected along a top edge and both side edges of the ostomy pouch to form a storage area therebetween, the first wall panel having an opening that communicates with the stoma opening, wherein the excreted human body waste passing through the stoma opening of the wafer is stored in the storage area, the first and second wall panels form a bottom opening at a bottom edge of the ostomy pouch through which the human body waste is disposed; and
a closure integral with the bottom opening of the ostomy pouch and including a first portion of the first wall panel at the bottom opening of the ostomy pouch and a second portion of the second wall panel at the bottom opening of the ostomy pouch, wherein the first and second portions of the integral closure matingly engage each other to form an air-tight, odor-free seal that encloses the ostomy pouch with the human body waste being stored in the storage area, wherein the first and second portions are formed from a first material different and more rigid than a second material from which the first and second wall panels are formed, wherein the sealed integral closure withstands a pressure applied to the integral closure by the human body waste stored in the storage area, wherein the first and second portions each include alternating and interlocking male projections and female slots.

Abstract
An ostomy pouch for both one and two-piece ostomy appliances having an integral closure at the bottom of the pouch to allow the pouch to be emptied and re-sealed without the use of a separate closure. The integral closure has mating parts that are locked together and provides the ostomy appliance with a leak-proof, odor-proof seal when in a closed, sealed, and locked position. A slider, when the appliance is closed, can be moved along the integral closure, thereby separating the mated male and female parts to provide an opening through which the stored contents within the ostomy pouch can be emptied. After the stored contents have been emptied, the slider can reseal the pouch by rejoining the male and female parts. The integral closure is manufactured from material that is different and more rigid than the material used to manufacture the ostomy pouch.

17. An ostomy appliance that collects excreted human body waste, comprising:
-
a wafer having a stoma opening through which the excreted human body waste passes;
an ostomy pouch having first and second wall panels connected along a top edge and both side edges of the ostomy pouch to form a storage area therebetween, the first wall panel having an opening that communicates with the stoma opening, wherein the excreted human body waste passing through the stoma opening of the wafer is stored in the storage area, the first and second wall panels form a bottom opening at a bottom edge of the ostomy pouch through which the human body waste is disposed; and
a closure integral with the bottom opening of the ostomy pouch and including a first portion of the first wall panel at the bottom opening of the ostomy pouch and a second portion of the second wall panel at the bottom opening of the ostomy pouch, wherein the first and second portions of the integral closure matingly engage each other to form an air-tight, odor-free seal that encloses the ostomy pouch with the human body waste being stored in the storage area;
a slider that receives and substantially encompasses the first and second portions of the integral closure, wherein the slider comprises an internal cavity and first and second pinching members that form an opening through which the ostomy pouch is received and apply a pressure to the first and second wall panels to prevent the bottom opening from opening and unintentionally releasing the stored human body waste, wherein the first and second portions are formed from a first material different and more rigid than a second material from which the first and second wall panels are formed, wherein the sealed integral closure withstands a pressure applied to the integral closure by the human body waste stored in the storage area, wherein the first and second portions each include alternating and interlocking male projections and female slots. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
