1. An ostomy appliance comprising:
- a bag having an opening for receiving material from a stoma,a thin, flexible membrane having a bag side and a skin side, the membrane having an inner portion connected to the bag circumscribing the opening and an outer portion which is adapted to be supported on the user'"'"'s skin with the bag side exposed to the air,adhesive means on the skin side of the membrane for attaching the membrane to the peristomal area of the user, said outer portion of said membrane with said adhesive means thereon adapted to transmit weight from the ostomy appliance to the skin of the user, anda cover sheet overlying the adhesive means on the skin side of the membrane, the cover sheet being removable to expose the underlying adhesive means for attachment of the membrane and the bag to the peristomal area,said membrane and adhesive layer having;
a combined thickness of less than about ten thousandths of an inch,a combined elasticity coefficient of less than about 1.6 pounds per inch at 20% elongation, anda combined water vapor permeability greater than about 300 grams per square meter per 24 hours at 40°
C. and 80% relative humidity.

Abstract
An ostomy appliance in which an ostomy bag is supported on the user'"'"'s skin by a membrane adhesively held on the skin where the membrane and adhesive layer are very thin, flexible, elastic and highly permeable to water vapor and oxygen tranmission. A stiffening member is removably provided for mounting the very thin, flexible membrane in a spread out condition while it is being attached to the skin, and the stiffening member is thereafter removed so that the appliance is supported on the skin only by the flexible permeable membrane.
