ABSTRACT:
The ostomy pouch has a coupling or securement member formed as a washer-shaped wafer of adhesive material, preferably a hydrocolloid. The pouch is secured directly onto the abdominal wall with the adhesive wafer aligned with the stoma. Flushability of the pouch is enhanced by forming the pouch with converging side walls within an optimum angular range and a predetermined pouch width and pouch height. The pouch also has a predetermined wall thickness and the wafer is of predetermined thickness. Thus when the pouch is deposited in a water-saver toilet, bottom end first in a carrier sleeve, the pouch can flow in streamlined fashion through the passages of a toilet and any sewer pipe or septic line connected to the toilet. If the flush capacity of the toilet and the flow rate of water through the toilet and sewer line are increased, the ostomy pouch can be deposited in the toilet without a carrier sleeve.
