ostomy pouching system

An Ostomy Pouching System (also colloquially, and incorrectly called a Colostomy Bag) is a medical prosthetic that provides a means for the collection of waste from a diverted biological system (Colon, ileum, urinary); pouching systems are most commonly associated with colostomies, ileostomies, and urostomies. Pouching systems usually consist of a mounting plate, commonly called a wafer  and a collection pouch which is mechanically attached in a method that creates an airtight seal. Ostomy Pouching Systems are used to collect waste that is output from a stoma, the pouching system is attached to allow the stoma to drain into a sealed collection pouch, while also protecting the surrounding skin from contamination. Pouching systems come in one, and two piece designs; two piece designs allow the changing and use of multiple pouches while retaining the wafer for several days. The selection of systems varies greatly between individuals, and is often based on personal preference and lifestyle.
