An ostomy pouching system or colostomy bag is a prosthetic medical device that provides a means for the collection of waste from a surgically diverted biological system (colon, ileum, bladder) and the creation of a stoma. Pouching systems are most commonly associated with colostomies, ileostomies, and urostomies.〔(【引用サイトリンク】title=Ostomy Information )〕 Pouching systems usually consist of a collection pouch plastic bag,〔(【引用サイトリンク】Mayo Clinic">title=Ostomy )〕 known as a one-piece system or, in some instances involves a mounting plate, commonly called a flange, wafer or a baseplate, and a collection pouch that is attached mechanically or with an adhesive in an airtight seal, known as a two-piece system. The selection of systems varies greatly between individuals and is often based on personal preference and lifestyle. Ostomy pouching systems collect waste that is output from a stoma. The pouching system allows the stoma to drain into a sealed collection pouch, while protecting the surrounding skin from contamination. Ostomy pouching systems are air- and water-tight and allow the wearer to lead an active lifestyle that can include all forms of sports and recreation. Ostomy pouching systems are also sometimes referred to as an appliance, where the term appliance refers to a prosthesis, as a mechanical replacement for a biological function. == Wafers/baseplates/flange == Most wafers/baseplates are manufactured using pectin or similar organic material and are available in a wide variety of sizes to accommodate a person's particular anatomy. The internal opening must be the correct size to accommodate the individual's stoma while protecting the skin from contact with waste. The methods for sizing this opening vary depending on the type of wafer/baseplate; some pre-cut sizes are available, some users customize the opening using scissors. Manufacturers have recently introduced moldable wafers than can be shaped by hand without the need for scissors.〔 Skin adhesion for modern wafers/baseplates/flanges are optimized on all the five parameters required in an adhesive: *absorption *tack and adhesion *flexibility *erosion resistance *ease of removal. In addition, modern wafers/baseplates/flanges with adhesive border can provide additional security that the system stays in place. Using a barrier film spray before applying a new flange will improve adhesion, soothe irritated skin and protect the skin from irritation. A wafer/baseplate/flange may last between one to many days before it needs to be replaced; this is highly dependent on the individual's lifestyle, ostomy type, and anatomy. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「ostomy pouching system」の詳細全文を読む スポンサード リンク
