A 1-Piece system is one in which the wafer and pouch have been fused together during the manufacturing process. There are several different types of 1-Piece systems‰ۡÌÝÌ_such as drainable and closed‰ۡÌÝÌ_for the collection of stool. If the collection is for urine, a specific urinary appliance is indicated. The adhesive part of the system, which consists of a skin-friendly material known as hydrocolloid, can be either flat or convex, extended wear or
standard wear. The advantages of a 1-Piece system are: Only one piece to apply, Ease of application for those with dexterity limitations, Lower profile so less conspicuous, Greater comfort, as no flange, Costs less than 2-Piece system.
