A thin tube used to move liquids from one place to another. See the Glossary article All about Catheters . An appliance is an ostomy device or system that must be adhered to the skin, and must collect the waste leaving the stoma. There are two general types of systems, non-adhesive systems and adhesive systems.
Some wafers have precut openings that fit well around the stomas.
Others have small openings that serve as a starting point to insert scissors and cut the opening to fit around the stoma. The wafer may be made of all one material, or may be a sticky inner ring and a tape-like outer flange. The adhesive systems have either a 1 piece or 2 piece design. 1 piece - The wafer comes with a waste collection bag already permanently attached. This system may have an open end for opening the bad and emptying the waste from time to time, or may have a closed end, which limits the time the wafer and attached bag can be worn.
