Abstract
A model of a human abdominal wall for use in demonstrating or practicing the use and maintenance of percutaneous endoscopic gastrostomy tubes. The model includes two or more layers bound together, the top or "external" layer approximating the feel and texture of human skin. The second layer approximates the feel and resistance of the subcutaneous tissues in the human abdominal wall. A third layer may be added, approximating the feel and resistance of human stomach tissue. Openings are provided which pass completely through the model to accommodate placement of percutaneous endoscopic gastrostomy tubes.
