Abstract
A skin model for use in demonstrating or practicing intradermal injection of fluids is disclosed. The model is a composite laminate of: (1) a subcutaneous tissue-simulating layer made of a foamed elastomer of low compression deflection and hardness; (2) a dermis-simulating layer of about 1 to 3 mm thick of that is substantially nonporous has a slightly greater hardness than the subcutaneous tissue-simulating layer and a penetration value in the range of 30 to 100 mm and is made of a silicone elastomer that contains reinforcing fibers, and, optionally, flesh tone pigment; and (3) in epidermis-simulating layer about 0.1 to 1 mm thick made of a high tear strength, high tensile strength elastomer. One or more of the layers may be contoured so that the surface of the model is shaped to simulate contour defects in natural skin.
