The unit consists of a casting molded from a real forearm from the wrist to just below the elbow. New Life/form®soft vinyl skin provides realistic feel and appearance to ensure a realistic training experience. The arm features eight sites for practicing intracutaneous injections. If fluid is properly injected, a characteristic skin welt will form. The welt is removed by withdrawing the fluid after practice. Each site is reusable by dozens of students. Includes arm section with eight injection sites, 2 oz. bottle of liquid skin repair, syringe, teaching guide, and storage box. The included liquid skin repair (LF01009U) will extend the life of skin; however, skin is not replaceable and the simulator will eventually need replacement. Five-year warranty. Size: 13″ x 11″ x 5″. Medium and Dark skin colours available.
