Our simulator includes the superficial structure of the abdomen, subcutaneous fat, fascia, preperitoneal fat, and peritoneum. The base is watertight and can be filled with fluid to simulate internal bleeding. It also includes two alligator clips to secure internal tissue structures such as a simulated intestine, which can be purchased separately (Part number: LGI-10). Additional replaceable tissues (LPMT-10) are sold separately.
