METHOD FOR SIMULATION OF EXPLOSION TRAUMA OF SOFT TISSUE OF LIMB WITH FACTOR FRACTURE Russian patent published in 2021 - IPC A61B5/00 G09B23/28 

FIELD: experimental medicine.

SUBSTANCE: invention relates to medicine, namely to experimental medicine, military field surgery and traumatology, and can be used to simulate an explosive injury to the soft tissues of a limb with a fracture of the femur. Trauma is made to the previously trimmed surface of the thigh of a small laboratory animal under anesthesia - a rat. Trauma is inflicted by organizing an explosion by detonating an explosive charge, which is used as a pyrotechnic product for household use - an ordinary grating firecracker Korsar-2, which is installed in the rat's thigh in close proximity to the bone - at a distance of 0.5-0.8 cm from it , in a channel with a length of 2.0-2.5 cm, formed in the area of the location of the semitendinosus, semimembranosus and biceps muscles of the thigh, through a linear skin incision 0.8-1.0 cm long, made in the middle third of the lateral surface of the rat's thigh parallel to the longitudinal axis of the femoral bones, for which in a blunt way, with the help of a clamp, minimally traumatizing the tissues, pushing the skin and stratifying the muscles of the thigh. The Korsar-2 firecracker is installed in such a way that part of it protrudes 2 cm above the skin surface from the place of the fuse, and the remaining part is located in the formed channel and partially, namely 0.3-1.0 cm, protrudes from the counterperture on the opposite surface hips. To simulate an isolated explosive injury of the soft tissues of the limb with a fracture of the femur, rats weighing 320±30 g are used.

EFFECT: method provides possibility of simulating an explosive damage to the soft tissues of the thigh with a comminuted fracture of the femur in small laboratory animals (rats) by organizing an explosion by detonating explosive charges, which are used as ordinary grating firecrackers.
