Abstract: A kind of adjustable external fixation device for lower extremity is designed. The circuit is mainly composed of TEC1-00703 semiconductor refrigeration chip, HZC-30A pressure sensor, STC89C52RC single chip microcomputer and other electrical components. It can realize the timing intelligent temperature control and meet the local fixed-point refrigeration. The design of adjustable structure and the application of intelligent air cushion can satisfy the full fixation of lower limbs of different individuals. Its operation does not need much medical knowledge. It can solve the problem of emergency transportation and follow-up treatment of lower limb injury in ice and snow sports. It has a good application prospect and universality.
