[0038] Working principle: When in use, the fixing plate 1 is L-shaped, with a width of about 15 cm, a leg part of 50 cm, and a foot part of about 30 cm. The first airbag 2, the second airbag 5, and the third airbag 6 are all made of soft cloth materials. Under the action of the first connecting belt 311, the card slot 312, the buckle 313, and the second connecting belt 314, the first airbag 2 and the second airbag 5 are fixed to the top of the fixing plate 1, and the third airbag 6 is fixed to one side of the fixing plate 1. The patient's lower limbs are placed on the inner side of the first airbag 2 and the second airbag 5, and the foot is placed on the inner side of the third airbag 6. The nylon belt 322 is passed through the inner side of the positioning belt 321, and the nylon belt 322 is pulled. The hook belt 331 and the velvet belt 332 are controlled to stick according to the patient's leg circumference. Under the action of the three velvet belts 332 It is convenient to operate the leg binding and control the tightness as needed, which is more flexible and practical. The lower limbs and feet are fixed so that the foot and leg activity range is between ninety and one hundred and ten degrees, ensuring the functional position and preventing foot drop and thrombosis. The delivery tube 421 is inserted into the air inlet pipe 411 and the stability is improved by the nut 412. The three inflation tubes 7 are respectively connected to the intermittent inflation pump 10 through the three air outlet pipes 9. The intermittent inflation pump 10 is started. In the first two stages of inflation, the first airbag 2 and the second airbag 5 are alternately inflated and deflated. In the third stage of inflation, the first airbag 2 and the second airbag 5 are deflated, and the third airbag 6 is inflated. The inflation and deflation time is detected by the machine itself until the target pressure is reached. The gradient progressive pressure imitates normal human walking and effectively prevents thrombosis.
