[0031] like Figs. 1-2 As shown, a knee joint fixation brace and its usage method include a thigh fixation support 1 and a lower leg fixation support 2. Airbags 4 are adhesively attached to the inner walls of both the thigh fixation support 1 and the lower leg fixation support 2. The airbags 4 are connected to an external pressure pump via an air pipe 9. An air pressure valve 8 is provided on the air pipe 9, which can be an inflation / deflation connector or a threaded tightening connector. The thigh fixation support 1 and the lower leg fixation support 2 are connected together by a connecting assembly 3 to form a cylindrical structure. The connecting assembly 3 can use a Velcro structure for easy and quick installation and disassembly. An upper connecting rod 5 is provided on the outer wall of the thigh fixation support 1, and a lower connecting rod 6 is provided on the outer wall of the lower leg fixation support 2. The upper connecting rod 5 and the lower connecting rod 6 are connected together by a hinge assembly 7. The articulation component 7 can use an angle-adjustable chuck. Specifically, the angle is adjusted to 0° in the early stages of standing and walking, and then to 90° 2 weeks after surgery. This can effectively prevent excessive angle in the early stages from causing laxity of the reconstructed ligaments. Thereafter, the angle is increased by 10° every week, reaching 120° at 6 weeks. This can maintain the stability of the knee joint, facilitate the closure of the bone tunnel, and strengthen the stability of the reconstructed ligaments.

[0032] The airbag 4 is divided into airbag a, airbag b, airbag c, airbag d and airbag e. Airbag a and airbag b are located on the airbag 4 part of the thigh fixation support 1, and airbag c, airbag d and airbag e are located on the airbag 4 part of the calf fixation support 2.

[0033] The thigh fixed support 1 / calf fixed support 2 adopts carbon fiber material, through its "high strength-lightweight-high adaptability" characteristics, on the basis of realizing the core treatment target of "stable fixation-limiting abnormal activity", the wearing burden is minimized, the comfort is improved, and early rehabilitation training is supported, and finally the patient can recover the knee joint function faster.

[0034] A knee joint fixing brace using method,

[0035] Step one, the thigh fixed support 1 is put on the thigh, the calf fixed support 2 is put on the calf, and the connecting assembly 3 is fixed, at this time the air bag 4 is located at the position close to the thigh / calf;

[0036] Step two, the pressure pump is started, the air pressure valve 8 on the air bag five e is opened for inflation, and the remaining air pressure valves 8 are closed;

[0037] Step three, when the inflation air pressure of the air bag five e reaches the specified value, the air pressure valve 8 thereon is deflated, the air pressure valve 8 on the air bag four d is opened for inflation, and the remaining air pressure valves 8 are closed;

[0038] Step four, when the inflation air pressure of the air bag four d reaches the specified value, the air pressure valve 8 thereon is deflated, the air pressure valve 8 on the air bag three c is opened for inflation, and the remaining air pressure valves 8 are closed;

[0039] Step five, when the inflation air pressure of the air bag three c reaches the specified value, the air pressure valve 8 thereon is deflated, the air pressure valve 8 on the air bag two b is opened for inflation, and the remaining air pressure valves 8 are closed;

[0040] Step six, when the inflation air pressure of the air bag two b reaches the specified value, the air pressure valve 8 thereon is deflated, the air pressure valve 8 on the air bag one a is opened for inflation, and the remaining air pressure valves 8 are closed;

[0041] Step seven, when the inflation air pressure of the air bag one a reaches the specified value, the air pressure valve 8 thereon is deflated, and the remaining air pressure valves 8 are closed;

[0042] Step eight, after the air bag one a is deflated, the air pressure valve 8 thereon is closed;

[0043] The inflation and deflation are cycled according to the above steps, that is, the previous air bag starts to deflate, and the next air bag starts to inflate, and the pressure is added centripetally, (for example, the air bag inflation time is 45-60 seconds, and the deflation time is 15 seconds, the next air bag is inflated after the previous air bag is inflated for 45 seconds, and the subsequent air bags are added centripetally from the distal end to the proximal end of the lower limb), which produces a regular effect similar to muscle contraction and relaxation on the limb, promotes blood return and lymph circulation, helps to improve the blood supply of local tissues, promotes blood circulation, reduces edema, and reduces the risk of deep venous thrombosis of the lower extremity.

[0044] The total length of the cycle of inflation and deflation is 20-30 minutes, no more than twice a day.

[0045] The inflation amount of each air bag 4 is 40-70 mmHg, preferably comfortable for the patient, and this pressure is set mainly to improve blood circulation and prevent deep vein thrombosis of the lower limbs. If used for relieving lymphedema or postoperative detumescence, the inflation amount is 20-60 mmHg.

[0046] The inflation amount of each air bag 4 is <90 mmHg, avoiding compression of capillaries, affecting microcirculation, and causing subcutaneous hemorrhage.
