A lower limb rehabilitation exercise device

Abstract

Disclosed is a lower limb rehabilitation therapeutic device. A lower limb protective frame comprises a thigh protective frame and a shank protective frame which are hinged through a bent joint. Thigh and shank inflation pressure belts are correspondingly and separately fixed to the thigh protective frame and the shank protective frame. In the corresponding protective frame direction, at least two air bags are arranged inside the inflation pressure belts; a sliding rheostat is arranged inside the bent joint, in the starting state, when the thigh protective frame and the shank protective frame are relatively bent along the bent joint to achieve the starting angle, the sliding rheostat changes the resistance, signals are sent out to an analog-digital converter through a time relay, and an inflation pump inflates the air bags inside the inflation pressure belts through an air pipe; when the thigh and shank protective frames return back to the vertical motion along the bent joint, gas inside the air bags are exhausted from an air valve. By adopting the reasonable control method, for the rehabilitation crowd bedridden for a long time and lack of exercise, the vein blood shunt running is improved, deep venous thrombosis is prevented from being formed, atrophic muscle is rehabilitated, anchylosis tractive force is lowered, and the rehabilitation exercise period is shortened.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a lower limb rehabilitation exercise device. Background technique [0002] Surgery is a relatively large stress stimulus. Usually, after surgery, the body will experience a series of confrontation reactions, enhanced inflammatory cell function, and increased platelet aggregation, which can easily lead to venous thrombosis. In addition, patients need to be restricted for a long time after surgery. In the hospital bed, during the long-term bed rest of the lower limbs, blood stasis can easily lead to the formation of blood clots in the patient's blood vessels, lack of activity can easily lead to muscle atrophy, and prolonged inactivity of the joints can easily lead to limited flexion and extension. [0003] During the recovery process of such patients, the main symptoms of treatment include but are not limited to improving venous blood flow stagnation, avoiding deep vein thr...

Problems solved by technology

[0002] Surgery is a relatively large stress stimulus. Usually, after surgery, the body will experience a series of confrontation reactions, enhanced inflammatory cell function, and increased platelet aggregation, which can easily lead to venous thrombosis. In addition, patients need to be restricted for a long time after surgery. In the hospital bed, during the long-term bed rest of the lower limbs, blood stasis can easily lead to the formation of blood clots in the patient's blood vessels, lack of activity can easily lead to muscle atrophy, and prolonged inactivity of the joints can easily lead to limited flexion and extension

[0003] During the recovery of such patients, the main symptoms of treatment include but are not limited to improving venous stagnation, avoiding deep vein thrombosis, rehabilitation of atrophied muscles, Reducing joint stiffness and stretching sensation, etc., requires a period of rehabilitation exercise, in which the patient's rehabilitation takes independent walking as the sign of staged rehabilitation, so the exercise content of the rehabilitation exercise period, especially the rehabilitation of the lower limbs, is the most important. The treatment of symptoms, in addition to improving the blood circulation of the lower extremities, avoiding the formation of deep vein blood, exercising muscles to improve muscle strength, increasing the amount of activity to improve joint flexibility, for patients who have been lying down for a long time and lack contact with the outside world, recovery is difficult. Controlling one's own state and maintaining an upright position is more likely to increase the patient's psychological burden, and even prolong the patient's recovery period due to psychological factors, which is not conducive to the patient's overall physical and mental recovery
