Description

Ankle exercise device for thrombus prevention Technical Field The invention relates to the technical field of thrombus prevention, in particular to an ankle exercise device for thrombus prevention. Background Deep Vein Thrombosis (DVT) is a common complication of long-term bedridden, post-operative and hypercoagulable patients, and its occurrence is closely related to slow blood flow in the lower extremities, vascular endothelial injury and hypercoagulable state. Studies show that the ankle joint can effectively promote venous return of lower limbs and reduce blood stasis through flexion and extension actions of the ankle joint, and the ankle joint is a key non-drug means for preventing DVT. In the prior art, most of them perform ankle exercises by providing a rotatable pedal with a damper, and the patient rotates the pedal. However, in the use process, the resistance is not convenient to adjust, and in the early stage of rehabilitation, the patient often gives up exercise due to pain or weakness, and the exercise effect is poor. Disclosure of Invention Accordingly, the present invention is directed to an ankle exercise device for thrombus prevention, which solves the problems of the prior art that the adjustment of the resistance is inconvenient, and the patient often gives up exercise due to pain or weakness at the early stage of rehabilitation, and the exercise effect is poor. The invention solves the technical problems by the following technical means: An ankle exercise device for thrombus prevention, comprising: the device comprises a base, wherein a first fixing belt for fixing the lower leg of a patient is arranged on the base; The pedal mechanism is fixedly provided with a hinge shaft along the width direction of the base, the bottom of the pedal mechanism is fixedly provided with a driving plate, the upper end part of the driving plate is rotatably arranged on the hinge shaft, and the pedal mechanism is provided with a second fixing belt for fixing the sole of a patient; The adjusting mechanism comprises a plate body, a first push plate and a second push plate, wherein the first push plate and the second push plate are fixedly arranged on the plate body, the plate body is slidably arranged on the base along the length direction of the base, the first push plate is positioned at one end of the plate body, which is far away from the first fixing belt, and the driving plate is positioned between the first push plate and the second push plate; The driving mechanism is fixedly arranged on the base, is in transmission connection with the second push plate and is used for driving the adjusting mechanism to move; And the damping mechanism is arranged between the driving plate and the second push plate and used for increasing the resistance of the pedal mechanism to the rotation in the direction away from the patient. Through setting up above-mentioned structure, on the one hand, control actuating mechanism removes adjustment mechanism, and adjustment mechanism can drive pedal mechanism rotation, makes the patient carry out passive exercise, on the other hand, when the patient independently takes exercise, control actuating mechanism removes adjustment mechanism, can change damping mechanism's damping size. Further, one end of the base, which is close to the first fixing belt, is fixedly provided with a cushion block, one end of the cushion block is abutted to the driving plate, and when the pedal mechanism is in a vertical state, the cushion block is used for preventing the pedal mechanism from rotating in a direction close to a patient.
