Adjustable leg and foot motion device of recovery machine

Abstract

The invention discloses an adjustable leg and foot motion device of a recovery machine. The adjustable leg and foot motion device comprises a supporting bottom plate, a shell is fixed to the supporting bottom plate, and a transmission mechanism is arranged in the shell. A transmission shaft penetrating through the center of the transmission mechanism is fixedly connected with cranks at the two ends of the transmission shaft, the cranks are rotationally connected with pedal devices, an angle adjusting frame penetrates through the middle of the shell and is hinged to the transmission shaft through a connecting rod, the pedal devices are in sliding connection with the angle adjusting frame, and an adjusting screw penetrating through the angle adjusting frame is arranged at the bottom of the supporting bottom plate. Adjusting supports and pedal mounting seats in the pedal devices are connected through ankle adjusting knobs, and the adjusting supports and pedals are connected through leg adjusting knobs. The leg and foot inclination angles and bending ranges of the adjustable leg and foot motion device can be flexibly adjusted, the adjustable leg and foot motion device is simple in structure, reasonable in design and convenient to use, multi-variable adjustability of legs and feet can meet the actual conditions and needs of different people, therefore, the individual high comfort degree is met, and the optimal recovery training effect can be achieved.

Description

technical field [0001] The invention relates to the technical field of rehabilitation medicine and sports fitness equipment, in particular to an adjustable leg and foot movement device of a rehabilitation machine. Background technique [0002] At present, due to the long-term bedridden and lack of exercise of patients with disabilities, chronic diseases, geriatric diseases and acute diseases in the recovery period, muscle function degeneration and muscle atrophy occur. The emergence of these situations has a lot to do with the lack of effective exercise. In order to prevent muscle function degeneration, muscle atrophy, and articular surface degeneration, the patient can do some active and passive rehabilitation training on the bed if the body allows it. Active and passive rehabilitation training can promote blood circulation, is the basic factor to maintain the physiological function of articular cartilage surface, and is an effective method to prevent muscle function degene...

AI Technical Summary

Problems solved by technology

However, the ankle inclination angle, leg bending range, and ankle bending range of the leg and foot movement devices of rehabilitation machines on the market cannot be adjusted, which cannot meet the needs of patients with multi-dimensional adjustability of legs and feet.

[0004] For example, for patients whose hip joints and thighs are not suitable for exercise after laparotomy, the leg and foot movement devices of traditional rehabilitation machines are like pedal bicycles, which require hip joint movement to drive thighs, calves, and ankles to cooperate with each other. The non-adjustability of the leg and foot movement device of the traditional rehabilitation machine cannot meet the needs of the patient's thigh without moving, only the calf and ankle cooperate with the movement
