Description

A lower limb rehabilitation device for hemiplegic patients

technical field

The utility model belongs to the technical field of rehabilitation equipment, in particular to a lower limb rehabilitation device for hemiplegic patients.

Background technique

Elderly patients are prone to hemiplegia after stroke and other diseases. The disease makes one side of their limbs unable to move. Many elderly people choose to lie in bed or continue to sit and stand, and their limb muscles are prone to atrophy. Secondly, patients lack exercise after eating and are prone to Symptoms of bloating and indigestion that require light exercise to help digestion.

Such patients often need long-term recovery treatment after being treated in the hospital. One of the more convenient medical devices is the rehabilitation chair. Generally, the rehabilitation chair is equipped with equipment for exercising legs, which brings more benefits to the patient's rehabilitation treatment. Great convenience, the current rehabilitation chairs on the market are often complex in structure and expensive to manufacture. For most people, buying a rehabilitation chair is not a small burden. For example, patent CN107822847A discloses a multifunctional health care rehabilitation chair for sitting and standing motion, including a base plate, a fixed sleeve, a pull rod, a counterweight, a base, a first motor, a first rotating shaft, a backing plate, a second motor, a second rotating shaft, and a cam , gas cylinder, piston, spring, retaining net, air cushion, connecting trachea, bracket, and fixing plate are driven by various motors to drive patients to perform rehabilitation exercises.

The rehabilitation chair in the above technical solution is driven by a motor, and the cost of use is high. Specialized technicians are required for later maintenance and maintenance. It is suitable for use in hospitals or rehabilitation institutions, but not suitable for home use, and it is only suitable for families or patients with limited conditions. When it is necessary to perform simple training to recover, at this time, there is no need for so many functions, so it is very meaningful to invent a rehabilitation chair that is relatively simple to operate and can slightly increase the range of motion of the lower limbs to help patients recover or digest.
