Description

A medical care device for leg postoperative care

Technical field

The invention belongs to the technical field of medical care, and specifically discloses a medical care device for leg postoperative care.

Background technique

With the acceleration of the pace of life, there are more and more traffic vehicles, traffic accidents are increasing year by year, and there are more patients with leg injuries. Therefore, patients require surgical treatment of their legs, and they need to stay in bed for a long time after surgery, resulting in leg muscle atrophy. , thus requiring postoperative rehabilitation training for the patient’s legs;

In the past, medical care used health care devices after leg surgery. Because the patient's legs did not exercise for a long time, and over time, muscle atrophy was caused, which affected the patient's normal activities. For those who were bedridden for a long time, the connecting ligaments of the feet were inactive for a long time. , resulting in atrophy, which in turn causes the leg muscles to have low exercise intensity and poor mobility. At the same time, the caregiver needs to pull the patient's leg to perform stretching exercises. And because the patient has not exercised for a long time, the foot connecting ligaments have excessively atrophied, and the caregiver pulls the patient's legs. When the patient's legs are stretched, he cannot pay good attention to the extension range of the patient's legs, which may cause secondary damage to the patient's legs.
