Description

Orthopedic rehabilitation assistive device

Technical Field

The utility model belongs to the technical field of medical rehabilitation equipment, and specifically relates to an orthopedic rehabilitation auxiliary device.

Background Art

A walker is a common orthopedic rehabilitation assistive device, generally used by patients to support their body weight, maintain balance and assist walking. Existing walkers are usually divided into alternating walkers, lifting walkers, and wheeled walkers. They are generally used to reduce the load on the lower limbs. Patients with fractures that do not allow weight-bearing or with weak lower limb muscle strength and poor coordination can choose different walkers according to their own needs to maintain body balance and help rehabilitation.

The Chinese patent application number CN215081777U discloses an orthopedic rehabilitation auxiliary device, including a main support assembly, an intelligent brake assembly, a hand brake assembly, a seat plate and a wheel body. The main support assembly includes two relatively spaced tripods and a connecting rod for connecting the two tripods. The top of each tripod is provided with a hand grip; the bottom of the tripod is provided with a wheel body, and the wheel body includes an intelligent brake wheel body and a hand brake wheel body; the intelligent brake assembly is arranged on the main support assembly to brake the intelligent brake wheel body; the hand brake assembly is arranged on the main support assembly to brake the hand brake wheel body; the seat plate is rotatably arranged on the connecting rod; the two brake assemblies are used in conjunction with each other to improve the safety of patients during orthopedic rehabilitation. Although the device can achieve the braking effect through the intelligent brake assembly and the hand brake assembly in actual application, the hand brake assembly is installed at the bottom of the tripod, and the patient needs to bend down to operate during use, which is inconvenient. At the same time, the manufacturing cost of the intelligent brake assembly is high, so it is difficult to be both convenient and fast to operate and low in manufacturing cost, so there are great limitations.

In view of this, this application is hereby filed.
