A parallel shoulder joint rehabilitation training machine

Abstract

A parallel type shoulder joint rehabilitation training machine comprises a shoulder seat (0), an upper arm seat (4), a crank (1), a first connecting rod (2), a second connecting rod (3) and a human body upper arm (5). The shoulder seat (0) is fixed with a human body shoulder with a binding belt in a binding mode. After the upper arm seat (4) is fixed with the human body upper arm (5) through a binding belt in a binding mode, the two ends of the crank (1) are respectively connected with the shoulder seat (0) and one end of the first connecting rod (2) through a first rotating pair (R1) and a second rotating pair (R2), and the other end of the first connecting rod (2) is connected with one end of an upper arm seat (4) through a third sphere pair (S3). The two ends of the second connecting rod (3) are respectively connected with the shoulder seat (0) and the upper arm seat (4) through a first sphere pair (S1) and a second sphere pair (S2). The first rotating pair (R1) and the first sphere pair (S1) on the shoulder seat (0) cannot coincide. The second sphere pair (S2) and the third sphere pair (S3) on the upper arm seat (4) cannot coincide. When the crank (1) is driven to rotate in a continuing mode, the human body upper arm (5) can generate three-dimensional rotating around a shoulder joint (O), and the purpose of rehabilitation training is achieved. The parallel type shoulder joint rehabilitation training machine is simple in structure, convenient to manufacture, mount and use, and capable of being used for shoulder joint rehabilitation and training.

Description

technical field [0001] The invention relates to a parallel shoulder joint rehabilitation training machine, in particular to provide a shoulder joint rehabilitation training device for people with upper limb motor dysfunction. Background technique [0002] In recent years, limb motor dysfunction has gradually become a common problem affecting the normal life of the elderly and disabled people. About 70% of patients have different degrees of upper limb motor dysfunction. The recovery of upper extremity motor function has a great impact on patients' daily life ability. The shoulder joint is the basis of the upper limb movement of the human body. Through the movement of the shoulder joint, a large range of upper limb movement can be realized. The rehabilitation of the movement function of the shoulder joint is a prerequisite for the rehabilitation of the movement function of the elbow, wrist and finger joints. At the same time, single-joint training is the basis of compound mov...

Problems solved by technology

In addition, the traditional rehabilitation training method is the manual operation of the rehabilitation therapist or the use of simple equipment to assist the patient in rehabilitation exercise. The training efficiency and training intensity of these methods are difficult to guarantee and cannot meet the requirements of patients.

[0003] Most of the existing domestic shoulder joint rehabilitation training devices are a kind of fitness equipment, which need to be fixed on the ground or a bracket. The overall structure is huge and suitable for healthy people or those with mild shoulder joint diseases. It is not obvious, and cannot satisfy the all-round exercise of the shoulder joint, as described in patent documents 201020265887.4, 201220253452.7, etc.
