Device for healing and training elbow joint

Abstract

The invention discloses an elbow joint rehabilitation training device, which is used for assisting the rehabilitation training of human elbow joint. The device includes an upper arm connecting rod, an upper arm support frame, a pneumatic muscle fixed frame, a pneumatic muscle, a two-way pull rod, an up and down transmission rod, a front and back transmission rod, an elbow transmission rotating shaft, a front arm support frame and a front arm connecting rod. The device is used for simulating the freedom of human elbow joint, which can provide larger working space during a rehabilitation training to lead the human elbow joint to get assistant training; the device adopts a wearable structure which is simple and light and can be worn on the body of the patient conveniently; the comfort property is good, and the device can directly act on the affected limb, therefore the training is well pointed and the effect is good; the device adopts pneumatic muscle drives, which has good flexibility and safety, and a dual-pneumatic muscle drive can achieve the purpose of active / passive movement coordination; the device can achieve the control of the force of the driven elbow joint movement and the scope of the movement by the control of the working pressure of the pneumatic muscle, so as to ensure the diversity and the effectiveness of the training.

Description

technical field [0001] The invention belongs to the technical field of auxiliary medical rehabilitation training equipment, and in particular relates to an elbow joint rehabilitation training device, which can directly act on the elbow joint of an affected limb, and can perform single joint rehabilitation training. technical background [0002] Stroke is a common and frequently-occurring disease among middle-aged and elderly people, and it is one of the three most harmful diseases to human beings in the world today. There are approximately 6.6 million stroke patients in my country every year. As countries around the world enter aging countries, the number of stroke patients is bound to increase. Hemiplegia ranks first among the numerous patient sequelae produced by apoplexy. Hemiplegia caused by stroke often has psychological and other impacts on the patient himself and his family. Society and families need to spend a lot of money to treat and care for these patients, resu...

Problems solved by technology

[0004] However, the disadvantages of this known flexible exoskeleton elbow joint based on pneumatic muscles are: 1. After it is worn, its joint position with the human body is fixed, so it cannot adapt to different groups of people; 3. The bending installation of pneumatic muscles is not conducive to accurate position control and force control; 4. The structure does not consider the characteristics of ergonomics, which may easily lead to rehabilitation accidents
