Pneumatic upper limb rehabilitation robot

Abstract

The invention relates to the field of medical rehabilitation machinery, in particular to a pneumatic upper limb rehabilitation robot. Each upper limb training device is formed by connecting a first joint assembly, a second joint assembly, a third joint assembly, a fourth joint assembly and a fifth joint assembly in series, wherein the first joint assemblies, the second joint assemblies and the third joint assemblies are used for achieving movement of the shoulder joints of a user, the fourth joint assemblies are used for achieving movement of the elbow joints of the user, and the fifth joint assemblies are used for achieving movement of the wrist joints of the user. The bilateral ten-degree of freedom pneumatic upper limb rehabilitation robot can help patients to conduct rehabilitation training on the shoulder joints, elbow joints and wrist joints on both sides and serve as or replace a professional physician.

Description

technical field [0001] The invention relates to the field of medical rehabilitation machinery, in particular to a pneumatic upper limb rehabilitation robot. Background technique [0002] Stroke, commonly known as stroke, is a sudden onset of cerebrovascular disease and the most serious complication of cerebrovascular disease. Stroke is considered to be one of the three major diseases threatening human health. According to statistics, as many as 2 million people in China suffer from cerebral apoplexy every year, and there are still 7 million stroke patients, of which 4.5 million patients are hemiplegic or paralyzed, with varying degrees of loss of mobility of limbs, inability to take care of themselves, and disability rate up to 75%. The upper limbs of the human body bear very important responsibilities in daily life and complete various delicate and complex activities. Dysfunction of the upper limbs will seriously affect people's daily life. Therefore, the reconstruction ...

Problems solved by technology

In addition, this type of rehabilitation robot is usually only connected to the patient through the wrist, and its reaction force may cause damage to the patient's wrist or other parts of the patient's limb during rehabilitation.

Exoskeleton-type rehabilitation robots can be directly worn on the human body, and each degree of freedom is limited by the movement mode and size of human joints, so the mechanism is relatively complicated. Since each joint of this type of rehabilitation robot is attached to the human body, the weight and inertia of the robot and the patient's limbs Affects the drive characteristics and kinematics of the robot
