Low back and two arms traction rehabilitation machine

Abstract

The invention provides a traction rehabilitation machine for the waist, the back and the two arms. The machine can perform targeted traction on the waist, the back and the two arms of a patient, and thus rehabilitation therapy is carried out. The traction rehabilitation machine for the waist, the back and the two arms comprises a waist and back system and two arm systems. The waist and back system comprises a buttock substrate, a middle back plate, a shoulder substrate, a left motion mechanism and a right motion mechanism. The waist and back system can make the waist move from side to side with power supplied by an electric push rod and make the waist do front-and-back pitching motion with the power supplied by an air cylinder. The arm systems respectively comprise a shoulder unit, an elbow unit and a wrist unit. The shoulder units can make the upper arms swing and twist relative to the shoulders, the elbow units can make the forearms swing and twist relative to the upper arms, and the wrist units can make the wrists swing relative the forearms. The rehabilitation machine locates the key joints of the human body by the adoption of a round ring wrapping structure. The air cylinder and the electric push rod are combined as a power source, and good effects can be achieved on the supplying of linear motion modes and adjustability of the velocity and the force.

Description

technical field [0001] The invention relates to a medical rehabilitation equipment, in particular to a waist back and two-arm traction rehabilitation machine, which belongs to the technical field of electromechanical equipment. Background technique [0002] With the acceleration of people's life rhythm and the increase of work pressure, more and more people sit at the desk for a long time, and lack of exercise and rest, the probability of people suffering from joint diseases of the lower back, shoulders and arms is greatly increased . Many countries are developing various traction rehabilitation robots with easy operation, complete functions and high safety performance. As a kind of medical rehabilitation robot, this robot has attracted more and more attention from countries and regions such as Europe, the United States, and Japan. Now various foreign rehabilitation robots have entered the Chinese market, but they are expensive. However, existing domestic rehabilitation ro...

Problems solved by technology

The rehabilitation device uses a motor to directly drive the joints, and the drive is realized through gears, so there is a rotation error, and it is difficult for ordinary motors to meet the high-torque rotation in this application.

[0004] The invention patent with the application number 201110352097.9 provides a wearable exoskeleton upper limb rehabilitation robot. It uses a high-power motor, a harmonic reducer drive and a disc motor. Although the rotation error is small, the general motor cannot meet its accuracy and power requirements. , the use of a special motor will lead to high costs; and the rehabilitation machine has a complex structure, is not easy to maintain, and the replacement of each part is poor

[0005] The invention patent with application number 201110029533.9 provides a wearable exoskeleton rehabilitation robot. The rehabilitation machine adopts a binding connection method to realize the connection between the machine and the human body, which has poor comfort and limited range of human activities.
