Terminal traction upper limb rehabilitation training device

Abstract

The invention discloses a terminal traction upper limb rehabilitation training device. In the rehabilitation training, the upper limb forearm and the hand of a patient are fixed on the arm support andthe handle of a robot, and the arm of the robot drives the upper limb terminal of the human body so as to drive the upper limb to finish various rehabilitation training modes in the horizontal planeand the sagittal plane of the human body. The device is jointly provided with two motors and a single-action air cylinder to realize driving, wherein a first joint motor drives the big arm to swing relative to a stand column, a second joint motor drives the forearm to swing relative to the big arm through transmission of a second synchronous belt, and the single-action air cylinder drives the terminal of the robot to carry out vertical linear movement. By the use of a servo closed-loop control system, the gesture, the movement range and the training strength of the upper limb of the human bodycan be accurately controlled. A controller consists of a touch screen and a switch button, wherein through the touch screen, a rehabilitation training mode can be selected, the training of each rehabilitation mode is displayed by a corresponding dynamic schematic diagram so as to be convenient and easy in understanding, and according to the situation of the patient, the speed and the time of eachrehabilitation training mode and the movement range of each joint can be regulated.

Description

technical field [0001] The invention relates to the technical field of medical and health care equipment, in particular to a terminal traction upper limb rehabilitation training device. Background technique [0002] Terminal traction upper limb rehabilitation training is a way of upper limb rehabilitation. It is very suitable for rehabilitation training of patients with loss of upper limb movement ability caused by upper limb brain nerve injury and muscle injury, such as stroke patients with hemiplegia. Most of them will lose part or all of one side of their body. Exercise ability. Due to lack of exercise or effective and scientific rehabilitation activities all year round, different degrees of muscle atrophy and joint adhesions occur in the limbs. Long-term lack of active and effective exercise training can easily lead to loss of mobility in the upper limbs. The upper limb rehabilitation training device can enable the upper limbs to be fully moved in the sitting position of...

Problems solved by technology

It is inconvenient to adjust the fit between the 6-DOF exoskeleton robot and the upper limbs of different patients, and the structure is complex. In addition, the upper limbs are fixed by wrapping. Once the robot fails or the patient's muscle spasms are likely to cause harm to the patient

In addition, there are terminal traction rehabilitation robots with 2 degrees of freedom Cartesian coordinates on the market, which can only realize the movement of the upper limbs in the horizontal plane. There are incomplete training of the upper limb joints, a single mode, and the upper limb ligaments cannot be stretched in all directions. Issues such as limited effects
