Control device and method for elbow joint rehabilitation training equipment

Abstract

The invention discloses a control device and method for elbow joint rehabilitation training equipment. The device comprises a big arm supporting rack and an elbow joint bending and stretching mechanism arranged on the big arm supporting rack, the elbow joint bending and stretching mechanism comprises rocking bars with middles rotatably connected to the big arm supporting rack, a drive component and a driving device, gripping force sensors are arranged on the upper portions of the rocking bars and electrically connected with a controller, the controller is electrically connected with the driving device, the gripping force sensors detect gripping force values and transmit the gripping force values to the controller, and the driving device acts under the command of the controller according toset clockwise and antilockwise rotation and time and a set rate. The clockwise and anticlockwise rotation, time and rate of the elbow joint bending and stretching mechanism can be determined according to the gripping force and duration time of a patient, so that the using experience of the patient is effectively improved.

Description

technical field [0001] The invention relates to a control device for elbow joint rehabilitation training equipment, which belongs to the field of medical rehabilitation equipment. Background technique [0002] Elbow joint fractures or elbow joint stiffness are very common clinically. After an elbow joint fracture occurs, surgical treatment or fixed treatment is usually used. In order to ensure the healing effect of the fractured part, it is necessary to restrict the movement of the forearm and elbow joint for a long time , but this will lead to poor lymphatic and venous return around the elbow joint, resulting in fibrous adhesion. After a long period of adhesion, muscle atrophy will be caused, and finally the joint capsule tissue will degenerate, and the elbow joint function will lose its ability to move. Therefore, after joint injury, taking scientific and effective rehabilitation training as soon as possible is of great help to the patient's joint recovery. However, at pre...

[0002] Elbow joint fractures or elbow joint stiffness are very common clinically. After an elbow joint fracture occurs, surgical treatment or fixed treatment is usually used. In order to ensure the healing effect of the fractured part, it is necessary to restrict the movement of the forearm and elbow joint for a long time , but this will lead to poor lymphatic and venous return around the elbow joint, resulting in fibrous adhesion. After a long period of adhesion, muscle atrophy will be caused, and finally the joint capsule tissue will degenerate, and the elbow joint function will lose its ability to move.

Therefore, after joint injury, taking scientific and effective rehabilitation training as soon as possible is of great help to the patient's joint recovery. However, at present, the exercise of elbow joint extension and flexion mainly depends on the patient's own activities. However, due to the pain in the postoperative lesion and the Exercise will also bring a lot of discomfort, which will affect the recovery of the patient's elbow joint extension and flexion function, and further affect the patient's work and life.

For this reason, the applicant has developed an elbow joint flexion and extension mechanism that can be extended and bent on the big arm support frame, but this mechanism cannot easily adjust its action during exercise, and further research and improvement are needed
