Description

Portable elbow joint rehabilitation training device

Technical Field

The utility model relates to the field of rehabilitation medical instruments, in particular to a portable elbow joint rehabilitation training device.

Background

In the upper limb part of the human body, the elbow joint is a key part for connecting the big arm and the small arm and is divided into the lower part of the humeral head, the ulna and the upper part of the radius. According to investigation, in bone injury diseases of human bodies, the incidence rate of elbow joints is highest, the incidence rate of the elbow joints accounts for 14 percent of the incidence rate of bone injury, and when the elbow joints are dyskinesia, the probability of limited movement functions of the whole upper limbs can reach 70 percent or more. After elbow joint surgery, rehabilitation training is an important means for recovering and improving functions of the elbow joint, and can enable a patient to prevent loss of functions, improve the function recovery speed, improve or recover functions and maximize damaged individual functions through training.

At present, the rehabilitation training of the elbow joint is mostly completed by a professional doctor by means of professional rehabilitation training equipment, and the main purpose is to help the joint of a patient to recover normal movement function in a training mode, so that the muscle strength is recovered, and the patient can return to normal life. The training characteristics are as follows: long time and high frequency. The elbow joint specialized rehabilitation equipment in the current market mainly supports and pulls the upper limb by utilizing an electric generation and control mechanical power method to complete the flexion and extension actions between the large arm and the small arm so as to achieve the purpose of rehabilitation training.

The elbow joint rehabilitation training device commonly used at present adopts an electric control mode and comprises a relatively complex transmission structure. An elbow joint rehabilitation training device as mentioned in the application number CN113648187a, wherein the elbow joint rehabilitation training device can fix the big arm of a patient through the first support plate 1, the second support plate 201 fixes the small arm of the patient, a certain gap can be generated in the elbow joint of the patient by controlling the horizontal movement of the second support plate 201, then the sliding block 307 in the base 4 is controlled to move, and the angles of the first support plate 1 and the second support plate 201 are adjusted, so that the elbow joint training of the patient is effectively assisted.

The second support plate 201 is horizontally moved by driving the screw rod to rotate through the motor, so that the second support plate 201 horizontally moves through a nut fixedly connected with the second support plate and sleeved on the screw rod.

The sliding block 307 is connected with two sides of the rotating frame 208 through the connecting rod 304, two ends of the connecting rod 304 in the length direction are respectively hinged with the rotating frame 208 and the sliding block 307, so that the sliding block 307 moves in the horizontal direction to drive the rotating frame 208 to rotate, and the change of the included angle between the first supporting plate 1 and the second supporting plate 201 is adjusted. And the movement of the slider 307 in the horizontal direction is achieved by driving the second screw 302 by the second driving motor 301.

The slider 307 is fixedly connected with a second nut 303 sleeved on the second lead screw 302. The elbow joint rehabilitation training device is provided with a support guide rail 305 which is arranged in parallel with a second lead screw 302, and is provided with another second nut 303 sleeved on the support guide rail 305 and a connecting block 306 sleeved on the second nut 303, wherein the connecting block 306 is connected with a sliding block 307, so that when a second driving motor 301 rotates, the connecting block 306 and the sliding block 307 are mutually limited, and the sliding block 307 cannot rotate around the second lead screw 302 and only can horizontally move.

From the foregoing, the elbow joint rehabilitation training device in the present stage is set to an electric control mode, and the motor or other power mechanism drives the relatively complex transmission structure to realize the flexion and extension actions between the large arm and the small arm, so that the overall structure of the elbow joint rehabilitation training device tending to automation is relatively large. On the one hand, these devices are too expensive to be suitable for the purchase of the patient, and the use of the device by institutions also requires the cost of the device to be amortized by increasing the charge of a single treatment, resulting in an increase in the economic pressure of the patient; on the other hand, because the equipment adopts an automatic control mode, a specialized operation mode is needed to be matched, so that a patient can only treat in places such as hospitals, specialized medical institutions and the like, and self-help training can not be carried out according to the own needs of the patient at any time and any place.
