Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a novel upper limb motor function rehabilitation machine. Background Art

[0002] Stroke is the second leading cause of death and the third leading cause of death and disability worldwide. According to statistics, as of 2019, an estimated 101 million stroke patients were diagnosed worldwide. Over the past 20 years, the global cost of stroke has increased significantly. With the aging population and accelerated urbanization, the incidence of stroke in my country has been increasing annually, with younger patients being diagnosed. While advances in medical technology have reduced the mortality rate among stroke patients, most stroke patients lose hand motor function, developing hemiplegia and the ability to move independently after recovery.

[0003] Existing motor function rehabilitation machines cannot be truly used for motor rehabilitation treatment of patients with limited upper limb motor function caused by upper limb muscle damage or hemiplegia and cerebral infarction, and cannot help patients with independent or coupled movement of the elbow and wrist joints. Therefore, they are not very practical. To this end, we propose a new upper limb motor function rehabilitation machine. Utility Model Content

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide a new upper limb motor function rehabilitation machine that can help patients' elbow and wrist joints to move independently or in a coupled manner. It can be adjusted according to the size of the patient's forearm and both the left and right arms can be used. It can also be connected to external control signals to help patients with rehabilitation training, which can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the present utility model provides the following technical solutions: a novel upper limb motor function rehabilitation machine, comprising a placement table;

[0006] A support rod is installed at the lower end of the placement table, and a base is fixedly installed at the lower end of the support rod. A display screen is provided on the right side of the placement table, and a control box is provided at the upper end of the placement table. A large arm fixed base is provided at the upper end of the control box. A rotating block 1 is provided on one side of the control box, and a gear 1 and a gear 2 are provided on the rotating block 1. A rotating block 2 is provided on one side of the rotating block 1, and a small arm fixed base is provided on one side of the rotating block 2. A fixed block is provided on one side of the small arm fixed base, and a handle is provided on the fixed block.

[0007] A rotating motor is installed at one end of the control box, and the other end of the rotating motor is fixedly connected to the rotating block 1. The rotating block 1 is rotatably provided with gear 1 and gear 2. The output shaft of the rotating motor passes through the rotating block 1 and is fixedly connected to the gear 2. The gear 2 is engaged with the gear 1, and the gear 1 is rotatably connected to the rotating block 1. The other side of the rotating block 1 is rotatably provided with the rotating block 2. The input end of the rotating motor is electrically connected to the output end of the control box.

[0008] When the device receives a wrist joint movement instruction, the rotating motor starts to run and drives gear one to rotate, and gear one then drives gear two to rotate. The patient holds the handle with his hand, thereby achieving auxiliary movement of the patient's wrist. When the handle rotates clockwise, it is suitable for right arm rehabilitation exercise, and when the handle moves counterclockwise, it is suitable for left arm rehabilitation exercise, which can help patients perform rehabilitation training and speed up the rehabilitation process.

[0009] Furthermore, the output shaft of the gear 2 on the rotating block 1 passes through the rotating block 1 and is fixedly connected to the rotating block 2. A forearm fixing base is symmetrically installed at one end of the rotating block 2. A pad is fixedly installed at one end of the forearm fixing base, and a fixed block is installed above the pad.

[0010] Gear 2 drives gear 1 to rotate, and the rotation of gear 1 drives rotating block 2 to rotate, thereby adjusting the position of rotating block 2 and adjusting the position of the patient's wrist joint.

[0011] Furthermore, a drive motor is installed at one end of the fixed block, and a handle shaft is provided at the other end of the fixed block. The output shaft of the drive motor passes through the fixed block and is fixedly connected to the handle shaft. The handle shaft is fixedly connected to the handle, and the input end of the drive motor is electrically connected to the output end of the control box.

[0012] The driving motor drives the handle shaft to start rotating, and the handle shaft drives the handle to perform independent rehabilitation exercises on the patient's wrist joint, and can also perform synchronous coupled rehabilitation exercises, which is highly practical.

[0013] Furthermore, a grip hole is fixedly installed on the inner end of the handle, and a grip ring is fixedly installed on the outer end of the handle.

[0014] The setting of the grip hole and grip ring makes it easy for patients to hold the handle firmly, preventing their fingers from slipping under the handle and affecting the recovery progress.

[0015] Furthermore, a boom fixing base is fixedly mounted on the upper end of the control box, a boom gasket is mounted on the boom fixing base, and the upper end of the boom fixing base is connected to a boom strap.

[0016] Place the patient's upper arm on the upper arm pad, place the forearm on the forearm pad, adjust the position of the upper arm, and fix the upper arm to the upper arm fixed base with the upper arm strap, then adjust the fixed position of the forearm and fix the forearm to the forearm fixed base to fix the patient's arm.

[0017] Furthermore, a connecting frame is fixedly installed on the right side of the placement table, a display screen is fixedly installed on the upper end of the connecting frame, and the input end of the display screen is electrically connected to the output end of the control box.

[0018] The display screen is placed in front of the patient, and the input data comes from the control box, including the patient's upper limb position and posture information and compensatory movement monitoring results; on the one hand, the display screen can display the patient's upper limb position and posture and compensatory movement monitoring results in real time; on the other hand, it can guide the patient to actively inhibit compensatory movement through the control box, thereby stimulating the enthusiasm and initiative of rehabilitation training.

[0019] Compared with the existing technology, the beneficial effects of the present invention are: the new upper limb motor function rehabilitation machine has the following advantages:

[0020] 1. When the device receives a wrist joint movement instruction, the rotary motor starts running and drives gear one to rotate, which in turn drives gear two to rotate. The patient holds the handle to achieve auxiliary movement of the patient's wrist. When the handle rotates clockwise, it is suitable for right arm rehabilitation exercise, and when the handle moves counterclockwise, it is suitable for left arm rehabilitation exercise. It can help patients conduct rehabilitation training and speed up the rehabilitation process.

[0021] 2. Place the patient's upper arm on the upper arm gasket, place the forearm on the forearm gasket, adjust the position of the upper arm, and fix the upper arm to the upper arm fixed base with the upper arm strap. Then adjust the fixed position of the forearm and fix the forearm to the forearm fixed base to fix the patient's arm.

[0022] 3. The display screen is placed in front of the patient, and the input data comes from the control box, including the patient's upper limb position and posture information and compensatory movement monitoring results; on the one hand, the display screen can display the patient's upper limb position and posture and compensatory movement monitoring results in real time; on the other hand, it can guide the patient to actively inhibit compensatory movement through the control box, thereby stimulating the enthusiasm and initiative of rehabilitation training.
