Description

Technical Field

[0001] The present invention relates to the technical field of rehabilitation training devices, and particularly relates to a rehabilitation four-limb linkage training device for nursing. Background Art

[0002] Rehabilitation four-limb linkage training is a comprehensive rehabilitation training method, mainly used to improve the coordination of limbs, muscle strength and joint range of motion. The four-limb linkage training equipment is usually a device similar to fitness equipment, with a seat, handles and pedals. The patient sits on the seat, holds the handles with both hands, and places the feet on the pedals. Its design allows the four limbs to move simultaneously, and the movement mode and rhythm can be adjusted according to the patient's condition. Based on the principle of neuromuscular plasticity, when the four limbs move simultaneously, the brain will receive a large amount of sensory information from the muscles and joints of the four limbs. The input of this information can stimulate the motor area of the cerebral cortex and promote the reconstruction and optimization of neural pathways. For patients with nervous system injuries, this repetitive and rhythmic movement helps to restore the brain's control ability over the limbs;

[0003] In the utility model with the application number 202022994767.4, a four-limb rehabilitation exercise device for rehabilitation nursing is disclosed. By stepping on the first rotating frame and holding the second rotating frame by the patient to rotate, the four limbs of the patient are exercised. The structure is simple and the operation is convenient. By rotating the screw rod, the moving frame moves in the fixed frame, which is convenient to adjust the positions of the first rotating frame and the second rotating frame according to the patient. Rotating the connecting shaft makes the gear rotate, and the cooperation between the gear and the tooth groove makes the connecting column move up and down, and the height of the seat can be adjusted, which is convenient for different patients to use;

[0004] However, the main applicable population of the above four-limb rehabilitation exercise device for rehabilitation nursing is patients with nervous system diseases and orthopedic diseases. The users themselves have problems of inconvenient movement and inflexible hands and feet, making it inconvenient for the users to transfer to the seat independently and requiring multiple nursing staff to assist in carrying, which increases the use threshold and difficulty of the device. In the above four-limb rehabilitation exercise device for rehabilitation nursing, the user cannot manually adjust the device according to their own needs, so additional nursing staff are required to assist in adjusting when the device is used, resulting in a relatively high use threshold and use cost of the device. Therefore, the present invention proposes a rehabilitation four-limb linkage training device for nursing to solve the problems existing in the prior art. Summary of the Invention

[0019] In order to deepen the understanding of the present invention, the following will further elaborate on the present invention in combination with embodiments. These embodiments are only used to explain the present invention and do not constitute a limitation to the protection scope of the present invention.

[0020] For stroke patients, four-limb linkage training can improve limb motor function. After a stroke, patients often experience hemiplegia on one side of the body. Four-limb linkage training can stimulate the recovery of the brain nerves, improve the muscle strength and coordination of the affected limb. For patients after fracture surgery, especially those with limb fractures (such as femoral fractures, humeral fractures, etc.) in the late stage of healing, four-limb linkage training helps to restore joint mobility and muscle strength. Taking femoral fracture as an example, after the removal of the fracture fixation, the muscles of the patient's lower limb may atrophy and joint movement will also be limited. Through four-limb linkage training, the patient can gradually increase the load and movement of the lower limb within a safe range, and at the same time drive the upper limb to perform coordinated movements, promoting blood circulation throughout the body and accelerating the rehabilitation process.
