Description

Technical Field

[0001] The present invention relates to the technical field of medical rehabilitation equipment, and in particular to an auxiliary rehabilitation device. Background Art

[0002] Postoperative rehabilitation exercises are crucial in recovery after cardiovascular surgery, and their main goals are to help patients regain physical function, improve quality of life, and prevent complications. Early postoperative activity helps prevent complications such as venous thrombosis and pneumonia, while promoting the recovery of cardiovascular function. Rehabilitation exercise plans should be tailored to the patient's type of surgery and health status, starting with simple breathing exercises and passive movements, and gradually transitioning to low-intensity aerobic exercise and strength training. Throughout the process, patients must follow the doctor's advice, monitor physiological indicators, and adjust the intensity of exercise according to the progress of recovery. Through systematic rehabilitation exercises, patients can regain physical function faster, improve quality of life, and reduce the risk of long-term complications.

[0003] For example, a Chinese invention patent (CN113368469B) discloses a rehabilitation device for clinical nursing of cardiovascular surgery and a method of using the device, which states: "Through the pedals and wheels, the patient can train the muscles of the thigh, calf and buttocks during the pedaling process. During the training, the muscle fibers are slightly torn and then the protein intake promotes muscle growth, muscle strength and muscle endurance are improved. At the same time, the patient's heart rate slightly accelerates during pedaling, which helps the recovery of the condition. The exercise does not require the patient to get out of bed, meeting the urgent needs of current patients." It also states: "Existing rehabilitation measures generally require walking with the company of medical staff, or entering a rehabilitation treatment room for certain aerobic or anaerobic training. First of all, simple walking cannot achieve the required rehabilitation training intensity and will also consume the energy of medical staff. Secondly, some patients' conditions are not suitable for leaving the bed for a long time, and the rehabilitation treatment room is noisy and unsafe." Technical problems.

[0004] To sum up the above, it can be known that the prior art utilizes the patient's thigh, calf and buttocks muscles to be trained during the pedaling process. However, this method has the following technical problems: However, after actual cardiovascular surgery, some patients are relatively weak and cannot perform rehabilitation exercises through active exercise, and the device is not suitable for passive exercise rehabilitation exercises. For this reason, the present application proposes an auxiliary rehabilitation device to provide a new technical solution to solve the technical problems mentioned in the above patents. Summary of the invention

[0005] Based on this, it is necessary to provide an auxiliary rehabilitation device to address the above technical problems. The device passes the patient's hand through the first elastic band so that the four fingers except the thumb are inserted into the second elastic band, and the palm part is restricted by the first elastic band. Then the first motor can be controlled to drive the turntable to rotate, so that the extrusion block pushes the sliding column to slide inside the arc-shaped slide groove, thereby driving the patient's fingers and palm to bend. Then, when the sliding column cannot move due to the restriction of the arc-shaped slide groove, the extrusion block squeezes the sliding column as driven by the turntable, and then the extrusion block slides toward the inside of the fixed box, thereby releasing the extrusion on the sliding column, and then under the force of the torsion spring. Under the action, the finger plate can be rotated back to the initial position relative to the palm plate, thereby driving the patient's palm and fingers to straighten. Subsequently, with the continuous rotation of the turntable, the patient's palm and fingers can be driven to bend and straighten reciprocatingly, thereby allowing the patient's hand to perform passive movements to adapt to the use of weaker patients, helping patients maintain the range of motion of the hand joints, and preventing joint stiffness or contracture caused by long-term immobility. At the same time, passive movement of the hand helps to maintain or gradually restore the flexibility of the hand, preparing for future active movement. Passive movement can be used by weaker patients after surgery, thereby improving the practicality of the device.
