Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a rehabilitation aid for training elderly people with mild cognitive impairment. Background Art

[0002] Mild cognitive impairment is an intermediate state between normal aging and dementia. Its core symptom is the decline of cognitive function, but the ability to carry out daily life is not significantly affected. When it is found that the elderly have mild cognitive impairment, they need to undergo a combination of cognitive + motor training. Cognitive training is the use of tablets for Chinese character recognition, picture recognition, name and face memory, and spatial memory. Cognitive training can maintain or partially improve the cognitive function of the elderly; motor training is the use of equipment for planned exercise training. Exercise training can slow down the aging rate of the elderly's digital computing ability, thereby enabling the elderly to prevent and alleviate mild cognitive impairment.

[0003] According to the Dalian University of Technology's report "Study on the Effects of Different Exercise Intervention Modes on Improving Cognitive Function in the Elderly under the Perspective of Active Health", Dr. Guo Linxuan's team explored the effects of exercise intensity (taking high-intensity interval training as an example) on cognitive function. The results showed that unlike traditional aerobic training, high-intensity interval training has a significant effect on the executive ability of people with depression in a short period of time, and there is a significant correlation between the improvement of cognitive function and physical function.

[0004] Most existing rehabilitation training aids can only perform one-sided training during training, and it is difficult to switch between high-intensity interval training and aerobic training. In addition, high-intensity interval training is directly entered without a buffering link, which easily makes it difficult for patients to adapt and leads to poor rehabilitation training results. It is difficult for existing rehabilitation training aids to change the maximum intensity of training during high-intensity interval training, so that patients can only use one intensity for training, which further reduces the rehabilitation training effect of patients. Summary of the invention

[0005] In order to overcome the shortcomings of existing rehabilitation training aids that it is difficult to switch between high-intensity interval training and aerobic training, and it is difficult to change the training intensity during high-intensity interval training, resulting in insufficient rehabilitation training effect for patients, the purpose of the present invention is to provide a rehabilitation aid for training elderly people with mild cognitive impairment that can select aerobic exercise or intermittent high-intensity exercise according to the patient's condition, and allows the patient to train at different intensities, thereby improving the patient's rehabilitation training effect.

[0010] As an improvement to the above solution, the friction surface of the friction frame can fit with the rotating wheel.

[0011] As an improvement of the above scheme, it also includes a pressure mechanism, which is arranged on the friction mechanism and is used to compress the spring seat. The pressure mechanism includes a lifting plate, a rotating cylinder, a guide rod, an overrunning clutch, a fixed frame, a rotating ring and a fixed protrusion. A lifting plate is fixedly connected between the two spring seats, and the lifting plate is slidably connected to the support seat.

[0012] As an improvement of the above solution, the guide rod and the fixed protrusion are made of steel.

[0015] The present invention has the following advantages: 1. The movable plate continues to move upward to compress the spring seat, and the compression of the spring seat makes the friction frame and the rotating wheel contact more closely, so that the resistance to the rotation of the rotating wheel is gradually increased, and then the force of the patient stepping on the pedal assembly is gradually increased, so that the patient can perform high-intensity training; the force applied by the friction frame to the wheel rotation is reduced, so that the resistance to the rotation of the rotating wheel is gradually reduced, and then the force of the patient stepping on the pedal assembly is gradually reduced, so that the patient can perform intermittent high-intensity exercise, and thus the patient's rehabilitation training effect is better.

[0016] 2. Reversing the rotating cylinder 90 degrees will cause the guide groove on the rotating cylinder to squeeze the extrusion rod and cause the rotating cylinder to move upward. The upward movement of the rotating cylinder will drive the lifting plate to move upward, and the upward movement of the lifting plate will drive the bottom of the spring seat to move upward. The upward movement of the bottom of the spring seat compresses the spring seat; the friction frame moves upward and contacts the rotating wheel and stops moving, and the lifting plate continues to move upward, which will further compress the spring seat, further increasing the resistance to the rotation of the rotating wheel, thereby further increasing the training intensity of the patient; in the process of reversing the rotating cylinder 90 degrees, the straight groove of the rotating cylinder will contact the guide rod, and the spring seat will drive the lifting plate, the rotating cylinder and the overrunning clutch to move downward, and the rotating cylinder continues to reverse, returning the rotating cylinder to its initial position; the patient's high-intensity exercise intensity is increased or decreased in a continuous cycle, so that the patient can train at different intensities, thereby further improving the patient's rehabilitation training effect.

[0017] 3. The movement of the threaded rod will drive the extrusion rod and the connecting frame to move; the upward movement of the friction frame will drive the protrusion to move upward, and the upward movement of the protrusion will contact the adjusted extrusion rod, so that the friction frame will not contact the rotating wheel, and aerobic exercise or intermittent high-intensity exercise can be selected according to the patient's condition, thereby making it possible to adapt to different types of patients.

The reciprocating screw rod 74 is used to drive the lifting plate 75 to move back and forth.

[0032] The friction mechanism 8 includes a movable plate 81, a friction frame 82 and a spring seat 83. The movable plate 81 is slidably connected to the support seat 4, and the movable plate 81 is welded to two lifting plates 75. The friction frame 82 is slidably connected to the movable plate 81, and two spring seats 83 are fixedly connected to the friction frame 82.

[0033] The friction surface of the friction frame 82 can fit with the rotating wheel 6 .

[0034] At first, the medical staff guides the patient to sit on the chair 2, and then the medical staff guides the patient to put his feet on both sides of the foot pedal assembly 5 respectively. Finally, under the guidance of the medical staff, the patient begins to step on the foot pedal assembly 5 and makes the foot pedal assembly 5 rotate.
