Description

Technical Field

[0001] The present invention relates to the field of rehabilitation equipment, and in particular to a rehabilitation trainer capable of real-time monitoring of muscle fatigue degree. Background Technique

[0002] Rehabilitation equipment refers to devices or tools used to assist patients in rehabilitation treatment. Rehabilitation equipment can help patients with movement function disorders caused by injuries or illnesses to carry out targeted training. For example, after limb fractures or joint replacements, by using rehabilitation training devices such as joint movement trainers and lower limb ergometers, the range of motion of joints, muscle strength, and limb coordination can be gradually restored, improving the patient's motor ability and enabling the patient to walk, climb stairs, and complete daily activities normally again.

[0003] When performing rehabilitation training on the lower limbs, a rehabilitation trainer is required. However, when the current rehabilitation trainer is in use, it is difficult to monitor the muscle fatigue degree of the trainer in real time, which easily causes the trainer to overtrain, resulting in muscle strain and pain. Moreover, when an emergency occurs during training and the trainer urgently needs to rest, it is impossible to quickly provide rest support for the trainer, and the trainer can only be separated from the trainer, which will affect the rehabilitation progress of the trainer. Therefore, a rehabilitation trainer capable of real-time monitoring of muscle fatigue degree is provided. Summary of the Invention

A surface electromyogram sensor 16 is arranged inside the connecting belt 15. Through the arrangement of the connecting wire 14 and the connecting belt 15, the connecting belt 15 can be pasted on the leg of the trainer. And with the cooperation of the surface electromyogram sensor 16 and the visual sensor 2, the electromyogram signals of the muscle during contraction and relaxation can be collected, and the electromyogram data at different times will be continuously recorded to evaluate the muscle fatigue degree, analyze the limb movements of the trainer and observe the muscle morphology, so as to real-time monitor the muscle fatigue degree of the trainer, prevent the trainer from overtraining, and prevent the muscles of the trainer from being strained and painful. By using the provided first motor 5 to drive the screw rod 7 to rotate, the screw plate 8 and the rest seat 9 can be driven to move rightward to a suitable position, so that the trainer can sit on the soft seat plate 11 to rest, solving the problem that when the trainer encounters an emergency during training and urgently needs to rest, the trainer cannot be quickly provided with rest support.

[0026] In this embodiment, the training mechanism 1 includes two carrier plates 101. A second motor 102 is installed on the back of one carrier plate 101. Five groups of second bearings 103 are fixedly embedded on one side surface of each of the two carrier plates 101 that are close to each other. The inner rings of the ten groups of second bearings 103 are fixedly connected to ten rotating rods 104. A transmission belt 105 is commonly driven and connected to the outer surfaces of each of the rotating rods 104. The rear end of one rotating rod 104 is installed on the output end of the second motor 102. By setting the training mechanism 1, the second motor 102 can work, driving multiple rotating rods 104 and the transmission belt 105 to slowly rotate, enabling the trainee to perform walking training on the transmission belt 105. A pedal 19 is commonly installed on one side surface of the two carrier plates 101 that are close to each other. The pedal 19 is located to the right of the transmission belt 105.

Mounting openings 21 are formed on the upper surfaces of the two groups of mounting plates 20. A sliding opening 17 is formed on the front of one carrier plate 101. A sliding plate 18 is slidably connected inside the sliding opening 17. The back of the sliding plate 18 is installed on the front of the rest seat 9. By using the two vertical plates 22 and the two auxiliary grips 23, the trainee can hold them for support and auxiliary training. Through the control panel 25, the trainer can be regulated. By using the sliding opening 17 and the sliding plate 18, the movement of the rest seat 9 can be made more stable.

[0028] Working principle: First, connect the trainer to the power supply. Then, enable the trainee to get onto the transmission belt 105 through the pedal 19, and paste the connecting belt 15 on the trainee's leg. At the same time, start the training mechanism 1 to work, enabling the trainee to perform walking training on the transmission belt 105. During the training, the surface electromyography sensor 16 starts to collect the electromyographic signals of the muscles during contraction and relaxation, continuously recording the electromyographic data at different times to evaluate the muscle fatigue degree. Then, by using the work of the vision sensor 2, the limb movements of the trainee are analyzed and the muscle morphology is observed to monitor the muscle fatigue degree of the trainee in real time. When an emergency occurs during the training and rest is urgently needed, start the first motor 5 to drive the screw 7 to rotate, driving the screw plate 8 and the rest seat 9 to move to the right to a suitable position, enabling the trainee to sit on the soft seat plate 11 to rest.
