[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: The structure of the present invention is scientific and reasonable, and it is safe and convenient to use: 1. A convenient exercise mechanism is provided. The foot of the patient is limited by the footrest plate and the limiting foot sleeve, so that the footrest plate stepped on by the patient deflects upward and downward around the positioning shaft. During the deflection process, the arc-shaped pressing block is blocked by the airbag. The gas filled in the airbag provides resistance to the deflection. And the airbag blocks the deflection of the footrest plate in two directions. Thus, the patient can realize the exercise of ankle dorsiflexion and plantar flexion. The operation is more convenient and the applicability is wider; At the same time, the solenoid valve is used to control the rate at which the air flow is squeezed out of the airbag, and the air inflation pump can adjust the internal pressure of the airbag. The combination of the two provides great convenience for changing the resistance size, and it is convenient to adjust according to the exercise process of the patient. The exercise and detection effects are more scientific and accurate, preventing the patient from being damaged due to excessive resistance during exercise exceeding the bearing range of the lower limb veins or the exercise effect being poor due to too small resistance. And the solenoid valve control method is simple, and the sudden resistance training can be provided by closing it to cause the air flow to be unable to be discharged. The two-way control training provides more intelligent and accurate assistance for the patient's exercise.
[0015] 2. The binding cloth can be attached to the lower limb of the patient by using the binding strap. The lower limb muscles are monitored by the near-infrared spectrum sensor, and the blood flow and muscle changes of the lower limb can be accurately understood, providing accurate data comparison for the prevention of thrombosis in the lower limb of the patient and enabling the real-time monitoring of the exercise results.
[0016] 3. By cooperating with each other, the laser emitter and the laser receiver monitor the rotation and tilt angle of the footrest plate, providing precise angle changes for the patient's exercise, improving the accuracy of the exercise, adjusting the angle to be tilted each time according to the patient's exercise needs, and preventing excessive dorsiflexion and plantar flexion of the patient from causing damage to the ankle joint; The position of the laser receiver can be adjusted through the deflection rod and the rotating shaft to meet the patient's exercise needs. At the same time, the positioning gear is limited and fixed by the compression spring and the limit block, so that the deflection rod remains stable after the position adjustment.
[0017] 4. A commutation support mechanism is provided. The driving motor drives the rotating disc to rotate, and the orientation of the support seat can be adjusted. When the patient sits down, it moves away from the footrest plate, improving the safety of use, preventing the patient's legs from colliding with structures such as the footrest plate, and the hydraulic telescopic rod can change its height to adapt to patients of different heights; At the same time, the electric push rod pushes the leg-lifting inclined plate to move, and the leg-lifting inclined plate is used to lift the lower limb part of the patient, making the lower limb higher than the footrest plate. There will be no collision when adjusting the direction, and it is more labor-saving to use. There is no need to manually lift the legs to the symmetrical position, preventing the elderly patients from having difficulty in lifting their legs. The guide strip plate and the moving block cooperate with each other to guide the leg-lifting inclined plate and improve the stability of its movement.
[0018] In summary, by combining the convenient exercise mechanism and the commutation support mechanism, assisting in exercise and preparation work respectively, it provides great convenience for the patient's detection and preventive exercise, making the patient's exercise more labor-saving, the operation more accurate, enabling the patient to operate by himself, reducing the restrictions on exercise, having a wider scope of application, and at the same time using the near-infrared spectroscopy sensor to monitor the change of oxyhemoglobin in the soleus muscle of the patient, collecting data during the patient's lower limb exercise, and generating a thrombus risk index.

Moreover, the hydraulic telescopic rods 505 can change its height to adapt to patients of different heights; At the same time, the electric push rod 507 pushes the leg-lifting inclined plate 509 to move, and uses the leg-lifting inclined plate 509 to lift the lower limb part of the patient, making the lower limb higher than the footrest plate 403, so that there will be no collision during the adjustment of the direction, and it is more labor-saving to use, without the need for manual leg-lifting to the symmetrical position, preventing the elderly patients from having difficulty in the leg-lifting operation. The guide strip plates 511 and the moving clamping blocks 510 cooperate with each other to play a guiding role for the leg-lifting inclined plate 509 and improve the stability of its movement.
[0023] The working principle and usage process of the present invention: First, the patient needs to adjust according to their exercise needs. Press down the limit clamping block 429, the compression spring 428 is compressed, the movable rod 427 and the limit clamping block 429 both descend, and no longer limit the positioning gear 425. Rotate the deflection rod 422 so that it deflects upward or downward around the rotating shaft 421, changing the position of the laser receiver 423. If dorsiflexion exercise is needed, that is, the laser receiver 423 needs to be moved upward to a certain inclination angle, and for plantar flexion exercise, that is, downward inclination. Then release the limit clamping block 429, the compression spring 428 resets and elongates upward, and the top end of the limit clamping block 429 is inserted into the teeth on the side of the positioning gear 425, making the rotating shaft 421 and the deflection rod 422 no longer rotate; Then, the drive motor 503 is controlled to drive the rotating disc 504 and the support seat 506 to rotate, adjust the orientation of the support seat 506, which facilitates the patient to sit on the support seat 506 from the side away from the footrest plate 403. At the same time, the hydraulic telescopic rod 505 will extend or contract to adapt to the patient's height. After the patient sits on the support seat 506, the lower leg part of the lower limb naturally hangs down outside the support seat 506. The electric push rod 507 extends forward, pushing the leg-lifting inclined plate 509 to move forward along the guiding strip plate 511, extending from below the support seat 506, contacting the patient's lower limb and pushing the lower limb to turn up, which increases the height of the patient's lower limb. Thus, when the patient operates the drive motor 503 to drive it to rotate with the support seat 506, it will not collide with structures such as the footrest plate 403. After adjusting the patient to the predetermined position, the two lower limbs correspond to the two footrest plates 403. The electric push rod 507 contracts backward, and the leg-lifting inclined plate 509 gradually moves downward below the support seat 506, gradually lowering the patient's lower limb so that the two feet correspond and are placed on the footrest plates 403; Next, the patient steps on the footrest plate 403, and the two forefeet are respectively inserted into the two limit foot sleeves 404. The binding cloth 417 is attached to the patient's lower limb by using the binding strap 418, and the near-infrared spectrum sensor 419 is closely attached to the patient's lower limb. The near-infrared spectrum sensor 419 is used to monitor the change of oxyhemoglobin in the patient's soleus muscle, collect data during the patient's lower limb exercise, and generate a thrombus risk index; If dorsiflexion exercise is required, the patient controls the air pump 415 near the lower part of the heel to start, inflate the air bags 410 inside the two arc-shaped fixing frames 409 near the lower part of the heel. According to the patient's exercise pressure requirement, adjust the air pressure inside the air bags 410, and use the solenoid valve 416 to change the gas discharge efficiency. The patient steps on the footrest plate 403 and toes upward for dorsiflexion exercise, so that the footrest plate 403 rotates around the positioning shaft 402, the part of the forefoot deflects upward, and the part of the heel presses down. The corresponding arc-shaped pressing block 408 gradually embeds into the inside of the arc-shaped fixing frame 409, squeezing the lower pressing block 412 and the air bag 410. The gas inside the air bag 410 generates damping, and thus the lower limb on which the patient exerts force is exercised. The fixing rod 405 rotates with the footrest plate 403, and the guiding frame 406 plays a guiding role for the fixing rod 405 until the laser emitter 424 at the end of the fixing rod 405 moves upward to a certain position and corresponds to the laser receiver 423, and the emitted laser is received by the laser receiver 423, and the patient stops further dorsiflexion; If plantar flexion exercise is needed, the patient controls the air pump 415 under the front sole to inflate the corresponding two air bags 410. When performing plantar flexion, the front sole drives the foot support plate 403 to deflect and tilt downward, squeezing the corresponding air bags 410. The gas inside the air bags 410 generates resistance, achieving the corresponding exercise. Moreover, during the dorsiflexion and plantar flexion exercise processes, the patient can control the solenoid valve 416 to suddenly close, so that the gas inside the air bags 410 no longer discharges outward when being squeezed, providing sudden resistance and corresponding sudden exercise for the patient's lower limbs.
[0024] Finally, it should be noted that the above are only preferred examples of the present invention and are not used to limit the present invention.
