Cardiac rehabilitation adjuvant therapeutic device

Abstract

The present invention relates to the technical field of adjuvant rehabilitation apparatuses, and in particular to a cardiac rehabilitation adjuvant therapeutic device. The adjuvant therapeutic device comprises an exercise assistance mechanism, which is used for assisting a patient in doing reciprocating waist twisting exercises, the exercise assistance mechanism comprising a rotary disk. In the adjuvant therapeutic device of the present invention, when the pressure applied by a pressure spring to a bottom piston disk II decreases, the resistance that the patient is subjected to during waist twisting decreases; because a square cylinder is in communication with a four-way housing by means of a flexible tube, when the hydraulic pressure in the four-way housing decreases, the height of a rubber plate is also reduced, which causes the resistance between a friction plate and the rubber plate to be reduced, such that the resistance that the patient is subjected to also decreases when they do a knee bending exercise; therefore, when an increase in the patient's heart rate is measured by means of a heart rate strap, the exercise resistance of the device is correspondingly reduced; conversely, when the patient's heart rate gradually returns to a normal state, the exercise resistance is gradually increased by means of an adjustment mechanism, and thus the adjuvant therapeutic device can prevent a patient with a heart disease from doing exercise with an excessively high intensity and also helps the patient to undergo a cardiac rehabilitation treatment.

Description

Cardiac rehabilitation auxiliary treatment device Technical Field

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

[0002] Cardiac assisted rehabilitation therapy is a comprehensive treatment process aimed at improving cardiac function, improving quality of life, and reducing complications in patients with heart disease. During the rehabilitation period, patients with heart disease cannot simply rest in bed. In addition to scientific and standardized medication, they also need to focus on mental and psychological rehabilitation, dietary conditioning, and correcting bad habits. The most critical thing is exercise rehabilitation. Choosing appropriate and regular exercise can improve patients' heart function, improve quality of life, prolong prognosis, and reduce mortality from cardiovascular disease. Rehabilitation training and clinical drug treatment are two complementary and indispensable treatment links. Appropriate drug treatment can relatively enhance patients' exercise ability and improve training level and effect. At the same time, the beneficial effects of exercise training also help to gradually reduce the dosage of medication.

[0003] Cardiac rehabilitation patients should avoid excessive exercise during exercise to avoid increasing the burden on the heart. When the exercise intensity is too high, the myocardial oxygen consumption capacity cannot be met, which will lead to myocardial hypoxia. When the patient's heart rate is too high, it will also affect cardiac diastole, thereby affecting the heart's pumping function, which will reduce the heart's output and cannot meet the needs of various parts of the body. Therefore, cardiac rehabilitation patients need to adjust the resistance and intensity of the equipment according to their heart rate during exercise. The existing rehabilitation assistive equipment is relatively cumbersome to adjust the resistance of exercise equipment, and it is difficult to automatically adjust according to the heart rate of the rehabilitation patient.

[0060] The air bag is arranged on the top of the regulating cylinder and contacts the top of the piston disc.

[0061] Compared with the prior art, the present invention has the following beneficial effects:

[0062] 1. The patient can twist his body left and right to drive the turntable to rotate. The rotation of the turntable can drive the piston block to slide in the arc sleeve through the arc rod, so that the air can be pressed into the regulating cylinder through the connecting pipe. Under the action of air pressure, the piston disc 2 will be squeezed to rise, and then the pressure spring will contract. The pressure spring will form a reverse force on the piston disc 2. Therefore, the patient will encounter a certain resistance during the twisting process. This resistance can be automatically adjusted based on the patient's heart rate to ensure that the patient's exercise intensity adapts, so that the patient can exercise his waist, exercise the waist muscles, and promote blood circulation in the waist. The patient's feet can be tied to two foot pedals, and then the patient can do knee flexion movements. As the patient's feet drive the foot pedals When the patient is standing on the step board, the limit block at the end of the footrest is kept sliding with the limit groove, so that the footrest can drive the sliding plate and the friction plate at the bottom to move together. Since the compression spring squeezes the sliding plate and the friction plate downward to keep them in contact with the rubber plate, the patient will also feel a certain resistance when bending his knees, which helps to exercise the patient's thigh and calf strength and tighten the blood circulation in the legs. The patient can improve his own heart function through proper waist and leg exercises, and can assist the patient's cardiac rehabilitation. The combination of waist exercise and leg exercise can help long-term bedridden patients to perform cardiac rehabilitation exercises, instead of directly exercising through walking or sprinting, so as to avoid excessive burden on the patient's heart.

[0063] 2. The heart rate belt can be used to detect the patient's heart rate during exercise, and the detected heart rate data can be transmitted to the microcontroller for signal processing and heart rate calculation. The heart rate data is converted into a PWM signal by the microcontroller, and then the PWM signal is transmitted to the motor driver. The driver controls the speed of the motor according to the PWM signal. By mapping the heart rate value to the PWM model of the belt, the higher the heart rate, the smaller the PWM duty cycle, thereby reducing the speed of the motor. The reflection in the device is that the speed of the impeller driven by the output end of the drive motor decreases, so that less water is pumped into the four-way shell from the liquid storage tank. Since the end of the four-way shell maintains the flow through the throttle valve, the hydraulic pressure in the four-way shell will decrease, and then the hydraulic pressure of the hydraulic rod will decrease, so that the hydraulic rod will drop under the squeeze of the extrusion spring, causing the piston to disc. After the descent, the air in the two airbags can be extracted, so the airbags will gradually shrink, and the position of the piston disc 2 at the top will rise, so that the pressure of the pressure spring on the bottom piston disc 2 will be reduced, so that the resistance encountered by the patient when twisting his waist will be reduced. Since the square cylinder and the four-way shell are connected by a hose, when the hydraulic pressure in the four-way shell decreases, the height of the rubber plate will also decrease, so that the resistance between the friction plate and the rubber plate will decrease, and even the rubber plate and the friction plate will separate, so that the resistance encountered by the patient when bending his knees will also be reduced. When the heart rate belt detects that the patient's heart rate has increased, the movement resistance of the device will decrease accordingly. Conversely, when the patient's heart rate gradually returns to normal, the adjustment mechanism will gradually increase the movement resistance, thereby preventing heart disease patients from exercising too hard and helping them to undergo cardiac rehabilitation treatment.

The exercise assistance mechanism 100 includes a turntable 101; a knee bending mechanism 200 for assisting the patient in performing leg knee bending exercises, and the knee bending mechanism 200 is fixedly arranged at the bottom of the turntable 101; an adjustment mechanism 300 for automatically adjusting the exercise resistance according to the patient's heart rate. The adjustment mechanism 300 includes a liquid storage tank 301. The top of the liquid storage tank 301 is fixedly connected with a control box 303. A microcontroller is fixedly connected inside the control box 303. The top of the control box 303 is fixedly connected with a driving motor 302. An electric motor drive module is fixedly connected to the driving motor 302. The bottom of the driving motor 302 is fixedly connected with a circular shell 304. An impeller 305 is fixedly connected to the output end of the driving motor 302. One side of the circular shell 304 is fixedly connected with a four-way shell 308.

[0079] Specifically, the patient can sit on the turntable 101 and then rotate the U-shaped rod 107. The end of the U-shaped rod 107 will abut against the clamping block 110, and then the return spring 111 can squeeze the clamping block 110 into the interior of the U-shaped rod 107 to lock it. A heart rate belt 109 needs to be worn on the patient's wrist to detect the patient's heart rate. The patient can twist the body left and right to drive the turntable 101 to rotate. The rotation of the turntable 101 enables the piston block 114 to slide in the arc-shaped sleeve 115 through the arc-shaped rod 113, so that air can be pressed into the adjustment cylinder 316 through the connecting pipe 116. Under the action of air pressure, the piston plate two 318 will be squeezed to rise, and then the pressure spring 319 contracts. The pressure spring 319 will form a reverse acting force on the piston plate two 318. Therefore, the patient will be subject to a certain resistance during the twisting process. This resistance can be automatically adjusted based on the patient's heart rate, ensuring that the patient's exercise intensity is suitable, enabling the patient to exercise the waist of his own, exercising the waist muscles, and promoting blood circulation in the waist. The patient's feet can be bound to two footrests 204, and then the patient can perform knee bending actions. As the patient's feet drive the footrests 204, the limit blocks 205 at the ends of the footrests 204 are kept sliding with the limit grooves 202, enabling the footrests 204 to drive the sliding plate 207 and the friction plate 209 at the bottom to move together. Since the compression spring 208 will squeeze the sliding plate 207 and the friction plate 209 downward to keep in contact with the rubber plate 210, the patient will also have a certain sense of resistance when bending the knees. This helps to exercise the strength of the patient's thighs and calves and promotes blood circulation in the legs. The patient can appropriately exercise the waist and legs to help improve the function of his own heart and assist the patient's heart rehabilitation. By combining waist exercise and leg exercise, it can help bedridden patients for a long time to perform heart rehabilitation exercises, rather than directly exercising by walking or sprinting, avoiding excessive burden on the patient's heart;

[0080] The heart rate belt 109 can be used to detect the patient's heart rate during exercise, and the detected heart rate data can be transmitted to the microcontroller for signal processing and heart rate calculation. The heart rate data is converted into a PWM signal by the microcontroller, and then the PWM signal is transmitted to the motor driver. The driver controls the speed of the motor according to the PWM signal. By mapping the heart rate value to the PWM model of the belt, the higher the heart rate, the smaller the PWM duty cycle, thereby reducing the speed of the motor. The reflection in the device is that the speed of the impeller 305 driven by the output end of the drive motor 302 decreases, so that less water is pumped into the four-way shell 308 from the liquid storage tank 301. Since the end of the four-way shell 308 maintains the flow through the throttle valve 309, the hydraulic pressure in the four-way shell 308 will decrease, and then the hydraulic pressure of the hydraulic rod 311 will decrease, so that the hydraulic rod 311 will drop under the squeezing of the squeezing spring 312, so that the piston disc 1 313 can move the two air cylinders after it drops. The air in the bag 320 is extracted, so the air bag 320 will gradually shrink, and the position of the piston disc 2 318 at the top will rise, so that the pressure of the pressure spring 319 on the bottom piston disc 2 318 will be reduced, so that the resistance encountered by the patient when twisting his waist will be reduced. Since the square cylinder 212 and the four-way shell 308 are connected by the hose 213, when the hydraulic pressure in the four-way shell 308 decreases, the height of the rubber plate 210 will also decrease, so that the resistance between the friction plate 209 and the rubber plate 210 will decrease, and even the rubber plate 210 and the friction plate 209 will separate, so that the resistance encountered by the patient when bending his knees will also be reduced. When the heart rate belt 109 detects that the patient's heart rate is rising, the movement resistance of the device will decrease accordingly. Conversely, when the patient's heart rate gradually returns to normal, the adjustment mechanism 300 will gradually increase the movement resistance, thereby preventing heart disease patients from exercising too hard and helping them to undergo cardiac rehabilitation treatment.

[0081] Example 1

[0082] As shown in FIG. 3-8, in this embodiment, the exercise assistance mechanism 100 includes: a backrest 102 fixedly connected to the top of the turntable 101; a seat cushion 103 fixedly arranged on the turntable 101; a rotating column 104 fixedly connected to the center position at the bottom of the turntable 101; a support frame 105 rotatably sleeved outside the rotating column 104; two L-shaped plates 106 symmetrically and fixedly connected to the top of the support frame 105; one end of a C-shaped rod 107 is rotatably connected to the L-shaped plate 106; two holding handles 108 are symmetrically and fixedly connected to the side walls of the C-shaped rod 107; a heart rate belt 109 is fixedly connected to the side wall of the C-shaped rod 107. A clamping block 110 is slidably and embeddedly connected in the L-shaped plate 106. The end of the clamping block 110 is fixedly connected to a pull rod 112. A return spring 111 is sleeved outside the pull rod 112, and the end of the return spring 111 is fixedly connected to the inner wall of the L-shaped plate 106. Two arc-shaped rods 113 are symmetrically and fixedly connected to the outer wall of the rotating column 104; two piston blocks 114 are fixedly connected to the ends of the arc-shaped rods 113; two arc-shaped sleeves 115 are slidably sleeved outside the arc-shaped rods 113; two connecting pipes 116, one end of each is fixedly connected to the end of the arc-shaped sleeve 115, and the arc-shaped sleeve 115 is internally connected to the connecting pipe 116; two positioning arms 117 are fixedly sleeved outside the arc-shaped sleeve 115.

[0083] The knee bending mechanism 200 includes: a support plate 201 for supporting the patient's legs; two limiting grooves 202 symmetrically opened in the support plate 201; a positioning seat 203 fixedly connected to the bottom of the turntable 101, and the end of the support plate 201 is fixedly connected to the positioning seat 203; two foot pedals 204 are slidably and embeddedly connected in the limiting grooves 202; two limiting blocks 205 are fixedly connected to the side walls of the foot pedals 204, and the limiting blocks 205 are slidably and embeddedly connected to the limiting grooves 202; two binding straps 206, the ends of which are fixedly connected to the side walls of the foot pedals 204; two sliding plates 207 are slidably sleeved at the bottom ends of the foot pedals 204; two compression springs 208 are fixedly connected to the tops of the sliding plates 207. The knee bending mechanism 200 includes: a friction plate 209 fixedly connected between the bottoms of the two sliding plates 207; a rubber plate 210 slidably abuts against the bottom of the friction plate 209; a telescopic plate 211 is fixedly connected to the center position at the bottom of the rubber plate 210. A square tube 212 is slidably sleeved with the telescopic plate 211; one end of a hose 213 is fixedly connected to the bottom of the square tube 212, and the square tube 212 is internally connected to the hose 213; two limiting rods 214 are symmetrically and fixedly connected to the bottom of the support plate 201, and the rubber plate 210 is slidably sleeved with the limiting rods 214.

[0084] During specific implementation, the patient can sit on the turntable 101, and then rotate the U-shaped rod 107. The end of the U-shaped rod 107 will抵触 the clamping block 110, and then the return spring 111 can squeeze the clamping block 110 to pop into the interior of the U-shaped rod 107 to lock it. A heart rate belt 109 needs to be worn on the patient's wrist to detect the patient's heart rate. The patient can twist the body left and right to drive the turntable 101 to rotate. The rotation of the turntable 101 enables the piston block 114 to slide in the arc-shaped sleeve 115 through the arc-shaped rod 113, so that air can be pressed into the adjustment cylinder 316 through the connecting pipe 116. Under the action of air pressure, the piston plate two 318 will be squeezed to rise, and then the pressure spring 319 will contract. The pressure spring 319 will form a reverse acting force on the piston plate two 318. Therefore, the patient will be subject to a certain resistance during the twisting process. This resistance can be automatically adjusted based on the patient's heart rate, ensuring that the patient's exercise intensity is suitable, enabling the patient to exercise the waist, exercise the waist muscles, and promote blood circulation in the waist;

[0085] The patient's feet can be bound to the two footrests 204, and then the patient can perform a knee bending action. As the patient's feet drive the footrests 204, the limit blocks 205 at the ends of the footrests 204 are kept sliding with the limit slots 202, enabling the footrests 204 to drive the sliding plate 207 and the friction plate 209 at the bottom to move together. Since the compression spring 208 will squeeze the sliding plate 207 and the friction plate 209 downward to keep抵触 the rubber plate 210, the patient will also have a certain sense of resistance when bending the knees. This helps to exercise the patient's thigh and calf strength and promote blood circulation in the legs. The patient can appropriately exercise the waist and legs to help improve the function of their own heart and assist the patient's heart rehabilitation. Combining waist exercise and leg exercise can help bedridden patients for a long time to carry out heart rehabilitation exercise, rather than directly exercising by walking or sprinting, avoiding causing too much burden on the patient's heart.

[0086] Embodiment 2

[0087] As shown in Figures 9-12, in this embodiment, the regulating mechanism 300 includes: a straight cylinder 306 fixedly connected to the bottom of the circular shell 304; an auger 307 fixedly connected to the center of the impeller 305 and rotatably sleeved inside the straight cylinder 306; a throttle valve 309 fixedly connected to the end of the spool housing 308. A sealing cylinder 310 fixedly connected to the top of the spool housing 308 and communicating with the interior of the spool housing 308; a hydraulic rod 311 slidably sleeved inside the sealing cylinder 310; a compression spring 312 fixedly sleeved outside the hydraulic rod 311; a piston disc 1 313 fixedly connected to the top of the hydraulic rod 311; an air cylinder 314 slidably sleeved with the piston disc 1 313; and a branch pipe 315 fixedly connected to the top center of the air cylinder 314. There are two regulating cylinders 316, which are symmetrically fixedly connected to the ends of the branch pipe 315; the one-way valve 317 is fixedly set on the outer wall of the regulating cylinder 316; there are two piston discs 318, which are slidably sleeved inside the regulating cylinder 316, and a circular ring that limits the position of the bottom piston disc 318 is fixedly connected to the inner wall of the regulating cylinder 316; there are three pressure springs 319, which are fixedly connected between the two piston discs 318; the airbag 320 is set at the top of the regulating cylinder 316, and conflicts with the top of the piston disc 318.

[0088] In a specific implementation, the heart rate belt 109 can detect the patient's heart rate during exercise, and then the detected heart rate data can be transmitted to the microcontroller for signal processing and heart rate calculation. The microcontroller converts the heart rate data into a PWM signal, and then transmits the PWM signal to the motor driver. The driver controls the speed of the motor according to the PWM signal. By mapping the heart rate value to the PWM model of the belt, the higher the heart rate, the smaller the PWM duty cycle, thereby reducing the speed of the motor;

[0089] The reaction in the device is that the output end of the driving motor 302 drives the speed of the impeller 305 to decrease, so that the less water is pumped from the liquid storage tank 301 into the four-way shell 308. Since the end of the four-way shell 308 maintains the flow through the throttle valve 309, the hydraulic pressure in the four-way shell 308 will decrease, and then the hydraulic pressure of the hydraulic rod 311 will be reduced, so that the hydraulic rod 311 will drop under the pressure of the extrusion spring 312, so that the piston disc 1 313 can extract the air in the two air bags 320 after it drops, so the air bags 320 will gradually shrink, so that the position of the piston disc 2 318 at the top will rise, so that the pressure of the pressure spring 319 on the bottom piston disc 2 318 is reduced, so that the patient can The resistance encountered when the waist is twisted will be reduced. Since the square cylinder 212 and the four-way shell 308 are connected by the hose 213, when the hydraulic pressure in the four-way shell 308 decreases, the height of the rubber plate 210 will also decrease, so that the resistance between the friction plate 209 and the rubber plate 210 will decrease, and even the rubber plate 210 and the friction plate 209 will separate. In this way, the resistance encountered by the patient during knee flexion exercise will also be reduced. Therefore, when the heart rate belt 109 detects that the patient's heart rate increases, the movement resistance of the device will decrease accordingly. Conversely, when the patient's heart rate gradually returns to normal, the adjustment mechanism 300 will gradually increase the movement resistance, thereby preventing heart disease patients from exercising too hard and helping them to undergo cardiac rehabilitation treatment.
