Detailed implementation manner

[0040] The present invention will be further elaborated below in conjunction with specific illustrations.

[0041] Please refer to Figure 1 , the present invention provides a post - cardiac - surgery rehabilitation training device, including a base 100, a carrying chair 200 provided on the base 100 for carrying patients, a massage mechanism 300 provided on the carrying chair 200, an upper - limb lifting exercise mechanism and an upper - limb horizontal expansion exercise mechanism 500 provided on one side of the carrying chair 200, and a leg pedaling exercise mechanism 600, an adduction reciprocating exercise mechanism and a resistance flexion and extension exercise mechanism provided in front of the carrying chair 200 and connected to the base 100. The carrying chair 200 includes an angle - adjustable backrest 210, and the backrest 210 is connected with a first driving unit for controlling the inclination angle of the backrest 210. The first driving unit preferably adopts a hydraulic pump, and can also adopt a pneumatic push rod, etc. to realize the adjustment and control of the inclination angle of the backrest 210. By using the upper - limb lifting exercise mechanism, the training of the action of lifting both arms can be completed; the upper - limb horizontal expansion exercise mechanism 500 can carry out expansion training on both arms; the adduction reciprocating exercise mechanism can carry out knee - bending training on the lower limbs; the resistance flexion and extension exercise mechanism can carry out leg muscle strength training. By setting a variety of exercise mechanisms, patients can carry out comprehensive training of a variety of actions, effectively promoting limb blood circulation, increasing cardiopulmonary function, and helping patients after cardiac surgery recover soon; the combination of a variety of training actions can exercise the patient's body more comprehensively, avoiding the poor rehabilitation training effect caused by a single training action, and improving the rehabilitation training effect.

[0042] Several moving rollers 110 are connected to the lower end of the base 100, and the moving rollers 110 can assist in moving or transporting the device, facilitating use.

[0043] The carrying chair 200 further includes a plurality of support feet 220 provided on the base 100 and a chair seat board 230 connected to the upper ends of the plurality of support feet 220. The backrest 210 includes a backrest body 211 having one end pivotally connected to the chair seat board 230 and for installing the massage mechanism 300, and a covering member 212 detachably connected to the backrest body 211 and capable of covering the massage surface of the massage mechanism 300. The first driving unit is connected to the backrest body 211, and the backrest 210 can be adjusted to be flush with the top surface of the chair seat board 230 through the first driving unit. The training personnel can lie on the backrest 210 for back massage, or can choose to sit on the chair seat board 230, stretch their legs and contact the massage mechanism 300 on the backrest 210 to massage the legs.

[0044] The covering member 212 is preferably quickly connected to the backrest body 211 in a snap-fit or magnetic attraction connection manner. When the back does not need to be massaged, the massage surface is covered by the covering member 212, which is convenient for the training personnel to rely on for support.

[0045] Please refer to Figure 2 As shown, the backrest body 211 has an installation cavity, and two spaced-apart partition plates 2110 are provided in the installation cavity to divide the space in the installation cavity into three parts, thereby forming a first sub-cavity 2111, a second sub-cavity 2112, and a third sub-cavity 2113 that are independent of each other and arranged in sequence. The massage mechanism 300 includes a massage driving mechanism 310 connected to the backrest body 211, a plurality of massage rollers 320 connected to the massage driving mechanism 310 and arranged at intervals in the second sub-cavity 2112, massage protrusions 330 provided on the outer periphery of the massage rollers 320, and a flexible member 340 connected to the backrest body 210 and capable of closing the openings of the first sub-cavity 2111, the second sub-cavity 2112, and the third sub-cavity 2113. The flexible member 340 is preferably made of PVC material or silicone material, which is more comfortable for the training personnel to contact and is more convenient for cleaning after sweating. The massage driving mechanism 310 can drive the massage rollers 320 to rotate around their own axes, and a part of the massage rollers 320 protrudes out of the opening of the second sub-cavity 2112, and the covering member 212 can cover the flexible member 340. Dividing the installation cavity into three independent sub-cavities can reasonably layout the various components of the massage mechanism 300, help the various components not interfere with each other, make the overall structure more stable, and at the same time facilitate installation, maintenance, and repair, and extend the service life of the device.

[0046] Please continue to refer to Figure 2, the massage driving mechanism 310 includes a second driving unit 311 provided on the backrest body 211 and a transmission member connected to the second driving unit 311. The second driving unit 311 preferably uses an electric motor. The electric motor can provide continuous and stable power output. During the massage process, the rotation speed and direction of the electric motor can be accurately controlled according to actual needs, so as to precisely adjust the rotation speed and direction of the massage roller 320, providing the training personnel with massage experiences of different intensities and modes and meeting diverse massage needs.

[0047] The transmission member includes a plurality of sprockets that are connected to the massage rollers 320 one by one and are arranged at intervals in the first sub-chamber 2111, and a chain 312 sleeved on all the sprockets. The sprocket connected to the output end of the second driving unit 311 is defined as the driving sprocket, and the remaining sprockets are defined as the driven sprockets. For the transmission member composed of the sprockets and the chain 312, power is transmitted between the sprockets and the chain 312 through precise tooth engagement, with high transmission efficiency, and can efficiently transmit the power of the electric motor to each massage roller 320. This transmission method not only reduces power loss but also ensures the rotational synchronism of each massage roller 320. At the same time, the structure of the sprocket and chain 312 transmission is relatively simple, with relatively low requirements for installation accuracy, facilitating installation and debugging.

[0048] Please refer to Figures 3 - 5 , the massage roller 320 includes an outer cylinder 321 and an inner shaft 323 installed in the outer cylinder 321 through a first one-way bearing 322. The massage protrusions 330 are all installed on the outer cylinder 321. The massage protrusions 330 include a massage member 331 with one end exposed outside the outer cylinder 321 and the other end extending into the outer cylinder 321, a limiting member 332 connected to the outer periphery of the massage member 331 and located inside the outer cylinder 321, and a return spring 333 sleeved on the massage member 331. The return springs 333 are distributed between the limiting member 332 and the wall of the outer cylinder 321, and the massage member 331 can reciprocally move in the radial direction of the outer cylinder 321. Due to the elastic telescopic property of the massage protrusions 330, when encountering some protruding parts or sensitive areas of the body during the massage process, the massage protrusions 330 can appropriately retract, avoiding damage to the body caused by excessive force and improving the safety of the massage.

[0049] The inner shaft 323 includes a shaft main body 3230, several protruding members 3231 fixedly arranged on the outer periphery of the shaft main body 3230, and a first connection section 3232 and a second connection section respectively arranged at both ends of the shaft main body 3230. Among the two partition plates 2110, the partition plate 2110 close to the second driving unit 311 is defined as the first partition plate, and the partition plate 2110 far from the second driving unit 311 is defined as the second partition plate. One side of the first partition plate is connected to the outer cylinder 321 through a bearing assembly 350. The bearing assembly 350 includes a bearing seat 351 and a second one-way bearing 352 installed in the bearing seat 351. A two-way bearing 2210A is embedded in the first partition plate. The outer cylinder 321 is connected to the second one-way bearing 352 in the bearing seat 351, and the first connection section 3232 extends away from the shaft main body 3230 and is connected to the two-way bearing 2210A. Finally, the continuously extending first connection section 3232 enters the first chamber 2111, and this part of the first connection section 3232 located in the first chamber 2111 is used to connect to the driving wheel or the driven wheel.

[0050] A second one-way bearing 352 connected to the outer cylinder 321 is embedded in the second partition plate. The second connection section extends into the third chamber 2113. A plurality of second bearing seats 2113A are installed in the third chamber 2113. The second bearing seats 2113A are fixedly connected to the inner wall of the backrest body 211. A two-way bearing 2110A is installed in each of the second bearing seats 2113A located in the third chamber 2113. The second connection section is connected to the two-way bearing 2110A corresponding in position in the third chamber 2113. Bearings are connected to both ends of the inner shaft 323 and the outer cylinder 321, so that the massage roller 320 can maintain stability during rotation, reduce shaking and vibration, improve the comfort of massage and the service life of the massage roller 320. In addition, the stable rotation also helps to reduce the wear between transmission components and ensure the long-term stable operation of the entire massage driving mechanism 310. When the motor (i.e., the second driving unit 311) rotates in the first direction (for example, the motor rotates forward), the first one-way bearing 322 locks the inner shaft 323 and the outer cylinder 321. The first one-way bearing 322 forces the inner shaft 323 and the outer cylinder 321 to rotate synchronously. At this time, the outer cylinder 321 can rotate relative to the bearing seat 351, so as to realize the synchronous rotation of the inner shaft 323 and the outer cylinder 321 driven by the forward rotation of the motor, and realize the massage effect of scraping the back of the training personnel.

[0051] When the motor (i.e., the second driving unit 311) rotates in the second direction (e.g., the motor rotates in reverse), under the restriction of the first one-way bearing 322 and the second one-way bearing 352, at this time, the outer cylinder 321 and the bearing seat 351 are in a locked state and cannot rotate relative to each other, and the inner shaft 323 and the outer cylinder 321 can rotate relative to each other. Therefore, only the inner shaft 323 rotates alone in the second direction, and the outer cylinder 321 cannot rotate. The protrusion 3231 provided on the outer wall of the inner shaft 323 will abut against the massage member 331 during rotation. Therefore, the massage member 331 will be pushed out towards the outside of the outer cylinder 321. When the protrusion 3231 is separated from the massage member 331, the return spring 333 drives the massage member 331 to return to its original position, completing the reciprocating telescopic movement of the massage protrusion 330. In addition, in order to ensure the stability of the telescopic movement direction, a guide block is provided on the outer wall of the massage member 331, and a guide groove 3210 cooperating with the guide block is provided at the corresponding position of the outer cylinder 321. Connecting the outer cylinder 321 and the inner shaft 323 through the first one-way bearing 322 enables the massage roller 320 to present different working states under different rotations of the motor. The massage member 331 can perform reciprocating telescopic movement along the radial direction of the outer cylinder 321, which can better fit the contour and curve of the human back. During the massage process, the massage member 331 can be adaptively adjusted according to the undulations of the body surface, reducing the stiffness and discomfort during massage, and making the training personnel feel more comfortable during the massage process. The reciprocating telescopic movement and rotational scraping actions of the massage protrusion 330 can simulate various techniques of a masseur, such as pressing and scraping. This design of simulating manual massage techniques helps to more effectively relieve muscle tension, promote blood circulation, improve the therapeutic effect of massage, and has a positive effect on the rehabilitation of patients after heart surgery.

[0052] A number of massage protrusions 330 are arranged at intervals in sequence along the central axis direction of the outer cylinder 321 and are arranged in a spiral shape. The action connection between adjacent massage protrusions 330 is more coherent and smooth, without obvious pauses or jumps. This makes the massage process more stable and brings a more comfortable massage experience to the patient. The spiral arrangement makes the massage process more variable and interesting, avoiding the monotony that may be brought by directly distributing the protrusions, helping the training personnel to maintain a more positive attitude during the massage process, and improving their acceptance and cooperation with the rehabilitation training.

[0053] The protrusion 3231 is arranged along the central axis direction of the shaft main body 3230 and is arranged in a spiral shape. Please refer to Figure 7, the outer cylinder 321 is preferably provided with two helically arranged protruding members 3231. There are differences in the maximum dimensions of the two protruding members 3231 in the direction perpendicular to the axis of the shaft body 3230 (different in size). Therefore, due to the different sizes of the two protruding members 3231, during rotation, the larger protruding member 3231 can make the massage member 331 extend a longer distance out of the outer cylinder 321, exerting a greater pressure on the body surface, thereby providing a stronger massage stimulation; the smaller protruding member 3231 makes the massage member 331 extend a shorter distance, and the massage intensity is relatively lighter. In this way, during one massage process, different intensities of massage can be alternately experienced, meeting the differentiated requirements of different parts of the body for massage intensity, and enhancing the comfort and pertinence of the massage. It can form richer massage trajectories and coverage areas when the massage roller rotates. To a certain extent, select a suitable massage mode to achieve a personalized massage plan and better promote physical rehabilitation.

[0054] The upper limb lifting exercise mechanism includes two lifting exercise components 400 with the same structure and distributed on both sides of the chair seat plate 230. Each lifting exercise component 400 includes a first box body 410 connected to the base 100, an electric push rod 420 arranged in the first box body 410, a rotating cylinder 430 pivotally connected to the top end of the electric push rod 420, a hanging ring 440 arranged in the rotating cylinder 430, and a top plate 450 detachably connected to the rotating cylinder 430 and capable of closing the port of the rotating cylinder 430. A notch is provided on the side wall of the rotating cylinder 430 and is communicated with the inside of the rotating cylinder 430 for the hanging ring 440 to pass through. One end of the electric push rod 420 can extend out of the first box body 410 and is rotatably connected to the rotating cylinder 430 through components such as a rotating shaft. When a patient needs to perform the training of the upper arm lifting action, hold the hanging ring 440, and through the reciprocating movement of the electric push rod 420, drive the arms to move up and down, so as to realize the exercise of the upper arm lifting action. The electric push rod 420 is used to drive the arms for exercise. In the initial stage of training, a relatively low speed may be required to allow the patient to adapt to the action and the equipment; as the patient's physical condition improves and the adaptability increases, the moving speed of the electric push rod 420 can be gradually increased to increase the training intensity and help the patient better recover the strength and function of the upper limbs.

[0055] When the double-arm raising training is not required, the suspension rings 440 are stored in the rotating cylinder 430, and the top plate 450 closes the top end of the rotating cylinder 430 by screwing or clamping. At least two holding protrusions 431 are fixedly connected to the outer wall of the rotating cylinder 430 and are arranged at intervals and protrude away from the outer wall of the rotating cylinder 430. By holding the holding protrusions 431, the rotating cylinder 430 can be rotated horizontally repeatedly. When the rotating cylinder 430 is rotated, the wrist joint needs to perform a certain range of rotational motion. By repeatedly rotating the rotating cylinder 430 horizontally, the range of motion of the wrist joint can be increased, the flexibility and coordination of the wrist can be improved, and problems such as stiffness of the wrist joint due to long-term inactivity after surgery can be prevented. During the process of rotating the rotating cylinder 430, the muscles of the hand (such as finger flexors, extensors, thenar muscles and hypothenar muscles of the palm, etc.) need to continuously exert force to hold the holding protrusions 431 and apply a twisting force to drive the rotation of the rotating cylinder 430. This helps to enhance the grip strength and muscle strength of the hand, and has a positive effect on the recovery of the basic functions and strength of the hand for patients after heart surgery.

[0056] The upper limb horizontal extension exercise mechanism 500 includes two symmetrically arranged extension exercise mechanisms 500 respectively distributed on both sides of the chair seat plate 230. Please refer to Figure 6 and Figure 1, each expansion exercise mechanism 500 includes a second box body 510 connected to the base 100 and having a side opening 511, a folding plate 520 foldably connected to the second box body 510, and an expansion exercise component 530 disposed in the second box body 510. Chute grooves 540 are provided on the top surface of the second box body 510 and the folding plate 520. After the folding plate 520 is unfolded, the positions of the two chute grooves 540 can correspond to each other. The expansion exercise component 530 includes a slider 531 slidably connected to the chute groove 540, a main support rod 532 vertically connected to the lower end of the slider 531, a plurality of side rods 533 arranged at intervals on one side of the main support rod 532, a holding rod 534 connected to the side rods 533 and arranged in parallel with the main support rod 532, and a return component 535. The slider 531 can drive the main support rod 532 to enter / exit the side opening 511. The return component 535 includes a first connecting bolt 535A connected to the main support rod 532, a second connecting bolt 535B connected to the inner wall of the second box body 510, and a tension spring 535C connected between the first connecting bolt 535A and the second connecting bolt 535B. When expansion exercise is needed (similar to chest expansion exercise), unfold the folding plate 520, hold the side rods 533 and pull the slider 531 to perform the exercise. The operation is relatively simple, without complex operation steps and skills, easy to understand and master, and convenient for patients to independently perform rehabilitation training under the guidance of medical staff or family members. Pull the two side rods 533 to move back and forth. At this time, the muscles of the shoulders, arms and other parts of the upper limb (such as deltoid muscles, triceps brachii, etc.) need to exert force, so as to realize the expansion movement in the horizontal direction of the upper limb, effectively exercising the strength of the relevant muscle groups of the upper limb, and helping the patients after heart surgery to recover the strength and function of the upper limb. The elasticity of the tension spring 535C can be selected and adjusted according to the actual situation of the patient. For patients with weaker strength in the initial stage of recovery, a tension spring 535C with smaller elasticity can be selected to reduce the exercise difficulty; as the patient's physical condition improves and strength increases, a tension spring 535C with larger elasticity can be replaced to increase the exercise intensity, meeting the rehabilitation needs of patients in different stages.

A first through opening 120 communicating with the inside of the base 100 and arranged along the width direction of the base 100 is formed on the base 100. The third driving unit preferably adopts a motor. The position of the first lead screw corresponds to the position of the first through opening 120. The pedaling exercise component 620 can reciprocally move along the first through opening 120.

[0058] Please refer to Figure 7, the pedaling exercise component 620 includes a base 621 connected to the first nut, a central shaft mounted on the base 621, two cranks 622 respectively connected to both ends of the central shaft, and two pedals 623 connected to the cranks 622 in one-to-one correspondence. The exerciser sits on the seat board 230. After starting the third driving unit and the first lead screw rotates, the pedaling exercise component 620 moves towards the direction close to the seat board 230 until it reaches a position where the exerciser can step on the pedals 623 with both feet to perform pedaling motion training. The pedaling motion training involves the flexion and extension movements of the hip joint, knee joint, and ankle joint, which can increase the range of motion of these joints and improve the flexibility and flexibility of the joints. When not in use, the pedaling exercise component 620 can be moved to a position far from the seat board 230 by motor control to facilitate other exercise for the lower limbs.

[0059] Please refer to Figure 8 and Figure 1 , the adduction reciprocating exercise mechanism includes a second through port 130 arranged along the length direction of the base 100, a fourth driving unit arranged in the base 100, a second lead screw connected to the fourth driving unit and corresponding to the position of the second through port 130, a second nut connected to the second lead screw, and an adduction reciprocating exercise component 700 screwed to the second nut. The adduction reciprocating exercise component 700 includes a support seat 710 connected to the second nut and two grooves 720 arranged at intervals on the support seat 710. The groove 720 has an arc-shaped bottom surface 721, and a silica gel member 722 is fixedly connected to one end of the groove 720 close to the support foot 220. The exerciser sits on the seat board 230 and places both feet in the grooves 720. The arc-shaped bottom surface 721 is more convenient for the feet to fit and place, and the silica gel member 722 functions to prevent the feet from falling out of the grooves 720 at the heels. The fourth driving unit preferably uses a motor. After starting the fourth driving unit, the second lead screw rotates, which can drive the legs to reciprocally move towards or away from the seat board 230 to perform adduction knee flexion exercise. During the reciprocating motion, the hip joint, knee joint, and ankle joint are all exercised.

[0060] Please continue to refer to Figure 8, the resistance flexion and extension exercise mechanism includes two resistance flexion and extension exercise components 800 respectively fixed on both sides of the support base 710. Each resistance flexion and extension exercise component 800 includes a side seat 810 provided on one side of the support base 710, a placement recess 820 provided on the side seat 810, several springs fixed in the placement recess 820, and a placement foot plate 830 fixed at the top of the springs. Adjust the position of the support base 710 to be close to the chair seat board 230. Sit on the chair seat board 230, place both feet on the placement foot plate 830, and when performing resistance flexion and extension movements supported by the springs, the leg muscles need to overcome the resistance of the springs to complete the movement. This enables the main muscle groups such as the quadriceps femoris, hamstring muscles, and triceps surae of the legs to be fully exercised. Persisting in this for a long time can effectively enhance the strength and endurance of these muscles and improve the support and movement ability of the legs.

[0061] This device: First, this device integrates multiple exercise mechanisms, enabling upper limb training such as double-arm lifting and horizontal extension, as well as lower limb training such as pedaling, adduction and knee flexion, and resistance flexion and extension. It can comprehensively exercise the upper and lower limbs of patients. It avoids the problem of single traditional rehabilitation training movements, promotes limb blood circulation more comprehensively, increases cardiopulmonary function, and helps patients recover from heart surgery earlier. Second, patients do not need to perform separate training for the upper and lower limbs in different training venues or using different training equipment. They can complete comprehensive training for the upper and lower limbs on the same device, saving rehabilitation resources and time and improving the efficiency of rehabilitation training. Third, each exercise mechanism in the device can be adjusted according to the specific situation of the patient, such as the speed of the electric push rod 420, the elasticity of the tension spring 535C, and the resistance of the spring. When combining upper and lower limb exercises, patients can select different training intensities and methods according to the recovery conditions of their upper and lower limbs to achieve personalized rehabilitation training. Fourth, most exercises or massages rely on automated operations, making it more convenient and easier for exercise personnel to adapt to the exercise process. Fifth, the massage mechanism 300 with multiple massage methods can provide diverse choices. Patients can select appropriate massage methods according to their own situations to achieve personalized rehabilitation care and improve the acceptance and cooperation of patients with rehabilitation training.
