Detailed Implementation

[0019] To further understand the invention's content, features, and effects, the following embodiments are provided for detailed explanation.

[0020] Please see Figure 1 , Figure 2 and Figure 3 The postoperative rehabilitation training device for cardiology of the present invention includes a thigh pad 20, a back pad 6 at the rear of the thigh pad 20, two lower leg pads 13 at the front, and a head pad 3 at the rear of the back pad 6. The thigh pad 20 supports the patient's thighs, the back pad 6 supports the patient's back, the head pad 3 supports the patient's head, and the two lower leg pads 13 support the patient's lower legs. During rehabilitation training, the patient sits on the thigh pad 20, with their back resting on the back pad 6, their head resting on the head pad 3, and their lower legs resting on the two lower leg pads 13.

[0021] In this embodiment, a thigh pad 10 is installed on the thigh pad 20, a back pad 7 is installed on the back pad 6, a head pad 5 is installed on the head pad 3, and a calf pad 14 is installed on the calf pad 13. The pads on each pad are used to improve the comfort of the patient during postoperative rehabilitation training.

[0022] In this embodiment, a movable base 1 is also included. A support platform 2 is installed in the middle of the movable base 1, and a base frame 11 is installed at the bottom of the thigh pad 20. The top of the support platform 2 is fixedly connected to the base frame 11. The movable base 1 consists of a chassis and brake rollers, so the rehabilitation training device can be flexibly moved as needed. The support platform 2 is used to provide stable support for the main body above. Since the thigh pad 20 is fixed to the top of the support platform 2 through the base frame 11, it can be seen that the thigh pad 20 is fixed.

[0023] In this embodiment, multiple side fixing seats 22 are provided on the sides of the back pad 6, thigh pad 20, and calf pad 13. Guardrails 9 are installed on each set of side fixing seats 22. The guardrails 9 are detachable, allowing them to be installed on the sides of each pad when necessary, providing some protection for patients undergoing rehabilitation training and preventing falls. In this embodiment, grip bars 16 are installed in the middle of the front part of each of the two calf pads 13. The two grip bars 16 are used by medical personnel to intervene in rehabilitation training movements. When performing opening and closing and flexion-extension movements of the lower limbs, medical personnel use the grip bars 16 to operate the two calf pads 13 to perform left-right opening and closing movements and up-and-down swinging movements.

[0024] A neck joint assembly 4 is installed between the back pad 6 and the head pad 3 to adjust the up-and-down swing angle and displacement of the head pad 3. A lumbar joint assembly 8 is installed between the thigh pad 20 and the back pad 6 to adjust the up-and-down swing angle of the back pad 6. A knee joint assembly 12 is installed between the thigh pad 20 and each calf pad 13 to allow the calf pad 13 to swing up-and-down and left-and-right.

[0025] The neck joint assembly 4 allows for forward and backward movement and angle adjustment of the head pad 3 and its head cushion 5, thus providing good support for the patient's head. The lumbar joint assembly 8 allows for angle adjustment of the back pad 6 and its back cushion 7, thus setting the posture of the patient's upper body and providing good back support. The knee joint assembly 12 allows the two calf pads 13 and their calf cushions 14 to swing left and right and up and down, with the left and right swing corresponding to the aforementioned opening and closing training movements of the lower limbs, and the up and down swing corresponding to the aforementioned flexion and extension training movements of the lower limbs.

[0026] Please see Figure 3 and Figure 4 It can be seen that: The neck joint assembly 4 includes two neck joint mechanisms, one on the left and one on the right. Simultaneous operation of the two neck joint mechanisms enables the forward and backward movement and angle adjustment of the head pad 3.

[0027] The neck joint mechanism includes a neck fixation seat 4-3 mounted and fixed on the headrest 3 and a neck adjustment seat 4-5 mounted and fixed on the backrest 6. Both the neck fixation seat 4-3 and the neck adjustment seat 4-5 have through holes running from front to back. A neck locking rod 4-2 is installed in the through hole of the neck fixation seat 4-3, and a neck telescopic rod 4-6 is installed in the through hole of the neck adjustment seat 4-5. A neck toothed seat 4-4 is pivotally mounted on the front of the neck fixation seat 4-3, and the front of the neck toothed seat 4-4 is fixedly connected to the rear end of the neck telescopic rod 4-6. The front end of the neck locking rod 4-2 has teeth that mate with the neck toothed seat 4-4. A neck locking member 4-7 for locking the neck telescopic rod 4-6 is installed at the bottom of the neck adjustment seat 4-5.

[0028] A connecting rod 4-1 is installed between the rear ends of the two neck locking rods 4-2. The connecting rod 4-1 allows the two neck locking rods 4-2 to move forward or backward simultaneously.

[0029] As shown in the figure, the neck locking member 4-7 is a threaded rod with a knob. A threaded hole is provided in the center of the bottom of the neck adjusting seat 4-5. The threaded rod of the neck locking member 4-7 is located in this threaded hole, and its end abuts against the neck telescopic rod 4-6. When forward or backward movement is required, simultaneously release the neck locking members 4-7 of both left and right neck joint mechanisms. Push or pull the neck telescopic rod 4-6 forward or backward on the neck adjusting seat 4-5, and then lock the two neck locking members 4-7. When adjusting the set angle, pull the connecting rod 4-1 backward to move the two neck locking rods 4-2 backward. This separates the front teeth from the neck tooth seat 4-4, allowing for vertical angle adjustment. After adjustment, push the connecting rod 4-1 forward to move the two neck locking rods 4-2 forward until the front teeth of the neck locking rods 4-2 re-engage with the neck tooth seat 4-4.

[0030] Please see Figure 3 and Figure 5 It can be seen that: The waist joint assembly 8 includes a drive box 8-3 mounted on the rear end of one side of the base frame 11. A worm gear mechanism consisting of a worm wheel 8-4 and a worm 8-6 is installed inside the drive box 8-3. A transmission box 8-2 and an adjusting handwheel 8-1 are mounted at the front of the drive box 8-3. The transmission box 8-2 transmits the driving action of the adjusting handwheel 8-1 to the worm 8-6. Specifically, the transmission box 8-2 includes a housing and a drive shaft located inside the housing. The front end of the drive shaft is fixedly connected to the worm 8-6, and the rear end of the drive shaft is connected to the inner end of the rotating shaft of the adjusting handwheel 8-1 via a bevel gear set. Thus, by adjusting the handwheel 8-1, the worm 8-6 can be driven to rotate forward or backward, thereby driving the worm wheel 8-4 to rotate forward or backward.

[0031] A first connecting seat 8-5 is installed at the rear of the worm gear 8-4, and a second connecting seat 8-7 is hinged to the rear end of the other side of the base frame 11. The first connecting seat 8-5 and the second connecting seat 8-7 are fixedly connected to the front of the back pad 6. In this way, when the operating adjustment handwheel 8-1 is turned forward or backward, the back pad 6 can swing up or down. During rehabilitation training, the back pad 6 and its back cushion 7 should be adjusted to a comfortable back support angle for the patient. Then, the head pad 3 and its head cushion 5 should be adjusted to a suitable head support angle so that the patient is in a relatively comfortable posture to receive postoperative rehabilitation training.

[0032] In this embodiment, the lumbar joint assembly 8 further includes an elastic mechanism 21, which includes a front base 21-2, a rear base 21-3, and a gas spring 21-1 located between the two. The front base 21-2 is fixedly connected to the backrest pad 6, and the rear base 21-3 is fixedly connected to the base frame 11. The elastic mechanism 21 provides a certain elastic force during adjustment, improving the stability of the movement. When the backrest pad 6 moves upward, the gas spring 21-1 further extends; conversely, when the backrest pad 6 moves downward, the gas spring 21-1 further contracts.

[0033] Please see Figure 3 and Figure 5 It can be seen that: The knee joint assembly 12 includes two knee joint mechanisms, left and right. Simultaneous operation of the two knee joint mechanisms enables the two calf pads 13 and their calf pads 14 to move left and right and up and down. When moving left and right, it achieves the training effect of opening and closing movements of the lower limbs, and when moving up and down, it achieves the training effect of flexion and extension movements of the lower limbs.

[0034] The knee joint mechanism 12 includes a transition seat 12-1 fixedly connected to the base frame 11. A knee tooth seat 12-4 is provided on the transition seat 12-1. A swing arm 12-2 is pivotally mounted on the knee tooth seat 12-4. A through hole is provided on the swing arm 12-2, and a knee locking rod 12-6 is provided in the through hole. The front end of the knee locking rod 12-6 is provided with teeth that cooperate with the knee tooth seat 12-4.

[0035] It also includes a rotating seat 12-3 pivotally connected to the front end of the swing arm 12-2 and a knee locking member 12-5 for locking the rotating seat 12-3. The rotating seat 12-3 is fixedly connected to the rear of the calf pad 13.

[0036] When the knee locking lever 12-6 is pulled away from the knee gear seat 12-4, the teeth separate from the knee gear seat 12-4, allowing the calf pad 13 to swing up and down. When the front teeth of the knee locking lever 12-6 re-engage with the knee gear seat 12-4, the calf pad 1 is locked in the longitudinal direction. When the knee locking element 12-5 releases its locking effect on the rotating seat 12-3, the calf pad 13 can swing left and right. As shown in the figure, the knee locking component 12-5 is a threaded rod with a knob. The end of the swing arm 12-2 is provided with a longitudinal through hole and the threaded rod is located in the through hole. The rotating seat 12-3 is provided with a threaded hole and the threaded rod of the knee locking component 12-5 is located in the threaded hole. When the knee locking component 12-5 is tightened, the swing arm 12-2 and the rotating seat 12-3 are combined into one unit. When the knee locking component 12-5 is loosened, the rotating seat 12-3 and its lower leg pad 13 can move left and right.

[0037] Each calf pad 13 is equipped with a foot pedal assembly 15 that can move elastically back and forth and perform a hooking motion. The calf pad 14 is provided with a pad-shaped hole 19. A foot pedal assembly 18 is also installed at the front of the thigh pad 20. The foot pedal assembly 18 is flipped down when not in use and flipped up when in use.

[0038] Please see Figure 6 It can be seen that: The pedal assembly 15 includes a slide bar 15-3 with a slider 15-2 and a spring 15-1. The spring 15-1 is located in front of the slider 15-2 and provides a backward elastic force to the slider 15-2. The slide bar 15-3 is mounted in a strip hole on a calf pad 13, which is located below the strip hole 19 on the pad.

[0039] The top of the slider 15-2 is provided with a connecting part, and the bottom of the slider 15-2 is also connected to the connecting part of the slider 15-2 by insertion. A foot plate 15-5 is hinged on the support base 15-4. A limiting block is provided on the support base 15-4 and in front of the root of the foot plate 15-5. An operating rod 15-6 is provided at the top front of the foot plate 15-5. A strap 15-7 for fixing the foot is provided on the foot plate 15-5.

[0040] As shown in the figure, the support base 15-4 is inserted into the connecting part of the slider 15-2, so the part of the foot pedal assembly 15 exposed in the strip hole 19 on the pad can be removed and installed at any time during use. Because there is a limiting block in front of the heel of the foot plate 15-5, the foot plate 15-5 cannot continue to swing forward, but can only swing backward (that is, towards the patient's body), which is the flexion movement. The strap 15-7 is used to tie and fix the patient's foot, and the operating lever 15-6 is used for medical staff to hold. By making the foot plate 15-5 and the foot swing backward intermittently, the continuous flexion training movement is achieved.

[0041] In addition, when the patient's foot is fixed on the footplate 15-5, the patient's lower limb can actively step down. When stepping down, the slider 15-2 moves forward on the slider 15-3 and the spring 15-1 is further compressed. The spring 15-1 provides a damping effect. When released (that is, when the knee is slightly bent), the slider 15-2 moves backward on the slider 15-3 and the spring 15-1 is further extended.

[0042] Please see Figure 7 It can be seen that: The foot pedal assembly 18 includes a support rod 18-1, a rear axle 18-3 at the rear end and a front axle 18-6 at the front end of the support rod 18-1, bushings 18-2 at both ends of the rear axle 18-3 and the bushings 18-2 are fixed to the front of the base frame 11, and a bracket 18-4 at the middle of the support rod 18-1, on which a foot pedal 18-5 is mounted. In this embodiment, sleeves 17 are installed at the bottom of the two lower leg pads 13, and when the foot pedal assembly 18 is in use, both ends of the front axle 18-6 are located inside the left and right sleeves 17.

[0043] The pedal assembly 18 provides patients with a rehabilitation exercise effect similar to cycling. When not in use, the pedal assembly 18 is in a state of... Figure 1 The folded state shown is located below the calf pad 13. When the pedal assembly 18 is activated, the two calf pads 13 are first moved outward, then the pedal assembly 18 is flipped upward, and then the two calf pads 13 are moved inward so that the two sleeves 17 are fitted onto the left and right ends of the front axle rod 18-6. After that, the patient can start cycling training.

[0044] How to use: Transfer the patient onto the device and adjust the angles of the back pad 6 and head pad 3 to a suitable position. The patient's back is supported by the back pad 6 and back pad 7, and the head is supported by the head pad 3 and head pad 5. In the early postoperative stage, rehabilitation training is mainly performed by medical staff, including lower limb opening and closing, lower limb flexion and extension, and foot flexion. In the mid-postoperative stage, under the guidance and intervention of medical staff, rehabilitation training is mainly performed by the patient on their own.

[0045] Lower limb opening and closing exercises operated by medical staff: Release the knee locking devices 12-5 of the two knee joint components 12. Using the lever 16, the medical staff manipulates the two calf pads 13 and their calf pads 14 to open them horizontally outwards and then inwards, repeating this several times. This provides multiple opening and closing exercises for the patient's lower limbs. Lower limb flexion and extension exercises operated by medical staff: Keeping the knee locking devices 12-5 of the two knee joint components 12 locked, pull the two knee locking levers 12-6 to release the locking of the knee teeth 12-4. Using the lever 16, the medical staff manipulates the two calf pads 13 and their calf pads 14 to swing them downwards and then return them to their original position, repeating this several times. This provides multiple flexion and extension exercises for the alternating lower limbs. Ankle flexion exercises operated by medical staff: Fix the patient's foot to the foot pedal component 15. Using the lever 15-6, the medical staff intermittently and repeatedly swings the footplate 15-5, providing multiple ankle flexion exercises for the patient.

[0046] Patient self-flexion: The patient's foot is fixed to the pedal assembly 15, and the patient actively performs multiple flexion exercises. Patient self-pedaling: The patient's foot is fixed to the pedal assembly 15, and the patient actively performs multiple elastic pedaling exercises. Patient self-pedaling: The pedal assembly 18 is flipped up and fixed with the sleeves 17 of the two calf pads 13, after which the patient performs continuous pedaling training for a certain period of time.
