Description

Technical Field

[0001] This invention belongs to the technical field of training equipment for muscle atrophy, and specifically relates to a training device for patients with muscle atrophy. Background Technology

[0002] Patients with muscular atrophy often need to engage in consistent exercise to rehabilitate and stretch various parts of their body during rehabilitation. If they lack exercise, they may become bedridden due to muscle weakness, leading to various complications. This is especially true for elderly patients with muscular atrophy. When exercising on conventional rehabilitation equipment, someone often needs to accompany them to prevent falls caused by sudden weakness and secondary injuries. However, existing muscle training equipment often uses elastic bands, and most of these bands deteriorate over time. In China, due to quality issues and frequency of use, elastic bands often suffer from severe aging and wear, frequently breaking and injuring patients or caregivers. For patients with muscle atrophy, the rebound force generated when the elastic band breaks can easily cause further impact and injury to already atrophied muscles. Furthermore, conventional preventative measures can lead to excessive and rapid stretching of local joints or limbs, resulting in muscle strains and posing significant safety concerns. Moreover, existing rehabilitation equipment is too limited in its application to muscle training for joints such as fingers, and it can also easily lead to medical disputes.

[0003] Therefore, patent document CN 114534170A discloses a rehabilitation training device for patients with muscular atrophy, including a bed and several sliding mechanisms. The sliding mechanisms are located on the bed and have fixing components for fixing them to the bed. The sliding mechanisms also have telescopic components, and the telescopic ends of the telescopic components have snap-fit ​​components for snapping different telescopic components together. The telescopic components have several hollow elastic ropes fixedly connected to them. The other end of each elastic rope has a shell with finger sleeves and a gripping component. The different elastic ropes all pass through the gripping component. The elastic ropes have insulating connecting wires inside. This device can prevent patients from falling due to the breakage of the elastic ropes used for exercise during rehabilitation, and can also prevent broken elastic ropes from hitting caregivers or patients. At the same time, it can exercise multiple muscle groups in the patient simultaneously and improve the applicability of the device.

[0004] However, the rehabilitation training device in the cited document can only train the upper limbs, and cannot train the lower limbs separately or train the upper and lower limbs synchronously and in a coordinated manner. This makes the rehabilitation training device in the cited document less practical and the training effect poor.

[0005] Therefore, there is an urgent need to design a training device for patients with muscle atrophy to solve the above problems. Summary of the Invention

[0006] To address the limitations of existing muscular atrophy training devices, which can only train the upper limbs and cannot train the lower limbs independently or provide synchronous and coordinated training, this invention provides a highly integrated, safe, reliable training device for muscular atrophy patients that can meet multiple training modes. The device includes a frame, a lower limb training mechanism, an upper limb training mechanism, a counterweight device, and an automatic disconnection device. The lower limb training mechanism is located at the lower end of the frame and is used for leg lifting training; the upper limb training mechanism is located at the upper end of the frame and is used for arm pull-down training. Both share the same adjustable counterweight device as a resistance source. The automatic disconnection device enables multiple modes of independent and coordinated training for the upper and lower limbs. Furthermore, by incorporating an automatic winding device and a buffer device, interference from the ropes during training is avoided, and cushioning protection is provided under stress conditions. Therefore, this invention provides muscular atrophy patients with a compact, easy-to-operate, comprehensive, safe, and effective rehabilitation training device.

[0009] Preferably, the upper limb training device includes: Two pull rings; Two pull rope assemblies, one end of which is connected to two pull rings respectively, and the other end is connected to a counterweight device.

[0010] Preferably, the two pull cord assemblies include: A pull strap, one end of which is connected to a pull ring and located below the end of the second pull rope; The third pull rope is connected at one end to the end of the pull belt and at the other end to the counterweight device.

[0011] Preferably, the automatic disconnection device two includes: Two seats are symmetrically arranged on the pull strap; Electromagnet one is connected to the end of the second pull rope away from the leg fixing device; Two magnets are respectively slidably mounted in two bases, and the two magnets have opposite magnetic properties.

[0012] Preferably, the automatic disconnection device includes: The L-shaped slider is slidably mounted on the frame, with its end connected to the first pull rope. A magnetic column is embedded in the L-shaped slider. The fixed block is slidably mounted on the frame and has an electromagnet inside that works in conjunction with the magnetic column. The end of the fixed block is connected to the counterweight device via a fourth pull rope.

[0013] Preferably, the device further includes two sets of automatic winding devices, one end of which is connected to two third pull ropes and two fourth pull ropes respectively, and the other end of each device is connected to a counterweight device, so as to facilitate the winding of the third pull ropes and the fourth pull ropes respectively.

[0014] Preferably, the automatic winding device includes: The lower end of the winding body is connected to the counterweight device. A torsion spring is installed in the inner cavity of the winding body, with one end connected to the inner wall of the winding body.

The piston rod has one end movably inserted into the second buffer cylinder to exchange the liquid between the first and second buffer cylinders, and the other end is connected to the winding body.

[0017] A second objective of this invention is to provide a training method for patients with muscular atrophy, the method being based on a training device for patients with muscular atrophy, the method comprising: S1. Independent upper limb training is conducted using an upper limb training mechanism and weights. S2. Independent upper limb training is conducted using a lower limb training mechanism and a weight device; S3. The lower limb training mechanism is disconnected by automatic disconnection device one and automatic disconnection device two, and part of it is connected to the upper limb training mechanism. The upper and lower limbs are then trained in conjunction with the counterweight device.

[0018] The beneficial effects of this invention are: This invention discloses a training device for patients with muscular atrophy. Compared with the prior art, the improvement of this invention lies in: (1) This invention, through its cleverly designed frame, lower limb training mechanism, upper limb training mechanism, and shared counterweight device, coupled with an automatic disconnection device, enables three modes of training—independent upper limb training, independent lower limb training, and coordinated upper and lower limb training—to be performed on a single device. This greatly satisfies the differentiated training needs of patients with muscle atrophy at different stages and in different parts of their rehabilitation, avoiding the cost and space occupation of purchasing multiple single-function devices. Furthermore, by sharing a single counterweight device and frame, and switching training modes through an automatic disconnection device (electromagnetic control connection / disconnection), the entire device structure is relatively simplified, compact, and small in size, making it suitable for home or small rehabilitation institutions. The high degree of automation in switching training modes reduces the tedious steps of manually disassembling and assembling parts, improving ease of use.

[0019] (2) The buffer device added in this invention uses the principle of hydraulic damping to effectively slow down the falling speed of the counterweight device if the patient loses strength during training, thus avoiding secondary injury or psychological fright to the user due to the rapid fall of the heavy object, and significantly improving the safety of the training process.

[0020] (3) The automatic winding device of the present invention can automatically wind up the pull ropes that are not involved in the training (such as the third pull rope or the fourth pull rope) in a specific training mode, effectively preventing them from getting tangled with the pull ropes in use due to slack or folding, or interfering with the normal movement trajectory of the counterweight device, thus ensuring the smoothness of the training process and the reliability of the equipment operation.

[0021] (4) The counterweight device of this invention adopts a design that allows for the addition or removal of counterweight blocks, which allows for flexible adjustment of the training load according to the patient's rehabilitation progress and individual strength differences, realizing personalized and progressive adjustment of training intensity, which is conducive to the scientific and effective nature of rehabilitation training; the lower limb training mechanism is equipped with a training seat and an arc-shaped leg fixation device with straps, providing patients with a stable and comfortable seated training environment; the upper limb training mechanism adopts a pull ring design, which conforms to the human body's gripping habits. The overall design takes into account the user's comfort and ease of use. Attached Figure Description

[0030] Furthermore, the accompanying drawings are not drawn to a 1:1 scale, and the relative dimensions of the components are shown in the drawings only as examples and not necessarily to actual scale.

[0031] Example 1: See attached document Figure 1-13 The training device for patients with muscular atrophy shown includes a frame 1, on which a lower limb training mechanism 2, an upper limb training mechanism 3, and a counterweight device 4 are also provided. The lower limb training mechanism 2 is located at the lower end of the frame 1 and is connected to an automatic disconnection device 5. The lower limb training mechanism 2 can be used for lower limb training alone. The upper limb training mechanism 3 is located at the upper end of the frame 1 and is connected to the lower limb training mechanism 2 through an automatic disconnection device 6. The upper limb training mechanism 3 can be used for upper limb training alone, or in conjunction with the lower limb training mechanism 2 to achieve synchronous and coordinated training of the upper and lower limbs.

[0032] The counterweight device 4 is located inside the frame 1 and is connected to the lower limb training mechanism 2 and the upper limb training mechanism 3. That is, the lower limb training mechanism 2 and the upper limb training mechanism 3 share a counterweight device 4 for training. The two are used in conjunction with the automatic disconnection device 1 5 and the automatic disconnection device 2 6 to achieve individual or coordinated training of the upper and lower limbs.

[0033] The training device for patients with muscle atrophy in this embodiment utilizes the upper limb training mechanism 3 and the lower limb training mechanism 2 to perform individual upper and lower limb training, as well as coordinated upper and lower limb training. In both individual and coordinated upper and lower limb training, a counterweight device 4 is used, making the structure of the device relatively simple and the size small, while meeting the various training needs of patients with muscle atrophy.

[0034] In the embodiments of this application, reference is made to the appendix. Figures 5-6 As shown, the lower limb training mechanism 2 includes a training seat 201, two leg fixing devices 202, two first pull ropes 203 and two second pull ropes 204. The training seat 201 is fixedly embedded in the lower end of the frame 1 to facilitate the patient's sitting posture when performing lower limb training. Two leg fixation devices 202 are symmetrically rotated and installed at the front end of the training seat 201. The leg fixation devices 202 have a concave arc structure and multiple straps (not shown in the figure) are provided on the leg fixation devices 202. When the patient's leg is placed in the leg fixation device 202, the straps can be used to firmly fix the patient's leg to the leg fixation device 202, ensuring that the lower limb moves synchronously with the leg fixation device 202 during training.

[0035] Two first pull ropes 203 are fixedly connected at one end to two leg fixing devices 202, and at the other end to the counterweight device 4 via corresponding automatic disconnection devices 5. Specifically, one end of the first pull rope 203 is fixedly connected to the leg fixing device 202, and the other end is fixedly connected to the automatic disconnection device 5. A fourth pull rope 504 is fixedly connected to the other end of the automatic disconnection device 5, and the other end of the fourth pull rope 504 is connected to the counterweight device 4. The automatic disconnection device 5 is slidably embedded in the frame 1. One end of each of the two second pull ropes 204 is fixedly connected to one of the two leg fixing devices 202, and the other end is connected to the upper limb training mechanism 3 through the corresponding automatic disconnection device 6.

[0036] During lower limb training, the patient sits on the training chair 201 and places both legs in the two leg fixation devices 202 respectively. The legs are then secured to the two leg fixation devices 202 with straps. The patient then slowly raises their legs, causing the two leg fixation devices 202 to move the two first pull ropes 203 outward relative to the body. The two first pull ropes 203 cause the automatic disconnection device 5 to slide on the frame 1, thereby pulling the fourth pull rope 504 to lift the counterweight device 4. When the patient raises their legs to a certain height, they can hold the position for a period of time or immediately relax and lower them slowly. At this time, the counterweight device 4 will pull the patient's legs to the side of the body back to the initial position through the fourth pull rope 504, the automatic disconnection device 5, and the first pull ropes 203 in sequence. Repeating the leg raising and relaxing process can be used for individual lower limb training.

[0037] In the embodiments of this application, reference is made to the appendix. Figure 10 As shown, the counterweight device 4 includes a counterweight frame 401 and several counterweight blocks 402. The counterweight frame 401 is connected to the fourth pull rope 504. The counterweight blocks 402 are circular with a hole in the middle and are fitted onto the counterweight frame 401. During training, the weight of the entire counterweight device 4 can be adjusted by increasing or decreasing the number of counterweight blocks 402, thereby adapting to the patient's needs for adjusting the training intensity and meeting the training needs of the patient at different stages.

[0038] In the embodiments of this application, reference is made to the appendix. Figures 9-12 As shown, the upper limb training mechanism 3 includes two pull rings 301 and two pull rope assemblies 302. One end of each pull rope assembly 302 is fixedly connected to the two pull rings 301, and the other end is fixedly connected to the counterweight device 4.

[0039] Specifically, the two pull rope assemblies 302 include a pull strap 3021 and a third pull rope 3022. The pull strap 3021 is a strip-shaped structure with a certain width. One end of the pull strap 3021 is fixedly connected to the pull ring 301, and the other end passes through a roller 3023 rotatably mounted on the frame 1 and is fixedly connected to the third pull rope 3022. The other end of the third pull rope 3022 is fixedly connected to the counterweight frame 401 on the counterweight device 4 through a roller 3024 rotatably mounted on the frame 1. The second pull rope 204 passes through the roller 3023, which is a roller that can connect two pull ropes simultaneously.

[0040] When performing upper limb training, the patient can choose to sit on the training chair 201 or stand. Then, the patient should firmly grasp the two pull rings 301 with both hands and slowly pull down the two pull rings 301. The two pull rings 301 move down, causing the pull strap 3021 to move on the roller 1 3023. The movement of the pull strap 3021 causes the third pull rope 3022 to move on the roller 2 3024. In turn, the third pull rope 3022 lifts the counterweight frame 401. After the lower arm is pulled to a certain position, hold the position for a few seconds or immediately and slowly release the pulling force. At this time, the counterweight device 4 will then move the patient's arm up and back to the initial state through the third pull rope 3022 and the pull strap 3021. Repeatedly pulling down and releasing the pull rings 301 can achieve upper limb training.

[0041] In this embodiment of the application, by the cooperation of the automatic disconnection device 5 and the automatic disconnection device 6, the lower limb exercise circuit can be automatically disconnected, and the upper limb exercise circuit can be automatically connected to another lower limb exercise circuit, thereby realizing coordinated switching training of upper and lower limbs on the same set of equipment.

[0042] For details, please refer to the appendix. Figures 13-15As shown, the automatic disconnection device 26 includes two bases 601, an electromagnet 602, and two opposite magnets 603. The surfaces of the two bases 601 are coated with an insulating layer and are respectively mounted on the pull strap 3021. The electromagnet 602 is connected to the end of the second pull rope 204. The end of the second pull rope 204 is slidably mounted above the pull strap 3021 via a fixing clamp 2041. The fixing clamp 2041 is slidably engaged in a groove 101 on the frame 1. The end of the second pull rope 204 is fixedly connected to the fixing clamp 2041. When the second pull rope 204 moves, it will pull the fixing clamp 2041 to slide in the groove 101 on the frame 1.

[0043] Two different magnets 603 are respectively slidably locked in the mounting holes 6011 in the two bases 601 by corresponding springs, and are used in conjunction with the two ends of the electromagnet 602.

[0044] In the initial state, electromagnet 602 is located between the two bases 601, and its length is less than the distance between the two bases 601. When not connected, it will not affect the movement of the pull strap 3021. When it is necessary to connect the pull strap 3021 and the second pull rope 204, electromagnet 602 is energized, and its two ends will generate N pole and S pole respectively. The N pole and S pole will attract the two opposite magnets 603 located in the mounting hole 6011 and stretch the spring 6031 (the surface of the spring 6031 is coated with an insulating layer). At this time, the two opposite magnets 603 are still in the mounting hole 6011, thereby achieving the purpose of automatic connection between electromagnet 602 and the two bases 601, and realizing the automatic fixed connection between the second pull rope 204 and the pull strap 3021. When it is necessary to disconnect, electromagnet 602 is de-energized, the magnetic force at both ends of electromagnet 602 disappears, and the two opposite magnets 603 are pulled back to the initial position under the action of spring 6031.

[0045] To facilitate the easy connection between the electromagnet 602 and the two bases 601, two motors 102 are installed on the frame 1. The two motors 102 are slidably mounted on the frame 1 and are respectively connected to two pull straps 3021. When the pull straps 3021 move, they will drive the motors 102 to move on the frame 1. When it is necessary to connect the pull straps 3021 and the second pull rope 204, the motors 102 can be controlled to wind up the pull straps 3021, so that the electromagnet 602 on the pull straps 3021 corresponds to the two bases 601, which is convenient for energizing and adsorption connection.

[0046] For details, please refer to the appendix. Figure 7 Figure 8As shown, the automatic disconnection device 5 includes an L-shaped slider 501 and a fixing block 502. The L-shaped slider 501 is slidably mounted on the frame 1 via a groove 101, and its end is fixedly connected to the first pull rope 203. A magnetic column is embedded in the L-shaped slider 501. The fixing block 502 is slidably mounted on the frame 1, and an electromagnet 503 is fixedly mounted inside it, working in conjunction with the magnetic column. The end of the fixing block 502 is fixedly connected to the counterweight device 4 via a fourth pull rope 504. The fourth pull rope 504 is connected to the counterweight device 4 via one of the rollers 3024 rotatably mounted on the frame 1. The roller 3024 can connect two pull ropes simultaneously.

[0047] When it is necessary to connect the L-shaped slider 501 and the fixing block 502, the L-shaped slider 501 is manually inserted into the fixing block 502, and the electromagnet 503 is energized to generate magnetic poles at its end. This causes the L-shaped slider 501 to be attracted upwards through the magnetic post, thus locking the electromagnet 503 and the magnetic post inside the L-shaped slider 501 together. At this time, the L-shaped slider 501 is still located in the slide groove 101. When it is necessary to disconnect, the electromagnet 503 is de-energized, and the L-shaped slider 501 returns to its initial position under its own weight.

[0048] When upper and lower limb coordination training is required, firstly, the first pull rope 203 and the fourth pull rope 504 are automatically disconnected using the automatic disconnection device 5. Then, the second pull rope 3021 and the second pull rope 204 are automatically connected using the automatic disconnection device 6. Next, the person sits on the training chair 201 and fixes their legs in the two leg fixation devices 202. Then, the two pull rings 301 are pulled down, which moves the pull rope 3021. The movement of the pull rope 3021 moves the second pull rope 204 upward, thereby raising the patient's legs. At the same time, the pull strap 3021 also pulls the third pull rope 3022 to move on the roller 3024, thereby lifting the counterweight frame 401 through the third pull rope 3022. After the lower arm is pulled to a certain position, hold the position for a few seconds or immediately and slowly relax the pulling force. At this time, the counterweight device 4 will drive the patient's arm to move up and return to the initial state through the third pull rope 3022 and the pull strap 3021 in sequence, while driving the two leg fixation devices 202 to fall down. By repeatedly pulling down and relaxing the pull ring 301, coordinated training of the upper and lower limbs can be achieved.

[0049] The preferred embodiment of the method of using a training device for patients with muscular atrophy is as follows: S1. When upper limb training needs to be performed separately.

[0050] Using the automatic disconnection device 26, the pull strap 3021 and the second pull rope 204 are automatically disconnected. The patient can choose to sit on the training chair 201 or stand for training. Then, the patient holds the two pull rings 301 tightly with both hands and slowly pulls down the two pull rings 301. The two pull rings 301 move down, causing the pull strap 3021 to move on the roller 1 3023. The movement of the pull strap 3021 causes the third pull rope 3022 to move on the roller 2 3024. Then, the counterweight frame 401 is lifted by the third pull rope 3022. After the lower arm is pulled to a certain position, hold the position for a few seconds or immediately and slowly release the pulling force. At this time, the counterweight device 4 will then move the patient's arm up and back to the initial state through the third pull rope 3022 and the pull strap 3021 in sequence. By repeatedly pulling down and releasing the pull rings 301, upper limb training can be achieved.

[0051] S2. When lower limb training needs to be performed separately.

[0052] The automatic disconnection device 5 automatically connects the first pull rope 203 and the fourth pull rope 504. The patient sits on the training chair 201 and places both legs in the two leg fixation devices 202 respectively. The legs are then fixed to the two leg fixation devices 202 with straps. The patient then slowly raises their legs. The two leg fixation devices 202 drive the two first pull ropes 203 to move outward relative to the body. The two first pull ropes 203 drive the automatic disconnection device 5 to slide on the frame 1, thereby pulling the fourth pull rope 504 to lift the counterweight device 4. When the patient raises their legs to a certain height, they can hold the position for a period of time or immediately relax and lower them slowly. At this time, the counterweight device 4 will pull the patient's legs to the side of the body back to the initial position through the fourth pull rope 504, the automatic disconnection device 5, and the first pull rope 203 in sequence. Repeated leg raising and relaxing can be used for lower limb individual training.

[0053] S3. When upper and lower limb coordinated training is required, firstly, the automatic disconnection device 5 is used to automatically disconnect the first pull rope 203 and the fourth pull rope 504. Then, the automatic disconnection device 6 is used to automatically connect the pull strap 3021 and the second pull rope 204. Next, the person sits on the training chair 201 and fixes their legs in the two leg fixation devices 202. Then, the two pull rings 301 are pulled down, which moves the pull strap 3021. The movement of the pull strap 3021 moves the second pull rope 204 upward, thereby moving the patient's legs. When the arm is lifted, the strap 3021 pulls the third rope 3022 to move on the roller 3024, thereby lifting the counterweight frame 401 through the third rope 3022. After the lower arm is pulled to a certain position, hold the position for a few seconds or immediately and slowly release the pulling force. At this time, the counterweight device 4 will drive the patient's arm to move up and return to the initial state through the third rope 3022 and the strap 3021 in sequence, while driving the two leg fixation devices 202 to fall down. By repeatedly pulling down and releasing the pull ring 301, coordinated training of the upper and lower limbs can be achieved.

[0054] Example 2: See attached document Figure 16 As shown, based on Embodiment 1, considering that during rehabilitation training using the muscle atrophy patient training equipment of Embodiment 1, the pull ropes that are not involved in the training may fold due to the reciprocating up and down movement of the counterweight device 4 during the training process. The folded pull ropes are easy to get tangled with the pull ropes involved in the training or affect the reciprocating movement of the counterweight device 4. Therefore, this embodiment designs an automatic winding device 8 to automatically wind up the pull ropes that are not involved in the training and avoid them affecting the training.

[0055] This embodiment is provided with two automatic winding devices 8. One end of each automatic winding device 8 is connected to two third pull ropes 3022 and two fourth pull ropes 504 respectively, and the other end is connected to the counterweight device 4, so as to facilitate the winding of the third pull ropes 3022 and the fourth pull ropes 504 respectively.

[0056] For details, please refer to the appendix. Figure 10 , Figure 15 As shown, the automatic winding device 8 includes a winding body 801, a torsion spring 802, and a slider 803. The lower end of the winding body 801 is fixedly connected to the counterweight device 4. The torsion spring 802 is disposed in the inner cavity of the winding body 801, with one end fixedly connected to the inner wall of the winding body 801. The slider 803 is slidably disposed in the winding body 801, with one end fixedly connected to the torsion spring 802 and the other end fixedly connected to the third pull rope 3022 or the fourth pull rope 504.

[0057] The winding body 801 has a circular groove, and the slider 803 is slidably engaged in the circular groove. Under the action of the torsion spring 802, it can slide along the circular groove.

[0058] When the counterweight device 4 is not pulled up, the third rope 3022 and the fourth rope 504 are taut, and the torsion spring 802 is stretched. When performing upper and lower limb coordination training, the fourth rope 504 is not involved in the training. When the counterweight device 4 moves up, the fourth rope 504 will be wound into the winding body 801 under the action of the torsion spring 802 to avoid the fourth rope 504 folding and affecting the training. Similarly, when the third rope 3022 is not involved in the training, it will also be wound up.

[0059] Example 3: See attached document Figures 14-18 As shown, based on Embodiment 2, considering that patients may experience weakness during rehabilitation training, this could cause the counterweight device 4 to drop suddenly, potentially causing injury to the patient. Therefore, this embodiment includes a buffer device 7, which can buffer the counterweight device 4 in case of weakness, preventing the sudden and rapid drop of the counterweight device 4 from causing physical injury to the patient.

[0060] The buffer device 7 is fixedly installed on the frame 1 and located between the automatic winding device 8 and the counterweight device 4. It is used to buffer the downward-moving counterweight device 4. That is, the counterweight device 4 is fixedly connected to the automatic winding device 8 through the buffer device 7.

[0061] For details, please refer to the appendix. Figure 10 , Figures 16-17 As shown, the buffer device 7 includes a first buffer cylinder 701, a second buffer cylinder 702, and a piston rod 703. The first buffer cylinder 701 is a cylindrical structure, and its inner cavity is filled with liquid. The second buffer cylinder 702 has the same structure as the first buffer cylinder 701 and is concentrically fixed inside the first buffer cylinder 701. At the lower end of the second buffer cylinder 702, there are a liquid outlet 7021, a high-flow-rate check valve 7022, and a low-flow-rate check valve 7023, all communicating with its inner cavity. The high-flow-rate check valve 7022 and the low-flow-rate check valve 7023 have opposite flow directions. The piston rod 703 is movably inserted into the second buffer cylinder 702 for exchanging the liquid between the first buffer cylinder 701 and the second buffer cylinder 702. The other end is fixedly connected to the winding body 801. The piston rod 703 is engaged within the second buffer cylinder 702.

[0062] When the third pull rope 3022 and the two fourth pull ropes 504 pull the winding body 801 upward, they will drive the piston rod 703 upward in the buffer cylinder 2 702, thereby drawing the liquid in the buffer cylinder 1 701 from the outlet 7021 and the high-flow-rate one-way valve 7022 into the buffer cylinder 2 702. At this time, because the liquid inlet of the outlet 7021 and the high-flow-rate one-way valve 7022 is large, the resistance is small. When the counterweight device 4 falls back, it will pull the piston rod 703 downward in the buffer cylinder 2 702, thereby pushing the liquid in the buffer cylinder 2 702 out from the outlet 7021 and the low-flow-rate one-way valve 7023, so that it re-enters the buffer cylinder 1 701. At this time, because the liquid outlet of the outlet 7021 and the low-flow-rate one-way valve 7023 is large, the resistance is large, which will cause the counterweight device 4 to fall back slowly.

[0063] The process of this invention, which provides a training device for patients with muscular atrophy, includes: S1. When upper limb training needs to be performed separately.

[0064] The automatic disconnection device 26 automatically disconnects the pull strap 3021 and the second pull rope 204. The patient can choose to sit on the training chair 201 or stand for training. Then, the patient firmly grasps the two pull rings 301 with both hands and slowly pulls down the two pull rings 301. The downward movement of the two pull rings 301 causes the pull strap 3021 to move on the roller 1 3023. The movement of the pull strap 3021 causes the third pull rope 3022 to move on the roller 2 3024. In turn, the third pull rope 3022 lifts the winding body 801, and at the same time, it causes the piston rod 703 to move upward in the buffer cylinder 2 702. In turn, the liquid in the buffer cylinder 1 701 is drawn into the buffer cylinder 2 702 from the outlet 7021 and the high-flow one-way valve 7022. Inside, when the piston rod 703 reaches the top of the second buffer cylinder 702, the counterweight frame 401 is lifted. After the arm is pulled to a certain position, hold the position for a few seconds or immediately and slowly release the downward force. At this time, the counterweight device 4 pulls the piston rod 703 down in the second buffer cylinder 702, thereby pushing the liquid in the second buffer cylinder 702 out of the outlet 7021 and the small flow one-way valve 7023, so that it re-enters the first buffer cylinder 701 to slow down the falling speed of the counterweight device 4. And by pulling the third pull rope 3022 and the pull belt 3021 in sequence through the retracting body 801, the patient's arm is moved up and returned to the initial state. By repeatedly pulling down and releasing the pull ring 301, upper limb training can be achieved.

[0065] S2. When lower limb training needs to be performed separately.

[0066] The automatic disconnection device 5 automatically connects the first pull rope 203 and the fourth pull rope 504. The patient sits on the training chair 201 with both legs placed in the two leg fixation devices 202 and secured to them with straps. The patient then slowly lifts their legs, causing the two leg fixation devices 202 to move the two first pull ropes 203 outwards relative to the body. The two first pull ropes 203 cause the automatic disconnection device 5 to slide on the frame 1, which in turn pulls the fourth pull rope 504 on the roller 3024. This, in turn, lifts the winding body 801 via the fourth pull rope 504, simultaneously causing the piston rod 703 to move upwards within the buffer cylinder 702. This causes the liquid in the buffer cylinder 701 to flow from the outlet 7021 and the high-flow-rate tube. The piston rod 703 is drawn into the second buffer cylinder 702 through the valve 7022. When the piston rod 703 reaches the top of the second buffer cylinder 702, the counterweight frame 401 is lifted. After the patient raises their leg to a certain height, they can hold it for a period of time or immediately relax and fall slowly. At this time, the counterweight device 4 pulls the piston rod 703 down in the second buffer cylinder 702, thereby pushing the liquid in the second buffer cylinder 702 out of the outlet 7021 and the small flow one-way valve 7023, so that it re-enters the first buffer cylinder 701 to slow down the fall speed of the counterweight device 4. The fourth pull rope 504, the automatic disconnection device 5, and the first pull rope 203 are pulled by the retracting body 801 to move the patient's leg to the side of the body to the initial state. Repeated leg raising and relaxing can be used for lower limb individual training.

[0067] S3. When upper and lower limb coordinated training is required, firstly, the first pull rope 203 and the fourth pull rope 504 are automatically disconnected using the automatic disconnection device 1. Then, the second pull rope 3021 and the second pull rope 204 are automatically connected using the automatic disconnection device 2. Next, the person sits on the training chair 201 and fixes their legs in the two leg fixation devices 202. Then, the two pull rings 301 are pulled down, which moves the pull rope 3021. The movement of the pull rope 3021 moves the second pull rope 204 upward, thereby lifting the patient's legs. At the same time, the pull rope 3021 also pulls the third pull rope 3022 to move on the roller 2 3024, thereby lifting the winding body 801 through the third pull rope 3022. At the same time, the piston rod 703 moves upward in the buffer cylinder 2 702, thereby discharging the liquid in the buffer cylinder 1 701 from the outlet. The nozzle 7021 and the high-flow one-way valve 7022 are drawn into the second buffer cylinder 702. When the piston rod 703 reaches the top of the second buffer cylinder 702, the counterweight frame 401 is lifted. After the arm is pulled to a certain position, hold the position for a few seconds or immediately and slowly release the downward force. At this time, the counterweight device 4 pulls the piston rod 703 down in the second buffer cylinder 702, thereby pushing the liquid in the second buffer cylinder 702 out of the outlet nozzle 7021 and the low-flow one-way valve 7023, so that it re-enters the first buffer cylinder 701 to slow down the falling speed of the counterweight device 4. By retracting the main body 801, the third pull rope 3022 and the pull strap 3021 are pulled in sequence to move the patient's arm up and return to the initial state. At the same time, the two leg fixation devices 202 are lowered. By repeatedly pulling down and releasing the pull ring 301, the coordinated training of the upper and lower limbs can be achieved.
