Description

Technical Field

[0001] This invention relates to the field of medical rehabilitation equipment technology, and in particular to a forearm rehabilitation device, rehabilitation system, and its application in forearm rehabilitation of hemodialysis patients. Background Technology

[0002] After a period of time, most hemodialysis patients experience vascular damage and scarring in the forearm (the side with the fistula) of the arm that underwent puncture due to changes in hemodynamics. In addition, dialysis causes muscle nutrient loss, which can affect the appearance of the arm in mild cases and, in severe cases, impair dialysis access. These are all sources of anxiety for dialysis patients.

[0003] Shockwaves are mechanical waves that can penetrate human tissues and generate mechanical stress and cavitation effects, thereby inducing angiogenesis. Shockwaves can stimulate the release of vascular endothelial growth factor and other factors, promoting the formation of new capillaries and significantly improving blood supply and nutrition to the affected area. Shockwaves can also stimulate stem cell activation and recruitment: attracting and activating mesenchymal stem cells to the damaged area, differentiating them into the required tissue cells, and promoting tissue regeneration. Currently, shockwave products have a wide range of applications, including the treatment of pain disorders, burns, skin ulcers, clearing blood vessels, and treating varicose veins. Based on the above-mentioned performance characteristics and application environments of shockwaves, some technicians have already used the principles of shockwaves to create shockwave massage devices for the forearm rehabilitation and disease prevention of uremia patients undergoing dialysis.

[0004] However, existing medical shockwave therapy for forearm rehabilitation in dialysis patients is mainly divided into focused shockwaves and divergent shockwaves. Focused shockwaves generally have a focal diameter of no more than 20mm, and although their penetration depth can reach over 100mm, their effective area is small. Divergent shockwaves, while having a larger effective area, only act on the surface layer, with limited tissue penetration, and their primary mode of action is tapping the skin, which is highly detrimental to vascular access maintenance. Muscle deformities and vascular sclerosis in dialysis patients' forearms are generally felt throughout the entire forearm, varying in depth. Existing shockwaves with their small focal points and divergent action are clearly difficult to operate and provide comprehensive coverage, resulting in poor rehabilitation outcomes. For example, using existing focused shockwaves, each point needs to be triggered 300 times, requiring dozens of points to fully cover the affected area. This leads to prolonged treatment time, low efficiency, and prolonged shockwave exposure can cause patient discomfort, increasing rehabilitation pain and severely impacting forearm rehabilitation outcomes. Summary of the Invention

[0005] The purpose of this invention is to provide a forearm rehabilitation device, rehabilitation system, and application for hemodialysis patients. It uses a converging shock wave that is neither highly concentrated nor completely divergent to massage the forearm. This not only provides a large area of ​​action at a single point but also a wide range of adjustable depth of action. It can effectively and reliably rehabilitate different levels of muscle deformation and arteriosclerosis in the forearm of dialysis patients, improving rehabilitation effect and efficiency while also enhancing the patient's rehabilitation experience, thus solving the problems existing in the prior art.

[0006] To achieve the above objectives, the present invention provides the following solution:

[0007] On one hand, the present invention provides a forearm rehabilitation device for hemodialysis patients, comprising a tubular shockwave assembly, a first water tank, and a second water tank, wherein the tubular shockwave assembly includes:

[0008] An elliptical cross-section guide metal tube is provided. The two ends of the guide metal tube are respectively sealed to the first water tank and the second water tank, so that the first water tank, the inner cavity of the guide metal tube and the second water tank are connected to form a massage water tank for the forearm to be placed. The inside of the guide metal tube is used for the forearm to be inserted.

[0009] The shock wave generating component includes an inductor coil for connecting to an energy system. The inductor coil is wound around the outer wall of the vibration-guiding metal tube. The energy system can provide pulsed electrical energy to the inductor coil, which can convert the pulsed electrical energy into a pulsed electromagnetic field and act on the vibration-guiding metal tube. The vibration of the vibration-guiding metal tube drives the water inside the tube to move, generating a shock wave that acts on the forearm surface.

[0010] In some embodiments, the major axis of the elliptical cross-section of the vibration-guiding metal tube extends horizontally in the transverse direction, and the minor axis of the elliptical cross-section of the vibration-guiding metal tube extends vertically in the longitudinal direction.

[0011] In some embodiments, the shock wave generating component further includes:

[0012] An inner insulating film layer is disposed between the inner coil of the inductor coil and the outer wall of the vibration-guiding metal tube;

[0013] An outer insulating film layer is applied to the outer surface of the inductor coil.

[0014] In some embodiments, the forearm rehabilitation device for hemodialysis patients further includes:

[0015] An outer protective layer covers the outer surface of the outer insulating film layer;

[0016] An inner protective film layer is disposed on the inner wall surface of the vibration-guiding metal tube;

[0017] A columnar outer casing is fitted around the outer periphery of the inner protective film layer.

[0018] In some embodiments, the inner protective film layer is a silicone film.

[0019] In some embodiments, a rubber sealing flange is provided at each of the two axial ends of the vibration guiding metal tube, and the two axial ends of the vibration guiding metal tube are respectively sealed to the first water tank and the second water tank through the rubber sealing flange.

[0020] In some embodiments, the first water tank is a trapezoidal water tank with a trapezoidal longitudinal section, wherein the smaller end of the trapezoidal water tank faces down and the larger end faces up, and the larger end of the trapezoidal water tank is open.

[0021] The second water tank has the same structure as the first water tank, and the second water tank and the first water tank are arranged symmetrically at both ends of the vibration guiding metal tube.

[0022] On the other hand, the present invention proposes a forearm rehabilitation system for hemodialysis patients, comprising a main unit cabinet, an energy system, and the forearm rehabilitation device for hemodialysis patients described in any one of the above-mentioned embodiments, wherein:

[0023] The front side of the main unit cabinet is equipped with a lifting frame, and the forearm rehabilitation device for hemodialysis patients is installed on the lifting frame. The lifting frame can adjust the height of the forearm rehabilitation device for hemodialysis patients.

[0024] The energy system is located inside the main unit cabinet. The energy system includes a capacitor and a high-voltage component electrically connected to the capacitor. The high-voltage component is used to provide power to the capacitor. The capacitor is electrically connected to the inductor coil. The capacitor discharge can provide pulsed electrical energy to the inductor coil.

[0025] In some embodiments, the forearm rehabilitation system for hemodialysis patients further includes a control terminal, the control terminal comprising:

[0026] A control system is installed inside the main unit cabinet and electrically connected to the capacitor. The control system is used to regulate the output parameters of the pulsed electrical energy. The output parameters include one or more combinations of waveform, amplitude, width and repetition frequency.

[0027] An operation panel is located on the top of the main unit cabinet and is electrically connected to the control system. The operation panel is equipped with operation keys for adjusting the output parameters.

[0028] Furthermore, the present invention also proposes the application of the forearm rehabilitation device for hemodialysis patients described in any of the above-mentioned claims in the forearm rehabilitation of hemodialysis patients.

[0029] The present invention achieves the following technical effects compared to the prior art:

[0030] 1. This invention uses a vibration-guiding metal tube with an elliptical cross-section to create shock waves that are neither focused nor divergent, but rather convergent towards the tube. This combines the advantages of both focused and divergent shock waves. On the one hand, it reduces rehabilitation time to a maximum of about twenty minutes per session, making rehabilitation much simpler and more convenient for patients. On the other hand, it avoids the problem of increased pain caused by concentrated shock waves putting excessive pressure on bones.

[0031] 2. The shock wave generated by this invention covers the entire axial and circumferential direction of the guiding metal tube, so that the entire arm can be covered by shock wave massage with each forearm rotation, thereby maximizing the efficiency of the shock wave and reducing the single rehabilitation time.

[0032] 3. Since the vibration-guiding metal tube is connected to the water tank, there is no other form of water bag that focuses the shock wave. The arm can be completely immersed in the water in the vibration-guiding metal tube, which couples well with the shock wave, maximizing the shock wave massage rehabilitation effect and further improving rehabilitation efficiency.

[0033] 4. This invention can be effectively and advantageously applied in the clinical application of arm rehabilitation and care for uremia patients, and can solve the confusion and difficulties that arm rehabilitation currently causes for doctors and patients. Attached Figure Description

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] One objective of this invention is to provide a forearm rehabilitation device for hemodialysis patients. This device uses a converging shockwave that is neither highly concentrated nor completely divergent to massage the forearm. It not only has a large area of ​​action at each point but also a wide range of adjustable depth of action. It can provide efficient and reliable rehabilitation for different levels of muscle deformation and arteriosclerosis in the forearm of dialysis patients, improving rehabilitation effect and efficiency while also enhancing the patient's rehabilitation experience, thus solving the problems existing in the prior art.

[0051] Another object of the present invention is to provide a rehabilitation system comprising the above-described forearm rehabilitation device for hemodialysis patients.

[0052] Another object of the present invention is to provide an application of the above-mentioned forearm rehabilitation device for hemodialysis patients in forearm rehabilitation of hemodialysis patients.

[0053] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0054] Example 1

[0055] like Figure 1 , Figure 4 , Figure 6 and Figure 7 As shown, this embodiment provides a forearm rehabilitation device 100 for hemodialysis patients, including a tubular shockwave assembly 1, a first water tank 2, and a second water tank 3. The tubular shockwave assembly 1 includes a shockwave generating component and a vibration-guiding metal tube 11 with an elliptical cross-section. The two axial ends of the vibration-guiding metal tube 11 are respectively sealed and connected to the first water tank 2 and the second water tank 3, so that the first water tank 2, the inner cavity of the vibration-guiding metal tube 11, and the second water tank 3 are connected to form a massage water tank for placing the forearm 4. The massage water tank is used to hold water 5. When in use, the forearm 4 that needs rehabilitation is immersed in the water 5 and extends into the vibration-guiding metal tube 11, and the water 5 fills the vibration-guiding metal tube 11. The shock wave generating component includes an inductor coil 12 for connecting to the energy system. The inductor coil 12 is wound around the outer wall of the vibration-guiding metal tube 11. The energy system can provide pulsed electrical energy to the inductor coil 12. The inductor coil 12 can convert the pulsed electrical energy into a pulsed electromagnetic field and act on the vibration-guiding metal tube 11. The vibration of the vibration-guiding metal tube 11 drives the water body 5 inside the vibration-guiding metal tube 11 to move, thereby generating a mechanical shock wave. At this time, since the forearm 4 extends into the vibration-guiding metal tube 11 and is immersed in the water body 5, the mechanical shock wave generated by the movement of the water body 5 will fully act on the outer peripheral surface of the forearm 4, thereby achieving the purpose of forearm rehabilitation for dialysis patients.

[0056] When the shock wave occurs, it converges within the vibration-guiding metal tube 11, such as... Figure 3As shown, the major axis 111 of the elliptical cross-section of the vibration-guiding metal tube 11 extends horizontally in the transverse direction, while the minor axis 112 of the elliptical cross-section of the vibration-guiding metal tube 11 extends vertically in the longitudinal direction; based on this, combined with Figure 3 As shown by the arrows indicating the direction of the shockwaves, the shockwaves are relatively concentrated at both ends of the long axis 111, while the shockwaves are relatively dispersed in other areas. The overall axial length of the guiding metal tube 11 is preferably 120mm~200mm, adapted to the length of the forearm 4. During operation, the guiding metal tube 11 is filled with water 5, and the forearm 4 is inserted into the tube. After the energy system connected to the inductor coil 12 is activated, the forearm 4 will feel the pulse pressure of the shockwaves. The pressure at both ends of the long axis 111 is relatively high. After a certain number of shockwave massages, rotating the arm allows other parts of the arm to also experience the pressure. Assuming 1000 shockwave pulses per side of the arm, or twice per second, the arm can be rotated once in less than ten minutes. One rotation can basically cover the entire length of the forearm 4, and the entire shockwave massage and rehabilitation process for the forearm 4 takes no more than twenty minutes. The tubular shockwave component 1 adopts an elliptical tubular structure, which concentrates the shockwave pressure at both ends of the long axis 111, avoiding the problem of the forearm bones experiencing maximum pressure and increased pain due to the shockwave focus being concentrated at the center.

[0057] In some feasible implementations, one or more sets of inductor coils 12 are wound around the outside of the vibration-guiding metal tube 11, depending on the power. One set of coils belongs to one shock wave generating unit. However, since the length and circumference of the vibration-guiding metal tube 11 are relatively long, the power effect of one shock wave generating unit may not meet the rehabilitation needs. Therefore, at least two sets of inductor coils 12 are generally wound along the axial direction on the inductor coil 12.

[0058] Some feasible implementation methods, such as Figure 1 and Figure 2 As shown, the aforementioned shock wave generating component also includes an inner insulating film layer 13 and an outer insulating film layer 14. The inner insulating film layer 13 is disposed between the inner coil of the inductor coil 12 and the outer wall of the vibration-guiding metal tube 11, tightly wrapping the outer wall of the vibration-guiding metal tube 11, while the inductor coil 12 is tightly wrapped around the outside of the inner insulating film layer 13. The outer insulating film layer 14 tightly covers the outer surface of the inductor coil 12. The outer insulating film layer 14 and the inner insulating film layer 13 are respectively arranged close to the outer and inner surfaces of the inductor coil 12, which can play an insulating protection role and prevent coil leakage during forearm rehabilitation. It should be noted that the outer insulating film layer 14 and the inner insulating film layer 13 only play a protective role in insulating current and do not affect the generation of pulsed electromagnetic fields by the inductor coil 12 after being energized.

[0059] In some feasible implementations, the forearm rehabilitation device 100 for hemodialysis patients further includes an outer protective layer 15, an inner protective film layer 16, and a columnar outer casing 17. The outer protective layer 15 tightly covers the outer surface of the aforementioned outer insulating film layer 14, and the two can be reinforced and connected by an insulating adhesive layer. The inner protective film layer 16 is disposed on the inner wall surface of the vibration-guiding metal tube 11. As a protective layer for the vibration-guiding metal tube 11, the inner protective film layer 16 can be fixed to the inner wall surface of the vibration-guiding metal tube 11 by spraying, attaching, or other methods. On the one hand, it prevents the inner wall of the vibration-guiding metal tube 11 from rusting in the water body 5, and on the other hand, it protects the forearm from damage. The columnar outer casing 17 is made of waterproof material, such as a plastic shell or a metal shell. It is fitted around the outer periphery of the inner protective film layer 16, and its two ends are respectively connected to the first water tank 2 and the second water tank 3. The connection methods include, but are not limited to, welding and bolt connection. The columnar outer casing 17 serves as the outer protective shell of the entire shock wave generating component, providing both aesthetic appeal and double-layer protection.

[0060] In some feasible implementations, the aforementioned inner protective film layer 16 is a silicone film.

[0061] Some feasible implementation methods, such as Figure 1 and Figure 2 As shown, a waterproof and insulating rubber sealing flange 18 is provided at each of the axial ends of the vibration-guiding metal tube 11. The axial ends of the vibration-guiding metal tube 11 are respectively sealed to the first water tank 2 and the second water tank 3 through the rubber sealing flanges 18. Specifically, the inner rings of the two rubber sealing flanges 18 are tightly fitted onto the outer walls of both ends of the vibration-guiding metal tube 11, and the outer rings of the two rubber sealing flanges 18 are respectively sealed to the corresponding water tanks through multiple flange connecting bolts 19, and the flange connecting bolts 19 on each rubber sealing flange 18 are arranged along the circumference of the rubber sealing flange 18. The rubber sealing flanges 18 can ensure the sealing of the connection between the vibration-guiding metal tube 11 and the first water tank 2 and the second water tank 3, while isolating the inductor coil 12 and the water body 5, so as to ensure the safety during the shockwave massage rehabilitation process.

[0062] In some feasible implementations, the first water tank 2 and the second water tank 3 are preferably made of stainless steel or other waterproof materials.

[0063] Some feasible implementation methods, such as Figure 1 , Figure 4 and Figure 6 As shown, the first water tank 2 is preferably a trapezoidal water tank with a trapezoidal longitudinal section. The smaller end of the trapezoidal water tank faces downward and the larger end faces upward, and the larger end of the trapezoidal water tank is open to facilitate the insertion or removal of the forearm 4 from the water tank. Figure 1As shown, the longitudinal section of the first water tank 2 is preferably a right-angled trapezoid. A water passage hole is opened on the right-angled side of the right-angled trapezoid. The first water tank 2 is connected to the shaft end of the tubular shock wave assembly 1 through the right-angled side and is connected to the inside of the vibration guiding metal tube 11 of the tubular shock wave assembly 1 through the water passage hole.

[0064] The second water tank 3 has the same structure as the first water tank 2, and the second water tank 3 and the first water tank 2 are symmetrically arranged at both ends of the vibration guiding metal tube 11.

[0065] In some feasible implementations, the bottoms of the first water tank 2 and the second water tank 3 are respectively connected to a first water pipe 21 and a second water pipe 31, both of which are bent pipe structures. The first water tank 2 can be connected to a water system 800 via the first water pipe 21. A water pump can be installed on the first water pipe 21, which can pump water stored in the water system 800 into the first water tank 2, or drain the water from the first water tank 2 after the shockwave massage. Correspondingly, the second water tank 3 can be connected to the water system 800 via the second water pipe 31, which can be equipped with a water pump. The water pump can pump water stored in the water system 800 into the second water tank 3, or drain the water from the second water tank 3 after the shockwave massage.

[0066] The water system 800 may specifically include a water tank. Valves are also provided on the first water pipe 21 and the second water pipe 31 to close the first water pipe 21 and the second water pipe 31 after the water tank is filled with water, so as to prevent water leakage and ensure the shock wave massage effect.

[0067] The aforementioned forearm rehabilitation device 100 for hemodialysis patients is mainly used for forearm rehabilitation in hemodialysis patients. For example... Figure 8 As shown, the forearm 4 is placed in a massage water tank filled with water and inserted into the vibration-guided metal tube 11. The aforementioned energy system is activated, providing pulsed electrical energy to the inductor coil 12. The inductor coil 12 converts the pulsed electrical energy into a pulsed electromagnetic field, which acts on the vibration-guided metal tube 11. The vibration of the vibration-guided metal tube 11 drives the water 5 inside the tube, thereby generating a mechanical shock wave that applies pulsed pressure to the forearm 4. Because the cross-section of the vibration-guided metal tube 11 is elliptical, the pressure field within it is uneven. The pressure is more concentrated and stronger at both ends of the major axis of the ellipse, while the pressure at the top and bottom is relatively weaker. By making the pressure field distribution within the vibration-guided metal tube 11 uneven, the puncture site of the forearm 4 can be aligned with both ends of the major axis 111, achieving more frequent and higher-intensity massage at the puncture site, while the massage frequency and intensity of other parts of the forearm 4 are relatively less. This achieves comprehensive massage rehabilitation of the forearm 4 with adaptive shock wave massage intensity. While ensuring the recovery effect of the puncture site, it can avoid focusing the impact pressure on the center, thereby avoiding painful stimulation to the bone.

[0068] Electromagnetic shock waves are high-energy mechanical waves generated by the discharge of a high-voltage capacitor onto an inductor coil, producing a pulsed magnetic field that drives the vibration of a metal tube. These pressure pulses can penetrate the skin and enter the body's tissues. The basic working principle of the shock wave forearm massage water tank used for dialysis patient rehabilitation is essentially the same as that of extracorporeal shock wave lithotripters and focused shock wave therapy devices, and will not be elaborated upon here.

[0069] In summary, the beneficial effects of the forearm rehabilitation device 100 for hemodialysis patients proposed in this invention are as follows:

[0070] 1. This invention uses a vibration-guiding metal tube with an elliptical cross-section to create shock waves that are neither focused nor divergent, but rather convergent towards the tube. This combines the advantages of both focused and divergent shock waves. On the one hand, it reduces rehabilitation time to a maximum of about twenty minutes per session, making rehabilitation much simpler and more convenient for patients. On the other hand, it avoids the problem of increased pain caused by concentrated shock waves putting excessive pressure on bones.

[0071] 2. The shock wave generated by this invention covers the entire axial and circumferential direction of the guiding metal tube, so that the entire arm can be covered by shock wave massage with each forearm rotation, thereby maximizing the efficiency of the shock wave and reducing the single rehabilitation time.

[0072] 3. Since the vibration-guiding metal tube is connected to the water tank, there is no other form of water bag that focuses the shock wave. The arm can be completely immersed in the water in the vibration-guiding metal tube, which couples well with the shock wave, maximizing the shock wave massage rehabilitation effect and further improving rehabilitation efficiency.

[0073] 4. This invention can be effectively and advantageously applied in the clinical application of arm rehabilitation and care for uremia patients, and can solve the confusion and difficulties that arm rehabilitation currently causes for doctors and patients.

[0074] Example 2

[0075] like Figure 4 , Figure 6 and Figure 7As shown, this embodiment proposes a forearm rehabilitation system 200 for hemodialysis patients, including a main unit cabinet 300, an energy system, and the forearm rehabilitation device 100 for hemodialysis patients of Embodiment 1. A lifting frame 301 is mounted on the front side of the main unit cabinet 300, and the forearm rehabilitation device 100 for hemodialysis patients is mounted on the lifting frame 301. The lifting frame 301 can adjust the height of the forearm rehabilitation device 100 for hemodialysis patients relative to the main unit cabinet 300 to accommodate patients of different heights. The energy system is set inside the main unit cabinet 300. The energy system includes a capacitor 400 and a high-voltage component 500 electrically connected to the capacitor 400. The high-voltage component 500 is used to provide power to the capacitor 400. The capacitor 400 is electrically connected to an inductor coil 12, and the discharge of the capacitor 400 can provide pulsed electrical energy to the inductor coil 12.

[0076] The lead connector of the inductor coil 12 passes through the outer insulating film layer 14, the outer protective layer 15 and the columnar outer casing 17, then passes through the side wall of the main unit cabinet 300 and is electrically connected to the capacitor 400.

[0077] In some feasible implementations, the forearm rehabilitation system 200 for hemodialysis patients also includes a control terminal, which comprises a control system 600 and an operation screen 700. The control system 600 is located inside the main unit cabinet 300 and electrically connected to the capacitor 400. The control system 600 is used to regulate the output parameters of pulsed electrical energy, including one or more combinations of waveform, amplitude, width, and repetition frequency. The operation screen 700 is located on the top of the main unit cabinet 300 and electrically connected to the control system 600. The operation screen 700 is equipped with operation keys for regulating the output parameters. Both the operation screen 700 and the control system 600 are mature product technologies and will not be described in detail further.

[0078] The energy level of the high-voltage component 500 can be controlled by the control system 600. The high-voltage component 500 is a high-voltage device that can be composed of a transformer, voltage regulator, etc. Preferably, the high-voltage component 500 uses a high-frequency power supply, which can reduce the size and make the performance more reliable.

[0079] The aforementioned capacitor 400 and control system are all mature existing technologies, and their specific structures and working principles will not be described in detail here.

[0080] The main unit enclosure 300 may also be equipped with the water system 800 described in Embodiment 1, which is installed on the inner bottom plate of the main unit enclosure 300. For example... Figure 7 As shown, the control system 600, capacitor 400, high-voltage component 500 and water system 800 are distributed from top to bottom within the main unit cabinet 300.

[0081] The main unit enclosure 300 is preferably made of insulating material. For easy equipment movement, casters can also be installed at the bottom of the main unit enclosure 300. Figure 4 , Figure 6 and Figure 7 As shown, the main unit cabinet 300 is equipped with one omnidirectional wheel at the front end and two omnidirectional wheels symmetrically at the rear end.

[0082] like Figure 7 As shown, a lifting drive 302 is installed inside the main unit cabinet 300. A lifting cavity is opened on the front side of the main unit cabinet 300. The lifting frame 301 is located on the front side of the main unit cabinet 300. The rear end of the lifting frame 301 passes through the lifting cavity and is connected to the lifting drive 302. The forearm rehabilitation device 100 for hemodialysis patients is fixed on the lifting frame 301. Specifically, the first water tank 2 and the second water tank 3 can be fixed to the lifting frame 301 with bolts. The lifting drive 302 includes, but is not limited to, vertically arranged linear drive mechanisms such as cylinders, hydraulic cylinders, and electric slides to drive the forearm rehabilitation device 100 for hemodialysis patients to move up and down within the lifting cavity. The control switch of the lifting drive 302 is configured on the operation panel 700, allowing patients to flexibly adjust the height of the forearm rehabilitation device 100 for hemodialysis patients according to their needs.

[0083] Furthermore, in order to improve the dustproof performance of the main unit cabinet 300, a foldable lifting sealing curtain can be configured at the lifting cavity opening. The rear end of the lifting frame 301 is fixed in the middle of the lifting sealing curtain. The lifting sealing curtain is in a pleated state and has sufficient folding allowance to meet the lifting adjustment requirements of the lifting frame 301.

[0084] By installing a forearm rehabilitation device 100 for hemodialysis patients on a lifting frame 301, the forearm rehabilitation needs of patients of different heights can be met.

[0085] like Figure 8 As shown, the forearm rehabilitation system 200 for hemodialysis patients is also equipped with a seat, allowing patients to sit and receive massage rehabilitation, ensuring comfort during the rehabilitation process.

[0086] like Figure 8 As shown, dialysis is usually performed on the left forearm. If the patient is on their right arm, they can sit facing the opposite direction and still use the dialysis device.
