Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical rehabilitation equipment, in particular to a forearm rehabilitation device for hemodialysis patients, a rehabilitation system and application thereof in forearm rehabilitation of hemodialysis patients. BACKGROUND

[0002] After a period of time, the forearm of the hemodialysis patient receiving puncture of the arm (the side with a fistula) will mostly cause vascular injury and scarring due to changes in hemodynamics. In addition, muscle nutrition is lost due to dialysis, which affects the appearance of the arm and even the vascular dialysis access. These are all problems that dialysis patients are anxious about.

[0003] Shock waves are mechanical waves that can enter human tissues and produce mechanical stress effects and cavitation effects, thereby inducing the formation of new blood vessels: shock waves can stimulate the release of vascular endothelial growth factor and promote the generation of new capillaries, thereby significantly improving blood supply and nutrition at the lesion site. Shock waves can also stimulate stem cell activation and recruitment: attract and activate mesenchymal stem cells to gather at the injury site, differentiate into the required tissue cells, and promote tissue regeneration. Currently, shock wave products have a wide range of uses, in addition to being widely used in the treatment of painful diseases, they are also used for burns, skin ulcers, blood vessel patency, varicose veins, etc. According to the performance characteristics of the above shock waves and the application environment of the shock waves, relevant technical personnel have used the principle of shock waves to make shock wave massage devices for hemodialysis patients to rehabilitate the forearms before dialysis and prevent lesions.

[0004] However, the existing medical shock waves for dialysis forearm rehabilitation are mainly focused shock waves and divergent shock waves. The focal point diameter of the focused shock wave is generally not more than 20mm, although the penetration depth can reach more than 100mm, but the action area is small; the action area of the divergent shock wave is larger, but it only acts on the surface layer, and the depth of penetration into the tissue is limited, and it is still mainly a mode of knocking the skin, which is not conducive to the maintenance of the vascular access. The muscle deformation, vascular sclerosis, etc. of the forearm of the dialysis patient are basically the entire forearm, and the depth is not uniform, and the existing shock waves with small focal points and divergent shock waves are obviously difficult to operate and fully act, resulting in poor rehabilitation effect. For example, using the existing focused shock wave, triggering 300 times at each point, and switching dozens of points to cover the affected area, resulting in a long treatment time, not only low efficiency, but also long-term shock wave action will cause discomfort to the patient, increase the patient's rehabilitation pain, and seriously affect the forearm rehabilitation effect.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0024] One of the objectives of the present application is to provide a forearm rehabilitation device for hemodialysis patients, which performs forearm massage by using converging shock waves that neither have a very concentrated focal point nor are completely divergent, has a large acting area at a single point, a wide acting depth adjustment range, and can play an efficient and reliable rehabilitation role for different muscle deformations and blood vessel hardening of the forearms of dialysis patients, thereby improving the rehabilitation experience of patients while improving the rehabilitation effect and efficiency.

[0025] Another objective of the present application is to provide a rehabilitation system comprising the above-mentioned forearm rehabilitation device for hemodialysis patients.

[0026] The application further provides the application of the forearm rehabilitation device for hemodialysis patients to forearm rehabilitation of hemodialysis patients.

[0027] In order to make the above-mentioned purposes, features and advantages of the application more obvious and easy to understand, the application will be further described in detail below with reference to the drawings and specific embodiments.

[0028] Embodiment 1 As shown in Figure 1 , Figure 4 , Figure 6 and Figure 7 , the embodiment provides a forearm rehabilitation device 100 for hemodialysis patients, which comprises a tubular shock wave assembly 1, a first water tank 2 and a second water tank 3, wherein the tubular shock wave assembly 1 comprises a shock wave generating component and an elliptical cross-section vibration-conducting metal pipe 11, the axial ends of the vibration-conducting metal pipe 11 are respectively connected with the first water tank 2 and the second water tank 3 in a sealed manner, so that the first water tank 2, the inner cavity of the vibration-conducting metal pipe 11 and the second water tank 3 are connected to form a massage water tank for placing the forearm 4, and the massage water tank is used for containing water 5, when in use, the forearm 4 needing rehabilitation is immersed in the water 5 and extends into the vibration-conducting metal pipe 11, and the water 5 fills in the vibration-conducting metal pipe 11. The shock wave generating component comprises an inductor coil 12 for connecting an energy system, the inductor coil 12 is wound on the outer wall of the vibration-conducting metal pipe 11, the energy system can provide pulse electric energy to the inductor coil 12, the inductor coil 12 can convert the pulse electric energy into a pulse electromagnetic field and act on the vibration-conducting metal pipe 11, so as to push the water 5 in the vibration-conducting metal pipe 11 to move and generate mechanical shock waves, at this time, since the forearm 4 extends into the vibration-conducting metal pipe 11 and is immersed in the water 5, the mechanical shock waves generated by the movement of the water 5 can fully act on the outer peripheral surface of the forearm 4, so as to achieve the purpose of forearm rehabilitation of hemodialysis patients.

[0029] The shock wave converges in the vibration-conducting metal pipe 11, as shown in Figure 3 , the long axis 111 direction of the elliptical cross-section of the vibration-conducting metal pipe 11 extends horizontally along the transverse direction, and the short axis 112 direction of the elliptical cross-section of the vibration-conducting metal pipe 11 extends vertically along the longitudinal direction; based on this, in combination with Figure 3The shock wave arrow direction shown that the shock wave is relatively concentrated at both ends of the long axis 111, and the shock wave is relatively divergent in the remaining area. The overall axial vibration-conducting metal pipe 11 is preferably 120-200 mm long, which is suitable for the length of the forearm 4. During operation, the vibration-conducting metal pipe 11 is filled with water 5, the forearm 4 is inserted into the pipe, and the energy system connected to the inductor coil 12 is turned on. The forearm 4 will feel the pulse pressure of the shock wave, and the pressure at both ends of the long axis 111 is relatively large. After a certain number of shock wave massages, the arm is rotated, and the other positions of the arm are also subjected to force. The shock wave pulse on each surface of the arm is calculated at 1000 times, twice per second. The arm position can be rotated once in less than ten minutes, and a rotation basically covers the entire length of the forearm 4. The overall tubular shock wave assembly 1 adopts an elliptical tubular structure, which can concentrate the shock wave pressure at both ends of the long axis 111, and can avoid the problem that the maximum pressure on the forearm skeleton is enhanced due to the focus of the shock wave being concentrated at the center of the circle.

[0030] In some feasible embodiments, the inductor coil 12 is wound outside the vibration-conducting metal pipe 11 in one or more groups, depending on the power size. One group of coils belongs to one shock wave generating unit. Due to the long length and circumference of the vibration-conducting metal pipe 11, the power effect of one shock wave generating unit may not meet the rehabilitation requirements, so at least two groups of inductor coils 12 are generally wound axially on the inductor coil 12.

[0031] In some feasible embodiments, as shown in Figure 1 and Figure 2 The foregoing shock wave generating component further includes an inner insulating film layer 13 and an outer insulating film layer 14. The inner insulating film layer 13 is arranged between the inner circle of the inductor coil 12 and the outer wall of the vibration-conducting metal pipe 11. The inner insulating film layer 13 is tightly wrapped around the outer wall of the vibration-conducting metal pipe 11, and the inductor coil 12 is tightly wrapped outside the inner insulating film layer 13. The outer insulating film layer 14 is tightly wrapped on the outer surface of the inductor coil 12. The foregoing outer insulating film layer 14 and inner insulating film layer 13 are arranged in close contact with the outer circle surface and inner circle surface of the inductor coil 12, respectively, which can play an insulating protection role and avoid 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 protection role of insulating current and do not affect the generation of the pulse electromagnetic field after the inductor coil 12 is powered on.

[0032] 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.

[0033] In some feasible implementations, the aforementioned inner protective film layer 16 is a silicone film.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] In summary, the beneficial effects of the forearm rehabilitation device 100 for hemodialysis patients proposed in this invention are as follows: 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] Example 2 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.
