Abstract
Description
Technical Field
[0001] This application relates to the field of medical treatment equipment technology, and in particular to an air wave hot and cold compress rapid switching therapy device. Background Technology
[0002] Air wave therapy, also known as circulatory pressure therapy, mainly works by repeatedly inflating and deflating multi-chamber airbags in sequence, creating circulatory pressure on the limbs and tissues. It applies uniform and orderly compression to the distal parts of the limbs, promoting blood and lymph flow and improving microcirculation. It also accelerates the return of tissue fluid to the limbs, helps prevent thrombosis, prevents limb edema, and can directly or indirectly treat many diseases related to blood and lymphatic circulation.
[0003] Most of the air wave pressure therapy devices currently in use consist of two parts: a main unit equipped with an air pump and inflatable air bags. One air pump supplies air to all the inflatable air bags, and the air pump and the inflatable air bags are connected by a long inflation tube.
[0004] Hot and cold compress therapy is a physical therapy that uses the circulation of cold and hot media to act on the human body. It helps to reduce swelling and pain, lower energy metabolism, reduce lactic acid accumulation in tissues, reduce edema and lower intra-tissue pressure; it effectively reduces tissue damage and protein destruction, and promotes the recovery of nerve cell structure and function.
[0005] Regarding the aforementioned technologies, existing air wave pressure therapy devices typically lack the function of hot and cold compress cyclic therapy and cannot provide a wide range of air wave pressure therapy options, thus requiring improvement. Summary of the Invention
[0006] To facilitate hot and cold compress therapy and improve patients' medical experience and treatment outcomes, this application provides an air wave hot and cold compress rapid switching therapy device.
[0007] The air wave hot and cold compress rapid switching therapeutic device provided in this application adopts the following technical solution:
[0008] An air wave hot and cold compress rapid switching therapy device includes a control box, an air wave pressure component, a hot and cold compress circulation component, and a water tank. The air wave pressure component and the hot and cold compress circulation component are both mounted on the control box. The air wave pressure component is used to apply pressure therapy to the patient's limbs, and the hot and cold compress circulation component is used to apply cold or hot compresses to the patient's limbs.
[0009] The water storage tank has an opening and forms a water storage cavity. The control box is located on the side of the water storage tank near the opening and is connected to the water storage tank.
[0010] The hot and cold compress circulation assembly includes an inlet pipe, a water pump, and a return pipe. One end of the inlet pipe is located in the water storage chamber, and the other end is used to connect to an external inflatable airbag. The water pump is located on the inlet pipe and inside the control box. One end of the return pipe is located in the water storage chamber, and the other end is used to connect to an external inflatable airbag.
[0011] By adopting the above technical solution, when pressure therapy is required for patients, the air wave pressure component can be connected to an external inflatable airbag, and the air wave pressure component can inflate and deflate the inflatable airbag to achieve pressure therapy for patients.
[0012] When patients need to receive hot or cold compress treatment, cold or hot water is added to the water tank according to the user's needs (cold water for cold compresses, hot water for hot compresses). Then, the water pump is run using the control box, and the water in the water tank is fed into the external inflatable airbag through the inlet pipe, thereby achieving cold or hot compresses and improving the patient's medical experience and treatment effect.
[0013] During hot and cold compress therapy (taking hot compress as an example), the hot water inside the inflatable bladder transfers heat to the body. The water temperature inside the bladder gradually decreases, and this temperature change affects the treatment effect. At this point, the valve on the return water pipe can be opened, and the inflatable bladder can be pressed to allow the cooler water to flow back into the storage tank. Then, the water pump can be controlled to deliver the warmer hot water from the storage tank to the inflatable bladder to continue the hot compress treatment.
[0014] Preferably, the air wave pressure assembly includes an air pump and an air pipe, the air pump is disposed in the control box and connected to the air pipe, and the air pipe is connected to an external inflatable airbag.
[0015] By adopting the above technical solution, the air pump provides power to the air, and the air is transported along the air tube to the inflatable airbag, thereby realizing the inflation and deflation of the airbag and completing the air wave pressure therapy for the patient.
[0016] Preferably, the air pipe is further provided with a heater, which is used to heat the fluid in the air pipe.
[0017] By employing the above technical solution, after the patient completes hot and cold compress treatment, some moisture may remain inside the inflatable airbag. At this time, an air pump can be used to inflate the airbag, and the airflow accelerates the evaporation of water droplets inside the airbag. Simultaneously, the air temperature rises after being heated by the heater, and the hot air further accelerates the evaporation of moisture inside the airbag.
[0018] Preferably, it also includes a locking assembly, wherein the control box is detachably connected to the water storage tank and is locked to the water storage tank by the locking assembly;
[0019] The locking assembly includes a quick-lock, a hanging ring, and a hook. The quick-lock is disposed on the outer wall of the water storage tank, and the hanging ring is connected to the quick-lock. The hook is disposed on the outer wall of the control box, and the hanging ring is hung on the hook and locked by the quick-lock.
[0020] The locking assembly is provided in at least two sets.
[0021] By adopting the above technical solution, the control box and the water storage tank are detachable and can be separated individually. After the water storage tank is filled with hot or cold water, the control box is then installed on the water storage tank, and a locking assembly is used to further secure the control box to the water storage tank, improving the connection stability between the control box and the water storage tank.
[0022] Preferably, it also includes an extension pipe, one end of which is connected to the water inlet pipe and the other end is close to the bottom of the water storage tank.
[0023] By employing the above technical solution, when the cooler water in the inflatable airbag flows back into the water tank, the temperature of the upper layer of water in the tank is neutralized, resulting in a lower temperature for the upper layer compared to the lower layer. The extension tube then delivers the warmer water from the bottom of the water tank to the inlet pipe, which is then used to apply heat to the patient, thereby improving the treatment effect.
[0024] Preferably, a control panel is provided on the outer surface of the control box, and the control panel is used to control the operation of the air wave pressure component and the hot and cold compress circulation component.
[0025] By adopting the above technical solution, personnel can control the operation of the air wave pressure component and the hot and cold compress circulation component through the control panel, thereby realizing pressure therapy or hot and cold compress therapy.
[0026] Preferably, the control box is rotatably connected to the water storage tank, and the extension pipe includes a flexible hose, a first rigid pipe, and a second rigid pipe that are integrally connected in sequence. The flexible hose is connected to one end of the water inlet pipe located in the water storage cavity, so that the angle between the flexible hose and the control box can be changed. The first rigid pipe is used to connect the flexible hose and the second rigid pipe, and the angle between the first rigid pipe and the second rigid pipe is between 120° and 150°.
[0027] It also includes a cylinder, which is mounted on the water storage tank. The piston rod of the cylinder is rotatably connected to one end of the second rigid tube near the bottom of the water storage tank. The angle between the piston rod and the second rigid tube is an obtuse angle. The cylinder is used to control the extension tube to move along the height direction of the water storage tank.
[0028] By adopting the above technical solution, when the piston rod of the cylinder extends, it directly acts on the second rigid tube section, indirectly controlling the extension tube to move away from the bottom of the water storage tank. During the movement of the extension tube, the angle between the piston rod and the second rigid tube section can change due to the rotatable connection between them; simultaneously, the flexible hose section allows the angle between the first rigid tube section and the control box to also change; the control box, subjected to the force of the extension tube, causes relative rotation between the control box and the water storage tank, opening the tank's opening and facilitating the addition of hot or cold water.
[0029] The reason for setting the angle between the first and second rigid pipe sections between 120° and 150° is that, on the one hand, one function of the extension pipe is to lengthen it (to send water near the bottom of the water tank to the inlet pipe). Since the depth of the water tank is fixed, if the angle between the first and second rigid pipe sections is too small, it is easy to cause the overall length of the extension pipe to be too long.
[0030] On the other hand, the extension pipe also serves a supporting function. As the extension pipe moves closer to the opening of the water tank, the piston rod transmits external force to the second rigid pipe section. This force is then transmitted to the first rigid pipe section, and finally, the first rigid pipe section acts on the control box, causing it to rotate. If the angle between the first and second rigid pipe sections is too small, force analysis shows that the first rigid pipe section will not be able to drive the control box to rotate.
[0031] Preferably, it also includes a first sealing ring, which is located outside the water storage cavity and is disposed at the position where the piston rod passes through the water storage tank. A first mounting groove is provided on the bottom wall of the water storage tank, and the first sealing ring is embedded in the first mounting groove.
[0032] The piston rod is respectively provided with a fixing block and a first compression spring. The fixing block is located outside the water storage tank. One end of the first compression spring is connected to the first sealing ring, and the other end is connected to the fixing block.
[0033] By adopting the above technical solution, since the piston rod of the cylinder needs to pass through the water storage tank, adding a first sealing ring can increase the sealing at the position where the piston rod passes through, reducing the possibility of water leaking out of the water storage tank.
[0034] Furthermore, when the piston rod extends, the fixed block moves towards the bottom of the water tank, causing the first compression spring to be compressed. Under the restoring force of the first compression spring, the first compression spring will exert pressure on the first sealing ring, improving the stability of the connection between the first sealing ring and the water tank.
[0035] Preferably, it also includes a second sealing ring, which is located inside the water storage cavity. The second sealing ring is disposed at the position where the piston rod passes through the water storage tank. A second mounting groove is provided on the inner wall of the water storage tank, and the second sealing ring is embedded in the second mounting groove.
[0036] The water storage tank is equipped with a fixed plate and a second compression spring. The piston rod passes through the fixed plate. One end of the second compression spring is connected to the fixed plate, and the other end is connected to the second sealing ring.
[0037] By adopting the above technical solution, the second sealing ring can play a sealing role. When the piston rod extends, there will be relative movement between the piston rod and the second sealing ring. At this time, the second return spring will exert a downward force on the second sealing ring to improve the stability of the connection between the second sealing ring and the water tank.
[0038] Preferably, it also includes fasteners for securing the hose portion to the inlet pipe.
[0039] By adopting the above technical solution, the fastener can further fix the hose part to one end of the water inlet pipe, increasing the bonding force between the hose part and the water inlet pipe.
[0040] Preferably, the outer wall of the water storage tank is provided with a heat insulation layer, which is made of heat insulation material.
[0041] By adopting the above technical solution, the insulation layer can play a role in heat preservation of the water storage tank, reduce the heat transfer between the water in the water storage tank and the outside air, and thus reduce the change in water temperature in the water storage tank.
[0042] Preferably, it also includes a support component, a suction cup, and a linkage component. The support component is disposed at the bottom of the water storage tank, and the cylinder is disposed on the support component. The support component is used to support the water storage tank.
[0043] The suction cup is located at the bottom of the support assembly. The suction cup is connected to the piston rod of the cylinder through the linkage assembly. When the piston rod of the cylinder moves upward in the vertical direction, the control box rotates in the direction away from the opening of the water storage tank. The linkage assembly is used to control the suction cup to adhere to the ground.
[0044] By adopting the above technical solution, the support component is fixedly installed at the bottom of the water tank, providing overall support for the water tank and allowing the treatment device to be placed stably on the ground or tabletop. Simultaneously, the support component also serves as a carrier for the cylinder, facilitating its installation. When the treatment device is in use, the control box is closed at the opening of the water tank, at which point the lower side of the suction cup is in contact with the ground, forming a sealed space between the suction cup and the ground.
[0045] When the therapeutic device is not in use, the piston rod of the cylinder moves vertically upward, causing the control box and water tank to rotate relative to each other. This tilting of the control box alters the center of gravity of the therapeutic device, affecting its stability. Simultaneously, as the piston rod extends, the linkage mechanism creates negative pressure on the suction cup, allowing it to adhere to the ground under the device's own weight, thus increasing its stability.
[0046] In summary, this application includes at least one of the following beneficial technical effects:
[0047] (1) By setting up a hot and cold compress circulation component and a water tank, when it is necessary to perform hot and cold compress treatment on the patient, according to the user's needs, first add cold water or hot water to the water tank (add cold water for cold compress, and add hot water for hot compress); then use the control box to run the water pump, at which time the water in the water tank is input into the external airbag along the water inlet pipe, thereby realizing cold compress or hot compress.
[0048] (2) By setting up a heater, the air temperature rises after being heated by the heater, and the air pump inflates the airbag. Under the action of the hot airflow, the evaporation of water droplets inside the airbag is accelerated.
[0049] (3) By setting up an extension pipe, the extension pipe delivers water at a higher temperature at the bottom of the water tank to the inlet pipe, and then applies hot compresses to the patient to improve the treatment effect. Attached Figure Description

Without conflict, those skilled in the art can combine and integrate the different embodiments or examples shown in this application, as well as the features of those embodiments or examples.
[0064] Example 1
[0065] This application discloses an air wave hot and cold compress rapid switching therapy device. (See also...) Figure 1 and Figure 2 The therapeutic device includes a control box 1, an air wave pressure component 2, a hot and cold compress circulation component 3, and a water tank 4. The air wave pressure component 2 and the hot and cold compress circulation component 3 are both installed on the control box 1. The air wave pressure component 2 is used to apply pressure therapy to the patient's limbs, and the hot and cold compress circulation component 3 is used to apply cold or hot compress therapy to the patient's limbs.
[0066] The water storage tank 4 has an opening and forms a water storage cavity 5, which is used to store cold or hot water. The control box 1 is located on the side of the water storage tank 4 near the opening and is connected to the water storage tank 4.
[0067] In this embodiment, the connection between the control box 1 and the water storage tank 4 is a detachable connection. Specifically, in conjunction with... Figure 3 The control box 1 and the water tank 4 are interlocked and locked together by a locking assembly 6. The locking assembly 6 includes a quick-lock buckle 61, a hanging ring 62, and a hook 63. The quick-lock buckle 61 is fixedly connected to the outer wall of the water tank 4, and the hanging ring 62 is connected to the quick-lock buckle 61. The hook 63 is fixedly connected to the outer wall of the control box 1, and the hanging ring 62 is hung on the hook 63 and locked by the quick-lock buckle 61, thereby locking the control box 1 to the water tank 4. At least two sets of locking assemblies 6 are provided. As shown in the figure, in this embodiment, there are two sets of locking assemblies 6, symmetrically distributed, which together lock the control box 1 to the water tank 4.
[0068] The air wave pressure assembly 2 includes an air pump 21 and an air tube 22. The air pump 21 is installed inside the control box 1 and connected to the air tube 22, which is connected to an external inflatable airbag. When pressure therapy is required for a patient, the air pump 21 is activated to provide power for air, which is then transported along the air tube 22 to the inflatable airbag, thereby inflating and deflating the airbag and completing the air wave pressure therapy for the patient.
[0069] The hot and cold compress circulation assembly 3 includes an inlet pipe 31, a water pump 32, and a return pipe 33. One end of the inlet pipe 31 is installed inside the water storage tank 4, and the other end is used to connect to an external inflatable airbag. The water pump 32 is installed on the inlet pipe 31 and is located inside the control box 1. One end of the return pipe 33 is also installed inside the water storage tank 4, and the other end is used to connect to an external inflatable airbag.
[0070] When patients need to receive hot or cold compress treatment, according to the user's needs, first add cold or hot water to the water tank 4 (cold water for cold compress, hot water for hot compress); then use the control box 1 to run the water pump 32, at which time the water in the water tank 4 is input into the external inflatable air bag along the water inlet pipe 31, thereby realizing cold or hot compress, improving the patient's medical experience and treatment effect.
[0071] During hot and cold compress therapy (taking hot compress as an example), the hot water inside the inflatable bladder transfers heat to the body. The water temperature inside the bladder gradually decreases, and this temperature change affects the treatment effect. At this point, the valve on the return water pipe 33 can be opened, and the inflatable bladder can be pressed or squeezed to allow the cooler water to flow back into the water tank 4. Then, the water pump 32 is controlled to deliver the warmer hot water from the water tank 4 to the inflatable bladder to continue the hot compress treatment.
[0072] In addition, a heater 7 is installed on the air pump 21 to heat the fluid in the air tube 22. After the patient has undergone hot and cold compress treatment, some moisture may remain inside the inflatable airbag. At this time, air can be pumped into the inflatable airbag by the air pump 21. Under the action of airflow, the evaporation of water droplets inside the inflatable airbag is accelerated. At the same time, the air temperature rises after being heated by the heater 7, and the hot air can accelerate the evaporation of moisture inside the inflatable airbag.
[0073] The control box 1 has a control panel 8 fixedly mounted on its outer surface. The control panel 8 is used to control the operation of the air wave pressure component 2 and the hot and cold compress circulation component 3. Operators can quickly control the working status of the air pump 21, water pump 32, or heater 7 through the control panel 8. At the same time, a handle 16 is rotatably connected to the control box 1. When the treatment device needs to be moved, the operator can grasp the handle 16 and lift the control box 1 and the water tank 4 at the same time for easy transport.
[0074] Optionally, according to some embodiments of this application, please refer to Figure 2 An extension pipe 9 is also installed inside the water storage tank 4. One end of the extension pipe 9 is connected to the end of the water inlet pipe 31 located inside the water storage tank 4, and the other end of the extension pipe 9 is set vertically and close to the bottom of the water storage tank 4.
[0075] When the cooler water in the inflatable airbag flows back into the water tank 4, the temperature of the water in the upper layer of the water tank 4 is neutralized, making it lower than the temperature of the water in the lower layer. The extension tube 9 delivers the warmer water from the bottom of the water tank 4 to the inlet pipe 31, and then the patient is given a hot compress to improve the treatment effect.
[0076] According to some embodiments of this application, optionally, the outer wall of the water storage tank 4 is also covered with an insulation layer (not shown in the figure). The insulation layer is made of heat-insulating material, which may be, but is not limited to, polyurethane foam, glass wool, and rock wool. The insulation layer has poor thermal conductivity, which can slow down the heat transfer rate, thereby reducing heat loss and achieving the function of heat insulation for the water storage tank 4. This reduces the heat transfer between the water in the water storage tank 4 and the outside air, and thus reduces the change in water temperature in the water storage tank 4.
[0077] Example 2
[0078] Based on the above embodiments, such as Figure 4 As shown, the difference between Embodiment 2 and Embodiment 1 lies in the connection method between the control box 1 and the water storage tank 4. The control box 1 is rotatably connected to the opening side of the water storage tank 4. Specifically, the extension pipe 9 includes a flexible hose 91, a first rigid pipe 92, and a second rigid pipe 93 connected sequentially and integrally. The flexible hose 91 is a flexible metal or plastic pipe, and the first rigid pipe 92 connects the flexible hose 91 and the second rigid pipe 93. The first rigid pipe 92 and the second rigid pipe 93 are rigid metal or plastic pipes. One end of the flexible hose 91 is sleeved on the end of the inlet pipe 31 located inside the water storage tank 4, and the connection between the flexible hose 91 and the water storage tank 4 is achieved under the action of friction. At the same time, because the flexible hose 91 is flexible, the angle between the flexible hose 91 and the control box 1 can change when the flexible hose 91 is subjected to external force. The angle between the first rigid pipe 92 and the second rigid pipe is an obtuse angle, specifically between 120° and 150°. The clamp formed by the first rigid tube section 92 and the second rigid tube section 93 is oriented toward the rotation axis of the control box 1.
[0079] A cylinder 10 is also fixedly installed at the bottom of the water storage tank 4. The piston rod of the cylinder 10 passes through the bottom of the water storage tank 4 and is rotatably connected to the end of the second rigid tube 93 away from the flexible tube 91. The piston rod extends and retracts along the height direction of the water storage tank 4. The cylinder 10 is used to control the movement of the extension tube 9 along the height direction of the water storage tank 4. When the control box 1 is placed over the opening of the water storage tank 4, the angle between the piston rod of the cylinder 10 and the second rigid tube 93 is an obtuse angle.
[0080] When the piston rod of cylinder 10 extends, it acts directly on the second rigid tube 93, indirectly controlling the extension tube 9 to move away from the bottom of the water storage tank 4. During the movement of the extension tube 9, the angle between the piston rod and the second rigid tube 93 can change due to the rotatable connection between them; at the same time, the flexible hose 91 allows the angle between the first rigid tube 92 and the control box 1 to also change; the control box 1 is subjected to the force of the extension tube 9, causing it to rotate relative to the water storage tank 4, opening the opening of the water storage tank 4, thus facilitating the addition of hot or cold water to the tank.
[0081] The angle between the first rigid pipe section 92 and the second rigid pipe section 93 is set between 120° and 150° for two reasons. First, one function of the extension pipe 9 is to lengthen the pipe (to deliver water near the bottom of the water storage tank 4 to the inlet pipe 31). Since the depth of the water storage tank 4 is fixed, if the angle between the first rigid pipe section 92 and the second rigid pipe section 93 is too small, the overall length of the extension pipe 9 will be too long, resulting in more material consumption. If the angle between the first rigid pipe section 92 and the second rigid pipe section 93 is too large, in the initial state (with the control box 1 covering the water storage tank 4), the angle between the piston rod and the second rigid pipe section 93 will be close to a flat angle, making it difficult for the piston rod and the second rigid pipe section 93 to rotate.
[0082] On the other hand, another function of the extension pipe 9 is support. As the extension pipe 9 moves closer to the opening of the water tank 4, the piston rod transmits external force to the second rigid pipe section 93. This force is then transmitted to the first rigid pipe section 92, and finally, the first rigid pipe section 92 acts on the control box 1, causing it to rotate. If the angle between the first rigid pipe section 92 and the second rigid pipe section 93 is too small, force analysis shows that the component force of the first rigid pipe section 92 acting on the control box 1 is small, making it difficult for the first rigid pipe section 92 to drive the control box 1 to rotate. If the angle between the first rigid pipe section 92 and the second rigid pipe section 93 is too large, in the initial state (with the control box 1 covering the water tank 4), the angle between the first rigid pipe section 92 and the control box 1 is close to a right angle, making it difficult for the flexible hose section 91 and the control box 1 to rotate.
[0083] Optionally, according to some embodiments of this application, please refer to Figure 4 and Figure 5 A first sealing ring 11 is also installed on the water storage tank 4. The first sealing ring 11 is located at the position where the piston rod passes through the water storage tank 4. Specifically, a first mounting groove 12 is provided on the bottom wall of the water storage tank 4, and the first sealing ring 11 is embedded in the first mounting groove 12. Since the piston rod of the cylinder 10 needs to pass through the water storage tank 4, the addition of the first sealing ring 11 can increase the sealing at the position where the piston rod passes through, and reduce the possibility of water leakage from inside the water storage tank 4.
[0084] During the extension and retraction of the piston rod, the piston rod will move relative to the first sealing ring 11 (the first sealing ring 11 remains stationary). At this time, there will be friction between the first sealing ring 11 and the piston rod. This force can easily cause the first sealing ring 11 to detach from the first mounting groove 12. Therefore, a fixing block 13 and a first compression spring 14 are respectively installed on the piston rod. The fixing block 13 is located outside the water storage tank 4 and is fixedly connected to the piston rod; the first compression spring 14 is sleeved on the piston rod, one end of the first compression spring 14 is connected to the first sealing ring 11, and the other end is fixedly connected to the fixing block 13.
[0085] When the piston rod extends, the fixing block 13 moves towards the bottom of the water tank 4, compressing the first compression spring 14. Under the restoring force of the first compression spring 14, it exerts pressure on the first sealing ring 11, improving the stability of the connection between the first sealing ring 11 and the water tank 4 and reducing the possibility of the first sealing ring 11 falling off. As the piston rod gradually retracts to its initial state, the first compression spring 14 maintains an elastic pressure on the first sealing ring 11. This elastic pressure is always opposite to the direction of piston rod retraction, keeping the first sealing ring 11 pressed against the water tank 4. This pressure gradually decreases and eventually becomes zero.
[0086] Combination Figure 6 In addition, a second mounting groove 18 is provided on the inner wall of the water storage tank 4, and a second sealing ring 17 is embedded in the second mounting groove 18. The second sealing ring 17 is also installed at the position where the piston rod passes through the water storage tank 4 and is located above the first sealing ring 11. A fixing plate 19 and a second compression spring 20 are also installed in the water storage tank 4. The fixing plate 19 is fixedly connected to the water storage cavity 5, and the piston rod passes through the fixing plate 19; one end of the second compression spring 20 is connected to the fixing plate 19, and the other end is connected to the second sealing ring 17.
[0087] The second sealing ring 17 can seal the water storage tank 4. When the piston rod extends, there will be relative movement between the piston rod and the second sealing ring 17, and the second sealing ring 17 tends to move with the piston rod. At this time, the second return spring will exert a downward force on the second sealing ring 17 to improve the stability of the second sealing ring 17 in the water storage tank 4.
[0088] Optionally, according to some embodiments of this application, please refer to Figure 5The water storage tank 4 is also equipped with fasteners 15, which are used to fix the hose part 91 to the water inlet pipe 31. The fasteners 15 are clamps. After the hose part 91 is fitted onto the water inlet pipe 31, the clamps are used to further fix the hose part 91 to the water inlet pipe 31, increasing the pressure between the hose part 91 and the water inlet pipe 31 and reducing the possibility of the extension pipe 9 falling off the water inlet pipe 31.
[0089] Optionally, according to some embodiments of this application, please refer to Figure 7 The bottom of the water tank 4 is also equipped with a support component 23, a suction cup 24, and a linkage component 25. The support component 23 is fixedly installed at the bottom of the water tank 4 and is used to support the water tank 4. Specifically, the support component 23 includes a support rod 231 and a support block 232. The support rod 231 is arranged vertically and one end is fixedly connected to the bottom of the water tank 4, and the other end is fixedly connected to the support block 232. The cylinder 10 is installed on the support block 232, which provides support so that the treatment device can be placed stably on the ground.
[0090] A suction cup 24 is mounted on the lower surface of the support block 232 and is connected to the piston rod of the cylinder 10 via a linkage assembly 25. The linkage assembly 25 includes a connecting rod 251, a sliding column 252, and a pressure plate 253. The sliding column 252 is disposed within the support rod 231 and slides vertically within it. A slotted hole 26 is provided on the side wall of the support rod 231, oriented along the moving direction of the sliding column 252. One end of the connecting rod 251 is connected to the piston rod of the cylinder 10, and the other end passes through the slotted hole 26 and connects to the sliding column 252. The pressure plate 253 is fixedly connected to the end of the sliding column 252 near the suction cup 24 and is located within the suction cup 24. The pressure plate 253 has a circular cross-section, and the suction cup 24 is frustum-shaped. The diameter of the pressure plate 253 is equal to the mid-section diameter of the suction cup 24.
[0091] When the therapeutic device is in use, the control box 1 is closed at the opening of the water tank 4. At this time, the lower side of the suction cup 24 is in contact with the ground, and the suction cup 24 and the ground form a sealed space; the surface of the pressure plate 253 is also in contact with the ground, playing a supporting role.
[0092] When the therapeutic device is not in use, the piston rod of cylinder 10 moves vertically upward, causing the control box 1 and water tank 4 to rotate relative to each other. Because the control box 1 tilts, the center of gravity of the therapeutic device changes, affecting its stability. Simultaneously, as the piston rod of cylinder 10 extends, it drives the connecting rod 251 to move vertically upward. The connecting rod 251 then moves the sliding column 252 within the support rod 231, causing the pressure block to move away from the ground. At this point, the suction cup 24 generates negative pressure under the weight of the therapeutic device itself, further adhering to the ground and increasing the stability of the therapeutic device.
[0093] The implementation principle of the air wave hot and cold compress rapid switching therapy device in this application embodiment is as follows: when pressure therapy is required for the patient, the air wave pressure component 2 can be connected to the external inflatable airbag, and the air wave pressure component 2 can inflate and deflate the inflatable airbag to achieve pressure therapy for the patient.
[0094] When patients need to receive hot or cold compress treatment, according to the user's needs, first add cold or hot water to the water tank 4 (cold water for cold compress, hot water for hot compress); then use the control box 1 to run the water pump 32, at which time the water in the water tank 4 is input into the external inflatable air bag along the water inlet pipe 31, thereby realizing cold or hot compress, improving the patient's medical experience and treatment effect.
[0095] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
