Description

Technical Field

[0001] This application relates to the field of air wave therapy devices, and more particularly to an air wave therapy device with adaptive temperature adjustment. Background Technology

[0002] Air wave therapy devices are rehabilitation medical devices that use the principle of periodic inflation to compress and massage a large area of ​​the limbs, increasing venous blood flow in patients at risk of venous thrombosis, thereby significantly increasing blood flow speed, reducing blood stasis, and achieving the goal of preventing deep vein thrombosis and pulmonary embolism.

[0003] Existing air wave therapy devices can adjust the temperature according to actual needs, mainly by switching between cold and hot water tanks to regulate the water source temperature. This method is relatively expensive. Utility Model Content

[0004] In order to enable air wave therapy devices to adjust temperature while keeping costs down, this application provides an air wave therapy device with adjustable temperature.

[0005] The air wave therapy device with adjustable temperature provided in this application adopts the following technical solution: An adaptive temperature-adjustable air wave therapy device includes a cold water tank, a first three-way valve, a water pump, a temperature sensor, a water bag, a second three-way valve, and a one-way valve connected in sequence. The outlet of the one-way valve is connected to the inlet of the cold water tank; the other inlet of the first three-way valve is connected to the outside; the other outlet of the second three-way valve is connected to the water pump; and the water bag is a massage component.

[0006] By adopting the above technical solution, a temperature sensor is used to detect the temperature of the liquid flowing from the water pump to the water bag, and the control system of the air wave therapy device compares the detected temperature with the preset temperature.

[0007] If the detected temperature is lower than the preset temperature, the passage between the second three-way valve and the check valve is closed, and the passage between the second three-way valve and the water pump is opened, so that the circulation path of the liquid is water pump—temperature sensor—water bag—second three-way valve—water pump, thereby using the body temperature of the human body to raise the temperature of the liquid circulating in the path to the same as the human body temperature. If the detected temperature is higher than the preset temperature, the passage between the second three-way valve and the water pump is closed, while the passage between the second three-way valve and the check valve is opened. This results in the following liquid circulation path: water pump—temperature sensor—water bladder—second three-way valve—cold water tank—first three-way valve—water pump. The cooler liquid in the cold water tank then cools the liquid in the circulation path to body temperature. This allows for adaptive temperature regulation of the water bladder, ensuring patient comfort. Furthermore, the system allows for temperature regulation by mixing cold water with ambient water, avoiding the need for a hot water tank and resulting in relatively lower costs.

[0008] In addition, when draining the water bladder, the passage between the cold water tank and the first three-way valve is cut off, so that the first three-way valve is connected to the outside. The water pump is used to introduce outside air into the water bladder, and then the air is used to squeeze the liquid in the water bladder into the cold water tank, thereby realizing the drainage of the water bladder.

[0009] Optionally, it also includes a one-way valve, the outlet of which is connected to the inlet of the cold water tank.

[0010] Optionally, a first insulation component is provided on the outside of the cold water tank.

[0011] By adopting the above technical solution, the first insulation component is used to keep the liquid in the cold water tank insulated, reducing the heat exchange between the liquid in the cold water tank and the outside world, thereby reducing the energy consumption of the air wave therapy device.

[0012] Optionally, the first insulation component is detachably connected to the cold water tank.

[0013] By adopting the above technical solution, on the one hand, it facilitates the transportation and storage of the air wave therapy device; on the other hand, it also facilitates the reuse of the first insulation component.

[0014] Optionally, the inlet and outlet of the cold water tank are both located on the same side wall of the cold water tank; the first insulation component includes a frame with an opening for the cold water tank to pass through.

[0015] By adopting the above technical solution, when connecting the first insulation component to the cold water tank, it is only necessary to insert the cold water tank into the first insulation component through the opening, which is convenient.

[0016] Optionally, the first insulation component further includes a first airbag, which is disposed within the frame and is used to abut against the outer wall of the cold water tank.

[0017] By adopting the above technical solution, on the one hand, the air in the first airbag is used for heat insulation; on the other hand, the volume of the first airbag can be adjusted by inflating and deflating, so that the first insulation component can be used for cold water tanks of different sizes, thereby improving the flexibility of the first insulation component.

[0018] Optionally, the first airbag is detachably connected to the frame.

[0019] By adopting the above technical solution, on the one hand, it is convenient to clean and maintain the first airbag; on the other hand, it is also convenient to store and transport the first insulation component.

[0020] Optionally, the cold water tank, the first three-way valve, the water pump, the temperature sensor, the water bladder, the second three-way valve, and the one-way valve are all connected by pipes, and the outer wall of the pipes is provided with a second heat insulation component.

[0021] By adopting the above technical solution, the flow in the pipeline is controlled by the second insulation component.

[0022] Optionally, the second insulation component includes a flexible outer shell and a second airbag connected to the inside of the outer shell; the outer shell is sheet-shaped, and a first zipper and a second zipper are respectively provided on both sides of the outer shell, with the second zipper cooperating with the first zipper.

[0023] By adopting the above technical solution, the first zipper strip and the second zipper strip interact with each other.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a first three-way valve and a second three-way valve, the three-way function can be used to adjust the liquid temperature in the circulation path by setting up only one cold water tank. The adjustment is based on human body temperature, which reduces costs while ensuring patient comfort. 2. By detachably connecting the first insulation component to the outside of the cold water tank, the liquid in the cold water tank is insulated and heat-insulated, reducing the temperature exchange between the liquid in the cold water tank and the outside environment, and reducing the energy consumption of the entire air wave therapy device. 3. By installing a second insulation component outside the pipes in the circulation path, the liquid in the circulation path is insulated and heat-insulated, reducing the temperature exchange between the liquid in the circulation path and the outside environment, and reducing the energy consumption of the entire air wave therapy device.

Detailed Implementation

[0031] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0032] This application discloses an air wave therapy device with adjustable temperature.

[0033] Example 1 Reference Figure 1 The adaptive temperature-adjustable air wave therapy device includes a cold water tank 1, a first three-way valve 2, a water pump 3, a temperature sensor 4, a water bag 5, a second three-way valve 6, and a one-way valve 7 connected in sequence. The outlet of the one-way valve 7 is connected to the inlet of the cold water tank 1; the other inlet of the first three-way valve 2 is connected to the outside; the other outlet of the second three-way valve 6 is connected to the water pump 3; and the water bag 5 is a massage component.

[0034] With this design, temperature sensor 4 is used to detect the temperature of the liquid flowing from water pump 3 to water bag 5, and the control system of air wave therapy device compares the detected temperature with the preset temperature.

[0035] Reference Figure 1 If the detected temperature is lower than the preset temperature, the passage between the second three-way valve 6 and the one-way valve 7 is closed, and the passage between the second three-way valve 6 and the water pump 3 is opened, so that the circulation path of the liquid is water pump 3—temperature sensor 4—water bag 5—second three-way valve 6—water pump 3, thereby using the body temperature of the human body to raise the temperature of the liquid circulating in the path to the same as the human body temperature. Reference Figure 2 If the detected temperature is higher than the preset temperature, the passage between the second three-way valve 6 and the water pump 3 is closed, and the passage between the second three-way valve 6 and the one-way valve 7 is opened. This results in the following liquid circulation path: water pump 3—temperature sensor 4—water bladder 5—second three-way valve 6—one-way valve 7—cold water tank 1—first three-way valve 2—water pump 3. This utilizes the lower-temperature liquid in the cold water tank 1 to cool the liquid in the circulation path to the same temperature as the human body. This allows for adaptive temperature regulation of the water bladder 5, ensuring patient comfort, and allows for temperature regulation by mixing cold water with external water, avoiding the need for a hot water tank and resulting in relatively low cost.

[0036] Reference Figure 3 When draining the water bladder 5, the passage between the cold water tank 1 and the first three-way valve 2 is cut off, so that the first three-way valve 2 is connected to the outside. The water pump 3 is used to introduce outside air into the water bladder 5, and then the air is used to squeeze the liquid in the water bladder 5 into the cold water tank 1, thereby realizing the drainage of the water bladder 5.

[0037] Specifically, the cold water tank 1, the first three-way valve 2, the water pump 3, the temperature sensor 4, the water bladder 5, the second three-way valve 6, and the one-way valve 7 are all connected by pipes.

[0038] The inlet and outlet of the cold water tank 1 are both located on the same side wall of the cold water tank 1 to facilitate connection with other components, as well as to facilitate installation and maintenance.

[0039] The first three-way valve 2 can be either an electric three-way valve or a manual three-way valve. The electric three-way valve can achieve automatic control, automatically adjusting the water flow direction based on the signal from the temperature sensor 4; the manual three-way valve is simple to operate and has a lower cost.

[0040] Temperature sensor 4 is used to monitor the temperature of the water flow in real time. It can be a thermocouple temperature sensor 4, a thermistor temperature sensor 4, etc. Thermocouple temperature sensor 4 has the advantages of wide measurement range and high accuracy; thermistor temperature sensor 4 has fast response speed and high sensitivity.

[0041] The check valve 7 is used to ensure unidirectional water flow and prevent backflow. The check valve 7 can be a ball check valve 7, a butterfly check valve 7, etc. The ball check valve 7 has a simple structure and good sealing performance; the butterfly check valve 7 has strong flow capacity and low pressure loss.

[0042] Example 2 Reference Figure 4 and Figure 5 The difference between this embodiment and embodiment 1 is that a first insulation component 8 is provided outside the cold water tank 1, and the first insulation component 8 is detachably connected to the cold water tank 1.

[0043] In this embodiment, the inlet and outlet of the cold water tank 1 are both located on one side. The first insulation component 8 includes a frame 81 and a first airbag 82. The frame 81 has an opening for the cold water tank 1 to pass through. The first airbag 82 is disposed inside the frame 81 and is used to abut against the outer wall of the cold water tank 1. Thus, the first insulation component 8 and the cold water tank 1 are detachably connected by means of a sleeve.

[0044] Furthermore, the first airbag 82 is detachably connected to the frame 81. In this embodiment, the first airbag 82 is detachably connected to the edge of the frame 81 at its edge via a zipper.

[0045] The cold water tank 1, the first three-way valve 2, the water pump 3, the temperature sensor 4, the water bladder 5, the second three-way valve 6, and the one-way valve 7 are all connected by pipes. The outer walls of all the pipes are equipped with a second insulation component 9, which includes a flexible outer shell 91 and a second air bladder 92 connected to the inside of the outer shell 91. The outer shell 91 is sheet-like, and a first zipper strip 93 and a second zipper strip 94 are respectively provided on both sides of the outer shell 91, with the second zipper strip 94 cooperating with the first zipper strip 93.

[0046] The implementation principle of Example 2 is as follows: by setting a first insulation component 8 and a second insulation component 9, the first insulation component 8 is used to insulate the cold water tank 1, and the second insulation component 9 is used to insulate the pipe through which the liquid flows, thereby reducing the energy exchange between the liquid and the outside world in the entire circulation path and further reducing energy consumption.

[0047] 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.
