Description

[Technical Field]

[0001] FIELD OF THE INVENTION The present invention relates to the field of medical devices, and more particularly to a portable cold therapy system and device that provides selectable heat and compression therapy. [Background technology]

[0002] Cold therapy systems and devices are used in a wide range of applications, including athletic rehabilitation, pain relief, swelling reduction, and wound healing. Cold therapy systems and devices in the existing technology mainly utilize semiconductor cooling, but the cold therapy systems and devices that utilize semiconductor cooling have the following drawbacks: 1. When cooling semiconductors, the temperature controllability of the cold therapy device is limited. If the control is inadequate, the heat loss of the chip may be excessive, resulting in a loss of cooling effect. 2. The cooling effect of semiconductor cooling is easily affected by the ambient temperature. When the ambient temperature exceeds a certain range, the cooling effect will decrease. 3. Semiconductor cooling typically involves fixing the cooling chip to a heat sink and controlling the chip's operation with an electric current to generate heat. When an electric current passes through the chip, the N-type semiconductor absorbs the surrounding heat and the P-type semiconductor releases heat, resulting in one side of the chip being in a low temperature state and the other side being in a high temperature state. The method of using electrical energy to drive the cooling by connecting a water pipe and flowing water over the low-temperature side of the chip requires high power consumption, large equipment size, and a power supply, making it difficult to use in environments without or far from a power source, and inconvenient to carry. Furthermore, existing cold therapy systems and devices only have the cooling function of cooling and applying a cold pad with protective equipment, and lack functional versatility, making it difficult to adapt to a variety of situations. Therefore, the development of adaptive cooling systems and cooling treatment devices has become an urgent technical challenge for those skilled in the art.

[0041] It should be noted that there may be one or more compressors 11, condensers 13, fans 14, and heat exchangers 15. A plurality of compressors 11 are arranged in series, a plurality of condensers 13 are arranged in series, the working surface of each of the fans 14 faces the corresponding condenser 13, and a plurality of heat exchangers 15 are arranged in series. The liquid may be water, alcohol, antifreeze, or the like, and preferably, alcohol with a concentration of 10% is used.

[0042] As shown in Figures 2 and 6, the first liquid inlet 121 may be provided at the top of the liquid storage tank 12, or as shown in Figures 3 and 12, the first liquid inlet 121 may be provided at the side edge of the liquid storage tank 12. In addition, a refrigerant addition port is provided at the branching point of the first pipe 171, so that the cooling temperature can be maintained when the cooling mechanism is in operation for a long period of time. When the cooling mechanism is used in a circulating manner for a long period of time, the heat exchange under ideal conditions cannot be fully achieved, and the expected cooling effect cannot be obtained. Therefore, a refrigerant can be added periodically to improve the cooling effect.

[0043] The first cooling plate 151 is a welded plate type heat exchanger, and the liquid in the first protective equipment A flows into the second liquid inlet 1513 through the first liquid inlet 121, and after the liquid is cooled in the welded plate type heat exchanger, it flows into the liquid storage tank 12 through the second liquid outlet 1514.

[0044] The first pipe 171 and the second pipe 172 fluidly penetrate each other, and the second pipe 172 and the third pipe 173 fluidly penetrate each other. In fact, the first pipe 171, the second pipe 172, and the third pipe 173 are all on the same pipe, which connects the compressor 11, the heat exchanger 15, and the condenser 13 to form a closed circulation loop. For example, the first pipe 171 includes a compressor section, a first pipe connection section protruding from the compressor 11 and connected to the heat exchanger 15, and a heat exchanger section, the second pipe 172 includes a second pipe connection section protruding from the heat exchanger 15 and connected to the condenser 13, and a condenser section, and the third pipe 173 includes a third pipe connection section protruding from the condenser 13 and connected to the compressor 11.

[0045] The refrigerant enters the first cooling plate 151 through the second pipe 172 and the first intake port 1512, and then returns to the compressor 11 through the first exhaust port 1511 and the first pipe 171, thereby cooling the first cooling plate 151 and exchanging heat with the liquid in the first cooling plate 151, thereby lowering the temperature of the liquid.

[0046] The problem that this embodiment aims to solve is the technical problem that the cooling effect of the cooling mechanism of the protective equipment is insufficient and the efficiency is low.

[0047] The portable cold therapy system with selectable heating and compression therapy provided by the present invention has the following beneficial effects: the cooling mechanism is provided with a compressor 11, a condenser 13, a fan 14, and a heat exchanger 15; a high-temperature, high-pressure gas refrigerant is transported from the compressor 11 to the condenser 13 via the third pipe 173, and the refrigerant is liquefied after heat dissipation; at this time, the temperature of the high-temperature, high-pressure gas refrigerant is high, so the fan 14 is used to dissipate heat from the gas refrigerant in the condenser 13, and the gas refrigerant is liquefied by dissipating heat; the liquid refrigerant is transported from the condenser 13 to the heat exchanger 15 via the second pipe 172, and the liquid refrigerant is converted into liquid in the storage tank 12 by the heat exchanger 15. The gas refrigerant exchanges heat with the heat exchanger 15, absorbs heat from the liquid, vaporizes, and drops in temperature. The gas refrigerant is transported from the heat exchanger 15 to the compressor 11 via the first pipe 171, and is compressed by the compressor 11. The liquid in the liquid storage tank 12 is circulated and cooled. The cooled liquid in the liquid storage tank 12 flows into the first protective device A via the first liquid outlet 122. The liquid in the first protective device A flows into the liquid storage tank 12 via the first liquid inlet 121. The liquid is circulated and repeatedly cooled. The first protective device A is used to cool the body, achieving a therapeutic effect. As shown in Figure 28, the cooling rate is: 2 When the first protective device A is used, the surface temperature of the first protective device A reaches 5°C within 10 minutes, and the cooling power is 75 watts, achieving a cooling capacity of 250 watts, with good cooling effect, high efficiency, stability, and low power consumption. Furthermore, the device has a compact structure, light weight, and is easy to carry.

[0048] Furthermore, since the cooling / heating mechanism of the present application is provided inside or on the outer bottom of the liquid storage tank 12, it comes into direct or indirect contact with the liquid in the liquid storage tank 12, allowing the liquid to be pre-cooled or pre-heated, so that it can be used immediately when the user requires treatment. In one embodiment, a liquid level detector 61 and a temperature sensor 62 are further provided in the reservoir tank 12, and both the liquid level detector 61 and the temperature sensor 62 are electrically connected to the control assembly.

[0049] In addition, a liquid level detector 61 is provided in the storage tank 12 and is used to detect the height or low of the liquid level, and a temperature sensor 62 is provided on the side edge of the storage tank 12 and is used to detect the temperature of the liquid in the storage tank 12, and the temperature is controlled by the control assembly to achieve an appropriate cold or hot padding effect.

[0050] In one embodiment, the second pipe 172 includes a flow-control device, which is arranged between the heat exchanger 15 and the condenser 13, and the condenser 13 includes a heat conduction tube, one end of which protrudes from the condenser 13 and is connected to the flow-control device, and the other end of the heat conduction tube protrudes from the condenser 13 and is connected to the compressor 11.

[0051] In addition, the second pipe 172 includes a second pipe connection section protruding from the heat exchanger 15 and connected to the condenser 13, a condenser section, and a flow-reducing device is provided on the second pipe connection section protruding from the heat exchanger 15 and connected to the condenser 13, and the flow-reducing device may be a capillary tube, and after the second pipe connection section protrudes from the heat exchanger 15, the diameter of the pipe tends to shrink to form a capillary tube, preferably the diameter shrinks to 3 to 6 times the original pipe diameter, and the flow-reducing device may be a flow-reducing valve or other flow-reducing pressure-reducing device.

[0052] When the liquid refrigerant after heat dissipation passes through the capillary tube with a small diameter, the flow rate becomes slower due to the small cross-sectional area of ​​the pipe, and the pressure drops, which in turn causes the temperature to drop. At this time, the liquid refrigerant, which has a high pressure immediately after being output from the condenser 13, passes through the capillary tube and is decompressed.

[0053] The heat transfer tube is a copper tube, which is U-shaped and curved along the inner wall of the condenser 13. High-temperature and high-pressure gas refrigerant enters the condenser section, and the copper tube is installed in the pipe of the condenser section to absorb the heat of the gas refrigerant and dissipate it into the surrounding environment. At the same time, the working surface of the fan 14 faces the position of the copper tube in the condenser 13, further promoting the heat dissipation and liquefaction of the refrigerant. After heat dissipation by the copper tube and the fan 14, the liquid refrigerant enters the capillary tube and is decompressed, and the liquid refrigerant is transported to the heat exchanger 15 via the second pipe 172.

[0054] In one embodiment, the device further includes a water pump 21, wherein the first liquid outlet 122 is connected to a third liquid inlet A1 of the first protector A via the water pump 21, and the water pump 21 is electrically connected to the control assembly; When the water pump 21 operates, the liquid in the liquid storage tank 12 flows into the first protective device A through the first liquid outlet 122 and the third liquid inlet A1, and the liquid in the first protective device A flows back into the liquid storage tank 12 through the third liquid outlet A2 of the first protective device A and the first liquid inlet 121.

[0055] 7, the first liquid inlet 121 is connected to the first connector, the first liquid outlet 122 is connected to the second connector 123, and the first connector and the second connector 123 are each used to connect to a liquid pipe. The liquid in the liquid storage tank 12 flows out from the first liquid outlet 122, is pressurized by the water pump 21, and then flows into the first protector A.

[0056] In one embodiment, as shown in FIG. 10 , the compressor 11 is further provided with a four-way valve 18, the compressor 11 is connected to the four-way valve 18 via the first pipe 171 and then connected to the heat exchanger 15, the condenser 13 is connected to the four-way valve 18 via the third pipe 173 and then connected to the compressor 11, the four-way valve 18 is electrically connected to the control assembly, and the control assembly controls the four-way valve 18 to change the flow direction, so that the gas refrigerant in the compressor 11 passes through the heat exchanger 15 and then passes through the condenser 13 to produce a heating effect.

[0057] The control assembly controls the passages inside the four-way valve 18, causing the high-temperature, high-pressure gaseous refrigerant in the compressor 11 to first pass through the heat exchanger 15. The high-temperature, high-pressure gaseous refrigerant releases heat in the heat exchanger 15 and liquefies, raising the temperature of the liquid in the storage tank 12. After the liquid refrigerant is decompressed through a capillary tube, it absorbs heat and vaporizes in the condenser 13, and the gaseous refrigerant returns to the compressor 11. The installation of the four-way valve 18 allows liquid cooling or heating to be achieved with just one heat exchanger 15, eliminating the need for components (such as the heating tube 16) and saving costs.

[0058] In one embodiment, as shown in Figures 12 and 13, a heating mechanism is further provided, the heating mechanism including a heating tube 16, the heating tube 16 being provided inside the liquid storage tank 12 and electrically connected to the control assembly.

[0059] If it is necessary to heat the liquid in the liquid storage tank 12, the control assembly controls the compressor 11, condenser 13, and fan 14 to stop operation, and the control assembly operates the heating tube 16 to raise the liquid temperature in the liquid storage tank 12. The liquid whose temperature has risen flows into the first protector A through the third liquid inlet A1, giving the first protector A a heat padding function. The heating mechanism is controlled by the control assembly to raise the liquid temperature in the liquid storage tank 12, and as shown in Figure 29, the heating rate is: 2When using the first protective equipment A, the surface temperature of the first protective equipment A reaches 43°C within 8 minutes, the heating power is 150 watts, the heating amount reached is 150 watts, the heating effect is good, efficient and stable.

The first air pump 22 pressurizes the air that has entered the first trachea 174 and then transports it to the first protective device A, thereby filling the first protective device A with air. The first solenoid valve 23 is a two-way solenoid valve, which allows the first protective device A to be deflated. On the one hand, filling the first protective device A with air inflates it, making it fit more closely to the treatment area and improving the therapeutic effect of the cold therapy liquid / hot therapy liquid.

[0080] The problem that this embodiment aims to solve is the technical problem that the cooling effect of the cooling mechanism is insufficient and the efficiency is low.

[0081] The portable cold therapy system with selectable heating and compression therapy provided by the present invention has the following beneficial effects: the cooling mechanism is provided with a compressor 11, a condenser 13, a fan 14, and a heat exchanger 15. First, a high-temperature and high-pressure gas refrigerant is transported from the compressor 11 to the condenser 13 via the third pipe 173, and the refrigerant is liquefied after heat dissipation. At this time, since the temperature of the high-temperature and high-pressure gas refrigerant is high, the fan 14 is used to dissipate heat from the gas refrigerant in the condenser 13, and the gas refrigerant is liquefied by dissipating heat.

The liquid refrigerant passes through a capillary tube and is reduced in pressure, where it absorbs heat and evaporates in the condenser 13, and the gaseous refrigerant returns to the compressor 11. The installation of the four-way valve 18 allows liquid cooling or heating to be achieved with just one heat exchanger 15, reducing the number of components (such as the heating tube 16) and saving costs.

[0089] In a third aspect, as shown in Figures 20 to 25, 30 and 31, the present invention provides a portable cold therapy system capable of selectively performing heat therapy and compression therapy, which is applied to a first protective device A and includes a cooling mechanism, a liquid storage tank 12 and a control assembly, the cooling mechanism includes a compressor 11, a condenser 13, a fan 14 and a heat exchanger 15, the control assembly is electrically connected to the compressor 11 and the fan 14, and the compressor 11, the heat exchanger 15, the condenser 13 and the fan 14 are all provided outside the liquid storage tank 12, and the intake air of the compressor 11 The outlet of the compressor 11 is connected to the heat exchanger 15 through a first pipe 171, the heat exchanger 15 is connected to the condenser 13 through a second pipe 172, the condenser 13 is connected to the outlet of the compressor 11 through a third pipe 173, the first pipe 171 and the second pipe 172 are fluidly connected to each other, and the second pipe 172 and the third pipe 173 are fluidly connected to each other, so that the gas refrigerant in the compressor 11 passes through the condenser 13 and then through the heat exchanger 15 to produce a cooling effect, and the working surface of the fan 14 faces the condenser 13, The liquid storage tank 12 has a first liquid outlet 122, and the liquid in the liquid storage tank 12 flows into the first protective device A after passing through the heat exchanger 15 via the first liquid outlet 122, and the liquid in the first protective device A may flow into the first protective device A again after passing through the heat exchanger 15, or may flow into the liquid storage tank 12 via the first liquid outlet 122, and further comprises a heating mechanism, and the heating mechanism is electrically connected to the control assembly.

[0090] It should be noted that there may be one or more compressors 11, condensers 13, fans 14, and heat exchangers 15.

The liquid may be water, alcohol, antifreeze, or the like, and preferably, alcohol with a concentration of 10% is used.

[0093] In addition, a refrigerant addition port is provided at the branching point of the first pipe 171, so that the cooling temperature can be maintained when the cooling mechanism is in operation for a long period of time. When the cooling mechanism is used in a circulating manner for a long period of time, the heat exchange under ideal conditions cannot be fully achieved, and the expected cooling effect cannot be obtained. Therefore, a refrigerant can be added periodically to improve the cooling effect.

[0094] The first pipe 171 and the second pipe 172 fluidly penetrate each other, and the second pipe 172 and the third pipe 173 fluidly penetrate each other.

[0096] The portable cold therapy system with selectable heating and compression therapies provided by the present invention has the following beneficial effects: First, the cooling mechanism is provided with a compressor 11, a condenser 13, a fan 14, and a heat exchanger 15. A high-temperature, high-pressure gas refrigerant is transported from the compressor 11 to the condenser 13 via the third pipe 173. During this process, the high-temperature, high-pressure gas refrigerant is at a high temperature, and the fan 14 is used to dissipate heat from the gas refrigerant in the condenser 13, causing the gas refrigerant to liquefy. The liquid refrigerant is then transported from the condenser 13 to the heat exchanger 15 via the second pipe 172. The liquid refrigerant exchanges heat with the liquid in the heat exchanger 15, absorbing heat and evaporating, causing the temperature of the liquid to drop. The first pipe 171 is then used to transport the liquid refrigerant. The gas refrigerant is transported from the heat exchanger 15 to the compressor 11 via the first liquid outlet 122, and the gas refrigerant is compressed using the compressor 11. The heat exchanger 15 is installed outside the liquid storage tank 12. The liquid in the liquid storage tank 12 first flows into the heat exchanger 15 through the first liquid outlet 122 to be cooled and then flows back into the first protector A. The liquid in the first protector A flows back into the heat exchanger 15 to be cooled, or the liquid in the first protector A flows back into the liquid storage tank 12, giving the first protector A a cooling function. The remaining liquid in the liquid storage tank 12 does not participate in the circulation, which greatly improves the cooling efficiency and reduces power consumption. As shown in Figure 30, the cooling rate is: 2 Using the first protector, the surface temperature of the first protector reaches 5°C within 5 minutes, and the cooling power is 75 watts, achieving a cooling amount of 250 watts, with good cooling effect, high efficiency, stability, and low power consumption. Secondly, a heating mechanism is further provided, which includes a four-way valve 18 or a heating sheet 161. The control assembly controls the four-way valve 18 to change the flow direction or control the heat generation of the heating sheet 161, thereby increasing the liquid temperature in the heat exchanger. The heated liquid flows into the first protector through the third liquid inlet, giving the first protector a heat-matting function. As shown in Figure 31, the heating rate is: under the condition of an ambient temperature of 25-28°C, the area of ​​1 m 2The surface temperature of the first protective device reaches 43°C within 6 minutes, and the heating power is 75-150 watts, achieving a good heating effect with high efficiency and stability. Furthermore, the system is compact, lightweight, and easy to carry.

[0097] In one embodiment, the heat insulating device is further provided, and the heat insulating device is provided on the outside of the heat generating sheet 161. The heat insulating device may be a mica plate.

[0098] In one embodiment, as shown in Figures 23 to 25, the heat exchanger includes a third cooling plate 154, and a third air intake port 1541, a third exhaust port 1542, a fourth liquid inlet 1543 and a fourth liquid outlet 1544 are provided on the third cooling plate 154, and the third exhaust port 1542 is connected to the first pipe 171, the third air intake port 1541 is connected to the second pipe 172, the fourth liquid inlet 1543 is connected to the first liquid outlet 122, the fourth liquid outlet 1544 is connected to the third liquid inlet A1 of the first protector A, and the third liquid outlet A2 of the first protector A is connected to the first liquid outlet 122 and the fourth liquid inlet 1543.

[0099] The third cooling plate 154 is a welded plate type heat exchanger, and the liquid in the liquid storage tank 12 flows into the fourth liquid inlet 1543 through the first liquid inlet 121, and after being cooled in the welded plate type heat exchanger, flows into the first protective equipment A through the fourth liquid outlet 1544.

[0100] The refrigerant enters the third cooling plate 154 through the second pipe 172 and the third intake port 1541, then returns to the compressor 11 through the third exhaust port 1542 and the first pipe 171, cools the third cooling plate 154, and exchanges heat with the liquid in the third cooling plate 154, further lowering the liquid temperature.

[0101] In one embodiment, as shown in Figures 24 and 25, the device further includes a three-way joint 19, which has a first connection port 191, a second connection port 192, and a third connection port 193, and the first connection port 191 is connected to the first liquid outlet 122, the second connection port 192 is connected to the fourth liquid inlet 1543, and the third connection port 193 is connected to the third liquid outlet A2.

[0102] In one embodiment, as shown in Figures 24 and 25, the first liquid outlet 122 is connected to the first connection port 191 via a fifth pipe 178, the fourth liquid inlet 1543 is connected to the second connection port 192 via a sixth pipe 179, the fourth liquid outlet 1544 is connected to the third liquid inlet A1 via a seventh pipe 180, and the third liquid outlet A2 is connected to the third connection port 193 via an eighth pipe 181, Here, a water pump 21 is provided on the sixth pipe 179, and the water pump 21 is electrically connected to the control assembly. When the water pump 21 operates, the liquid in the storage tank 12 passes through the fifth pipe 178 and the sixth pipe 179, passes through the third cooling plate 154, and then flows into the first protector A through the seventh pipe 180. The liquid in the first protector A passes through the eighth pipe 181 and the sixth pipe 179, passes through the third cooling plate 154, and then flows into the first protector A again through the seventh pipe 180. When the water pump 21 stops, the liquid in the first protector A flows into the storage tank 12 through the eighth pipe 181 and the fifth pipe 178.

[0103] When the water pump 21 stops, the pressure inside the first protector A is high, so the liquid inside the first protector A flows into the liquid storage tank 12 via the eighth pipe 181 and the fifth pipe 178.

[0104] In one embodiment, a liquid level detector 61 is further provided in the storage tank 12, and a temperature sensor 62 is provided on the seventh pipe 180 (shown in Figure 24) or the eighth pipe 181 (shown in Figure 25), and both the liquid level detector 61 and the temperature sensor 62 are electrically connected to the control assembly.

[0105] In addition, a liquid level detector 61 is provided in the storage tank 12 and is used to detect the height or low of the liquid position, and a temperature sensor 62 is provided on the seventh pipe 180 or the eighth pipe 181 and is used to detect the temperature of the liquid that has entered the first protective device A or the liquid that has flowed out of the first protective device A, and the temperature is controlled by a control assembly to achieve an appropriate cold or hot padding effect.

[0106] In one embodiment, the second pipe 172 includes a flow-control device, which is arranged between the heat exchanger 15 and the condenser 13, and the condenser 13 includes a heat conduction tube, one end of which protrudes from the condenser 13 and is connected to the flow-control device, and the other end of the heat conduction tube protrudes from the condenser 13 and is connected to the compressor 11.

[0108] When the liquid refrigerant after heat dissipation passes through a capillary tube with a small diameter, the cross-sectional area of ​​the pipe is small and the flow rate is slow, so the pressure and temperature decrease. At this time, the liquid refrigerant, which has a high pressure immediately after being output from the condenser 13, is reduced in pressure as it passes through the capillary tube.

[0109] The heat transfer tube is a copper tube, which is curved and arranged in a "U" shape along the inner wall of the condenser 13. When high-temperature and high-pressure gas refrigerant enters the condenser section, the copper tube is installed in the pipe of the condenser section, and the heat of the gas refrigerant is absorbed by the copper tube and gradually dissipated to the surrounding environment. At the same time, the working surface of the fan 14 faces the position of the copper tube in the condenser 13, further promoting the refrigerant to dissipate heat and liquefy. After heat dissipation by the copper tube and the fan 14, the liquid refrigerant enters the capillary tube and is decompressed, and the liquid refrigerant is transported to the heat exchanger 15 via the second pipe 172.

[0111] As shown in Figures 24 and 25, the air that has entered the first trachea 174 via the first air pump 22 is pressurized and then transported to the first protective device A, thereby filling the first protective device A with air. The first solenoid valve 23 is a two-way solenoid valve, which discharges air from the first protective device A. On the one hand, filling the first protective device A with air causes it to expand, making it fit more closely to the treatment area and improving the therapeutic effect of the cold therapy liquid / hot therapy liquid. On the other hand, the combination of filling and discharging air allows the first protective device A to provide medical effects such as massage.

[0112] In one embodiment, a pressure reducing valve 27 and a pressure sensor 63 are further provided on the first trachea 174, and the pressure sensor 63 is electrically connected to the control assembly.

The remaining liquid in the liquid storage tank 12 does not participate in the circulation, which greatly improves the cooling efficiency and reduces power consumption. As shown in Figure 30, the cooling rate is: 2 Using the first protector A, the surface temperature of the first protector A reaches 5°C within 5 minutes, and the cooling power is 75 watts, achieving a cooling amount of 250 watts, with good cooling effect, high efficiency, stability, and low power consumption.
