Detailed Implementation

[0027] To enable those skilled in the art to better understand the embodiments of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] Medical devices using related technologies typically have a single heat exchanger, integrating both cooling and heating functions. This can lead to interference between the cooling and heating functions, resulting in inaccurate temperature control.

[0030] See Figures 1 to 3 This utility model provides a multifunctional medical device 100, which is applied to a protective garment 20. The multifunctional medical device 100 includes a liquid storage tank 11, a cooling mechanism 12, and a heating mechanism 13. The cooling mechanism 12 includes a connected cooling component 121 and a first heat exchanger 122. The first heat exchanger 122 is connected to the liquid storage tank 11, and the cooling component 121 is adapted to cool the first heat exchanger 122. The heating mechanism 13 includes a connected heating component 131 and a second heat exchanger 132. The second heat exchanger 132 is connected to the liquid storage tank 11, and the heating component 131 is adapted to heat the second heat exchanger 132.

[0031] Thus, the multifunctional medical device 100 can cool the first heat exchanger 122 via the cooling component 121, thereby cooling the liquid flowing through the first heat exchanger 122 and lowering its temperature. The cooled liquid then flows through the protective garment 20, allowing the user to apply a cold compress. The multifunctional medical device 100 can also heat the second heat exchanger 132 via the heating component 131, thereby heating the liquid flowing through the second heat exchanger 132 and raising its temperature. The heated liquid then flows through the protective garment 20, allowing the user to apply a hot compress. The multifunctional medical device 100 can perform both cold and hot compresses, enriching its functionality and helping to meet the user's needs in different scenarios.

[0032] Furthermore, the first heat exchanger 122 and the second heat exchanger 132 are separately configured. The cooling component 121 can independently cool the first heat exchanger 122, and the heating component 131 can independently heat the second heat exchanger 132. This helps reduce interference between the cooling and heating processes caused by the integration of the first and second heat exchangers 122 and 132, improves the cooling efficiency and stability of the cooling mechanism 12, and also improves the heating efficiency and stability of the heating mechanism 13. It also helps reduce the power consumption of the multifunctional medical device 100, thus better meeting the user's needs. The separate configuration of the first and second heat exchangers 122 also allows the cooling component 121 to pre-cool the first heat exchanger 122 and the heating component 131 to pre-heat the second heat exchanger 132, enabling the protective garment 20 of the multifunctional medical device 100 to quickly reach the temperature for cold or hot compresses, allowing for immediate use when the user needs treatment, thus better meeting the user's needs.

[0033] For example, the liquid in the storage tank 11 can flow into the first heat exchanger 122 for cooling through the outlet of the storage tank 11 before flowing into the protective garment 20. The liquid in the protective garment 20 can then flow back into the first heat exchanger 122 for cooling, or the liquid in the protective garment 20 can flow back into the storage tank 11, so that the protective garment 20 has a cooling function. The remaining liquid in the storage tank 11 will not participate in the circulation, which helps improve cooling efficiency and reduce power consumption. This is suitable when the ambient temperature is 25-28℃ and the area of ​​the protective garment 20 is 1m². 2 At that time, the cooling efficiency of the multifunctional medical device 100 is as follows: the surface temperature of the protective gear 20 reaches 5°C within 3 minutes, the cooling power is 75 watts, and the cooling capacity is 250 watts. The cooling mechanism 12 has high cooling efficiency, stable cooling and low cooling power, and is simple and practical.

[0034] For example, the liquid in the storage tank 11 can flow through the outlet of the storage tank 11 into the second heat exchanger 132 for heating before flowing into the protective garment 20. The liquid in the protective garment 20 can then flow back into the second heat exchanger 132 for heating, or the liquid in the protective garment 20 can flow back into the storage tank 11, thus enabling the protective garment 20 to have a heat therapy function. The remaining liquid in the storage tank 11 will not participate in the circulation, which helps improve heating efficiency and reduce power consumption. This is suitable when the ambient temperature is 25-28℃ and the area of ​​the protective garment 20 is 1m². 2 At that time, the heating efficiency of the multifunctional medical device 100 is as follows: the surface temperature of the protective gear 20 reaches 43°C within 5 minutes, the heating power is 150 watts, and the heating amount reached is 150 watts. The heating mechanism 13 has high heating efficiency, stable heating and low heating power, and is simple and practical.

[0035] The liquid in the storage tank 11, the first heat exchanger 122, and the second heat exchanger 132 is water, alcohol, antifreeze, etc. For example, the liquid is 10% alcohol, and the specific configuration can be adjusted according to actual conditions. The storage tank 11 may be equipped with a filling port to replenish the liquid in a timely manner. For example, the filling port may be located on the side, top, or other positions of the storage tank 11, depending on the actual conditions.

[0036] The first heat exchanger 122 and the second heat exchanger 132 can be brazed plate heat exchangers, and the specific configuration can be determined according to the actual situation.

[0037] In some embodiments, the multifunctional medical device 100 also includes a control component electrically connected to the cooling component 121 and the heating component 131, respectively.

[0038] This helps to control the working status of the cooling component 121 and the heating component 131 in real time, thereby accurately adjusting the working status of the cooling component 121 and the heating component 131.

[0039] In some embodiments, a liquid level detector is provided inside the liquid storage tank 11, and the liquid level detector is electrically connected to the control component.

[0040] In this way, the liquid level in the storage tank 11 can be detected in real time by the liquid level detector to ensure that there is enough liquid in the storage tank 11 and reduce the situation where the multifunctional medical device 100 cannot work properly due to insufficient liquid in the storage tank 11.

[0041] See Figures 2 to 4 In some embodiments, the refrigeration assembly 121 includes a compressor 1211, a condenser 1212, and a heat sink 1213. The refrigerant outlet of the first heat exchanger 122 is connected to the refrigerant inlet of the compressor 1211, the refrigerant outlet of the compressor 1211 is connected to the refrigerant inlet of the condenser 1212, and the refrigerant outlet of the condenser 1212 is connected to the refrigerant inlet of the first heat exchanger 122. The working surface of the heat sink 1213 faces the condenser 1212. The heat sink 1213 can be a fan. The first heat exchanger 122, the compressor 1211, and the condenser 1212 can be connected by pipes. A control assembly is electrically connected to the compressor 1211 and the heat sink 1213 to control the start and stop of the compressor 1211 and the heat sink 1213 in real time.

[0042] In this way, the refrigerant can circulate between the first heat exchanger 122, the compressor 1211, and the condenser 1212 to cool the first heat exchanger 122, thereby cooling the liquid flowing through the first heat exchanger 122. This reduces the temperature of the liquid flowing through the first heat exchanger 122 to a suitable temperature, ensuring that the temperature of the liquid flowing through the protective cover 20 meets the user's requirements. The heat sink 1213 can also cool the condenser 1212, helping to reduce the temperature of the condenser 1212 and reducing the risk of damage due to excessively high temperature.

[0043] For example, a high-temperature, high-pressure gaseous refrigerant can be transported from the compressor 1211 to the condenser 1212 via a pipeline. At this time, the high-temperature, high-pressure gaseous refrigerant has a high temperature. The heat sink 1213 dissipates heat from the gaseous refrigerant in the condenser 1212, causing the gaseous refrigerant to release heat and liquefy. Then, the liquid refrigerant is transported from the condenser 1212 to the first heat exchanger 122 via a pipeline. The liquid refrigerant exchanges heat with the liquid in the first heat exchanger 122, absorbing heat from the liquid and vaporizing, while the liquid temperature decreases. Then, the gaseous refrigerant is transported from the first heat exchanger 122 to the compressor 1211 via a pipeline, where the compressor 1211 compresses the gaseous refrigerant. The first heat exchanger 122 is located outside the liquid storage tank 11. The liquid in the liquid storage tank 11 flows into the first heat exchanger 122 through the liquid outlet of the liquid storage tank 11 for cooling before flowing into the protective garment 20. The liquid in the protective garment 20 can flow back into the first heat exchanger 122 for cooling, or the liquid in the protective garment 20 can flow back into the liquid storage tank 11, so that the protective garment 20 has a cold compress function.

[0044] The pipe between the first heat exchanger 122 and the compressor 1211 may be equipped with a refrigerant charging port, so as to facilitate timely replenishment of refrigerant, so as to maintain the refrigeration temperature and improve the refrigeration effect during long-term operation of the refrigeration mechanism 12.

[0045] The pipe between the condenser 1212 and the first heat exchanger 122 may be equipped with a throttling device, which may be a capillary tube, a throttling valve or other throttling and pressure-reducing device. When the liquid refrigerant flowing out of the condenser 1212 passes through the throttling device, the flow speed slows down, thereby reducing the pressure of the liquid refrigerant and also reducing its temperature.

[0046] In some embodiments, the second heat exchanger 132 is spaced apart from the first heat exchanger 122 along the length X of the multifunctional medical device 100, and the second heat exchanger 132 is located on the side of the first heat exchanger 122 away from the cooling component 121.

[0047] This helps reduce the interference of the refrigeration component 121 on the second heat exchanger 132, and also helps reduce the mutual interference between the first heat exchanger 122 and the second heat exchanger 132. It also helps improve the accuracy of temperature control during the refrigeration process of the refrigeration mechanism 12, the accuracy of temperature control during the heating process of the heating mechanism 13, and the accuracy of temperature control of the multifunctional medical device 100. Furthermore, it helps to rationally arrange the positions of the first heat exchanger 122 and the second heat exchanger 132, and improves the compactness of the structure of the multifunctional medical device 100.

[0048] In some embodiments, the heating assembly 131 includes at least one heating element 1311, which is attached to the outer side of the second heat exchanger 132. A control assembly is electrically connected to the heating element 1311 to control the heating of the heating element 1311 in real time.

[0049] This helps the heating element 1311 to directly transfer heat to the second heat exchanger 132, thereby heating the liquid flowing through the second heat exchanger 132, which helps to improve the heating efficiency of the liquid flowing through the second heat exchanger 132, and also helps to improve the compactness of the heating mechanism 13 structure.

[0050] Wherein, "at least one" refers to one or more. For example, heating assembly 131 includes one heating element 1311, which is attached to one side of the second heat exchanger 132, or one heating element 1311 surrounds and is attached to the periphery of the second heat exchanger 132; for another example, heating assembly 131 includes two heating elements 1311, which are respectively attached to the same side or different sides of the second heat exchanger 132; for yet another example, heating assembly 131 includes three heating elements 1311, which are respectively attached to the same side or different sides of the second heat exchanger 132; in other embodiments, heating assembly 131 may also include other numbers of heating elements 1311, which can be set according to actual conditions.

[0051] In some embodiments, the heating assembly 131 further includes a heat insulation element that is attached to the outside of the heating element 1311.

[0052] This helps to isolate the heating element 1311 from the external environment, reduces heat loss from the heating element 1311, and provides insulation, thereby improving the heating effect of the heating element 1311 on the second heat exchanger 132.

[0053] The insulation component can be mica sheet or other insulation structure, and the specific configuration can be determined according to the actual situation.

[0054] See Figures 4 to 7 In some embodiments, the multifunctional medical device 100 further includes a multi-way solenoid valve 14. The multi-way solenoid valve 14 has a first heat exchanger inlet port 141 and a second heat exchanger inlet port 142. The first heat exchanger inlet port 141 is connected to the inlet end of the first heat exchanger 122, and the second heat exchanger inlet port 142 is connected to the inlet end of the second heat exchanger 132. A control component is electrically connected to the multi-way solenoid valve 14 to selectively open or close the first heat exchanger inlet port 141 and the second heat exchanger inlet port 142. The first heat exchanger inlet port 141 and the second heat exchanger inlet port 142 are located on the same side of the multi-way solenoid valve 14.

[0055] Thus, the multi-port solenoid valve 14 can integrate multiple interfaces, which facilitates the connection of multiple devices, allows for the arrangement of the first heat exchanger 122 and the second heat exchanger 132 from the same side, and improves the compactness of the structure. Liquid in the multifunctional medical device 100 can enter the first heat exchanger 122 through the first heat exchanger inlet port 141, and liquid in the multifunctional medical device 100 can also enter the second heat exchanger 132 through the second heat exchanger inlet port 142, thus meeting the liquid inlet requirements of the first heat exchanger 122 and the second heat exchanger 132.

[0056] The first heat exchanger inlet port 141 and the second heat exchanger inlet port 142 can be selectively opened or closed, so that the multi-way solenoid valve 14 can selectively enter the first heat exchanger 122 or the second heat exchanger 132 according to the actual situation, so as to ensure the normal operation of the multi-functional medical device 100.

[0057] In some embodiments, the multifunctional medical device 100 further includes a water pump 15, and a multi-way solenoid valve 14 is also provided with a water pump outlet interface 143. The inlet end of the water pump 15 is connected to the outlet end of the storage tank 11, and the outlet end of the water pump 15 is connected to the water pump outlet interface 143. A control component is electrically connected to the water pump 15 to control the start and stop of the water pump 15 in real time.

[0058] Thus, when the liquid inlet 141 of the first heat exchanger is open, the water pump 15 can pump the liquid in the storage tank 11 to the first heat exchanger 122, which helps to improve the efficiency of liquid circulation between the storage tank 11 and the first heat exchanger 122, thereby helping to improve the heat exchange efficiency between the storage tank 11 and the first heat exchanger 122. When the liquid inlet 142 of the second heat exchanger is open, the water pump 15 can pump the liquid in the storage tank 11 to the second heat exchanger 132, which helps to improve the efficiency of liquid circulation between the storage tank 11 and the second heat exchanger 132, thereby helping to improve the heat exchange efficiency between the storage tank 11 and the second heat exchanger 132.

[0059] See Figures 4 to 7 In some embodiments, the multifunctional medical device 100 further includes a first multi-port connector 21, which is provided with a liquid tank outlet interface 211, a water pump inlet interface 212, and a protective gear outlet interface 213. The liquid tank outlet interface 211 is connected to the outlet end of the liquid tank 11, the water pump inlet interface 212 is connected to the inlet end of the water pump 15, and the protective gear outlet interface 213 is connected to the outlet end of the protective gear 20.

[0060] Thus, when the water pump 15 is working, the liquid in the storage tank 11 can enter the first heat exchanger 122 or the second heat exchanger 132 through the water pump 15, and the liquid flowing out of the protective gear 20 can re-enter the first heat exchanger 122 or the second heat exchanger 132 through the water pump 15. The liquid flowing out of the protective gear 20 will not flow back directly into the storage tank 11, that is, the remaining liquid in the storage tank 11 does not participate in the circulation, which helps to save power consumption and helps to improve the heating or cooling efficiency of the multifunctional medical device 100.

[0061] When the water pump 15 stops working, the liquid flowing out of the protective gear 20 can flow back into the storage tank 11.

[0062] In some embodiments, the multifunctional medical device 100 further includes a second multi-port connector 16. The second multi-port connector 16 is provided with a first heat exchanger outlet port 161, a second heat exchanger outlet port 162, and a protective gear inlet port 163. The first heat exchanger outlet port 161 is connected to the outlet end of the first heat exchanger 122, the second heat exchanger outlet port 162 is connected to the outlet end of the second heat exchanger 132, and the protective gear inlet port 163 is connected to the inlet end of the protective gear 20. The first heat exchanger outlet port 161 and the second heat exchanger outlet port 162 are located on the same side of the second multi-port connector 16, and the protective gear inlet port 163 is located on the other side of the second multi-port connector 16.

[0063] Thus, the second multi-port connector 16 can integrate multiple interfaces, facilitating the connection of multiple devices, enabling the arrangement of the first heat exchanger 122 and the second heat exchanger 132 from the same side, improving the structural compactness, and reducing the space occupied by the first heat exchanger 122 and the second heat exchanger 132 due to their shared location, which could lead to insufficient space for mutual interference. Liquid in the first heat exchanger 122 can enter the protective device 20 through the first heat exchanger outlet port 161, and liquid in the second heat exchanger 132 can enter the protective device 20 through the second heat exchanger outlet port 162, thus meeting the liquid inlet requirements of the protective device 20 under different conditions.

[0064] In some embodiments, the second multi-port connector 16 is further provided with a temperature sensing interface 164 and a pressure sensing interface 165. The multifunctional medical device 100 also includes a temperature sensing element 17 and a pressure sensing element 18. The temperature sensing element 17 is connected to the temperature sensing interface 164, and the pressure sensing element 18 is connected to the pressure sensing interface 165. The temperature sensing element 17 can be a temperature sensor, and the pressure sensing element 18 can be a water pressure sensor. The temperature sensing interface 164 and the pressure sensing interface 165 are located on different sides of the second multi-port connector 16, respectively, as are the liquid outlet interface 161 of the first heat exchanger and the liquid inlet interface 163 of the protective gear.

[0065] Thus, the temperature sensor 17 can detect the temperature of the liquid flowing through the second multi-port connector 16 in real time, helping to ensure that the liquid flowing through the second multi-port connector 16 is at a suitable temperature, thereby ensuring that the liquid entering the protective garment 20 has a suitable temperature, and thus helping to ensure the cold or hot compress effect of the protective garment 20. The pressure sensor 18 can detect the water pressure in the second multi-port connector 16 in real time, thereby ensuring that the second multi-port connector 16 has a suitable water pressure, helping to reduce the possibility of overpressure in the second multi-port connector 16 affecting the pressure of other pipelines.

[0066] See Figure 7 and Figure 8 In some embodiments, the multifunctional medical device 100 further includes an air pump 191, a two-way solenoid valve 193, and an air tube 192. The air tube 192 is connected to the air pump 191 and the protective garment 20. The two-way solenoid valve 193 is disposed on the air tube 192. The protective garment 20 has an inflated state and an deflated state. When the protective garment 20 is in the inflated state, the air pump 191 inflates the protective garment 20. When the protective garment 20 is in the deflated state, the protective garment 20 deflates through the two-way solenoid valve 193. A control component is electrically connected to the air pump 191 and the two-way solenoid valve 193.

[0067] Thus, the multifunctional medical device 100 can achieve massage by combining the inflated and deflated states of the protective gear 20, thereby better enriching the functions of the multifunctional medical device 100.

[0068] For example, when the protective garment 20 is in an inflated state, the control component controls the air pump 191 to inflate the protective garment 20, causing the protective garment 20 to expand to fit the treatment site more closely, which helps to improve the therapeutic effect of the cold / heat therapy liquid; when the protective garment 20 is in an deflated state, the control component controls the two-way solenoid valve 193 to deflate the protective garment 20, causing the protective garment 20 to contract away from and relax the treatment site. The combination of inflation and deflation enables the protective garment to have medical effects such as massage.

[0069] In some embodiments, the air pipe 192 is also provided with a pressure relief valve 194 and a pressure sensor 195, the pressure sensor 195 being electrically connected to the control component.

[0070] Thus, the air pressure sensor 195 can detect the air pressure in the trachea 192. When the air pressure in the trachea 193 is too high, the control component can control the two-way solenoid valve 193 to release the pressure, or physically release the pressure through the pressure relief valve 194, thereby preventing the trachea 192 from bursting due to excessive air pressure.

[0071] In some embodiments, the multifunctional medical device 100 also includes a battery, which is installed in the housing to provide the electrical power required by the devices in the multifunctional medical device 100. Thus, the multifunctional medical device 100 can also be used normally when used outdoors. Furthermore, by rationally arranging the positions of the devices in the multifunctional medical device 100, the overall size of the multifunctional medical device 100 can be miniaturized, thereby making it easier for users to carry.

[0072] In summary, the multifunctional medical device 100 provided by this embodiment of the invention is applied to the protective gear 20. The cooling mechanism 12 of the multifunctional medical device 100 includes a cooling component 121 and a first heat exchanger 122 connected together. The first heat exchanger 122 is connected to the liquid storage tank 11, and the cooling component 121 is adapted to cool the first heat exchanger 122. The heating mechanism 13 includes a heating component 131 and a second heat exchanger 132 connected together. The second heat exchanger 132 is connected to the liquid storage tank 11, and the heating component 131 is adapted to heat the second heat exchanger 132. Thus, the multifunctional medical device 100 can cool the first heat exchanger 122 via the cooling component 121, thereby cooling the liquid flowing through the first heat exchanger 122 and lowering its temperature. The cooled liquid then flows through the protective garment 20, allowing the user to apply a cold compress. The multifunctional medical device 100 can also heat the second heat exchanger 132 via the heating component 131, thereby heating the liquid flowing through the second heat exchanger 132 and raising its temperature. The heated liquid then flows through the protective garment 20, allowing the user to apply a hot compress. The multifunctional medical device 100 can perform both cold and hot compresses, enriching its functionality and helping to meet the user's needs in different scenarios. Furthermore, the first heat exchanger 122 and the second heat exchanger 132 are separately configured. The refrigeration component 121 can independently refrigerate the first heat exchanger 122, and the heating component 131 can independently heat the second heat exchanger 132. This helps to reduce the mutual interference between the refrigeration and heating processes caused by the integration of the first heat exchanger 122 and the second heat exchanger 132. It also helps to improve the refrigeration efficiency and stability of the refrigeration mechanism 12, as well as the heating efficiency and stability of the heating mechanism 13, and helps to reduce the power consumption of the multifunctional medical device 100, thereby better meeting the user's needs.
