Detailed Implementation

[0025] 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.

[0026] 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.

[0027] Please refer to the following: 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 control component 12, and a heating and cooling mechanism 13. The heating and cooling mechanism 13 includes a heat exchanger 131 and a semiconductor temperature conducting component 132. The heat exchanger 131 is connected to the liquid storage tank 11. The first contact surface 1321 of the semiconductor temperature conducting component 132 is connected to the heat exchanger 131. The semiconductor temperature conducting component 132 is electrically connected to the control component 12. The control component 12 is adapted to control the direction of the current flowing through the semiconductor temperature conducting component 132 so that the first contact surface 1321 is cooled or heated.

[0028] In this way, the multifunctional medical device 100 can exchange heat with the heat exchanger 131 through the semiconductor temperature-conducting component 132. When the first contact surface 1321 is cooled, the semiconductor temperature-conducting component 132 exchanges heat with the liquid in the heat exchanger 131, causing the liquid temperature to drop. The cooled liquid then flows through the protective garment 20, making it convenient for the user to apply a cold compress through the protective garment 20. When the first contact surface 1321 is heated, the semiconductor temperature-conducting component 132 exchanges heat with the liquid in the heat exchanger 131, causing the liquid temperature to rise. The heated liquid then flows through the protective garment 20, making it convenient for the user to apply a hot compress through the protective garment 20. This helps to enrich the functions of the multifunctional medical device 100 and helps to meet the user's needs in different scenarios.

[0029] Furthermore, the semiconductor temperature conducting component 132 can switch between cooling and heating functions by changing the direction of the current. The semiconductor temperature conducting component 132 has a fast response, which helps to improve the cooling or heating efficiency of the multifunctional medical device 100 and thus improve the working efficiency of the multifunctional medical device 100.

[0030] The liquid in the storage tank 11 and heat exchanger 131 is water, alcohol, antifreeze, etc. For example, the liquid is 10% alcohol, and the specific configuration can be set according to the actual situation. The storage tank 11 can be equipped with a liquid filling port to replenish the liquid in a timely manner. For example, the liquid filling port can be located on the side, top, or other positions of the storage tank 11, and the specific configuration can be set according to the actual situation.

[0031] The heat exchanger 131 can be a brazed plate heat exchanger 131, and the specific configuration can be determined according to the actual situation.

[0032] For example, the liquid in the storage tank 11 can flow into the heat exchanger 131 for cooling or heating through the outlet of the storage tank 11, and then flow into the protective garment 20. The liquid in the protective garment 20 can flow back into the heat exchanger 131 for cooling or heating, or the liquid in the protective garment 20 can flow back into the storage tank 11, so that the protective garment 20 has a cold compress or hot compress function, and the remaining liquid in the storage tank 11 will not participate in the circulation, which helps to improve the cooling or 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 cooling efficiency of the multifunctional medical device 100 is as follows: the surface temperature of the protective gear 20 reaches 10°C within 10 minutes, the cooling power is 50 watts, and the achieved cooling capacity is 45 watts; when the ambient temperature is 25-28°C and the area of ​​the protective gear 20 is 1m², the cooling efficiency is as follows: 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 42°C within 8 minutes, the heating power is 50 watts, and the achieved heating amount is 48 watts. Thus, the multifunctional medical device 100 has good heating and cooling effects, high efficiency, stability, and low power consumption. Furthermore, the multifunctional medical device 100 has a wide range of applications, which helps to improve the user experience.

[0033] In some embodiments, the semiconductor temperature-conducting component 132 includes at least one semiconductor temperature-conducting plate 1323, which is connected to the heat exchanger 131 and electrically connected to the control component 12.

[0034] This helps to improve the compactness of the heating and cooling mechanism 13. By controlling the direction of the current flowing through the semiconductor thermal conductive sheet 1323 through the control component 12, the first contact surface 1321 of the semiconductor thermal conductive sheet 1323 produces a cooling or heating effect, which helps to ensure the normal operation of the heating and cooling mechanism 13.

[0035] Wherein, "at least one" refers to one or more, for example, the semiconductor thermal conductive component 132 includes a semiconductor thermal conductive sheet 1323, such as Figure 3 As shown; for example, the semiconductor thermal conductive component 132 includes a semiconductor thermal conductive sheet 1323, such as Figure 4As shown; in other embodiments, the semiconductor temperature-conducting component 132 may also include other numbers of semiconductor temperature-conducting sheets 1323, which can be set according to the actual situation.

[0036] Please refer to the following: Figure 2 , Figure 3 and Figure 5 In some embodiments, the multifunctional medical device 100 also includes a housing 14, a piping assembly 15, and a water pump 16. The liquid storage tank 11, control assembly 12, heating and cooling mechanism 13, and piping assembly 15 are all mounted on the housing 14. This helps to improve the compactness of the multifunctional medical device 100.

[0037] In some embodiments, the piping assembly 15 is connected to the heating and cooling mechanism 13 and the liquid storage tank 11, and the water pump 16 is disposed on the piping assembly 15 and electrically connected to the control assembly 12.

[0038] Thus, the piping assembly 15 can accommodate the flow of liquid in the heating and cooling mechanism 13 and the storage tank 11, helping to ensure the normal operation of the heating and cooling mechanism 13. The water pump 16 can pump the liquid in the storage tank 11 to the heating and cooling mechanism 13, which helps to improve the efficiency of liquid circulation between the storage tank 11 and the heating and cooling mechanism 13, thereby helping to improve the heat exchange efficiency between the storage tank 11 and the heating and cooling mechanism 13.

[0039] In some embodiments, the piping assembly 15 includes a first pipe 151, a second pipe 152, a third pipe 153, and a tee connector 155. The water pump 16 is located on the second pipe 152. The tee connector 155 is connected to the first pipe 151, the second pipe 152, and the third pipe 153 respectively. The first pipe 151 is connected to the outlet end of the liquid storage tank 11, the second pipe 152 is connected to the inlet end of the heat exchanger 131, and the third pipe 153 is connected to the outlet end of the protective gear 20.

[0040] Thus, the three-way connector 155 helps ensure the circulation of liquid between the heating and cooling mechanism 13, the liquid storage tank 11, and the protective gear 20. The heating and cooling mechanism 13 and the liquid storage tank 11 can satisfy the circulation of liquid through the first pipe 151 and the second pipe 152. Since the water pump 16 is located in the second pipe 152, when the water pump 16 is turned off, the liquid in the protective gear 20 will flow back to the liquid storage tank 11 through the third pipe 153 and the first pipe 151 under pressure, instead of flowing back to the heat exchanger 131 through the second pipe 152. Therefore, the third pipe 153 helps ensure that the liquid in the protective gear 20 can flow back to the liquid storage tank 11, which helps to ensure the circulation between the protective gear 20 and the liquid in the liquid storage tank 11.

[0041] In some embodiments, the piping assembly 15 may further include a fourth piping 154, which is connected to the liquid outlet of the heat exchanger 131 and the liquid inlet of the guard 20, so that the liquid after heat exchange in the heat exchanger 131 can enter the guard 20 through the fourth piping 154.

[0042] For example, when the water pump 16 is working, the liquid in the storage tank 11 enters the heat exchanger 131 through the first pipe 151 and the second pipe 152, and after heat exchange in the heat exchanger 131, it flows into the protective gear 20 through the fourth pipe 154; when the water pump 16 is turned off, the liquid in the protective gear 20 flows back to the storage tank 11 through the third pipe 153 and the first pipe 151, thereby ensuring the normal operation of the multifunctional medical device 100.

[0043] When the water pump 16 is turned off, due to the high pressure inside the protective gear 20, the liquid in the protective gear 20 will flow into the storage tank 11 through the third pipe 153 and the first pipe 151.

[0044] See Figure 5 In some embodiments, the multifunctional medical device 100 also includes a temperature sensor 17 disposed on the heat exchanger 131, the temperature sensor 17 being electrically connected to the control component 12, and the temperature sensor 17 being adapted to detect the temperature of the liquid within the heat exchanger 131.

[0045] Thus, the temperature sensor 17 can detect the temperature of the liquid in the heat exchanger 131 so that the temperature can be controlled by the control component 12, which helps to ensure that the liquid in the heat exchanger 131 is at a suitable temperature, thereby ensuring that the liquid entering the protective gear 20 has a suitable temperature, thus helping to ensure the cold or hot compress effect of the protective gear 20.

[0046] In some embodiments, the multifunctional medical device 100 also includes an insulation element that covers the outer periphery of the heat exchanger 131.

[0047] This helps to isolate the heat exchanger 131 from the external environment, reducing the impact of the external environment on the heat exchanger 131 and achieving a heat preservation effect.

[0048] The insulation component can be mica sheet or other insulation structure, and the specific configuration can be determined according to the actual situation.

[0049] Please refer to the following: Figure 3 and Figure 6 In some embodiments, the heating and cooling mechanism 13 further includes a heat dissipation component 19, which contacts the second contact surface 1322 of the semiconductor temperature-conducting component 132, and is electrically connected to the control component 12. The first contact surface 1321 is a cooling surface, and the second contact surface 1322 is a heating surface.

[0050] In this way, the heat dissipation component 19 can cool the semiconductor temperature conduction component 132 through the second contact surface 1322, which helps to reduce the situation where the semiconductor temperature conduction component 132 is too hot, helps to prevent the semiconductor temperature conduction component 132 from malfunctioning or failing due to excessive temperature, and improves the cooling efficiency of the first contact surface 1321.

[0051] In some embodiments, the heat dissipation assembly 19 includes a microchannel heat sink 191 and a fan 192. The fan 192 is electrically connected to the control assembly 12, the microchannel heat sink is connected to the second contact surface, and the working surface of the fan 192 faces the microchannel heat sink 191.

[0052] In this way, the fan 192 can accelerate the airflow in the microchannel heat sink 191, thereby removing the hot air in the microchannel heat sink 191, causing the temperature of the microchannel heat sink 191 to drop, and in turn causing the temperature of the second contact surface 1322 to drop. This helps to improve the heat dissipation efficiency of the microchannel heat sink 191 for the semiconductor thermal conductive component 132, and helps to reduce the situation where the temperature of the semiconductor thermal conductive component 132 is too high.

[0053] The housing 14 may be provided with multiple heat dissipation vents, which are opposite to the heat dissipation component 19, so that the hot air of the heat dissipation component 19 can be discharged through the multiple heat dissipation vents, thereby better keeping each device in a suitable temperature environment.

[0054] In some embodiments, the microchannel radiator 191 is provided with a gas chamber 1911, and the gas chamber 1911 is provided with a refrigerant filling port 1912.

[0055] In this way, liquid refrigerant can be added through the refrigerant filling port 1912. The liquid refrigerant exchanges heat with the microchannel heat sink 191 in the gas chamber 1911, causing the temperature of the microchannel heat sink 191 to drop, thereby cooling the second contact surface 1322 of the semiconductor thermal conductive component 132. In addition, the microchannel heat sink 191 has a simple structure, which helps to simplify the structure of the heat dissipation component 19 and facilitates manufacturing.

[0056] Revisit Figure 1 In some embodiments, the multifunctional medical device 100 also includes an air pump (not shown), a solenoid valve, and an air tube (not shown). The air tube is connected to the air pump and the protective garment 20. The solenoid valve is disposed on the air tube. The air pump and the solenoid valve are electrically connected to the control component 12. The protective garment 20 has an inflated state and an vented state. When the protective garment 20 is in the inflated state, the air pump inflates the protective garment 20. When the protective garment 20 is in the vented state, the protective garment 20 vents through the solenoid valve.

[0057] 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.

[0058] For example, when the protective gear 20 is in an inflated state, the control component 12 controls the air pump to inflate the protective gear 20, causing the protective gear 20 to expand to fit the treatment site more closely, which helps to improve the therapeutic effect of the cold / heat therapy fluid; when the protective gear 20 is in an deflated state, the control component 12 controls the solenoid valve to deflate the protective gear 20, causing the protective gear 20 to contract away from and relax the treatment site, which also helps to improve the therapeutic effect of the cold / heat therapy fluid.

[0059] In some embodiments, the control component 12 also includes a battery installed in the housing 14, the battery being adapted to power the semiconductor temperature-conducting component 132. Thus, the multifunctional medical device 100 can also be used normally when the application scenario is outdoors. Furthermore, by rationally arranging the positions of the components within the multifunctional medical device 100, its overall size can be miniaturized, thereby facilitating user portability.

[0060] The multifunctional medical device 100 provided in this embodiment of the present invention includes a heating and cooling mechanism 13 comprising a heat exchanger 131 and a semiconductor temperature conducting component 132. The heat exchanger 131 is connected to a liquid storage tank 11. The first contact surface 1321 of the semiconductor temperature conducting component 132 is connected to the heat exchanger 131. The semiconductor temperature conducting component 132 is electrically connected to a control component 12. The control component 12 is adapted to control the direction of the current flowing through the semiconductor temperature conducting component 132 so that the first contact surface 1321 is cooled or heated. Thus, the multifunctional medical device 100 can exchange heat with the heat exchanger 131 through the semiconductor temperature-conducting component 132. When the first contact surface 1321 is cooled, the semiconductor temperature-conducting component 132 exchanges heat with the liquid in the heat exchanger 131, causing the liquid temperature to drop. The cooled liquid then flows through the protective garment 20, making it convenient for the user to apply a cold compress through the protective garment 20. When the first contact surface 1321 is heated, the semiconductor temperature-conducting component 132 exchanges heat with the liquid in the heat exchanger 131, causing the liquid temperature to rise. The heated liquid then flows through the protective garment 20, making it convenient for the user to apply a hot compress through the protective garment 20. This helps to enrich the functions of the multifunctional medical device 100 and helps to meet the user's needs in different scenarios. In addition, the semiconductor temperature-conducting component 132 can switch between cooling and heating functions by changing the direction of the current. The semiconductor temperature-conducting component 132 has a fast response, which helps to improve the cooling or heating efficiency of the multifunctional medical device 100 and improve the working efficiency of the multifunctional medical device 100.
