Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a portable cryotherapy system and device with optional compression therapy. Background Art

[0002] Cryotherapy systems and devices are widely used in the fields of sports rehabilitation, pain relief, swelling elimination, wound healing, etc.

[0003] The existing cryotherapy systems and devices mainly use semiconductor refrigeration, and the cryotherapy systems and devices using semiconductor refrigeration have the following disadvantages:

[0004] 1. When using semiconductor refrigeration, the temperature control of the cryotherapy device is limited. If it is not properly controlled, it may cause excessive heat loss of the chip and even lose the cooling effect.

[0005] 2. The refrigeration effect of semiconductor refrigeration is easily affected by the ambient temperature. When the ambient temperature exceeds a specific range, it is difficult to effectively absorb heat, resulting in a decrease in the cooling effect.

[0006] 3. In general, semiconductor refrigeration fixes the refrigeration chip on the heat sink and controls the operation of the chip through current to take away heat. When current passes through the chip, the N-type semiconductor absorbs the surrounding heat, while the P-type semiconductor releases heat. This makes one side of the chip in a low-temperature state and the other side in a high-temperature state. By connecting a water pipe and flowing water through the low-temperature surface of the chip, the refrigeration is realized by using electric energy. This method has high power consumption and a large device volume.

[0043] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments.

Therefore, they do not have any substantial technical significance. Any modification of the structure, change in the proportional relationship, or adjustment of the size, without affecting the efficacy that this application can produce and the purpose that can be achieved, should still fall within the scope covered by the technical content disclosed in this application.

[0047] In a first aspect, as shown in Figures 1-9 the present utility model provides a portable cryotherapy system with optional compression therapy, which is applied to a protective device A and includes a refrigeration mechanism, a liquid storage tank 12, and a control component; the refrigeration mechanism includes: a compressor 11, a condenser 13, a fan 14, and a heat exchanger 15; the control component is electrically connected to the compressor 11, the condenser 13, and the fan 14 respectively; the compressor 11, the heat exchanger 15, the condenser 13, and the fan 14 are all arranged outside the liquid storage tank 12; the intake port of the compressor 11 is connected to the heat exchanger 15 through a first pipeline 161; the heat exchanger 15 is connected to the condenser 13 through a second pipeline 162; the condenser 13 is connected to the outlet of the compressor 11 through a third pipeline 163; the first pipeline 161 and the second pipeline 162 are in fluid communication, and the second pipeline 162 and the third pipeline 163 are in fluid communication; the working surface of the fan 14 faces the condenser 13;

[0048] Among them, the liquid storage tank 12 includes a liquid storage tank liquid outlet 121; the heat exchanger is provided with a heat exchanger intake port 151, a heat exchanger outlet 152, a heat exchanger liquid inlet 153, and a heat exchanger liquid outlet 154; the heat exchanger outlet 152 is connected to the first pipeline 161, the heat exchanger intake port 151 is connected to the second pipeline 162, the heat exchanger liquid inlet 153 is connected to the liquid storage tank liquid outlet 121, the heat exchanger liquid outlet 154 is connected to the protective device liquid inlet A1 of the protective device A, and the protective device liquid outlet A2 of the protective device A is connected to the liquid storage tank liquid outlet 121 and the heat exchanger liquid inlet 153; the liquid in the liquid storage tank 12 can flow through the heat exchanger 15 through the liquid storage tank liquid outlet 121 and the heat exchanger liquid inlet 153, and then flow into the protective device A through the heat exchanger liquid outlet 154 and the protective device liquid inlet A1; the liquid in the protective device A can flow through the heat exchanger 15 through the protective device liquid outlet A2 and the heat exchanger liquid inlet 153 and then flow into the protective device A again, or flow into the liquid storage tank 12 through the protective device liquid outlet A2 and the liquid storage tank liquid outlet 121.

[0049] It should be noted that the compressor 11, the condenser 13, the fan 14, and the heat exchanger 15 can each be one or more. A plurality of the compressors 11 are arranged in series; a plurality of the condensers 13 are arranged in series, and the working surface of each fan 14 faces each condenser 13; a plurality of the heat exchangers 15 are arranged in series.

[0050] It should be noted that the liquid is water, alcohol, antifreeze, etc.; preferably, alcohol with a concentration of 10% is used.

[0051] It should be noted that the first pipeline 161 is branched with a refrigerant addition port to maintain the refrigeration temperature during the long-term operation of the refrigeration mechanism; when the refrigeration mechanism is used in long-term circulation, it is not possible to completely achieve the heat exchange in the ideal state, and the refrigeration effect cannot reach the expected value. Refrigerant can be added regularly to improve the refrigeration effect.

[0052] It should be noted that the heat exchanger 15 is a brazed plate heat exchanger. The liquid in the liquid storage tank 12 flows into the heat exchanger inlet 153 through the liquid outlet 121 of the liquid storage tank. After being cooled in the brazed plate heat exchanger, the liquid then flows into the protector A through the heat exchanger outlet 154.

[0053] It is worth noting that the first pipeline 161 is in fluid communication with the second pipeline 162, and the second pipeline 162 is in fluid communication with the third pipeline 163. In fact, the first pipeline 161, the second pipeline 162, and the third pipeline 163 are all on the same pipeline.

[0054] It is worth noting that the refrigerant enters the heat exchanger 15 through the second pipeline 162 and the heat exchanger inlet 151, and then returns to the compressor 11 through the heat exchanger outlet 152 and the first pipeline 161, so as to cool down the heat exchanger 15 and exchange heat with the liquid in the heat exchanger 15, thereby reducing the liquid temperature.

[0055] The problem to be solved in this embodiment lies in the technical problems of insufficient cooling effect and low efficiency of the refrigeration mechanism.

[0056] A portable cryotherapy system with an optional compression therapy provided by the present utility model has the beneficial effects as follows: The refrigeration mechanism is provided with a compressor 11, a condenser 13, a fan 14 and a heat exchanger 15. The high-temperature and high-pressure gaseous refrigerant is transported from the compressor 11 to the condenser 13 through the third pipeline 163. At this time, the high-temperature and high-pressure gaseous refrigerant has a relatively high temperature. The fan 14 is used to dissipate heat from the gaseous refrigerant in the condenser 13, and the gaseous refrigerant releases heat and liquefies. The liquid refrigerant is transported from the condenser 13 to the heat exchanger 15 through the second pipeline 162. The liquid refrigerant exchanges heat with the liquid in the heat exchanger 15, vaporizes after absorbing the heat of the liquid, and the temperature of the liquid drops. The gaseous refrigerant is transported from the heat exchanger 15 to the compressor 11 through the first pipeline 161, and the compressor 11 is used to compress the gaseous refrigerant. The heat exchanger 15 is arranged outside the liquid storage tank 12. The liquid in the liquid storage tank 12 first flows into the heat exchanger 15 through the liquid outlet 121 of the liquid storage tank for cooling and then flows into the brace A. The liquid in the brace A can flow into the heat exchanger 15 again for cooling, or the liquid in the brace A can flow back into the liquid storage tank 12, so that the brace A has a cold compress function, and the remaining liquid in the liquid storage tank 12 will no longer participate in the cycle, greatly improving the refrigeration efficiency and reducing the power consumption; Refer to Figure 14 As shown, the refrigeration speed: Under the condition that the ambient temperature is 25 - 28 °C, with a brace A with an area of 1 m 2 ², the surface temperature of the brace A reaches 5 °C within 5 minutes, the refrigeration electric power is 75 watts, and the refrigeration capacity reached is 250 watts. The refrigeration effect is good, the efficiency is high, it is stable, and the power is low. In addition, the system has a compact structure, is small and light, and is convenient to carry.

[0057] In one embodiment, refer to Figure 7 、 Figure 8 As shown, it further includes a three-way joint 17. The three-way joint includes a first interface 171, a second interface 172, and a third interface 173; The first interface 171 is connected to the liquid outlet 121 of the liquid storage tank; The second interface 172 is connected to the liquid inlet 153 of the heat exchanger; The third interface 173 is connected to the liquid outlet A2 of the brace.

[0058] In one embodiment, refer to Figure 7 、 Figure 8 As shown, the liquid outlet 121 of the liquid storage tank is connected to the first interface 171 through the fourth pipeline 164; The liquid inlet 153 of the heat exchanger is connected to the second interface 172 through the fifth pipeline 165; The liquid outlet 154 of the heat exchanger is connected to the liquid inlet A1 of the brace through the sixth pipeline 166; The liquid outlet A2 of the brace is connected to the third interface 173 through the seventh pipeline 167;

[0059] Wherein, a water pump 21 is provided on the fifth pipeline 165, and the water pump 21 is electrically connected to the control component; when the water pump 21 operates, the liquid in the liquid storage tank 12 flows through the heat exchanger 15 via the fourth pipeline 164 and the fifth pipeline 165 and then flows into the protective gear A via the sixth pipeline 166, and the liquid in the protective gear A flows through the heat exchanger 15 via the seventh pipeline 167 and the fifth pipeline 165 and then flows into the protective gear A again via the sixth pipeline 166; when the water pump 21 is closed, the liquid in the protective gear A flows into the liquid storage tank 12 via the seventh pipeline 167 and the fourth pipeline 164.

[0060] It should be noted that after the water pump 21 is closed, due to the relatively high pressure in the protective gear A, the liquid in the protective gear A will flow into the liquid storage tank 12 via the seventh pipeline 167 and the fourth pipeline 164.

[0061] In one embodiment, a liquid level detector 61 is further provided in the liquid storage tank 12, and the liquid level detector 61 is electrically connected to the control component.

[0062] In one embodiment, refer to Figure 7 、 Figure 12 As shown, a temperature sensor 62 is provided on the sixth pipeline 166, and the temperature sensor 62 is electrically connected to the control component.

[0063] In one embodiment, refer to Figure 8 、 Figure 13 As shown, a temperature sensor 62 is provided on the seventh pipeline 167, and the temperature sensor 62 is electrically connected to the control component.

[0064] It should be noted that the liquid level detector 61 is provided in the liquid storage tank 12 for detecting the height of the liquid level; the temperature sensor 62 is provided on the sixth pipeline 166 or the seventh pipeline 167 for detecting the temperature of the liquid entering or flowing out of the protective gear A, so as to control the temperature through the control component to achieve a suitable cold compress effect.

[0065] In one embodiment, the second pipeline 162 includes a throttling device, and the throttling device is provided between the heat exchanger 15 and the condenser 13.

[0066] It should be noted that the second pipeline 162 includes a second pipeline connection section extending out of the heat exchanger 15 to connect to the condenser 13 and a condenser section. The throttling device is arranged on the second pipeline connection section extending out of the heat exchanger 15 to connect to the condenser 13; the throttling device can be a capillary pipeline. After the second pipeline connection section extends out of the heat exchanger 15, there is a tendency for the pipeline diameter to decrease to form a capillary pipeline. Preferably, the diameter is reduced to 3-6 times the original pipeline diameter; the throttling device can also be a throttle valve or other throttling and pressure-reducing devices.

[0067] It is worth noting that the liquefied refrigerant after heat dissipation passes through a capillary pipeline with a smaller diameter. Due to the smaller cross-sectional area of the pipeline, the flow velocity becomes slower, thereby reducing its pressure and also accompanied by a decrease in temperature; at this time, the liquefied refrigerant with a higher pressure just output from the condenser 13 can be depressurized through the capillary pipeline.

[0068] In one embodiment, the condenser 13 includes a heat conduction pipe. One end of the heat conduction pipe extends out of the condenser 13 and is connected to the throttling device, and the other end of the heat conduction pipe extends out of the condenser 13 and is connected to the compressor 11.

[0069] It should be noted that the heat conduction pipe is a copper pipe, and the copper pipe is in a "U" shape and is arranged along the inner wall of the condenser 13. The high-temperature and high-pressure gaseous refrigerant enters the condenser section. The pipeline of the condenser section is provided with a copper pipe, which absorbs the heat of the gaseous refrigerant and gradually dissipates it into the surrounding environment; at the same time, the working surface of the fan 14 faces the position of the copper pipe in the condenser 13, further enabling the refrigerant to dissipate heat and liquefy. The liquefied refrigerant after heat dissipation through the copper pipe and the fan 14 enters the capillary pipeline for pressure reduction, and the liquefied refrigerant is transported to the heat exchanger 15 through the second pipeline 162.

[0070] In one embodiment, it further includes an air pump 22, a solenoid valve 23, and an air pipe 168. The air pump 22 is connected to the brace A through the air pipe 168, and the solenoid valve 23 is arranged on the air pipe 168; both the air pump 22 and the solenoid valve 23 are electrically connected to the control component; the brace A is inflated through the air pump 22, and the brace A deflates through the solenoid valve 23.

[0080] The problem to be solved in this embodiment lies in the technical problems of insufficient cooling effect and low efficiency of the refrigeration mechanism.

[0081] According to a portable cold therapy device M with optional compression therapy provided by the present utility model, the beneficial effects are as follows: First, the refrigeration mechanism is provided with a compressor 11, a condenser 13, a fan 14 and a heat exchanger 15. The high-temperature and high-pressure gaseous refrigerant is transported from the compressor 11 to the condenser 13 through the third pipeline 163. At this time, the high-temperature and high-pressure gaseous refrigerant has a relatively high temperature. The fan 14 is used to dissipate heat from the gaseous refrigerant in the condenser 13, and the gaseous refrigerant releases heat and liquefies; the liquid refrigerant is transported from the condenser 13 to the heat exchanger 15 through the second pipeline 162. The liquid refrigerant exchanges heat with the liquid in the heat exchanger 15, vaporizes after absorbing the heat of the liquid, and the temperature of the liquid drops; the gaseous refrigerant is transported from the heat exchanger 15 to the compressor 11 through the first pipeline 161, and the compressor 11 is used to compress the gaseous refrigerant; the heat exchanger 15 is arranged outside the liquid storage tank 12. The liquid in the liquid storage tank 12 first flows into the heat exchanger 15 for cooling through the liquid storage tank liquid outlet 121 and then flows into the brace A. The liquid in the brace A can flow into the heat exchanger 15 again for cooling, or the liquid in the brace A can flow back into the liquid storage tank 12, so that the brace A has a cold compress function, and the remaining liquid in the liquid storage tank 12 will no longer participate in the cycle, greatly improving the refrigeration efficiency and reducing the power consumption; refer to Figure 14 As shown in the figure, the refrigeration speed: under the condition that the ambient temperature is 25 - 28 °C, with a brace A with an area of 1 m 2 The surface temperature of the brace A reaches 5 °C within 5 minutes, the refrigeration electric power is 75 watts, and the refrigeration capacity reached is 250 watts. The refrigeration effect is good, the efficiency is high, it is stable, and the power is low. Second, an air pump 22 and an electromagnetic valve 23 are provided. By inflating, the brace A can be expanded to fit the treatment site more closely, so as to improve the treatment effect of the cold therapy liquid, and through the combination of inflation / deflation, the brace A can have medical effects such as massage. The portable cold therapy device M with optional compression therapy of the present utility model has a compact structure, is small and light, and is convenient to carry; it can perform cold compress and / or massage, has a wide range of uses, and improves the user experience.
