[0048] Figure 1 This diagram illustrates the structure of the multifunctional nursing device provided in an embodiment of the present invention. Figure 2 This diagram shows a partial structural schematic of the multifunctional nursing device provided in an embodiment of the present invention; Figure 3 Show Figure 2 A magnified view of a section marked A in the middle; Figure 4 An exploded view of part of the structure of the multifunctional nursing device provided in an embodiment of this utility model is shown. (Refer to...) Figures 1-4 This embodiment provides a multifunctional care device. This multifunctional care device can be a blanket structure, a sleeping bag structure, or other structure suitable for wrapping or partially wrapping the shoulders, waist, neck, knees, feet, ankles, and limbs, or can be worn by using Velcro or other adhesive attachments. In this embodiment, a sleeping bag structure is used as an example for description.
[0049] Specifically, the multifunctional nursing device includes a flexible nursing structure and a liquid supply control housing 400. The flexible nursing structure includes a flexible layer body 100, a light source layer 200, and a liquid-permeable layer 300. The light source layer 200 is disposed on the flexible layer body 100 and configured to emit light. Through the light source layer 200, light for physiotherapy is emitted to meet the user's phototherapy needs. The liquid-permeable layer 300 is stacked on the side of the light source layer 200 opposite to the flexible layer body 100 and is configured to allow the flow of cryotherapy liquid. The side of the liquid-permeable layer 300 opposite to the light source layer 200 forms a contact surface, which is configured to contact the human body. The light emitted by the light source layer 200 can pass through the liquid-permeable layer 300 to irradiate the human body. Through the liquid-permeable layer 300, the coldness of the cryotherapy liquid can be used to cool the human body. By combining the aforementioned fluid-permeable layer 300 and light source layer 200, the functions of cryotherapy and phototherapy can be integrated, enabling this multifunctional nursing device to simultaneously perform phototherapy and cryotherapy, simplifying the usage steps and improving the user experience.
[0050] It should be noted that the light used for physiotherapy can specifically be red light and infrared light, and its irradiance can be adjusted, specifically to 30mw / cm², 60mw / cm², 90mw / cm², 120mw / cm², or 150mw / cm², etc. Irradiance specifically represents the radiation power density per unit area; a higher value indicates greater light radiation intensity. In this embodiment, the light used for physiotherapy specifically includes two wavelengths, namely 630nm and 830nm. Users can select different wavelengths as needed.
[0051] It should be noted that the aforementioned cryotherapy liquid can be water, propylene glycol, or a coolant composed of water and propylene glycol in a certain proportion. In this embodiment, the cryotherapy liquid is specifically a mixture of water and propylene glycol, with the concentration of propylene glycol ranging from 20% to 60%. A concentration of 30% or 40% is considered the optimal concentration for cooling effect. The selection of the composition and proportion of the cryotherapy liquid is based on data obtained through numerous experiments, which are beneficial for improving cooling efficiency and cryotherapy effect.
[0052] It should be noted that the aforementioned cryotherapy fluid also includes additives such as corrosion inhibitors, pH adjusters, and bactericides. The specific composition and proportions of the coolant and various additives can be selected by technicians based on a balance of factors such as freezing point, viscosity, and cost, with the principle of ensuring the long-term stable operation of the entire system, effectively protecting the entire system from freezing damage and overheating, and extending the service life of the entire system.
[0053] More specifically, the light source layer 200 and the flexible layer body 100 are connected by a first adhesive portion arranged circumferentially. This first adhesive portion can be formed by hot pressing and / or gluing. The light source layer 200 and the liquid-permeable layer 300 are connected by a second adhesive portion arranged circumferentially. This second adhesive portion can also be formed by hot pressing and / or gluing.
[0054] Preferably, an edge-wrapping layer is attached to the periphery of the flexible layer body 100 by means of sewing, hot pressing, or adhesive bonding. This edge-wrapping layer folds over and wraps around the light source layer 200 and the liquid-permeable layer 300, and is attached to the upper side of the periphery of the light source layer 200. The aforementioned edge-wrapping layer can further improve the structural integrity of the flexible layer body 100, the light source layer 200, and the liquid-permeable layer 300.
[0055] More specifically, the light source layer 200 includes a plurality of light sources 211, which are staggered to avoid the flow channel 310 and are evenly spaced in both the width and length directions of the flexible layer body 100. The area of the liquid-permeable layer 300 corresponding to the light source 211 is a light-transmitting area 320, which is not connected to the flow channel 310. In this embodiment, a bonding and sealing area 350 can be formed between the light-transmitting area 320 and the flow channel 310 using hot pressing and / or adhesive bonding, and the upper and lower layers of the liquid-permeable layer 300 are connected to each other at the bonding and sealing area 350.
[0056] Alternatively, in one embodiment, the light-transmitting area 320 may have a light-transmitting hole corresponding to the light source 211, through which light from the light source 211 can illuminate the user's body.
[0057] Alternatively, in another embodiment, the light-transmitting area 320 may be made of a transparent material. The transparent material may be made of transparent flexible plastic or transparent silicone, with a light transmittance of at least 60%, and preferably at least 90%. The specific material is not limited in this embodiment.
[0058] Alternatively, in another embodiment, the liquid-permeable layer 300 may be made entirely of a transparent material.
[0059] It should be noted that in designs where no light-transmitting holes are provided in the light-transmitting area 320, gas can be filled into this area. Specifically, the gas can be nitrogen or similar substances, which can improve the comfort of the multifunctional care device's contact surface with the human body, enhancing the user experience. Simultaneously, it can also protect the light source 211, preventing pressure from the human body on the light source 211 and thus avoiding structural damage.
[0060] Since the multifunctional care device in this embodiment is a sleeping bag structure, it needs to include a padding layer and a thermal insulation layer. One side of the periphery of the padding layer and one side of the periphery of the thermal insulation layer are connected to each other to form a whole. The sides of the padding layer and the thermal insulation layer that are away from each other are respectively provided with Velcro or other fasteners. These fasteners can be pulled together to combine the padding layer and the thermal insulation layer into a sleeping bag shape with open ends, so as to wrap the user's body. In other embodiments, the fasteners can also be zippers or the like; the specific structure is not limited in this embodiment.
[0061] Specifically, refer to Figure 2 and Figure 3 In this embodiment, the liquid permeable layer 300 on the padding structure layer and the liquid permeable layer 300 on the insulation structure layer are connected by a flow hose 340, thereby realizing continuous circulation of the cryotherapy liquid.
[0062] Figure 5 Show Figure 4 A magnified view of the structure marked B in the middle section. (Refer to...) Figure 5 The liquid-permeable layer 300 of the padding structure layer has a liquid connector 330 at one end along its length. This liquid connector 330 connects to a first liquid-permeable tube (not shown), which can be connected to the outlet end of the cold therapy liquid source to guide the lower-temperature cold therapy liquid from the source into the flow channel 310. The liquid-permeable layer 300 on the insulating structure layer also has a liquid connector 330 at the same end along its length. This liquid connector 330 connects to a second liquid-permeable tube (not shown), which can be connected to the return end of the cold therapy liquid source to guide the higher-temperature cold therapy liquid from the flow channel 310 back to the cold therapy liquid source. Through this arrangement, circulation of the cold therapy liquid can be achieved between the cold therapy liquid source, the flow channel 310 of the padding structure layer, and the flow channel 310 of the insulating structure layer.
[0063] More specifically, in this embodiment, the exterior of the aforementioned flow hose 340 and the exterior of the connecting pipes between the liquid supply control box 400 and the liquid flow layer 300 are all wrapped with heat-insulating pipes (not shown in the figure), which can play a heat-insulating role and effectively reduce the generation of condensate.
[0064] Continue to refer to Figure 4The light source layer 200 includes a lamp panel 210 and a protective plate 220. The lamp panel 210 is disposed on the flexible layer body 100 and includes multiple light sources 211. The protective plate 220 is sandwiched between the lamp panel 210 and the liquid-permeable layer 300. The protective plate 220 has clearance holes 221 at the positions corresponding to the light sources 211 to allow the light from the light sources 211 to be emitted. The protective plate 220 can protect the body of the lamp panel 210 and further separate the lamp panel 210 and the liquid-permeable layer 300 to avoid interference between the two.
[0065] Preferably, in this embodiment, a waterproof film is also provided between the liquid-permeable layer 300 and the protective plate 220, which can provide further waterproof protection for the lamp plate 210 and prevent condensation or leaked water droplets from the liquid-permeable layer 300 from falling onto the lamp plate 210.
[0066] Figure 6 This diagram shows a partial structural representation of the liquid supply control box provided in an embodiment of the present invention. Figure 1 ; Figure 7 This diagram shows a partial structural representation of the liquid supply control box provided in an embodiment of the present invention. Figure 2 ; Figure 8 This diagram shows a partial structural representation of the liquid supply control box provided in an embodiment of the present invention. Figure 3 . Reference Figure 1 and Figures 6-8 The multifunctional nursing device also includes a fluid supply control box 400, which is configured to circulate cryotherapy fluid. In other words, in this embodiment, the cryotherapy fluid source is the fluid supply control box 400. Flow channels 310 within the fluid-permeable layer 300 are evenly distributed within the flexible layer body 100, allowing the cryotherapy fluid to circulate within the flow channels 310 and the fluid supply control box 400.
[0067] Specifically, in one embodiment, the liquid-permeable layer 300 is provided with a main flow channel connected to the liquid supply control box 400, and the flow channel 310 is connected to the main flow channel and covers the entire flexible layer body 100, which can provide users with uniform cold therapy.
[0068] More specifically, there are multiple flow channels 310, which are parallel to each other, spaced apart, and all parallel to the width direction of the liquid flow layer 300. In this embodiment, the main flow channel specifically includes two branches, both of which are parallel to the length direction of the liquid flow layer 300 and spaced apart from each other in the width direction of the liquid flow layer 300. Multiple flow channels 310 are connected between adjacent branches, and the outlet and inlet of the main flow channel are respectively connected to the liquid supply control box 400.
[0069] In addition, the flow channel 310 consists of multiple sets of flow channels, each set of flow channels including branch paths connected to the main flow channel and multiple horizontally parallel flow channels 310, as in this case... Figure 2 The 6 to 7 transverse channels 310 shown are set as a group. Grouping can reduce the total pressure in the first and second halves of the pipeline, making it less prone to leakage. Liquid can be introduced and discharged from multiple groups.
[0070] It should be noted that the liquid-permeable layer 300 on the aforementioned padding structure layer and the liquid-permeable layer 300 on the insulation structure layer are each provided with two branches. One branch on the padding structure layer has a liquid connector 330 at both ends. One liquid connector 330 is connected to the outlet end of the liquid supply control box 400 via a first liquid-permeable pipe, and the other liquid connector 330 is connected to a flow hose 340. Similarly, one branch on the insulation structure layer has a liquid connector 330 at both ends. One liquid connector 330 is connected to the flow hose 340, and the other liquid connector 330 is connected to the return end of the liquid supply control box 400 via a second liquid-permeable pipe. Through this arrangement, the cryotherapy liquid in the liquid supply control box 400 can circulate within the liquid-permeable layers 300 on both the padding structure layer and the insulation structure layer.
[0071] Alternatively, in another embodiment, the flow channel 310 is spirally arranged within the entire flexible layer body 100, and the outlet and inlet of the flow channel 310 are respectively connected to the outlet end and return end of the liquid supply control box 400 through corresponding liquid connectors 330.
[0072] Alternatively, in another embodiment, the flow channel 310 can also be arranged in a serpentine pattern throughout the entire flexible layer body 100, and the liquid outlet and liquid inlet of the flow channel 310 are respectively connected to the liquid outlet end and liquid return end of the liquid supply control box 400 through corresponding liquid connectors 330.
[0073] In other embodiments, the multifunctional care device can also be in the form of a non-sleeping bag. In this case, only a padded structural layer is needed to wrap around the user's body parts such as the waist, shoulders, or ankles. Then, only a flow channel 310 needs to be provided in the padded structural layer, without the need for a flow hose 340 or similar structures. Furthermore, only liquid connectors 330 need to be provided at both ends along the length of the padded structural layer to connect to the outlet and return ends of the liquid supply control box 400.
[0074] Reference Figures 6-8The liquid supply control housing 400 includes a housing 480, a liquid tank 410, and a first circulation pump 420. Both the liquid tank 410 and the first circulation pump 420 are integrated within the housing 480. The liquid tank 410 is configured to contain cryotherapy liquid, and the first circulation pump 420 is connected between the liquid tank 410 and the flow channel 310, configured to circulate the cryotherapy liquid between the liquid tank 410 and the flow channel 310.
[0075] Continue to refer to Figures 6-8 The liquid supply control enclosure 400 also includes a cooling system assembly and a second circulation pump 430. The cooling system assembly and the second circulation pump 430 are also integrated into the enclosure 480. The second circulation pump 430 is connected between the cooling system assembly and the liquid tank 410, and it drives the cryotherapy liquid to circulate between the cooling system assembly and the liquid tank 410, i.e., to perform an internal circulation process. The cooling system assembly is configured to cool the cryotherapy liquid. Through the aforementioned second circulation pump 430 and cooling system assembly, a pre-cooling process is performed before the cryotherapy liquid flows to the flow channel 310 through the external circulation process, thereby reducing the temperature of the cryotherapy liquid, improving the efficiency and effect of cooling, and thus ensuring the cryotherapy effect.
[0076] Specifically, a controller 440 is also provided inside the liquid supply control box 400. The lamp panel 210 and the first circulation pump 420 are respectively communicatively connected to the controller 440. The controller 440 can control the light irradiance and wavelength of the light source layer 200, and can also control the start and stop of the circulation of the cryotherapy liquid in the liquid flow layer 300. In this embodiment, the controller 440 may be a microcontroller or the like, and its specific structure and control principle will not be described in detail here.
[0077] To be more specific, continue to refer to Figure 1 The liquid supply control box 400 also includes a knob 450 and a human-machine interface screen 460. The knob 450 and the human-machine interface screen 460 are respectively located on the box 480 for user operation and are both communicatively connected to the controller 440, enabling the user to issue commands to the controller 440, which then controls the operation of related components. In phototherapy mode, the human-machine interface screen 460 can display data such as the current light irradiance, the set phototherapy duration, and the remaining phototherapy duration. In cryotherapy mode, the human-machine interface screen 460 can display data such as the current temperature of the cryotherapy liquid, the set cryotherapy duration, and the remaining cryotherapy duration. A detailed schematic diagram of the display interface of the aforementioned human-machine interface screen 460 is shown below. Figure 9 As shown.
[0078] In this embodiment, the cooling system components specifically include a compressor 471, a plate heat exchanger 472, a condenser 474, and a fan 473. The compressor 471 compresses and delivers refrigerant. It first draws in low-temperature, low-pressure refrigerant gas, compresses it, and converts it into high-temperature, high-pressure refrigerant gas. Then, the high-temperature, high-pressure refrigerant gas is delivered to the condenser 474. The condenser 474 utilizes the airflow from the fan 473 for heat exchange, carrying away the heat from the high-temperature, high-pressure refrigerant gas from the compressor 471, cooling and condensing the gas to form a refrigerant liquid. The refrigerant liquid then enters a throttling tube for further depressurization and cooling, forming a low-temperature refrigerant liquid, which is then delivered to the plate heat exchanger 472. In the plate heat exchanger 472, the refrigerant liquid from the liquid tank 410 is cooled through heat exchange.
[0079] More specifically, during the external circulation process, the cryotherapy liquid pumped by the first circulation pump 420 also needs to pass through the plate heat exchanger 472 to exchange heat with the refrigerant and cool down before being transported to the circulation channel 310.
[0080] More specifically, the inlet and outlet of the first circulation pump 420 are respectively equipped with solenoid valves 421. The liquid tank 410 is provided with an upper liquid port 411 (i.e., the return end of the liquid supply control box 400) and a lower liquid port 412 (i.e., the outlet end of the liquid supply control box 400). The upper liquid port 411 is set at a higher height than the lower liquid port 412. The upper liquid port 411 is connected to the flow channel 310 through a first connecting pipe (not shown); the lower liquid port 412 is connected to one solenoid valve 421, and the other solenoid valve 421 is connected to the flow channel 310 through a second connecting pipe (not shown). It should also be noted that the highest liquid level of the cryotherapy liquid in the liquid tank 410 is lower than the setting height of the upper liquid port 411.
[0081] When the first circulation pump 420 delivers the cryotherapy liquid from the liquid tank 410 to the flow channel 310, both solenoid valves 421 are in their first state (i.e., the liquid outlet state where the cryotherapy liquid is directed from the liquid tank 410 to the flow channel 310). At this time, the cryotherapy liquid in the liquid tank 410 flows out through the lower outlet 412 and enters the first circulation pump 420, which then pumps it to the flow channel 310. During the external circulation process, the cryotherapy liquid returning to the liquid tank 410 from the flow channel 310 enters the liquid tank 410 through the upper outlet 411.
[0082] When the first circulating pump 420 is used to recover the cryotherapy liquid in the flow channel 310, the two solenoid valves 421 are switched to the second state, that is, the return liquid functional state in which the cryotherapy liquid flows back from the flow channel 310 to the liquid tank 410. At this time, the air in the liquid tank 410 flows into the flow channel 310 through the upper liquid port 411, and the cryotherapy liquid in the flow channel 310 and the above-mentioned air are drawn by the first circulating pump 420 to flow back to the lower liquid port 412 and then recovered into the liquid tank 410. In this process, the air can purge the residual cryotherapy liquid in the flow channel 310, so as to improve the recovery effect of the cryotherapy liquid in the flow channel 310. A liquid level gauge is arranged in the liquid tank 410, and when the liquid level in the liquid tank 410 reaches the liquid level gauge, the liquid level gauge can send a liquid recovery completion signal to the controller 440.
[0083] It should be noted that the above-mentioned solenoid valve 421 is communicatively connected to the controller 440, and the controller 440 can control the switching of the solenoid valve 421 between the first state and the second state. That is to say, the above-mentioned controller 440 can control the recovery of the cryotherapy liquid, which facilitates the recovery of the cryotherapy liquid in the flow channel 310 after the cryotherapy is completed.
[0084] More specifically, the liquid tank 410 is provided with a temperature sensor 413, which is communicatively connected to the controller 440 and can detect the temperature of the cryotherapy liquid in the liquid tank 410. The temperature of the cryotherapy liquid is adjustable, and the adjustable temperatures include 5°C, 10°C and 15°C. The controller 440 can adjust the rotation speed of the compressor according to the temperature set by the user and the temperature detected by the temperature sensor 413, thereby realizing the adjustment of the temperature of the cryotherapy liquid.
[0085] Preferably, a water level sensor is arranged in the liquid tank 410. The water level sensor is used to detect the water level in the liquid tank 410. If the detected water level is too low, it indicates that there is not enough cryotherapy liquid for circulation at this time, and the inner circulation process or the outer circulation process is controlled to stop, so as to protect the plate heat exchanger 472 from being damaged due to overcooling.
[0086] Preferably, a flow sensor is arranged in the pipeline between the liquid tank 410 and the flow channel 310, and the flow sensor is configured to detect the flow of the cryotherapy liquid during the external circulation process. If the detected flow of the cryotherapy liquid is too low, it indicates that there is a blockage in the flow channel 310 or the pipeline in the liquid supply control box 400, and the controller 440 controls an alarm (not shown in the figures) to give an alarm, prompting the operator to perform maintenance and inspection.
[0087] Preferably, a pressure sensor is installed at the outlet and / or inlet of the flow channel 310. This pressure sensor is communicatively connected to the controller 440 and is specifically configured to detect liquid pressure. If the pressure sensor detects that the liquid pressure has reached an alarm value, it indicates that there is a blockage in the flow channel 310 or the pipeline within the liquid supply control box 400. The controller 440 then activates an alarm (not shown) to alert the operator for maintenance and inspection.
[0088] The liquid supply control housing 400 provided in this embodiment has a length of 546 mm, a width of 440 mm, and a height of 423 mm, and weighs approximately 14.8 kg. The liquid supply control housing 400 has a high degree of integration and a small size, making it easy to carry. The sleeping bag structure provided in this embodiment has a length of 2045 mm and a width of 1920 mm, and weighs approximately 12 kg. The dimensions of the sleeping bag structure are suitable for lying down and can be rolled up for storage, reducing its size and making it easy to carry.
[0089] The liquid supply control box 400 is equipped with a box body 480, a telescopic rod and multiple wheels. The rod is retracted or extended from one side of the box body 480, which facilitates the transfer and transportation of the liquid supply control box 400 by the user. During transportation, the light-cooled carrier, i.e. the flexible care structure, which is in a rolled-up storage state, is placed on the top of the box body 480 with a small volume. The top is set as a relatively flat plane, so that the flexible care structure is placed stably during transportation.
[0090] The multifunctional nursing device provided in this embodiment specifically includes three working modes, such as... Figure 10 As shown, these are the phototherapy mode, cryotherapy mode, and smart mode. It should be noted that in smart mode, the controller 440 can automatically control the device to first enter cryotherapy mode and then phototherapy mode. Through these steps, the device can provide the user with the most effective therapeutic effect.
[0091] The operation process of the above-mentioned multifunctional nursing device is as follows:
[0092] First, connect the pipelines between the liquid supply control box 400 and the liquid flow layer 300, as well as the wiring between the liquid supply control box 400 and the light source layer 200. Then, turn on the power switch on the liquid supply control box 400. At this time, the liquid supply control box 400 is in the power-on state, the human-machine interface screen 460 lights up, and the white ambient lights around the liquid supply control box 400 illuminate.
[0093] It should be noted that if the equipment malfunctions at this time, a yellow ambient light will illuminate, and a fault code will be displayed. Furthermore, if an emergency occurs and the user presses the emergency stop button on the housing 480 of the liquid supply control box 400, the power will be immediately cut off. After the power is cut off, the emergency stop button will re-emerge for subsequent power restoration.
[0094] After the liquid supply control unit 400 starts normally, the duration, light irradiance, and cryotherapy temperature of the current mode can be adjusted using knob 450. For example, in phototherapy mode, the duration can be set to 5 minutes, 15 minutes, 20 minutes, 25 minutes, or 30 minutes, and the light irradiance can be set to 30mw / cm², 60mw / cm², 90mw / cm², 120mw / cm², or 150mw / cm². Similarly, in cryotherapy mode, the duration can be set to 5 minutes, 10 minutes, or 15 minutes, and the cryotherapy temperature can be set to 5 degrees Celsius, 10 degrees Celsius, or 15 degrees Celsius. Furthermore, in intelligent mode, the total duration of phototherapy and cryotherapy can be set to 15 minutes, 20 minutes, 25 minutes, 30 minutes, or 35 minutes, or the durations of phototherapy and cryotherapy can be set separately. In intelligent mode, the light irradiance can be set to 30mw / cm², 60mw / cm², 90mw / cm², 120mw / cm², or 150mw / cm², etc.; the temperature of cryotherapy can also be set to 5 degrees Celsius, 10 degrees Celsius, and 15 degrees Celsius, etc.
[0095] Preferably, to enhance the user experience, in smart mode, the duration and temperature of the cryotherapy process can be set in a correlated manner, specifically a 5-minute cryotherapy session at 5 degrees Celsius and a 10-minute cryotherapy session at 15 degrees Celsius. After the cryotherapy is completed, the remaining time is used for phototherapy.
[0096] Preferably, pressing the knob 450 allows selection of phototherapy mode, cryotherapy mode, and smart mode.
[0097] In light therapy mode, after setting all the data, press and hold the knob at 450 for three seconds to start the light therapy. At this time, the purple ambient light will light up, and the remaining time will be displayed using a countdown.
[0098] Specifically, after the phototherapy countdown ends, the ambient lights around the liquid supply control unit 400 flash three times and then turn white. If the user wishes to continue using the device, they can use knob 450 to reselect the mode. If the user wishes to end use at this point, they can turn off the power switch on the liquid supply control unit 400.
[0099] More specifically, if you need to stop during the light therapy process, you can press and hold the knob at 450 for three seconds to fast forward to the mode after the light therapy countdown ends.
[0100] In cryotherapy mode, after setting all the data, if phototherapy mode is also in progress, a short press of knob 450 will turn off light source 211. If phototherapy mode is not in progress, a long press of knob 450 for three seconds will initiate the pre-cooling process of the cryotherapy liquid. During this pre-cooling process, the human-machine interface 460 will display the pre-cooling progress percentage, and the liquid supply control unit 400 will display a slow-flashing purple ambient light. Once the cryotherapy liquid has reached the required pre-cooling temperature, the pre-cooling process ends, and the human-machine interface 460 will display a constantly lit purple ambient light.
[0101] Specifically, after the pre-cooling process of the cryotherapy liquid is completed, press the water injection button on the housing 480 of the liquid supply control box 400 briefly to start the external circulation process. At this time, the cryotherapy liquid in the liquid tank 410 can flow into the circulation channel 310 to perform cryotherapy on the human body. At this time, the human-machine interaction screen 460 can display the remaining time by using a countdown method.
[0102] More specifically, after the cold therapy countdown ends, the ambient light around the liquid supply control unit 400 flashes three times and then turns white. Simultaneously, the liquid supply control unit 400 automatically collects water, reclaiming the water from the circulation channel 310. If the user wishes to continue using the device, they can use the knob 450 to reselect the mode. If the user wishes to end use, they can turn off the power switch on the liquid supply control unit 400.
[0103] More specifically, if you need to stop the cryotherapy process, you can press and hold the knob at 450 for three seconds to fast forward to the mode after the cryotherapy countdown has ended.
[0104] The multifunctional nursing device provided in this embodiment, in actual use testing, specifically includes the following process:
[0105] At a room temperature of 30°C, an antifreeze concentration of 30%, and a noise level of approximately 60dB, the liquid supply control unit 400 first performs a pre-cooling process. The cryotherapy liquid can be cooled to -8°C in 30 minutes, to -10°C in 35 minutes, and to -12°C in approximately 40-45 minutes. The cooling then slows down (the antifreeze concentration needs to be increased to continue cooling). At this point, the cryotherapy liquid is filled into the liquid circulation layer 300.
[0106] After 3 minutes, the temperature of the liquid layer 300 dropped from 30 degrees Celsius to 4 degrees Celsius, and then remained relatively stable, slowly decreasing to 2.5 degrees Celsius.
[0107] After 55 minutes, the test subject entered the sleeping bag structure. After 15 minutes, the temperature of the sleeping bag structure slowly rose to 7°C and remained stable.
[0108] After the water collection function is activated, the liquid layer 300 is completely collected within 3 minutes, leaving only a small amount of water residue in the water channel.
[0109] Then, the sleeping bag is rolled up from one end along its length to the other. After being rolled up, it can be placed directly on top of the liquid supply control box 400, taking up very little space.
