Description

Technical Field

[0001] This application relates to the field of sports injury rehabilitation technology, and in particular to a hot and cold compress device that can simultaneously increase and decrease pressure. Background Technology

[0002] As one of the joints in the human body that bears the most weight and is most frequently used, the knee joint is prone to sprains, ligament strains, or meniscus injuries during sports such as ball games and running. When a sports injury occurs in the knee joint, timely application of alternating hot and cold compresses to the injured area can have an effective rehabilitation effect. For example, cold compresses can promote local vasoconstriction and reduce the release of inflammatory factors; hot compresses can dilate blood vessels, promote blood flow, and relieve muscle soreness.

[0003] However, traditional hot and cold compress devices typically use cold and hot compress bags to apply heat and cold compresses to the injured knee joint, providing only a single function of cold or hot compress. Furthermore, they cannot adjust the temperature of the cold or hot compresses, and they cannot perform simultaneous pressure-relieving massage during the hot and cold compresses. They lack the synergistic effect of alternating hot and cold compresses and simultaneous pressure-relieving massage, resulting in poor rehabilitation effects for users' sports injury sites and failing to meet users' rehabilitation needs for sports injury sites.

[0043] The following specific embodiments illustrate the implementation of this application. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification.

[0044] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.

[0045] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, article, or apparatus that comprises a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, article, or apparatus.

[0047] In the embodiments of this application, the words "exemplary" or "for example" are used to indicate that they are examples, illustrations, or descriptions. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design; rather, the use of the words "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0048] Traditional hot and cold compress devices typically use cold and hot compress bags to apply heat and cold to the injured knee joint, providing only a single function of cold or hot compress. Furthermore, they cannot adjust the temperature of the cold or hot compress and cannot perform simultaneous pressure-relieving massage during the hot and cold compress. They lack the synergistic effect of alternating hot and cold compresses and simultaneous pressure-relieving massage, resulting in poor rehabilitation effects for users' sports injury sites and failing to meet users' rehabilitation needs for sports injury sites.

[0049] To address the aforementioned technical problems, this application provides, in one aspect, a hot and cold compress device capable of simultaneously increasing and decreasing pressure. For example... Figure 1 , Figure 4 and Figure 6 As shown, in some embodiments, the hot and cold compress device may include an adhesive body 11, at least one hot and cold compress component 13, at least one airbag component 14, and a controller 15. The adhesive body 11 is used to adhere to the area of ​​the human body to be treated; the adhesive body 11 has a hot and cold compress area corresponding to the area of ​​the human body to be treated; the hot and cold compress component 13 is disposed in the hot and cold compress area and is used to adjust the temperature of the hot and cold compress area; the airbag component 14 is disposed in the adhesive body 11; the airbag component 14 includes a first airbag 141 disposed in the hot and cold compress area, the first airbag 141 being used to adjust the pressure of the hot and cold compress area; the controller 15 is disposed in the adhesive body 11; the controller 15 is electrically connected to the hot and cold compress component 13 and is used to control the hot and cold compress component 13 to alternately perform cold and hot compresses; the controller 15 is electrically connected to the airbag component 14 and is used to control the inflation and deflation of the first airbag 141 when the hot and cold compress component 13 alternately performs cold and hot compresses.

[0050] For example, the adhesive body 11 can be made of a flexible material; for instance, it can be made of a silicon-based material, which can form a good fit with the area of ​​the body to be treated. The hot and cold compress component 13 can be connected to the adhesive body 11 by heat pressing or bonding. The controller 15 can be connected to the adhesive body 11 by heat pressing or bonding. It should be noted that, in this embodiment, the hot and cold compress component 13 and the controller 15 can also be installed on the adhesive body 11 by other connection methods, as long as the hot and cold compress component 13 and the controller 15 can be stably installed on the adhesive body 11, and no limitation is made here. The controller 15 can be electrically connected to a terminal mobile device such as a mobile phone or tablet computer. For example, the controller 15 can be controlled in real time through a mobile phone APP, which can be applied to different application scenarios.

[0051] For example, the areas of the body to be treated can be sports injury sites requiring rehabilitation, such as the knee joint, thigh, calf, and arm. For instance, as... Figure 7As shown, when the area to be treated is the knee joint, the device can effectively fit the knee joint and provide rehabilitation for that area; for example, as Figure 8 As shown, when the area to be treated is the thigh, the device can effectively fit the thigh and provide rehabilitation for that area.

[0052] By providing hot and cold compress zones on the patch 11 corresponding to the areas of the body to be treated, and by providing at least one hot and cold compress component 13 in each hot and cold compress zone for adjusting the temperature of the zone, the temperature of the hot and cold compress zone can be adjusted by the controller 15 when applying hot and cold compresses to the sports injury area to ensure the hot and cold compress effect. At the same time, at least one airbag component 14 is provided on the patch 11, and a first airbag 141 for adjusting the pressure of the hot and cold compress zone is provided in the hot and cold compress zone. The first airbag 141 can be inflated and deflated by the controller 15. Therefore, while applying hot and cold compresses to the sports injury area, the pressure can be adjusted simultaneously for pressure increase and decrease massage, which can effectively improve the rehabilitation effect of the user's sports injury area.

[0053] When using the device, users can select either a cold compress, a hot compress, or an alternating hot and cold compress mode. For example, when selecting the cold compress mode, the controller 15 can control the hot and cold compress component 13 to perform cooling, maintaining the temperature of the hot and cold compress area within a first set temperature range, which can be between 10 and 16°C. Simultaneously, the controller 15 can control the inflation and deflation of the first airbag 141, allowing the hot and cold compress area to provide pressure relief massage to the affected area. During this process, the cooperation between the controller 15 and the hot and cold compress component 13 maintains the temperature of the hot and cold compress area within a suitable cold compress temperature range, while simultaneously inflating and deflating the first airbag 141 to maintain a set pressure, which can be between 0 and 150 mmHg. This allows for simultaneous pressure relief massage to the injured area, effectively promoting local vasoconstriction and reducing the release of inflammatory factors, thus significantly improving the cold compress effect on the injured area.

[0054] For example, when the hot compress mode is selected, the controller 15 controls the hot and cold compress component 13 to generate heat, keeping the temperature of the hot and cold compress area in a second set temperature range, which can be between 38 and 42°C. Simultaneously, the controller 15 controls the inflation and deflation of the first airbag 141, allowing the hot and cold compress area to provide pressure relief massage to the area to be treated. During this process, the cooperation between the controller 15 and the hot and cold compress component 13 can keep the temperature of the hot and cold compress area within a suitable hot compress temperature range, and the simultaneous inflation and deflation of the first airbag 141 can provide synchronous pressure relief massage to the injured area, which can dilate blood vessels and promote blood flow, relieve muscle soreness, and effectively improve the hot compress effect on the injured area.

[0055] At the same time, alternating between cold and hot compresses, applying hot and cold compresses to the affected area while simultaneously performing pressure-relieving massage, can improve the rehabilitation effect on sports injuries.

[0056] For example, such as Figure 1 As shown, the synchronously decompression and cooling device can include an elastic bandage 12, and the fitting body 11 is provided with a bandage loop 16 for the elastic bandage 12 to pass through. The fitting body 11 is attached to the part of the body to be treated by the elastic bandage 12. Based on this structure, the elastic bandage 12 can be used to tightly attach the fitting body 11 to the part of the body to be treated, for example, the fitting body 11 can be tightly attached to the knee joint, or the fitting body 11 can be tightly attached to other sports injury parts of the body that need rehabilitation. At the same time, since the first airbag 141 needs to be deflated during the process of cold compress, hot compress, or alternating cold and hot compress, the elastic bandage 12 can be used to squeeze the first airbag 141, thereby deflating the first airbag 141 and reducing the pressure in the cold and hot compress area.

[0057] like Figure 2 As shown, in some embodiments, the adhesive body 11 may include a decorative layer 111, a structural reinforcement layer 112, and a skin-adhesive layer 113. The structural reinforcement layer 112 is disposed between the decorative layer 111 and the skin-adhesive layer 113, and the decorative layer 111 and the structural reinforcement layer 112 can be connected by heat pressing. The structural reinforcement layer 112 and the skin-adhesive layer 113 are bonded together, and a gap is provided between the structural reinforcement layer 112 and the skin-adhesive layer 113. The hot and cold compress area is located in the skin-adhesive layer 113. By designing the adhesive body 11 as a multi-layer structure and providing a structural reinforcement layer 112 between the decorative layer 111 and the skin-adhesive layer 113, the overall structural stability can be improved. Moreover, a gap space is reserved between the structural reinforcement layer 112 and the skin-adhesive layer 113. Specifically, this gap space is located in the hot and cold compress area. Based on this structure, by increasing or decreasing the volume of the gap space, the hot and cold compress area can produce a massage effect of pressure or decompression.

[0058] For example, such as Figure 3 As shown, the skin-adhesive layer 113 has several annularly spaced through holes 1131 at positions corresponding to the hot and cold compress areas. The structural reinforcement layer 112 also has several openings corresponding to the through holes 1131. The through holes 1131 and openings can be used to install the hot and cold compress component 13. The adhesive body 11 also includes an edge binding fabric 114, which can be sewn to the outer edges of the decorative layer 111, the structural reinforcement layer 112, and the skin-adhesive layer 113, thereby improving the overall aesthetic effect of the adhesive body 11.

[0059] like Figure 3As shown, in some embodiments, the airbag assembly 14 may further include a first air pump 142 and a first solenoid valve 143. The first air pump 142 and the first solenoid valve 143 are electrically connected via a first three-way valve 144, which is electrically connected to the controller 15. The first solenoid valve 143 may be located in the air passage of the first airbag 141 to control the opening or closing of the air passage. Since the first air pump 142 and the first solenoid valve 143 are electrically connected via the first three-way valve 144, which is electrically connected to the controller 15, and the first solenoid valve 143 is located in the air passage of the first airbag 141, this structure can effectively control the opening and closing of the air passage of the first airbag 141 and simplify the electrical connection structure. It is understood that the first three-way valve 144 in the embodiments of this application may be an air passage connector.

[0060] It should be noted that in this embodiment, the first airbag 141 may have only one air passage, which can serve as both the inlet and outlet passage of the first airbag 141. For example, when inflation is required, the first control valve 143 controls the opening of the air passage and simultaneously starts the first air pump 142, allowing air to fill the first airbag 141 through the air passage. Similarly, when deflation is required, the first control valve 143 controls the opening of the air passage and simultaneously shuts off the first air pump 142, allowing the first airbag 141 to deflate through the air passage under the elastic compression of the elastic strap 12. Based on this structure, the structure of the airbag assembly 14 can be simplified, making the airbag assembly 14 more compact, further reducing the product size and improving the product's portability.

[0061] For example, such as Figure 3 As shown, the first airbag 141 can be disposed on the structural reinforcement layer 112. When the first airbag 141 is inflated, it applies pressure to the hot and cold compress area. Specifically, the structural reinforcement layer 112 is provided with the aforementioned hot and cold compress area, and the first airbag 141 is disposed in the hot and cold compress area. When the first airbag 141 is inflated, it can apply pressure to the hot and cold compress area, which can increase the massage effect on the injured part of the body and further improve the rehabilitation effect of the part.

[0062] For example, such as Figure 3 As shown, the airbag assembly 14 may also include a first fixing member 145 and a first housing 146. A structural reinforcement layer 112 is disposed between the first fixing member 145 and the first housing 146. Furthermore, by installing the first air pump 142, the first solenoid valve 143, and the first three-way valve 144 in the first housing 146, the installation stability and compactness of the first air pump 142, the first solenoid valve 143, and the first three-way valve 144 can be improved.

[0063] like Figure 3As shown, in some embodiments, the synchronously pressurized and depressurized hot and cold compress device may further include a second airbag assembly 17 disposed on the fitting body 11. The second airbag assembly 17 is spaced apart from the airbag assembly 14, and the airbag assembly 14 and the second airbag 171 are disposed away from the hot and cold compress assembly 13. The second airbag assembly 17 includes a second airbag 171 disposed in the hot and cold compress area. The second airbag 171 is symmetrically disposed with the first airbag 141, and the second airbag 171 is used to regulate the temperature of the hot and cold compress area. The controller 15 is electrically connected to the second airbag assembly 17 and is used to control the inflation and deflation of the second airbag 171 when the hot and cold compress assembly 13 alternately applies cold and hot compresses. Specifically, the second airbag assembly 17 and the airbag assembly 14 are independently and spaced apart on the structural reinforcement layer 112, and the second airbag 171 and the first airbag 141 are symmetrically disposed on the structural reinforcement layer 112.

[0064] Based on this structure, the first airbag 141 and the second airbag 171 can be ergonomically fitted, further improving the rehabilitation effect of sports injuries. For example, as Figure 7 As shown, when the synchronously pressure-relieving hot and cold compress device is applied to the knee joint, it can effectively fit the knee joint. Because the second airbag 171 and the first airbag 141 are symmetrically arranged, they can cover the knee joint area, allowing for simultaneous hot and cold compresses and pressure-relieving massage, effectively improving the rehabilitation effect for knee joint sports injuries; for example, as... Figure 8 As shown, when the synchronous pressure-reducing hot and cold compress device is applied to the thigh, it can effectively adhere to the thigh and simultaneously perform pressure-reducing massage on the injured area of ​​the thigh while applying alternating hot and cold compresses, effectively improving the rehabilitation effect on the injured area of ​​the thigh.

[0065] For example, such as Figure 3 As shown, the second airbag assembly 17 may further include a second air pump 172 and a second solenoid valve 173. The second air pump 172 and the second solenoid valve 173 are electrically connected via a second three-way valve 174, which is electrically connected to the controller 15. The second solenoid valve 173 can be located in the air passage of the second airbag 171 to control the opening or closing of the air passage. Since the second air pump 172 and the second solenoid valve 173 are electrically connected via the second three-way valve 174, and the second three-way valve 174 is electrically connected to the controller 15, and the second solenoid valve 173 is located in the air passage of the second airbag 171, the opening and closing of the air passage of the second airbag 171 can be effectively controlled, and the electrical connection structure can be simplified. It is understood that the second three-way valve 174 in this embodiment can be an air passage connector.

[0066] For example, such as Figure 3As shown, the second airbag assembly 17 may also include a second fixing member (not shown) and a second housing 175. A structural reinforcement layer 112 is disposed between the second fixing member and the second housing 175. Furthermore, by installing the second air pump 172, the second solenoid valve 173, and the second three-way valve 174 in the second housing 175, the installation stability and compactness of the second air pump 172, the second solenoid valve 173, and the second three-way valve 174 can be improved.

[0067] like Figures 1 to 4 As shown, in some embodiments, the hot and cold compress assembly 13 may include a thermally conductive silicone pad 131, a thermoelectric cooler 132, and a heat sink 133. The thermally conductive silicone pad 131 is disposed on the skin-adhesive layer 113 and can adhere to the area of ​​the body to be treated. The thermoelectric cooler 132 passes through the decorative layer 111 and the structural reinforcement layer 112. The thermally conductive silicone pad 131 is disposed on the side of the thermoelectric cooler 132 close to the skin-adhesive layer 113. The heat sink 133 passes through the decorative layer 111 and the structural reinforcement layer 112. The heat sink 133 is disposed on the side of the thermoelectric cooler 132 away from the thermally conductive silicone pad 131. Specifically, the thermally conductive silicone pad 131, the semiconductor cooling pad 132, and the heat sink 133 are all located in the aforementioned hot and cold compress area. The shape and size of the thermally conductive silicone pad 131 are adapted to the shape and size of the through hole 1131 of the skin layer 113. The thermally conductive silicone pad 131 can be connected to the through hole 1131 by an adhesive. Moreover, the side of the thermally conductive silicone pad 131 facing the part of the human body to be treated can be in the same plane as the plane of the skin layer 113.

[0068] Based on this structure, when the hot and cold compress area needs to be heated, the heat generated by the semiconductor cooling chip 132 can be transferred to the hot and cold compress area through the thermally conductive silicone sheet 131, so that the hot and cold compress area can produce a hot compress effect; when the hot and cold compress area needs to be cooled, the semiconductor cooling chip 132 can be cooled and the heat dissipation block 133 can dissipate heat, so that the hot and cold compress area can produce a cold compress effect.

[0069] For example, such as Figure 4 As shown, the hot and cold compress assembly 13 may include a fan 134, a base 135, and a pad 138. The fan 134 is installed on the side of the heat sink 133 away from the thermoelectric cooler 132, and the fan 134 is installed between the base 135 and the heat sink 133. The base 135 can fix the thermal conductive silicone pad 131, the thermoelectric cooler 132, the heat sink 133, and the fan 134.

[0070] For example, the hot and cold compress assembly 13 may further include a cylindrical third housing 136 and a cover 137, wherein the cylindrical third housing 136 can be snapped together with the base 135, the cover 137 is mounted on the third housing 136, and the cover 137 is provided with a vent communicating with the outside. A gasket 138 is installed between the thermoelectric cooling chip 132 and the skin-adhesive layer 113, which can protect the thermoelectric cooling chip 132.

[0071] like Figures 1 to 4 As shown, in some embodiments, the synchronously adjustable hot and cold compress device may further include a plurality of second hot and cold compress components 18 disposed in the hot and cold compress area for adjusting the temperature of the hot and cold compress area; the plurality of second hot and cold compress components 18 and hot and cold compress components 13 are arranged in a ring at intervals in the hot and cold compress area; the controller 15 is electrically connected to the second hot and cold compress components 18 for controlling the second hot and cold compress components 18 to alternately perform cold and hot compresses. It should be noted that in the embodiments of this application, the structure of the second hot and cold compress components 18 is the same as the structure of the hot and cold compress components 13, and will not be described again here. Based on this structure, by arranging the hot and cold compress components 13 and the second hot and cold compress components 18 in a ring at intervals in the hot and cold compress area, the ergonomic fit and hot and cold compress requirements can be met, and the rehabilitation effect of the hot and cold compress components 13 and the second hot and cold compress components 18 on the human body sports injury site by cold compress, hot compress, or alternating hot and cold compress can be improved.

[0072] For example, such as Figure 1 , Figure 3 and Figure 7 As shown, when the area to be treated is the knee joint, the synchronously pressure-increasing and pressure-reducing hot and cold compress device can effectively fit the knee joint. Since the hot and cold compress area is arranged in a ring shape and is provided with hot and cold compress component 13 and several second hot and cold compress components 18 at intervals, the hot and cold compress component 13 and several second hot and cold compress components 18 can cover the knee joint area. At the same time, since the second airbag 171 and the first airbag 141 are symmetrically arranged, the second airbag 171 and the first airbag 141 can cover the front area of ​​the knee joint and both sides of the knee. Therefore, while applying hot and cold compresses to the knee joint, pressure-increasing and pressure-reducing massage can be performed simultaneously, which is beneficial to improving the rehabilitation effect of knee joint sports injuries.

[0073] For example, the synchronously adjustable hot and cold compress device may further include a temperature sensor located in the hot and cold compress area. The temperature sensor is electrically connected to the controller 15 and is used to collect the temperature of the hot and cold compress area. Based on this structure, the temperature sensor can control the cold compress area to maintain a cold compress temperature between 10 and 16°C, and the temperature sensor can also control the cold compress area to maintain a hot compress temperature between 38 and 42°C. Furthermore, it can effectively control the temperature of alternating hot and cold compresses, thereby improving the rehabilitation effect on sports injury sites.

[0074] like Figure 5As shown, in some embodiments, the controller 15 may include a control chip 151, a battery 152, several control buttons 153, a fourth housing 154, and a fifth housing 155. The fourth housing 154 and the fifth housing 155 are connected by screws, and an inner cavity is provided between them. The control chip 151 and the battery 152 are installed in this inner cavity. The control buttons 153 are installed in the battery 152, with one end extending out of the fourth housing 154, facilitating manual pressing and selection of different operating modes. The control buttons 153 can be divided into a start button, a mode button, and a pressure button. For example, pressing the mode button once switches modes. During use, the user can select from cooling level 1, cooling level 2, heating level 1, and heating level 2 according to the temperature requirements of the hot and cold compress.

[0075] On the other hand, this application provides a control method for a synchronously increasing / decreasing hot / cold compressive therapy device based on the foregoing embodiments, the control method comprising:

[0076] The working mode can be selected by controlling button 153. The working modes can include cold compress, hot compress and alternating hot and cold compress.

[0077] When cold compress is selected, the controller 15 controls the hot and cold compress component 13 to perform cooling, so that the temperature of the hot and cold compress area is maintained in the first set temperature range; during the cold compress process, the controller 15 simultaneously controls the first airbag 141 to inflate, and keeps the first airbag 141 inflated for a set time, so that the hot and cold compress area can simultaneously pressurize and massage the part of the body to be treated; after the pressurized massage, the controller 15 controls the first airbag 141 to deflate, so that the hot and cold compress area can simultaneously depressurize and massage the part of the body to be treated.

[0078] When hot compress is selected, the controller 15 controls the hot and cold compress component 13 to perform heating, so that the temperature of the hot and cold compress area is maintained in the second set temperature zone; during the hot compress process, the controller 15 simultaneously controls the first airbag 141 to inflate intermittently, and keeps the first airbag 141 in an inflated state for a set time, so that the hot and cold compress area gradually increases pressure and massages the part of the body to be treated.

[0079] When selecting alternating hot and cold compresses, the controller 15 controls the hot and cold compress component 13 to perform cooling or heating; after the hot and cold compress component 13 performs cooling and keeps the first airbag 141 inflated for a set time, the hot and cold compress component 13 performs heating, and simultaneously the first airbag 141 is intermittently inflated and deflated, so that the hot and cold compress area provides alternating hot and cold compresses to the body part to be treated while simultaneously providing pressure massage; or

[0080] When the hot and cold compress component 13 heats up and keeps the first airbag 141 inflated for a set time, the hot and cold compress component 13 cools down and simultaneously inflates and deflates the first airbag 141 intermittently, so that the hot and cold compress area can perform alternating hot and cold compresses on the part of the body to be treated while simultaneously performing pressure-increasing massage.

[0081] In this control method, the duration of cold and hot compresses can be selected according to actual rehabilitation needs during the alternating hot and cold compress process. For example, a 2-minute cold compress can be applied first, causing the hot and cold compress component 13 to cool and simultaneously inflate the first airbag 141 for pressurization and massage. During the cold compress, pressure-increasing and depressurization massage can be performed alternately. Afterward, the cold compress is stopped and the first airbag 141 is deflated. Then, a 2-minute hot compress is applied, causing the hot and cold compress component 13 to heat and simultaneously inflate the first airbag 141 for pressurization and massage. During the hot compress, pressure-increasing and depressurization massage can be performed alternately. Afterward, the hot compress is stopped and the first airbag 141 is deflated. The aforementioned alternating cold and hot compress steps are then repeated. It is understood that the aforementioned set time can be 5 minutes, 10 minutes, or 30 minutes, etc., and the time can be set according to actual needs.

[0082] In some embodiments, the control method further includes:

[0083] During cold compress, the controller 15 controls the cold and hot compress components 13 and 18 to perform cooling, keeping the temperature of the cold and hot compress area within the first set temperature range; the controller 15 also controls the first airbag 141 and / or the second airbag 171 to inflate, and keeps the first airbag 141 and / or the second airbag 171 inflated for a set time, so that the cold and hot compress area provides synchronous pressure massage to the part of the body to be treated; after the pressure massage, the controller 15 controls the first airbag 141 and / or the second airbag 171 to deflate, so that the cold and hot compress area provides synchronous decompression massage to the part of the body to be treated;

[0084] During hot compress, the controller 15 controls the hot and cold compress components 13 and 18 to generate heat, keeping the temperature of the hot and cold compress area in the second set temperature range. Simultaneously, the controller 15 controls the first airbag 141 and / or the second airbag 171 to inflate intermittently, and keeps the first airbag 141 and / or the second airbag 171 in an inflated state for a set time, so that the hot and cold compress area gradually increases pressure and massages the part of the human body to be treated.

[0085] During alternating hot and cold compresses, the controller 15 controls the hot and cold compress component 13 and the second hot and cold compress component 18 to perform cooling or heating respectively. When the hot and cold compress component 13 performs cooling, the second hot and cold compress component 18 is simultaneously heated, and the first airbag 141 and / or the second airbag 171 are intermittently inflated, so that the hot and cold compress area gradually increases pressure and massages the part of the body to be treated while performing alternating hot and cold compresses.

[0086] The control method provided in the foregoing embodiments of this application can precisely control the temperature of hot and cold compresses, and effectively transfer the temperature of both to the skin surface that is in contact with the flexible hot and cold compress area. Simultaneously, the controller 15 can control the inflation and deflation of the first airbag 141 and the second airbag 171. Therefore, when applying alternating hot and cold compresses to the injured area, the pressure of the hot and cold compress areas can be adjusted synchronously, and pressure-reducing massage can be performed simultaneously, effectively improving the rehabilitation effect on the injured area.

All embodiments obtained by any modifications, alterations or equivalent substitutions made by those skilled in the art without departing from the technical concept of this application shall fall within the scope of protection of the claims of this application.
