Description

Technical Field

[0001] This utility model relates to the field of cold compresses, and more particularly to a portable, readily available cold compress. Background Technology

[0002] Cold compresses are a physical therapy method that reduces blood circulation and the release and spread of inflammatory mediators by lowering local temperature, thereby relieving pain, swelling, muscle spasms, and promoting tissue repair. Cold compresses are widely used in daily life, such as for routine care, sprains and bruises, facial treatments, and post-sun exposure recovery.

[0003] Existing cold compress tools include various forms such as cold compress machines, cold compress bags, and cold compress patches. Cold compress machines are expensive, bulky, and difficult to move, so they are often used in special scenarios such as medical treatment and sports training. Cold compress bags and cold compress patches are more convenient and quick to use, so people often use cold compress bags and cold compress patches as cold compress tools in daily life.

[0004] Cold compresses and ice packs typically need to be frozen or refrigerated before use to reach a low temperature for application. Furthermore, these items are usually held by the user, causing inconvenience and discomfort to the hands due to the low temperature. The warmth of the hands also accelerates the melting and warming of the compress or ice pack, shortening the application time. Utility model patent CN201755274U provides a nasal cold compress bag with an inverted "T"-shaped hollow structure. The hollow center is a filling area that can be filled with a special energy-storing material. The outer surface of the nasal cold compress bag is made of PVC material, with sealed edges around the perimeter. Sealing loops are located on both sides of the filling area, with holes for attaching elastic cords to secure the head. This makes the nasal cold compress bag soft and comfortable while being easy to secure. However, the aforementioned nasal cooling pack still needs to be refrigerated before it can be used, and refrigeration often requires a long refrigeration time, making it difficult to meet the need for cooling in sudden situations in daily life. Summary of the Invention

[0005] In view of this, the present invention provides a portable, readily available cold compress to solve the above problems.

[0006] A portable, ready-to-use cold compress includes an applicator and at least one strap fixed to the applicator. The applicator includes an applicator body, a liquid reservoir within the applicator body, a refrigerant reservoir within the applicator body, a diaphragm layer between the liquid reservoir and the refrigerant reservoir, and at least one divider strip on the applicator body. The divider strip divides the applicator body into multiple independent sections corresponding to human anatomy. The applicator body has a double-layer structure. The diaphragm layer is disposed between the two layers of the applicator body. A refrigerant for cooling and a solution for reacting with the refrigerant are respectively encapsulated in the refrigerant reservoir and the liquid reservoir. The edge portion of the diaphragm layer is pressed together with the edge portion of the applicator body, thereby separating the refrigerant and solution within the refrigerant reservoir and the liquid reservoir.

[0007] Furthermore, the diaphragm layer is made of a plastic film.

[0008] Furthermore, the separating strip is spaced between the two layers of the dressing body according to the human body structure, and it is formed by hot pressing, ultrasonic welding or high-frequency welding of the dressing body and the diaphragm layer together.

[0009] Furthermore, the strap can be a fixed strap or a telescopic strap. When the strap is a telescopic strap, it is made of elastic cord. When the strap is a fixed strap, it is provided with an adjustment buckle to adjust the length of the strap.

[0010] Furthermore, the patch includes a patch body, a receiving cavity located between the patch bodies, a plurality of liquid pouches disposed within the receiving cavity, and a plurality of separating strips disposed on the patch body.

[0011] Furthermore, the liquid pouch is made of a plastic film that encapsulates the liquid, and each independent area separated by the dividing strip contains at least one of the liquid pouches.

[0012] Furthermore, the patch includes a patch body and a plurality of dividing strips disposed on the patch body, and a plurality of water inlets are disposed on the patch body.

[0013] Furthermore, each of the water inlets is connected to the receiving cavity formed by the patch body, and each independent area of ​​the patch body separated by the dividing strip is provided with at least one water inlet.

[0014] Compared with existing technologies, the portable, ready-to-use cold compress provided by this utility model has a double-layer structure for the cold compress body, with a membrane layer between the two layers. This divides the cold compress body into a liquid storage section for containing the solution and a refrigerant storage section for containing the refrigerant. Furthermore, a separator band further divides the compress body into sections. When using the cold compress, simply squeeze the membrane layer in the corresponding area to allow the solution in the liquid storage section to come into contact with the refrigerant in the refrigerant storage section, causing a reaction that rapidly cools the cold compress body for application. Therefore, this convenient cold compress saves the freezing time of ordinary cold compresses, ice packs, and other cold compress methods, making it readily available and providing a longer-lasting effect. Additionally, the compress body is equipped with an adjustable strap for easy wear without hindering the user's movement. Attached Figure Description

[0020] The specific embodiments of this utility model will be described in further detail below. It should be understood that the description of this utility model herein is not intended to limit the scope of protection of this utility model.

[0021] like Figures 1 to 2 The diagram shown is a structural schematic of a portable, ready-to-use cold compress provided in the first embodiment of this utility model. The portable, ready-to-use cold compress includes a patch body 10 and at least one strap 20 fixedly disposed on the patch body 10. The portable, ready-to-use cold compress may also include other functional components, such as assembly components and encapsulation components, which are all prior art known to those skilled in the art and will not be described in detail here.

[0022] The dressing 10 includes a dressing body 11, a liquid storage section 12 disposed within the dressing body 11, a refrigerant containment section 13 disposed within the dressing body 11, a membrane layer 14 located between the liquid storage section 12 and the refrigerant containment section 13, and at least one separating strip 15 disposed on the dressing body 11.

[0023] The patch body 11 should be made of a skin-friendly and soft material, such as silicone, rubber, or flexible plastic, so that the patch body 11 can better conform to the human body during application and provide a more comfortable feel. The patch body 11 has a double-layer structure, and the edges of the two layers of the patch body 11 can be fixed together by hot pressing, ultrasonic welding, or high-frequency welding, thereby forming a receiving cavity between the two layers of the patch body 11. This receiving cavity is used to house the liquid storage part 12 and the refrigerant receiving part 13. The shape of the patch body 11 can be specifically designed according to the part of the human body it is used on, such as the arm, leg, or back, so that it can adapt to the human body structure and fit more effectively during application. In this embodiment, the structure of the patch body 11 is adapted to the human face.

[0024] The liquid storage section 12 is located on one side of the diaphragm layer 14 and is composed of the patch body 11 and the diaphragm layer 14. It is used to store liquids that react with the refrigerant, such as water or other solutions.

[0025] The refrigerant container 13 is located on the side opposite to the diaphragm layer 14 and the liquid storage section 12, and is used to store refrigerant. This refrigerant can be a solid refrigerant, such as ammonium chloride, boric acid, or carbamide. When the refrigerant encounters the solution, a heat of dissolution effect occurs, meaning the solid refrigerant dissolves and absorbs surrounding heat, thereby lowering the temperature of the patch body 11. When the refrigerant in the refrigerant container 13 reacts with the solution in the liquid storage section 12, the temperature of the patch body 11 can typically drop to approximately 2°C-8°C, and the reaction time at 15°C can last for approximately 15-25 minutes. Specifically, different types of refrigerants can be filled into the refrigerant container 13 according to the application requirements, ensuring the reaction time meets the needs of a single application. Furthermore, the temperature range of the patch body 11 during the cooling reaction can be adjusted by controlling the amount of refrigerant added.

[0026] The diaphragm layer 14 can be made of plastic film, with its edges pressed together with the edges of the patch body 11. When the cold compress is not in use, the refrigerant and the solution for reacting with the refrigerant are respectively encapsulated in the refrigerant container 13 and the liquid storage container 12, and separated by the diaphragm layer 14. When using the portable, ready-to-use cold compress, the diaphragm layer 14 can be ruptured by squeezing, allowing the solution in the liquid storage container 12 to mix with the refrigerant in the refrigerant container 13 and react to rapidly cool down, thereby providing a lower temperature for cold compress on the human body.

[0027] The separator 15 can be spaced between the two layers of the patch body 11 according to the human body structure. It is formed by hot pressing, high-frequency welding, or ultrasonic welding of the two layers of the patch body 11 and the diaphragm layer 14 together. The separator 15 divides the patch body 10 into multiple independent parts corresponding to the human body structure. In this embodiment, the separator 15 divides the patch body 10 into independent areas corresponding to the forehead, cheeks, and chin, so that it can be applied to the area that needs cold compress during use, thereby avoiding discomfort to other non-applied areas caused by low temperature. It is understood that, if necessary, multiple separators 15 can be added to further subdivide the patch body 11.

[0028] The two ends of the strap 20 can be fixed to both sides of the patch body 11 by hot pressing, high-temperature welding, or ultrasonic welding, making it convenient to wear on the body when using this portable, ready-to-use cold compress. Additionally, two or more straps 20 can be arranged side-by-side according to usage requirements, thereby improving the wearing stability of the portable, ready-to-use cold compress. The strap 20 can be a fixed strap or a retractable strap. When the strap 20 is a retractable strap, it can be made of an elastic material such as elastic cord to improve its size adaptability. When the strap 20 is a non-elastic fixed strap, an adjustable buckle or other length-adjustable component can be added to the strap 20 to adjust its length.

[0029] Compared with the prior art, the portable, ready-to-use cold compress provided by this utility model has a double-layer structure for its applicator body 11, with a membrane layer 14 between the two layers, thus dividing the cold compress body 11 into a liquid storage section 12 for containing the solution and a refrigerant storage section 13 for containing the refrigerant. Furthermore, a separating band 15 further divides the applicator body 11 into sections. When using the cold compress, simply puncture the membrane layer 14 in the corresponding area, allowing the solution in the liquid storage section 12 to react with the refrigerant in the refrigerant storage section 13, causing the cold compress body 11 to cool rapidly and thus provide a cold compress to the body. Therefore, this convenient cold compress saves the freezing time of ordinary cold compresses, ice packs, and other cold compress methods, making it ready to use immediately and providing a longer-lasting effect than ice packs. Meanwhile, the dressing body 10 is also equipped with an adjustable strap 20 for easy wearing without affecting the user's movement.

[0030] like Figures 3 to 4 The diagram shown is a structural schematic of a second embodiment of a convenient, ready-to-use cold compress provided by this utility model. The convenient, ready-to-use cold compress includes a patch body 30 and at least one strap 40 fixedly disposed on the patch body 30. Compared with the first embodiment, the second embodiment differs only in the patch body 30; the strap 40 and the strap 20 have the same purpose and structure, therefore, the strap 40 will not be described in detail here. Only the patch body 30 will be described in further detail below.

[0031] The patch 30 includes a patch body 31, a receiving cavity 32 located between the patch bodies 31, a plurality of liquid pouches 33 disposed in the receiving cavity 32, and a plurality of separating strips 34 disposed on the patch body 31.

[0032] The dressing body 31 is made of a skin-friendly and soft material, such as silicone, which allows it to conform better to the human body during application and provides a more comfortable feel. The dressing body 31 has a double-layer structure, and the edges of the two layers can be fixed together by heat pressing, thereby forming the receiving cavity 32 between the two layers. The structure of the dressing body 31 is the same as that of the dressing body 11, and will not be described further here.

[0033] The accommodating cavity 32 is used to contain the refrigerant and the liquid bag 33 for dissolving the refrigerant, thereby replacing the liquid storage section 12 and the refrigerant accommodating section 13 in the first embodiment.

[0034] The liquid pouch 33 can be made by wrapping the solution in a plastic film. The size of the liquid pouch 33 can be set according to the refrigerant content within its reaction range to ensure that the solution in the liquid pouch 33 can fully react with the refrigerant in the accommodating cavity 32 within the area. When manufacturing the patch 30, the refrigerant is loaded into the accommodating cavity 32, and the individual liquid pouch 33 is also loaded and sealed together. The individual liquid pouch 33 replaces the diaphragm layer 14 and the liquid storage section 12, making the manufacturing of the patch 10 simpler and more convenient.

[0035] The separator 34 has the same structure and function as the separator 15, serving to divide the dressing body 31 into multiple independent areas, thereby facilitating localized cold compress effects. It is understood that each independent area separated by the separator 34 should contain at least one of the liquid pouches 33.

[0036] like Figure 5 The diagram shown is a structural schematic of a third embodiment of a convenient, ready-to-use cold compress provided by this utility model. The convenient, ready-to-use cold compress includes a patch body 50 and a plurality of water inlets 60 disposed on the patch body 50.

[0037] The dressing 50 includes a dressing body 51 and a plurality of separating strips 52 disposed on the dressing body 51.

[0038] The patch body 51 is made of a skin-friendly and soft material, such as silicone or rubber, so that it can better conform to the human body during application and provide a more comfortable feel. The patch body 51 has a double-layer structure. The edges of the two layers of the patch body 51 are pressed together to form a cavity between them, in which the refrigerant for cooling is encapsulated.

[0039] The separator 52 has the same structure and function as the separator 15, and is used to divide the patch body 51 into multiple independent areas, thereby facilitating the local cold compress effect. Further details will not be provided here.

[0040] The water inlet 60 can be disposed on the patch body 51 along the outer contour of the patch body 51, and is used to inject a solution into the accommodating cavity formed by the patch body 51. After the solution is injected, it reacts with the refrigerant in the accommodating cavity, thereby allowing the patch body 51 to cool down rapidly. Each independent area of ​​the patch body 51 separated by the dividing strip 52 is provided with at least one water inlet 60. One end of the water inlet 60 is connected to the accommodating cavity formed by the patch body 51, and the other end should be provided with an end cap or valve (not shown) to seal it. When using the cold compress, the sealed end cap or valve at the water inlet 60 is opened, and the reaction solution can be injected into the accommodating cavity using a syringe, water bag, etc. Alternatively, a liquid bag made according to the size of the water inlet 60 can be inserted into the accommodating cavity through the water inlet 60.

[0041] Compared with the first and second embodiments, in this embodiment, the reaction solution is injected into the accommodating cavity formed by the patch body 51 only when the cold compress is in use, thereby avoiding the accidental rupture of the diaphragm layer 14 in the first embodiment and the liquid bag 33 in the second embodiment before use, which would cause the refrigerant to fail.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
