Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to a head cooling device for emergency care. Background Technology
[0002] Cooling patches, also known as fever-reducing patches or cooling compresses, were initially developed to address some of the problems with ice packs. Ice packs required repeated cooling, were inconvenient when shared by multiple people, had a short cooling time, and could easily cause frostbite to children. Cooling patches, on the other hand, utilize the principle of heat absorption during water vaporization. Through this physical change, heat is absorbed from the body, thus lowering body temperature. As a physical cooling product, it is widely used for fever relief, heatstroke prevention, and high-temperature work scenarios due to its unique cooling method.
[0003] However, current cooling patches generally use a rectangular structure, which results in a relatively small contact area with the forehead and the application area cannot be adjusted. This smaller contact area also reduces the heat transfer area, limiting their cooling effect in situations requiring urgent cooling. Utility Model Content
[0004] The purpose of this invention is to provide a head cooling device for emergency care, which has a large application area and can adjust the application area of the hydrogel according to the patient's forehead area, thus having good flexibility.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An emergency care head cooling device includes a sheet-like hydrogel body comprising: a first gel section, at least one second gel section, and a third gel section.
[0007] The first gel section has an extension portion, which is at least used for application to the patient's glabella.
[0008] The at least one second gel partition is located above the first gel partition.
[0009] The third gel partition is located above the first gel partition and is located to the side of the at least one second gel partition.
[0010] The at least one second gel partition has a first separation region between it and the first gel partition.
[0011] The third gel partition has a second separating area between it and the first gel partition.
[0012] The thickness of the first dividing region and the second dividing region is less than the thickness of the first gel partition and / or at least one second gel partition and / or the third gel partition.
[0013] In at least one embodiment of the emergency care head cooling device provided in this disclosure, the second gel section is arranged in a semi-circular shape.
[0014] Both the first gel partition and the third gel partition are T-shaped.
[0015] In at least one embodiment of the emergency care head cooling device provided in this disclosure, the areas of the second gel partition and the third gel partition are both smaller than the area of the first gel partition.
[0016] In at least one embodiment of the emergency care head cooling device provided in this disclosure, a plurality of air vents are provided on the first gel partition and / or at least one second gel partition and / or a third gel partition.
[0017] In at least one embodiment of the emergency care head cooling device provided in this disclosure, the extension is located in the middle of the first gel partition.
[0018] The thickness of the extension is less than the thickness of the first gel partition.
[0019] In at least one embodiment of the emergency care head cooling device provided in this disclosure, at least one pre-tear mark is provided on the third gel section.
[0020] In at least one embodiment of the emergency care head cooling device provided in this disclosure, the pre-tear marks are arranged in an arc shape.
[0021] The outer periphery of the top of the third gel partition is arc-shaped, and the arc direction of the outer periphery of the top of the third gel partition is opposite to that of the pre-tear line.
[0022] In at least one embodiment of the emergency care head cooling device provided in this disclosure, the extension is also used to be applied to the bridge of the patient's nose.
[0023] In at least one embodiment of the emergency care head cooling device provided in this disclosure, the front of the hydrogel body is applied to the patient's body surface, and the back of the hydrogel body is provided with a first adhesive portion and a second adhesive portion.
[0024] The first adhesive part is used to position the second gel in sections.
[0025] The second adhesive part is used to position the third gel partition.
[0026] The head cooling device for emergency care provided in at least one embodiment of this disclosure also includes a restraint strap.
[0027] The two ends of the restraint strap are respectively fixedly connected to the two ends of the first gel partition.
[0028] The beneficial effects of this invention are as follows: it adopts a multi-zone design, and each zone can flexibly adapt to changes in the shape of the forehead. This design allows for adjustment of the contact area between the hydrogel and the human forehead, demonstrating excellent flexibility.
[0029] The hydrogel body provides a larger contact area with the patient's forehead. Its multi-zone design allows for a close fit to the forehead's contours, ensuring good contact with both raised and recessed areas. Each zone can independently adjust its fit to the forehead's surface, significantly increasing the contact area and enabling more efficient transfer of cooling energy, thus enhancing the cooling effect.

[0043] The technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments, not all embodiments.
[0044] Example 1
[0045] like Figure 1 , 2 As shown in Figure 8, this embodiment provides a head cooling device for emergency care, including a sheet-like hydrogel body 10, which has a first gel section 11, a second gel section 12 and a third gel section 13.
[0046] Specifically, the first gel section 11 has an extension 111, which is used to apply the gel to the patient's glabella. By providing the extension 111, the overall contact area with the patient can be increased, thereby enhancing the cooling effect.
[0047] Specifically, the second gel partition 12 is located above the first gel partition 11. The third gel partition 13 is located above the first gel partition 11 and is located to the side of the second gel partition 12.
[0048] Specifically, a first separating region 121 is provided between the second gel partition 12 and the first gel partition 11. A second separating region 131 is provided between the third gel partition 13 and the first gel partition 11. The thickness of both the first separating region 121 and the second separating region 131 is less than the thickness of each gel partition.
[0049] Because the first dividing area 121 and the second dividing area 131 are thin, it is convenient to fold the second gel partition 12 and the third gel partition 13.
[0050] When in use, medical staff can use the second gel section 12 and the third gel section 13 according to their needs and the shape of the patient's forehead. When the second gel section 12 and the third gel section 13 are not needed, they can be folded and pressed against the back of the first gel section 11. This not only adjusts the contact area between the hydrogel and the patient's forehead, but also allows the heat from the first gel section 11 to be transferred to the second gel section 12 and the third gel section 13, resulting in a better cooling effect.
[0051] In this embodiment, the second gel partition 12 is semi-circular, and there are two second gel partitions 12; the semi-circular design of the second gel partition 12 is well adapted to patients with an M-shaped hairline.
[0052] Specifically, both the first gel section 11 and the third gel section 13 are T-shaped. The outer periphery of the top of the third gel section 13 is arc-shaped, which is beneficial for use on patients with high hairlines.
[0053] Specifically, a pre-tear line 132 is provided on the third gel partition 13. The pre-tear line 132 is arc-shaped, and the outer periphery of the top of the third gel partition 13 is opposite to the arc direction of the pre-tear line 132.
[0054] When in use, the third gel section 13 can be torn along the direction of the pre-tear line 132, which allows the user to easily adjust the shape of the third gel section 13 according to the patient's hairline, making it highly flexible.
[0055] In this embodiment, the areas of the second gel partition 12 and the third gel partition 13 are both smaller than the area of the first gel partition 11.
[0056] In this embodiment, the extension 111 is located in the middle of the first gel partition 11; the thickness of the extension 111 is less than the thickness of the first gel partition 11.
[0057] The extension 111 has a smaller thickness, which facilitates its deformation and makes it easier to adhere to the patient's glabella.
[0058] In this embodiment, the hydrogel body 10 is composed of a gel layer and a non-woven fabric layer, and the gel layer and the non-woven fabric layer are bonded together.
[0059] Example 2
[0060] like Figure 3 As shown, this embodiment provides a head cooling device for emergency care, which differs from Embodiment 1 in that the extension 111 is longer and is also used to be applied to the patient's nose bridge.
[0061] Example 3
[0062] like Figure 4 As shown, this embodiment provides a head cooling device for emergency care, which differs from Embodiment 1 in that the first gel partition 11 and the second gel partition 12 are provided with multiple air vents 20.
[0063] Example 4
[0064] like Figure 5 As shown, this embodiment provides a head cooling device for emergency care, which differs from Embodiment 1 in that the second gel partition 12 and the third gel partition 13 are provided with multiple air vents 20.
[0065] Example 5
[0066] like Figure 6 As shown, this embodiment provides a head cooling device for emergency care, which differs from Embodiment 1 in that it also includes a restraint strap 30.
[0067] Specifically, both ends of the binding strap 30 are fixedly connected to the non-woven fabric layer, and the two ends of the binding strap 30 are respectively fixedly connected to the two ends of the first gel partition 11.
[0068] Example 6
[0069] like Figure 7 and 8 As shown, this embodiment provides a head cooling device for emergency care, which differs from Embodiment 1 in that the front of the hydrogel body 10 is a gel layer for application to the patient's body surface; the back of the hydrogel body 10 is a non-woven fabric layer, and the non-woven fabric layer is provided with a first adhesive part 14 and a second adhesive part 15.
[0070] Specifically, the first adhesive part 14 is used to position the second gel section 12. The second adhesive part 15 is used to position the third gel section.
[0071] For example, both the first adhesive part 14 and the second adhesive part 15 are double-sided adhesive.
[0072] Although embodiments of this application have been shown and described above, the scope of protection of this utility model is not limited thereto. Any changes or substitutions that can be conceived without inventive effort should be included within the scope of protection of this utility model. Unless expressly stated otherwise, no element, action or instruction used herein should be construed as critical or necessary.
