Abstract
Description
Technical Field
[0001] This invention relates to the field of medical hydrogel film technology, specifically to a sterile medical hydrogel film. Background Technology
[0002] Medical hydrogel films are film structures made primarily of medical hydrogel. Medical hydrogel is semi-permeable and has the effects of blocking bacteria, preventing wound infection, and allowing oxygen and water to pass through.
[0003] When using medical hydrogel patches, the hydrogel needs to be applied to the patient's wound site and fixed to the patient's body. The existing fixation method is usually to stick the hydrogel patch to the patient's body with adhesive, which may cause discomfort to the patient. Summary of the Invention
[0004] Therefore, this invention proposes a sterile medical hydrogel patch to reduce discomfort when fixed to a patient.
[0005] The technical solution of the present invention is as follows: A sterile medical hydrogel patch includes a hydrogel layer, a first protective layer disposed inside the hydrogel layer, and a second protective layer disposed outside the hydrogel layer. It also includes a functional layer disposed between the hydrogel layer and the second protective layer. The functional layer includes a plurality of first metal sheets arranged longitudinally and spaced apart along the second protective layer, and a plurality of second metal sheets arranged transversely and spaced apart along the second protective layer. The first metal sheets and / or the second metal sheets each have inwardly folded functional ends, which can be folded outwards beyond the hydrogel layer.
[0006] Furthermore, the length of the functional end is set such that when the two functional ends of the same first metal sheet and / or the same second metal sheet are folded inward, the two functional ends can abut against each other.
[0007] Furthermore, the first metal sheet and the second metal sheet are made of 316 stainless steel.
[0008] Furthermore, the thickness of the first metal sheet and the second metal sheet is between 0.2 and 0.4 mm.
[0009] Furthermore, each of the first metal sheet and / or the second metal sheet includes a first segment and a second segment, and two clips are provided at one end of the first segment or the second segment. Correspondingly, the second segment or the first segment can slide between the two clips.
[0010] Furthermore, it also includes an insulated bag or a cold-insulating bag, which is placed on the outside of the second protective layer, and the functional ends of the first metal sheet and / or the second metal sheet can be bent upward and inward to hold the insulated bag or cold-insulating bag.
[0011] Furthermore, two protective layers are provided between the hydrogel layer and the first protective layer, respectively located on both sides of the hydrogel layer. The first ends of the two protective layers overlap in the middle of the hydrogel layer, and the second ends pass through the outside of the hydrogel layer and extend upward to be inserted between the hydrogel layer and the second protective layer.
[0012] Furthermore, one of the two protective layers has a through hole at its first end, and the other of the two protective layers has a pull portion at its first end that can pass through the through hole.
[0013] The working principle and beneficial effects of this invention are as follows: The sterile medical hydrogel patch provided by the present invention has a plurality of first metal sheets and second metal sheets disposed between the second protective layer and the hydrogel layer, and functional ends that can be folded outward and extend beyond the hydrogel layer are respectively provided at both ends of the first metal sheets and the second metal sheets. On the one hand, the arrangement of the first metal sheets and the second metal sheets can better maintain the shape of the hydrogel and prevent the hydrogel from curling up. On the other hand, the hydrogel patch can be fixed by utilizing the curvature of the human arm or other parts through the completeness of the functional ends. Attached Figure Description

Detailed Implementation
[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0017] This invention provides a sterile medical hydrogel patch, which will be referred to as a hydrogel patch below. (See reference...) Figures 1 to 3 As shown, the system includes a hydrogel layer 100, a first protective layer 200 disposed inside the hydrogel layer 100, and a second protective layer 300 disposed outside the hydrogel layer 100. It also includes a functional layer 400 disposed between the hydrogel layer 100 and the second protective layer 300. The functional layer 400 includes a plurality of first metal sheets 410 arranged longitudinally and spaced apart along the second protective layer 300, and a plurality of second metal sheets 420 arranged transversely and spaced apart along the second protective layer 300. Each of the first metal sheets 410 and / or the second metal sheets 420 has an inwardly folded functional end 430, which can be folded outwards beyond the hydrogel layer 100. The inner side of the hydrogel layer 100 refers to the side used for contact with the human body.
[0018] Based on the overall structure described above, in use, after removing the first protective layer 200 and the second protective layer 300, the hydrogel layer 100 is attached to the area to be treated on the patient. Then, the functional ends 430 of the first metal sheet 410 and the second metal sheet 420 are bent to conform to the curvature of the arm or leg, thus fixing the hydrogel film to the arm or curvature. It should be noted that if the film is to be fixed to other parts of the body, the hydrogel layer 100 still needs to be glued to the body.
[0019] It should be noted that the aforementioned first metal sheet 410 and / or second metal sheet 420 each have an inwardly folding functional end 430. Specifically, the functional end 430 can be provided only at both ends of each first metal sheet 410, or only at both ends of each second metal sheet 420, or the functional end 430 can be provided at both ends of each first metal sheet 410 and each second metal sheet 420.
[0020] Specifically, the hydrogel layer 100, the first protective layer 200, and the second protective layer 300 in this embodiment can all be existing products, and their structures and materials will not be described in detail here. Compared with existing hydrogel films, the hydrogel film in this embodiment has several longitudinally and transversely arranged metal sheets set on the outer side of the hydrogel layer 100. By bending each metal sheet, it is convenient to fix the hydrogel to curved parts of the human body such as the arm or leg.
[0021] In terms of specific structure, each of the first metal sheet 410 and / or the second metal sheet 420 in this embodiment includes a first segment 440 and a second segment 450, respectively. Two clips are provided at one end of the first segment 440 or the second segment 450, allowing the second segment 450 or the first segment 440 to slide between the two clips. Specifically, in this embodiment, two clips are provided at one end of the second segment 450, and a guide post is provided between the two clips. An elongated hole is formed in the first segment 440, and the sliding of the guide post within the elongated hole guides the sliding of the first segment 440.
[0022] By setting the first metal sheet 410 and the second metal sheet 420 as described above, the length of the first metal sheet 410 or the second metal sheet 420 can be adjusted by adjusting the position of the first segment 440. On the one hand, this makes the hydrogel film suitable for people of different body types; on the other hand, by increasing the length of the first metal sheet 410 and the second metal sheet 420, the following heat preservation bags or cold preservation bags can be better clamped.
[0023] In this embodiment, the first metal sheet 410 and the second metal sheet 420 are preferably made of 316 stainless steel. It should be noted that the first metal sheet 410 and the second metal sheet 420 can also be made of other skin-friendly metals such as titanium. In this embodiment, the thickness of the first metal sheet 410 and the second metal sheet 420 is between 0.2 and 0.4 mm, specifically, it can be 0.2 mm, 0.3 mm, or 0.4 mm, or any other value between 0.2 mm and 0.4 mm.
[0024] The hydrogel film in this embodiment also includes an insulated bag or a cold insulated bag, which is placed on the outside of the second protective layer 300, and the functional ends 430 of the first metal sheet 410 and / or the second metal sheet 420 can be bent upward and inward to hold the insulated bag or cold insulated bag.
[0025] Specifically, when applying hydrogel films, there may be a need for cold or hot compresses. In this embodiment, by setting the aforementioned first metal sheets 410 and second metal sheets 420, in addition to using the functional ends 430 of the first metal sheets 410 and second metal sheets 420 to fix the hydrogel outside the body, it is also possible to make some of the functional ends 430 of the first metal sheets 410 and second metal sheets 420, as... Figure 4 As shown, the material is folded upwards and inwards to hold the insulating or cooling bag placed on the outside of the hydrogel, thus facilitating hot or cold compresses. The insulating bag can be a bag filled with warm water, while the cooling bag is a bag filled with cold water. It should be noted that, for ease of understanding, the insulating or cooling bag is not shown in the accompanying drawings of this embodiment.
[0026] refer to Figure 1 and Figure 5 As shown, in this embodiment, two protective layers 500 are respectively located on both sides of the hydrogel layer 100 between the hydrogel layer 100 and the first protective layer 200. The first ends of the two protective layers 500 overlap in the middle of the hydrogel layer 100, and the second ends pass through the outer side of the hydrogel layer 100 and extend upward to be inserted between the hydrogel layer 100 and the second protective layer 300. Furthermore, one of the two protective layers 500 has a through hole 501 at its first end, and the other of the two protective layers 500 has a pulling portion 510 that can pass through the through hole 501 at its first end.
[0027] In this embodiment, by setting the above-mentioned protective layer 500, on the one hand, the hydrogel layer 100 can be better protected to prevent bacterial invasion before use. On the other hand, when applying the hydrogel film, the operator can pull the pulling part 510 with one hand and pull the other protective layer 500 with the other hand, so that the operator's hands do not need to touch the inner surface of the hydrogel layer 100 to complete the application of the hydrogel layer 100 to the human body, reducing the risk of bacteria on the hands sticking to the inner surface of the hydrogel film.
[0028] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
