[0009] By adopting the technical scheme, the hydrogel dressing core is polymerized by a hydrophilic group, and purified water is contained in the hydrogel dressing core, so that a dry wound surface is subjected to a hydration reaction, the wound surface is promoted to restore a wet balance, the skin feels cool, and pain of the wound is relieved.

[0010] The peeling part is arranged at the middle of the skin-friendly film, and the peeling part is attached with a colored layer.

[0011] By adopting the technical scheme, the main fixing film, the auxiliary fixing film and the main body of the skin-friendly film are made of a translucent material, the wound is easily observed, the position of the peeling part is easily identified through the colored layer, and convenience is improved.

[0012] The side surface of the peeling part is in a wave shape.

[0013] By adopting the technical scheme, when a finger contacts the peeling part, the wave-shaped structure increases the contact area of the peeling part with the finger, the main fixing film and the auxiliary fixing film are easily torn, and the finger is prevented from touching the wound.

[0014] Compared with the prior art, the utility model has the advantages that:

[0015] 1. The fixing assembly is added on the basis of the original dressing part, the main fixing film and the auxiliary fixing film are used for auxiliary fixing, the dressing part is always kept in a fixed state, and the dressing is not folded in the process of moving the dressing.

[0016] 2. When the dressing is attached to the skin surface, the main fixing film and the auxiliary fixing film are naturally separated from the skin-friendly film at the peeling part by pressing both sides of the dressing, and the efficiency of dressing change is improved.

[0017] 3. The hydrogel dressing core is polymerized by a hydrophilic group, and purified water is contained in the hydrogel dressing core, so that a dry wound surface is subjected to a hydration reaction, the wound surface is promoted to restore a wet balance, the skin feels cool, and pain of the wound is relieved.

[0024] like Figure 1 As shown, this embodiment provides a gel-type alginate dressing, including a dressing component 1, and a fixing component and an isolation component wrapped around the upper and lower sides of the dressing component 1. The fixing component includes a skin-friendly film 2 attached to the upper part of the dressing component 1, and a main fixing film 3 and a secondary fixing film 4 covering the upper part of the skin-friendly film 2. The dressing component 1 is located at the center of the skin-friendly film 2, and the skin-friendly film 2 is provided with an adhesive layer 7 around its perimeter for adhering to the skin. The shape formed by the combination of the main fixing film 3 and the secondary fixing film 4 is the same as the shape of the skin-friendly film 2, and a peeling part 8 is formed at the connection between the main fixing film 3 and the secondary fixing film 4. The isolation component includes a main release paper 5 and a secondary release paper 6 that are staggered, and the main release paper 5 and the secondary release paper 6 are attached to the lower part of the dressing component 1 by the adhesive layer 7.

[0025] In this embodiment, both the skin-friendly membrane 2 and the dressing 1 are rectangular. The dressing 1 is attached to the center of the skin-friendly membrane 2. The fixing membrane 3 and the secondary fixing membrane 4 are distributed on both sides of the skin-friendly membrane 2. Since the skin surface is curved, when the dressing is attached to the skin surface, the skin-friendly membrane 2 is relatively soft and naturally adheres to the skin surface. The main fixing membrane 3 and the secondary fixing membrane 4 are relatively hard and naturally separate from the skin-friendly membrane 2 from the peeling part 8. At this time, the main fixing membrane 3 and the secondary fixing membrane 4 can be completely separated simply by grasping the peeling part 8. The overall operation is simple and convenient.

[0026] In this embodiment, the dressing 1 is a hydrogel dressing core, and purified water is attached inside the hydrogel dressing core. The hydrogel dressing core is made of polymer with hydrophilic groups and contains purified water, which causes the dry wound to undergo a hydration reaction, promotes the restoration of the wound's moisture balance, makes the skin feel cool, and relieves the pain of the wound.

[0027] In the embodiment, the peeling part 8 is arranged on the central axis of the skin-friendly film 2, the peeling part 8 is attached with the colored layer 9, the main fixed film 3, the auxiliary fixed film 4 and the main body of the skin-friendly film 2 are made of translucent material, the wound can be observed, the position of the peeling part 8 can be obviously recognized through the colored layer 9, and convenience is improved.

[0028] In the embodiment, the side surface of the peeling part 8 is in a wavy shape, when the finger contacts the peeling part 8, the wavy structure increases the contact area of the peeling part 8 with the finger, and the main fixed film 3 and the auxiliary fixed film 4 are conveniently torn.

[0029] Combining Figures 2-4 As shown in the use method of the utility model, the wound is cleaned and the skin around the wound is wiped dry, the dressing patch is taken out, the main release paper 5 and the auxiliary release paper 6 are sequentially torn, and the hydrogel dressing core is covered on the wound, so that the adhesive layer 7 of the skin-friendly film 2 is completely attached to the skin, and the dressing patch is smoothed from the two sides of the main fixed film 3 and the auxiliary fixed film 4, at this time, the main fixed film 3 and the auxiliary fixed film 4 are warped from the "S" line of the peeling part 8,

[0030] After the main fixed film 3 and the auxiliary fixed film 4 are torn, only the hydrogel dressing core and the skin-friendly film 2 are left, so that the dressing is changed.

[0031] In addition to the above-mentioned embodiments, the utility model can also have other implementation manners. Any technical scheme formed by equivalent replacement or equivalent transformation falls within the protection scope required by the utility model.
