Description

Technical Field

[0001] The utility model relates to the technical field of hydrocolloid dressings, in particular to a hydrocolloid dressing with an extension part. Background Art

[0002] Hydrocolloid dressings are made by mixing elastic polymer hydrogels with synthetic rubber and adhesives. The most common gel in dressings is carboxymethyl cellulose, which can be firmly attached to the skin at the edge of the wound and can swell 12 times after absorbing exudate. After absorbing exudate, the hydrophilic particles in the dressing can form a semi-solid substance similar to gel, which adheres to the base of the wound, providing and maintaining a moist environment that is conducive to wound healing. Hydrocolloid dressings have the characteristics of absorbing wound exudate. After absorbing exudate, a closed moist environment will be formed around the wound, which can form a closed wound. The closed healing environment can promote the proliferation of microvessels and the formation of granulation tissue, thereby accelerating wound healing. In addition, hydrocolloid dressings also have the function of debridement. Hydrocolloids contain endogenous enzymes that can promote the dissolution of fibrin. On the other hand, the closed environment provided by hydrocolloid dressings is conducive to the removal of necrotic tissue by macrophages. Hydrocolloid dressings can be used to treat a variety of different wounds, especially for chronic and difficult-to-heal wounds. The absorbency and viscosity of hydrocolloids enable them to meet the basic requirements of an ideal dressing, namely protecting the wound, providing a suitable environment to promote wound healing, and being easy to remove without damaging new tissue.

[0003] When the existing hydrocolloid dressing is actually used, it only has a waterproof layer on the surface, and most of them do not have antibacterial properties. When used, it is not conducive to wound healing.

[0004] After searching the existing patent: Hydrocolloid dressing (Announcement No.: CN201404369Y), the beneficial effects of this utility model are: the middle part is thick and the periphery is thin, it is easier to stick to the skin and the corners are not easy to curl up.

[0005] Although the above patent makes the corners of the hydrocolloid dressing less likely to curl up, when the wound surface discharges too much fluid instantly, some of the fluid will flow around the dressing before it can be absorbed, and after the dressing absorbs the fluid and expands, the dressing will not adhere firmly to the skin and fall off, which is not conducive to improving the use effect of the hydrocolloid dressing.

[0006] Therefore, it is necessary to invent a hydrocolloid dressing with an extension to solve the above problems. Utility Model Content

[0007] The technical problems to be solved by the utility model are as follows: when the wound surface discharges too much fluid instantly, part of the fluid will flow to the surrounding of the dressing before being absorbed, and after absorbing the fluid and swelling, the dressing will not adhere firmly to the skin and fall off, which is not convenient for improving the use effect of the hydrocolloid dressing.

[0008] The purpose of the utility model can be achieved through the following technical solutions:

[0009] A hydrocolloid dressing with an extension portion comprises a placement layer, the bottom surface of the placement layer is fixedly connected to a waterproof layer, a placement groove is provided in the middle of the placement layer, a dressing is arranged inside the placement groove, the top surface of the dressing is fixedly connected to a water-absorbing foam layer, the inner wall of the placement groove is provided with a groove, an expansion component is fixedly connected inside the groove, the top surface of the water-absorbing foam layer is fixedly connected to an absorption layer, the surface of the placement layer is fixedly connected to an adsorption layer, the top surface of the adsorption layer is fixedly connected to an antibacterial component, the surface of the antibacterial component is fixedly connected to a gelatin layer, the surface of the gelatin layer is fixedly connected to a protective strip, the surface of the gelatin layer is adhesively connected to an isolation film, the waterproof layer is fixedly connected to extension components on all sides, and the surface of the extension component is adhesively connected to protective paper.

[0010] As a further solution of the utility model: the material of the water-absorbing foam layer is polyurethane, which has water-absorbing performance and moisturizing effect.

[0011] As a further solution of the utility model: the expansion assembly includes an expansion box fixedly connected to the inside of the groove, the inner wall of the expansion box is provided with a plurality of through holes, the inside of the through holes is fixedly connected with absorbent cotton threads, and the absorbent cotton threads are convenient for absorbing the exudate after the dressing is expanded.

[0012] As a further solution of the utility model: the antibacterial component includes a protective layer fixedly connected to the surface of the adsorption layer, and a silver ion antibacterial layer is fixedly connected to the interior of the protective layer, and the silver ion antibacterial layer releases antibacterial components.

[0013] As a further solution of the utility model: the material of the protective strip is sponge, which is convenient for blocking exudate from flowing to the edge of the hydrocolloid dressing.

[0014] As a further solution of the utility model: the extension component includes elastic cellulose cloth layers fixedly connected to the waterproof layer on all sides, and the surface of the elastic cellulose cloth layer is fixedly connected to a silicone gel layer, which is easy to pull and strengthens the connection between the hydrocolloid dressing and the skin.

[0015] As a further solution of the utility model: the material of the adsorption layer is activated carbon, and the activated carbon is convenient for absorbing the odor of the liquid flowing out of the wound.

[0016] Beneficial effects of the utility model:

[0017] 1. Through the arrangement of the expansion component, the protective strip and the extension component, when in use, after the hydrocolloid dressing is pasted on the wound, the protective paper is peeled off and the elastic cellulose cloth layer is fixed on the skin. When the wound exudes fluid, the absorption layer and the absorbent foam layer absorb the fluid, which will cause the hydrocolloid dressing to expand. A gap is left inside the placement groove for the absorbent foam layer to expand and extend. When there is too much exudate and the absorbent foam layer reaches the inner wall of the expansion box, the absorbent cotton thread absorbs the absorbent foam layer, thereby achieving the extension effect, avoiding the instantaneous excessive fluid discharge from the wound, causing part of the fluid to diffuse out before being absorbed, and preventing the dressing from lifting up after the absorbed fluid expands, resulting in poor adhesion to the skin and falling off, thereby improving the use effect and service life of the hydrocolloid dressing and reducing the number of replacements and waste.

[0018] 2. Through the setting of waterproof layer, antibacterial component and adsorption layer, when using, the hydrocolloid dressing will inevitably come into contact with water and dust. The waterproof layer blocks the entry of external dust and water. The silver ion antibacterial layer can continuously release antibacterial ingredients to keep the skin surface clean and disinfected and reduce bacterial growth. The activated carbon in the adsorption layer can absorb the odor released by ulcers or necrotic tissue corruption during the wound recovery process, thereby achieving the antibacterial effect of the hydrocolloid dressing, avoiding bacterial growth during the wound recovery, and improving the antibacterial property of the hydrocolloid dressing and the timeliness of wound recovery.

The expansion component 5, the protective strip 10 and the extension component 12 are arranged to prevent the wound from leaking too much liquid instantly, so that part of the liquid diffuses out before being absorbed, and the dressing 3 is lifted up after the liquid is absorbed and expands, resulting in loose adhesion to the skin and falling off, thereby improving the use effect and service life of the hydrocolloid dressing, reducing the number of replacements and waste, and the surface of the extension component 12 is adhesively connected to the protective paper 13;

[0030] like Figure 5 As shown, the material of the water-absorbing foam layer 4 is polyurethane, and the water-absorbing foam layer 4 has the effect of moisturizing and absorbing;

[0031] like Figure 6As shown, the expansion component 5 includes an expansion box 501 fixedly connected to the inside of the groove, and the inner wall of the expansion box 501 is provided with a plurality of through holes, and the inside of the through holes is fixedly connected with a liquid-absorbing cotton thread 502. Through the arrangement of the expansion component 5, the exudate after the hydrocolloid dressing is expanded is absorbed, thereby improving the service life of the hydrocolloid dressing;

[0032] like Figure 3 As shown, the antibacterial component 8 includes a protective layer 801 fixedly connected to the surface of the adsorption layer 7, and a silver ion antibacterial layer 802 is fixedly connected inside the protective layer 801. The antibacterial component 8 has an antibacterial effect;

[0033] like Figure 2 As shown, the material of the protective strip 10 is sponge, and the setting of the protective strip 10 can prevent the leakage of the exudate;

[0034] like Figure 7 As shown, the extension component 12 includes an elastic cellulose cloth layer 1201 fixedly connected to the four sides of the waterproof layer 2, and a silicone gel layer 1202 is fixedly connected to the surface of the elastic cellulose cloth layer 1201.
