Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wound dressings, in particular to a disposable postoperative wound dressing. Background Art
[0002] Postoperative wounds, also known as surgical wounds or procedural wounds, are caused by intentional medical procedures performed to treat existing diseases. Postoperative wounds are characterized by rupture of the skin layer. Postoperative wound care varies depending on the type of wound. For wounds closed by simple suturing (primary healing), the wound is covered with a protective dressing and the sutures or staples are removed after a certain number of days. For sutureless wounds (secondary healing), after removing dead skin or non-nervated tissue, a dressing that promotes wound healing in a moist environment should be used, and the dressing should be changed regularly under optimal aseptic conditions.
[0003] For sutured postoperative wounds, care should be taken to maintain cleanliness, disinfect the wound regularly, change the dressing regularly, avoid hot and humid environments, wear comfortable clothing, and avoid tight clothing that compresses the wound. Carefully observe the wound healing process, and seek medical attention promptly if any abnormalities (such as bleeding, fever, or increased pain) are found. Currently, dressings used for postoperative wounds are typically disposable self-adhesive dressings that are applied to the wound. These traditional dressings have the following drawbacks:
[0004] (1) The existing dressing is flat. After it is applied, even if the patient wears very loose clothes, the clothes will inevitably come into contact with the dressing, which will have a certain impact on the air permeability of the dressing;
[0005] (2) Existing dressings are usually relatively thin to ensure breathability. If the wound bleeds, the blood can easily penetrate the dressing and stain the clothing, causing clothing contamination;
[0006] (3) After absorbing the pus, blood and body fluids discharged from the wound, the core of the existing dressing becomes less breathable and cannot keep the wound surface dry, thus affecting wound healing. Utility Model Content
[0007] In order to solve the deficiencies of existing dressings, the utility model provides a disposable postoperative wound dressing.
[0008] The technical solutions adopted in this utility model are as follows:
[0009] A disposable postoperative wound dressing comprises a substrate layer, a core and a raised portion, wherein the raised portion is arranged on the top of the substrate layer and has a hollow hole, the core is arranged at the bottom of the substrate layer and corresponds to the raised portion, the core is composed of a plurality of spherical cores arranged in an array, and there is a breathable hole between two adjacent spherical cores, and an adhesive surface is provided at the bottom of the substrate layer, and the adhesive surface surrounds the core.
[0010] As a preferred embodiment of the present invention, the raised portion is a curved structure, so that the outer surface of the dressing forms a streamlined structure.
[0011] As a preferred embodiment of the present invention, the coverage area of the raised portion is larger than the coverage area of the core, thereby further preventing blood oozing from the wound from staining clothing.
[0012] As a preferred embodiment of the present invention, the raised portion is made of flexible material and is bonded to the top center position of the substrate layer; the raised portion is made of silicone material; the silicone material has a certain softness, and the raised portion composed of silicone material can produce a certain deformation depending on the different adhesion locations of the dressing piece.
[0013] As a preferred embodiment of the present invention, the substrate layer is made of medical non-woven fabric; the adhesive surface is made of medical pressure-sensitive adhesive; in order to ensure the cleanliness and integrity of the adhesive surface before use, a release film is provided on the adhesive surface.
[0014] As a preferred embodiment of the present invention, the spherical core adopts activated carbon fiber dressing; activated carbon fiber dressing has a strong ability to adsorb bacteria, and can quickly absorb a large amount of pus, blood, body fluids, bacteria and early inflammatory cytokines discharged from the wound, keep the wound surface dry and clean, and promote wound healing.
[0015] The utility model is beneficial in that:
[0016] (1) It has a raised portion, which forms a certain cavity between the dressing and the clothing, ensuring the air flow and breathability around the dressing. At the same time, it avoids direct contact between the clothing and the dressing, preventing blood oozing from the wound from penetrating the dressing and staining the clothing;
[0017] (2) The core of the compress is composed of a plurality of spherical cores arranged in an array, and there are air holes between the spherical cores, so that the core can still maintain a certain degree of air permeability after absorbing the pus, blood and body fluids discharged from the wound, so as to keep the wound surface dry and clean and promote wound healing.
