[0022] In the utility model, unless another definite provision and limitation, the terms "installation", "link", "connection", "fix" and so on terms should do broad sense understanding, for example, can be fixed connection, also can be detachable connection, or integration, can be direct connection, also can indirectly connect through the intermediate medium, can be the intercommunication of two elements or the interaction of two elements. For ordinary skilled person in the art, the specific meaning of the above-mentioned terms in the utility model can be understood according to specific circumstances.
[0023] In the description of this utility model, it should be understood that the terms "left", "right", "front", "rear", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0024] The present invention will be further described below with specific embodiments, but the scope of protection of the present invention is not limited to the following embodiments.
[0025] Implementation method 1: such as Figs. 1 to 4 As shown, this gynecological surgical wound dressing comprises, from bottom to top, an absorbent and moisturizing surface 1, a drying layer 2, an isolation surface 3, a release film 4, and a protective film 5. The absorbent and moisturizing surface 1 consists of two layers of non-woven fabric 11. Several rectangular, rounded-corner environmental control patches 12, designed to create a moist environment, are attached to the outer non-woven fabric. These environmental control patches 12 are arranged apart from each other, forming gaps for absorbing and removing exudate from the wound. In use: After unpacking, the adhesive edges of the release film are attached to the skin around the wound, allowing the absorbent and moisturizing surface to contact the wound. The inner non-woven fabric, utilizing the gaps between the environmental control patches, contacts the wound, absorbing and removing exudate. The environmental control patches, after absorbing moisture, form a hydrogel, maintaining a moist environment on the wound and accelerating wound healing.
[0026] Implementation Method 2: The environmental control patch 12 of this gynecological surgical wound dressing is a hydrogel patch. The isolation surface 3 includes three layers of medical gauze 31, with the inner medical gauze 31 adhered to the inner non-woven fabric 11 around its perimeter. The drying layer 2 is a layer of fiber drying particles filled between the inner medical gauze 31 and the inner non-woven fabric 11. The fiber drying particle layer undergoes secondary adsorption drying to ensure the dryness of the inner non-woven fabric, thereby enhancing the continuous absorption capacity of the outer non-woven fabric. When fully absorbed, the isolation surface, in conjunction with the vents on the release membrane, ensures wound ventilation while isolating bacterial invasion or foreign body contamination of the wound, preventing wound infection. The release membrane 4 is a PET film with numerous vents 41, and is laminated to the upper surface of the inner medical gauze 31. The protective patch 5 is a PE soft film, which can be peeled off and attached above the release membrane 4. When bathing or otherwise exposed to water, it prevents moisture from entering the wound. In other applications, the self-removing membrane can be peeled off to ensure breathability.
[0027] Implementation Method 3: The release film 4 of this gynecological surgical wound dressing extends outward from the edge of the isolation surface 3 to form an adhesive edge 42 around the skin. This edge is used to connect and fix the dressing to the skin around the wound.
[0028] The gynecological operation wound dressing patch is aimed at the wound surface environment characteristics required for gynecological wound healing, quickly pulls off the exudate and concentrates adsorption drying in the middle layer, provides a moist and clean wound surface environment for the wound, and under the premise of considering air permeability, performs rough surface isolation on the outside, effectively avoids bacterial invasion and causes wound infection.
