Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical dressing technology, and in particular to an anti-adhesion dressing for hemorrhoid wounds. Background Technology
[0002] Hemorrhoid wound anti-adhesion dressing is a medical dressing used for wound protection after anorectal surgery. Its main function is to cover the wound at the anus after surgery, absorb exudate, prevent tissue adhesion, and provide a moist and supportive environment for wound healing. It is suitable for local wound repair after excision of internal hemorrhoids, external hemorrhoids, and mixed hemorrhoids.
[0003] The anal area has a complex structure, and the postoperative wound is deep and easily affected by tension, friction and excrement. The wound surface is very prone to forming poor adhesions. Using anti-adhesion dressings can effectively isolate the wound edge tissues, reduce the incidence of postoperative complications, reduce the patient's pain and postoperative recovery burden, and is an important auxiliary means to improve surgical efficacy and shorten the recovery period.
[0004] Ordinary anti-adhesion dressings have problems with unstable fixation and uncontrollable deformation in postoperative applications. The special location of the wound makes it difficult for the dressing to adhere firmly. After absorbing liquid, the expansion can easily cause lateral pressure, affecting wound closure and inducing the risk of dislodgement. In the existing technology, biodegradable sponge dressings are used to absorb postoperative exudate and maintain a moist environment in the wound. At the same time, a supporting skeleton structure is added to improve the support and improve stability. However, in actual use, the direction of expansion of the dressing after absorbing water is still uncontrollable, making it difficult to keep it in the center of the wound. It may push open the anal margin, causing secondary trauma or tissue re-adhesion, affecting the recovery effect. Utility Model Content

[0043] Working principle: In use, first open the opening plate 601 of the opening mechanism 6 to expose the adhesive surface 501 of the contact mechanism 5 through the opening 602, completing the preparation work before dressing use. Then, invert the entire dressing so that the drug mechanism 4 faces upward. At this time, the antibacterial and hemostatic drug solution stored in the drug solution tank 402 of the drug solution storage layer 401 in the drug mechanism 4 is fully absorbed by the absorbent sponge column 4052 through the absorbent guide hole 4051 of the absorbent component 405 under the action of gravity and conducted to the expansion plate 304 of the directional expansion mechanism 3. After the expansion plate 304 absorbs the drug solution, it achieves unidirectional controllable expansion in the vertical direction through the unidirectional expansion hole 305 at the top. The elastic directional skeleton 301, the connecting buckle 302 and the connecting adhesive 303 work together to maintain the stability and flexibility of the expansion process and avoid the expansion from generating lateral pressure on the wound. The adhesive surface 501 of the contact mechanism 5 is precisely applied to the hemorrhoid wound. The first adhesive patch 503 further enhances the contact stability. The breathable mesh 502 ensures a breathable environment in the wound area, providing good conditions for wound healing. The dressing is then firmly fixed to the perianal skin by the adhesive patch 801 and the second adhesive patch 802 of the fixing mechanism 8, ensuring that the dressing will not shift during use. The isolation ring 701 and the degradable gel edge 702 of the anti-permeability mechanism 7 play a role in preventing external liquids from entering and strictly controlling the release of medication along the set path. The adhesive surface 6031 of the adhesive patch assembly 603 stably adheres to the opening patch 601. After the operation, the degradable gel 6032 automatically softens and degrades, making it easy to remove the dressing painlessly. This completes the functions of the dressing in preventing adhesion and protecting the hemorrhoid wound, continuously supplying medication, maintaining the wound environment, and facilitating easy removal.
