Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wound dressings, in particular to a novel multi-layer composite wound dressing. Background Art
[0002] Band-aids are also called sterilizing elastic band-aids or benzalkonium chloride band-aids. They are mainly composed of long adhesive tape and protective composite pads. The adhesive tape is composed of elastic textile and adhesive plaster adhesive; the protective composite pad is composed of benzalkonium chloride, absorbent pad with strong absorbency and isolation permeable membrane. Band-aids stop bleeding by compressing and absorbing exudate to keep the wound dry, play a role of temporary hemostasis and protection of the wound surface, and are often used for emergency treatment of minor trauma or abrasions. Because of its convenient carrying and easy use, band-aids have become one of the most commonly used first aid essential medical supplies in hospitals, clinics, and families. Band-aids are mainly used for emergency treatment of neat, clean, superficial minor trauma and abrasions. This type of wound has a small exposed area of deep tissue and is not easy to scab. The pressure dressing of the band-aid is conducive to the closure, hemostasis and healing of the wound surface. The band-aid is composed of adhesive tape and protective composite pad; the adhesive tape is composed of elastic textile and adhesive plaster adhesive, which plays a role of compressing and stopping bleeding; the protective composite pad is composed of benzalkonium chloride, absorbent pad and isolation permeable membrane. Benzalkonium chloride is a cationic surfactant and a non-oxidizing bactericide with broad-spectrum and high-efficiency bactericidal ability. The absorbent pad can absorb exudate and keep the wound dry.

[0013] Furthermore, the isolation permeable membrane and the drug detection hole are interconnected, and the drug detection hole and the sealing patch are adhesively connected.
[0014] Compared with the prior art, the beneficial effects of the utility model are: this new multi-layer composite wound patch adopts a breathable structure, which can improve the comfort of the skin around the wound and effectively prevent skin discomfort. At the same time, the tear corner makes it convenient for users to quickly tear off the covering film.
[0015] 1. The utility model can ensure the flow of air around the user's wound skin through the breathable strip, so that the skin can breathe. The breathable strip will not damage the skin around the wound, which is beneficial to the local skin oxygen supply, effectively preventing the surrounding skin from sweating and reducing discomfort. The raised tearing angle makes it convenient for the user to tear off the covering film and improves the tearing efficiency. The release paper plays a role in protecting the absorbent pad during the manufacturing and transportation process, and it prevents the absorbent pad from accidentally adhering to other surfaces before application, thereby ensuring that the absorbent pad still has the best use effect when used.
