Hemostatic patch, also known as benzalkonium chloride patch, is commonly known as bactericidal elastic band-aid for simple treatment after minor trauma. Simple and convenient to use. If used reasonably, it does bring many benefits to the treatment of minor wounds, relieve pain and promote wound healing.
Because of the limited structure, the band-aid can only be used for emergency treatment of small wounds, which can temporarily stop bleeding and protect the wounds. However, it should be noted that the use time should not be too long. If used for a long time, the adhesive tape on the outer layer of the band-aid will be airtight, which will make the wound and the skin around the wound white and soft.
