Wound Patch
Band aid is a medical device applied to the skin to cover wounds or incisions, in order to protect the wound from external contamination and irritation. It is made of breathable materials that can provide appropriate ventilation for wounds to promote wound healing. There are now many different types of wound dressings to choose from, including transparent, waterproof, antibacterial, and medication patches, among others. Outside the hospital, wound dressings are also one of the essential first aid supplies in the home first aid kit, which can be used for general injuries such as cutting and abrasions.
Product Definition

They create a relatively clean and dry healing environment for superficial wounds and skin injuries, prevent wound infection, and accelerate wound healing.
Performance structure and composition
Core structure: The adhesive tape is mainly composed of a water absorbing layer, a base band, and an isolation layer that come into contact with the wound. The water absorbing layer is usually a water absorbing pad used to absorb tissue fluid that seeps out of the wound; The base tape is generally made of elastic non-woven fabric or PE material, which has certain flexibility and breathability, can fit the skin, and fix the absorbent layer; The isolation layer is a non stick paper covering the water absorbing layer and the base tape, which can protect the water absorbing layer from contamination before use.
Raw materials: The water absorbing layer is mostly made of medical grade defatted cotton or highly absorbent fiber materials, which have good water absorption and retention properties; Common materials for baseband include non-woven fabric, PE film, etc., which are required to be non-toxic, non irritating, and have no allergic reactions to the skin; The isolation layer is usually coated with silicone anti adhesive paper to ensure that it can be easily peeled off during use and there will be no residue of adhesive on the band aid. Some adhesive bandages may also contain medicinal ingredients, such as Yunnan Baiyao adhesive bandages that contain Yunnan Baiyao powder, which has the effects of stopping bleeding and callus formation, reducing inflammation and swelling.
