Medical dressing industry analysis

1. What is a medical dressing
Medical dressings refer to medical materials used to cover sores, wounds or other damages. Skin injury caused by wounds, burns, abscesses and ulcers will cause a series of problems in the body, such as bacterial infections, excessive loss of water and protein, endocrine and immune dysfunction, etc., which may be life-threatening.
Therefore, after skin injury, it is usually necessary to use skin substitute medical dressings to protect the wound, prevent wound infection and severe dehydration, provide a moist environment conducive to wound healing, and promote wound healing.
2. Classification of medical dressings
The British Royal School of Nursing 2005 Pressure Ulcer Guidelines divide dressings into five categories: contact dressings, active dressings, passive dressings, interactive dressings, and antibacterial dressings.
Contact dressings mainly include natural gauze and synthetic fiber dressings.
Active dressings mainly include: (1) Dressings containing active ingredients, such as dressings containing growth factors, collagen and hyaluronic acid; (2) Skin grafts, such as human or animal skin; (3) Tissue engineering products, Such as keratinocyte membranes, dermal substitutes.
Passive dressings, this type of dressing can create a local environment conducive to healing, but will not change the local physiological state or produce interaction. This kind of dressing is usually used to control exudation, prevent pollution or control odor. Such dressings include films, sponges and hydrogels.
Interactive dressings, this type of dressing changes the physiological state of the wound by contacting wound exudates, usually forming a gel-like covering on the wound surface to promote healing. Such dressings include hydrogels, alginates and hydrophilic fiber dressings.
Antibacterial dressings, such dressings contain certain antibacterial ingredients, such as silver, honey, iodine, chlorhexidine, etc., which have a certain local antibacterial effect.、
