With the continuous improvement of production enterprises represented by issuers in the field of medical non-woven fabric production technology, medical accessories are gradually being widely used, and the market size is rapidly increasing. Compared with traditional pure cotton woven fabrics, medical accessories have advantages such as high dust filtration, low postoperative infection rate, convenient disinfection and sterilization, and easy compounding with other materials.

What is foam polymer dressing for medical accessories?

This is a dressing made by foaming polymer materials (PU), and the surface is always covered with a semi permeable film, some of which have magnetic viscosity.

Advantages:

1. Rapid and powerful exudate absorption ability.

2. Low permeability, keeping the wound moist, and avoiding mechanical damage when changing dressings.

3. The barrier performance of the surface semi permeable film helps to prevent environmental particulate foreign objects such as dust and microbial invasion, and also helps to prevent cross infection.

4. Easy to use, good adaptability, suitable for all parts of the body

5. Insulation and cushioning against external impacts

Disadvantages:

1. Due to its strong absorption, it can affect the debridement process for low-permeability wounds

2. Relatively high costs.

3. Due to its opacity, it is inconvenient to observe the wound

It is mainly used to clean and cover wounds, absorb fluid in the body, provide a healing environment for wounds, and some medical dressings can also be used to support organs or tissues. At present, the common medical dressings on the market include medical skim gauze, medical skim cotton, band aids, etc. In recent years, with the development of technology in the field of medical dressings, chitosan dressings, biological dressings, foam dressings and other new materials and medical dressings with new functions emerge in endlessly.

The emergence of medical dressings has also brought new problems to the supervision of medical devices such as dressings. Some mechanical enterprises have unclear understanding of seasoning sauce and are unable to determine the management category of seasoning sauce, which troubles them. This article summarizes the classification rules of Xu Xu's medical dressings.

What is the situation where medical excipients are not managed according to medical devices?

(1) Medical dressings contain chemical components, traditional Chinese medicine, extracts, etc. The ingredients only exert pharmacological, immunological, or metabolic effects, with drugs playing a major role. A clean covering of the wound does not absorb fluid from the body, providing a healing environment for the wound.

For example, the traditional adhesive for treating dampness is mainly made of medical pressure-sensitive adhesive and natural edible turtle leaf grass, which are coated on a medical non-woven fabric substrate. The surface is covered with a protective film and polyethylene polymer material. Used for pain caused by bone injury sequelae and osteoarthritis. The main function of natural edible Turtle Leaf Grass in the product is to alleviate pain, so medical devices are not used for management.

(2) Medical dressings not only have pharmacological, immunological, and metabolic effects, but also have the function of medical devices, with drugs playing a major role.

For example, povidone iodine wound dressings contain the antibacterial drug povidone iodine, which mainly protects the wound from contamination through the pharmacological effects of povidone iodine. Therefore, medical devices are not used for management.
