1. Medical non-woven fabric is different from ordinary non-woven fabric and composite non-woven fabric. Ordinary non-woven fabrics do not have bacteriostatic properties; composite non-woven fabrics have good waterproof effect and poor air permeability, and are generally used in surgical gowns and surgical sheets; medical non-woven fabrics adopt the process of spunbond, meltblown, spunbond (SMS) Compressed and formed, it has the characteristics of antibacterial, hydrophobic, breathable, and dandruff-free. It is used for the final packaging of sterilized items.

2. Quality standard requirements for medical non-woven fabrics: The medical non-woven fabrics used for the final packaging materials of sterilized medical devices should meet the requirements of GB/T19633 and YY/T0698.2.

3. The non-woven fabric is valid for use: the validity period of the medical non-woven fabric itself is generally 2 to 3 years, the product of different manufacturers is slightly different, please refer to the instructions for use. Sterile items packaged with medical non-woven fabrics should be valid for 180 days and are not affected by sterilization methods.

4. The non-woven fabric used for packaging sterilized items should be 50g/m2 plus or minus 5g.

5. When packaging surgical instruments with medical non-woven fabrics, the closed packaging method should be used. The two layers of non-woven fabrics should be packed twice, and repeated folding can form a long curved path to prevent microorganisms from "easy" entering the sterilization package. Do not pack 2 layers of non-woven fabrics at a time.

6. Medical non-woven fabrics undergo high-temperature sterilization, and their internal results will change, affecting the penetration and sterilization performance of the sterilization medium. Therefore, medical non-woven fabrics must not be repeatedly sterilized.

7. Due to the hydrophobic properties of non-woven fabrics, excessive and heavy metal instruments are sterilized at high temperature, and condensed water is formed during the cooling process, which is easy to produce wet packs. Therefore, padding water-absorbing materials in the large equipment bag, appropriately reducing the loading capacity of the sterilizer, leaving gaps between the sterilization bags, prolonging the drying time appropriately, and avoiding the generation of wet packs as much as possible.

8. Hydrogen peroxide low temperature plasma cannot use medical non-woven fabrics containing plant fibers, because plant fibers will absorb hydrogen peroxide.

9. Although medical non-woven fabric is not a medical device, it is related to the quality of medical device sterilization. The quality of medical non-woven fabric as a packaging material and the packaging method are very important to ensure the sterility level.

10. Refer to the inspection report and product batch inspection report provided by the manufacturer, and check the physical and chemical properties of medical non-woven fabrics to ensure that the quality of the products used is qualified.

For the management of medical non-woven fabrics, the manufacturer is responsible for the production quality of medical non-woven fabrics, the hospital equipment department and the infection office are responsible for product qualification review and quality acceptance, and the supply room personnel are responsible for the packaging quality of sterilized items. Can guarantee the sterilization quality of medical devices.
