Medical non-woven fabric materials, with the continuous update and rapid development of sterilized items packaging materials, medical non-woven fabrics, as the final packaging materials for sterilized items, have successively entered the disinfection supply centers of various hospitals at all levels.
1. Medical non-woven fabric is different from ordinary non-woven fabric and composite non-woven fabric. Ordinary non-woven fabric does not have bacteria resistance; composite non-woven fabric has good waterproof effect and poor air permeability, and is generally used for surgical gowns and surgical bed sheets; medical non-woven fabrics are made of spunbond, meltblown, and spunbond (SMS) processes It is made by pressing and has the characteristics of anti-bacterial, hydrophobic, air-permeable and no dander. It is used for the final packaging of sterilized items. It is disposable and requires no cleaning.
2. The quality standard requirements of medical non-woven fabrics: the medical non-woven fabrics used for the final packaging materials of sterilized medical devices should meet the specifications of GB/T19633 and YY/T0698.2.
3. The validity period of the non-woven fabric: the validity period of the medical non-woven fabric itself is generally 2 to 3 years. The validity period of the products of different manufacturers is slightly different, please refer to the instructions for use. Aseptic items packaged in medical non-woven fabrics should have an expiration date of 180 days and are not affected by the method of sterilization.
4. The non-woven fabric used for packaging sterilized items should be 50g/m2 plus or minus 5 grams.
5. When medical non-woven fabrics are used for packaging surgical instruments, a closed packaging method should be used. Two layers of non-woven fabrics should be packaged twice. Repeated folding can form a long curved path to prevent microorganisms from "easily" entering the sterilization package. Two layers of non-woven fabrics cannot be packaged once.
6. After high temperature sterilization of medical non-woven fabrics, the internal results will change, which will affect the penetration and antibacterial performance of the sterilization medium. Therefore, medical non-woven fabrics must not be sterilized repeatedly.
7. Due to the hydrophobic properties of non-woven fabrics, excessive and heavy metal instruments are sterilized by high temperature, and condensation water is formed during the cooling process, which is easy to produce wet packs. Therefore, pad water-absorbing materials in the large equipment package, appropriately reduce the loading capacity of the sterilizer, leave gaps between the sterilization packages, appropriately extend the drying time, and try to avoid generating wet packages.
8. "Tyvek" non-woven fabric should be used for hydrogen peroxide low-temperature plasma, and medical non-woven fabric containing plant fibers cannot be used, because plant fibers will absorb hydrogen peroxide.
9. Although medical non-woven fabrics are not medical devices, they are related to the sterilization quality of medical devices. The quality of medical non-woven fabrics as packaging materials and the packaging methods are essential to ensure the level of sterility.
