What do you need to know about medical non-woven fabrics?
Medical non-woven fabrics are laminated using spunbond, meltblown, and spunbond (SMS) processes. They have the characteristics of antibacterial, hydrophobic, breathable, and lint-free. They are used for packaging sterilized items and are used for one-time use. Clean.
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 medical non-woven fabric has good waterproof effect and poor air permeability, and is generally used for surgical gowns and surgical bed sheets;
2. Quality standard requirements for medical non-woven fabrics: medical non-woven fabrics used for sterilizing medical device packaging materials should meet the specifications of GB/T19633 and YY/T0698.2.
3. The validity period of the medical non-woven fabric itself is generally 2 to 3 years. The validity period of products from different manufacturers is slightly different, please refer to the instructions for use. The sterile 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 medical 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 to package 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. 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 packaging methods are essential to ensure sterility.
9. Refer to the inspection report and product batch inspection report provided by the manufacturer, and check the physical and chemical properties of the medical non-woven fabric to ensure the quality of the products used.
