What is a medical nonwoven? Medical non-woven materials, with the continuous updating and rapid development of packaging materials for sterilized articles, medical non-woven fabrics as the final packaging materials for sterilized articles have gradually entered the disinfection supply centers of various hospitals at all levels.
1 .Medical nonwoven fabric is different from ordinary non-woven fabrics and composite non-woven fabrics Ordinary non-woven fabrics do not have antibacterial properties; composite non-woven fabrics have good waterproof effect and poor gas permeability, and are generally used for surgical gowns and surgical sheets; medical non-woven fabrics are spunbond, meltblown, and spunbond (SMS) processes. It is pressed and pressed, has the characteristics of bacteriostatic, hydrophobic, ventilating and no dandruff. It is used for the final packaging of sterilized articles, and it can be used once and without cleaning.
2 .Quality standards for medical non-woven fabrics: Medical non-woven fabrics used for sterilization of medical device final packaging materials shall meet the requirements of GB/T19633 and YY/T0698.2.
3 Non-woven fabrics are valid for use: The validity period of medical non-woven fabrics is generally 2 to 3. years. The expiration date of products of different manufacturers is slightly different. Please refer to the instructions for use. Sterile articles packaged in 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 the sterilized articles is preferably 50 g/m2 plus or minus 5 g.
5 .When the medical non-woven packaging surgical instruments are closed, the closed packaging method should be divided into two layers of non-woven fabrics. The repeated folding can form a long curved path to prevent microorganisms from “easy” entering the sterilization package. 2 layers of non-woven fabrics are packaged once.
6. Medical non-woven fabrics are sterilized by high temperature, the internal results will change, affecting the penetration and sterilization properties of the sterilization medium. Therefore, the medical non-woven fabrics must not be repeatedly used for sterilization.
7. Due to the hydrophobic properties of the non-woven fabric, excessive and excessively heavy metal instruments are sterilized by high temperature, and condensed water is formed during the cooling process, which tends to produce wet packets. Therefore, in the large equipment package, the water absorbing material is padded, the sterilizer load is appropriately reduced, the gap between the sterilization bags is left, the drying time is appropriately extended, and the wet bag is avoided as much as possible.
8 .Hydrogen peroxide low temperature plasma should use "Tween" non-woven fabric, can not use medical fiber containing plant fiber, because plant fiber will absorb hydrogen peroxide.
9 .Although medical non-woven fabrics are not medical devices, they are related to the quality of medical device sterilization. The quality of medical non-woven fabrics as packaging materials and the packaging methods are essential for ensuring the level of sterility.
10 .Refer to the manufacturer's inspection report and product batch test report, and check the physical and chemical properties of the medical non-woven fabric to ensure the quality of the product.
