Due to its excellent performance, medical non-woven fabrics are increasingly used as packaging materials for sterilization articles in hospital disinfection supply centers. As the quality of medical supplies non-woven fabrics directly related to the patient's life safety, as a professional non-woven fabric manufacturer, please share the precautions in the use of medical non-woven fabrics.
1. Medical nonwovens are 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, and has the characteristics of bacteriostatic, hydrophobic, ventilating and no dandruff. It is used for sterilized packaging without cleaning.
2. Quality standard requirements for medical non-woven fabrics: Medical non-woven fabrics used for sterilization of medical device packaging materials shall meet the requirements of GB/T19633 and YY/T0698.2.
3, the period of validity of non-woven fabrics: the validity period of medical non-woven fabrics is generally 2 to 3 years, the product validity period 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. It is advisable to add or subtract 5 grams of non-woven fabric for sterilization of 50g/m2.
5, when the medical non-woven packaging surgical instruments, the closed packaging method should be divided into two layers of non-woven fabrics, and repeated folding can form a long curved path to prevent microorganisms from "easy" into the sterilization package. Can not be packaged in 2 layers of non-woven fabric.
6. After the medical non-woven fabric is sterilized by high temperature, the internal results will change, which will affect the penetration and sterilization performance of the sterilization medium. Therefore, the medical non-woven fabric shall 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. Low-temperature plasma of hydrogen peroxide should use special non-woven fabric. Medical nonwoven fabric containing plant fiber can not be used, 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 inspection report and product batch test report provided by the manufacturer, and check the physical and chemical properties of the medical non-woven fabric to ensure the quality of the used product.
The above is the precautions in the use of medical non-woven fabrics. I hope everyone can buy non-woven products with excellent quality.
