What is medical non-woven fabric material?

What is medical non-woven fabric? Medical non-woven fabric materials, with the continuous updating and rapid development of the packaging materials of sterilized articles, medical non-woven fabrics as the final packaging materials for sterilized articles have successively entered the disinfection supply centers of various hospitals at all levels. Medical non-woven fabrics are different from ordinary non-woven fabrics and composite non-woven fabrics. Ordinary non-woven fabrics do not have bacterial resistance; Composite non-woven fabrics have good waterproof effect and poor air permeability, and are generally used for surgical gowns and surgical sheets; Medical non-woven fabrics are made of spunbond, melt spray, spunbond (SMS) The process of pressing is formed, which has the characteristics of blocking bacteria, hydrophobic, breathable and free of dandruff. It is used for final packaging of sterilized articles and is used once without cleaning. 2 Quality standard requirements for medical non-woven fabrics: medical non-woven fabrics used to sterilize the final packaging materials of medical devices shall comply with GB/T19633 and YY/T0698. 2 specification requirements. 3 Non-woven fabrics are valid for use: the validity period of medical non-woven fabrics is generally 2 ~ 3 years, the product validity period of different manufacturers is slightly different, please refer to the instructions. Sterile articles packed in medical non-woven fabrics should be valid for 180d and not affected by sterilization methods. 4 Non-woven fabrics used for packaging sterilized articles should be 50g/m2 plus or minus 5g. 5 when medical non-woven fabric packaging surgical instruments are used, the closed packaging method should be divided into 2 layers of non-woven fabrics, and repeated folding can form a long bending path, prevent microorganisms from entering the sterilization package 'easily' and cannot pack two layers of non-woven fabrics once. 6 Medical non-woven fabrics are sterilized at high temperature, and the internal results will change, affecting the penetration and resistance of the sterilization medium. Therefore, medical non-woven fabrics must not be sterilized repeatedly. Due to the hydrophobic properties of non-woven fabrics, excessive and excessive metal instruments are sterilized at high temperature, and condensed water is formed during cooling, which is easy to produce wet bags. Therefore, the absorbent material is placed in the large equipment bag, the loading capacity of the sterilizer 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 be made of 'strong' non-woven fabrics. Medical non-woven fabrics containing plant fibers cannot be used because plant fibers absorb hydrogen peroxide. Although medical non-woven fabrics do not belong to 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 level. 10 refer to the inspection report and product batch inspection report provided by the manufacturer, and check and accept the physical and chemical properties of medical non-woven fabrics to ensure the quality of the products used.
