Medical nonwoven fabric is a kind of fabric that does not need to be spun. It is mainly bonded together by physical means directly, so when you stick it, you will find that you can not pull out the thread from the non-woven fabric. Medical non-woven cloth these ten problems you need to know.
1, medical nonwoven fabrics are different from ordinary non-woven fabrics and composite non-woven fabrics. Ordinary non-woven fabric does not have bactericidal; Compound non-woven cloth waterproof effect is good, poor air permeability, generally used for surgical clothes and surgical sheets; Medical nonwoven fabric is made of spunbonded, melt-blown, spunbonded (SMS) process, with antibacterial, hydrophobic, breathable, no dandruff characteristics, used for sterilization most final packaging, disposable use, without cleaning.
2. Quality standard requirements of medical non-woven fabric: Medical non-woven fabric used for most final packaging material of sterilized medical devices should meet the standard requirements of GB/T19633 and YY/T0698.2 at the same time.
3, non-woven fabric is the period of validity: the period of validity of medical non-woven fabric itself is generally 2~3 years, different manufacturers of product validity is slightly different, please refer to the instructions. Sterile articles packed with medical non-woven fabric should have a valid period of 180d and not be affected by sterilization methods.
4. It is advisable to add or subtract 5 grams of non-woven fabric 50g/m2 for the packaging of sterilized articles.
5. When medical non-woven fabric is used to pack surgical instruments, the method of closed packaging should be divided into two layers of non-woven cloth. Repeated folding can form a long bending path to prevent microorganisms from "easily" entering the sterilization bag, and two layers of non-woven cloth can not be packaged once.
6, Medical nonwoven fabric after high temperature sterilization, its internal results will change, affect the penetration of sterilization medium and antibacterial performance, therefore, medical non-woven cloth shall not be repeated sterilization use.
7, due to the hydrophobic performance of non-woven fabric, excessive and heavy metal instruments are sterilized at high temperature, and condensed water is formed in the cooling process, which is easy to produce wet packages. Therefore, water-absorbing materials should be placed inside the large instrument package, the loading capacity of the sterilizer should be appropriately reduced, space should be left between the sterilizer packages, and drying time should be appropriately extended to avoid wet packages as far as possible.
8, hydrogen peroxide low temperature plasma should choose "Tyvek" non-woven fabric, can not use medical non-woven fabric containing plant fiber, because plant fiber will absorb hydrogen peroxide.
9, although medical non-woven fabric does not belong to medical devices, but it is related to the sterilization quality of medical devices, medical non-woven fabric as a packaging material of its own quality, and packaging method is very important to ensure the asepsis level.
10. Check and accept the physical and chemical properties of medical non-woven fabric according to the inspection report and product batch test report provided by the manufacturer to ensure the quality of the used products.
