The quality of medical non-woven fabrics is very important. How to grasp the quality of medical nonwoven fabrics, Laichi will give you a stroke today.

1. Medical nonwoven fabrics are different from ordinary nonwoven 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 air permeability, and are generally used in surgical gowns and surgical sheets; medical nonwoven fabrics are spunbond, meltblown, and spunbond (SMS) processes. It is formed by pressing and has the characteristics of antibacterial, hydrophobic, breathable, and no lint. It is used for the final packaging of sterilized items. It is one-time use and does not need to be cleaned.

2. After high-temperature sterilization of medical nonwoven fabrics, the internal results will change, which will affect the penetration and antibacterial properties of the sterilization medium. Therefore, medical non-woven fabrics should not be repeatedly sterilized for use.

3. Quality standard requirements for medical non-woven fabrics: Medical non-woven fabrics used for final packaging materials of sterilized medical devices should meet the requirements of GB/T19633 and YY/T0698.2 at the same time.

4. When packaging surgical instruments with medical nonwoven fabrics, the closed packaging method should be used. Two layers of non-woven fabrics should be packaged in two times. Repeated folding can form a long curved path to prevent microorganisms from "easily" entering the sterilization package. 2 layers of non-woven fabrics cannot be used for 1 packaging.

5. Due to the hydrophobic properties of non-woven fabrics, excessive and heavy metal instruments are sterilized at high temperature, and condensed water is formed during the cooling process, which is prone to wet packs. Therefore, pad water-absorbing material in the large instrument bag, appropriately reduce the loading capacity of the sterilizer, leave a gap between the sterilization bags, and appropriately prolong the drying time, so as to avoid the generation of wet bags as much as possible.

6. "Tyvek" non-woven fabrics should be used for low-temperature plasma of hydrogen peroxide, and medical non-woven fabrics containing plant fibers cannot be used, because plant fibers will absorb hydrogen peroxide.

7. The validity period of non-woven fabrics: the validity period of medical non-woven fabrics is generally 2 to 3 years, and the validity period of products of different manufacturers is slightly different, please refer to the instructions for use. Sterile articles packaged with medical non-woven fabrics should have a validity period of 180 days and will not be affected by sterilization methods.

8. Although medical non-woven fabrics are not medical devices, they are related to the sterilization quality of medical devices. The quality of medical nonwoven fabrics as packaging materials and the packaging method are very important to ensure the sterility level.
