With the updating and rapid development of packaging materials for sterilized items, medical non-woven fabrics as packaging materials for sterilized items have successively entered the disinfection supply centers of various hospitals at all levels.
The quality of medical non-woven fabrics has always been a concern for society. Below, medical non-woven fabric manufacturers will tell you ten common knowledge about medical non-woven fabrics.
1. Medical non-woven fabrics are different from ordinary non-woven fabrics and composite non-woven fabrics. Ordinary non-woven fabrics do not have antibacterial properties, while composite non-woven fabrics have good waterproof properties and poor breathability. They are generally used for surgical gowns and bed sheets; Medical non-woven fabric is pressed using a process of spunbond, melt blown, and spunbond (SMS). It has the characteristics of antibacterial, hydrophobic, breathable, and lint free. It is used for terminal packaging of sterilized items for one-time use without the need for cleaning.
2. Quality standards for medical non-woven fabrics: Medical non-woven fabrics used for sterilization of medical device terminal packaging materials should comply with both GB/T19633 and VY/T0698.2 specifications
accurate.
3. Non woven fabric has a shelf life: The shelf life of medical non-woven fabric itself is generally 2-3 years, and the shelf life of products from different manufacturers may vary slightly. Please refer to the instructions for use. Sterile items packaged with medical non-woven fabric have a shelf life of 180 days and are not affected by sterilization methods.
4. The non-woven fabric used for packaging sterilized items should be 50g/m2 plus or minus 5 grams.
5. When packaging surgical instruments with medical non-woven fabric, a closed packaging method should be used. Two layers of non-woven fabric should be packaged in two batches, and repeated folding can form a longer bending path to prevent microorganisms from easily entering the sterilization package. It is not allowed to package two layers of non-woven fabric once.
6. Medical non-woven fabrics undergo high-temperature sterilization, and their internal results will change, affecting the penetration and antibacterial properties of the sterilization medium. Therefore, medical non-woven fabrics cannot be reused for sterilization.
7. Due to the hydrophobic properties of non-woven fabrics, excessive and heavy metal instruments are sterilized at high temperatures, and condensation water is formed during the cooling process, which easily leads to the formation of bags. Therefore, the heat inside the Daqi City package.Absorbent materials, moderately reduce the loading capacity of sterilizers, leave gaps between sterilization bags, moderately increase drying time, and try to avoid the generation of wet bags as much as possible.
8. Hydrogen peroxide low-temperature plasma should use “Teweiqiang” non-woven fabric, and medical non-woven fabrics containing plant fibers cannot be used, as plant fibers will absorb hydrogen peroxide.
9. Although medical non-woven fabric does not belong to medical devices, it is related to the sterilization quality of medical devices. As a packaging material, the quality of medical non-woven fabric itself and the packaging method are particularly important to ensure the level of sterility.
10. Refer to the qualified inspection reports and product batch testing reports provided by the manufacturer, and inspect the physical and chemical properties of medical non-woven fabrics to ensure the quality of the products used is qualified.
