<p>With the continuous update and rapid development of the packaging materials for sterilized articles, medical non woven fabrics as the final packaging materials for sterilized articles have successively entered the disinfection supply centers of all levels and types of hospitals. How to control the quality of medical <a href="https://www.synwinchina.com/non-woven-products" rel="noopener noreferrer" target="_blank"><strong>non woven fabrics</strong></a>, you must pay attention to the ten aspects of medical non woven fabrics.</p><p><br></p><p>Ten key points of medical non woven fabrics</p><p><br></p><p>1. Medical non woven fabrics are different from ordinary non woven fabrics and composite non woven fabrics. Ordinary non woven fabrics have no resistance to bacteria; Composite non woven fabric has good waterproof function and poor air permeability. It is generally used for operating clothes and bed sheets. Medical non-woven cloth is made by the process of spunbonded, melt-sprayed and SPunbonded (SMS). It has the characteristics of anti-bacteria, hydrophobic, breathable and no dander. It is used for the final packaging of sterilized articles.</p><p><br></p><p>2. Quality standard requirements for medical non woven fabrics: Medical non woven fabrics used for final packaging materials of sterilized medical devices shall meet both GB/T19633 and YY/T0698.2.</p><p><br></p><p>3. non woven fabrics are valid for use: medical non woven fabrics are usually valid for 2 to 3 years. The validity of products from different manufacturers is slightly different, please refer to the instructions. Sterile articles packed with medical non woven fabrics should be valid for 180d and not affected by the sterilization method.</p><p><br></p><p>4. It is advisable to add or subtract 5 grams from 50g/m2 of non-woven cloth for sterilizing articles.</p><p><br></p><p>5. When packaging surgical instruments with medical non-woven cloth, the method of closed packaging should be adopted. Two layers of non-woven cloth should be packaged in two times, which can be folded repeatedly to form a long bending path, so as to prevent microorganisms from "easily" entering the sterilization bag.</p><p><br></p><p>6. After high temperature sterilization, the internal results of medical non woven fabrics will change, which will affect the penetration and anti-bacteria performance of the sterilization medium. Therefore, medical non woven fabrics shall not be used for repeated sterilization.</p><p><br></p><p>7. Due to the hydrophobic property of non woven fabrics, excessive and heavy metal instruments are sterilized at high temperature. Condensation water is formed during cooling process, which is easy to produce wet bags. Therefore, absorbent material should be placed in the big instrument bag, the load of sterilizer should be reduced appropriately, space should be left between sterilizing bag, drying time should be extended appropriately, and wet bag should be avoided as far as possible.</p><p><br></p><p>8. Hydrogen peroxide low-temperature plasma should be selected from "Twostrong" non woven fabrics, not medical non woven fabrics containing plant fibers, because plant fibers will absorb hydrogen peroxide.</p><p><br></p><p>9. 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 the packaging method are crucial to ensure the level of sterility.</p><p><br></p><p>10. Check and accept the physical and chemical properties of medical non woven fabrics according to the inspection report and batch inspection report provided by the manufacturer to ensure the quality of the used products.</p><p><br></p><p>For the management of medical non woven fabrics, the non-woven manufacturers are responsible for the production quality of medical non woven fabrics, the hospital equipment Department and infection Office are responsible for the qualification examination and quality acceptance of products, and the supply room personnel are responsible for the packaging quality of sterilized articles. The sterilization quality of medical devices can be guaranteed only when the four pipes are combined.</p>
