1. Medical non-woven fabrics are different from ordinary non-woven fabrics and composite non-woven fabrics. Ordinary non-woven fabrics have antibacterial properties; Composite non-woven fabric has good waterproof effect and poor air permeability. It is generally used for surgical clothes, surgical sheets, etc; Medical non-woven fabrics are pressed by spunbonded, melt blown and spunbonded (SMS) processes. They have the characteristics of antibacterial, hydrophobic, breathable and lint free. They are used for the final packaging of sterilized articles without one-time 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 meet the specification requirements of GB/T19633 and YY/T0698.2 at the same time.
3. Non woven fabrics are valid for use. The validity period of medical non-woven fabric is usually 2 ~ 3 years. The validity period of products from different manufacturers is slightly different. Please refer to the instructions. Aseptic articles packaged with medical non-woven fabrics are valid for 180 days, which is better not affected by sterilization methods.
4. The non-woven fabric used for the packaging of sterilized articles should be 50g / m2 plus or minus 5g.
5. When the closed packaging method is adopted for medical non-woven surgical instruments, two layers of non-woven fabrics shall be packaged in two times. Repeated folding forms a long bending path to prevent microorganisms from easily entering the sterilization package. Two layers of non-woven fabrics cannot be packaged at one time.
6. After high-temperature sterilization, the internal results of medical non-woven fabrics change, affecting the penetration and antibacterial properties of sterilization media. Therefore, medical non-woven fabrics shall not be sterilized repeatedly.
7. Due to the waterproof performance of non-woven fabrics, too many and heavy metal appliances are sterilized at high temperature, forming condensate in the cooling process, which is easy to produce wet bags. Therefore, the water absorbing material shall be paved in the larger appliance bag, the loading capacity of the sterilizer shall be appropriately reduced, the gap shall be reserved between the sterilization bags, the drying time shall be appropriately extended, and the generation of wet bags shall be avoided as far as possible.
8. Special non-woven fabric shall be used for hydrogen peroxide low-temperature plasma. Medical non-woven fabrics containing plant fibers shall not be used. This is because plant fibers absorb hydrogen peroxide.
9. Medical non-woven fabric is not a medical device, but it relates to the sterilization quality of medical devices. The quality of medical non-woven fabrics as packaging materials and packaging methods are very important to ensure the sterility level.
10. Refer to the test report and batch test report provided by the manufacturer to test the physical and chemical properties of medical non-woven fabrics to ensure the quality of products. Medical non-woven fabrics are often used in hospitals, but they are also often used in daily life. Before using the medical non-woven fabric, you must check the shelf life and package damage, confirm that the medical non-woven fabric is not infected with bacteria, understand the problems that should be paid attention to when using the medical non-woven fabric in advance, and then ensure the use effect.
