What are the issues that need to be paid attention to in medical acupuncture non-woven fabrics?

Update:18 Jan 2022
With the continuous update and rapid development of packaging materials for sterilized items, medical acupuncture non-woven fabrics have gradually entered the disinfection supply centers of various types of hospitals as the final packaging materials for sterilized items. How to control the quality of medical acupuncture non-woven fabrics, you must pay attention to these ten aspects of medical acupuncture non-woven fabrics.





​​
1. Medical acupuncture non-woven fabrics are different from ordinary acupuncture non-woven fabrics and composite acupuncture non-woven fabrics. Ordinary acupuncture non-woven fabrics do not have antibacterial properties; composite acupuncture non-woven fabrics have good waterproof effect and poor air permeability, and are generally used for surgical gowns and surgical sheets; medical acupuncture non-woven fabrics are made of spunbond, meltblown, spun The adhesive (SMS) process is pressed together, and has the characteristics of antibacterial, hydrophobic, breathable, and no lint. It is used for the final packaging of sterilized items, and is one-time use without cleaning.
​​
2. Quality standard requirements for medical acupuncture non-woven fabrics: Medical acupuncture 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.
​​
3. The validity period of acupuncture non-woven fabrics: the validity period of medical acupuncture 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 acupuncture non-woven fabrics should have a validity period of 180 days and will not be affected by the sterilization method.
​​
4. The needle-punched non-woven fabric used for packaging sterilized items should be 50g/m2 plus or minus 5 grams.
​​
5. When packaging surgical instruments with medical acupuncture non-woven fabrics, the closed packaging method should be adopted. Two layers of acupuncture non-woven fabrics should be packaged in 2 times. Repeated folding can form a long curved path to prevent microorganisms from "easily" entering the sterilization device. In the bacterial bag, 2 layers of acupuncture non-woven fabric cannot be used for one packaging.
​​
6. Medical acupuncture non-woven fabrics are sterilized at high temperature, and their internal results will change, which will affect the penetration and antibacterial properties of the sterilization medium. Therefore, medical acupuncture non-woven fabrics should not be repeatedly sterilized for use.
​​
7. Due to the hydrophobic properties of needle-punched 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.
​​
8. "Tyvek" acupuncture non-woven fabrics should be selected for low-temperature plasma of hydrogen peroxide, and medical acupuncture non-woven fabrics containing plant fibers cannot be used, because plant fibers will absorb hydrogen peroxide.
​​
9. Although the medical acupuncture non-woven fabric is not a medical device, it is related to the sterilization quality of the medical device. The quality of the medical acupuncture non-woven fabric as a packaging material and the packaging method are very important to ensure the sterility level.
​​
10. Refer to the inspection report and product batch inspection report provided by the manufacturer that meet the requirements, and check the physical and chemical properties of the medical acupuncture non-woven fabric to ensure the quality of the products used.
