Non-woven fabrics are widely used in medical treatment. Common masks, protective clothing, gloves, etc. The raw materials are non-woven fabrics. In addition to cotton packaging, non-woven packaging materials are commonly used in domestic disinfection supply centers. Cloth packaging, non-woven fabrics are a big step forward in reducing cotton dust pollution compared to cotton packaging.
The medical non-woven fabric is used to wrap the instrument box to prevent the sterilized instruments from being contaminated again. It is breathable, waterproof, flexible, non-toxic, non-irritating, etc., and can be used for sterilized packaging such as low-temperature plasma, pressure steam, and ethylene oxide.
So what are the quality requirements for medical non-woven fabrics?
1. Non-woven packaging materials should meet the requirements of "GB/T19663.1-2015 Packaging for Terminally Sterilized Medical Devices":
Microbial barrier, water resistance, compatibility with human tissues, air permeability, salt water resistance, surface absorption, toxicology test, maximum equivalent pore size, drape, tensile strength, wet tensile strength and burst resistance They are in compliance with relevant national regulations and should be used once.
2. Storage environment requirements
The storage requirements of medical non-woven fabrics meet the requirements of YY/T0698.2-2009.
That is, the temperature of the inspection, packaging and sterilization area is 20℃-23℃, the relative humidity is 30%-60%, and the mechanical ventilation is 10 times in 1 hour. The cotton dressing packing room must be separated from the equipment packing room to avoid cotton dust pollution of the equipment and Packaging materials such as woven fabrics.
3. Size requirements
①Instrument package in operating room:
Please refer to the size of the instrument cart in the operating room. If you need to use the non-woven fabric to pack the instrument cart surface, the size of the non-woven fabric must be greater than 30cm around the sagging instrument cart surface.
② Irregularly shaped devices:
For example, chest openers, electric drills, etc., choose a mesh basket to regularize them, and then use non-woven fabrics for packaging.
A round container such as a cotton ball cylinder is placed in the middle of the non-woven fabric, the left and right sides of the wrapping fabric are folded back, and then rolled forward. Fold the wrapping fabric 3cm-5cm inward and seal it.
③Frame hook type equipment:
Adhesive tape can be used to fix the non-woven fabric to prevent it from loosening.
4. Other requirements
①Requirements for sharp or hooked equipment
It is necessary to bring a sharp device protective cover to prevent such devices from piercing the non-woven fabric, causing device contamination and unnecessary waste of consumables.
②Requirements for overlapping items
Surgical basins, treatment bowls, etc. should be packaged separately as much as possible. If they need to be stacked, absorbent paper should be placed between the items to reduce the wet package rate.
③Requirements for small screws and drills
It is not advisable to directly use non-woven fabrics for packaging, and should be packed in precision instrument boxes with mesh holes before packaging.
