Description

A new type of medical sterilization packaging material

Technical Field

The utility model relates to the technical field of medical sterilization packaging materials, in particular to a new type of medical sterilization packaging material.

Background Art

Commonly used medical sterilization packaging materials include cotton cloth, disposable non-woven fabric, crepe paper, hard containers and paper/plastic packaging bags. Among them, pure cotton textile fabrics have defects such as poor microbial barrier function, large cotton fiber pollution and easy wet packaging; paper/plastic packaging bags have defects such as poor moisture resistance and are only suitable for packaging small medical devices; medical non-woven fabrics and medical crepe paper have defects such as poor packaging sealing performance and high consumption, while sealed hard sterilization boxes have defects such as high purchase and maintenance costs and are not easy to popularize.

The commonly used sterilization method in hospitals is mainly high-pressure steam sterilization. After the medical devices are packaged with wrapping materials, they can be directly sterilized with high-pressure steam. This method is safe, environmentally friendly and fast. At present, the commonly used sterilization packaging materials are crepe paper and composite non-woven fabrics. Crepe paper is easily punctured by sharp objects, causing the sterilization package to lose its bacterial isolation function, resulting in bacterial contamination of medical devices. Non-woven fabrics are composed of fibers, which have the advantages of moisture-proof and breathable, flexible, easy to decompose, non-toxic and non-irritating, and composite non-woven fabrics have strong anti-bacterial ability. SMS non-woven fabrics are composited by spunbond non-woven fabrics (S) and meltblown non-woven fabrics (M), and have strong resistance to hydrostatic pressure and tearing resistance. However, when SMS non-woven fabrics are used for direct packaging, SMS has no water absorption capacity, and water droplets are easily generated in the disinfection package. After the wet package, liquid channels are generated, which destroys the sterile environment in the disinfection package.
