Description

Non-woven fabrics sterilization wrapping bag
Technical Field
The invention relates to the technical field of sterilization packaging, in particular to a non-woven fabric sterilization packaging bag.
Background
The medical sterilization packaging material has the function of forming a microorganism isolation barrier outside the medical instrument, so that the sterilized medical instrument is not polluted by external microorganisms within a certain period of time, and the medical instrument is relatively sterile before use; if the sterilization packaging material has poor microbial barrier function, the packaged medical apparatus is easily polluted by external pathogenic microorganisms after sterilization, the wound infection of a patient can be caused if the packaged medical apparatus is light, and the life of the patient can be threatened if the packaged medical apparatus is heavy, so that the reasonable selection and use of the medical sterilization packaging material are one of the most effective ways for controlling the hospital infection and ensuring the medical safety.
The medical sterilization packaging materials and appliances used in the medical field at present are mainly made of breathable and bacteria-resistant materials such as pure cotton woven cloth, paper-plastic packaging bags, Tyvek packaging bags, paper bags, plastic bags, medical non-woven fabrics, medical crepe paper and closed hard sterilization boxes, and have certain defects, wherein the pure cotton woven cloth has poor microbial barrier effect, is easy to damage, has a lot of cotton dust, has hidden troubles of particle pollution, has large workload of repeated cleaning and sterilization, and cannot be used for hydrogen peroxide plasma sterilization; the paper surface toughness, tear resistance and puncture resistance of the paper-plastic packaging bag are poor, and the paper is easy to be wet after pressure steam sterilization; the Tewei strong packaging bag has high cost and no high temperature resistance, is monopolized by large foreign companies all the time, belongs to one of the domestic 'neck' projects, and is only mainly used for hydrogen peroxide plasma sterilization at present; the paper bag has poor tear resistance, and the package contents cannot be seen; most of the medical non-woven fabrics are packaged in a closed wrapping mode, the instrument box is packaged twice by double-layer non-woven fabrics, and the instrument box needs to be tightly wrapped by a wrapping tape, so that the operation is time-consuming and labor-consuming; the medical crepe paper has poor toughness and tear resistance, high price and less adoption; the closed hard sterilization box is mainly used for pressure steam sterilization, is expensive, is easy to cause wet packaging, and is not easy to popularize and use.
