Medical sterilization packaging bag

Abstract

The invention relates to a medical sterilization packaging bag which is formed by a closed cavity formed by connecting the corresponding parts of medical flexible sheet material; content is positioned inside the closed cavity; and the medical flexible sheet material at least comprises two pieces, wherein one piece is a transparent high-temperature-resistant medical composite plastic film, and the other one is medical non-woven. Every two opposite sides of the transparent high-temperature-resistant medical composite plastic film and the medical non-woven are connected with each other by hot melting or high-temperature-resistant bonding agent, so that the closed cavity can be manufactured. The medical non-woven is polypropylene fiber medical non-woven with three-layer structure, or terylene medical non-woven or polyurethane fiber medical non-woven. The medical sterilization packaging bag is provided with a sterilizing effect chemical indicating mark. By adopting the medical sterilization packaging bag, packed medical appliance can be sterilized by various conventional methods and can be maintained in a sterile state for a long time, so that the medical sterilization packaging bag has low cost and convenient use, and is beneficial to improve the sterile level of operation and all medical treatment operations.

Description

technical field [0001] The invention relates to a packaging bag, in particular to a medical sterilization packaging bag. Background technique [0002] The function of medical sterilization packaging materials is to form a microbial isolation barrier outside the medical device, so that the sterilized medical device will not be polluted by external microorganisms within a certain period of time, and ensure that the medical device is relatively sterile before use; Bacterial packaging materials have poor microbial barrier function, and the packaged medical devices are easily contaminated by external pathogenic microorganisms after sterilization, which can lead to wound infection of patients in mild cases, and endanger the lives of patients in severe cases. Therefore, reasonable selection and use of medical sterilization Packaging materials are one of the most effective ways to control hospital infection and ensure medical safety. In view of the importance of using medical steri...

Problems solved by technology

[0003] At present, the medical sterilization packaging materials and appliances used in the medical field mainly include pure cotton textile cloth, paper-plastic packaging bags, Tyvek packaging bags, paper bags, plastic bags, medical non-woven fabrics, medical crepe paper and airtight hard sterilization boxes. etc. These medical sterilization packaging materials and appliances all have certain defects, among which the pure cotton textile cloth has poor microbial barrier effect, has a lot of cotton dust, has hidden dangers of particle pollution, and cannot be used for hydrogen peroxide plasma sterilization; paper plastic The toughness, tear resistance and puncture resistance of packaging bags are poor, and they are easy to get wet after pressure steam sterilization; Tyvek packaging bags are expensive and not resistant to high temperatures, and are currently only used for hydrogen peroxide plasma sterilization; paper bags The tear resistance of plastic bags is poor, and the contents of the package cannot be seen; the sterilant penetration effect of plastic bags is poor; medical non-woven fabrics are mostly packaged, which cannot guarantee the preservation quality of sterilized instruments; the toughness and The tear resistance is poor; the closed hard sterilization box is mainly used for pressure steam sterilization, which is expensive and not easy to popularize.
