Abstract

The utility model relates to a dry sterilization packaging bag, which comprises: the bag comprises a bag bottom, a bag surface and a closed cavity, wherein the corresponding part of the bag surface is mutually connected with the bag bottom; the bag bottom is made of a non-breathable material; the top of the bag surface is made of a breathable material, and the rest part of the bag surface is made of a non-breathable material; the middle lower part of the closed cavity is partitioned by a breathable material to form an object placing cavity positioned at the upper part of the dry sterilizing packaging bag and a dry cavity positioned at the lower part of the dry sterilizing packaging bag; and a drying agent is arranged in the drying cavity. Compared with the existing top bag, the drying and sterilizing packaging bag has the advantages that the drying agent can be separated from the part contacted with the ethylene oxide during sterilization, so that the moisture absorption performance of the drying agent cannot be influenced by the sterilization process of the ethylene oxide; after sterilization, the drying agent can ensure the drying environment in the packaging bag only by taking away the partition clip.

Description

Dry sterilization packaging bag

Technical Field

The utility model relates to the technical field of medical instrument packaging, in particular to a dry sterilization packaging bag.

Background

Ethylene oxide sterilization is one of the commonly used sterilization methods at present, and during the action of ethylene oxide, the ring structure of the ethylene oxide is broken, and the ethylene oxide and active groups such as amino, hydroxyl, carboxyl and the like on microbial protein are subjected to alkylation to replace unstable hydrogen atoms to form compounds with hydroxyethyl groups, so that the protein loses reaction groups required in basic metabolism, the metabolism of bacteria is damaged, the microbes are killed, and the purpose of sterilization is achieved.

In order not to affect the sterilization effect, the ethylene oxide sterilization needs to be carried out under a certain humidity to ensure the permeation and alkylation of the ethylene oxide. However, during long-term sterilization and desorption, humidification inevitably has a certain effect on the water content in the package, and the related properties of the product are also affected.

For products which are only suitable for ethylene oxide sterilization and need to be stored in a dry environment, the existing aluminum foil top bag cannot meet the requirement of ensuring the dry environment inside product packaging after sterilization, so that the product performance is influenced, and the effective period of the product is shortened.

The drying and sterilizing packaging bag provided by the utility model can ensure the ethylene oxide sterilizing effect of the product, can absorb redundant moisture in the packaging bag by using the drying agent in the packaging bag after sterilization and resolution, ensures the drying environment of the product, and is convenient to operate.
