Description

Vacuum packaging bag suitable for irradiation sterilization of medical protective clothing

Technical Field

The utility model belongs to the technical field of electron beam irradiation disinfection and sterilization of medical protective clothing product, concretely relates to vacuum packaging bag suitable for medical protective clothing irradiation sterilization.

Background

Compared with the traditional ethylene oxide sterilization process, the radiation sterilization has the advantages of environmental protection, no chemical gas emission, no ethylene oxide residue on a treated object, thorough sterilization, strong penetrating power, high sterilization speed, simple and convenient operation and the like. The ethylene oxide sterilization cycle of protective clothing is 7-14 days, whereas radiation sterilization can be accomplished within one day. The production period of the protective clothing can be greatly shortened by replacing ethylene oxide sterilization with irradiation sterilization, so that the urgent need of medical supplies in a special period is met.

However, since the protective clothing is mainly made of polymer fibers, free radicals are generated under high-energy rays, and the free radicals react with oxygen in the air and are converted into peroxide free radicals to initiate oxidative cleavage, so that the main chain is broken, low-molecular products are increased, and the performance of the protective clothing is obviously reduced. Therefore, a vacuum packaging bag is designed to reduce the contact of the protective clothing with oxygen after irradiation and irradiation so as to reduce the oxidative cracking of the protective clothing.

In addition, the penetration of the electron beam is lower than that of gamma rays, so that the requirement on the thickness of the irradiated sample is high. Conventional protective clothing products are sealed packages of plastic bags, and the packages contain a large amount of air, so that the thickness of the products is large.

Currently, no packaging product for protective clothing for electron beam sterilization is found. Traditional protective clothing wrapping bag is mainly made by polyethylene and polypropylene, and partly product passes through glue and seals, contains a large amount of air in the packing, is unfavorable for irradiation sterilization, and another part is sealed through the heat-seal method after the evacuation, can destroy the wrapping bag during the use, consequently, the packing can not used repeatedly.

In order to overcome the above defects, the vacuum packaging bag adopted in the market comprises a bag body with a bag opening and a one-way air suction port, and a sealing member (sealing tape) arranged at the bag opening. When the device is used, the sealing tape is opened, protective clothing is put into the sealing tape from the sealing tape, then the sealing tape is closed, the one-way air suction connector is vacuumized, and after the vacuumization is finished, the electronic accelerator is put into the device for irradiation sterilization.

However, the vacuum packaging bag has the following defects:

1. the effective period of the protective clothing after sterilization is generally 1 to 2 years, the protective clothing can be polluted by bacteria in the storage period, and the pollution condition of the protective clothing can not be found in time;

2. all protective clothing is stacked in a bag body, so that the effects of disinfection and sterilization by irradiation are poor, and the performance of the protective clothing is reduced.
