Background

With the continuous development of surgical instruments in recent years, the proportion of lumen instruments, complex structural instruments and various complex articles in the operation is higher and higher. When a medical institution uses an ethylene oxide sterilizer to sterilize instruments, particularly lumen instruments, complex structure instruments and various complex article packages, the existing monitoring means cannot simulate the structures of the lumen instruments, the complex structure instruments and the various complex article packages, so that the sterilization effects of the lumen instruments, the complex structure instruments and the various complex article packages cannot be simulated, and certain infection risks exist for the distribution of the instruments. The biological indicator generally needs to wait for more than 24 hours for the result to be displayed, so that the waiting is not beneficial to the rapid turnover of the instrument and the improvement of the working efficiency of the medical institution.

Disclosure of Invention

In order to solve the problems that the existing monitoring means can not simulate the sterilization effect of lumen instruments, complex structure instruments and various complex object packages and has certain infection risk for the distribution of the instruments, the invention provides the following technical scheme:

the utility model provides a five types of cards sterilization process verification device of ethylene oxide sterilization chemistry, comprises syringe, five types of chemical indicator cards of ethylene oxide, towel, the syringe constitute by cylinder, push rod, five types of chemical indicator cards of ethylene oxide set up in the cylinder, the syringe outside pass through towel parcel 2 layers, the towel wraps up through medical packaging bag outward.

Preferably, the syringe is a 20ml syringe with the needle removed.

Preferably, the towel is externally stuck to the closed package through an adhesive tape or an adhesive tape.

The invention has the advantages that:

1. the sterilization effect of the ethylene oxide sterilized article can be simulated really, and a basis is provided for the distribution of the sterilized article;

2. the challenge difficulty of sterilization is improved, and the challenge difficulty of the invention is difficult for all the sterilized article packages;

3. the challenge difficulty of the five types of chemical indicator cards is higher than that of a biological indicator under the same condition, and the monitoring level is further;

4. the user saves the time and the tedious work of manually manufacturing the chemical five-type card PCD sterilization process device.

5. The five chemical indicators have the advantage of visible monitoring results, the result output speed is high, long waiting is not needed, and the working efficiency is greatly improved.
