AI Technical Summary

Technical Problem

In the prior art, hydrogen peroxide is easily decomposed in sterilization indicator resistance detectors, which leads to a decrease in the concentration in the detection chamber and affects the accuracy of the detection results.

Method used

The reaction chamber is separated by a baffle design, which separates the detection chamber and the preheating chamber. Gas containing sterilizing substances and dry gas are introduced through the first ventilation duct and the second ventilation duct, respectively. The heating device maintains their respective temperature ranges to ensure that the concentration of sterilizing substances in the detection chamber is stable.

Benefits of technology

It effectively maintained the concentration of sterilizing substances in the detection chamber, improving the accuracy and efficiency of sterilization indicator resistance detection.

Abstract

This invention discloses a sterilization indicator resistance detector, detection system, and detection method, applied in the field of resistance detection. The sterilization indicator resistance detector comprises a reaction chamber including a detection chamber and a preheating chamber, with a partition between the two chambers. The detection chamber has a first air inlet, a gas outlet, and a first sterilization indicator placement opening; the preheating chamber has a second air inlet and a second sterilization indicator placement opening. The partition has an opening. A first sterilization indicator placement area is provided in the detection chamber corresponding to the first sterilization indicator placement opening, and a second sterilization indicator placement area is provided in the preheating chamber corresponding to the second sterilization indicator placement opening. The first air inlet and gas outlet are correspondingly arranged. A heating device is used to heat the reaction chamber. This invention improves detection efficiency by directly introducing gas containing sterilizing substances into the detection chamber, stably maintaining the concentration of sterilizing substances within the detection chamber.
