Device for detecting concentration of hydrogen peroxide in sterilizer in high-vacuum working state

Abstract

The invention discloses a device for detecting the concentration of hydrogen peroxide in a sterilizer in a high-vacuum working state. The device comprises a vacuum sterilizer cabinet body, a hydrogenperoxide concentration detection light-emitting unit, an initial hydrogen peroxide concentration detection light receiving unit, a hydrogen peroxide concentration detection light receiving unit, a hydrogen peroxide storage container, a filling pump, a flow meter, an electromagnetic valve and a control system. The invention provides a device for detecting the concentration of hydrogen peroxide in asterilizer in a high-vacuum working state. Simple structure and convenient use, the hydrogen peroxide concentration of the vacuum sterilizer cabinet body is detected in real time by adopting an ultraviolet spectrum; the hydrogen peroxide concentration detected in real time is compared and processed; when the detected concentration is lower than a certain value; and the filling pump, the flow meter and the electromagnetic valve are controlled to be opened to add hydrogen peroxide into the vacuum sterilizer, so that the concentration of hydrogen peroxide in the inner chamber of the sterilizer in a vacuum working state is ensured, and the risk caused by unqualified sterilization when the concentration of hydrogen peroxide is lower than the standard is effectively avoided.

Description

technical field [0001] The invention relates to the field of sterilization and disinfection products for medical instruments, in particular to a device for detecting the concentration of hydrogen peroxide in a high-vacuum working state in a sterilizer. Background technique [0002] At present, domestic similar products, that is, low-temperature plasma hydrogen peroxide sterilizers, do not have a device that can detect the concentration of hydrogen peroxide in the sterilization chamber under the state of sterilizing vacuum. Because the sterilization of this sterilizer mainly depends on a certain concentration (2.3㎎ / L±0.4) of hydrogen peroxide, at a certain temperature (50°C) and pressure (absolute pressure 80Pa), after a certain period of time to complete. [0003] Now it is by raising H every time 2 o 2 To control the concentration, it is impossible to truly detect the vacuum concentration in the sterilization chamber during sterilization. This will cause the sterilant H ...

AI Technical Summary

Problems solved by technology

[0003] Now it is by raising H every time 2 o 2 The amount to control the concentration, it is impossible to truly detect the vacuum concentration in the sterilization chamber during sterilization

This will cause the sterilant H 2 o 2 The concentration change will affect the sterilization quality, resulting in unqualified sterilization effect and serious consequences of cross-infection

[0004] In order to solve the above problems, it is urgent to invent a device for detecting the concentration of hydrogen peroxide in the high vacuum working state in the sterilizer, so as to solve the problem of real-time detection and control of the hydrogen peroxide concentration in the high vacuum working state of the sterilizer
