Description

Technical Field

[0001] The utility model relates to the technical field of endoscope disinfection, in particular to a peracetic acid concentration monitoring device for endoscope disinfection. Background Technique

[0002] As a broad-spectrum, highly efficient and new environmentally friendly disinfectant, the commonly used concentration of peracetic acid disinfectant solution for endoscope disinfection is 0.2% - 0.35%. However, after multiple uses, the concentration will decrease. When the concentration is lower than 0.18%, the bactericidal ability will be greatly reduced. To ensure its bactericidal effect, it needs to be regularly detected during application. According to the Technical Standard Specification for Cleaning and Disinfection of Flexible Endoscopes (WS507-2016), it is required to record the monitoring results of the concentration and the amount of bacteria in the disinfectant during use.

[0003] Currently, the methods for monitoring the concentration of peracetic acid are all test papers, and the concentration is visually estimated through a color comparison card. This method is not accurate enough, and the recording method is even more backward. Some of the retained test papers will fade, and some will have reflections and color differences when photographed and uploaded to the information system. Most importantly, the above methods cannot truly reflect the concentration of the disinfectant solution and the accurate measurement time. Therefore, we provide a peracetic acid concentration monitoring device for endoscope disinfection. Summary of the Invention
