Abstract

The invention relates to plasma sterilizing indicating and discloses a plasma sterilizing indicator. The plasma sterilizing indicator at least one dye which can change color under the effect of hydrogen peroxide plasma and one pyridine derivative which plays a color fixation role in the indicator system. The plasma sterilizing indicator has the advantages that the plasma sterilizing indicator canhave evident color change before and after plasma sterilizing, the color after sterilizing cannot recover to the original color, excellent color stability is achieved, and whether a sterilizing targetis sterilized or not can be reliably judged; the introduction of the pyridine derivative can control the color changing speed of the dye in the hydrogen peroxide plasma, and accordingly whether the sterilizing conditions of the sterilizing target are appropriate or not can be judged according to color change.

Description

technical field [0001] This patent relates to the field of plasma sterilization indication, more specifically, to a plasma sterilization indicator, which can sterilize the sterilization target through the color change when the hydrogen peroxide low-temperature plasma sterilizes the sterilization target. Whether it has been processed by the sterilization process or whether it has been effectively sterilized is confirmed. Background technique [0002] With the rapid development of medical and health services and the continuous improvement of medical technology, various precision instruments and equipment are gradually popularized and applied, and these equipment generally cannot be sterilized by high temperature (mainly high temperature and high pressure steam, high temperature dry heat). In order to solve this problem, various low-temperature chemical sterilization methods have gradually emerged, such as ethylene oxide low-temperature sterilization used in hospitals in the 19...
