Water-based environment-friendly ethylene oxide sterilization indicating ink and preparation method thereof

Abstract

The invention relates to water-based environment-friendly ethylene oxide sterilization indicating ink and a preparation method thereof, and belongs to the technical field of medical sterilization. The water-based environment-friendly ethylene oxide sterilization indicating ink is prepared from the following raw materials in percentage by mass: 10 to 40 percent of binder, 0.1 to 1 percent of organic dye A, 0.1 to 1 percent of organic dye B, 5 to 10 percent of control agent and 30 to 80 percent of an alcohol aqueous solution. The water-based environment-friendly ethylene oxide sterilization indicating ink is a water-soluble system, has the advantages of being good in stability, low in VOCs emission, non-toxic, environmentally friendly and the like, can be visually interpreted when being applied to an indicator, and is high in accuracy, time-saving, efficient and wide in application field; the invention also provides a simple and feasible preparation method.

Description

technical field [0001] The invention relates to a water-based environment-friendly ethylene oxide sterilization indicator ink and a preparation method thereof, belonging to the technical field of medical sterilization. Background technique [0002] Sterilization of reusable medical devices is an important part of preventing patient infection. The current sterilization methods include high-temperature steam sterilization, hydrogen peroxide plasma sterilization, peracetic acid sterilization, low-temperature steam formaldehyde sterilization and ethylene oxide sterilization. Among them, ethylene oxide sterilization has the advantages of not damaging the sterilized items and has strong penetrating power, so most items that are not suitable for sterilization by other methods can be sterilized with ethylene oxide. [0003] According to the national regulations on the sterilization of medical devices, hospital medical staff are required to sterilize the corresponding chemical indic...

AI Technical Summary

Problems solved by technology

[0004] The ethylene oxide sterilization chemical indicator inks currently on the market mainly use the principle of acid-base reaction to cause the acid-base indicator to change color, and are easily affected by acid-base substances in paper and air, resulting in erroneous ethylene oxide sterilization chemical indicators. Discoloration, unable to monitor the ethylene oxide sterilization effect normally, increasing the unnecessary labor time of medical staff

In addition, the solvent-based ink system currently used is very unfriendly to the environment, and the emission of VOCs is huge, which is not environmentally friendly.
