Dry heat sterilization indicating ink, preparation method and dry heat sterilization indicator

Abstract

The invention discloses dry heat sterilization indication ink, belonging to the field of chemical ink. The dry heat sterilization indication ink can accurately change color, realizes an indication function, does not fade after being stored for a long time at the same time, ensures the stability of sterilization indication, and comprises 15-25% by mass of a color change component and 30-70% by massof a binder. The preparation method for the dry heat sterilization indicating ink provided by the invention comprises the following steps: dissolving the binder in a diluent, then adding the discoloring component, carrying out full mixing, continuing adding a thickener and a defoamer, and carrying out uniform mixing and grinding so as to obtain the dry heat sterilization indicating ink. The invention discloses a dry heat sterilization indicator. The dry heat sterilization indicator comprises the dry heat sterilization indicating ink and a base material. The dry heat sterilization indicator provided by the invention has the following advantages: the ink does not fade; the indicating ink is not easy to fall off; and the functions of accurate color change and color fading prevention of the dry heat sterilization chemical indicator can be realized.

Description

technical field [0001] The invention relates to a dry heat sterilization indicator ink, a preparation method and a dry heat sterilization indicator, belonging to the field of chemical inks. Background technique [0002] Effective sterilization of medical kits is the key link to avoid postoperative infection of patients. As one of the commonly used sterilization methods in medical institutions or scientific research institutions, dry heat sterilization uses three methods of heat transfer (ie convection, conduction and radiation) to process the sterilized objects. In the process of dry heat sterilization, the bacteria on the sterilized items are mainly destroyed by increasing the temperature to cause non-specific oxidation of cell components. High temperature dry heat can cause thermal denaturation of microbial enzymes, damage to ribonucleic acid in cells and damage to cell membranes. injured and died. [0003] Most dry heat sterilization chemical indicators are divided into...

AI Technical Summary

Problems solved by technology

The operating room opens the package before the operation to further confirm whether the indicator card in the package is sterilized. If the indication is not up to standard, it can prompt that the dry heat sterilization effect of the package is unqualified, and the package cannot be used

[0004] If the color of the indicator label or indicator card fades after sterilization due to ink formula problems, it may lead to misjudgment by the sterilizer, and the secondary sterilization of the sterilized medical package will increase the sterilization cost of the medical package.
