Abstract
The invention relates to a chemical indicator card for dry heat sterilization, belonging to the field of chemical indicators for dry heat sterilization. The chemical indicator card is characterized in that an indicator is coated on white card paper; the indicator comprises the following constituents in percentage by weight: 20-30% of resin, 5-10% of copper nitrate, 1-3% of tartaric acid, 50-60% of cyclohexanone and 10-20% of sodium carbonate, wherein the indicator is prepared by the steps of: mixing the resin with a solvent of the cyclohexanone, stirring until the resin is completely dissolved in the solvent, adding the copper nitrate and a reactant of the tartaric acid, adding a control agent of the sodium carbonate to stir for 1 hour, and grinding by using a three-roller grinder until the fineness measured by a scraper fineness gauge is less than 3 micros; and the indicator is coated on the white card paper by using a screen plate printing method. The chemical indicator card is simple and convenient to use and intuitive and accurate in result.
Description
Technical field
The present invention relates to a kind of dry heat sterilization chemical indicating card, belong to the chemical indicator field of dry sterilization.
Background technology
In the routine work of hospital, often there are various apparatuses, apparatus to sterilize and to sterilize.Along with people improve constantly the level of understanding of health, demand to various medical treatment product is more and more, these product needed are carried out strict sterilising treatment before use, sterilization process also relates to numerous areas such as medical treatment, medicine, food, sanitary product, therefore, the routine inspection and the quick identification of sterilising effect are had higher requirement.
Summary of the invention
The object of the present invention is to provide a kind of dry heat sterilization chemical indicating card, easy to use, visual result is accurate.
Dry heat sterilization chemical indicating card of the present invention is characterized in that being coated with indicator on ivory board, the weight percent of indicator consists of:
Resin 20～30%
Cupric nitrate 5～10%
Tartrate 1～3%
Pimelinketone 50～60%
Yellow soda ash 10～20%.
Indicator is that resin carrier is mixed with cyclohexanone solvent, being stirred to resin is dissolved in the solvent fully, adding cupric nitrate and tartrate reactant add the yellow soda ash control agent again and stir after 1 hour, are ground to Hegman grind gage measurement fineness with three-roll grinder to make less than 3 microns again.
Indicator can adopt the silk screen plate printing process to be coated on the ivory board.
The paperboard that will be printed on indicator is tailored into required card and is got finished product.
Indicating card of the present invention, through 160 ± 2 ℃, 120min; 170 ± 2 ℃, 60min; 180 ± 2 ℃, after the dry sterilization process of 30min, indicator becomes and reaches or be deeper than reference colour.
Compared with prior art, the present invention has following beneficial effect:
Use the chemical indicating card of the present invention to detect the dry sterilization effect, simple, the easy row of method, visual result, accurate.
By adjusting indicator, can satisfy the needs that the differing temps sterilization requires, reach the standard that hospital's sterilization is used.
