STERILISATION INDICATOR Russian patent published in 2012 - IPC A61L2/28 A61L2/14 

FIELD: medicine.

SUBSTANCE: group of inventions refers to sterilisation and may be used to check sterilisation parameters in a post-arc chamber. The sterilisation indicator comprises a compound heated when contacting oxygen and/or nitrogen atoms, and a thermochromic pigment thermally contacting said compound. Besides, the indicator may consist of two portions one of which contains the compound heated when contacting oxygen and/or nitrogen atoms, and the thermochromic pigment thermally contacting it, and another one is the thermochromic pigment free from the compound heated when contacting oxygen and/or nitrogen atoms. The group of inventions refers to using the indicator in a sterilisation device for oxygen and/or nitrogen atom indication and temperature indication in the post-arc chamber. Also, the group of inventions characterises versions of the method for oxygen and/or nitrogen atom indication in plasma in the post-arc chamber and temperature indication in the post-arc chamber by means of declared sterilisation indicator contacting plasma and comparison of the indicator pigment colour with reference colours.

EFFECT: group of inventions enables checking the sterilisation parameters for object sterilisation with using plasma on the basis of nitrogen or oxygen.
