Remotely detectable sterilization monitor

摘要

A monitor for detection of temperature and/or steam conditions indicative of sterilization. The monitor comprises means for creating a remotely detectable response upon interrogation by an electromagnetic field and means for changing the response upon exposure to a predetermined set of temperature and steam conditions. The remotely detectable response is preferably produced through the interaction of an electromagnetic interrogation field with magnetic components of the monitor, wherein the characteristic harmonic response generated by the magnetic components is either inhibited or enabled by the change in configuration of one or more elements of the detector. Sterilization conditions are detected through one or more compounds known to have melting points which are above the temperature used in the sterilization process. Melting of the chemical compound produces the change in configuration of the element or elements of the monitor.
