Abstract

The present invention is a method for real-time location monitoring of a sterilizable object. The method includes tracking a location of a sterilizable object bearing a tag using a mesh network. The tag preferably includes a sealed housing, means for detecting a sterilization event and means for transmitting data concerning the sterilization event. The method also includes detecting a sterilization event. The method also includes transmitting a signal that the sterilization event has been detected by the tag.

Claims (4)

1. A method for real-time location monitoring of an object within a hospital, the method comprising:

tracking a location of an object bearing an RFID tag within a hospital using RFID tag transmissions to at least one of a plurality of sensors within the hospital, the plurality of sensors forming a mesh network;

determining if a location of the object varies from a pre-determined workflow for the object, the predetermined workflow comprising detecting the object at a cleaning location for a predetermined period of time through transmissions from the tag to at least one of the plurality of sensors corresponding to the cleaning location, and detecting a cleaning event, wherein the cleaning event is at least one of a chemical disinfectant cleaning wherein a sterilization threshold value of hydrogen peroxide in a concentration amount of at least 6% is detected by the tag and transmitted to said at least one of the plurality of sensors, an ultrasonic cleaning wherein a sterilization threshold value of a pre-established amount of ultrasonic energy is detected by the tag and transmitted to said at least one of the plurality of sensors, a steam cleaning wherein a sterilization threshold value of water vapor at a temperature of at least 100° C. is detected by the tag and transmitted to said at least one of the plurality of sensors, and a high temperature cleaning wherein a sterilization threshold value of a temperature of at least 150° C. is detected by the tag and transmitted to said at least one of the plurality of sensors; and

notifying an operator upon determining that the location of the object varies from a predetermined workflow for the object.
