Abstract

A system for monitoring concentrations of sterilant, such as hydrogen peroxide vapor, within a sterilization apparatus, includes a self-contained, sterilant monitoring assembly that is freely positionable within the sterilization apparatus. The assembly includes a gas-detecting sensor and associated temperature sensor mounted on a portable structure, as well as a suitable data collection circuit for receiving output signals from the sensors. The assembly also includes signals connectors, such as a physical data port or a remote transmitter, or both. Signals can be transmitted concurrently with data collection, or an electronic memory may be provided for subsequent transfer of the collected data. Collected data is transferred to a remote communication unit positioned exteriorly of the sterilization apparatus. The collected data is processed by a processor, which is either provided as part of the monitoring assembly or provided remotely as part of the monitoring system as a whole, to identify the corresponding detected sterilant levels. The assembly is operated by a power source, which can be activated manually, by preprogrammed relays, or remotely by a control system capable of receiving control signals via near infrared or radio wave transmissions. A carrier element is provided to carry the sterilant monitoring assembly along the conveyor path of the sterilization apparatus and, thus, collect data at each sterilization station.
