    Abstract: A biological sterilization indicator (BI) is provided. The BI can include a housing, and a container positioned in the housing. The BI can further include a first chamber, and a second chamber with a source of biological activity disposed therein. The BI can further include a substrate positioned in the housing between the first chamber and the second chamber. The substrate can be positioned in fluid communication with the first chamber and the second chamber, and the substrate can be further positioned such that the substrate is not in direct contact with the source of biological activity. The substrate can comprise a hydrophobic nonporous film having an aperture. The substrate and the aperture are dimensioned to control fluid flow between the first compartment and the second compartment. The substrate can extend around substantially the entire inner perimeter of the housing between the first compartment and the second compartment.

    Abstract: A sensor device includes a first electrode and a second electrode. Each of the first and second electrodes are electrically coupled to an electrical bridge. The electrical bridge includes a conductive polymer having a first impedance state and a second impedance state that is different than the first impedance sate. The electrical bridge includes metal or metal containing particles.

    Abstract: A system for disinfecting an enclosed space includes an ultraviolet (UV) disinfection assembly, a sensor to detect occupancy in or entry into the enclosed space, and a controller. The UV disinfection assembly includes UV emitters. The controller controls operation of the UV emitters to carry out disinfection operations, each of a predetermined UV dose. The controller activates a disinfection operation in a first mode when: (1A) the sensor indicates no occupancy in or no entry into the enclosed space. The controller activates a disinfection operation in a second mode when: (2A) the sensor indicates no occupancy in or no entry into the enclosed space, and (2B) there is a qualified human input through a human-machine interface (HMI) in communication with the controller. The controller suspends or deactivates the disinfection operation when the sensor indicates occupancy in or entry into the enclosed space.

    Inventor： BALA, Harry

    IPC: A61L2/28

    Abstract: A sterilization challenge device (10) for verifying the efficacy of a sterilization process includes a container (12), an insert member (16), a sterilization indicator (18), and a cap (14). The container (12) includes an open end (22), a closed end (24), a chamber (20) configured to contain the biological indicator (18) and the insert member (16), and at least one hole (36) arranged proximate the open end (22). The cap (14) is configured to engage with the container (12) to close the open end (22), and the at least one hole (36) is configured to provide a flow path for the gaseous sterilant into the chamber (20).

    Abstract: Disclosed is a method for validating a decontamination procedure performed using a decontamination system that comprises a first product for use in a first step of the procedure, such as a pre-clean step, and a second product for use in a subsequent second step of the procedure, such as a disinfection step. The method comprises capturing a video stream of a work area in which the decontamination procedure is carried out by a user, analysing the video stream to identify when the first product is present in the work area and when the second product is present in the work area, determining, based on said identification, that the first and second products have been presented in the correct order in the decontamination procedure, and causing a corresponding indication to be provided to the user. The method may include alerting the user to potential errors and/or logging data to provide an audit trail.
