A sterilization system includes a vial, a carrier of microorganisms disposed in the vial, and a fluid management system having an output connectable to the vial for delivering a liquid chemical sterilant and a neutralizer thereto. Additionally, a growth medium may be delivered to the vial such that the vial and growth medium may assessed for a change to a visual characteristic indicative of sterilization inefficacy.

Liquid-chemical sterilization system with biological indicator

A method to improve efficiency of operating a sterilizer is disclosed. The method includes determining a volume of a load inside the sterilizer based on pressure measurements as a function of time. The determined volume may be used to decide whether to conduct a sterilization procedure. If the sterilization procedure is to be conducted, the volume data may be used to estimate the duration of the procedure, which duration may be communicated to a user.

Load volume determination method for a sterilization apparatus

Disclosed herein are biological indicators suitable for use in a liquid-chemical sterilization process that may be conducted by an automated endoscope reprocessor. The biological indicator may include one or more ports for introducing and removing a liquid-chemical sterilant therefrom. The biological indicators may include features, such as a declivity leading to a port opening or a pipette, that may assist in transferring the liquid-chemical sterilant. The system may additionally include a holder having features that facilitate use of the system and biological indicators.

Biological indicator for liquid-chemical sterilization system

A method and a system for determining analyte content in a fluid in a treatment apparatus. The method comprises positioning a device for treatment in a treatment apparatus. A surface of the device is contacted with a fluid. An analyte content in the fluid is determined based on an electromagnetic property of the fluid following contacting the surface of the device with the fluid. More specifically, an electromagnetic property is measured. The measuring comprises emitting electromagnetic radiation into the fluid in the treatment apparatus and detecting electromagnetic radiation from the fluid. In another aspect, a system comprising a treatment apparatus and a detector for determining the analyte content in the fluid in the treatment apparatus is provided.

Method and a system for determining analyte content in a fluid in a treatment apparatus

A biological indicator analyzer includes a plurality of wells, a plurality of organism detector features, and a user input feature such as a touch screen. Each well is configured to receive a respective biological indicator. Each organism detector feature is configured to detect whether a biological indicator disposed in a corresponding well of the plurality of wells contains a living organism. The touch screen is configured to receive user input and provide information to the user indicating a status of biological indicator analysis. The biological indicator analyzer may be used to analyze a biological indicator that was positioned in a sterilization chamber of a sterilizing cabinet along with at least one medical device that is to be sterilized. The analysis may indicate whether the sterilization cycle in the sterilization chamber as successful.

Method of sterilizing medical devices, analyzing biological indicators, and linking medical device sterilization equipment

A sterilizing cabinet performs a method of processing a medical device, such as a used medical device or an otherwise non-sterile medical device. The method includes receiving input from a user selecting a sterilization cycle from a plurality of available sterilization cycles. The sterilizing cabinet identifies a biological indicator associated with the selected sterilization cycle. The sterilizing cabinet prompts the user via a touch screen display to place the medical device and the biological indicator into a sterilization chamber of a sterilizing cabinet. The sterilizing cabinet performs load conditioning on the medical device in the sterilization chamber. The sterilizing cabinet then performs the selected sterilization cycle on the medical device in the sterilization chamber after completing the act of load conditioning.

Apparatus and method for analyzing biological indicators

The effectiveness of an oxidative sterilization process is determined by exposing a known amount of a primary amine or aldehyde indicator chemical to an oxidative germicide. The oxidative germicide reacts with the indicator chemical. The amount of indicator chemical remaining after exposure to the germicide is determined by reacting the indicator chemical with a dye precursor chemical to form a colored product. The amount of indicator chemical remaining is determined from the intensity of the color of the colored product. The amount of indicator chemical remaining on the substrate is a measure of the effectiveness of the germicidal treatment. The dye precursor is an aldehyde when the indicator chemical is a primary amine and a primary amine when the indicator chemical is an aldehyde. An integrator for determining the effectiveness of the germicidal process includes an indicator chemical, where the indicator chemical is a primary amine or an aldehyde.
