Sterilization chemical indicator

Abstract

The present disclosure relates generally to chemical indicators. In particular, the chemical indicators are useful for monitoring sterilization processes. The chemical indicator includes a fluid pathway and a chamber comprises a chemical-indicating composition.

Description

[0001] The present disclosure involves chemical indicators for monitoring the sterilization process. Background technique [0002] Medical instruments, especially surgical instruments, typically sterilized using steam or other sterilized gases or liquids prior to use. The commonly used sterilization process is to expose the instrument to the steam under pressure. Alternative sterilization processes use a gas such as ethylene oxide and hydrogen peroxide as a sterile agent. The use of hydrogen peroxide and other chemical gas phase sterilization techniques generally relates to a temperature sensitive temperature than steam sterilization temperature, and thus applicable to temperature sensitive means, such as those including plastic. [0003] Sterilization Indicators are used to monitor whether sterilization processes have been performed and / or whether key sterilization parameters have been met. Sterilization indicators typically include a chemical indication composition carrying on ...

Problems solved by technology

For the design of hydrogen peroxide sterilization indicators, another factor that comes into play is the high oxidizing power of hydrogen peroxide, which can cause the indicator to change color too quickly to make it unusable for monitoring the sterilization integrators required.
