Richard Bancroft, BSc (Hons), science and technical director at STERIS Corporation explores alternatives to parametric release when disinfecting or sterilising medical devices.
Reusable medical devices such as surgical instruments are reprocessed in healthcare facilities; this reuse entails washing and disinfecting, inspection, packaging and sterilisation. The process of releasing the load as sterile is of critical importance for patient safety; the load may be released based on the results of physical parameter monitoring of the load and is known as parametric release.
In order to improve the safety of medical devices released parametrically, it is preferable that data from the physical parameters that are critical to the success of the process be independent from the process controller data.
