Internal affairs – cleaning the bloody mess (the one about washer disinfector cycle optimisation)

Everyone talks about optimising washer disinfector cycles and I have presented my holistic approach to the subject before in the Volume 19, No. 2 issue of this journal. Since that time, however, there was a significant development on the statutory side of things – we now have an official goal to achieve – put it simply, 5µg per side per …

Prewash, Mainwash and Greenwash – sustainability in decontamination context

This is really a continuation of the line of thinking from one of my first blogs/articles entitled “process versus result”. This time explored through sustainability, a big word that is now in fashion. Sustainability is often simplified to “being green” and “eco”. These words, however, divert attention from the true essence of sustainable development. An often cited definition explains sustainable …

Robots, robots everywhere!

Picking up on my presentation at IDSc Conference in Blackpool, I wanted to expand on the thought of introducing robotics and automation into the decontamination environment. And at the beginning, I need to stress out that I am not talking about a robot to automate a single task but about an entire robotised infrastructure that will automate the whole  decontamination …

Process versus the result

Washer disinfectors follow strict processes to deliver clean and safe to handle instruments ready for sterilization. Over the years I have been looking into different designs of washer disinfectors but the process itself was rarely a subject for consideration. Parameters were adjusted within a rigid framework of initial rinse, main wash with chemical, rinse and disinfection stage. And do not …

It’s not the Washer-Disinfector – It’s how you use it!

The validation report of a Washer-Disinfector clearly specifies the test load. Modern cleaning machines are designed for the shortest possible cycle times to maximise instrument throughput and save energy. Because of that, even a relatively small difference from the way the test load was used may result in a “failed” cycle. It is therefore critical to arrange instruments and accessories …
