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 …

Washer-Disinfector design features for efficient wash

The efficient wash must also be repeatable and it is these two features that create the desired combination. The most important feature of conventional Washer-Disinfectors is distribution of the cleaning action within the entire chamber, meaning that cleaning solution (water + chemical) reaches all surfaces of instruments and accessories and at the same time ensures the chamber itself is also …

A couple of thoughts on the Edinburgh Test Soil

This post is an elaborated version of my recent Linked In comment in the group HTM2030 and EN ISO 15883 Washer Disinfectors I have been involved in countless tests of Cleaning Efficacy as every time a new WD is developed an optimum cycle must be determined. Edinburgh test soil is one of the “human fluids” resembling substance we have used …
