The most important analyte used to verify the cleanliness of a medical device after a cleaning process is protein [1, 2]. There are a variety of different Assays to test for protein, the most commonly used Assays are based on ortho-phthalaldehyde (OPA) and bicinchoninic acid (BCA) [2]. In this study 42 different cleaning detergents from 14 different manufacturers were tested for their potential to influence the output of these Assays.
The members of the Institute of Decontamination Sciences (IDSc) held their annual conference as usual in early December, but on this occasion at a new venue in Hinckley, Leicestershire.
The start to the new year was kicked off with an unpleasant surprise. A novel coronavirus, known as 2019-nCoV, is spreading very rapidly. So far, it has affected mainly people in the Hubei province of China. A few days ago the World Health Organization (WHO) declared this outbreak to be a Public Health Emergency of International Concern (PHEIC). That sounds alarming. The hygiene measures taken to control the outbreak are accordingly radical. What does this virus really mean?
Steam sterilisation conditions are not unambiguously quantified in the literature and standards. In practical situations, it would be helpful if a set of criteria to assess the actual surface steam sterilisation conditions would be available.
A review of the literature and standards is performed. Results from this review, combined with basic physical calculations, are used to determine numerically quantified steam sterilisation conditions.
Requirements for Construction or Reconstruction of a Reprocessing Unit for Medical Devices (RUMED)

Part 11: Heating, ventilation and air conditioning (HVAC) system in a RUMED
Part 11 of the publication series “Requirements for Construction or Reconstruction of a Reprocessing Unit for Medical Devices (RUMED)” focuses on the heating, ventilation and air conditioning (HVAC) system in a RUMED.
The present study investigated the formation and fixation of silicate deposits during steam sterilization. First, transfer of silicic acid from the feed water into the sterilization steam onto the sterile supplies was analysed in theory by comparing the process parameters of all substeps of a typical steam sterilization process with a solubility diagram for silicic acid in water and in steam.
The Bowie-Dick (BD) test is performed daily as well as in the weekly, quarterly, annual and revalidation tests. When an autoclave undergoes a maintenance or repair procedure, the autoclave should return to service in a short time in the busy environment of acute care units: an operating theater and so on.
Part 10 of the publication Requirements for Construction or Reconstruction of a Reprocessing Unit for Medical Devices (RUMED) focuses on compressed air for medical use, generally known simply as medical compressed air. Part 11: Heating, ventilation and air conditioning (HVAC) system in a RUMED
At the World Forum Congress Centre in The Hague the focus over those days was on medical device reprocessing – over 1,800 delegates from around the world had turned up to attend the World Congress.
Rigid sterilization containers are designed as a sterile barrier system to preserve the sterility of the enclosed contents. Although they are claimed to have a lengthy life span, it is a concern the sealing capability along the gasket seal because wear and tear may compromise the sealing capability.
Part 9 of the publication Requirements for Construction or Reconstruction of a Reprocessing Unit for Medical Devices (RUMED) focuses on the supply/process media for a reprocessing unit for flexible endoscopes.
It serves as guidance for new construction or reconstruction of a RUMED for flexible endoscopes with regard to the technical requirements to be met for the supply and disposal of the different media needed.
