as it strives to meet the demand of its busy endoscopy services. “When it comes to sizing the water treatment plant, our water consumption is also one of the lowest on the market, at only 33 litres of water per cycle. There is a lot of pressure on the NHS, at the moment, to improve sustainability and this was another important factor for the Trust. It takes its environmental responsibilities extremely seriously,” added Doherty. “When you are looking at 10,000 cycles a year,
this is a lot of water saved. In addition to that, we have also reduced the amount of plastic waste for detergent and disinfectant. This was another important consideration for the Trust.” To ensure complete cleaning and disinfection
of endoscopes, the WD440 PT machines contain a unique basin and helical tube system. Fluid flows through the helical tube suspending the distal end in the process liquids allowing for a highly efficient wash and disinfect process of the whole endoscope. To guarantee a safe and traceable appliance
of process chemicals and bacterial filters, the machines are also equipped with radio- frequency identification (RFID). Before starting a process, the EWD will verify the right position of cans and filters, and checks on exceeded expiry dates and other critical parameters, thereby eliminating the risk of human error. The user interfaces of the WD440 PT
machines are designed around intuitive and touchless operation. Handsfree operation of the lid, using foot switches, reduces the risk of cross-contamination, while clear LED bars in the front panel of the machine indicate the status of the process. Colour-coded connection material also facilitates easy and flawless endoscope connection, assisted by an intuitive colour touchscreen that guides the user through all necessary steps. “We now have 16 bowls and 8 machines which means our capacity has significantly
increased. One of the main benefits we have witnessed is the speed and efficiency of the new washers in comparison to previous versions. The decontamination staff like the machines’ function and find the EWDs easy to use. They use less water and detergent which means they are also more cost effective,” commented Osler. “The LED light function is a great help when
training, as this indicates the current state of the machine at any point in time, and everything is colour coordinated which again makes the EWDs very user friendly. Furthermore, the machines are quicker than before, so we can complete a large amount of work, during the day.” Traceability is also key for the Trust to ensure compliance with guidelines. The integrated traceability of the WD440 PT solution supports the user in achieving compliance with applicable quality systems. All steps of the cleaning and disinfection process can be traced and monitored in detail, with a report sent to

an integral printer or via Process Manager software. Process data is collected and provides meaningful information about all processes that have occurred in the washer-disinfector. Wassenburg’s 360-degree track and trace capability integrates seamlessly with the Trust’s Health Edge IT system and other third-party systems. The Health Edge Scope Application (HESA) enables the end users to record the full decontamination process, including patient association. With reprocessed scopes being supplied across sites, visibility is vital.
Drying, storage and transportation The Trust also needed a solution for drying and safe storage of the scopes, so Wassenburg Medical as the approved supplier through the NHS supply chain framework partnered with Pentax to deliver the optimum solution. (Wassenburg Medical is partly owned by parent company, the Hoya Corporation, while Pentax is owned in full). Insufficient drying can be a source for
microbial contamination and the transmission of infectious material. However, the PlasmaTYPHOON is designed to reduce the risk of infection by perfectly drying the scopes. The ultra-fast drying unit helps increase efficiency and capacity for the unit, while active storage in a PlasmaBAG allows the storage of endoscopes – preserving the disinfection level already achieved. In addition, the storage bags possess the benefit of being part of a carbon neutral scheme. A significant advantage is the fact that scopes can be stored in the PlasmaBAG for up to 31 days.* This makes it convenient for transportation between the three sites – an important factor once the Trust’s decontamination service was centralised. The system also offers improved
