STERILE SERVICES
reprocessing. It can also lead to the break-up of an established decontamination team. You really don’t want to lose a team of trained decontamination technicians while you do a refurbishment.”
News of the success of the temporary facility at Bath has certainly caused a stir. “We had nine different sites come to have a look, equipment manufacturers too,” said Garth. “They were keen to look at how we had done it and particular to know what we charge.”
Reliable equipment
As a mark of their reliability, a number of Envirogen RO machines are already installed across the Bath hospital site, where they ensure the quality of the water supplied for key equipment. They were also chosen for the nearby temporary endoscopy unit and for both areas of the newly centralised sterile services and endoscope reprocessing unit. Two portakabin buildings, built to SSD’s structural specifications, house the temporary sterile services facility. A 7.28m2
portakabin
building, with a reinforced floor, forms the plant room, housing a duplex EndoTherm Duo RO system from UK manufacturers Envirogen, to feed the washer-disinfectors. The EndoTherm Duo model houses two separate RO units within the same cabinet. Having two RO units gives 100% resilience, allowing for scheduled maintenance/service when required without the loss of purified water.
The EndoTherm Duo has its own ring main feeding RO water to all three washer-
disinfectors. It was also supplied with two duplex water softeners, one to feed the duplex EndoTherm Duo RO system and one to feed the cold softened process water to the washer-disinfectors. Allan Wigglesworth, healthcare market manager for Envirogen, said: “We have a long- standing relationship with Bath and were very pleased that SSD chose our equipment for the scheme. It’s the first EndoTherm Duo duplex install for a temporary instrument reprocessing facility, but yet again it’s delivered 100% reliability.”
The adjacent production unit is a 10m by 35.80m2
portakabin building with a
reinforced floor and air conditioning units. The receiving area has twin bowl sink for items which require manual washing. Instruments for processing are placed on 18 Din trays and loaded into one of the three, compact, high capacity Franke D EKO D32 Excel pass-through washer- disinfector-dryers, supplied by Dekomed. The DEKO D32s Excels are designed and constructed to exceed the standard performance and design requirements stated in ISO/DIS 15883-1 Washer-disinfectors - Parts 1 and 2: and IEC 61010-2-45. They guarantee process results throughout with a Class C independent, full process verification recording system. Water pressure for washing is via a high-powered circulation pump. Pipework and the number of loading shelves fitted with rotating spray arms are calculated to have the maximum soil removal efficacy. Washing spray patterns delivered
through five rotating spray arms are purpose- designed racks to guarantee contact with all surfaces and crevices of instruments with the most intricate design.
The machines offer a wide selection of disinfection temperatures and cycle times to secure the microbial killing impact. The unit’s touch screen technology displays a range of information throughout the cycle, together with service actions and routine checks. As is the case at Bath, cycles can be altered to meet almost any special requirement. Once the cycle is complete, the pass- through machine is unloaded into the Class 8 cleanroom, where the instruments are checked and wrapped ready for despatch to the sterilisers. Steve Townsend, projects manager at Dekomed, said: “We liaised closely with Garth and the SSD team throughout the installation, commission and operation of the temporary reprocessing unit to ensure the machines delivered a first-class service.” With the new centralised sterile services and endoscope reprocessing department now operational, the temporary sterile services unit has been decommissioned. It delivered over six months of virtually faultless operation, which enabled the Trust to meet the increased demands placed upon it. Indeed, it was so successful that theatre teams hardly realised what was happening. What initially looked like ‘mission impossible’ for Royal United Hospitals Bath NHS Foundation Trust proved to be ‘mission achievable’.
