An innovative system to sterilise medical devices at low temperatures

For those in a surgical environment it is crucial that reusable equipment goes through aneffective decontamination and sterilisation process to avoid cross infection of patients.Steam sterilisation has been accepted as effective, but there are many items that containheat labile materials, and therefore require ‘cold’ sterilisation. CISA’s response to this needhas been the design of the SPS, an innovative piece of equipment meeting the challengesof effectiveness, safety, applicability, versatility, capacity, and cost.

The technology behind the SPS is the creation of PLASMA, the fourth state of matter,alongside solid, liquid, and gas. In this state, molecules and atoms become ionised andcarry a high energy which has been shown to be effective in decontamination andsterilisation. The original technology has been available for some time, and has turnedout to be the ideal basis on which to develop a new generation of sterilisation device withan innovative approach to performance.

Sterilisation at low temperatures with PLASMA, in combination with hydrogen peroxide,produces results that show marked improvements as compared with other currentlyavailable cold sterilisation techniques.

The speed of PLASMA sterilisation and, at the end of cycle, the immediate availability ofthe sterilised equipment, means that the sterilised equipment can be used again morequickly and frequently, reducing waiting times and inventory costs.

Plasma

The CISA SPS system for generating PLASMA has been created following an in-depthlong–term research programme to make the system fully appropriate for hospital sterilisation.

The PLASMA is created by means of direct current pulses which start the process of ionisation, excitation, and photoionisation of the gas molecules remaining in the sterilisationchamber after a high vacuum has been achieved. Sterilisation is achieved by a combinationof the ultraviolet radiation generated by the PLASMA, the energy dissipated into the materials,and the action of hydrogen peroxide.

Micro-organisms are destroyed by the oxidising action of the ions and free radicals createdby the PLASMA, attacking cell walls and the molecules inside the cells.

In the conditions created in the SPS, the PLASMA makes it possible to carry out the sterilisation process in a relatively short time and at relatively low temperatures (40-450C),maintaining the integrity of the surgical equipment being reprocessed. The nature of thePLASMA means that the sterilant is removed from the surfaces of the equipment, leavingno residues, meaning that the equipment is available for immediate use at the end of thecycle.

Applicability and throughput

The CISA PLASMA sterilisation system is easy,quick, and capable of sterilising the majority ofsurgical heat labile equipment used in theatre.

The sterilant pervades the whole chamber, ensuring full sterilisation of all materials, wherever situated. A series of technical innovations enables sterilisation of difficult toreach spots, such as the ends of 1500mm closed end lumens.

The capacity of the chamber (300 useable litres),the chamber’s shape, and the SPS’s speed of performance, makes it possible to sterilise alarge quantity of material in a short time, providing a high level of productivity from thesteriliser.

The steriliser can be included in a normal sterilising room, alongside high temperaturesterilisers. The SPS is available in both cabinetand pass-through models.

Safety

Safety

The steriliser incorporates the most sophisticatedsafety controls relating to the functions for whichthe SPS has been designed. The SPS is classifiedClass IIa (European Directive MDD 93/42), and provides full protection for the operator, the steril-isation loads, the patient, and the environment.

Within the steriliser, each critical component is backed up by a secondary system which automatically comes into action if the primarycomponent malfunctions, or programmed parametric conditions are not met.

Analysis of the parametric data, and cross comparison with accumulated data, makes it possible to repeat accurately the sterilisationprocess, thus avoiding the need for the operator tomake independent analyses of each cycle.

All cycles are managed by systems controlled byprogrammable logic (PLC), making it possible to monitor each cycle, its parameters, and overallsafety.

The SPS has two PLCs which are in constant communication with each other to maximise security and safety. While one PLC is running theSPS’s operations, the second is continuously supervising, verifying, and recording the process.An easily interpreted report in both data andgraphical format is generated for each cycle.

Surgical equipment can be treated as with anyother sterilising system with respect to track andtrace and other equipment-monitoring systems.

Operators and patients can be assured of theirsafety from any side-effects from the sterilant inthat, at the end of a cycle, there is no residue onthe equipment since, as part of the process, thesterilant breaks down into simple harmless by-products such as water.

Thus, all effluent from the SPS provides no risk tothe environment, and there are no restrictions onoutput to the hospital drain system.

The CISA PLASMA sterilisation system is ecologicallysound and non-toxic, as it leaves no residue on theequipment, and the effluent is biodegradable.

Low Operating Costs

Maintenance

The SPS has been designed to guarantee long-term reliability. State of the art componentshave been selected and these, combined with innovative engineering principles, haveresulted in lower maintenance costs.

Front access, positioning of component parts, and selected technical approaches, makethe equipment more accessible, and therefore maintenance is simplified.

The use of two vacuum pumps, one with a liquid ring for initial evacuation, and the othera dry pump for high-level evacuation, extends the lives of the pumps, and thereby reducesmaintenance needs considerably.

A touch screen gives access to information as to the length of time left before a part needsroutine maintenance or replacement.

Consumables

Operating costs are reduced by the use of consumables which are readily available commercially.

Widely available products suitable for use for PLASMA sterilisation may be used to packagethe loads to be sterilised, as well as to monitor chemically and microbiologically the efficacy of the sterilisation process.

Sterilisation Cycle

Operator interface with the SPS is through atouch screen. By this means the operator canboth run and monitor the performance of eachworking cycle.

Extensive research with the SPS has shown thatonly two types of cycle are required to cover allhospital needs. Thus, cycles can be selectedeither for flat surfaces or for cannulated items.Pressure changes during a sterilisation cycle

Technical Data

The sterilant is a chemical solution includinghydrogen peroxide in a special container.

The container is, in turn, contained within asolid cassette which has been designed for safehandling and transportation, as well as for easeof insertion into the SPS.

All handling of the liquids, including sterilantextraction, is carried out by completely auto-mated processes once the cassette has beeninserted.
