Steris Reliance EPS CYCLE DESCRIPTION

IMPORTANT: Items to be high level disinfected must be manually pre-cleaned according to manufacturer recommendations before being placed in the endoscope processing support.

Processing Cycles

There are four processing cycle options to choose from:

  1. SINGLE Endoscope Processing Cycle With Washing Phase
    • Used to process one endoscope through washing and high-level disinfection (HLD) phases.
    • The endoscope is placed in control handle boot “A.”
  2. SINGLE Endoscope Processing Cycle Without Washing Phase
    • Used to process one endoscope through a high-level disinfection phase only.
    • The endoscope is placed in control handle boot “A.”
  3. DOUBLE Endoscope Processing Cycle With Washing Phase
    • Used to process two endoscopes through washing and high-level disinfection phases.
    • One endoscope is placed in the control handle boot “A” and one in control handle boot “B.”
  4. DOUBLE Endoscope Processing Cycle Without Washing Phase
    • Used to process two endoscopes through a high level disinfection phase only.
    • One endoscope is placed in control handle boot “A” and one in control handle boot “B.”
  • Processing Cycle Description
    • The total default cycle time with a washing phase is approximately 42 minutes.
    • The total cycle time without a washing phase is approximately 30 minutes.
    • Cycle time depends on the washing cycle settings entered in Supervisor mode.
    • Temperature, pressure, and quality of the building water supply can also influence cycle time.
  1. The First Phase of the Processing Cycle is an Optional, Programmable Washing Phase
    • This phase consists of a wash with Klenzyme Enzyme Presoak and Cleaner, followed by a rinse.
    • The washing phase can be programmed ON or OFF.
    • In the ON mode, the user can choose either one or two washing phases per processing cycle.
    • Additionally, the wash segment duration can be adjusted to be between 5 and 10 minutes.
    • The Reliance Endoscope Processing System washing phase does not replace manual pre-cleaning by the user.
  2. The Second Phase of the Processing Cycle
    • A required high-level disinfection phase and cannot be adjusted by the user.
    • In this phase, the single-use container Reliance DG chemistry is dissolved with water at 122°F (50°C) and circulated throughout the processor and through the device lumens.
    • During the first four minutes of this phase, peracetic acid is generated from the dry components creating the germicidal high-level disinfection solution.
    • This solution generation is followed by a six-minute high-level disinfection phase at 122°F (50°C).
  3. The Third Phase of the Processing Cycle
    • A required rinse phase and cannot be adjusted by the user.
    • The Reliance Endoscope Processor removes the high-level disinfection solution using two rinses.
    • The processor filters the rinse water (as well as all of the water used throughout the cycle) through a 0.2 μm bacterial-retentive filter.
    • The processor also incorporates an automatic internal integrity check of the filter at the end of each processing cycle.
    • If the integrity check fails, the user is alerted by an alarm and the cycle printout indicates a fault code for this filter integrity failure.
  4. The Fourth and Last Phase of the Processing Cycle
    • An air purge phase using HEPA-filtered air.
    • The air purge helps to remove excess rinse water from the processed devices.
    • The final air purge is preset to run for four minutes; additional air purge time may be selected by the operator for up to 30 minutes.
    • If the devices are not removed from the processor at the end of the cycle, the air purge phase will continue for up to a maximum of 60 minutes.
  • Decontamination Cycles
  • The processor also features Two decontamination cycles intended to prevent biofilm formation in the chamber and on the endoscope processor support.
  1. The First is Called D-SHORT
    • Consists of hot water at 180°F (82.2°C) circulating through the processor for 13 minutes, followed by a 10-minute hot air purge at 240°F (115.6°C).
    • This cycle must be run every 54 hours.
    • If a D-SHORT cycle is not completed within this time interval, the processor is locked out from use until a D-LONG cycle (see below) is run.
    • D-SHORT is intended to prevent biofilm formation and contamination.
  2. The Second Decontamination Cycle is Called D-LONG
    • Consists of a cycle in which CIP 200 Acid-Based Process and Research Cleaner is added to hot water at 180°F (82.2°C).
    • The washing solution is then circulated through the processor for 20 minutes; this is followed by three rinses to remove the solution from the processor and a 10-minute hot air purge at 240°F (115.6°C).
    • D-LONG is to be used on those occasions when the D-SHORT cycle has not been run within the past 54 hours.
    • D-LONG is intended to prevent biofilm formation and contamination.
  • Steris Reliance EPS TEST Cycle
    • A TEST cycle program is available for service and maintenance.

Steris Reliance EPS TECHNICAL DATA

  • Control System
    • Control system consists of microcomputer control boards and peripheral function circuit boards, located within the control board housing.
  • Electronic Temperature Control
    • Resistive Temperature Device (RTD) sensors are used instead of conventional thermostats, to provide accurate control inputs and readouts throughout all phases of the cycle.
  • Electronic Pressure Monitoring
    • Two pressure transmitter sensors are used to provide control measurements and readouts of the pressure developed within both control handle boots during the washing (optional) and HLD phases.
    • A third pressure transmitter sensor is used to provide accurate pressure measurements during Filter Integrity Pressure Hold Test.
  • Internal Battery
    • An internal battery backs up all cycle memory for up to 10 years.
    • If a power failure occurs during a cycle, the battery back-up system ensures that cycle memory will be retained and proper cycle completion will occur once power is restored.
    • When power is lost, the cycle is held in phase until power is restored.
    • Once power returns, the event is recorded on the printout and the cycle automatically resumes or is aborted, depending on which phase the cycle was in at the time of power loss.
