SYSTEM 1E® Liquid Chemical Sterilant Processing System

The SYSTEM 1E Liquid Chemical Sterilant Processing System is for safe and effective reprocessing of heat-sensitive critical and semi-critical medical devices and is a practical solution for low-temperature liquid chemical sterilization of complex flexible endoscopes, such as duodenoscopes used in endoscopic retrograde cholangiopancreatography (ERCP) procedures.

How SYSTEM 1E® Liquid Chemical Sterilant Processing System Works

Liquid chemical sterilization enables rapid, efficacious reprocessing of cleaned, reusable, immersible, and heat-sensitive critical and semi-critical medical devices. The system utilizes S40® Sterilant Concentrate to eliminate all microbial life, including bacterial endospores. The S1E processor, two pre-filters, UV irradiation and a MaxPure™ filter work in harmony with S40 Sterilant Concentrate to provide a validated process for critical and semi-critical, heat-sensitive devices. The gentle use-dilution protects delicate surgical instruments, including multi-channel flexible surgical endoscopes. The use-dilution is neutral pH and rinses safely down the drain. Quick Connect adapters are designed to leak to ensure sterilant use dilution reaches all surfaces and angles of the device ports.

Why SYSTEM 1E® Liquid Chemical Sterilant Processing System?

The SYSTEM 1E processor will help you process your devices with confidence. Its compact footprint and rapid 23 minute cycle time makes it convenient and ideal for a variety of locations. Compared to high-level disinfection, it provides a higher level of reprocessing assurance for heat-sensitive critical and semi-critical devices such as flexible or semi-rigid endoscopes.

S40 Sterilant Concentrate

  • Single-use chemistry labeled exclusively for use in the SYSTEM 1E Liquid Chemical Sterilant Processing System.
  • Its active ingredient is peracetic acid, an effective liquid chemical sterilant.
  • The chemicals also minimize corrosion or degradation of the devices being processed.

LIQUID CHEMICAL STERILIZATION MONITORING

NOTE: As with any processing method, effective liquid chemical sterilization in the SYSTEM 1E Processor requires proper cleaning, preparation, and placement of devices. Before processing any device in the SYSTEM 1E Processor, the user must ensure that the reprocessing instructions provided by both the device manufacturer and STERIS are completely understood and followed.

  • Standardization of the Liquid Chemical Sterilization Cycle ensures that all devices are processed in exactly the same manner.
  • Each cycle printout provides documentation on whether the parameters for liquid chemical sterilization have been met.
  • The Diagnostic Cycle and MaxPure™ Filter integrity test provides validation of system integrity.

CYCLE DESCRIPTION

The SYSTEM 1E Liquid Chemical Sterilant Processing System features two standard cycles:

  1. Liquid Chemical Sterilization Cycle
  2. Diagnostic Cycle

Refer to the SYSTEM 1E Processor Operator Manual for full processing instructions:

Liquid Chemical Sterilization Cycle

  • Used to process devices that have been properly cleaned, then visually inspected and tested for proper working condition, according to the manufacturer’s recommendations.
  • Immersible, heat-sensitive devices are placed in the processing chamber.
  • If applicable, the appropriate Quick Connect is attached to the device and the Processor is then sealed. Filtered, UV-treated water enters the chamber and mixes with the sterilant to prepare the use dilution.
  • The use dilution fills the chamber and is typically heated to 115 – 131°F (46 – 55°C) for liquid chemical sterilization.
  • The environmentally safe use dilution then drains from the chamber, and the device and chamber are rinsed with UV treated and filtered water two times.
  • Upon successful completion of the Liquid Chemical Sterilization Cycle (less than 25* minutes duration), devices are ready for immediate use.
  • * Actual cycle time may vary due to water pressure, incoming water temperature or filter status.

Diagnostic Cycle

  • Run to ensure that the MaxPure Filter and all electro-mechanical systems of the SYSTEM 1E Processor are functioning correctly.
  • The cycle consists of a series of internal tests which are performed sequentially.
  • A successful Diagnostic Cycle assures the operator that the system operates as designed for liquid chemical sterilization.
  • Failure of a Diagnostic Cycle tells the operator that the processor must not be used until the problem is corrected and a successful Diagnostic Cycle is run.
  • A Diagnostic Cycle takes approximately 14 minutes and should be run once every 24 hours.
