Lancer UK High Performance instrument decontamination

Eurotherm controls and monitors the effectiveness of medical instrument decontamination like this endoscope

Eurotherm provide smart patency control monitoring for Lancer UK Disinfectors

IN THE HEALTHCARE industry, disinfection of medical equipment is critical to the safety of patients and to the performance of the instrument. Each year, thousands of patients can become sick from infections contracted at a medical facility.

Eurotherm is helping medical facilities improve their monitoring capabilities for decontamination of equipment, and ultimately, reduce the number of illnesses and deaths.

The control monitoring system, known as the 6100A Chart Recorder, can collect and verify data to prove that all disinfection processes are 100 percent accurate and complete.

For example, an endoscope is used for non-invasive surgical procedures and requires extensive disinfection.

Lancer UK is a leading manufacturer in the field of Endoscope, Laboratory and Surgical Instrument Decontamination equipment. They are part of Getinge, the world’s leading provider of complete, ergonomical, cost-efficient solutions for effective cleaning, disinfection and decontamination in the healthcare and life science sectors. Lancer did a six-month evaluation of ABB, Endress & Hauser, and Eurotherm control monitoring systems.

Objective

Lancer wanted to improve their monitoring capabilities for decontamination of equipment, in accordance with all global regulations—one of these is the Health Technical Memorandum (HTM) for Washer Disinfectors
“All WDs (washer disinfectors) are subjected to a planned programme of tests (such as HTM ) to validate their performance, that is, to provide evidence that, when operated under the specified conditions, the WD will reliably produce cleaned and disinfected items to the standard required”
Within HTM it states that the WD should be equipped with the means to provide independent monitoring of all cycle variables.More detailed documentation about decontamination of reusable medical equipment can be viewed here – MHRA_MAC HTM

Challenges

The extreme sensitivity, complexity and high technology found with endoscopes mean that they cannot be steam sterilised or reprocessed like normal surgical instruments. Cleaning and disinfection are delicate operations. After decontamination, the equipment must be handled carefully to minimise any risk of re-contamination. Also, the Washer Disinfector has to be able to accommodate multiple makes and designs of these complex endoscopes

Detailed levels of cleaning have to be monitored and recorded :-

• the correct disinfectant temperature and exposure time per cycle
• that all channels to be irrigated with disinfectant solution do not leak or are not blocked
• the quality of the final rinse water is always in accordance with the manufacturer’s instructions

Solution

• Eurotherm 6100A Chart Recorder data monitoring and control solution adhering to HTM and EN ISO 15883 standards for their endoscope washer disinfectors. This enables full monitoring, control, traceability and validation.
• Eurotherm Data Acquisition units
• T2550 I/O to interface the endoscope patency control into the
• 6100A chart recorder – our unique offering.

Customer Benefits

• With T2550 I/O Lancer are unique in being able to interface endoscope patency control into the 6100A chart recorder. That is –

Lancer can record fluid flow testing (patency) within the channels fully compliant to HTM. A flow meter linked to a microprocessor is used to check the flow-rates within the endoscope’s channels throughout the washing and disinfection cycle. Any variation from the values registered for each endoscope during the self-learning cycle automatically triggers an alarm signal. This system can detect, for example, the partial blockage of a channel that might prevent proper washing and disinfection. A unique offering, made possible with the Eurotherm solution which acts as an independent monitor of the main control system.

• They satisfy all current and future drafted global regulations for monitoring, detailed traceability and validation with the aid of our data monitoring and control solution.
• Fitted with the Eurotherm latest independent process verification recorder and a conductivity meter enables recording and control of all critical parameters; pressure of hydraulic circuit, chemical dosing pump flows, water conductivity, time and temperature -all independently from the FC microprocessor.

Scope Controls

Decontamination washers keep patients safe by reducing the spread of infection from medical equipment.

Full traceability and compliance with a record of all data.

The Fibro-Cleaner printer prints out a ticket which provides traceability of the following data for each cycle:
cycle no, date, identification no. of the endoscope processed, program run, cycle duration, operator identification no, time of start and end of the cycle etc.
The printer ticket can also integrate the confirmation by the operator of the successful completion of the cycle. Images courtesy of Lancer UK
