MPS 3 System – System Maintenance
12.1.3.5.Changing the Water in the System
The water in the circulation system must be changed every 7 days. After changing,
add 25 ml of 3% Hydrogen Peroxide to the Hypothermic Reservoir and circulate to
inhibit microbial growth. After each use of the MPS 3 System, drain the Hypothermic
Reservoir to its drain spout, add an additional 25 ml of 3% hydrogen peroxide, to
compensate for dilution of melted ice, and circulate to ensure distribution throughout
the water circulation system.
Note: To ensure the hydrogen peroxide concentration is maintained above 100ppm
conduct daily monitoring of the concentration follows:
•
Drain 100 ml of water from the circulation system drain valve and discard.
•
Drain a minimum volume of 5 ml from the drain valve into a sterile sample
container for measurement and then discard the drain/adapter assembly.
•
Test the concentration of hydrogen peroxide using a peroxide test strip (The
MPS 3 disinfection procedure was validated using Indigo Instruments High
Level Peroxide Test Strip 33815-P400). Refer to test strip Manufacturer’s IFU for
instruction on using test strip.
•
If the H
2
O
2
concentration falls below 100ppm, repeat the Disinfection process.
12.1.4.System Controller Cleaning
The Controller display panel has a special coating that can be ruined by strong
cleaners. Do not spray water or other liquids directly on the screen or the case.
Protect the Controller from spills and dripping OR solutions. Prevent any kind of
adhesive application to the surface of the display panel.
Do not use alcohol wipes or antimicrobial wipes to clean the display panel as it may
damage the screen.
If the Controller does not respond to the operators touch or is visibly soiled, the
display panel needs cleaning. Pause the screen to avoid inadvertent parameter
changes. Clean the display panel with only a damp soft cloth to prevent scratching.
Clean spills immediately after the occurrence of the spill.
Clean the case, Power / Data cable and mounting arm with antimicrobial wipes.
