1.2.2 MAGNETIC UNCOUPLING
WARNING!
Magnetic uncoupling can be identified by a decrease in the flow rate and a
humming sound.
If magnetic uncoupling occurs, proceed as follows:
Disable the flow regulation immediately (
Clamp the tube to prevent a reverse flow.
Turn the speed to zero.
Once the ROTAFLOW Centrifugal Pump stops, increase the speed and open
the tube clamp simultaneously.
If magnetic uncoupling occurs again, use the ROTAFLOW Emergency Drive.
If it continues to occur, install a new ROTAFLOW Centrifugal Pump.
1.2.3 EXTERNAL DEVICES
WARNING!
If you are using the ROTAFLOW System with other medical devices, check
the total leakage currents.
Check that all devices comply with IEC 60601-1.
Check that all devices connected to the digital interface of the ROTAFLOW
System satisfy the IEC specifications (IEC 60950 for data processing
equipment located more than 1.5 meters from the operating table and
IEC 60601 for data processing equipment within 1.5 meters of other medical
devices).
1.2.4 MEMBRANE OXYGENATOR
Variations in pressure in a microporous membrane oxygenator (following an
abrupt fall in the arterial flow) may cause gas microemboli if the blood pressure
falls below the gas pressure.
WARNING!
Monitor the pressure in the arterial tube system.
Adjust the pump so that the pressure in the blood flow through the oxygenator
is always higher than the gas pressure.
