5.3 REPLACING ULTRASONIC CONTACT CREAM
During londer procedures, it is possible that the ultrasonic contact cream might dry
out, which can impair the results of the flow meter. For this reason, the ultrasonic
contact cream must be renewed every 48 hours or as soon as the error message
[SIG!] appears.
Ensure that this procedure is performed in less than 60 seconds.
1 Reduce the speed to the minimum (1500 rpm) to prevent a reverse flow
(drainage) of the patient’s blood. The minimum speed is the speed at which the
patient and line pressure are exceeded.
2 Clamp the outlet tube of the ROTAFLOW Centrifugal Pump to prevent a
reverse flow.
3 Reduce the speed to 0 rpm.
4 Open the lock on the ROTAFLOW Drive.
5 Remove the ROTAFLOW Centrifugal Pump from the ROTAFLOW Drive.
WARNING! Risk of serious injury or death with failure to observe this
procedure.
During this procedure, the blood flow will be interrupted and supply to the patient
will cease.
„ This procedure should therefore be performed as quickly as possible.
„ This procedure may only be performed by qualified staff.
„ Only use ultrasonic contact cream, which is listed as an accessory.

Note
The error message [SIG!] indicates an error in flow measurement. The
ROTAFLOW Centrifugal Pump continues to function nevertheless.
