8.5 Operation of the CentriMag
TM
Circulatory Support System On Internal
Console Battery Power
If there is a need to operate the System for a longer period than the Console’s internal
battery will allow, a backup Console must be used. Refer to Table 14 for appropriate
times.
The following System components are required for the operation of the System on
Console Battery Power:
1) 1 main Console
2) 1 backup Console
3) Two Motors (one Motor will be connected to the main Console and the other
connected to the backup Console)
4) 1 main and 1 backup Flow Probe.
5) Mag Monitor (optional)
8.5.1 Planning for Battery Support
The duration the System can be operated without mains power is limited by the available
battery charge. Careful planning should be taken before extended duration battery support
is initiated, and the duration of battery support should be kept to a minimum. The total
duration should be planned so that only the internal battery of the main Console is used.
The battery in the backup Console should only serve as a reserve for emergency
situations or in instances where exact battery support time cannot be estimated
beforehand.
The Console should never be connected to ambulance-derived AC mains power. All
Consoles need to have fully charged internal batteries before mains power is
disconnected from the System. In the event the duration of the patient transit is longer
than expected, operate the CentriMag Motor and Pump with the backup Console.
8.5.2 Changing from the Main to the backup Console
When the charge level of the main Console’s internal battery reaches a pre-set minimum
level, the LOW BATTERY alert is activated, accompanied by an audio tone. In this
instance, the main Console must be replaced with a backup Console. In the latter case,
follow the steps in the Switching to Backup Hardware section.
8.5.3 Battery Support Time at Various Operating Levels
Estimated battery runtimes of the System at various operating levels while on internal
Console battery support are listed in the table below.
