Maintenance Features

Battery Management

The Mini Rythmic™ PN+ uses a non-rechargeable 9V alkaline internal battery. A low battery warning will appear when replacement is needed. The battery life varies depending on the infusion rate:

8.5 hours minimum at 150ml/hr
8.5 hours minimum at 200ml/hr
8 hours minimum at 250ml/hr
7.5 hours minimum at 300ml/hr

External Battery Pack

The External Battery Pack should always be connected to the pump during use, including when priming the giving set. A fully charged external battery pack provides extended operation:

21 hours minimum at 150ml/hr
20 hours minimum at 200ml/hr
19 hours minimum at 250ml/hr
18 hours minimum at 300ml/hr

If a low external battery warning appears, plug the External Battery Pack into the mains supply. The pump can continue infusing while the external battery pack is charging.

IP Connect Pack

The IP Connect pack is used in conjunction with the discharging hospital. It charges similarly to the External Battery Pack and has comparable battery life. Full training on its use is provided. An on-screen icon confirms connection.

Alarms and Warnings

The pump is equipped with several alarms to ensure patient safety and proper operation:

Warnings: The pump continues to function, but an alarm sounds intermittently. Press the soft key below the bell sign to silence it.
Near End of Infusion: The pump alarms when nearing the end of the VTBI (preset at 20 minutes, configurable to volume remaining, time remaining, or off).
Low External Battery Pack: An alarm sounds 40 minutes before the external battery is depleted. The internal battery automatically takes over. Press the bell sign twice to silence the alarm. Replace with a charged external battery pack or connect to mains supply.
Low Internal Battery: An alarm sounds 40 minutes before the internal battery is depleted. Press the bell sign twice to silence the alarm. Connect to an External Battery Pack or mains supply and replace the internal battery when available. Ensure the internal battery indicator shows 2 or more blocks.
Keep Vein Open (KVO): An alarm sounds when the pump enters KVO mode. Press enter button (4) to silence. KVO only functions if the bag volume is greater than the VTBI.
Pump Unattended: An intermittent alarm sounds if the pump is on hold or no button has been pressed for 1 hour. Press enter button (4) to confirm settings and start infusion.
Downstream Occlusion: Indicates a problem between the pump and the patient. The pump alarms and stops. Press enter button (4) to silence. Rectify the problem, and the pump will automatically restart.
