What This Guide Helps With
This guide assists Clinical Engineering in troubleshooting B. Braun Space Infusion Pumps that fail to charge properly or display rapid battery depletion. Common causes are often external, such as docking issues, power supply problems, or battery seating errors, rather than internal battery failure.
Step-by-Step Troubleshooting
Verify Power Source
- Ensure the docking station or wall outlet is supplying power.
- Test the outlet with a known working device.
- Reason: A faulty outlet or unplugged docking station is a common cause of battery issues.
Inspect Docking Station Connection
- Remove the pump and reseat it on the docking station.
- Check for debris or misalignment in the contacts.
- Reason: Poor contact prevents charging even if the pump and station appear connected.
Check Power Cable and Adapters
- Inspect cables for frays, kinks, or damage.
- Swap with a verified working cable if available.
- Reason: Damaged power cords can reduce voltage to the pump, slowing or preventing charging.
Confirm Battery Seating
- Remove the battery (if removable) and reinstall, ensuring it clicks into place.
- Reason: A loosely seated battery may show charge errors.
Review Pump Indicators
- Observe battery icons or status LEDs when on dock.
- Look for flashing patterns indicating error codes.
- Reason: B. Braun pumps display diagnostic info via LEDs; this guides next steps.
Perform Battery Calibration / Pump Reset
- If the pump supports a soft reset or battery recalibration, follow manufacturer guidelines.
- Reason: Sometimes the pump misreads battery state, showing rapid depletion incorrectly.
Swap Battery (if available)
- Replace with a known working battery.
- Reason: Confirms if issue is pump-related or battery-specific.
If the Problem Persists
External factors have been ruled out. The battery or internal charging circuitry may be failing.
- Remove pump from service.
- Label “Out of Service.”
- Send for manufacturer repair or bench evaluation.
Knowing when to stop is proper troubleshooting and ensures patient safety.
Clinical Use Tip
Never attempt patient infusion with a pump showing charging errors.
Move the patient to another verified pump before troubleshooting.
Only perform troubleshooting when the device is not actively infusing.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
“Pump battery will not charge and drains rapidly; pump disconnected from dock.”
Cause
What was observed during troubleshooting.
Example:
Verified power source, docking station, and cables; battery correctly seated. Pump battery continues to deplete quickly, suggesting possible internal battery or charging circuit failure.
Resolution
What action was taken.
Example:
Pump removed from service, labeled Out of Service, and sent to biomedical repair for evaluation.
Helpful Details to Include
- Outlet tested with known device
- Docking station verified
- Cables inspected/swapped
- LED/battery indicator behavior
- Any error codes displayed
- Final device status: Out of Service
Final Thought
Patient safety and logical troubleshooting go hand-in-hand. Start with external and easily verified checks, escalate appropriately, and document all findings. This prevents unnecessary downtime, ensures accurate diagnosis, and maintains compliance.
That is successful troubleshooting.
