What This Guide Helps With
This guide addresses situations where the Kangaroo ePump touchscreen or keypad:
- Does not respond to user input
- Responds intermittently or erratically
- Registers incorrect selections or “ghost” inputs
The focus is on external, easily verifiable causes first—such as power, connections, and contamination—before assuming internal electronics failure.
Step-by-Step Troubleshooting
Verify Power Source
- Ensure the pump is properly plugged into a verified working outlet or fully charged battery.
- A weak or fluctuating power source can cause unresponsive or erratic keypad/touchscreen behavior.
Inspect for Physical Obstructions or Contamination
- Check the screen and keypad for moisture, dirt, or residue.
- Clean gently with a lint-free cloth and approved cleaning solution.
- Liquid spills or excessive debris can block touch response.
Check Protective Covers or Cases
- If the pump has a protective silicone or plastic overlay, remove it and test the keypad.
- Some covers can interfere with proper touch registration.
Perform a Soft Reset
- Turn the pump off, wait 10–15 seconds, then turn it back on.
- This can reset the touchscreen controller and clear minor software glitches.
Test All Buttons and Touch Areas
- Press each button and touch multiple areas of the screen.
- Confirm if the unresponsiveness is localized or affects the entire keypad.
Inspect Connectors and Cables
- Check the ribbon cable or connector between the keypad/touchscreen and main board (if accessible externally).
- Ensure it is seated properly and not damaged.
If the Problem Persists
External causes have been ruled out, and the issue is likely internal electronics or touchscreen controller failure.
- Remove the device from service
- Label as Out of Service
- Send for manufacturer repair or internal bench evaluation
Knowing when to escalate is proper troubleshooting and ensures patient safety.
Clinical Use Tip
- Never attempt to troubleshoot on a patient actively receiving feeding.
- Switch the patient to a backup pump or alternative feeding method before troubleshooting.
- Ensure all device manipulations are done in a safe environment to avoid accidental infusion.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
“Pump touchscreen not responding, unable to start feeding.”
Cause
What was observed during troubleshooting.
Example:
“Screen unresponsive after inspection; no visible damage or contamination; soft reset did not restore function.”
Resolution
What action was taken.
Example:
“Pump removed from service, labeled Out of Service, sent for manufacturer evaluation.”
Helpful Details to Include
- Verify if the issue occurs on battery or AC power
- Note any screen flickering or ghost inputs
- Record if protective overlays were present
- Document if soft reset temporarily restored partial functionality
Final Thought
Patient safety and proper device function are paramount. Use logical troubleshooting steps, check external factors first, and escalate appropriately. Clear documentation ensures continuity of care and compliance with hospital procedures.
That is successful troubleshooting.
