What This Guide Helps With
This guide addresses the alarm: Door opened! Infusion stopped! Close Door. This condition occurs when the cassette door is opened or not fully latched during infusion, immediately stopping medication delivery and requiring proper closure before therapy can resume.
Step-by-Step Troubleshooting
1. Ensure Patient Safety First
- Immediately assess the patient and infusion status
- Transfer infusion to a backup pump if therapy is interrupted
- Do not continue using the device until the issue is resolved
2. Verify the Reported Alarm and Behavior
- Confirm the alarm message is displayed on the screen
- Observe if the alarm occurred during active infusion
- Check if infusion stopped immediately
- Inspect whether the cassette door is open or loose
3. Check Cassette Door Position (Most Common Cause)
- Ensure the cassette door is fully closed
- Listen or feel for a secure latch click
- Confirm there is no partial closure
4. Inspect Cassette Installation
- Open the door and check cassette placement
- Ensure the cassette is properly seated
- Verify tubing is not pinched or obstructing closure
- Reinsert cassette and close the door firmly
5. Check for Obstructions or Damage
- Inspect for debris, dried fluid, or residue around the latch
- Ensure hinges and latch mechanism move freely
- Verify the door closes without resistance
6. Test Door Sensor Function
- Close the door with cassette installed
- Restart infusion
- Gently apply pressure to confirm stability
- Observe if the alarm clears and remains cleared
7. Swap Cassette (If Needed)
- Replace with a known-good cassette
- Reattempt setup and infusion
- Confirm whether the alarm resolves
If the Problem Persists
If the alarm continues despite proper door closure and cassette replacement, external causes have been ruled out. This indicates a likely failure of the door sensor or latch mechanism.
- Remove the device from service
- Label as Out of Service
- Send for repair or bench evaluation
Clinical Use Tip
Never troubleshoot door or cassette issues on an active patient. Always move the patient to a backup infusion device before performing checks.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Alarm 'Door opened! Infusion stopped! Close Door' occurred during infusion and medication delivery stopped."
Cause
What was observed during troubleshooting.
Example:
"Cassette door not fully latched due to improper cassette seating."
Resolution
What action was taken.
Example:
"Reseated cassette and fully closed door; verified alarm cleared and infusion resumed. Pump returned to service."
Helpful Details to Include (If Known)
- Alarm behavior
- Accessories swapped
- Power behavior
- Environmental factors
- Indicator lights
- Final device status
Final Thought
Door-related alarms are safety-critical and immediately stop infusion. Always verify full mechanical closure and proper cassette seating before suspecting internal failure. Escalate appropriately when the issue cannot be resolved externally.
That is successful troubleshooting.
