What This Guide Helps With
This guide helps troubleshoot the ICU Medical CADD-Solis high-priority alarm Disposable detached while delivering. This alarm indicates the pump detected that the disposable cassette or set became detached, unlatched, or improperly secured while therapy was being delivered.
The latch/lock sensor circuit allows the pump microprocessor to stop delivery and alarm if the set is unlatched during delivery. Because medication or fluid delivery may be interrupted, this alarm should be treated as a patient care concern until the setup is corrected and therapy status is verified.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- Notify clinical staff immediately if the alarm occurs during active therapy.
- Stop or pause therapy as clinically appropriate.
- Verify whether the patient received the expected infusion or if delivery was interrupted.
- Do not resume infusion until the cassette, disposable set, latch, and lock status are confirmed safe.
- Use another pump or alternate approved delivery method if therapy must continue and the alarm cannot be cleared safely.
Verify the Reported Alarm
- Confirm the alarm message displayed is Disposable detached while delivering.
- Confirm whether the alarm occurred during active delivery, after cassette handling, after pump movement, or after the door/latch area was touched.
- Ask staff whether the disposable was recently installed, replaced, adjusted, or bumped.
- Check whether the pump stopped delivery when the alarm occurred.
Inspect the Disposable Cassette or Set Attachment
- Inspect the cassette or disposable set for proper seating on the pump.
- Confirm the cassette is fully attached and not partially lifted, tilted, or loose.
- Look for tubing tension pulling on the disposable.
- Check for cracked, damaged, warped, or contaminated cassette surfaces that could prevent secure attachment.
- Replace the disposable if there is any visible damage or if it does not seat securely.
Check the Latch and Lock Status
- Open and close the latch according to facility and manufacturer procedure.
- Confirm the latch fully engages and does not feel loose, obstructed, or partially closed.
- Verify the pump is locked if required for the therapy setup.
- Check for debris, dried medication, damage, or obstruction around the latch area that could prevent proper detection.
- Do not force the latch or continue use if the latch or lock mechanism feels damaged.
Reconnect or Replace the Disposable
- Remove the disposable set if needed and reconnect it carefully.
- Use a new compatible disposable if the existing one does not attach securely or the alarm returns.
- Confirm the disposable is the correct type for the pump and therapy.
- Make sure tubing is routed to avoid pulling on the cassette during patient movement or pump transport.
Confirm Operation Before Returning to Use
- Confirm the alarm clears after the disposable is properly attached and latched.
- Verify the pump recognizes the disposable and allows therapy setup to continue.
- Have clinical staff confirm the therapy settings, medication, volume, and delivery status before restarting infusion.
- Observe the pump briefly after restarting to confirm the alarm does not immediately return.
If the Problem Persists
If the alarm continues after the disposable has been reattached or replaced, external causes such as incorrect cassette seating, disposable damage, latch position, tubing tension, and lock status have been ruled out.
Remove the device from service, label it Out of Service, and send it for repair or bench evaluation. A recurring alarm may indicate a latch, lock, sensor, or pump detection circuit issue that should not be ignored.
Clinical Use Tip
Never troubleshoot on an active patient if doing so could interrupt therapy, disturb the infusion setup, or create medication delivery risk. Move the patient to a backup pump or approved alternate delivery method first, then evaluate the CADD-Solis pump when it is safe to do so.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"ICU Medical CADD-Solis pump displayed high-priority alarm Disposable detached while delivering during active infusion."
Cause
What was observed during troubleshooting.
Example:
"Disposable cassette was not fully seated and latch status was not secure. Existing disposable was inspected and replaced."
Resolution
What action was taken.
Example:
"Replaced disposable set, confirmed cassette fully attached, verified latch and lock status, alarm cleared, and pump was returned to clinical staff for therapy verification."
Helpful Details to Include (If Known)
- Alarm behavior
- Accessories swapped
- Power behavior
- Environmental factors
- Indicator lights
- Final device status
Final Thought
A disposable detached alarm during delivery should be handled as both a pump issue and a therapy interruption concern. Start with patient safety, confirm the cassette and latch externally, replace the disposable when needed, and escalate the pump if the alarm returns after proper setup.
That is successful troubleshooting.
