What This Guide Helps With
This guide addresses situations where the Hillrom Centrella Smart+ bed touchscreen becomes unresponsive or intermittently fails to register inputs. Symptoms may include:
- No response when pressing touchscreen buttons
- Bed functions not activating via touchscreen
- Intermittent freezing or delayed response
- Alarms or notifications cannot be acknowledged from the touchscreen
The focus is on checking external factors, connections, and safe troubleshooting before assuming internal touchscreen failure.
Step-by-Step Troubleshooting
Verify Bed Power
- Ensure the bed is plugged into a working outlet and turned on.
- Observe if power indicators illuminate; a powered touchscreen cannot function without bed power.
Check Battery Status (if applicable)
- Some beds rely on internal batteries for touchscreen function.
- Confirm battery charge level; low battery may prevent touchscreen response.
Inspect Touchscreen Surface
- Clean the touchscreen with a soft, lint-free cloth and mild disinfectant.
- Remove any protective films, moisture, or debris that could interfere with touch recognition.
Confirm Connections
- Verify that all visible cables connecting the touchscreen to the bed’s main control unit are securely seated.
- Look for loose connectors, bent pins, or damaged cables.
Perform a Bed Reset
- If safe, power cycle the bed: turn off, wait 30 seconds, then turn back on.
- This can clear minor software glitches affecting the touchscreen.
Observe for Software Errors
- Check for error codes on the bed display or any indicator lights.
- Document any codes for service escalation if needed.
Test Alternate Control (if available)
- Use handset or side controls to verify if bed functions respond.
- If side controls work but touchscreen does not, issue is isolated to the touchscreen interface.
If the Problem Persists
External checks (power, cables, cleaning, reset) have been completed. The touchscreen likely has an internal failure (e.g., digitizer, controller board).
- Remove the bed from service
- Label as Out of Service
- Send for repair or bench evaluation
Knowing when to escalate prevents unsafe attempts at internal repair.
Clinical Use Tip
- Do not attempt touchscreen troubleshooting while a patient is in bed and dependent on motor functions.
- Move patient to another bed before performing checks.
- Ensure alarms and safety functions remain active via side controls or nurse call system.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
“Touchscreen unresponsive; buttons do not register inputs.”
Cause
What was observed during troubleshooting.
Example:
“Bed powers on; side controls functional; touchscreen remains unresponsive.”
Resolution
What action was taken.
Example:
“Performed cleaning, verified power and connections, performed reset; no change. Bed removed from service and sent for repair.”
Helpful Details to Include
- Power indicator status
- Battery charge level
- Cables inspected and re-seated
- Touchscreen cleaned and dried
- Reset performed
- Alternate control functionality verified
Final Thought
Patient safety and proper escalation are paramount. Logical, stepwise troubleshooting reduces risk of error and ensures timely repair. Documenting each step protects both staff and equipment.
That is successful troubleshooting.
