What This Guide Helps With
Troubleshooting an unrecognized probe, absent pre-scan image, failed scan initiation, incomplete acquisition, or repeated inability to obtain bladder-volume results.
Step-by-Step Troubleshooting
1. Ensure Patient Safety First
Do not troubleshoot an unresolved scan-acquisition problem while the BioCon 1100 is being relied upon for a clinical bladder-volume decision.
If bladder volume is clinically urgent, provide another verified bladder scanner or alternate assessment method before continuing.
Expected: Patient care is not dependent on a device that cannot reliably acquire a scan.
Why it matters: An absent, incomplete, or unreliable scan should not be interpreted as a valid bladder-volume measurement.
If transferring the clinical need to another verified method resolves the immediate concern, continue troubleshooting only in a controlled Clinical Engineering setting.
2. Verify the Exact Failure Behavior
Power on the BioCon 1100 and determine what actually fails:
- Probe appears unavailable or unresponsive
- No live pre-scan image appears
- Scan control produces no response
- Acquisition begins but does not complete
- Progress repeatedly stops or resets
- No bladder-volume result is generated
- Failure occurs intermittently
- Hardware, maintenance, or diagnostic alert appears
Record the exact displayed message or behavior rather than documenting only “probe bad” or “will not scan.”
Expected: The failure is narrowed to probe response, pre-scan imaging, scan initiation, acquisition completion, or result generation.
Why it matters: The BioCon 1100 uses live pre-scan imaging and a 3D mechanical-sector probe acquisition process, so different symptoms may point to different parts of the scan path.
3. Verify Stable Device Power
Confirm the console starts normally and remains powered without:
- Unexpected shutdown
- Rebooting
- Display blanking
- Low-battery behavior
- Loss of response during acquisition
If operating on battery, repeat the controlled test with the approved external power supply when appropriate.
If already on external power:
- Verify the outlet with a known-good tester or device
- Inspect the AC cord and adapter
- Reseat accessible power connections
- Check for damaged plugs, strain relief, or intermittent connections
Expected: The console remains stable through startup, pre-scan, and attempted acquisition.
If resolved: Document the power-related cause and stop.
4. Inspect the Probe Externally
Remove the device from patient use and inspect the complete accessible probe assembly for:
- Cracked housing
- Damaged probe head
- Evidence of impact or dropping
- Cable cuts or crushing
- Kinks near strain-relief points
- Loose housing components
- Fluid intrusion
- Dried gel or contamination
- Unusual heat
- Unusual sound during attempted scanning
Do not continue using a probe with visible structural damage or suspected fluid intrusion.
Expected: The probe and cable are intact, clean, dry, and free of obvious mechanical damage.
If damage is found: Remove the device from service and escalate for repair evaluation.
5. Clean and Dry the Probe Appropriately
Inspect the probe head for dried ultrasound gel or residue that could interfere with acoustic coupling or make troubleshooting inconsistent.
Clean and disinfect according to approved facility and manufacturer-compatible procedures. Ensure the probe is dry before retesting.
Do not flood recessed areas, cracks, or crevices with cleaning solution, and do not immerse portions of the probe not approved for immersion.
Expected: The accessible probe surfaces are clean, dry, and free of residue.
If resolved: Document contamination or cleaning-related interference and stop.
6. Check the Accessible Probe Connection
With the device safely removed from clinical use and powered down as appropriate:
- Inspect the accessible probe connection
- Check for incomplete seating
- Look for bent, damaged, contaminated, or recessed contacts where externally visible
- Check the connector shell for cracks or looseness
- Reseat the connector securely if it is designed for routine external connection
Do not force a keyed connector and do not open the console or probe housing.
Expected: The probe connection is fully seated and mechanically secure.
If resolved: Document a loose or poorly seated probe connection and stop.
7. Restart the System and Recheck Recognition
After verifying the probe connection:
- Power the device down normally.
- Allow the shutdown process to complete.
- Restore power.
- Observe startup behavior.
- Check whether the probe and scanning functions are available.
Watch for:
- Diagnostic warning
- Hardware alert
- Maintenance indication
- Probe-related message
- Abnormal startup delay
Expected: The scanner completes startup and permits normal pre-scan operation.
If resolved: Document that probe communication or scan availability returned after reseating and controlled restart, then complete functional verification before return to service.
8. Test Pre-Scan Operation
From a normal test state, initiate the pre-scan function and observe whether a live ultrasound image appears.
Confirm whether:
- The image starts promptly
- The image updates continuously
- The image freezes unexpectedly
- The display remains blank
- The function exits back to the home screen
- An error or diagnostic message appears
Expected: A stable live pre-scan image is displayed.
If no live image appears: Continue troubleshooting; do not assume a complete scan will be reliable.
9. Verify Scan-Control Response
Operate the normal scan control and confirm that the device responds consistently.
Check for:
- No response to the scan control
- Delayed response
- Intermittent response
- Response only when the probe or cable is moved
- Pre-scan functioning but full acquisition failing
Do not repeatedly flex or manipulate a suspect cable to force operation.
Expected: The scan command is recognized consistently without cable manipulation.
If operation changes with cable position: Remove the device from service because an intermittent probe or cable fault is likely.
10. Rule Out an Acoustic-Coupling Problem
Using an approved controlled test method, verify adequate ultrasound coupling.
Check for:
- Sufficient ultrasound gel
- No large air gaps
- Full probe-head contact
- Correct probe orientation
- Stable probe placement
Air between the probe and test surface can prevent useful ultrasound transmission and mimic an acquisition problem.
Expected: A usable ultrasound image is present during pre-scan.
If resolved: Document inadequate gel, poor contact, or positioning as the cause and stop.
11. Confirm Appropriate Scan Setup
Verify the selected scan or patient configuration is appropriate for the controlled test being performed.
Check for incorrect selections that could contribute to failed targeting or confusing results.
Return only user-accessible settings to known appropriate values. Do not alter hidden service parameters.
Expected: The scanner is configured appropriately for the test condition.
If resolved: Document the incorrect setup and resulting corrective action.
12. Perform a Controlled Acquisition Test
Using an approved bladder phantom or other manufacturer-appropriate test method, attempt a complete scan.
Observe whether the system:
- Enters pre-scan
- Produces a usable image
- Accepts the scan command
- Begins acquisition
- Completes acquisition
- Generates a volume result
- Repeats consistently
The BioCon 1100 performs a multi-plane 3D acquisition to calculate bladder volume, so a failure after pre-scan may represent a different fault than total loss of probe imaging.
Expected: The scan completes and produces a repeatable result appropriate for the approved test object.
If resolved: Complete required post-repair or functional verification and stop.
13. Check for Mechanical or Intermittent Probe Behavior
During controlled testing, listen and observe for abnormal behavior from the probe during acquisition.
Check for:
- Acquisition starting and stopping
- Repeated incomplete scan cycles
- Abnormal clicking or grinding
- Failure only after the probe is moved
- Intermittent live imaging
- Failure that worsens after repeated scans
Do not open the probe or attempt internal mechanical adjustment.
Expected: Probe operation remains consistent and acquisition completes without abnormal behavior.
If abnormal mechanical behavior is present: Remove from service and escalate for bench evaluation.
14. Review Built-In Diagnostic Indications
Document any hardware or maintenance alert displayed by the BioCon 1100.
Where normal Clinical Engineering access permits, review available user-facing diagnostic or status information without changing protected service parameters.
Record:
- Exact message
- When it appears
- Whether it clears after restart
- Whether it returns during scanning
- Whether it follows a specific probe or console condition
Expected: No persistent hardware or maintenance fault remains.
If a diagnostic indication persists: Stop external troubleshooting and escalate.
15. Compare With Known-Good Components Only When Approved
If your facility has manufacturer-compatible equipment and component substitution is permitted:
- Test with a verified compatible known-good probe, or
- Test the suspect probe on an approved compatible known-good system
Perform substitution only when connector compatibility, configuration, and institutional procedures are confirmed.
Expected: The fault follows either the probe assembly or the console.
Interpretation:
- Failure follows probe → suspect probe/cable assembly
- Known-good probe also fails → suspect console-side acquisition or communication fault
- Suspect probe works normally elsewhere → investigate console connection or internal system fault
If the fault is isolated: Document the result and send the affected component or device for appropriate repair.
16. Verify Repeated Performance Before Return to Service
After any successful corrective action, perform repeated controlled scans.
Confirm:
- Stable startup
- Normal probe availability
- Reliable pre-scan image
- Consistent scan-control response
- Complete acquisition
- Repeatable results
- No hardware or maintenance alerts
- No intermittent behavior with normal handling
Use an approved phantom or facility verification method when available.
Expected: The device completes repeated scans reliably.
If the fault recurs even once: Do not return the scanner to clinical service.
If the Problem Persists
If power, external probe condition, cleaning, accessible connections, startup, coupling, settings, scan controls, and controlled acquisition testing have been ruled out, the problem is likely beyond routine external troubleshooting.
Possible remaining faults may involve:
- Probe transducer assembly
- Probe cable or intermittent conductor
- Mechanical scan mechanism
- Probe communication circuitry
- Console-side probe interface
- Acquisition electronics
- Internal power delivery to the probe
- Software or control-system fault
The device should be:
- Removed from service
- Labeled Out of Service
- Sent for authorized repair or qualified bench evaluation
Do not open the probe, adjust the internal scanning mechanism, or perform unsupported board-level repair.
Knowing when to stop is proper troubleshooting.
Clinical Use Tip
Do not troubleshoot a failed bladder scan repeatedly on an active patient while clinical decisions depend on the result. Move the clinical need to another verified scanner or assessment method first.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Clinical staff reported the Medline BioCon 1100 would not consistently recognize probe operation or complete a bladder scan."
Cause
What was observed during troubleshooting.
Example:
"Inspection found the external probe connection incompletely seated, resulting in intermittent pre-scan imaging and failed scan acquisition."
Resolution
What action was taken.
Example:
"Reseated and secured the probe connection, restarted the scanner, and verified repeated successful pre-scan and complete acquisition testing with the approved test method."
Helpful Details to Include (If Known)
- Outlet tested
- External power supply tested
- Battery versus AC behavior
- Probe recognition behavior
- Probe cable condition
- Probe head condition
- Probe connection reseated
- Live pre-scan image present or absent
- Scan control response
- Acquisition progress behavior

Final Thought
A BioCon 1100 scan failure should be approached logically: protect the patient first, verify power and probe condition, confirm live imaging and acquisition behavior, then escalate persistent faults appropriately. Clear CCR documentation preserves the evidence needed for safe repair decisions and future trend analysis.
That is successful troubleshooting.
