Signostics Signos Personal Ultrasound
Signostics · Model Signos Personal Ultrasound
Increase clinical efficiency Improve patient outcomes and reduce risks associated with bladder catheterization, paracentesis, thoracentesis, wound management and fetal presentation assessment. Portable and affordable The size of a PDA, the Signos is the world’s smallest ultrasound system weighing less than one pound (320 grams), and being significantly cheaper than conventional ultrasound systems it is also the most affordable. With a sleep time of up to 14 days and the ability to power up in less than one second from sleep mode, the Signos is available wherever and whenever users need it. Image storage Using the included microSD card can save up to 10,000 high resolution images on the Signos. And with the free SigViewer Software users can quickly and easily upload data and images to their computers for reports, archiving, printing or email.
Key tips
- ·Never bypass a radiation interlock to "just get the image" - this is one of the few true zero-tolerance rules in BMET work.
- ·Trend image-quality phantom results over time - drift shows up before an outright failure does.
- ·Portable/mobile units take real physical abuse from transport - check wheel locks and cable strain reliefs more often than fixed units.
Typical Failure Modes
Failure patterns typical of this equipment class - general BMET reference, not verified against this exact unit's own service history unless flagged. Severity is a category-level estimate.
Transducer element failure
MediumSymptoms: Dropout, dead elements, image banding.
Root cause: Element delamination or cable damage from repeated use.
Transducer cable / connector wear
MediumSymptoms: Intermittent image loss, connector-wiggle artifact.
Root cause: Repeated flexing and connector strain.
Recon / system software hang
LowSymptoms: Frozen console, acquisition timeout.
Root cause: Workstation or storage degradation.
Display panel degradation
LowSymptoms: Dim image, color shift, dead pixels.
Root cause: Backlight or LCD panel aging.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Daily QC per modality: image-quality phantom test
- ·Tube and detector inspection
- ·Annual state-required radiation safety survey
- ·Vendor-scheduled preventive maintenance
Troubleshooting Approach
A structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Transducer element failure
- Confirm the presentation - typically dropout, dead elements, image banding - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: element delamination or cable damage from repeated use.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the ultrasound transducer / probe per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.
