PROBE COMPONENT OF COMMON FAILURES AND SOLUTIONS
LIST OF COMMON FAILURES
- CRYSTAL FAILURE
- CABLE LEAKAGE
- LENS FAILURE
- SHEATH FAILURE
- CASE FAILURE
- After long-term use can be caused the crystal of natural aging
- Touch hit will make probe crystal damage
CRYSTAL FAILURE PROBE SHOWS
- Image has dark
- Black bars
- Defects such as blind area
- Affecting the quality of diagnosis
CRYSTAL FAULT SOLUTIONS
- This kind of failure is caused by ultrasound probe wafer short circuit.
- Which can judged by measuring the power supply voltage of the chip.
- If the chip set has a short circuit,Replace the corresponding chip.
- It makes the probe to restore the previous feature.
|DAMAGED CRYSTAL ULTRASOUND PROBE
CABLE LEAKAGE FAILURE
- Ultrasound probe cable is adopted by high quality of high muti-fiber sheilded cable and wire.
- The bending and torsion of the cable makes outside of reserve cable insulating layer will be,
- Broken skin
- Revealing the inside line
- Shielding layer damage
CABLE LEAKAGE FAULT SOLUTION
- Due to probe affected by external force or wrong operates,the probe was not properly placed for a long time.
- Open the outer leather,lateral horizontally gashing the total shielding wire.
- Pick out the deep crack line.
- Welding is completed with transparent tape around one layer.
- Use a multimeter to measure whether it turned on.
- This wire shielding will be connected and wrapped the tape.
- To connect the wire shielding and tie up good adhesive tape.
- After the outermost shielded wire welding,fixed outer holster with high voltage margin plastic tape.
- In this way,you can continue to use probe for a long time.
LENS OF FAILURES
- Acoustic lens is gelatinous professional substance that ultrasound probe contacts the upper body.
- The acoustic lens can cause wear and tear,scratch,crack,corrosion,degumming,blister and other damage after used for long-time.
LENS OF FAULT SOLUTIONS
- With liquid silicone inject in degumming and expelled bubbles.
- With gauze tied the probe for 24 hours before deregulation.
- The fault disappears and the probe returns to normal.
- The failure was caused by unglued match between Acoustic lens and matching layer.
- In dealing with this kind of failure,using liquid silicone rubber for the probe acoustic lens repair materials.
|LAYER DAMAGE ULTRASOUND PROBE
- Ultrasound probe sheath is ultrasound probe and cable joint reinforcement effect of slab.
- Ultrasound probe sheath important is to prevent the cable right-angle fold the pressure.
- Long-term use can make sheath fracture,falloff and missing,cable broken.
- It also affects the image
- Shell can be cracked and aged if ultrasound probe for long term use.
- Due to human factors such as throwing,hitting and deformation.
- The quality of the probe shielding enclosure will cause the image unclear.
- There will be serious when the induced current from the front,threatening the patient's body.
|CASE DAMAGED ULTRASOUND PROBE
SHEATH AND SHELL DAMAGE SOLUTION
- Handle with care.
- Need to replace the damaged components.
