                       PROBE COMPONENT OF COMMON FAILURES AND SOLUTIONS

LIST OF COMMON FAILURES

• CRYSTAL FAILURE
• CABLE LEAKAGE
• LENS FAILURE
• SHEATH FAILURE
• CASE FAILURE

CRYSTAL 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
• Interference 
• 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
• Fracture
• Revealing the inside line
• Shielding layer damage
• Break

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.

CABLE BREAKAGE ULTRASOUND PROBE

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

SHEATH FAILURE

• 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

BROKEN ULTRASOUND PROBE CABLE

CASING FAILURE

• 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.
