                       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.
