The maintenance of damaged cables for animal B-ultrasound probes uses high-quality multi-core high shielding cables with exquisite workmanship. The wires inside the cables are tight, with hundreds of wires, as thick as hair. Due to the multi-directional use of Veterinary ultrasound probes, the bending and twisting of cables can cause the insulation layer of the outer protection zone of the cable to break, expose the signal lines inside, and the shielding layer to be damaged or disconnected, resulting in interference ripples and defects in the image.

Fault phenomenon: When the animal B-ultrasound shows severe interference with the display image, snowflake like light spots appear on the full screen, and the brightness adjustment fails. Analysis and Maintenance: Due to external forces affecting the veterinary ultrasound probe or incorrect use by the operator, improper placement of the probe for a long time resulted in wire breakage inside the cable. Open the outer leather cover, cut the overall shielding wire horizontally, pick out the cracked wire, weld it, wrap it with a layer of transparent tape, measure its conductivity with a multimeter, and after conductivity, connect the shielding of this wire and wrap it with tape. If multiple fractures occur, the method is the same as above. After testing the machine and everything was normal, the outer shielding wire of * * * was welded and the outer sheath was fixed with high-voltage plastic tape. It has been used well for more than a year without any further malfunctions.

Repair of crystal damage of animal B-ultrasound probe, fault phenomenon: The image detected by animal B-ultrasound contains black shadows and black stripe interference. Analysis and Maintenance: Most of the internal components of animal B-ultrasound probes use piezoelectric crystals, which can cause natural aging of the crystals after long-term use. Improper use or external force such as dropping or hitting can damage the probe crystals. After crystal damage, the images detected by animal B-ultrasound detectors will show signal attenuation, black shadows, black bars, interference, defects, and other blind spots, which can cause doctors to be unable to diagnose, affect the quality of diagnosis, and even lead to misdiagnosis.

This type of malfunction is caused by a short circuit in the chip of the animal B-ultrasound probe. The short circuit of a chip can be determined by measuring the power supply voltage of the chip. If the power supply voltage of a certain chip or chip group is lower than others, it can be determined that there is a short circuit in that chip or chip group. Replace the corresponding chip or chipset to restore the probe's original characteristics and eliminate interference.
