B ultrasound probe often appear what faults, B ultrasound probe will appear common failure analysis

In medical imaging equipment, ultrasound used in many places, ultrasound is more applicable to the liver, gallbladder, kidney, bladder, uterus, ovaries and other organs of the diagnosis of disease. ultrasound is also cheaper, and there is no adverse reaction, can be repeated checks. What are the malfunctions of ultrasound probes? The following is the ultrasound probe will appear the common failure analysis, quickly look at it!

Common Failures Failure 1: crystal damage

Phenomenon: the detected image is interspersed with black shadows, and black bars of interference.

Analysis and repair: most of the B ultrasound probe internal piezoelectric crystals, long-term use of the crystal will cause natural aging, non-standardized use or wrestling, touching and other external forces will cause damage to the probe crystal damage, crystal damage, ultrasound detector detected by the image will appear signal attenuation, the image of the image of the black shadow, black bars, interference, defects and other blind spots, the image of the seriousness of the image is blind, which will cause doctors can not diagnose, affecting the quality of diagnosis, and the image of the doctor. These will cause the doctor to be unable to diagnose, affecting the quality of diagnosis.

Common Failure Failure 2: cable damage

B ultrasound probe cable is a very high quality requirements of the multi-core highly shielded cable, workmanship is very fine, the cable within the wire tight, more than hundreds of roots, like hair thick. Due to the probe multi-directional use, the cable bending, twisting makes the cable's outer protection zone insulation layer will break the skin, fracture, revealing the signal line inside, the shielding layer of the destruction, disconnection, the image will produce interference with the ripples and defects.

Phenomenon: the monitor image serious interference, full screen appeared snowflake-like light spots, flicker feeling strong, and can not adjust the glow.

Common Failures Failure 3: Lens Failure

Phenomenon: Aloka ssd-620 black and white ultra, the monitor image appears in the vertical dark bars. Squeeze the probe vertical dark stripes, vertical dark stripes obviously weakened, replace the same type of probe vertical dark stripes disappeared, the preliminary judgment, the acoustic lens layer and the matching layer between the possible degumming.

Analysis and overhaul: acoustic lens is the upper part of the ultrasound probe in contact with the human body gel-like professional substances, long-term use will cause natural wear and tear of the acoustic lens, scratches, cracking, corrosion, degumming, blistering and other damage, especially due to the coupling agent into the lower layer of the corrosion caused by not only artifacts such as the blind spot, resulting in misdiagnosis of the doctor, the severity of the damage to the ultrasound probe crystals or caused by the leakage of electricity, endangering the body of patients, bringing harm to the patient and the machine. that brings harm to both the patient and the machine.
