Jaundice mainly occurs in newborns, which is a common disease in the neonatal period. Data shows that about 50% of full-term infants and 80% of premature infants will have visible jaundice. The incidence is extremely high, but don’t think Its high incidence is ignored, and severe neonatal jaundice may lead to cerebral palsy or even death in infants.
The cause of jaundice is either excessive bilirubin or insufficient metabolism of the liver, and because the number of red blood cells in newborns is relatively high, the hemoglobin is on the high side, the life span of the partial blood red blood cells is short, and the destruction of red blood cells is more serious. , In the case of a substantial increase in bilirubin, coupled with the incomplete development of the neonatal liver, it is not surprising that neonates are prone to jaundice.
The reason for the traditional jaundice detector is naturally the bilirubin measurement technology, but it is mainly through blood drawing and other methods, and the results are obtained after the test. It is difficult for doctors, and it is easy to have doctor-patient disputes.
The percutaneous jaundice instrument measures through optical fiber technology, optoelectronic technology, electronic and information processing technology, etc., and uses the light wave difference between blue light wave (450mm) and green light wave (550nm) to determine the biliary red precipitated in the skin tissue of newborn babies. element concentration. It is mainly used to measure the transcutaneous bilirubin and determine the situation of neonatal jaundice.
Generally, there will be an original calibration sheet in the package, enter the calibration mode, align the calibration sheet to test, and the calibration is completed when the display is 0.
The transcutaneous jaundice meter can measure the transcutaneous bilirubin concentration instantaneously and the total serum bilirubin concentration by simply pressing the probe lightly on the forehead of the newborn.
