Gerium Medical's BiliCare Noninvasive Bilirubin Meter for neonatal jaundice screening is using a Macro Sensors Miniature LVDT Linear Position Sensor as a component of the sophisticated measuring technique that ensures accurate calculation of transcutaneous bilirubin levels in a newborn without puncturing the skin, thus reducing the risk for infection.
Traditionally, newborns are screened for high bilirubin levels to assess the risk of neonatal hyperbilirubinemia by taking blood samples through heel sticks. The new BiliCare™ system reduces the number of heel punctures by accurately measuring the level of transcutaneous bilirubin in a noninvasive manner.
Based on spectroscopy, the patented BiliCare technology measures the level of transcutaneous bilirubin in newborns born at the gestational age of 24 weeks and above, and of all races without regards to skin color, by transmitting light at different wavelengths through the outer ear. The amount of light absorbed by the bilirubin is calculated by comparing the intensity of the light before it enters the tissue with its intensity after it leaves. The transcutaneous bilirubin of the newborn is, then, calculated according to a customized algorithm.
CD Series Miniature AC LVDT Linear Position Sensors measure the thickness of the neonates tissue through which the transmitted light passes. With a compact 3/8” diameter design, these lightweight AC-operated LVDTs are suitable as integral parts of medical devices with tight space restrictions and high accuracy requirements. The LVDT sensor has shown to achieve an accuracy of ±30 microns in tissue thickness measurement.
