Problems solved by technology

This means that the baby may be disposed of longer than necessary and therefore have more side effects than necessary
Also, due to the workload, it is usually not possible for a neonatologist to spend more than every twelve hours checking TSB levels

Abstract

A sensor system, for use in a phototherapy system for treatment of neonatal jaundice, designed to harvest energy from the phototherapy system. The sensor system is wirelessly connected to the phototherapy system and provides measurements of the total serum bilirubin levels of the infant. The continuous measurement of the total serum bilirubin allows the phototherapy system to personalize the treatment of each infant, minimizing any unwanted side effects of the phototherapy. The energy harvesting performed by the sensor removes the need to manually replace or recharge batteries, which may disturb the infant during treatment, and may enable the sensor system to operate without an energy storage device, such as a battery, altogether.

Description

technical field [0001] The present invention relates to the field of phototherapy, and more particularly to neonatal phototherapy, for example to treat hyperbilirubinemia. Background technique [0002] Neonatal jaundice is a condition that affects more than half of newborns during their first week of life. In newborns, jaundice may develop due to two factors: the breakdown of fetal hemoglobin, as it is replaced by adult hemoglobin, and relatively immature hepatic metabolic pathways in the liver, which cannot bind bilirubin and therefore Bilirubin is not excreted as quickly as in adults. These can lead to a buildup of bilirubin in the blood, known as hyperbilirubinemia, which can cause visible yellowing of the skin. [0003] High levels of bilirubin put infants at risk for kernicterus, the deposition of toxic levels of bilirubin in the brain that can cause permanent nerve damage. It may take a few days for the baby's system to begin eliminating bilirubin from the blood at ...
