New breakthroughs in research: jaundice newborns can receive led phototherapy at home

Jan 16, 2018

Because of liver or spleen problems, patients with jaundice can not normally metabolize the bilirubin in the blood, resulting in yellowing of the eyeball and skin. Current jaundice newborn mainstream treatment is "phototherapy box", using the lamp in the box to break down the bilirubin, but the inside of the baby during the treatment can not contact with the parents, and need to use protective glasses to protect the eyes.

The wearable device named "jaundice suit" is a baby with hundreds of LED lights, which can cover the baby's arm, legs and torso, and the body can be networked and collect physiological data of the human body, and the internal LED lamp can also be controlled remotely. Research and Development student Joshua Harper said the device made up for the inadequacy of past equipment.

Jaundice suit built-in LED lights can decompose the body of the baby's bilirubin, to prevent children's eyes from the damage of phototherapy, in medical research, doctors can remotely measure heart rate and activity status, can record patients outside the hospital data, parents are more likely to participate in care. But its disadvantage is that it only covers the torso and limbs, requiring longer treatment time.

Effect of LED phototherapy in jaundice


The Swiss Federal Institute for Materials Testing and development (EMPA) has similar research results at the beginning of November last year, which developed wearable led phototherapy pajamas for newborns with jaundice, and made use of a special weaving method to combine the optical fiber with the textile technology and set the LED as the light source of the optical fiber guide and the weaving angle Keep the light wavelength at around 470nm and shine on the skin.

Neonatal jaundice is one of the common symptoms of infants, all countries have input related research, and with the progress of LED technology, LED light therapy also appeared. According to a 2015 study by the affiliated Hospital of Aalborg University in Denmark (Aalborg University Shetty), the wavelength 459nm blue LED light and wavelength 497nm green color led all have therapeutic effects on jaundice.
