Day/Night Configurable Phototherapy Device
ABOUT
Neonatal hyperbilirubinemia is defined as elevated levels of bilirubin in the blood and is a liver condition that affects over 60% of newborns, especially those delivered preterm. In highly developed countries access to phototherapy devices reduces the risk of severe hyperbilirubinemia, however, low cost alternatives are necessary to address the need in less economically developed areas.
the problem
Many low resource hospitals don’t have a stable source of electricity and use phototherapy devices that have bulbs that only last 2–4 weeks. Therefore, there is a need to develop low-cost devices that have easily replaceable light sources and do not require continuous external electricity.
OUR SOLUTION
The phototherapy device offers a solution to use indoors using electricity powering an LED array and outdoors using the sun as the light source. The top of the enclosure is removable to enable maintenance of the device. There is a mosquito net that surrounds the device to ensure protection from insects and maintain enough airflow.
