Abstract
The Airlangga Bilirubin Nesting (AirBiliNest) is a novel portable phototherapy device developed to address the challenges of treating neonatal hyperbilirubinemia in resource-limited and home-based care settings. By integrating blue monochromatic LEDs into a sleeping bag model, it enables safe light delivery while allowing parental bonding and uninterrupted breastfeeding. This study aimed to evaluate the device’s thermal regulation, irradiance output, and irradiance decay over time, as well as to assess acceptance and usability among healthcare providers. A simulation study was conducted in the Neonatology Unit of Airlangga Teaching Hospital using a neonatal mannequin over a 48- hour period, with standardized measurements of surface temperature, light irradiance, and decay rates taken every 12 hours at varying intensity levels. Temperature monitoring demonstrated that the device maintained safe thermal limits at 10–20 μW/cm²/nm, while overheating was noted at 30 μW/cm²/nm after 24 hours. The device delivered adequate irradiance levels for standard and intensive phototherapy (ranging from 11.29 to 34.65 μW/cm²/nm), with decay rates between 0.012 and 0.057 μW/cm²/nm per hour. A questionnaire administered to 32 healthcare professionals revealed favourable responses regarding the device’s perceived usefulness, ease of use, and potential for clinical adoption. In conclusion, the AirBiliNest meets essential safety and performance standards for phototherapy, while also showing promising acceptance among healthcare providers. Further clinical studies are recommended to assess its effectiveness in real patient settings.
