AI Technical Summary

Technical Problem

Conventional phototherapy treatments for neonatal jaundice, such as incubators and phototherapy blankets, fail to provide comprehensive skin coverage, especially in occluded areas like joint folds and underarm regions, leading to discomfort, reduced efficacy, and the need for eye protection, which impede bonding and breastfeeding.

Method used

A phototherapy garment with integrated LEDs that emit blue light, conforming to the body to ensure even light delivery to occluded areas, using a stretchable textile substrate and serpentine circuit configuration, ensuring softness and breathability, and incorporating transparent encapsulation for electrical components.

Benefits of technology

The garment provides effective phototherapy by maximizing skin surface coverage, ensuring comfort and safety, while maintaining therapeutic irradiance levels, allowing for uninterrupted bonding and breastfeeding.

Abstract

A phototherapy garment for treating jaundice includes a base garment configured to conform to a patient's body and includes a stretchable textile substrate, a plurality of conductive traces integrated into the base garment, and a plurality of light-emitting diodes (LEDs) oriented to direct light toward a wearer's skin. Methods of treating jaundice using the phototherapy garment and methods of manufacturing the phototherapy garment further define characteristics of the phototherapy garment.
