Problem being addressed[edit]

Twelve percent of newborns need to receive immediate treatment for severe jaundice. This problem can be solved through the use of phototherapy treatment, but in low-income settings existing phototherapy options are often ineffective, costly, difficult to maintain, and improperly used.

Detailed description of the solution[edit]

Comet is a low-cost, high-performance, and compact jaundice treatment device intended to be used in rural clinics or as a backup for urban hospitals. This device is a cheaper, smaller and more energy-efficient device than Brilliance, another phototherapy device developed by the same design team. Comet utilizes high intensity light-emitting diodes (LEDs) which provide the intense blue light to treat jaundice. Comet has a lifespan of 3-5 years, requires minimal maintenance, and is designed to retail at less than $150.
