Semiconductor Light Emitting Devices for Phototherapy of Jaundiced Newborns or Circadian Rhythm Disorders


Stanford Reference:

96-113


Abstract


Stanford researchers have taken advantage of lightweight, energy efficient LEDs (light emitting diodes) to develop two novel phototherapy technologies. One invention is a garment (clothing, wrap or blanket) that can be used to treat neonatal jaundice, a condition that affects as many as 400,000 newborns in the United States every year. The potential device can be made lightweight and portable so that it can be worn at home, in the hospital, or while in transit. Because LEDs have a specific spectral range and do not produce as much heat as traditional light sources, the garment can provide high light intensity over a larger surface area of the newborn than is possible with conventional phototherapy beds. The technology could also used to treat patients with Crigler-Najjar syndrome who require ongoing treatment for jaundice.

The second invention utilizes LEDs for treating circadian rhythm disorders such as jet lag or seasonal affective disorder (SAD) with light delivered to the retina and/or vascular tissue. For delivery to the retina, the inexpensive, compact device is integrated into the frames of eyeglasses and positioned to direct light into the eyes of the subject. For delivering light to vascular tissue, the LEDs are encased and secured against the skin of the subject. In both cases, the intensity, timing, and wavelengths of the lights can be adjusted and fine-tuned.

Stage of Research:
Prototypes of both the neonatal jaundice garment and the circadian rhythm/seasonal affective disorder devices have been made.

Applications


  • Treatment of neonatal jaundice (including Crigler-Najjar syndrome)
  • Treatment of circadian rhythm disorders, such as:
    • jet lag
    • seasonal affective disorder
    • disorders resulting from “graveyard” shift work

Advantages


  • General Advantages of LED Technology
    • light-weight and portable
    • energy efficient - low power consumption, low production of undesired heat, precise control of light wavelength range
    • structurally robust
  • Advantages for Jaundice Treatment
    • rapid reduction of serum bilirubin levels
    • can be used in home, at hospital, or in transit
    • high light intensity over a larger surface area than conventional phototherapy beds
    • no eye shield needed because garment prevents light from reaching baby's eyes
    • prevents discomfort and hypothermia because garment fully covers baby
  • Advantages for Circadian Rhythm Disorder Treatment
    • portable - treatment can be given at any time
    • inconspicuous
    • does not interfere with vision
