Design and Operating Principles
Design and Operating Principles
The phototherapy lamp consists of a plastic-coated aluminium
housing with electronic switching units, fluorescent lamps for
light therapy and lighting, control circuits, fuses and an "hours
used" meter.
The lamp may also be mounted on a mobile stand (order
separately) which allows it to be used at an angled position
when used with infra-red heated warming cots, such as the
Dräger Babytherm 8000.
The light is helpful for malfunctions of bilirubin metabolism. If a
newborn baby develops icterus because detoxification of the
liver has been inadequate, therapy to lower bilirubin
concentration may be required as early as the first day.
Phototherapy has been found to be a reliable treatment for
excessive bilirubin concentration.
The light converts the bilirubin into a water-soluble form by a
photochemical reaction and so enables natural excretion via
bile and urine.
The blue portion of the light spectrum is most effective in
decomposing bilirubin at an absorption peak of 460 nm. The
Dräger fluorescent lamps emit light in this peak.
