System basics
1.1 Intended use
The BT-550 Infant Warmer is intended to emit controlled, evenly distributed overhead heat to the body
of premature infant and other newborns that cannot effectively regulate their body temperature. This
device can be used before any treatment or operation of an infant. The device has two operating
functions; the baby mode and the manual mode. In the baby mode, the temperature is controlled by
the infant
’
s skin temperature. The infant
’
s skin temperature is compared to the temperature setting. If
the measured skin temperature is lower than a temperature setting value, the warmer operates to
increase the skin temperature of an infant. In the manual mode, the warmer operates for a predefined
time.
The device has the option for weighing scale and SpO2 measuring functions. Weight and SpO2 of infant
can be measured using the options. In the SpO2 measurement, the sensor is place at the end of a
finger. By measuring the intensity of reflected light, depending on the concentration of dissolved
oxygen in the blood determines the oxygen concentration.
