2. Infant warmer Infant Warmer , is a body  warming  device to provide heat to the body. This device helps to maintain the body temperature of the baby. Biomedical Engineering Department

3. Product description: Infant radiant warmers are overhead heating units. They typically consist of a heat source, a skin-temperature sensor, an automatic (servo) control unit, and visual and audible alarms. Biomedical Engineering Department

4. Working Principles: A heating element generates a significant amount of radiant energy in the far IR wavelength region (longer than three microns to avoid damaging the infant’s retina and cornea). The IR energy is readily absorbed by the infant’s skin; increased blood flow in the skin then transfers heat to the rest of the body by blood (heat exchange between the blood.

5. Function Include/major parts: Heater Skin temperature probes Examination light Phototherapy light(in some brand) Resuscitation Alarms Control panel X-ray cassette-Optional Baby Bed. Biomedical Engineering Department

6. Modes: Baby/SERVO MOD: Set temperature at e.g. 36.5 C, heater output will adjust automatically to keep baby at set temperature. If the baby temperature is below the set temperature, the heater output will increase; if the baby is at set temperature or higher the heater output will become zero.  MANNUAL MODE: The heat output from the quartz heating rod could also be increased or decreased manually. This is done by the heater output control knobs. This is called the manual mode of operation . Biomedical Engineering Department
