Airflow Routing; Air Temperature Control - Dräger caleo Instructions For Use Manual

Airflow Routing

The heated and humidified air flows into the canopy from
both sides. It is guided up the inside of the front flap, along
the canopy cover and then down the two transverse sides by
suction. The air from the interior is mixed with fresh ambient air
by an air filter and is circulated by a fan impeller. Along this
path, the air is channelled past an electrically powered heater
and is humidified if necessary
The patient lies in a calm zone with low airflow speeds.
Heat loss due to flow is kept to a minimum. When opening the
large flaps or access ports (Caleo
hot air curtain remains to prevent cooling in the patient
compartment.

Air temperature control

The user sets the desired air temperature in the patient capsule
by means of the control panel (set value for air temperature in
air temperature mode).
The current air temperature is measured by the air temperature
sensor in the patient capsule (at the patient's head end of the
incubator) and is then compared to the set value. If the set
value is greater than the actual measured air temperature, the
heater receives the signal to apply more heat. The air tempera-
®
ture inside Caleo therefore increases.
If the set value is lower than the actual measured air tempera-
ture, the heater receives the signal to apply less heat. The air
