2.1.3 Fresh air intake and O2 supply
2.1.3.1 Fresh air intake
Through a fresh air filter 84 02 926 at the back of the Incubator 30 L/min fresh air are taken in
by dosing via the running impeller.
2.1.3.2 O2 supply
Incubator 8000 IC:
There are two possibilities for 02 supply in Incubator 8000 IC:
a. External 02-supply
b. Oxygen control
Incubator 8000 SC / NC:
With Incubator 8000 SC / NC only external 02-supply (a.) is possible.
a. external O2 supply
Via a socket oxygen can be supplied to the Incubator through a flowmeter. According to
specification the oxygen concentration has to be monitored with an additional oxygen
measuring instrument with upper and lower alarm limit.
b. oxygen control
An automatic control can be carried out with the integrated 02 concentration control. According
to set value deviation one valve with 29 L/min is opened by the electronic control. According to
specification the oxygen is supplied via the fresh air filter to the patient room.
2.1.4 Heating unit
The following function blocks are on the unit:
- fan motor
- air heating with over-temperature fusing
- humidifier with over-temperature fusing
- mains transformer
- auxiliary mains transformer for mains connection
- semiconductor relay for air heating and humidifier
- safety relay for heatings and 02 valves
- Sensor for monitoring of:
the air heating (I/U converter)
the vaporizer (temperature for water shortage alarm)
the impeller (fan)
- fuses for the mains input and the internal
supply voltages
