Extract, gas flow diagram, gas inlet block
The compressed gases O2, N2O and AIR are fed in via the CS to the gas
supply block of the CS module.
The following description applies only to O2!
The additional O2 outlet (7), fitted with a self-closing coupling (8), permits
operation of an outpatient (Ambu) bag with oxygen metering (Oxydem) for
example. In the pressure reducer (40) the compressed gas is reduced to a
constant output pressure of 2.4 bar and routed to the digital gas mixer DAGMAR and to the O2 flush and the O2 emergency flow control valve. The
patient system can be flushed with O2 by way of the parallel-connected O2
flush valves (44) and (46) mounted on the left and right sides of the unit. The
flow is >35 L/min. By means of the “O2 safety flow” (42) flow adjuster the

The following description applies only to AIR!
Downstream of the non-return valve (15) is a tap for an optional secretion
suction device with ejector drive. Another tap supplies the DIVA supply module with propellant gas.

The description is based on the example of O2, and is identical for N2O and
AIR.
The compressed gas flows out of the CS from the CS port through the filter
(27) to the pressure sensor (28). The pressure sensor signal is processed in
the CS Block PCB (see also function description for CS Block PCB). The
compressed gas flows on to the non-return valve (29). The non-return valve
(29) prevents the gas from flowing into the open air from the connected cylinder via any CS port which may be open.
