3.7 Vaporizers
CAUTION
Read the instruction manual supplied with the
vaporizer before clinical use.
3.7.1 Vaporizer Mounting Systems
Vaporizers for the administration of volatile
anaesthetic agents can be fitted as follows:
(a) Penlon Delta Selectatec compatible
vaporizers, mounted on a Selectatec
compatible universal backbar.
(b) Penlon Delta Cagemount vaporizers
mounted on a Modura rail (check that
relevant national standards for your
country allow fitment of more than one
cagemount type vaporizer).
WARNING
Vaporizers must always be securely mounted,
and never used free-standing.
Unmounted vaporizers may be accidentally
tipped resulting in uncalibrated and excessive
volumes of liquid anaesthetic drug entering
the breathing system.
Vaporizers of any description must not be
installed or connected between the Common
Gas Outlet (CGO) and the Breathing
System, unless they are specifically
designed for such use. (If this is done, the
oxygen flush flow will pass through the
vaporizer, and severe overdosage may
result).
3.7.2 Selectatec Compatible Vaporizer
Selectatec compatible vaporizers, (e.g. the
Sigma Delta with the Selectatec connector
block), may be mounted on a universal back
bar manifold, built onto the Prima SP range
as an option.
Single and two-station manifolds are
available, with each station fitted with two
valve capsule assemblies for vaporizer
connector block attachment.
When a vaporizer is installed on a station the
valves on that station open automatically to
allow gas flow into and out of the vaporizer.
Removal of the vaporizer from the station
closes the valves on that station.
Selectatec compatible vaporizer interlock
systems are described in the literature
supplied with the vaporizer.
3.7.3 Cagemount Vaporizer
Vaporizers fitted with cagemount tapers
have the male taper (inlet port) on the left,
and the female taper on the right (viewing
the front of the vaporizer).
It is recommended that detachable
cagemount connectors are retained with a
safety clip (catalogue number 52275) to
prevent inadvertent disconnection.
3.8 Common Gas Outlet (CGO)
The outlet (1) can be located at the front or
rear of the machine, and has a 22 mm male
taper and concentric 15 mm female taper.
The male taper incorporates the Penlon
Safelock system designed to prevent
accidental disconnection of the breathing
system.
Oxygen Flush
An emergency oxygen flush valve button (2)
is mounted at the font of the machine and is
marked ‘O
2 FLUSH’.
Depressing the button provides a delivery of
between 35-75 litres/min of oxygen through
the common gas outlet (1).
Releasing the button allows the spring-
loaded valve to return to its normal position.
