Description

C A U TIO N
Read the instruction manual supplied with the vaporizer
before clinical use.
3.7.1 Vaporizer
Mounting S ys t e m
Use Penlon Sigma Delta MRI Selectatec-compatible
vaporizers (1) with interlock, mounted on the Selectatec
compatible universal backbar, for the administration of
volatile anaesthetic agents.
W A RN I N G
1. Prima 451 anaesthetic machines must only be u s e d
with Sigma Delta MRI vaporizers installed on t h e
Selectatec-type backbar sys t e m .
2. Vaporizers must
always be s e c u r e l y mounted,
and never used
f r ee- s t a nd i ng . Unmounted
vaporizers
may be a cc i d e n t a ll y tipped resulting
in uncalibrated a nd excessive volumes of liquid
a
n ae s t h e t i c drug entering the breathing system.
Do not install or connect any vaporizer of any description
between the common gas outlet (CGO) and the breathing
system, unless it is 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 Sigma Delta, Selectatec-
Compatible V a po r i ze r
A two-station manifold is fitted, 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.
3.7.3 Sigma Delta Vaporizer
Interlock S ys t e m
Sigma Delta Selectatec-compatible vaporizer interlock
systems are described in the literature supplied with the
vaporizer. See also, section 5.3.4 in this manual.
3.7.4 Refilling a key-filler type Sigma Delta MRI vaporizer
in the MRI facility
WARNING
1. Do not bring any bottle or container of anaesthetic
agent into the MR facility unless it is specifically
labelled to be used in an MRI scanning room.
2. For Key-fill vaporizers (see section 5.1 in the Delta
vaporizer user manual) check that the key filler
adaptor (2) is labelled MR Conditional.
3. Do not use an unlabelled, early-type key filler adaptor
that may have been brought to the MRI facility from
your hospital’s operating theatre.
If in doubt, refill the vaporizer in a suitable location
outside the MRI facility.
4. It is the user’s responsibility to ensure that any
third-party objects required for the filling process are
suitable for use in the MRI facility.
Always
follow the procedures in the vaporizer user manual .
