Instructions for use D-Vapor/D-Vapor 3000 31
Operating concept
Connection and Interlock systems for D-Vapor
Different connection systems are available for
operating the D-Vapor anesthetic vaporizer with
anesthesia workstations.
When anesthesia workstations have several
vaporizer connectors, the different Interlock
systems* ensure that only one vaporizer can be
used at any one time, and the others are switched
off and blocked.
The Interlock system on the vaporizer and
anesthesia workstation must be functional.
Plug-in adapter/plug-in connector
The plug-in adapter and the plug-in connector are
used to provide a secure connection and quick and
convenient changing of the vaporizer.
Most plug-in connectors have valves through which
fresh gas can flow even if the vaporizer is not
connected. These plug-in connectors can be
identified by the movable valve inserts in the inner
holes on the connector pins.
Some older vaporizers with plug-in adapters carry
an anesthetic agent code on the rear, which can be
read and displayed by anesthesia workstations
designed for this purpose (Dräger anesthesia
machines Cato and Cicero).
1 When connecting or disconnecting the
vaporizer, the control dial must be at the
T position (A) and the locking lever (B) must be
engaged in the control dial.
2 The holes in the plug-in adapter (C) on the
vaporizer fit onto the pins on the plug-in
connector (D) on the anesthesia workstation.
3 To secure or release, swing the locking lever (B)
into position and engage or disengage the pin in
the control dial cap of the vaporizer.
The locking lever (B) and pin help to ensure that the
vaporizer is handled correctly and that it can only
be fitted and disconnected when the control dial is
at the T position (A).
* The different Interlock systems cannot be combined. The
vaporizer can be converted from one system to another
by specialized service personnel.
WARNING
Risk of patient injury
More than one vaporizer can be switched on if
there is a malfunction in the Interlock system.
This may endanger the patient by causing
overdosing or a mixture of anesthetic agents.
The tabs in the two openings in the control
dial cap on the Interlock 2 must be undam-
aged. See also the chapter "Checking opera-
tional readiness" on page 54 for more infor-
mation.
