Section 2
General Description
Auxiliary Oxygen
Flowmeter
(Optional)
For the delivery of a metered flow of pure oxygen (for example, delivery
of oxygen through a nasal cannula), an optional auxiliary oxygen
flowmeter can be mounted on the left side of the flowmeter bank. This
flowmeter can be used when the machine is turned off. A zero stop
prevents damage to the flow control valve seat.
Vaporizers
The Narkomed 2B can be equipped with up to three Vapor 19.1
vaporizers for administering liquid anesthetics.
Exclusion System
A cam and lever interlock system, incorporated into the vaporizer bank,
prevents more than one vaporizer from being activated at a time. The
interlock system requires all unused vaporizers to be locked in their zero
volume percent positions.
WARNING: Only one vaporizer can be activated at a time. If the
exclusion system permits simultaneous activation of more
than one vaporizer, do not use the anesthesia machine.
Contact a North American Dräger qualified technical
service representative for adjustment.
Filling Systems
Two filling systems are available for the Vapor 19.1 vaporizer: the open
funnel system and the key-indexed safety system.
