2.0 Description
2.1 General
The D-Tec Vaporizer is designed to add Suprane™ (desflurane) inhalant anesthetic vapor to the medical gases supplied
to a patient. The vaporizer must only be mounted on a Dräger compatible anesthesia machine which is equipped with
an interlocking type manifold. The vaporizer must be supplied with dry medical gas and it must be connected to a
suitable electrical mains supply. However the D-Tec vaporizer cannot be used on the Narkomed Mobile anesthesia
system.
The D-Tec Vaporizer is designed to meet UL 2601-1, IEC 601-1 and IEC 601-2-13 recommendations.
When the vaporizer is connected to the electrical supply, the dial is turned to the q (Stand-by) symbol and the green
OPERATIONAL light located on the front display panel is illuminated, the vaporizer is in the electrical stand-by condition
and is ready for use, as described in Section 5.0 Operating Instructions.
w Warning: The performance of the anesthetic machine and vaporizer may be degraded if the machine
and vaporizer are mismatched.
w Warning: Do not install a D-Tec vaporizer in the right hand position of a Narkomed 6000 as this will
result in an incorrect fit and may cause leaks in the fresh gas delivery system.
w Warning: To avoid explosive hazards, flammable anesthetic agents such as Ether and Cyclopropane
must not be used in this vaporizer. Only anesthetic agents which comply with the requirements for non-
flammable anesthetic agents in the IEC 601-2-13 Standard, particular requirements for the safety of
anesthesia machines, are suitable for use in the presence of this vaporizer.
w Warning: As this vaporizer is not suitable for use with flammable anesthetic agents such as Ether or
Cyclopropane, the use of antistatic breathing tubes and face masks is not necessary. The use of
antistatic or electrically conductive breathing tubes when utilizing high frequency electric surgery
equipment may cause burns and is therefore not recommended in any application of this vaporizer.
w Warning: The functioning of this vaporizer may be adversely effected by the operation of equipment
such as high frequency surgical apparatus or short-wave therapy equipment in the vicinity.
w Warning: Do not operate the vaporizer other than with dry medical gases.
w Warning: The D-Tec Vaporizer must not be used in a Magnetic Resonance Imaging environment.
w Warning: The functioning of this D-Tec vaporizer may be adversely affected by electromagnetic
interference exceeding the levels specified in EN 60601-1-2.
w Warning: This product contains a small quantity of Mercury in the Tilt Switch mechanism and should be
disposed of according to local regulations.
w Caution: If the vaporizer is not likely to be used for a period of 12 months, the battery must be
removed. Failure to do so may result in damage to the vaporizer.
w Caution: 'No Output' alarm could be caused by downstream high frequency ventilation at greater than
60 breaths/min with an airway pressure of 100 cm H2O or pulsing the O2 flush faster than 1 pulse/sec
over a time period of greater than 10 secs.
w Caution: Refer to the User’s Manual for the Dräger Julian Anaesthesia Workstation for recommended
ventilator parameter limitations when using the D-Tec with a Julian.
The D-Tec Vaporizer uses a 100 to 120V a.c. 50/60 Hz electrical supply model. A label on the rear panel of
the vaporizer states the voltage requirement for each model.
The integral power supply unit consists of a transformer and an a.c. to d.c. converter which provides the

BATTERY
COVER
The equi-potential stud Y is located on the top of the vaporizer. It provides a means of connecting a
vaporizer to the anesthesia system to minimize any electrical potential difference between the vaporizer
casing and the anesthesia system.
2.2.6 Sump
The sump provides a means of containing the agent and includes the agent filling port, the drain, the
heaters and the agent level sensor.
The sump has a total nominal capacity of 390 milliliters (ml) which consists of a nominal 330 ml indicated
volume and a nominal 60 ml reserve.
Two 100W heater elements, located in the base of the sump, heat the agent to a nominal 39°C (102°F) to
generate the working pressure.
Two 100W heater elements located in the upper part of the vaporizer help to prevent condensation of the
anesthetic agent in the vaporizer.
The current supplied to power the heaters alternates between the two heaters in the sump and the two
heaters in the upper part of the vaporizer. This minimizes the current requirement.
The casing of the vaporizer is normally warm to the touch while it is connected to the electrical supply.
2.2.8 Monitors
Electro/mechanical monitors are incorporated to monitor the fresh gas/agent vapor pressure balance and
the agent volume.
The monitors control the operational status display and activate the appropriate alarm indication if a
monitored parameter malfunction is detected.
An agent level sensing probe is mounted in the sump to measure the agent level. When the sump contains
between 60 and 390 ml of agent, the LCD level display indicates the level of agent in the sump. If the agent
level decreases below 60 ml, the amber LOW AGENT light on the display panel flashes and the auditory
alarm is activated. If the agent level decreases below approximately 20 ml,
the red NO OUTPUT light flashes and the auditory alarm is activated. Vapor output then ceases.
If the vaporizer is tilted for 10-15 seconds while it is in operational mode and delivering vapor, vapor
delivery will be stopped, as indicated by the flashing No Output light and auditory alarm.

system has drained back into the bottle. Failure to do so may result in spilling agent.
8. Grip the bottle firmly and lower it from the upper stop position to the lower stop position.
9. When the bottle reaches the lower stop position, hold the bottle firmly in the filler port for a minimum
of 5 seconds to allow the small amount of agent in the filler system to drain back into the bottle.
10. To avoid dropping the bottle, support the bottle as it is automatically unlocked from the filler port and
released from the filler.
11. The valve on the bottle automatically closes to help avoid loss of agent.
6.1 Cleaning
w Warning: Do not put any substance other than Suprane™ (desflurane) into the vaporizer sump.
w Warning: Do not allow cleaning agents to accumulate in the filler, the gas inlet and outlet ports or
around the control dial.
For disinfection purposes, cleaning agents of a surface germicide type should be used. In terms of material
compatibility, cleaning agents which contain the following active ingredients are suitable for use:
• Aldehydes,
• Alcohol,
• Quartenary ammonium compounds.
w Warning: To avoid possible damage to the vaporizer, do not use the following compounds as cleaning
agents:
• Halogen hydrolysing compounds,
• Strong organic acids,
• Oxygen hydrolysing compounds.
To clean external surfaces, use a moist cloth and a neutral detergent (pH 7 to 10.5).
If the vaporizer is filled or partly filled with an incorrect volatile agent or other contaminant, proceed as
follows:
Return the vaporizer to an Authorized Service Center stating that the vaporizer is contaminated and if
possible, the type of contaminant in the vaporizer.
1. Turn the dial to q and disconnect the mains lead from the electrical supply.
2. Unscrew the battery cover securing screw and remove the battery cover from the base of the
vaporizer.
3. Remove the battery from the vaporizer and disconnect the terminals. Dispose of the battery.
w Caution: Only a Duracell 1604 or VARTA Energy 2000, 9 Volt battery must be installed in the vaporizer.
If any other battery is installed, it may damage the vaporizer.
w Warning: The battery terminals must be firmly clipped onto the battery to help prevent a possible
disconnection when the vaporizer is moved.
4. Clip the terminals firmly onto a new battery observing the correct polarity and insert the battery into
the vaporizer. Fit the battery cover to the base of the vaporizer and tighten the securing screw.

w Warning: Do not throw batteries onto a fire, do not open with force and do not recharge. To do so may
result in operator injury. When disposing of batteries, they must be treated as special waste and
disposed of according to local regulations.
2. The amber WARM-UP light is illuminated to indicate that the vaporizer is in its warm-up cycle and the
LCD agent level display bars indicate the amount of agent in the sump.
3. During the warm-up cycle, the shut-off valve (8) is closed to prevent the supply of vapor to the
pressure regulating valve (7), and the electronics (16) perform the zero check.
4. When the vaporizer attains the required operating temperature, the amber WARM-UP light is
extinguished and the green OPERATIONAL light illuminates to indicate that the vaporizer is ready for
use.
2. When the dial and rotary valve (1) are turned, a signal from the electronics (16) opens the shut-off
valve (8).
3. The pressure control transducer (3) sends a signal of the difference between the gas inlet pressure
and the regulated agent pressure to the electronics (16). The electronics alters the regulated agent
pressure by opening or closing the pressure regulating valve (7) to balance the pressures.
4. When the regulated agent pressure of the circuit is equal to the gas inlet pressure, the vaporizer
functions correctly.
5. The dial and rotary valve (1) indicated in Fig. 19, regulate the volume of vapor being delivered to the
fresh gas mixture.
6. The fresh gas mixes with the vapor just prior to the gas/agent outlet in the proportions consistent with
the selected dial setting.

Steady Back Pressure does not significantly affect the concentration of the agent delivered (v/v), but
does increase partial pressure of the agent. The increase is in the ratio of total back pressure to the
vaporizer calibration pressure of 760 mm Hg.
When either air or nitrous oxide is employed as the carrier gas, the output is lowered compared to the
output when oxygen is the carrier gas. This effect is the greatest (up to 20% of setting) at low flows
when nitrous oxide is employed, but using nitrous oxide reduces the required inspired concentrations
of volatile agent which can, depending upon the proportion, mitigate the decreases in output from the
vaporizer.
