2 Technical Description
Driven by customer requests and requirements, the ARTEC model series had been
designed and developed as a compact universal version. At the same time high qualitystandards and maximum economy has been achieved.
The elementary structure ensures a good overview and quick allocation and adjustment of
parameters for the respective unit components. The ARTEC anesthesia unit is an
inhalation anesthesia unit that is equipped with a anesthesia agent specific vaporizer for
use in a semi-closed system
The unit consists of a basic housing of stainless steel in which a drawer is provided.
Located above that is the gas-mix unit (GME, with which the available medical gases O2,
N2O and (optional) compressed air can be dosaged.
The GME consists of an integrated pneumatic unit with relvant safety valves providing for
N20 block and O2 deficiency signal (in compliance with DIN 13252 and the dosage unit for
the above-mentioned medical gases.
On the right-hand side, an anesthesia agent specific vaporizer can be mounted on special
mounting racks ( one or two-fold).
Located on the basic unit and depending on model, there is provided a stainless steel shelf
for additional monitoring or a ventilation module with integrated monitoring (according to
DIN 13252).
On the reverse side of the unit there are standard connections for gas supply linea and
depending on model, holding racks for reserve bottles with integrated high-pressure
reducers.
The unit is also equipped with four plug sockets for electrical power supply for additional
monitors. These sockets are constantly supplied with current regardless of the Ventilators
ON/OFF power supply status.
2.1 Possible Expansion and Upgrading of the Unit
Basic Model
The ARTEC basic model is suitable for wall mounting. For such mounting, the mounting
rails of the basic unit ar attached to the V2A rails.
For wall mounting, exact vertical mounting of the unit must be strictly observed, otherwise
inexact mounting could lead to falsh measuring results of gas flows. An adjustable
distancer device provides a precise alignment of the unit.
Unit Model with Mobile Stand
The unit can be mounted on a mobile stand that enables and ensures variable site
operation.
The basic unit can be mounted on the mobile stand profile (80x30) by tightening the four
mounting bolts. The mobile stand can be equipped with a stand-alone oxygen,
compressed air and vacuum generator module „STAXEL“

Operating Instructions Artec
Gas Supply:
The unit is designed with a central gas supply coupling connection in compliance with DIN
13253. A set of hoses is supplied with the unit for the three types of gases O
, N2O and
2
compressed air ( if air is provided).
Gas supply can either be via a central gas supply network, or via bottle supply with 10 litre
bottles O2 and N2O. To ensure uninterrupted gas supply, in the event of breakdown of the
central gas supply, 2 litre reserve bottles can be connected.
An alternative to bottled gas supply, the ARTEC anesthesia unit offers the possiblity of a
decentalized oxygen supply via the supply „outlet“. This is the „STAXEL“ that has been
especially developed as an oxygen / compressed air and vacuum generator.
Ventilation Module:
The ventilation module ABVA is
easy to use and can eventually
mounted to the basic unit later on.
For this the V
A shelf is removed
2
from the basic unit. After that the
ventilation module can be mounted
to the basic unit via two mounting
bolts. The compressed air supply of
the ventilator is created via a
connection line to the basic unit.

3.1 Gasmixingunit 3 and 4
The gasmixingunit serves as a dosage unit for medical gases (e.g.
O2, N2O, Air). The choosen gases can mixed in a arbitary relation,
but the ratio-system guarantees a O2-concentration higher then 21
% (see below). The different gases are clearly displayed with
rotary buttons.
To avoid mistakes, the O
A unintentional move is prevented by a protection.
The dosing device makes a continuous flow enable, when opening
the valves by rotation against clockwise.
The O2-measuring range contains two measuring devices. This
makes a fine dosage possible.
The left measuring tube has a range from 0 to 2 l/min O2, the right
tube has a range from 2 to 15 l/min O2. As point of observation
serves the upper surface of the floating body.

3.2 O2 – Ratiosystem
The Gasmixingunits GME 3 and GME 4 can be equipped
optionally with a pneumatical system to assure at every flowrange
of N2O a minimum concentration of oxygen of 25 % O2 (+/- 5%).
The so called O2 - Ratiosystem avoids the delivery of pure N2O to
0
2
the breathing system.
Mode of operation
12

The O2 – Ratiosystem examines the O2 – Flowrate. If there is no
6
4
O2 – Flow the N2O – Line is blocked. Thus it is impossible to apply
2
pure N2O to the breathing system without opening the O2 – Valve
1
at the GME.
Only when the O2 – Valve is opened counterclockwise, a N2O –
flow according the flowrate of O2 can be adjusted. The minimal
2
achievable oxygen concentration is 25 % +/- 5%.

Control of function
1. Close O2 – and N2O – Valve at the GME.
2. Open N2O – Valve to maximum ⇒ There should be no N2O –
Flow
3. Open O2 – Valve counterclockwise ⇒ N2O – Flow is increasing
4. Adjust 1 l/min O2 ⇒ N2O – Flow should be 3 l/min +/- 0,2 l/min
5. Adjust 3 l/min O2 ⇒ N2O – Flow
should be 9 l/min +/- 0,6 l/min

3.3 O2-Flush
By pressing the O2 Flush push-button, a fast oxygen supply (approx.
50 litres per minute) is activated directly to the fresh-air outlet (not via
the anesthesia vaporizer).
After releasing the O2 Flush push button it must return to it original
position.
3.4 AIR/N2O Mode Switch
The Air / N2O Mode Switch is located below the rotary knobs for (AIR
/N2O). This offers a pre-selection of the gases AIR or N2O. The
respective dosage of the gases is effected via the regulation valve.
3.5 O2- supply deficiency signal
In the event of a pressure drop in the supply system (oxygen below
2.0 to 1.5 bar) an acoustic warning alarm is activated for a duration
of at least 7 seconds. An interruption is not possible).
3.6 Nitrous Oxide Block
In the event of a further fall in presure of oxygen to about 1 bar,the ratio of N2O is reduced
proportionately to the oxygen supply. Should there be a total fallout of oxygen, the N20 flow
is set to zero. Release of N2O is then closed.
The unit stand-by mode can be resumed only by setting the stipulated oxygen pressure of
at least 2 bar at the network inlet.
