3. TECHNICAL DESCRIPTION
3.1AM5000 AM5000/3 AM5000/5 anaesthesia module
AM5000 - AM5000/3 – AM5000/5 regulate the upply and concentration of the ga mixture (Air, O2, N2O),
and al o upplie it to the anae thetic ga vaporizer.
It al o allow the election of the ga mixture to be upplied (Air-O2, or N2O-O2) and the enrichment (with
oxygen) of the upplied ga mixture for emergencie . The AM5000 - AM5000/3 – AM5000/5 i al o equipped
with the MIX-LIFE device that guarantee a minimum of 25% oxygen in all open-tap condition .
By u ing the three gauge located on the front panel, the medical ga e upply pre ure coming from the
central ga in tallation can be continuou ly controlled (preci ion ± 10%).
The flowmeter permit the mea urement of the flow the of the corre ponding ga e with a preci ion of ±
10% of the di played value or ± 1% of the bottom of the cale, by choo ing the highe t of the two value .

REMEMBER: DO NOT CONSIDER THE AIR LINE FOR ANAESTHESIA MODULE A 2 FLOWETERS.
Below i the pneumatic diagram which de cribe the unit:
The main purpo e of the pneumatic di tributor i to:
1. take the medical ga e form the pipeline connection or cylinder connection .
2. monitor the operating pre ure (pre ure gauge )
3. elect the type of mix that hould be admini tered to the patient (ga elector AIR-N20)
4. take the elected ga e to the flowmeter box
5. allow the mixed ga e to be taken to the patient ventilation y tem (breathing y tem)
6. enrich the oxygen mixture in ca e of need (O2 bypa )
All the upply inlet are protected by a non-return valve, in order to avoid a leak of ga in ca e there i no

The gauge have a colored band indicating the range at which there i the correct upply pre ure.
The ga e upplied to the AM5000 - AM5000/3-AM5000/5 are connected to the flowmeter box in order to
regulate the flow and to mix the ga e that are then ent to the anae thetic ga vaporizer . From the e they

1c) insert washer 8 onto the axis of pin 6 (mix life system) and block with loctite 270 the flange 9 onto
axis of pin 6 keeping a distance of 2mm0.5mm (wait at least 30 minutes before putting pressure onto
washer 9)
1d) insert and lubricate with vaseline the o ring 13 (OR 2018) onto the body of pin 2.
1e) lubricate with vaseline the edge and threading of pin 2.
1f) screw completely pin 2 on body 4 and pin 6 on body 7. Repeat about 5 times this procedure,

10 of the pin.
1h) repeat the procedures of points 1f and 1g until a good matching of the screws and mother screws
are obtained and that the spacing between edge of pin and regulator body is created.
WARNING !!!: the procedures 1f and 1g are very important in order to have a good closure of the flow
regulator, and if they are not done properly, it will be necessary to disassemble the flow regulators
later.
!
•The metal components have to be properly washed and dried before

The flowmeters should be handled with care, and should be wrapped in the paper in which
they were shipped , not with nylon.
Do not rube them with your hands, fabric or paper.
3f) All the tarring and flowmeter check hould be done with compre ed air at 3.5 bar.
3g) With the flow regulator clo ed, regulate the pre ure of the oxygen (21) at 2 bar and that of the nitrou
oxide (22) at 1.4 bar. In ert and remove the compre ed air upply 3 time o that the reducer are
tabilized, if nece ary correct the regulation.
3h) The leak te t hould be checked in two point :
1) - down from the valve (2, 6) in order to check the proper that there are not leak in the clo ure of
the valve .
2) - up from the valve (2, 6) in order to check the proper that there are not leak in the pneumatic
circuit.
1) Verify that the leak of each valve connecting the flowmeter corre ponding to a low flow gauger. The
mea ured leak hould not be higher than 20 ml/min. for the O2, N2O, Air.
The lack of ignificant leak hould be guaranteed without forcing the regulator.
If there i a ignificant leak it can be due to two factor
-a manufacturing defect that affect the hold of the pin (thi i the mo t probable cau e).
In thi ca e it i nece ary to repeat the preparation for operation of the regulator. If after two trie the
hold of the group BODY- PIN (2-4 or 6-7) it hould be replaced
- manufacturing defect that affect the hold of one of the o-ring (check that their urface i not damaged
during the a embly due to a re idual depo it)
2) Alway with the clo ed flow regulator clo e the air upply up from the control gauge (M) and verify
that the pre ure doe not go lower than 0.5 bar in 1 minute for all the 3 ga line at the ame time.
If the decrea e in pre ure i higher, there i a leak in the pneumatic circuit.
Verify the proper connection of the tube and connector, and if the leak continue u e the leak te ter
with bubble in the point of connection of the connector and on the pre ure reducer .
4) Check for flowmeter capacity
!
4a) In order to check the capacity 1.00, 4.00 l/min of the O2 connect the O2 flowmeter 23 with a tube at the
tart of a low flow gauger
Regulate the O2 flowmeter in order to take the bubble indicator to 1.00, 4.00 l/min of the cale of the
flowmeter.
In order to verify the capacity 8.00, 12.00 l/min of O2 connect the O2 flowmeter with a tube at the tart
of a high flow gauger.
Regulate the knob of the O2 flowmeter in order to place the bubble indicator corre ponding to the value
8.00, 12.00 l/min of the cale of the flowmeter.
The flowmeter deliver a correct do age if the value read on the flow gauger, a per the following table:

It i rare that the tolerance are within the limit on the fir t try, however by the trend of the value you
will receive the information nece ary for doing the correction .
The following cenario are po ible:
- O2 percentage tend to be higher than 25%
- O2 percentage tend to be lower than 25%
Thi problem i due mainly to the pre ure and econdly to the pha e between the gear .
If the O2 percentage tend to be higher than 25%, the pre ure of the N2O need to be increa ed.
If in tead the O2 percentage tend to be lower than 25%, the pre ure of the N2O need to be
decrea ed.
Each time the regulator i readju ted it i nece ary to connect and di connect 3 time the compre ed
air upply, o a to tabilized, if nece ary adju t the regulation.
5d) Repeat the operation from point 5 until the value are not within the tolerance indicated on point 5C.
5e) Due to mechanical play that can occur in thread and gear , the value that are read in opening and
clo ing will be lightly different. On the tarring form, the operator hould write down both of the e value ,
that hould be within the tolerance in the wor t condition.. The difference between the value in opening
and clo ing will be more ignificant on low flow .
In time, due to the u age of the machine, the O2 percentage will tend to increa e, in tead of decrea ing.
Thi i important a far a the afety.
5f) The tarring will again be checked, once the a embly of the flowmeter box in completed.
6) Assembly of flowmeter box
6a) Remove the flowmeter and upply tube from the regulator block
6b) In ert 1 ga ket and 1 OR 2050 in each upper lodging of the flowmeter from the upper block of the
flowmeter box.
6c) Screw the afety valve on the upper block of the flowmeter box.
6d) A emble the pre ure reducer AR 1000 onto the reducer upport, keeping the N20 reducer to the left,
and the O2 to the right (place the reducer upport with the hole facing the front)
6e) A emble the right and left panel on the regulator block with crew TSEI M3x6, (verify before
a embling the panel that the head of the flat crew i completely hidden in it lodging, otherwi e
adju t the lodging.
6f) Place the flowmeter on their lodging .
6g) Place the internal panel o that the flowmeter are vi ible when looking the flowmeter box from the
front.
6h) Set the reducer upport on the upper part of the right and left panel , o that it cover the body of the
pre ure reducer can be een from the back, with 2 flat crew elf-threading M3x10 .
6i) A emble the upper block of the flowmeter box with crew TSEI M3x6.
