dideco D 902 LILLIPUT 2 Mode D'emploi page 5

Open the "ON-OFF" manifold (position "ON").
Version OXYGENATING MODULE only (fig. 3)
ARTERIAL LINE: remove the red cap on the oxygenator arterial
outlet (ref. I) in order to connect a 1/4"-5/16" line.
PUMP LINE: the pump segment should be set up between the
venous reservoir outlet connector and the oxygenator venous
inlet connector (ref. F) taking account of the direction of rotation
of the pump.
OXYGENATING MODULE PURGE LINE: remove the protective cap
and connect the male luer end (ref. B) to a female luer filtered inlet
on the cardiotomy.
OXYGENATING MODULE RECIRCULATION LINE: remove the pro-
tective cap and connect the male luer end (ref. A) to a female luer
placed on the venous return line.
CAUTION
If at the end of the bypass blood recovery is envisaged, set up
an "ON-OFF" manifold (with female and male luer lock con-
nections) between the male luer lock of the oxygenating modu-
le recirculation line and the venous reservoir used. Open the
"ON-OFF" manifold (position "ON").
ARTERIAL SAMPLING LINE: remove the protective cap from the
luer connection placed near the arterial outlet (ref. L). Attach to it
the male luer of an arterial sampling line.
WARNING
Male luers not supplied with SORIN GROUP ITALIA products
may damage the one-way valve placed inside the oxygenator
arterial sampling luer. When connecting, make a visual check
that the male luer does not reach as far as the one-way valve.
7) SAMPLING MANIFOLD
Versions with SOFT (fig. 1) and RIGID (fig. 2) VENOUS RESER-
VOIR
It is possible to remove the LILLIPUT manifold from its position
and mount it on the appropriate holder (D 712).
The tube coil attached to the manifold allows it to be repositioned
to a range of approximately 1 metre. Check that the selector swit-
ch (ref. 9) is in the "OFF" position.
8) CONNECTING THE TEMPERATURE PROBES (fig. 1, 2 and 3)
The connection for the arterial temperature probe (red - ref. 14
and H) is positioned next to the arterial outlet, whilst the venous
probe site (blue - ref. 13 and G) is at the side of the venous inlet.
SORIN GROUP ITALIA temperature probes have code 9026.
9) RECIRCULATION AND PURGE LINES
Versions with SOFT VENOUS RESERVOIR (fig. 1)
Check that the white clamp positioned on the recirculation line
between the LILLIPUT arterial outlet and the venous reservoir is
open.
Version with RIGID VENOUS RESERVOIR (fig. 2)
Check that the clamp positioned on the recirculation line between
the LILLIPUT arterial outlet and the rigid venous reservoir is open.
All versions
Close the blue clamp on the oxygenator purge line.
10) CONNECTING THE GAS LINE
Connect the 1/4" gas line to the connector on the upper cover
labelled "GAS INLET". Ensure that the gas supply is from a suita-
ble air/oxygen mixer such as the Bird, code 9374 (available from
SORIN GROUP ITALIA) or a system with compatible technical fea-
tures. A capnograph connector can be found in the centre of the
connector marked "GAS ESCAPE".
CAUTION
- The "GAS ESCAPE" system is designed to avoid any possible
risk of blocking the gas outlet; such blockage could cause the
immediate passage of air to the blood compartment.
- SORIN GROUP ITALIA recommends the use of a bubble trap or
filter on the arterial line to reduce the risk of emboli
transmission to the patient. Such risk could be due to:
1) collapse of the soft venous reservoir, caused by a reduced
venous return; arterial pump cavitation generates emboli;
LILLIPUT purge not being correctly operating, allowing air
to enter artery via the pump.
2) the air which is delivered via the venous cannulae is not
removed promptly from the venous reservoir and is
aspirated by the arterial pump.
- If there is to be continuous administration of anticoagulant
to the patient:
Versions with SOFT VENOUS RESERVOIR
Use a female luer lock connector on the soft reservoir venous
return connector.
Version with RIGID VENOUS RESERVOIR
Use one of the two filtered female luers lock positioned on the
rotating head of the rigid reservoir.
11) VAPOROUS ANAESTHESTICS
The oxygenator is suitable for use with volatile anaesthetic isoflu-
rane and sevoflurane, by mean of a suitable narcosis gas evapo-
rator.
If these vaporous anaesthetics are used, some method of scaven-
ging the gas from the oxygenator should be considered.
The protocol, the concentration and the monitoring of the anae-
sthetic gases administrated to the patient, is under the sole
responsibility of the physician in charge of the treatment.
WARNING
The only volatile anaesthetics suitable for this use are isofluorane
and sevolfuorane
WARNING
The methods adopted for vaporous anaesthetic gas scavenging
should not increase or reduce in any way the pressure level at the
oxygenator fibres.
F. PRIMING AND RECIRCULATION PROCEDURE
WARNING
Do not use alcoholic priming solutions: such solutions could com-
promise the proper functioning of the oxygenating module.
1) KEEP THE GAS FLOW OFF
2) KEEP THE OXYGENATOR PURGE LINE CLOSED
Check that the blue clamp, placed on the oxygenator purge line, is
in the closed position. Keep the white clamp placed on the recir-
culation line open.
3) SET THE VOLUME OF THE VENOUS RESERVOIR (fig. 1)
Versions with the SOFT VENOUS RESERVOIR
Set the desired volume using the soft reservoir squeezer (ref. 7).
4) ISOLATE THE SOFT VENOUS RESERVOIR AND OXYGENATING
MODULE
Versions with the SOFT VENOUS RESERVOIR
Clamp the cardiotomy outlet, the venous return, the soft venous
reservoir outlet and the arterial outlet of the oxygenator.
Version with RIGID VENOUS RESERVOIR
Clamp the venous reservoir outlet, the oxygenator venous con-
nector and arterial outlet.
5) CHECKING THE HEAT EXCHANGER
Verify again the integrity of the heat exchanger, with particular
attention to possible water leaks.
6) CARDIOTOMY PRIMING
Secure with ties all aspiration lines connected to the cardiotomy.
Fill the cardiotomy with sufficient liquid to ensure the intended
haematocrit is obtained, taking into account:
- the static priming volume of the oxygenator is 105 ml;
- if it is present, soft venous reservoir capacity varies from
minimum 40 to maximum 190 ml;
- the 1/4" tube capacity is 32 ml/m.
7) CIRCUIT PRIMING
Remove the clamp at the cardiotomy outlet.
Versions with SOFT VENOUS RESERVOIR
The priming solution flows to the soft venous reservoir.
The air contained inside the soft venous reservoir will automati-
cally be evacuated from the purge line which is placed at the top
of the reservoir by activating the suction pump. Remove the
clamp placed on the outlet of the soft venous reservoir.
