must be secured by means of ties.
• Remove the yellow label (labelled with
"Remove before use") and the yellow cap
from the VENT/VACUUM connector.
• Before use remove from the pressure relief
valve the yellow tab (labelled with "Remove
before use").
• The action of the pressure relief valve does
not prevent from excessive negative pressure
in the reservoir caused by sudden abnormal
high vacuum level (i.e. vacuum regulator
device failure).
• Do not for any reason occlude the external
access hole of pressure relief valve.
VENOUS LINE: Connect a 1/2" venous line to the
reservoir venous inlet port marked "VENOUS
RETURN".
The venous inlet port can be rotated through
360° to find the most convenient position for the
venous tube.
ASPIRATION LINES: After removing the
protective caps from the filtered inlet ports
on the top of the cardiotomy/venous reservoir,
connect the ends of the aspiration lines and turn
the turret orienting the filtered inlets towards the
suction pumps.
PUMP LINE: The pump segment must be fitted
between the venous reservoir outlet port and the
oxygenator venous inlet port, taking account of
the pump rotation direction.
Connect the oxygenator purge line to the top of
HORIZON CVR (turrets).
4) SAMPLING MANIFOLD
The arterial/venous sampling manifold is
positioned on the venous reservoir lid.
If you wish to take samples from a more remote
position, remove the manifold from the fastening
guide, fit it on the dedicated holder and unwind
the tubing provided. In this position, arterial/
venous sampling can be performed in a radius
of about 1 meter. After perfoming artero/venous
sampling, Eurosets recommends to maintain
the three stopcocks of the manifold in the
open position thus to allow an artero/venous
loop during ECC, permitting a representative
sampling of the perfusion status.
CAUTION
The user should check for occlusions in tubing
during set up.
5) CONNECTING THE TEMPERATURE PROBE
The venous temperature probe port is positioned
on the venous inlet port of the reservoir.
6) CONNECTING THE VACUUM LINE
If performing
(VAVD), please read carefully section L of these
instructions for use.
H. PRIMING PROCEDURE
WARNINGS
• Do not apply the vacuum during this procedure.
• Do not use alcohol-based priming solution, as
this would compromise proper functioning of
the device.
1) CLOSE THE VENOUS LINE
Clamp the venous line leading from the patient.
2) PRIME THE VENOUS RESERVOIR
Close all the aspiration lines with clamps and
secure with ties all aspiration lines connected to
the turrets. Fill the cardiotomy/venous reservoir
with sufficient priming solution to ensure that
the intended hematocrit is obtained, taking into
account that:
• the 3/8" tube capacity is 72 ml/m;
• the 1/2" tube capacity is 127 ml/m.
Eurosets suggests to perform priming through
one of the cardiotomy turret ports.
Clamp the cardiotomy/venous reservoir outlet.
3) PRIME THE OXYGENATOR, FOLLOWING THE
INSTRUCTIONS FOR USE OF THE OXYGENATOR
IN USE
Remove the pump segment of the arterial pump
head and position it at the same height as the
cardiotomy/venous reservoir. Slowly open the
clamp at the reservoir outlet and fill the tube,
gradually lowering it with respect to the level
in the cardiotomy/venous reservoir, so that it is
completely filled and all the air is sent to the
oxygenator. The oxygenator module is hence
completely filled by gravity. Once oxygenator is
completely filled, position the pump segment in
the arterial pump and start recirculation.
WARNING
• Do not use pulse flow during priming.
• Sudden changes in flow rate during priming
can pull air across the membrane into the
blood pathway.
• Check the correct dosage of anticoagulant in
the system before starting the bypass.
