WARNING
• Periodically check functioning of the vacuum
regulating device and the degree of vacuum.
TRILLY PAEDIATRIC AF REPLACEMENT
A spare device must always be available during
perfusion.
After 6 hours of use with blood or if the perfusionist
is of the opinion that the conditions are such that
the safety of the patient may be compromised
(insufficient oxygenator performance, leaks,
abnormal blood parameters, etc.), replace the
oxygenator following the instructions below
CAUTION
Use a sterile technique throughout the replacement
procedure.
1) Suspend the application of vacuum to the
cardiotomy/venous reservoir (when vacuum-
assisted drainage has been used).
2) Turn off the gas flow.
3) Close the venous return line using two clamps (5
centimetres apart).
4) Stop the arterial pump and close the arterial line
using two clamps (5 centimetres apart) near the
oxygenator.
5) Turn off the thermocirculator, clamp and
remove the water lines.
6) Disconnect the gas line, all the monitoring and
sampling lines, and the aspiration lines.
7) Cut the venous return line and the arterial line
at the point between the two clamps, leaving a
sufficient length of tubing to allow reconnection.
8) Remove TRILLY PAEDIATRIC AF from the holder
and remove the pump segment from the arterial
pump.
9) Place a new TRILLY PAEDIATRIC AF on the
holder. Connect all the lines (venous line to the
cardiotomy/venous reservoir, arterial and gas
lines to the oxygenator, pump segment of the
cardiotomy/venous reservoir to the oxygenator,
and possible vacuum line to the cardiotomy/
venous reservoir.
WARNING
• In this phase, keep the venous and arterial lines
clamped.
10) Connect the water lines, turn on the
thermocirculator and check the integrity of the
new TRILLY PAEDIATRIC AF.
11) Fill the cardiotomy/venous reservoir of the new
TRILLY PAEDIATRIC AF with priming solution
through one of the turret ports (1/4" or 3/8").
12) Prime the new TRILLY PAEDIATRIC AF and
evacuate the micro air bubbles as described in
the priming and recirculation procedure.
13) Check all the connections and secure them with
clamps.
14) Remove the clamps from the venous and the
arterial lines, close the purge line and restart
the bypass.
15) Turn on the gas flow and adjust gas flow rate as
required.
16) The residual blood in the replaced cardiotomy/
venous reservoir may be recovered by
connecting the outlet to the 3/8" inlet on the
turret of the new cardiotomy/venous reservoir.
17) The blood contained in the oxygenator and in the
heat exchanger may be recovered by connecting
the arterial line outlet to the 3/8" inlet on the
turret of the new cardiotomy/venous reservoir.
Replacing only the oxygenator module
1) Suspend the application of vacuum to the
cardiotomy/venous reservoir.
2) Close the gas flow and disconnect the gas line.
3) Clamp the venous return line.
4) Stop the arterial pump and close the arterial line
with two clamps (5 centimetres apart) near the
oxygenator.
5) Close the oxygenator inlet line near the
oxygenator module port with two clamps (5
centimetres apart).
6) Turn off the thermocirculator, clamp and
remove the water lines.
7) Close the purge clamp and the cardioplegia line
using a metal clamp where necessary.
8) Cut the lines at the point between the two
clamps.
9) Make sure that the sampling manifold is closed
and disconnect the arterial sampling line being
careful not to contaminate the luer lock of the
sampling manifold (i.e. by connecting it to a
female luer lock positioned on the top of the
reservoir).
10) Remove all the other monitoring lines.
11) Cut the oxygenator inlet line and the arterial line
at the point between the two clamps, leaving a
