Installing Tubing
WARNING:
Tubing must not be reversed in the pump head as air embolism may
occur.
WARNING:
Make sure tubing is properly aligned before closing tube clamp.
WARNING:
The pump must be in Stop mode during tubing installation as
accidental starting of the pump could injure the operator and may damage the
tubing or the pump.
WARNING: Use only medical grade PVC or medical grade silicone tubing
specified for this system.
WARNING: Improperly installing tubing can cause Pump Jam errors. See Insert
Tubing in the Pump section.
Note:
It is recommended that an arterial line filter or similar air barrier device be used
in the extracorporeal circuit.
Select Tubing
Use flexible medical grade polyvinyl chloride (PVC) or medical grade silicone tubing
that is appropriately indicated by the tubing manufacturer for use in roller pumps.
Note that silicone tubing has been tested only as a roller pump boot (the tubing
placed within the roller pump).
For a large roller pump, select tubing with a maximum outer diameter of 11/16 in.
(17,5 mm) and wall thickness range of 1/16-3/32 in. (1,6-2,4 mm). For a small roller
pump, select tubing with a maximum outer diameter of 9/16 in (14,3 mm) and wall
thickness range of 1/16-3/32 in. (1,6-2,4 mm). A nominal durometer range of 65-70
Shore A is recommended.
Verify that the tubing meets any additional specifications listed for specific features,
such as checking that the tube size is appropriate for the air sensor being used.
Insert Tubing in the Pump
Determine whether the pump will be used for suction or perfusion. Verify that the
default forward direction for each pump matches the system direction by checking the
circular arrow on the pump control panel. To change the roller pump default forward
direction, see the
Change Pump Default Direction
section.
• For perfusion, install the tubing with the cannula on
the outlet side of the pump head when the pump
operates in FORWARD.
• For suction, install the tubing with the suction tip
on the inlet side of the pump head when the pump
operates in FORWARD.
To insert tubing:
1. With the pump in Stop mode, lift the pump safety
cover.
2. Turn the occlusion knob clockwise until the space
between the pump raceway and the rollers will
accommodate the tubing.
3. Position the pump section of the tubing above the
pump head so that it follows the curve of the raceway.
4. Turn the universal tube clamp dial until the inlet side
mechanism locks open.
