Occluder Module
A Perfusion Screen can be configured to operate 1 occluder. The occluder system
provides a computer-controlled tube clamping mechanism used to control flow in the
venous line.
The occluder display on the CCM displays % open from 0-100% in 1% increments.
The occluder display shows the approximate % that the venous tube is open over the
range from 0% or fully closed to 100% or fully opened in only 1/2 in. (12,7 mm) or
3/8 in. (9,5 mm) I.D. tubing with blood or prime solution. A decrease in the occluder
% will result in a decrease of flow through the venous tube. The display shows a
reference number only for other tubing sizes. Accuracy requires proper calibration
and no backpressure.
The occluder supports tubing sizes in the range of 1/4 in. (6,4 mm) I.D. x 1/16 in. (1,6
mm) wall thickness to 1/2 in. (12,7 mm) I.D. x 3/32 in. (2,4 mm) wall thickness and
fluid temperatures of 20°–40°C. A nominal durometer range of 65-70 Shore A is
recommended.
The occluder can be configured to respond to primary pump events using the
Configuration Screen on the Central Control Monitor. Occluder responses are user
selectable. Valid responses for the occluder are Full Close, Full Open, Go to % Flow,
or No Response.
The occluder slide bar shares a location on the CCM with the gas slide bars. When
operating a device that shares a slide bar location, make sure that the slide bar
displayed is for the device you intend to operate.
Connect Occluder Head
Flexible Mounting Arm
1. Select the desired pole position and secure the flexible mounting arm to the pole.
2. Set the mounting arm to the desired position:
•
Turn the tension control knob counterclockwise to loosen the joints of the mount
arm. Manually support the flexible arm when adjusting the tension control knob.
Do not loosen the knob beyond the stop.
• Position the arm as desired and tighten the tension control knob.
3. Screw the occluder head onto the threaded stud. Make sure the occluder head
is fully installed on the threaded stud. Make sure the occluder head is securely
mounted on the mounting arm.
Note: Always manually support the flexible arm when adjusting the tension control
knob.
