System Overview
2-12
Air Bubble Detect Module
The air bubble detect module (ABD) is used with an air
sensor to detect air bubbles in the perfusion circuit. Use
only Terumo
®
Sarns
TM
Ultrasonic Air Sensors with the
system.
Up to 4 air bubble detect modules may be connected to
the system at the same time.
The air sensor connects to the module with the air
sensor cable. The air sensor can be mounted directly on
the tubing or on a bracket.
Select the sensor which is appropriate for the tubing size
and flow rate to be used.
Tubing size can be 3/8 in (9,5 mm) I.D. (Inner Diameter) x 3/32 in (2,4 mm) wall
thickness, 1/4 in (6,4 mm) I.D. x 3/32 in (2,4 mm) wall thickness or 1/4 in (6,4 mm) I.D.
x 1/16 in (1,6 mm) wall thickness.
The air sensor detects air bubbles within clear, flexible medical grade polyvinyl
chloride (PVC) tubing in clear priming solutions or blood with a hematocrit from 15%
to 40%.
The air sensor detects air bubbles of 0.3 cc or larger at flow rates up to 3 L/min for
1/4 in (6,4 mm) I.D. tubing and gas bubbles of 0.5 cc or larger at flow rates up to 6
L/min for 3/8 in (9,5 mm) I.D. tubing.
The air bubble detect module only operates in the alarm mode. Pump responses to
an air alarm are selected during configuration.
In the event of an alarm, an audible dual tone alarm sounds, a message appears on
the Central Control Monitor, the appropriate air detect icon on the Central Control
Monitor flashes red, and the status LED on the appropriate air bubble detect module
flashes red. If a safety connection was made to a pump, a message will also appear
on the message area on the pump control panel, and the pump will react with the
response chosen.
Level Detect Module
Always use a level detect module with level sensors to
monitor blood levels in hardshell reservoirs. Use only
Terumo
®
Sarns
TM
Ultrasonic Level Transducers with the
system.
One level detect module may be connected to the
system.
Level sensors are attached to the color coded
connectors on the module and then to a hardshell
reservoir. A yellow alert sensor attaches to the yellow
connector and a red alarm sensor attaches to the red
connector. Level sensors are attached to the hardshell
reservoir with level sensor pads.
