Drip sensor
Drip chamber
•
Squeeze the drip sensor with your fingers and attach it
between the drip opening of drip chamber and surface of the
solution.
Checks
• As shown in the diagram left, attach the drip sensor in the correct position and
direction.
• Attach the drip sensor so that the drip chamber is vertical.
• Place in a position where the drip sensor is not exposed to direct sunlight.
Warning
• When the drip sensor is attached, an alarm will be issued if a free flow is detected. However, the drip sensor does not have
a function to stop the free flow. If the drip in the drip chamber is a continuous flow, abnormal flow rate cannot be detected.
Check that the solution is correctly delivered at the start of and during solution delivery.
Cautions
• The drip sensor detects dripping in the drip chamber with its light sensor. If not correctly attached, it cannot detect dripping
normally and a Flow Rate Abnormality alarm may be issued resulting in the pump stopping. Also even if the setup is
performed correctly, abnormal flow rate or free flow may not be detected in some cases.
• Be sure to turn off the power before connecting/disconnecting the plug of drip sensor to/from the drip sensor connector. If
the plug of the drip sensor is disconnected from the drip sensor connector during solution delivery, Drip Sensor Dislocation
error will be issued and the pump will stop.
• When using low- or high-viscosity drug solution (e.g. glucose injection), this product may issue a Flow Rate Abnormality
alarm and stop operation of the pump even when the state of solution delivery is normal.
• Do not use any drip sensor other than that included. Otherwise drip detection or function of alarms cannot be guaranteed.
The sensor is too
close to the surface
of solution and counts
the drops bouncing
on the surface.
The sensor is too
close to the drip
opening and counts
the drops before
dripping.
Drops run on the
chamber and cannot
be detected.
The sensor part is
overlapping the surface
of solution.
The sensor cannot
count due to the
drip sensor being
exposed to sunlight.
The sensor cannot
count below the
surface of solution.
Dripping cannot
be detected due
to contamination
of the drip chamber.
