Operation Procedure
During Circulation
• The measured flow value is displayed numerically on the LCD and Control panel. It is also displayed as a bar indication on the
LCD. The response of the numerical indication is slower to improve the display stability.
When an alarm is issued, the alarm message is displayed on the message area.
(For details, refer to “List of Alarm Messages” (page 134).)

Warnings
• Monitor the circulation status (the operation status of the system, blood storage state of a reservoir, etc.) during
extracorporeal circulation without fail. 1. As this system does not have a function to monitor the status of the patient, the
system cannot detect when the status of the patient changes even if the system operates properly. 2. The system cannot
detect the leakage of liquid (including blood) caused by damage to the extracorporeal circulation circuit. 3. It is possible
that the system will not detect a flow abnormality, even if the ABD/Flow Sensor is used. 4. This system may not operate in
accordance with the specifications if the system is used together with another system.
• Do not clamp the blood inlet line of the centrifugal pump during circulation. Air bubbles may occur in the blood as the inside
of the centrifugal pump is negatively pressured.
• Avoid sudden temperature changes even when operating within the systemʼs indicated temperature specifications.
Condensation inside the system results in damage, time degradation, and decreased performance.
• When the Controller is transported while in use, do not touch the buttons, etc. inadvertently or use the key lock function.
Otherwise it may result in an unintended operation (stop, start, power on/off).
Cautions
Note
• Perform the flow adjustment by changing the motor speed of the centrifugal pump. If the adjustment is performed by
partially clamping the blood outlet line of the centrifugal pump, damage to the blood may be increased.
• While circulating, maintain the motor speed at a speed higher than that at which the Low Flow Alarm is issued (the speed
at which back flow does not occur due to the height gradient or the patient
ʼs blood pressure). Back flow of blood may
occur.
• When circulating or priming, if a significant amount of air enters the centrifugal pump causing the pump to idle and
circulation to stop, perform the following procedures: After clamping the blood outlet line of the centrifugal pump, stop the
rotation of the pump. Remove the air and release the clamp to restart circulation.
• Be cautious in motor speed adjustment when decreasing the motor speed of the centrifugal pump. Back flow of blood may
occur.
