5.5.1 I/A MODE FUNCTIONS
Linear Flow: When position (2) is reached, the
peristaltic pump speed, or Flow (cc/min), is
controlled by the actuation of the foot pedal
between zero and the maximum limit set by the
user using the UP or DOWN arrow keys or the
default setting of the Flow parameter.
The actual Flow Rate display will show the
position of the foot pedal from zero to the preset
Flow Rate value on the console. The foot pedal
has two (2) positions in I/A Mode:
1. Position (1): Irrigation
2. Position (2): Irrigation and Aspiration
Fixed Flow: The Fixed Flow Rate is set by the
UP or DOWN arrow keys of the Flow (cc/min.)
parameter.
Once the foot pedal reaches position (2), the
Flow Rate will be equal to the preset value.
Linear Vac: The user has the ability to hold the Vacuum by holding the foot pedal main treadle in
place. After a period in time, this will cause the peristaltic pump to cease, and a message will be
displayed on the screen stating that the “Pump has Stopped”. Fully depressing the foot pedal will
result in continuous Irrigation and Aspiration. Releasing the foot pedal will cease the Irrigation and
Aspiration functions.
Fixed Vac: The Vacuum (mmHg) UP or DOWN arrow soft-keys on the console set the Vacuum
value to a user-defined limit or default factory limit. The user cannot stop the Vacuum in Foot
Pedal position (2). The Vacuum will increase until the preset value is reached; the peristaltic pump
will stop and the “OCCLUSION” alarm will sound.
Reflux: The “Reflux” function is normally used to clear lens material from the aspiration tube of
the ultrasonic handpiece when it becomes occluded. Reflux is available in all functions.
The foot pedal has the Reflux (default) position on the “Right Side Kick Switch”.
To activate the Reflux function, press and hold the Right Side Kick Switch. The Reflux function
may have to be performed a few times depending on the occlusion.
