6.3.3 Dynamic Pressure Scanning (DPS)

During the infusion, the bottom-right corner of the Run screen demonstrates
real-time pressure changes of the animal, in order to find the tube occlusion at an
earlier time and to prevent the occurrence of further complications.

6.3.4 Automatic Pressure Release Function (Anti-Bolus)

When occlusion occurs, infusion will stop and the [Occlusion] alarm will be
triggered. After the alarm is triggered, the motor is reversed, and the cannula
pressure is then released. This prevents an additional aggressive dose to the animal
after the occlusion is eliminated.

6.4 Set Air Detection

Air bubble size indicates the size of air bubble that can be monitored in the tube.
The lower of the bubble size, the smaller air bubble can be identified. Bubble in the
infusion tube can be measured by the built-in ultrasonic sensor, bubble size can be
calculated by the internal CPU, which is compared with the preset threshold. [Air in
line] alarm will be triggered if bubble size exceeds the threshold.
1. Select [Main Menu]→[General Options]→[Air detection].
Select [Air detection], 6 levels of air detection can be selected, lowest at 20μl,
2.
and highest at 800μl. Air detection level should be selected according to actual
needs.
CAUTION

If the animal experiences discomfort or danger at a higher air bubble filter
level, monitor the animal's physical conditions and select the actual
needed level. Measures should be taken instantly if any abnormal
condition occurs.

6.5 Accumulate Air

1. Select [Main Menu]→[General Options]→[Accumulate air].
2. Select [Accumulate air]: 0.1-4ml is adjustable.

6.6 Drip Setting

1. Select [Main Menu]→[General Options]→[Drip setting].
Select [gtt/min]→[On], and set the "Drip". On infusion parameters setting
2.
interface of Rate Mode and Time Mode, "ml/h" and "gtt/min" can be switched. If
[Off] is selected, "ml/h" and "gtt/min" can not be switched.
