HIGH FLOW INSUFFLATION UNIT UHI-3
• After connecting the suction tube, automatic suction will start
operating if an additional veress needle or trocar, etc. is
inserted (due to the momentarily high abdominal pressure).
To prevent the suction function from activating, either
disconnect the suction tube, close the stopcock on the trocar
to which the suction tube is connected or press the STOP
switch.
When the abdominal pressure exceeds the set pressure by 5 mmHg, the
excessive pressure warning lamp will light and an alarm will sound. If the
pressure is exceeded for 10 seconds or longer, automatic suction will be
performed until the abdominal pressure drops to the set pressure.
