HIGH FLOW INSUFFLATION UNIT UHI-4
Summary of Equipment Function
This instrument is designed to feed CO
2
inside the abdominal cavity during
endoscopic surgery. The functions of the high flow insufflation unit described
below are enabled only when the specified equipment is connected. For
additional details on ancillary equipment, refer to their specific instruction
manual.
 Cavity mode
Two modes including “Standard” and “Small” can be selected according to the
cavity size (refer to Section 5.3, “Selecting the cavity mode” on page 79).
 Adjustment of the cavity pressure
The pressure inside the cavity can be set in the range between 3 and 25 mmHg
(or max. 15 mmHg in the Small cavity mode (refer to Section 5.4, “Setting the
cavity pressure” on page 80).
 Adjustment of the gas flow rate
The CO
2
flow rate can be set in the range from 0.1 to 45 l/min. (or max. 10 l/min.
in the Small cavity mode). Three flow rate modes including “High”, “Medium” and
“Low” can be selected with a one-touch operation (refer to Section 5.5, “Setting
the flow rate” on page 81).
 Display mode
The items of information displayed on the front panel can be limited as required
by the user (refer to Section 5.7, “Selecting the display mode” on page 83).
 Relief mode
When the cavity pressure exceeds the set value by 5 mmHg or more, the relief
mode is activated to open the channels inside the instrument and release the
internal gas until the cavity pressure drops to the set value. The relief mode can
be set to ON or OFF as required (refer to Section 5.13, “Relief mode” on
page 96). Default set value is OFF.
