• High-pressure discharge valve
If excessive pressure is created in the high-pressure regulator, a safety valve is available to limit
the risks.
• Bacterial filter
This filter, which is delivered assembled on the sterile disposable tubing hose, limits the risk of
cross-contamination between patients.
In this mode, the insufflation flow rate is limited to 2 l/min to create the pneumoperitoneum.
This flow rate is not sufficient to regulate the pressure inside the cavity in the event of substantial
escape of gas and it will therefore be necessary to change to the high flow rate.
By default, the insufflator starts in low flow mode. The surgeon can choose between manual and
automatic mode to activate the high flow rate.
When the pneumoperitoneum is created, activating this mode enables a maximum flow rate of
up to 45 L/min to be reached. This capacity is then used to compensate for all types of leakage.
It is advisable not to use Veress needles in this mode.
If the automatic change-over switch is set to "ON" in the settings, the device begins to insufflate
in low-flow mode, and then changes to high-flow mode once the pressure setpoint has been
established in the cavity.
Our insufflators are equipped with a valve for releasing excess CO2 pressure from the device
so as to avoid:
• Excessive pressure in the pneumoperitoneum
• Any backflow of fluid inside the device, and in this way avoid any risk of deterioration or
contamination.
