4.4 AUTOMATIC LOW/ HIGH FLOW SWITCHING
If automatic switching is selected from the menu, the device starts insufflating in low-flow mode, then switches
to the high-flow position once blow-off pressure is reached.
4.5 EXTERNAL PRESSURE RELIEF VALVE
Our insufflators have a valve that allows CO2 overpressure outside the device in order to avoid:
• over-pressurization in the pneumoperitoneum (if the pressure is more than 5mmHg greater than the blow-off
pressure for more than 3 seconds)
• any return of fluid to the device’s interior, thus preventing any risk of deterioration or contamination.
4.6 MONITORING OF THE CYLINDER PRESSURE
This last generation of insufflators is equipped with a system for measuring the cylinder pressure which is
continuously displayed. Moreover, when the cylinder pressure reaches 40 bars, a cylinder icon is displayed
on the LCD and “cylinder empty” blinks. As soon as the cylinder pressure reaches 20 bars, the insufflator
informs the user via:
• The display of the cylinder pressure in the alarm area
• A red light on the display
Below 10 bars the insufflator is not allowed to be used.
4.7 LCD DISPLAY
In order to communicate better with the user and to improve the ease of use, we have equipped our latest
generation of insufflators with a 5.7-inch LCD display.
This allows the following to be displayed in 5 different languages:
• warnings and error messages in full
• interactive menu allowing the device to be personalized
• indication of empty cylinder
• indication of blow-off pressure in mm Hg
• indication of intracavitary pressure in mm Hg
• indication of flow in l/min
• indication of volume of CO2 used in liters
• indication of status: in start/stop and “high flow”/“low flow”
• moving around in the menu by means of a selection thumbwheel
4.8 FILTER
• CO2 cylinder
A particle filter is inserted in the CO2 inlet to prevent contamintaion arising from particles or impurities which
may be present in the CO2 from entering cylinders.
• Patient
In order to guarantee patient safety, it is essential to use disposable sterile tubing sets with a
moisture-repellent viral filter supplied with the insufflator and to replace it for each patient.
