Special Features; Controls From The Video Camera Head (S397 Only); Autonomy Function With Gas Cylinder; Greater Safety Of Use - SOPRO COMEG 640-45L Manuel D'utilisation

A. CONTROLS FROM THE VIDEO CAMERA HEAD (S397 ONLY)
From one of the three programable buttons located on the camera head, it is possible to control the following functions of the S640 insufflator:
START (in low flow mode), HGH FLOW, STOP
A special communication cable must be connected between the S397 and the S640 ( See S397 user manual for more information).
B. AUTONOMY FUNCTION WITH GAS CYLINDER (NOT AVAILABLE ON ALL MODELS)
This patented function gives the Remaining Time Autonomy (RTA) of the CO2 cylinder. It helps the surgery team to better manage:
- the surgery timing,
- the bottle exchange.
The autonomy appears when the CO2 cylinder pressure will be below 33 bar and when the autonomy will be equal or below 99 minutes.
When autonomy will be equal to 20 minutes 4 sound alarms will warn the surgery team and thus every 5 minutes until the end.
Autonomy can remain at a fixed value during a short or a long period, it will depend on many parameters.
C. GREATER SAFETY OF USE
• Pre-heating system
Heats the gas inside the device.
• Autotest
Automatic calibration of the device and control of its basic components in less than one second.
• Detection of tubing
The device will only start if a tube is both connected to outlet and external pressure relief valve (for safety reasons it is impossible to connect a single tube)
• Automatic regulation of the flow rate
This insufflator automatically regulates the flow rate to maintain an abdominal pressure equal to the pressure setting.
• An additional pressure sensor
If the measurement circuit fails, consistency of the measurements is continuously monitored; this means that the insufflation cycles can be interrupted if there
is the slightest cause of doubt.
• A high-pressure relief valve
If over-pressurization occurs at the level of the high pressure regulator, a safety valve is available to limit any risk.
• Bacterial filter
Delivered inside the disposable tubing, this filter prevents risks from the insufflator to the patient
D. LOW FLOW
In this mode, the insufflation flow is limited to 2 l/min so as to create the pneumoperitoneum. This flow is not sufficient to regulate intracavitary pressure in the
event of major leakages, switch in this case to high flow mode.
By default, the insufflator starts in low-flow manual mode. The surgeon can choose the automatic or the manual mode to activate the high flow.
E. HIGH FLOW
When the pneumoperitoneum is created, activating this mode permits a maximum flow between 20 and 45l, depending on the model. This capacity then makes it
possible to compensate for any type of leakages.
LOW/HIGH
F. AUTOMATIC
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.
G. EXTERNAL PRESSURE RELIEF VALVE
Our insufflators have a valve that allows CO
• Over- pressurization in the pneumoperitoneum if the pressure is more than 2 mmHg greater than the pressure set for more than 1 second and/ or if the pressure
is more than 5 mmHg greater than the pressure set for more than 3 seconds.
• any return of fluid to the device's interior, thus preventing any risk of deterioration or contamination.
