Checking the device
NOTE!
Checking the device
This test can be conducted with the tube set and cannula that will be used for the
procedure. Consider sterile/non-sterile aspects during handling.
1. The device is switched off, no tube set is connected.
2. Make sure the gas supply is connected and open.
3. Use the ON/OFF switch to turn the device on. The device now conducts an
automatic self-test.
4. Select the operating mode (e.g. Pediatric).
5. Under consideration of sterile/non-sterile aspects open the package of the in-
sufflation tube set that will be used for the procedure. Connect the tube set to
the device.
6. Attach the insufflation tube to the cannula and close the stopcock.
7. If the gas consumption display field (see Chapter Gas Consumption Display
[}39]) depicts a value, press the button to reset the display to zero
0

L
.
8. Select a nominal pressure of 8mmHg and a gas flow of 2l/min.
9. Start insufflation: Press the
START
button.
10. Insufflate approximately 30seconds. The display status line depicts
Occlusion
after maximum 4seconds.
11. Stop insufflation: Press the
STOP
button.
WARNING!
Leak in system
If the actual gas consumption is higher than 0.4l, there is a leak in the system. If
this is the case, use steps 12 to 14 outlined below to locate the leak.
12. Repeat steps 7 to 11 without cannula and with closed tube end. The previously
connected cannula has a leak if gas consumption is now below 0.4l.
13. Repeat steps 8 to 12 with a new tube if another leak becomes apparent. If the
gas consumption is now below 0.4l, the previously used tube set has a leak.
14. If another leak is detected, this leak is then directly within the device. Make
sure the device can no longer be operated until an authorized service techni-
cian conducts the appropriate checks.
