the distal catheter Allot additional time to ensure the system is free of air
bubbles
1.
Assemble the manometer, stopcock, syringe, and tubing (Figure A-1)
Figure A-1
2. Detach the syringe from the assembly and fill the syringe with sterile
saline solution using the 5 µm filter in-line Detach the filter after
filling the syringe
3.
Remove the valve from the sterile package, and connect the valve
to the manometer/syringe assembly Note: Do not attach the distal
catheter at this time
4. Adjust the stopcock to connect the syringe to the valve assembly
(Figure A-2)
Figure A-2
5.
Position the valve vertically to direct the flow of saline upward
through the assembly This orientation aids in flushing air from the
system
6. Using the syringe, gently flush saline through the system while
gently depressing the prechamber to purge air bubbles from the valve
assembly
7.
Attach the distal catheter and continue to flush the system using the
syringe until saline solution exits the end of the distal catheter
Note: An excessive flow rate (>0 75 ml/min) activates the
SiphonGuard Device and creates the impression that the valve
is distally occluded In reality, flow is being diverted to the high
resistance secondary pathway
8.
The device is now ready for the SiphonGuard Device Functional Test or
the Manometer Test.
Note: All valves are susceptible to damage due to excessive flow rate
during testing Take extreme care when flushing a valve as damage
can occur when excessive flow rates are used It is recommended to
use a flow rate of no greater than 0 5 ml/min
SiphonGuard Device Functional Test
Note: This procedure applies only to valves with an integrated
SiphonGuard Device.
Note: Perform this procedure immediately after completing the flushing
procedure This procedure is designed to provide visual confirmation of
proper functioning of the SiphonGuard Device
1.
Use a full syringe of saline solution attached to the 4-way stopcock to
fill the manometer to the top
