To flush the distal catheter:
• Occlude the catheter proximal to the reservoir with finger
pressure, then depress the reservoir.
• Failure of the reservoir to depress easily might indicate distal
catheter blockage.
Note: While proximal pressure is maintained, reservoir will not
refill with fluid.
Note: Flushing the distal catheter cannot be performed with
the right-angle valve configuration.

Appendix A
Optional Manometer Testing
Although Integra does not recommend functional testing, some
surgeons might choose to do so. Before testing, it is extremely
important that a CERTAS Programmable Valve with or without
SIPHONGUARD be flushed of all air bubbles. Air bubbles within
the valve or SIPHONGUARD will produce inaccurate manometer
test results. The presence of air bubbles can reduce the cross-
sectional area of the flow path, increase system resistance, and
impede the flow of fluid through the system during testing.
SIPHONGUARD Functional Testing
Equipment Required (use all sterile equipment, perform testing
under sterile conditions)
One sterile manometer, wide-bore (e.g. 3.5 mm), graduated in
mm (available in lengths from 38 to 60 cm)
One sterile 4-way stopcock
One sterile syringe, 10mL minimum is recommended
One sterile syringe filter, 5 µm
Sterile tubing adapters
Sterile silicone tubing
One sterile male luer connector with 1/16 in. (1.6 mm) barb
Sterile saline solution
Flushing Procedure
Note: At a rate of 0.5 mL/minute, unitized versions require
2–3 minutes to complete flushing. This is the time required for
fluid to fill the valve and exit the distal catheter. Allot additional
time to ensure the system is free of air bubbles.
1 . Fill syringe with sterile saline using the 5 µm syringe filter.
The syringe filter should not be reused in any subsequent
refilling of the syringe. Once the syringe has been filled,
remove the filter from the syringe.
2 . Assemble manometer, stopcock, syringe, and tubing
(Figure A-1).
3 . Adjust the valve setting to 1 while the valve remains in its
sterile package.
