ABSTRACT:
The present invention includes a method and apparatus for the testing the integrity of a dialyzer prior to use. The dialyzer is tested on the same hardware used for the treatment of dialysis. The dialysate and blood sides of the dialyzer are primed in the normal manner. The blood and saline lines are clamped while the venous line is vented to the atmosphere. The ultrafiltrate flow rate is increased until the blood side fluid is ultrafiltered. The dialysate side is monitored for pressure increases. If the pressure does not increase, the test fails.
