METHOD FOR TESTING DIALYZER INTEGRITY BEFORE USE

摘要

The present invention includes a method and apparatus for testing the integrity of a dialyzer (12) prior to use. The dialyzer (12) is tested in the same way as when used in the treatment of dialysis. The dialyzer (12) is primed in the normal manner. The arterial blood line (16) is clamped while the venous line (18) is vented to the atmosphere (44). The ultrafiltrate flow rate through dialyzer (12) is increased until a rate is achieved, so that blood passing through would be ultrafiltered. The dialyzer (12) is monitored for pressure increases. If the pressure does not increase the test fails.
