摘要:
The present invention involves, in some embodiments, medical systems for pumping fluid using a medical-grade cartridge configured for use in a reusable fluid medical apparatus to move liquids through the cartridge. The cartridge includes a membrane defining a chamber. The system includes a pressure source able to be placed in pneumatic communication with the chamber to adjust gas pressure therein. The system further includes a processor configured to perform a dry integrity test based on adjustment and measurement of fluid pressures in the chamber in which neither side of the member is exposed to liquid during test to determine whether a fluid leak exists through the membrane.
