Abstract
The present invention involves, in some embodiments, systems and methods involving fluid handling apparatus for pumping fluid to and from a patient, which may include a reusable component and a disposable pumping cartridge. The reusable component may comprise a control chamber and a pressure transducer configured to measure a gas pressure associated with the control chamber, as well as a processor. The processor may be configured to supply the control chamber with a gas at a predetermined pressure, monitor the gas pressure associated within the control chamber with the pressure transducer over a predetermined period of time, and determine if the change in gas pressure associated within the control chamber exceeds a maximum allowable predetermined limit.
