摘要:
The present invention involves, in some embodiments, systems and methods for pumping fluid into or out of a patient via a cartridge. The cartridge may include a membrane defining a chamber and mechanisms to supply, measure and control pressure in the chamber. The system further includes a processor that can be configured to compare certain pressure measurements to each other to facilitate determining if an error condition exists in the medical system if the difference between measurements is greater than a threshold. In certain cases the error condition may indicate leakage of the membrane, for example due to a pinhole in the membrane.
