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.

Abstract: A medical remote controller device is disclosed. The device includes a display and at least one input switch dedicated to bolus delivery wherein a bolus delivery is programmed when the input switch receives an input and wherein the number of inputs received by the input switch determines the amount of bolus to be delivered.

Abstract: A method is provided for regulating fluid pump pressures by detecting an elevation differential between a fluid flow control device and the distal end of a fluid line in communication with the fluid flow control device. A fluid flow control device, for instance a peritoneal dialysis device, is at a first height, a distal end of a fluid line is at a second height, and a valved outlet, when open, affords communication between the fluid flow control device and the distal end of the fluid line. The elevation differential is correlatable with a pressure measurable during a calibration procedure provided as a part of the methodology.

Abstract: The present invention involves, in some embodiments, systems and methods for performing an integrity test on a medical grade cassette that is configured to be used on a medical fluid handling system, wherein the cassette may be disposable and may comprise a membrane therein. The test may be configured to determine an error condition, such as detection of membrane leakage above a threshold value, and may in certain cases be implemented by a medical computer system. In certain cases the integrity test is a dry integrity test and in certain cases, the test is configured to determine a leakage rate of fluid through the membrane.

Abstract: The present invention involves, in some embodiments, fluid handling systems and methods for pumping fluid to and from a patient. The system and methods in certain embodiments involve a pumping cartridge and a reusable component configured to mate with the pumping cartridge comprising. The reusable component may comprise a control chamber and a pressure transducer configured to measure a gas pressure associated with the control chamber, and may further include a processor configured to supply the control chamber with a gas at a predetermined pressure, open the pump chamber to the surroundings, monitor the gas pressure associated with the control chamber using the pressure transducer over a predetermined period of time, and determine if the change in gas pressure exceeds a predetermined limit.

Abstract: 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.
