  • Patent number: 8989906
    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.

  • Publication number: 20140288490
    Abstract: A method for delivering a target volume of fluid to a destination is provided. The method includes delivering a first volume of fluid to the destination in increments each having approximately a first incremental volume, the first volume of fluid being less than the target volume and delivering a second volume of fluid to the destination in increments each having approximately a second incremental volume, the second incremental volume being less than the first incremental volume, such that the sum of the first volume and the second volume is approximately equal to the target volume.

  • Publication number: 20140286794
    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.

  • Publication number: 20140276428
    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.

  • Publication number: 20140260556
    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.

  • Publication number: 20140260551
    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.

  • Publication number: 20090254037
    Abstract: A system for pairing a controller and an infusion pump is disclosed. The system includes an infusion pump, a controller device and a user interface residing on both the infusion pump and the controller. The user interface includes a pairing mode for enabling wireless communication between the infusion pump and the controller device, wherein the user interface requires both the infusion pump and the controller to be in the pairing mode simultaneously. Also, a method of changing a power source in an infusion pump is disclosed. The method includes placing the infusion pump in idle mode wherein the infusion pump stops delivery. Removing the first power source from the infusion pump. Replacing the first power source with a second power source in the infusion pump, and maintaining the insulin on board during the changing of the first power source with the second power source.
