摘要： A dialysis valve includes a tube attached between an artery and a vein which, when elongated, simultaneously narrows in diameter at at least one location. The narrowed portion of the tube decreases the volume and velocity between the arterial and venous side of the patient to prevent damage or intimal hyperplasia on the venous side between dialysis treatments. When the valve is opened for dialysis, an unrestricted blood flow exists between the arterial and venous side, permitting a controlled, open blood flow during dialysis.

摘要： The present invention involves, in some embodiments, mechanisms and methods of occluding collapsible tubing with an occluder to prevent fluid flow therethrough. In some embodiments, a tube occluding mechanism is disclosed that includes a bendable occluding member for creating a force that can be applied to a collapsible tube to occlude the tube. In some embodiments, the collapsible tube can be an inlet/outlet tube on a removable pumping cartridge that is coupled to a reusable pump drive component when the system is in operation. In such embodiments, the occluding mechanism can be attached to the reusable component and can be used to block fluid flow to and from the pumping cartridge. In some embodiments, the occluding member can comprises a spring plate which can create a force to occlude tubing when in a relaxed, unbent configuration, and which can be bent to unocclude the tubing. In some preferred embodiments, in a default configuration of the tube occluder mechanism (when no external force is applied to the occluding member) the tubes are occluded, so that the tube occluder mechanism provides a fail-safe configuration preventing fluid flow to and from a pumping cartridge to which the tubes can be connected.

摘要： A nasal cannula includes a cannula body having a passageway extending therethrough from a first end to a second end and an airflow restrictor coupled to the cannula body and positioned to selectively restrict air flow through the passageway during exhalation. A flow regulator is settable to a plurality of airflow positions and cooperates with the airflow restrictor to regulate the air flow during exhalation such that the air flow during exhalation is variable in response to the airflow position of the flow regulator. In one embodiment, an airflow restrictor is deformable from an at-rest configuration to an inhalation configuration during inhalation, and exerts a substantially constant backpressure during exhalation for a predetermined range of expiration flow rate. Methods of use are also provided.

摘要： A valve system for use in a system including a first source of a first pressurized fluid and a second source of a second pressurized fluid includes a valve housing including a first inlet port adapted to be placed in fluid connection with the first source, a second inlet port adapted to be placed in fluid connection with the second source and an outlet port. The valve system further includes a backflow prevention system to prevent flow of the first pressurized fluid through the second inlet and to prevent flow of the second pressurized fluid through the first inlet port. The valve system is adapted to provide a fluid path between at least the first inlet port and the outlet port to enable fluid to be drawn from the outlet port to the first inlet port. Several of the valve systems of the present invention provide for flow from the first inlet port to the outlet port and concurrent flow from the second inlet port to the outlet port.
