Abstract: A method and apparatus for selectively expressing one or more selected fluid materials out of a fluid container, including a centrifuge rotor having a round centrifuge chamber of selected volume, a round expandable enclosure disposed within the centrifuge chamber having a rotation axis coincident with the central rotation axis and a flexible wall, a pump for controllably pumping a selected volume of expressor fluid into and out of the expandable enclosure wherein the fluid container is receivable with the centrifuge chamber, and a retaining mechanism for holding the fluid container within the centrifuge chamber in a coaxial position. The flexible wall of the fluid container is in contact with the flexible wall of the expandable enclosure.

Abstract: This invention describes a method and apparatus for a liquid dispensing cartridge pump suitable for dispensing reagent in an automatic system. In embodiments, the present invention may include a liquid metering chamber that accurately controls the amount of fluid dispensed. In other embodiments, the amount of fluid may be controlled by the action of a diaphragm, which may be assembled into a cavity of a dispenser housing creating a metering chamber. In another embodiment, the volume created by the metering chamber determines the volume of dispensed fluid. When the diaphragm is compressed from its free or extended state to its inverted state, it may substantially conform to the inner surface of the metering chamber. The fluid enters the metering chamber through an upper unidirectional valve and exits the dispenser housing through a lower unidirectional valve.

Abstract: A fluid delivery device may include a fluid driving mechanism for driving fluid out of a reservoir and an actuating mechanism for actuating the driving mechanism. The fluid delivery device may also include one or more sensors for monitoring operation of the fluid delivery device. The fluid delivery device may also include a chassis providing mechanical and/or electrical connections between components of the fluid delivery device.

Abstract: A peristaltic pump assembly for easy loading includes a pump housing having a curved surface. A stationary tubing manifold from which a loop of tubing extends is positioned in line with the curved surface. A pump rotor rotatable about an axis is positioned adjacent to the curved surface. The rotor has a groove located above the curved surface encircling the rotor for retaining and stretching the loop of tubing in loading position between the rotor and the manifold. During loading, a notch located on the rotor progressively captures and urges the tubing downward between the curved surface and the pump rotor when the rotor is rotated.
