Abstract: A device includes a plasma separation membrane, a capillary channel positioned adjacent the plasma separation membrane to receive plasma from blood placed on the plasma separation membrane, at least one cuvette coupled to the capillary channel, a gas permeable membrane, and a distribution channel coupled to the capillary channel to provide plasma to the cuvette, wherein the cuvette is configured to hold an amount of plasma with reagent suitable for colorimetric assay by a tester to hold the device. Variations include the use of a quantitation channel to provide a selected amount of plasma and a mixing channel to mix plasma with a diluent.

Abstract: A test cartridge includes an input channel to receive a liquid sample to be tested. A sample chamber is coupled to the input channel to receive the sample. An air permeable membrane is coupled between the sample chamber and ambient to prevent passage of the sample past the membrane and stop movement of the sample in the sample chamber.

Abstract: A multiple layer test card including an input channel formed in a layer of the test card, an output channel formed in another layer of the test card, and a filter coupled between the input channel and the output channel to receive fluid from the first channel and collect white blood cells such that the collected white blood cells are optically visible proximate a first surface of the filter.

Abstract: A disposable blood analysis cartridge for analyzing a blood sample including an optical absorbance measurement channel is described. The optical absorbance measurement channel includes a plasma separation region and at least one sub channel including a cuvette that is in fluid communication with the plasma separation region and configured to receive a plasma portion of a blood sample that has been passed through the plasma separation region. A negative pressure may be applied to the cartridge to draw the sample through the plasma separation region and into the sub channel including the cuvette.

Abstract: Methods and apparatuses are provided for an electrical device that employs a feedthrough including a hermetic seal that seals an interior region of the electrical device. The electrical device includes an electrical contact disposed within the interior region of the electrical device, and a wire terminal that includes an encircled portion that is encircled by the feedthrough, and a first end that electrically connects with said electrical contact. When the electrical device is constructed, the first end of the wire terminal is coated with a conductive metal that is more resistant to oxidation than the wire terminal. The first end of the wire terminal is secured to the electrical contact using a mechanical device such as a crimping connector or a spring connector.
