  • Patent number: 6872358
    Abstract: Devices for dispensing test strips and methods of using the same are provided. The subject devices are characterized by having a housing made of a cover and a base configured to retain a plurality of test strips. In certain embodiments, the height of the base is less than the height of each of the test strips, such that a portion of each of the test strips extends beyond the distal or top edge of the base. The subject devices may further be characterized as having a substantially air and moisture tight seal. In using the subject devices, a plurality of test strips stored in a subject device are provided. A single test strip is removed from the subject device by moving the test strip distal to the remaining test strips. Also provided by the subject invention are kits for use in practicing the subject methods.

  • Publication number: 20040219691
    Abstract: A test strip for use in the detection of an analyte (e.g., blood glucose) in a liquid sample (e.g., a whole blood sample) includes a base support layer and a reagent pad disposed on the base support layer. In addition, at least a portion of the base support layer in proximity to the reagent pad is formed of a clear material such that a user can perceive the liquid sample through the base support layer during application of the liquid sample to the reagent pad. The test strip optionally includes a reservoir for restraining excess liquid sample. The reservoir can be defined by hydrophilic and hydrophobic regions of the base support layer or by base support ridges that circumscribe the reagent pad. Also a test strip that includes a base support layer with a raised reagent pad platform, a reagent pad disposed on raised reagent pad platform and an upper layer disposed above the base support layer.

  • Patent number: 5912134
    Abstract: A cartridge is provided to present a biological sample for analysis by an imaging instrument. The cartridge of the invention utilizes a series of channels, capillaries, reservoirs and stop junctions to precisely move a sample, reagent and diluent through the cartridge as a function of the sum of capillary, gravitational and low centrifugal forces. The operator applies a precise amount of sample to the cartridge; therefore, the cartridge fluidics need not meter the sample prior to dilution. A practical and cost effective cartridge and assay process is disclosed which overcomes many of the limitations of the prior art. Such a cartridge is especially useful with fixed volume assays which permit low centrifugal accelerations to move the fluids within the cartridge.

  • Patent number: 5547849
    Abstract: The apparatus and method of the present invention disclose a scanning imaging cytometer wherein an unprocessed biological fluid sample is reacted with a fluorescently-labeled binding agent. The reacted sample undergoes minimal processing before it is placed into a capillary tube. The sample is optically scanned and fluorescence excitation is recorded from a plurality of columnar regions of the capillary tube, each columnar region generally defined by the spot size of the excitation beam and the depth dimension of the capillary tube. A spatial filter of a sufficient pinhole diameter is selected to allow simultaneous volumetric detection of all fluorescent targets in each columnar region.

  • Patent number: 5338427
    Abstract: A disposable cartridge for a capillary electrophoresis instrument in which short capillary tube segments are used for simultaneous multiple lane separations. The cartridge contains all separation components of the instrument which come in contact with the sample and is capable of automatically loading a quantitative portion of a bulk sample into the capillary tube segments. Electrophoresis occurs without bulk flow through the capillaries, which are scanned in situ by the instrument.
