  • Patent number: 9417235
    Abstract: An object is to provide an optical measurement apparatus for performing an efficient test by optical measurement without incurring incorrect measurements. To this end, the measurement apparatus utilizes a test instrument mounted thereto and including a carrier with a reagent retaining portion for application of a sample. The measurement apparatus includes a reader for color development at the reagent retaining portion, and a controller for driving control of the reader and for required determination. The controller performs the determination by utilizing the data obtained by reading the color development of the reagent after a reaction completion period Tr1-Tr6 depending on the reagent and starting from the mounting of the test instrument. When detecting that the color development at the reagent retaining portion is completed before the lapse of the reaction completion period Tr1-Tr6 after the mounting of the test instrument, the controller stops the test for the test instrument.

    Abstract: A method of determining concentrations of a plurality of analytes from a single blood sample placed in a single opening. A portion of the single blood sample is absorbed by a test matrix that includes a plurality of layers and a chromogenic agent. A colored response is generated by the test matrix. The colored response is proportional to the concentration of a first analyte. A portion of the single blood sample is drawn into a capillary tube and placed in contact with an electrode and a counter-electrode. An electrical property of the single blood sample is analyzed through the electrode and counter-electrode. The electrical property is proportional to the concentration of a second analyte in the single blood sample.

    Abstract: An assay system designed to detect a protein biomarker in urine that is diagnostic for interstitial cystitis (IC). The presence of a 9 amino acid glycopeptide, antiproliferative factor (APF), in urine is unique to patients with IC. Urine samples from patients who exhibit symptoms consistent with IC are added to the assay system. Binding of APF to the cytoskeletal associated protein 4 (CKAP4) is positive for the presence of APF in urine and diagnostic for IC. The diagnostic system is a significant and surprising advance in diagnosis of IC and has commercial applications relevant to women and men who suffer from symptoms consistent with IC.

  • Patent number: 8221333
    Abstract: A puncturing system includes a support tape (1) that supports a plurality of lancets (2), a first reel (3) onto which the support tape (1) with unused lancets (2) is wound, a second reel (4) on which portions of the support tape with used lancets (2) are to be wound, a winding mechanism which, by turning the second reel (4), brings the lancets (2) supported by the support tape (1) to a position of use one after another and thus unwinds the support tape (1) from the first reel (3) and winds it onto the second reel (4), and a puncturing drive mechanism (7) with which lancets (2) located in the position of use are accelerated in order to puncture the skin. The support tape (1) between the first and second reels (3, 4) is twisted only in one direction of rotation by at least a quarter turn, preferably by at least a half turn.

  • Patent number: 8202488
    Abstract: A system for analyzing the concentration of an analyte in a fluid sample comprises a test strip and a meter. The test strip is capable of being inoculated by the fluid sample. The test strip includes a test element, which contains at least one reagent adapted to cause a reaction when brought into contact with the analyte. The meter includes a read-head, a repositioning device, and a display. The read-head is capable of producing a signal indicative of the reaction between the analyte and the at least one reagent. The display being capable of displaying the analyte concentration. The repositioning device is adapted to move the test strip from a loading position to a testing position. The testing position positions the test element proximate to the read-head.

  • Patent number: 8196374
    Abstract: A lancet integrated test element tape includes a plurality of lancet integrated test elements. The lancet integrated test elements each include a lancet configured to form an incision in tissue and a test element configured to analyze body fluid from the incision in the tissue. A cartridge includes a supply compartment configured to store an unused section of the tape. The tape is folded within the supply compartment to limit damage to the lancet integrated test elements. The cartridge can further include a waste compartment in which a used section of the tape is stored. An indexing mechanism moves the tape between the supply and waste compartments.

  • Patent number: 8178351
    Abstract: A container with a rotatable lid for reading and handling diagnostic reagents in tape form comprising a body portion, a lid portion, a continuous tape, a reagent-sensing device, and a storage device. The body portion includes an inner and outer surface. The lid portion is attached to the body portion and is adapted to rotate from a closed position to an open position. The continuous tape includes a diagnostic reagent. The reagent-sensing device is attached to either the body portion or the lid portion and adapted to read the diagnostic reagent. The storage device is attached to the body portion that is adapted to hold and dispense an unused portion of the continuous tape. During the rotation of the lid portion, the continuous tape is advanced from the first storage device and is extended over the reagent-sensing device.

  • Patent number: 8147426
    Abstract: A system for diagnostic testing may include a meter for performing a diagnostic test on a sample applied to a test media and a container configured to contain test media compatible with the meter. The meter may include a closure portion for selectively closing the opening of the container. The system may also provide mechanisms to disable a power source, an auto-on function of the meter, a diagnostic testing function of the meter, or other function of the meter when it has been determined that a triggering event has occurred. The system may further provide mechanisms to reconfigure the meter to perform a new function when it has been determined that the triggering event has occurred.

  • Patent number: 8150115
    Abstract: A chemistry strip reader and method for analyzing chemistry strips. A conveyor moves chemical strips through different imaging positions at discrete points in time across the field of view of a camera, which captures images of each chemistry strip at different discrete times. A processor determines reflectance values for each of the chemical strips from the captured images at the discrete points in time. Calibration targets adjacent the chemistry strips can be used to adjust the determined reflectance values. The light source can sequentially illuminate each chemistry strip with three different wavelengths of light, where the processor calculates a concentration determination associated with the chemistry strip by calculating different chromaticity coordinates for the different wavelengths of light, and comparing them to known chromaticity coordinates for known analyte concentrations.
