Automated Chemical Analysis Patents (Class 436/43)
  • Patent number: 10809275
    Abstract: Manually operated pipettors, widely used in clinical, forensics, pharmaceutical research, hospital and biotech laboratories to transfer small volumes of liquid, may be subject to positional errors, operator use errors and hidden performance degradation. Manual pipette performance cannot be accepted without monitoring and reporting. This invention concerns a computer controlled vision tracking and lighting system working in conjunction with a sensor controlled fluid dispensing device and controller to confirm pipette tip positional locations during aspiration and dispensing operations with automatic monitoring of liquids entering and leaving a pipette apparatus to digitally track a manual pipetting operation with a digital output file of validated liquid transfer results. The invention may also monitor possible error conditions and prevent improper liquid transfers during the manual process.

  • Patent number: 10803266
    Abstract: An identification device for identifying identifiers on and/or features of laboratory objects and/or of samples located therein in conjunction with automated laboratory systems or facilities, for example, medical, chemical, or pharmaceutical analysis devices. Barcodes on sample containers, for example, sample tubes, reagent tubs, or microplates are used, for example, as identifiers. An optical recording unit and a mirror are used, the spacing is variable for the detection of laboratory objects, each at different distances, from a recording distance by the optical recording unit is within a depth of field of the optical recording unit. The mirror is used for imaging the laboratory object to be detected on the optical axis. The identification device is substantially simplified, more reliable, and more cost-effective in comparison to known devices that use a zoom lens together with an autofocus unit.

  • Patent number: 9656266
    Abstract: A diagnostic system with a handling system that has a loading bay to receive and hold a plurality of carriers. An identification device is configured to identify an identifying feature of the carriers to determine the type of contents loaded on each carrier. A transporter transports the carriers from the loading bay to a first or second location depending on the determined type of contents on each carrier. The transporter has random access to the plurality of carriers in the loading bay. A diagnostic process is conducted using the contents. A carrier, such a for reagents, has one or more holding portions, at least one of which can be moved or rotated with respect to the body of the carrier for mixing or stirring the contents of a container coupled therewith. Also, a retention member can be associated with a positioning device, such as a carousel, to lock and unlock the carrier with respect thereto.

  • Patent number: 9605298
    Abstract: Systems and methods are provided for high speed sorting of objects in a continuous body of fluid. The object can be analyzed within one or more interrogation volumes that allow for simultaneous or time-correlated measurement of the object's properties. A processor can interpret the properties of the object and then measured and then direct the object to one of a plurality of downstream flow paths. In some embodiments, the sorting of the object is based on two or more properties of the object. The sorting process can be repeated to create a network of sorting events.

  • Patent number: 9586204
    Abstract: The present disclosure proposes a design of a biomedical paper sensor which can determine the concentration of biological materials in fluids such as blood, urine, and saliva. The sensor contains a plurality of axially radiating test zones, each test zone separated from other test zones by wax ink barriers formed by a process that produces thin walls. Each test zone can contain a unique test reagent, or a unique concentration of a test reagent, and can also be identified by printed text. The region of the device outside of the test zone area is printed with a uniform reference color. Benefits of the invention include increased accuracy in the measurement of the concentration of biological materials due to the larger test zone area. Benefits also include the integration of the reference or calibration color which simplifies the calibration needed for quantification of the concentration.

  • Patent number: 9297820
    Abstract: An automatic analyzer includes a storage unit for storing operation information information about usage histories of expendable supplies provided for the analysis, and an analysis-ID control unit giving an ID to the analysis, the analysis ID being used as information for identifying the analysis to derive a calibration curve. Data stored in the storage unit is organized along the same time axis both in the order of samples subjected to the analysis and inspection, and in the order of analysis items, so that the data is output in a total data display area. The data is organized from the viewpoint of an analysis process of an analysis item of each sample. By use of information used to identify an influence range based on a kind of an abnormal state, which is stored beforehand, a judgment is made as to whether or not it is necessary to perform reinspection.

  • Patent number: 9256935
    Abstract: A gripping element may be commanded to move to pre-determined robot-frame locations, and markings may be punched into a calibration sample capture substrate at each location. A calibration image may be obtained, and fiducial markings on the gripping element may be detected. A set of calibration regions of interest may be predicted, and the previously punched markings may be detected. A sampling system may then create a mapping transfer function between detected image locations and real-world locations resulting from the commanded locations of the gripping element when the markings were punched. An indication may subsequently be received that a biological sample capture substrate is ready to be processed. An image of the sample capture substrate may be obtained, and the fiducial markings may be detected. Based on those image locations and the mapping transfer function, biological sample portions may be automatically taken from the sample capture substrate.
