  • Patent number: 7540294
    Abstract: A method for cleansing used reaction cuvettes so that whenever certain assays are to be or have been performed in the reaction cuvette, the cuvette is automatically subjected to an additional cleaning operation by providing a number of washing and drying manifolds, each of which is independently selectively activated to perform or not perform a cleaning operation.
    Type: Grant
    Filed: October 17, 2007
    Date of Patent: June 2, 2009
    Assignee: Siemens Healthcare Diagnostics Inc.
    Inventors: Ching-Cherng Lee, Donald Richard Phillips, Sr., Arnold Lloyd Lewis, William Jackson Devlin, Sr.

  • Patent number: 7138091
    Abstract: A reaction cuvette having anti-wicking wall fillets that inhibit liquid wicking along an interior wall surface so that the reaction cuvette may be used in a cuvette-rewashing system in an automated analyzer and not be adversely affected by any reagent contaminants remaining from assays previously performed in said reaction cuvette. The anti-wicking wall fillets comprise a curvilinear taper extending from an open top downwards into the cuvette to form a rounded concave blend between the cuvette's front and back walls and side walls.

  • Patent number: 6118541
    Abstract: Confirming sufficient mixture uniformity between a reagent and liquid sample experiencing a kinetic reaction by comparing the amount of light absorbed within the mixture after the reaction begins with the amount of light absorbed within the solution at the completion of the reaction and requiring that the difference between measured amounts of absorbed light be less than a predetermined value.

  • Patent number: 5827744
    Abstract: A method for cleaning a liquid sample probe in which the probe is positioned within a washing chamber inside a wash body and a purging liquid solution is pumped through the probe into the chamber. A cleaning liquid solution may also be pumped into the chamber around the probe. Either or both liquids are subsequently vacuumed from the chamber drawing air through an annular gap between the probe and the wash body thereby creating a cleaning air flow between the exterior probe surface and the wash body. The cleaning air flow removes all cleaning liquid solution and/or purging liquid solution as the probe is removed from the wash body.
