  • Patent number: 10974213
    Abstract: An apparatus for and method of enabling enhanced, selective agitation of liquid containing a solid-phase reagent. The apparatus includes at least one liquid-bearing container, a circular tray, and a motor. The liquid-bearing container(s) includes at least one internal baffle that imparts turbulent agitation to the liquid when flowing from one end of the container to an opposite end. The circular tray is adapted for selective rotation about a vertical axis of rotation. The rotary circular tray assembly includes container-receiving stations that selectively retain a respective liquid-bearing container in an inclined or pitched orientation with respect to a horizontal plane. The motor creates centrifugal force, which causes liquid in the container(s) to travel from the first end of the container to the second end of the container via the internal baffle(s), agitating the liquid and the solid-phase portions of the reagent.

  • Publication number: 20190283030
    Abstract: An environmental control system for use in a clinical analyzer module includes an upper deck environmental subsystem comprising a far field sensor, one or more heaters, one or more spine cooling fans, and one or more in-line fluid heat exchangers. The far field sensor is configured to acquire measurements of ambient temperature in the upper deck environmental subsystem. The heaters are configured to generate hot airflow based on the measurements of ambient temperature from the far field sensor. The spine cooling fans are configured to operate in a manner that mixes the hot airflow from the heaters with cool airflow based on the measurements of ambient temperature from the far field sensor. The in-line fluid heat exchangers are configured to heat fluids used in reactions performed on the clinical analyzer module to a constant temperature.

  • Patent number: 6489169
    Abstract: A method for feeding containers into an analytical instrument whereby a sample handler moves and positions racks, containing sample tubes, into, within and out of the analytical instrument. The sample handler has an in-feed and out-feed that advance sample tube racks using a walking beam mechanism. The racks are seated within the in-feed and are transported onto a cross-feed. The cross-feed moves the racks to a position behind the out-feed where the walking beam mechanism moves the tube racks out of the analytical instrument.

  • Patent number: 6374982
    Abstract: A robotic arm has a pair of gripper fingers designed to grip a variety of containers, including capped and uncapped test tubes as well as containers having unique gripping means. The fingers each have upper and lower projections separated by a groove, the respective projections facing each other when mounted to grippers on the robotic arm. The projections and groove serve to firmly hold the containers as well as self-align the unique gripping means on initially unaligned containers within the fingers as the fingers close around the containers. The fingers have clearance to avoid contact with caps on capped test tubes. Stops are provided at the top of each finger to engage one another and prevent fully closed fingers from deforming. The robotic arm may be transported along a rail mounted above the instrument and a gripper assembly, having a gripper arm, mounted to the robotic arm may be rotated above the instrument to move the container to various locations within the instrument.

  • Patent number: 6347552
    Abstract: A profile of a rack, that may have zero, one, or a plurality of containers may be obtained using an ultrasonic sensor. The sensor emits a plurality of ultrasonic bursts and the rack is transported under the sensor at a slew speed that allows the sensor to detect at least first and second echoes from each of the bursts. Data points, corresponding to each of the first and second echoes, are generated and the data points are captured in a memory device. The data points, generally reflecting the levels of the rack and any containers, are processed to dynamically and non-invasively (i.e., without physically contacting the liquid with a probe) determine information about the container types, whether any container is capped, and, if one or more containers are uncapped, the liquid level in the uncapped containers.

  • Patent number: 6331437
    Abstract: An analytical instrument has a sample handler for inputting racks of containers, including various types and sizes of test tubes, both capped and uncapped, and inserts, into the instrument. The sample handler has an infeed, an outfeed and a cross-feed between the infeed and outfeed. The infeed and outfeed advance the racks of containers using walking beam mechanisms which lift the racks by tabs on the right and left sides of the rack, which are positioned at a substantially identical height. Racks input into the infeed are transferred by the walking beam mechanism to a track on the cross-feed. They are then pushed, by a transport subassembly having a platform with pivotable pusher fingers to cam the rack and to push it in only one direction, from behind the infeed to a fixed position behind the outfeed.
