Patent number: 8506901Abstract: A biological material test strip and adjacently-located reference color chart are affixed to a lid portion of an all-in-one specimen cup to perform color-based reaction testing of collected biological specimens in an uncalibrated environment. After specimen collection, the lid portion is secured to a container portion of the specimen cup. The cup may then be rotated into an upside down position causing the specimen, under the force of gravity, to pass from the container portion and into a volume of the lid portion, such that the test strip is exposed to the specimen as it is received into the volume of the lid portion. An image of the exposed test strip and adjacently-located reference color chart may then be captured and processed to identify any color matches between the individual test pads on the test strip and the corresponding sequences of reference color blocks on the reference chart.Type: GrantFiled: November 3, 2011Date of Patent: August 13, 2013Assignee: Teco DiagnosticsInventors: Stephen L Chen, KC Chen, Neeraj Kapoor

Patent number: 8501096Abstract: An apparatus and method for the automated preparation of treated monolayers of sample material, comprising: a centrifuge having a rotor (12) carrying removable chamber blocks (14); sample and reagent dispensers (26) and control systems (20). First, centrifugal force sediments sample material discretely to form a monolayer onto a receiving surface member (32) on one of the chamber blocks (14), while the same centrifugal force opens a valve (48) in the chamber block (14) to drain sample material. Then, centrifugal force delivers sequentially into discrete chamber blocks (14) discrete treating agents, during which time the sampler material monolayer is held in place on the receiving surface member (32) by centrifugal force. Then, each chamber block (14) is drained centrifugally through its already opened valve (48). Each treated sampler material is confined to an individual chamber block (14). Batch and random access delivery of treating agents can be employed.Type: GrantFiled: April 14, 2003Date of Patent: August 6, 2013Inventor: Robert Cary Leif

Patent number: 8273312Abstract: A liquid testing assembly for testing a liquid, the assembly comprising a test vessel and a stopper adapted to fit into a free end of the vessel. The stopper substantially hermetically seals the test vessel from the ambient. Further, the assembly includes a support coated with one or more identifying materials for identifying one or more constituents of the liquid. The support is fixed in the stopper and/or the vessel and extends into its interior for a predetermined distance. The liquid testing assembly when assembled is pre-evacuated to a predetermined vacuum sufficient to draw a predetermined volume of liquid to be sampled into the test vessel. The predetermined volume is of such an amount that it wets the one or more identifying materials ensuring identification of one or more constituents present in the liquid. A kit employing the liquid testing assembly is also discussed.Type: GrantFiled: January 22, 2008Date of Patent: September 25, 2012Assignee: Association for Public HealthInventors: Gadi Porat, Joel Stern, Boaz Rimon, Yoram Cohen
