  • Patent number: 7943381
    Abstract: A system for automatically testing a fluid specimen, e.g., urine, to indicate the presence of specified chemical components in the specimen. The system preferably utilizes an assaying device comprised of a collection cup and a cap which carries at least one test strip. The device includes an integrated aliquot delivery mechanism actuatable to wet the test strip with an aliquot delivered from the fluid specimen. The assaying device is configured to operate in conjunction with an electronic reader device capable of actuating the aliquot delivery mechanism and reading the reaction of the test strip. A preferred reader device defines a keyed receptacle for accommodating a complementary shaped cup housing in a particular orientation. The reader device is comprised of a camera for capturing the image of a test strip, an actuator for actuating an aliquot delivery mechanism, and a microprocessor/controller for (1) controlling the camera and actuator and (2) processing the image.

  • Patent number: 7919060
    Abstract: A substantially moisture-proof, airtight dispenser for both storing and dispensing several flattened articles such as diagnostic test strips. The inventive dispenser includes a novel pivotable housing that a user need merely grab and squeeze to eject a test strip. Independent movement of the user's fingers to push a button or turn a knob is unnecessary to dispense a strip, which makes the present invention well suited for diabetics suffering from nerve damage in their extremities and other complications resulting from the disease. The invention includes a novel flexible arm member and pusher head that engage and push an article from the dispenser as the two parts of the housing are pivoted together. The articles are dispensed through an exit that is configured with a novel flexible seal that maintains the dispenser substantially airtight. Several inventive seal embodiments and methods of making the same are disclosed.

  • Publication number: 20110059548
    Abstract: The present invention generally discloses an extraction system that provides a locale for fluid processing and extraction on a post-microcapture transfer film. The extraction system includes a transfer film carrier and an extraction device forming a reservoir. The extraction system selectively excludes regions of the transfer film from the reservoir to advantageously reduce contamination due to matter adhered to the transfer film by non-specific transfer.
