Patent number: 12360019Abstract: The present invention provides an apparatus for collecting and detecting liquid samples comprising a first chamber and a second chamber. The first chamber is used for collecting liquid samples for initial detection, and the second chamber is used for collecting liquid samples for second confirmatory detection. The first chamber and second chamber of the apparatus are detachable. When a second confirmatory detection is necessary, the second chamber can be separated from the first chamber, and then sent to a detection agency for confirmatory detection. It can avoid the contamination of liquid samples caused by contacting with test strip of a traditional apparatus; thus, it can effectively reduce the space required for storing liquid samples and greatly reduce the risk of leakage of liquid sampled during transportation.Type: GrantFiled: July 25, 2018Date of Patent: July 15, 2025Assignee: Hangzhou Biotest Biotech Co., LTD.Inventors: Shujiang Wu, John Wu, Liang Hong, Yangyu Zhu, Lorraine C. Cogan

Patent number: 6669908Abstract: A device for collecting, testing and transporting a liquid specimen of urine or the like incorporates a cup or container and a cooperating lid which becomes sealed about its upper rim when the lid is mated with the specimen-containing cup. An upwardly open subchamber of defined volume, formed in the bottom wall of the cup, is sealed by engagement with a downwardly extending hollow plug portion of the lid that has a bottom wall containing a central aperture closed by a frangible sheet material seal. When initial testing is to be conducted, an elongated assay cartridge is inserted vertically downward through the hollow plug. The bottom end splits open the frangible seal and enters into the subchamber containing the defined volume of the liquid sample, which becomes totally absorbed by a pair of elongated nitrocellulose strips, along which the liquid moves by capillary action to effect the assay tests.Type: GrantFiled: July 25, 2001Date of Patent: December 30, 2003Assignee: Applied Biotech, Inc.Inventors: Daniel C. Weyker, Alan Fujii, John K. Zeis, Thomas J. Marcello, Veronica Terrazas, Lorraine C. Cogan
