Patent number: 8323583Abstract: A detection device and a detection method are disclosed. The detection device comprises a sample inlet (132) that allows liquid samples flowing from a collection chamber (20) to a detection chamber (10), which comprises a through hole (135) that allows gases circulation between the detection chamber and the collection chamber, and a sheath (140) that prevents liquid samples from entering into the detection chamber from the collection chamber via the through hole. The detection chamber contains test reagent strips (120) to detect whether samples contain interested analytes. The detection device further comprises a protrusion (131) that enables the detection device standing tilted in the traverse direction. The detection method comprises collecting liquid samples as the first step, followed by standing the device tilted in its traverse direction through a protrusion support, and detecting whether samples contain the analytes.Type: GrantFiled: January 5, 2010Date of Patent: December 4, 2012Assignee: Alere Switzerland GmbHInventors: Lijian Gou, Haipeng Hu

Publication number: 20110165024Abstract: A device for detecting the presence or amount of an analyte in a fluid sample and method thereof, comprises a sample collector and a receiving cup for receiving and holding the sample collector within the receiving cup. The sample collector contains a compressible absorbent member for collecting the fluid sample, and has a first position and a second, locked position within the receiving cup. The absorbent member is uncompressed in the first position and is compressed in the second, locked position. The sample collector or the receiving cup has at least one test element having reagents for detecting the presence or amount of the analyte in the fluid sample.Type: ApplicationFiled: March 17, 2011Publication date: July 7, 2011Applicant: Alere Switzerland GmbHInventors: Yuzhang Wu, Yun Ling, Jielin Dai

Patent number: 7901949Abstract: The present invention provides an assay kit for detecting an analyte of interest in a sample. The kit comprises a) a reporter species; b) a labelled species having first and second binding regions, wherein the first binding region is capable of binding to the analyte of interest and the second binding region is capable of binding to the reporter species; c) an immobilised species capable of binding to the first binding region of the labelled species; and d) immobilised capture reagent capable of binding to the reporter species. The arrangement is such that the sample is contacted with the labelled species, is then contacted with the immobilised species and is subsequently contacted with the immobilised capture reagent, the reporter species being added prior to exposure of the sample to the immobilised capture reagent. If no analyte is present in the sample, the labelled species becomes bound to the immobilised species and is therefore unable to bind to the immobilised capture reagent.Type: GrantFiled: June 12, 2006Date of Patent: March 8, 2011Assignee: Alere Switzerland GmbHInventor: Balbir Raj

Patent number: 7837939Abstract: The present invention is directed to devices and methods for determining the presence of analyte in a fluid sample. The devices utilize a sample collection well, an expression plate for expressing sample into the sample collection well, a plunger that drives a lance, and a test compartment containing test elements. The devices also preserve an aliquot of fluid sample in a reservoir for later confirmation testing. When the plunger is lowered into the sample collection well, a lance on the device punctures a frangible material that covers a sample outlet. When the sample outlet is thus opened, fluid sample flows from the sample collection cup to the test compartment. In one embodiment the plunger is lowered as a cap is applied to the device. The devices are useful for detecting the presence of analyte in a wide variety of fluid samples, such as saliva, oral fluids, and more. The invention also provides methods of using the devices, and kits containing the devices.Type: GrantFiled: August 20, 2007Date of Patent: November 23, 2010Assignee: Alere Switzerland GmbHInventors: Hsiaoho E. Tung, Yuzhang Wu, Jeilin Dai, Ying Yang

Patent number: 7803636Abstract: The present invention provides devices, methods and kits for detecting the presence of an analyte in a liquid sample. The invention provides devices having a positive control area covered with an opaque, movable material, such as an ink, dye, or other material, that is moved on the device by the flow of liquid sample, thereby exposing the positive control area underneath. Using the interaction of colored signals from the positive control area and the analyte binding area, a recognizable symbol is revealed on the device that correlates with the test results, and appears as the test is conducted.Type: GrantFiled: November 7, 2007Date of Patent: September 28, 2010Assignee: Alere Switzerland GmbHInventors: Fei Gao, Shujiang Wu, Huikang Chen, DengFeng Xiong, Jinn-nan Lin, James McMenamy
