  • Patent number: 9011770
    Abstract: The present invention provides a device for detecting the presence of an analyte in a liquid sample. The device has an opening for introducing the liquid sample into a first chamber for collecting the liquid sample, and a second chamber connected to the first chamber by a passageway and containing a test element. The device also has a third chamber connected to the second chamber by a channel and containing a movable member having first and second positions. The third chamber is divided by the movable member into first and second zones, and the first zone has a vent hole. The movable member is in contact with at least one wall of the third chamber to prevent gas communication between the first and second zones.

  • Patent number: 8323583
    Abstract: 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.

  • Publication number: 20090308185
    Abstract: The present invention provides a device (100) for detecting the presence of an analyte in a liquid sample. The device (100) has an opening (115) for introducing the liquid sample into a first chamber (301) for collecting the liquid sample, and a second chamber (601) connected to the first chamber (301) by a passageway (205) and containing a test element. The device also has a third chamber (701) connected to the second chamber (601) by a channel and containing a movable member (311) having first and second positions. The third chamber (701) is divided by the movable member (311) into first (901) and second (902) zones, and the first zone (901) has a vent hole (165). The movable member (311) is in contact with at least one wall of the third chamber (701) to prevent gas communication between the first and second zones (901, 902).
