  • Patent number: 9719934
    Abstract: Disclosed is an assay result reading apparatus for use with an assay in which a detectable substance tends to accumulate within a detection zone of the assay, the reading apparatus comprising: a housing or baffle, having a window therein; a light source which emits light through the window so as to illuminate the detection zone of the assay; and a light detector to detect the amount of light reflected and/or transmitted by the detection zone, which amount is at least partly dependent on the amount of detectable substance accumulated in the detection zone; wherein the shape of the window is adapted to render the reading apparatus less sensitive, preferably insensitive, to minor mis-positioning of the detection zone relative to one or more of the window, the light source and the light detector.

  • Patent number: 9327283
    Abstract: A device and a method for analyzing an analyte in a liquid sample are provided. The device comprises a detecting chamber included in a detection device for containing a detecting element; a liquid sample transferring chamber; and a film with small pores disposed between the detecting chamber and liquid sample transferring chamber. When the detection device is inserted into a liquid sample collecting chamber, the liquid sample in the collecting chamber enters the liquid sample transferring chamber but can not enter the detecting chamber via the film with small pores. When a piston is inserted into the liquid sample transferring chamber, the piston forces a part of liquid sample in the liquid sample transferring chamber to enter the detecting chamber via the film with small pores. Using the device and the method can determine an analyte in a sample quantitatively and can complete the detection in one step.

  • Patent number: 9151749
    Abstract: Disclosed is a method for determining the presence and/or amount Oran analyte of interest in a liquid sample comprising the steps of: contacting the liquid sample suspected of containing analyte with a gas generating means (eg. catalase and peracid or peroxygen compound), which gas generating means forms a gas dependent upon the presence, absence or amount of analyte, which gas creates one or more bubbles in the liquid sample which act to alter the flow of liquid along a flow path; and determining an alteration of flow in the liquid wherein the alteration of flow of liquid along the flow path is indicative of the presence and/or amount of analyte in the liquid sample.

  • Patent number: 9052311
    Abstract: Disclosed is an assay device to determine the presence of at least one analyte of interest in a liquid sample, the device comprising means for generating a first signal (the ‘test’ signal) which indicates the presence and/or amount of analyte of interest in the sample; and means for generating a second signal, the generation of which second signal indicates both (a) the test has been successfully conducted, and that (b) sufficient time has elapsed following contact of the assay device with the liquid sample for the test to be read and the first signal to have been properly generated.

  • 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: 8992854
    Abstract: Disclosed is an assay device comprising liquid transport means adapted to take up a liquid sample and conduct the liquid to an analyte detection region operable to provide a test signal indicative of the presence and/or amount of an analyte in the liquid sample; the assay device further comprising a sample presence signal generation means, which is not generated by means of an immunoreaction. This sample presence signal generation means can comprise a colored portion, which is overlaid by a material (e.g. nitrocellulose) that is opaque, when dry, and translucent or transparent, when wet, to allow the colored portion to become visible to the user. In another embodiment the signal generation means comprises a color changing material which under-goes a change in its visible properties upon wetting (e.g. pH indication). A third embodiment uses a mobilizable detectable which, when wetted by the sample, is carried along resulting in a streaked line parallel with the flow direction.

  • Patent number: 8980177
    Abstract: Disclosed is a fluidic assay device for assaying at least one property of a liquid sample, the device comprising: (i) a liquid sample application region; (ii) at least one test flow path in liquid flow communication with the sample application region; (iii) a reference flow path in liquid flow communication with the sample application region; and (iv) a junction region, at which the test flow path and the reference flow path contact one another, the junction region typically comprising an outlet, conduit, chamber or other portion which permits the onward flow of liquid; wherein a liquid flowing along the reference flow path, upon reaching the junction region, has the effect of preventing the flow of liquid along the test flow path. The invention relates to a fluidic device for the passage of a liquid. It also relates to an assay device suitable for measurement of the amount and/or presence of an analyte in, or property of, a fluid sample.
