Abstract:
1. A device for detecting the presence of an analyte in a liquid sample, comprising: an opening for introducing the liquid sample into a first chamber for collecting the liquid sample; a second chamber connected to the first chamber by a first passageway and containing a test element; a third chamber connected to the second chamber by a second passageway and containing a plunger, the plunger comprising a push bar and having first and second positions, the third chamber being divided by the plunger into first and second zones; the plunger in contact with at least one wall of the third chamber to prevent gas communication between the first and second zones; and a lid for closing the opening, wherein the lid contacts the push bar and moves the plunger from the first position to the second position when the opening is sealed with the lid, wherein movement of the plunger from the first position to the second position causes a volume of air to be drawn from the second chamber into the second zone of the third chamber via the second passageway, thereby causing a volume of the liquid sample to be drawn from the first chamber through the first passageway into the second chamber to contact the test element, wherein the first zone of the third chamber is fluidly sealed from the second chamber in the second position of the plunger, and wherein the device is fluidly sealed when the opening is sealed with the lid.
