Mixing apparatus & method for an optical agglutination assay device |
摘要 |
An assay device for detecting the presence of analytes in an unknown sample includes a reaction system wherein resilient storage reservoirs containing reagents are fluidly connected to a track containing the sample. An actuation mechanism forces the reagent from each of the reservoirs into the track where the reagents mix together and with the sample. The mechanism produces a first flow rate and the mechanism is operable to reverse the pressure applied to the reservoirs to reverse the direction of flow of the fluids in the track for a predetermined period of time after which the flow is again reversed. The mechanism then reduces the force applied to allow a second flow rate less than the first flow rate so that reaction can occur whereby a determination may be made as to whether the target analyte is present in the sample.
