Patent ID: 7419638

Claim:
A microfluidic device for analyzing a liquid sample, comprising: a first microfluidic channel having a first end and a second end; a second microfluidic channel having a first end and a second end; a third microfluidic channel having a first end and a second end; a sample inlet, fluidly connected to the first ends of the first, second and third microfluidic channels, for receiving the liquid sample; a hydrating buffer inlet, fluidly connected to the first ends of the first, second and third microfluidic channels, for receiving a hydrating buffer; a bellows pump fluidly connected to the second ends of the first, second and third microfluidic channels; a first dried reagent zone wherein a first reagent is printed, fluidly connected between the hydrating buffer inlet and the first end of the first microfluidic channel; a second dried reagent zone wherein a second reagent is printed, fluidly connected between the hydrating buffer inlet and the first end of the second microfluidic channel; and a third dried reagent zone wherein a third reagent is printed, fluidly connected between the hydrating buffer inlet and the first end of the third microfluidic channel.
