Patent ID: 8802028

Claim:
A disk-based fluid collection device, comprising: a microfluidic disk, which has a geometric center, a top surface, and an outflow boundary; a flow channel pattern, which is formed in the microfluidic disk, the flow channel pattern comprising at least one air vent, at least one conduction channel, which extends to the outflow boundary of the microfluidic disk to form an orifice, and at least one sample storage reservoir, which is formed in the microfluidic disk to store a selected fluid sample, the sample storage reservoir is in fluid communication with at least one air vent, the sample storage being in communication with a sample processing reservoir through a communication channel; and a fluid connection device, which comprises a collection tube having an open fluid receiving end, the collection tube being positioned at the outflow boundary of the microfluidic disk with the fluid receiving of the collection tube opposing the orifice of the flow channel pattern; whereby when the microfluidic disk is set into rotation and the air vent is in an open condition, at least a portion of the fluid sample stored in the sample processing reservoir is acted upon by a centrifugal force induced by the rotation of the microfluidic disk to flow through the conduction channel and discharge through the orifice to be received by the fluid receiving of the collection tube and collected in the collection tube.
