Patent ID: 8524169

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 sample processing reservoir, which stores a fluid sample, and at least one conduction channel, which has an end in communication with the sample processing reservoir and an opposite end extending to the outflow boundary of the microfluidic disk to form an orifice; 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, 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.
