ROTATABLE DISK-SHAPED FLUID SAMPLE COLLECTION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a sample collection device for a fluid.SOLUTION: The sample collection device for a fluid includes: a substantially disk-shaped body having a periphery; a capillary channel which extends through the body, is bounded by the periphery, has a first end and a second end, and has the first end adapted to draw the fluid into the channel by capillary action; a sample collection well which is located in the vicinity of the second end and is in fluid communication with the capillary channel; and an axis of rotation which extends through the center of the disk and is substantially perpendicular to the major surface of the disk-shaped body. In a preferred embodiment, the sample collection device is adapted to rotate about the axis of rotation within a cartridge having a housing including an air vent which is in fluid communication with the capillary channel when the disk is rotated in a first position.
