Abstract: Described is a pipet, or micropipet, that can be used to dispense multiple aliquots of a biological fluid sample. The pipet includes a capillary tube, a plunger and a plunger stop mechanism having multiple stop positions that allow the plunger to move through the capillary tube in equal incremental steps. The plunger stop mechanism enables the pipet to dispense equal volume portions of fluid in the capillary tube. Advantageously, the pipet can be fabricated at low cost and may be provided as a single-use disposable device. The micropipet may be provided to users with a sample collection device such as a dried blood spot card having multiple collection regions. The pipet optionally includes a dispensing stage that maintains a predetermined separation between the tip of the pipet and a surface of a sample collection medium to limit wicking of the fluid when an aliquot is dispensed.

Abstract translation: 描述了可以用于分配生物流体样品的多个等分试样的移液管或微量捕集器。 移液管包括毛细管，柱塞和具有多个停止位置的柱塞止动机构，其允许柱塞以相等的递增步骤移动穿过毛细管。 柱塞停止机构使得移液管能够分配毛细管中等体积的流体部分。 有利地，移液管可以以低成本制造并且可以被提供为一次性一次性装置。 微量吸管可以提供给具有样品收集装置的用户，例如具有多个收集区域的干血斑。 移液管可选地包括分配阶段，其在移液管的尖端和样品收集介质的表面之间保持预定的间隔，以在分配等分试样时限制流体的芯吸。

Abstract: Provided are devices and methods for sample collection and processing. A tubular body has a chamber closed at a first end by a thin penetrable barrier and open at a second end opposite the first end. The tubular body further includes a partition that divides the chamber into two adjacent compartments, wherein a first compartment of the two adjacent compartments has the partition facing opposite the open end of the chamber and a second compartment of the two adjacent compartments has the partition facing opposite the closed end of the chamber. The partition has one or more holes to allow passage of fluid from the first compartment into the second compartment. A tracking identification may be permanently affixed to the first end of the tubular body.
