Wicking methods and structures for use in sampling bodily fluids
First Claim
1. A device, comprising:
- an incision forming device configured to form an incision;
an analysis area configured to analyze bodily fluid from the incision;
a sampling device defining a capillary passageway that extends from the analysis area for drawing the bodily fluid via capillary action to the analysis area;
a wicking member extending from the sampling device proximal the capillary passageway to draw the bodily fluid from the incision to the sampling passageway, wherein the wicking member is an elongate member that is hydrophilic to draw the bodily fluid; and
wherein the wicking member includes a folded section configured to fold against the sampling device until deployment.

Abstract
A sampling member defines a passageway including an inlet opening for reception of a bodily fluid therein, and a wicking member having a first portion coupled with the sampling member adjacent to the inlet opening. The wicking member further includes a second portion displaced from the first portion for initially contacting the bodily fluid. In use the sampling member is placed adjacent to an incision site with the second portion of the wicking member positioned to have the bodily fluid first contact the wicking member and thereby draw the fluid from the incision site to the inlet opening. In related embodiments there is provided a sampling system and method which further includes a lancing device to create the incision and optionally expression members to urge the bodily fluid from the incision, preferably in an integrated unit.
