Abstract:
1. A device for expressing blood from dermal tissue after lancing, the device consisting of: (a) a support member, and (b) a plurality of movable fingers spaced apart from one another by a narrow slot, each movable finger comprising a vertical component and a radial component and a pivot therebetween, wherein each narrow slot between adjacent fingers has a same width along an entire length of the narrow slot; wherein the support member is in the form of an annular band which includes a top surface, a bottom surface, an inner surface, and an outer surface; wherein the vertical component of each moveable finger has an inner surface and an essentially planar outwardly oriented surface, both surfaces extending from the bottom surface parallel each other, the vertical component having a first edge attached to the bottom surface of the support member and a second edge distal to the first edge; wherein the radial component defines an essentially planar outwardly oriented surface having a first edge and a free end, the radial component extending at an acute angle from the second edge of the vertical component to form the pivot between the second edge of the vertical component and the first edge of the radial component, wherein the free ends of the radial components of the plurality of movable fingers form an acute angle with a common planar surface and at least partially define a generally circular opening; and wherein the free ends of the radial components of the plurality of movable fingers together are configured and arranged to constrict the size of the generally circular opening with uniform force when the free ends and at least a portion proximal the free ends of the essentially planar outwardly oriented surface of the radial components of the plurality of movable fingers are configured to be pressed against the dermal tissue and rotated about the pivot with said force adequate to express blood from said dermal tissue without need to urge said support directly against said dermal tissue.
