Patent ID: 8882794

Claim:
A lancet device comprising, in combination: a hollow housing defining a cavity and having a proximal end and a distal end; a slider slidable at least partially within the cavity of the hollow housing along a longitudinal axis from an outward position to a pushed position, wherein the slider extends outside of the cavity beyond the proximal end of the hollow housing when in the outward position; a needle holder holding a needle, wherein the needle holder is adapted to be rotatable about and translatable along the longitudinal axis when moved from an initial position to an extended position, wherein the slider is in the outward position when the needle holder is in the initial position, and the needle extends outside of the cavity beyond the proximal end of the hollow housing when the needle holder is in the extended position; a first biasing member positioned within the hollow housing at the distal end, the first biasing member exerting a biasing force against the needle holder toward the proximal end when the slider is moved to the pushed position; a second biasing member positioned within the hollow housing at the proximal end, the second biasing member exerting a biasing force against the needle holder toward the distal end when the needle holder is in the extended position; and wherein sliding of the slider from the outward position to the pushed position urges the needle holder to the extended position, and wherein the slider has at least one external surface groove and the second biasing member is positioned in the groove.
