A lancing device is used with a lancet for lancing body tissue to result in a wound for bleeding. The lancing device has a cantilevered priming arm having a first arm portion that is generally parallel to an internal channel of the device and a second arm portion that is generally perpendicular to the internal channel. The second arm portion is connected to a lancet carrier and movement of the first arm portion toward the internal channel draws the lancet carrier to a primed position and stores energy in a lancet driver.

Lancing device

A lancet cartridge has a U-shaped support with a pair of anchor portions, a base portion, and a pair of deformable leg portions connecting the anchor portions to the base portion. The pair of deformable leg portions change shape from an initial shape to an extended shape in response to an external applied force and recover to a retracted shape upon removal of the force. The lancet cartridge also has a lancet having a tip end, an opposing base end, and an axis extending between the tip end and the base end. A portion of the lancet is disposed between the pair of deformable leg portions of the U-shaped support. The lancet is movable between a starting position, an extended puncturing position, and an ending position along the axis of the lancet in a path defined by the U-shaped support. When the lancet is in the starting position, the tip end of the lancet is disposed at least partially through the base portion of the U-shaped support, and the U-shaped support is in the initial shape. When the lancet is in the extended puncturing position, the tip end of the lancet is extended through the base of the U-shaped support, and the U-shaped support is in the extended shape. When the U-shaped support recovers to its retracted shape upon removal of the force, the lancet is retracted to the end position.

Lancet cartridges and lancing devices

A lancing device is used with a lancet for lancing body tissue to result in a wound for bleeding. An improved lancing device has a priming knob having a slanted priming notch rotatably connected to the lancing device about an axis of rotation generally parallel to a central axis of the lancing device and a strike path of a lancet carrier. Rotation, translation, or both rotation and translation of the priming knob allows a user to prime the lancing device.
