SINGLE PUNCTURE LANCING FIXTURE WITH DEPTH ADJUSTMENT AND CONTROL OF CONTACT FORCE.

摘要

A lancing mechanism fixture for puncturing skin with a lancet having a penetrationend being moveable in a direction substantially parallel to the longitudinalaxis of the lancet, the penetration end being moveable from a first position toa second position during a forward stroke, the penetration end being movablefrom the second position back to the first position during a return stroke. Themotion of the lancet is controlled by a cam mechanism including a slot cam and acam follower connected to a lancet. A drive member applies a linear force to theslot cam whose linear motion and slot path shape forces the lancet to move froma first position to a second position and back to the first position.
