Abstract
A lancet for use with a lancing device, the lancet including a lancet body and a lancet needle. The lancet needle has a tip for piercing a subject's skin, and the tip of the lancet needle is retractable into the lancet body after use to prevent user contact with the now-contaminated tip. The needle retraction may be effected by a retraction mechanism including a control member with a cam surface and a ram surface and a lever with a cam follower and a needle engagement or stop member. As the control member is moved relative to the lancet, the cam follower transcribes the cam surface, which causes the engagement or stop member to retract the lancet.
