Abstract
A lancet type device having a movable and retractable lancet tip is disclosed. The lancet tip extends beyond the end of a lancet body. The device includes an actuating mechanism that moves and retracts the sharp distal lancet tip linearly into and out of contact with a patient's skin. The actuating mechanism includes an arm with a substantially 'V' shaped groove. In one embodiment, the arm extends away from and pivots around the proximal end of the device. In another embodiment, the arm moves transversely across the device. A cylindrical cam follower protrudes from the lancet body. Contact between the groove and the cam follower moves the cam follower, and consequently the lancet body, in a linear direction along the axis of the lancet body.
