Abstract
A lancing device with automatic stick and lance return features is disclosed. A drive mechanism within the unit comprises a slider-crank linkage combination. It is biased by a spring member to cause automatic firing once a crank member advanced by a user causes movement of an internal linkage member beyond its fully-cocked position. After firing, the lance is withdrawn so as not to pose a threat of secondary injury to the user. In use, the device is substantially silent though its course of operation. Yet, its configuration lends itself to producing a very quick, virtually painless stick with minimal recoil or shock to the device.
