Abstract

A retractable lancet assembly includes a housing and a sharp-pointed lancet movably mounted inside the housing. A movable sleeve is adapted to urge the lancet point in a direction outwardly from the housing. This sleeve and surfaces on the housing contribute to automatically retracting the lancet point inwardly of the housing responsive to movement of the sleeve in the same direction that the sleeve urges the lancet point outwardly.
