ABSTRACT:
An adjustable tip for a blood lancet device for causing different depths of skin puncture is provided. An inner sleeve has a partially enclosed distal end which forms a stop for the shoulder of the lancet. An outer sleeve is pressed together with a cylindrical ring to form an internal camming surface, which captures a cam follower carried by the inner sleeve when the outer sleeve and cylindrical ring are slid as a unit on the inner sleeve. Rotation of the outer sleeve causes longitudinal motion between the distal ends of the inner and outer sleeve creating an adjustable double bottom which creates various puncture depths.
