Abstract
A disposable lancet assembly is provided, including a housing serving as a lancet-holder guide, a lancet holder body reciprocable in the housing guide, and a flat-bladed lancet mounted in one end of the lancet holder body. Included in the invention are integral strategically positioned abutments which serve dual functions providing snap-action drive for the lancet, together with steps for lancet movement control. The simple coil spring provides damping of the lancet drive in the puncture direction with automatic withdrawal of the lancet into the housing.
