Abstract

A plunger having an oblong body with a front end and a rear end and a lancet having a pointed end section projecting axially from said body at the front end is insertable in a cylinder having an oblong hollow body with a front end, a rear end and an axial hole. The plunger of such a length and the lancet is so arranged that the pointed end section of the lancet protrudes a predetermined distance out of the cylinder at the front end when the plunger is inserted thereby defining an operative puncturing position of the medical lancet. The plunger and cylinder have a first engaging stop arranged after partial insertion of the plunger, to temporarily prevent continued insertion at a predetermined initial position. The arresting function of the stop is overcome by applying pressure on the plunger thereby pushing it the remaining distance into the cylinder from the initial position to the operative position.
