ABSTRACT:
A lancet device for puncturing the skin of mammals, especially humans, has a bushing with a grip portion and opposite the grip portion a free end defining a plane. An insert is axially slidably connected within the bushing. The insert has a first and a second end, with the first end having a grip element and the second end having a projecting lancet with a tip for puncturing the skin. The grip element comprises a diaphragm with a preset pressure point, and upon surpassing the pressure point of the diaphragm with an axially directed force in the direction toward the free end of the bushing, the lancet is released with a preset impulse via the insert and penetrates the plane defined by the free end to puncture the skin.
