A lancet unit has a finger plate (1) with an opening (10) and a stiletto (4) with a pointed front end and a rear end (5) upon which an impact may be imparted to make the pointed end shoot out through the opening (10) in the finger plate (1). The stiletto (4) is suspended behind the finger plate (1) in a meandering leaf spring (14, 15, 16) guiding its displacement perpendicularly to the finger plate (1). A tool for operation of the lancet unit is shaped as a pencil and may be loaded by twisting its front end carrying the lancet unit in relation to the rest of the housing (21). A multifunction button (22), which may be pressed or rotated, will when pressed trigger an impact on the stiletto when the tool is loaded; or eject the lancet unit when the tool is unloaded, and will when rotated define the pricking depth of the stiletto. The double press button function is obtained by centering a hammer (30) in the housing (21) when the tool is loaded, which hammer in the unloaded status is oblique in relation to the axis of the housing (21). |
