A lancet injector is provided which has an elongated housing (12), a slidable lancet holder (16) in the housing, a compression spring (34) connected between the holder (16) and one end of the housing (20), and a control member (48) for moving the holder (16). The control member (48) is operable to move the lancet holder (16) to a latched retracted position against the force of the sping, release the holder so that it moves linearly under the force of the spring and inertia to a skin piercing position and then back to a neutral position in which the spring is in a free length condition. |
