Abstract
A needle module for a drive-controlled handheld unit for repeatedly piercing human or animal skin, comprising a housing; a needle holder, which can be moved back and forth in the housing in a longitudinal direction of the housing; a piercing device on the needle holder, which can be moved, on account of the movement of the needle holder, between a proximal and a distal position, in which a piercing tip of the piercing device is arranged outside the housing; a coupling component, which is coupled to the needle holder in such a way that a driving movement provided with a repetition frequency by a drive device that can be coupled to the coupling component can be introduced onto the needle holder; and a damping component, which is arranged between the needle holder and the coupling component and is configured to damp a transfer of force therebetween.
