Abstract
Needle insertion mechanisms include a housing and a needle holder, the needle holder being linearly guided by the housing to be moved along the needle-axis. A slider linearly guided by the housing and transversally moveable with respect to the needle-axis from a first to a second slider position. The needle holder is operatively coupled to the slider when the slider is in the first position, thereby retaining the needle holder in a retracted position against the bias of a spring acting on the needle holder. In the second position the slider is decoupled from the needle holder and the holder is moved into an inserted position by the spring. A blocking member arranged between the slider and the housing blocking movement of the slider into the second position, is moved by an active drive thereby unblocking the movement of the slider and subsequently moving the slider to the second position.
