摘要: The invention relates to a drive mechanism (9) for needle insertion arrangement (1), the being arranged as bistable with at least one pivoted link (10, 11) having two stable end positions (LEP, UEP) and an instable transitional central position (CP), further comprising spring (12) biasing out of wherein trigger unit (17, 21) is moving towards beyond (CP) against bias (12).
