    • The invention relates to a microsampler puncturing system for collecting a body fluid from a body part, comprising a sample collection unit having a piercing element, and a puncturing instrument having a drive, by which a sample collection unit is movable on a movement path for piercing the piercing element into the skin of the body part and withdraw it again by means of a piercing and retraction movement, a setting device for setting the puncturing depth of the piercing wound to be generated, and a control device for controlling the piercing and retraction movement having the following sequentially executed movement phases: a forward phase (V), in which the piercing element is pierced up to a defined puncturing depth (dm), a retraction phase (R1), in which the piercing element is partially retracted by a retraction distance (Δd) and is decelerated toward the end of the retraction phase (R1), so that it remains projecting into the skin at a defined residual puncturing depth (dr), and a collecting phase (S), in which the piercing element projects into the skin and a body fluid sample is absorbed by the sample collection unit. The setting device is adapted for the defined puncturing depth is settable independently of the chronological mean of the defined residual puncturing depth (dr), with reference to the collecting phase.
    • 本发明涉及一种用于从身体部分收集体液的微量取样器穿刺系统,包括具有穿刺元件的样本收集单元和具有驱动器的穿刺器械,通过该穿刺器具,样本收集单元可在用于穿刺的移动路径上移动 刺穿元件进入身体部分的皮肤并通过穿刺和缩回运动再次撤回,用于设定要产生穿刺伤口的穿刺深度的设置装置,以及用于控制穿刺和缩回运动的控制装置 具有以下顺序执行的移动阶段:穿刺元件被刺穿到限定的穿刺深度(dm)的正向相(V),其中穿刺元件被部分地缩回的收回相位(R 1) 缩回距离(Deltad)并且朝向收缩阶段(R 1)的端部减速,使得其以限定的残余穿刺深度(dr)保持突出到皮肤中 )和收集阶段(S),其中穿刺元件伸入皮肤并且体液样品被样品收集单元吸收。 该设定装置适用于所设定的穿刺深度,可以独立于规定的残留穿刺深度(dr)的时间平均值参照收集阶段进行设定。
