    • An infusion apparatus (1) for the administration of a medication from a reservoir (2) with a plug (4) moveable along a central axis in a distal direction for ejection, the apparatus comprising; a housing (5) and a drive mechanism and a force sensor (85) and a transfer element (56); wherein the drive mechanism comprises a first (51) and a second (52) conveying element, the second conveying element (52) to advance the plug (4) in the reservoir (2) in said distal direction, the first conveying element (51) limited for axial movement relative to the housing but rotatable in both senses to facilitate an ejecting or resetting movement of the second conveying element (52); wherein the force sensor (85) is arranged in the central axis between a part of the housing and the proximal end of the drive mechanism and wherein the transfer element (56) is axially stacked between the force sensor (85) and the first conveying element (51) such that the force sensor (85) bears axial forces exerted by the ejection movement; characterized in that the second conveying element (52) moves the transfer element away from the first conveying element (51) against the bias of a restoring force such that the force sensor (85) bears axial forces exerted by the resetting movement.
    • 一种用于从具有插头(4)的储存器(2)施用药物的输注装置(1),所述塞子沿着中心轴线沿远端方向移动以便喷射,所述装置包括: 壳体(5)和驱动机构和力传感器(85)和传递元件(56); 其中所述驱动机构包括第一输送元件(51)和第二输送元件(52),所述第二输送元件(52)沿所述远端方向将所述塞子(4)推进到所述储存器(2)中,所述第一输送元件 )限制用于相对于壳体的轴向移动,但是可以以两种方式旋转,以便于第二输送元件(52)的弹出或复位运动。 其中所述力传感器(85)布置在所述壳体的一部分和所述驱动机构的近端之间的中心轴线处,并且其中所述传递元件(56)轴向地堆叠在所述力传感器(85)和所述第一输送元件 (51),使得力传感器(85)承受由喷射运动施加的轴向力; 其特征在于,所述第二输送元件(52)克服所述恢复力的偏压使所述传递元件远离所述第一输送元件(51)移动,使得所述力传感器(85)承受由所述复位运动施加的轴向力。
