    • The present application relates to methods and devices for providing a reduced risk of free flow from medical devices such as an infusion pump. A medicament containing reservoir (100) is provided with a piston having a sealing portion (121) formed by a material of a first stiffness. The piston further comprises a core member (110) of a material having a stiffness larger than said first stiffness, the core member comprising one or more connective members (111) being adapted to cooperate with said one or more protrusions of the linear actuation member. The one or more connective members being adapted to be substantially rigid in the axial direction while being resilient in a radial direction, thereby forming a releasable snap or friction fit connection with the linear actuation member. Thereby a mechanism is provided which is engageable by a purely axial relative displacement and which is disengageable by retracting the linear actuation member axially relative to the piston by exerting a pulling force greater than a predetermined limit.
    • 本申请涉及用于从诸如输液泵的医疗装置提供自由流动的风险降低的方法和装置。 含有储存器(100)的药物设置有具有由第一刚度的材料形成的密封部分(121)的活塞。 活塞还包括具有大于所述第一刚度的刚度的材料的芯构件(110),所述芯构件包括适于与所述线性致动构件的所述一个或多个突起配合的一个或多个连接构件(111)。 一个或多个连接构件适于在轴向方向上基本上刚性,同时在径向方向上具有弹性,从而形成与线性致动构件的可释放的卡扣或摩擦配合连接。 因此,提供了一种机构,其可以通过纯粹的轴向相对位移接合,并且通过施加大于预定极限的拉力,使线性致动构件相对于活塞轴向缩回。
