Abstract
The present invention relates to a A device for puncturing an object, in particular a bodily vein, comprising: a body defining an inner cavity with at least one opening and a perforating needle extending in the cavity and being movable in the cavity between a resting position and an active position where the needle extends at least partially through the opening outside the cavity, and actuating means arranged to move the needle between the resting and active positions. The actuating means comprises a tuneable multistable driving mechanism comprising at least a multistable element having a determined switching load, the multistable element being fixedly arranged between the needle and an inner wall of the cavity, and an actuator for transmitting energy to move the needle between the resting and active positions when the energy reaches the switching load.
