摘要：For a plunger for a syringe, particularly an injection syringe, which comprises ahollow body receiving the plunger, comprising a plunger head for fluid dense limiting afluid chamber of the syringe, and a piston rod fixed to the plunger head with an actuationsection, at which the plunger can be actuated for inserting into the hollow body, wherein
the piston rod is formed by several longitudinally extending axial webs that comprise anoutwardly radial extension rfrom the longitudinal axis and lead into a common crossingsection, which receives the longitudinal axis, wherein at least one free activation edge,which radially protrudes the radial extension r, is provided on the piston rod, which wheninserting the plunger, is engageable with a vibration activator of the hollow body suchthat an acoustic signal is emitted, it is intended, that a swinging arm body arrangedbetween two axial webs couples the activation edge with the crossing section such that incase of a vibration activation in an axial direction the swinging arm body comprises a radialswinging arm length rbetween the activation edge and a crossing section of at least 40%of the radial extension r.
