ABSTRACT:
A hypodermic syringe has a tubular body extending along and centered on an axis and having an axially forwardly open front end, a piston rod axially displaceable in the body and having a plunger rod extending rearwardly from the body, and a plug fitted into the front end and forming an axially through-going passage. An elastomeric membrane is provided in the plug traversing and blocking the passage. Furthermore structure fixed to the plug includes a point in the passage spaced axially slightly forward of the membrane so that the membrane can be deformed axially forward to engage and be pierced by the point.
