    摘要: 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.

    摘要: A prefilled medical syringe includes a syringe barrel. A syringe plunger is disposed in the barrel and displaceable by means of a plunger rod. An end plug closes off a cannula side of the syringe barrel. The plug is provided with a through-channel closed off by a membrane. A finger support is disposed at the end of the syringe barrel opposite the end plug and provided with a through-opening for the plunger rod. A thread system cooperates with the plunger rod and the finger support. The thread system includes a thread sleeve detachably connected with the finger support. The thread sleeve is provided with an inner thread that cooperates with an outer thread on the plunger rod.

    摘要: A hypodermic syringe has a hollow body adapted to hold a liquid, an inner cap fitted over an end of the body, and an axially extending needle seated in the inner cap and having an outer point projecting axially outward from the inner cap and an inner point projecting axially inward from the inner cap toward the body. An outer cap fittable over the inner cap and needle is connected to a clamp ring engageable around the inner cap by a frangible web. Interengaging formations on the ring and on the inner cap releasably retain the outer cap in an outer position spaced axially outward of the body and in which an interior of the outer cap is open to the exterior and an inner position spaced axially closely to the body and in which the interior of the outer cap is not open to the exterior.
