Abstract: An injection syringe with retractable injection needle has a liquid container with a needle opening, as well as a plunger/plunger rod assembly which is moveable over a travel in the liquid container. Furthermore, an injection needle is provided, which in an active position projects out of the liquid container through the needle opening and in a retracted position is located fully within the liquid container. The injection syringe has a travel limiter which is activated after an injection has been administered using the injection syringe and subsequently the injection needle with needle mount has been moved into the retracted position by the plunger/plunger rod assembly being retracted, after which it restricts the plunger/plunger rod assembly in the event of a movement towards the needle opening, in such a manner that the injection needle cannot be forced out of the liquid container.

Abstract: The present invention relates to an injection syringe with retractable needle, at least comprising: a liquid container with an outlet opening; a needle with needle mount which is or can be secured in or on the outlet opening of the liquid container; a blocking means which is designed to block the needle mount in the outlet opening, which blocking means can only be unblocked by the needle mount with needle being retracted into the liquid container.
