Method for producing a syringe with a glued cannula, in which a syringe body is provided with a lubricant internally at high temperature, and either the lubricant is prevented from penetrating into a cannula receptacle of the syringe body, or the lubricant is cleared from the cannula receptacle of the syringe body afterward, and a cannula is glued into the cannula receptacle; and a syringe with a body comprising a cylinder portion and a narrowed cannula receptacle portion, whereby the cylinder portion is provided internally with a lubricant&#x2014;this being deposited at high temperature&#x2014;a cannula receptacle of the receptacle portion is cleared of lubricant, and a cannula is glued into the cannula receptacle.

Method for manufacturing a hypodermic syringe with glued-in canula and hypodermic syringe

A needleless syringe that provides the necessary high pressure, is easily generated despite the utilization of relatively thin-walled glass ampules for storing an injectable medicine. A plastic body of the needleless syringe contains an interior space surrounded by walls. The interior space is divided into a first region with one end open to the outside and an adjoining second region. A glass ampule containing a medicine, which is sealed at both ends with plunger-type stoppers, is disposed in the first region. The second region contains an output opening leading through the wall of the plastic body. A ram is provided with which the stopper that is averted from the second region can be pushed into the glass ampule and into the second region.
