ABSTRACT:
A hypodermic syringe consists of a syringe body (3) and a cylindrical ampoule (4) inserted therein, a Luer-Lock connection for a cannula (1) being provided on the syringe body (3), the Luer-Lock connection being constructed in two pieces, the connecting member (10) being fixed to the cylindrical ampoule (4) and the threaded sleeve (8) being fixed to the syringe body (3), the connecting member (10) having an axial connecting passage (13) to the interior of the cylindrical ampoule (4), which can be sealed by a removable sealing plug (7), and the cylindrical ampoule (4) being positionally fixed at one end with a conical surface (14) engaged in a tapered bore (8b) in the sleeve (8), and being secured at the other end against axial displacement in the syringe body (3) by means of a retaining collar (5) which can be removably fixed to the syringe body (3) and which acts through a bearing ring (21) against the end (4b), the improved syringe, as a prefilled disposable syringe, ensuring with easy handling a secure and tight attachment of the cannula to the Luer-Lock connection as a result of the two-piece construction of the Luer-Lock connection and guaranteeing a connection free from perforation and fragmentation.
