초록 ▼

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.

A hypodermic syringe comprising: (i) a tubular syringe body having a first open longitudinal end and a second open longitudinal end, said body having adjacent its first longitudinal end a transverse wall with a conical bore, said body having an internal thread between said transverse wall and said first open end, (ii) a cylindrical ampoule disposed in said syringe body and having a first longitudinal end and a second longitudinal end, said ampoule having a piston slidable within it, (iii) a connecting means projecting axially at said first end of the ampoule and having a first conical surface and a coaxial second conical surface of lesser cross-section than said first conical surface extending from the end of said first conical surface, said connecting means including a passage through it, said connecting means having its first conical surface seated into said conical bore of said syringe body, (iv) a retaining member axially adjustable on said second open end of the syringe body and including presser means bearing against the second end of the ampoule such that the ampoule is firmly held, against longitudinal movement relative to the syringe body, between said transverse wall and said retaining member, and (v) a coupling member carrying a cannula, said coupling member having an internal chamber communicating with said cannula, said internal chamber being bounded by an internal conical surface engaged over said second conical surface of the connecting means, said coupling member extending into said syringe body at the first longitudinal open end thereof and coacting with said internal thread, such that by rotation of said coupling member with respect to said syringe body the internal conical surface of the coupling member may be firmly engaged in fluidtight manner on the second conical surface of the connecting means.
