摘要 |
<p>A bipartite injector device (1 sec ) having parts which can be simply assembled utilizing a snap fit arrangement, allowing for low cost production and assembly of parts which can be accurately aligned and connected in a fluid tight manner. The injector device includes a hollow outer shell (2 sec ) having a front closed end (3 sec ) with a hub (5 sec ) extending through the closed end (3 sec ) to a forward position exterior of the shell and terminating in a nozzle (7 sec ). A bore extends through the hub (5 sec ) and nozzle (7 sec ). A cylindrical inner sleeve (20 sec ) is mounted within the hollow shell (2 sec ) in a cantilever manner by means of snap fit locking. The inner sleeve (20 sec ) is formed with a rearward facing tubular spike (55) and a flow passage (27 sec ) extends through the spike (55) such that the flow passage is connected in a fluid tight manner to the bore in the hub (5 sec ) and nozzle (7 sec ) when the inner sleeve (20 sec ) is mounted in the outer shell (2 sec ). The injector device is adapted to receive a cylindrical medicament vial (40 sec ) in the rear open end (4 sec ) of the outer shell (2 sec ). The vial (40 sec ) has an open end (41 sec ) closed by a penetrable stopper (42 sec ) which may be penetrated by the spike (55) in the inner sleeve (20 sec ) to allow fluid tight flow between the vial (40 sec ) and the nozzle (7 sec ). The nozzle (7 sec ) may be connected to a separate charging, mixing or dispensing device (51) by a means of a luer connection (9 sec ,67).</p> |
