发明名称 Front loading medical injector and syringe for use therewith
摘要 A front-loading syringe which comprises a movable plunger for injecting liquid contrast media, is rotatably mountable on a front wall of an injector housing with an interference fit and in sealed relationship with respect thereto, with or without a pressure jacket, by a first-quick release mechanism. At the same time, the plunger is connected to an injector drive mechanism by a second readily releasable mechanism. During the mounting operation, a sensor reads injection information from an indicator device on the syringe and feeds it to an injector control. An audible-and-tactile indicating mechanism also is activated when the syringe is essentially in the desired mounted position. The syringe may include reinforcing ribs which also function as volumetric gradations, and liquid media presence-or-absence indicating dots which appear circular against a liquid media background and oval-shaped against an air background. An injection end of the syringe comprises an injector portion of reduced diameter inside a screw-threaded attachment portion of larger diameter, and may include loop-shaped reinforcing handle portions.
