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
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.
An injector for injecting a liquid from a syringe, said syringe having a plunger, said injector comprising: a housing having a front wall; readily releasable mounting means on said housing front wall for supporting the syringe for an injection operation, said readily releasable mounting means includ
An injector for injecting a liquid from a syringe, said syringe having a plunger, said injector comprising: a housing having a front wall; readily releasable mounting means on said housing front wall for supporting the syringe for an injection operation, said readily releasable mounting means including retaining means for releasably engaging a retaining portion on the syringe, slot means of said readily releasable mounting means for receiving therethrough the retaining portion on the syringe, inner surface means of said readily releasable mounting means for engaging the retaining portion on the syringe when the syringe is inserted into and rotated in said readily releasable mounting means; drive means in said housing movable through said housing front wall for controlling the movement of the plunger in the syringe; and annular sealing means on the front wall of said housing for engaging annular sealing means on the syringe, for perpendicularly aligning the plunger and the drive means and for minimizing slack between the syringe and the slot means.
