Prefillable syringes and injectors for use therewith

A system for injecting a liquid medium, comprising a syringe and an injector, the syringe comprising:

• a main body;
• and
• a releasable mounting mechanism comprising at least two pairs of mounting flanges operably associated with the main body;
• the injector comprising:
• a housing;
• and
• a cooperating retainer disposed housing, the cooperating retainer defining at least four slots therein for receiving therethrough the at least two pairs of mounting flanges on the syringe, the cooperating retainer further comprising at least two pairs of retaining flanges to releasably engage the at least two pairs of mounting flanges when the syringe is mounted within the cooperating retainer, the first pair of retaining flanges being positioned at a first axial location on the retainer and the second pair of retaining flanges being positioned at a second axial location on the retainer, the first and second pairs of retaining flanges being radially offset from one another, whereby the at least four slots and the at least two pairs of retaining flanges on the retainer cooperate with the at least two pairs of mounting flanges associated with the syringe to releasably engage the syringe with the injector.

An injection apparatus comprising, in combination:

• a syringe comprising:
• a main body comprising a rear portion;
• and
• at least two pairs of mounting flanges connected to the rear portion of the main body, the first pair of mounting flanges being positioned at a first axial location on the syringe and the second pair of mounting flanges being positioned at a second axial location on the syringe, the first pair of mounting flanges being radially offset from the second pair of mounting flanges;
• and
• an injector comprising:
• a housing having a front wall;
• and
• a retainer on the front wall including at least four slots for receiving therethrough the at least two pairs of mounting flanges on the syringe, the retainer further comprising at least two pairs of retaining flanges to releasably engage the at least two pairs of mounting flanges when the syringe is mounted within the retainer, the first pair of retaining flanges being positioned at a first axial location on the cooperating retainer to engage the first pair of mounting flanges and the second pair of retaining flanges being positioned at a second axial location on the cooperating retainer to engage the second pair of mounting flanges, the first pair of retaining flanges being radially offset from the second pair of retaining flanges, whereby the at least four slots and the at least two pairs of retaining flanges of the retainer are positioned to receive the at least two pairs of mounting flanges on the syringe when the syringe is releasably mounted on the front wall of the housing.
