Syringe with snap-in enteral connection feature

A syringe comprising:

• a syringe barrel having a distal end, an open proximal end, and a sidewall extending between the distal end to the open proximal end;
• the sidewall defining a chamber, an outer circumferential surface and a snap-in, syringe engagement feature radially projecting from the outer circumferential surface adjacent the distal end thereof;
• a non-luer tip oriented on the distal end of the syringe barrel, dimensioned such that the non-luer tip is not connectable to an intravenous device, the non-luer tip defining a fluid pathway in fluid communication with the chamber;
• an enteral collar, defining a bore in communication with a distal end and a proximal end thereof, threads formed in the bore on the distal end thereof, for engaging a threaded, non-luer connector, the bore having a snap-in, enteral collar engagement feature oriented at the proximal end of the enteral collar that is complementary to and engageable with the syringe engagement feature, the enteral collar engagement feature axially separated from the threads;
• a concave recess formed on one of the engagement features and a complementary mating convex projection on the other of the engagement features;
• the enteral collar engagement feature selectively biased initially in a direction away from a centerline of the bore upon initial axial insertion and advancement of the tip of the syringe into the bore and then biased in a direction toward the bore centerline upon snap-in engagement with the syringe engagement feature;
• and
• the enteral collar surrounding the non-luer tip when the syringe engagement feature is engaged with the enteral collar engagement feature, and the enteral collar being sized to permit connection to an enteral device and prevent connection to a device having a luer connector.

A syringe comprising:

• a barrel having a distal end, an open proximal end, and a sidewall extending between the distal end to the open proximal end;
• the sidewall defining a chamber, an outer circumferential surface, and a plurality of snap-in, syringe engagement features oriented about and radially projecting from the outer circumferential surface adjacent the distal end thereof, each syringe engagement feature defining a recess;
• a non-luer tip oriented on the distal end of the syringe barrel, dimensioned such that the non-luer tip is not connectable to an intravenous device, the non-luer tip defining a fluid pathway in fluid communication with the chamber;
• an enteral collar, defining a bore in communication with a distal end and a proximal end thereof, threads formed in the bore on the distal end thereof, for engaging a threaded, non-luer connector, the bore having a snap-in, enteral collar engagement feature, for engagement with a corresponding syringe engagement feature, the enteral collar engagement feature axially separated from the threads and oriented at the proximal end of the enteral collar;
• the enteral collar engagement feature formed as a discontinuous-annular snap joint, including a plurality of cantilever snap joints, each cantilever snap joint including a cantilever arm, a proximal end of the arm coupled to the bore of the enteral collar and a hook coupled to a distal end of the arm, the hook projecting toward a centerline of the bore, for snap-in engagement with the recess of its corresponding syringe engagement feature;
• and
• the enteral collar surrounding the non-luer tip when the syringe engagement feature is engaged with the enteral collar engagement feature, and the enteral collar being sized to permit connection to an enteral device and prevent connection to a device having a luer connector.
