Abstract

Medical injection devices incorporate collapsible, passive needle shields for avoiding inadvertent needle tip contact with objects. The needle shield is coupled to the distal end of the syringe barrel, enveloping the needle in its relaxed, non-compressed state. When the needle shield is in a relaxed, non-collapsed state, its contact surface extends distally longer than the needle tip, so that the tip is enveloped and shielded by the contact surface. Abutment of the contact surface against a desired patient body site stabilizes the syringe orientation. Thereafter, the syringe barrel is advanced, which passively collapses the needle shield, so that the now exposed needle tip pierces the patient's body, allowing injection of medical fluids by advancement of the syringe plunger. Injection device embodiments include ocular injection devices for injecting medication through the sclera of a patient's eye.
