Abstract:
An injector for delivering a fluid medicament to a patient which comprises:a base member having a surface; a skirt having a rim, said skirt extending outwardly from said surface to position said rim thereof at a distance from said surface, said skirt and said surface of said base member defining a compartment therebetween; an injection tube having a tip extending outwardly from said surface and through said compartment for injecting the fluid medicament into the patient; an abutment projecting from said surface of said base member and into said compartment between said skirt and said injection tube; and a suction means in fluid communication with said compartment through said surface of said base member for creating a partial vacuum in said compartment when said rim of said skirt is held against the patient, said suction means drawing skin into contact with said abutment to urge said tip of said injection tube against the skin of the patient to establish an interface seal therebetween, and to stabilize skin adjacent said tip, against said tip, to minimize movement of skin relative to said tip during an injection of fluid medicament.
