1. An assembly for use with a syringe having a barrel and a needle extending from a distal end thereof for delivering a medicament into a dermal layer of a patient's skin at an injection site, the assembly comprising:
a sealing element surrounding and positioned over at least a portion of the distal end of the syringe, the sealing element having a cylindrically-shaped outer surface; a tubular-shaped adapter positioned over the distal end of the syringe, the adapter including:
a cylindrically-shaped interior surface in contact with and surrounding the outer surface of the sealing element;a first surface of the adapter configured to contact a first area of the patient's skin, positioned at a distal end of the adapter and lying entirely in a first plane generally parallel to a longitudinal axis of the needle; anda second, surface of the adapter configured to contact a second area of the patient's skin, the second surface being different than the first surface, spaced from the needle and lying entirely in a second plane at a predetermined angle relative to the first plane; and a needle shield at least partially surrounding and removably positioned over at least of the adapter, the sealing element, and the syringe barrel, wherein the adapter is fixedly and permanently attached to the distal end of the barrel of the syringe and longitudinal movement of the needle is fixed relative to the first surface of the adapter during orientation of the needle relative to the injection site, insertion of the needle in the patient's skin at the injection site and injection of the medicament, wherein longitudinal movement of the sealing element is fixed relative to the adapter, and wherein the first surface of the adapter and the second surface of the adapter contact with the first area and second area, respectively, of the patient's skin at the injection site during delivery of the medicament into the dermal layer. |
