Abstract

An assembly for use with a syringe having a barrel and a needle includes a sealing element surrounding and positioned over at least a portion of the distal end of the syringe. An adapter at least partially surrounds the sealing element and is positioned over the distal end of the syringe. The adapter has a first skin contacting surface positioned at a distal end thereof. At least a portion of the first skin contacting surface extends generally parallel to at least a terminal end of the needle. The adapter also has a second skin contacting surface positioned proximally relative to the terminal end of the needle and at an angle to the first skin contacting surface. A needle shield at least partially surrounds and is removably positioned over at least one of the adapter, the sealing element and the syringe barrel.

Claims

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; and

a 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.

2. The assembly of claim 1, further comprising:

a first seal formed between the needle shield and one of the adapter, the sealing element, and the syringe barrel;

a second seal formed between the needle shield and the terminal end of the needle; and

at least a third seal formed between the sealing element and one of the syringe and the adapter.

3. The assembly of claim 2, wherein the adapter, the sealing element, and the needle shield are provided in an assembled state as a sub-assembly for assembly with the syringe.

4. A combination of a syringe and an assembly for delivering a medicament into a dermal layer of a patient'"'"'s skin at an injection site, the combination comprising:

the syringe including a barrel and a needle extending from a distal end thereof;

the assembly including;

a tubular-shaped adapter positioned over at least a portion of the distal end of the syringe, the adapter including;

a first su face of the adaptor 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; and

a second surface of the adaptor configured to contact a second area of the patient'"'"'s skin, the second surface being different than the first surface, positioned proximally relative to the terminal end of the needle and lying entirely in a second plane at a predetermined angle relative to the first plane;

a needle shield at least partially surrounding and removably positioned over a least one of the adapter and the syringe barrel; and

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 cylindrically-shaped interior surface of the adapter in contact with and surrounding the outer surface of the sealing element,

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 adaptor 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 adaptor and the second surface of the adaptor are in contact with the first area and second area, respectively, of the patient'"'"'s skin at the injection site du ing delivery of the medicament into the derma layer.

5. The combination of claim 4, further comprising:

a first seal formed between the needle shield and one of the adapter, the sealing element and the syringe barrel;

a second seal formed between the needle shield and the terminal end of the needle; and

at least a third seal formed between the sealing element and the syringe.
