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, the assembly comprising:

a sealing element surrounding and positioned over at least a portion of the distal end of the syringe;

an adapter at least partially surrounding the sealing element and positioned over the distal end of the syringe, the adapter including;

a first skin contacting surface positioned at a distal end of the adapter, at least a portion of the first skin contacting surface extending generally parallel to at least a terminal end of the needle, and

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; and

a needle shield at least partially surrounding and removably positioned over at least one of the adapter, the sealing element, and the syringe barrel.

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 needle shield is connectable to the adapter, and at least a fourth seal is formed between the adapter and the sealing element.

4. The assembly of claim 2, wherein the sealing element is directly connected to and formed integrally with the needle shield.

5. The assembly of claim 2, wherein the sealing element engages a proximal portion of the needle in a fully assembled operative configuration.

6. The assembly of claim 5, wherein the needle is aligned relative to at least the first skin contacting surface by the sealing element.

7. The assembly of claim 5, wherein the sealing element comprises multiple segments which engage the proximal portion of the needle.

8. The assembly of claim 7, wherein the multiple segments of the sealing element are separated and at least partially spaced-apart in an unstressed state.

9. The assembly of claim 2, wherein the needle shield is directly connectable to the sealing element, and

the adapter includes a cut-out portion sized and shaped to accommodate installation of the needle shield around the needle.

10. The assembly of claim 9, wherein the sealing element engages a proximal portion of the needle in a fully assembled operative configuration.

11. The assembly of claim 2, further comprising a hinged element connected to the adapter which in an operative configuration engages and supports a proximal portion of the needle.

12. The assembly of claim 2, wherein the adapter further comprises a first component connectable to the syringe and a second component slidably connected to the first component.

13. The assembly of claim 12, wherein the terminal end of the needle extends distally beyond a distal end of the second component in a retracted storage position of the second component, and the distal end of the second component extends distally of the terminal end of the needle in an extended operative position of the second component.

14. 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.

15. The assembly of claim 2, wherein the first skin contacting surface is non-linear in a plane perpendicular to a plane defined by a longitudinal axis of the needle to provide sufficient clearance between the first skin contacting surface and the needle to allow effective installation of the needle shield.

16. The assembly of claim 2, wherein the sealing element surrounds an entire circumference of the needle at a point along a longitudinal axis of the needle.

17. A combination of a syringe and an assembly, the combination comprising:

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

the assembly including;

an adapter positioned over at least a portion of the distal end of the syringe, the adapter including;

a first skin contacting surface positioned at a distal end of the adapter, at least a portion of the first skin contacting surface extending generally parallel to at least a terminal end of the needle, and

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; and

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

18. The combination of claim 17, wherein the assembly further comprises a sealing element surrounding and positioned over at least a portion of the distal end of the syringe, and wherein the adapter at least partially surrounds the sealing element.

19. The combination of claim 18, 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.
