Abstract

Drug delivery safety devices comprise a safety needle device comprising a needle hub, a needle cannula, and a safety feature; and a cap comprising a cap body having a proximal end attached to the safety needle device and a distal end having an access opening that is in fluid communication with the needle cannula. The safety needle device allow for an integrated device for both filling and injection that do not interfere with passive safety features. The caps may have a fill feature that engages with a safety feature of the safety needle device to keep it in a fill state.

First claim

What is claimed is:

1. A drug delivery safety device comprising:
a safety needle device comprising a needle hub, a needle cannula, and a safety feature; and
a cap comprising a cap body having a proximal end attached to the safety needle device and a distal end having an access opening that is in fluid communication with the needle cannula, the access opening comprises an access protrusion extending from the distal end of the cap, the cap further comprises a blunt fill cannula extending from a distal end of the access protrusion and in fluid communication with the needle cannula and a seal between the blunt fill cannula and an inside surface of the access protrusion.

2. The drug delivery safety device of claim 1 , wherein the proximal end of the cap is removably attached to the safety needle device.

3. The drug delivery safety device of claim 1 , wherein an inside surface of the cap further comprises a fill feature engagable with the safety needle device for maintaining a fill state of the safety needle device.

4. The drug delivery safety device of claim 3 , wherein the fill feature comprises a rib located on the inside surface of the cap body in contact with the safety feature of the safety needle device.

5. The drug delivery safety device of claim 4 , wherein the safety feature of the safety needle device comprises an activation latch and the rib keeps the activation latch in an inactive state.

6. The drug delivery safety device of claim 3 , wherein the safety feature of the safety needle device comprises a clip and the fill feature keeps the clip open in an inactive state.

7. The drug delivery safety device of claim 1 , wherein the safety feature comprises a guide element of a housing body of the safety needle device.

8. The drug delivery safety device of claim 1 , wherein the cap snap-fits to the safety needle device.

9. The drug delivery safety device of claim 1 , wherein the cap rotatably-fits to the safety needle device.

10. The drug delivery safety device of claim 1 , wherein the cap press-fits to the safety needle device.

11. The drug delivery safety device of claim 1 , wherein the proximal end of the cap is attached to the needle hub of the safety needle device.

12. The drug delivery safety device of claim 1 , wherein the cap further comprises a septum inside the cap body at the distal end adjacent to the access opening and optionally a vent lumen.

13. The drug delivery safety device of claim 1 , wherein the cap further comprises a finger hilt.

14. The drug delivery safety device of claim 1 , wherein the cap further comprises a shoulder at the distal end of the cap body from which the access protrusion extends.

15. The drug delivery safety device of claim 1 further comprising a tip cap that covers a tip of the blunt fill cannula.
