Drug delivery devices having non-luer connections and adapters and adaption connectors for providing non-luer connections to drug delivery devices are provided. An exemplary drug delivery device for use with a catheter connection includes a blunt needle component with a non-luer connection and a filter component with a non-luer connection, wherein the non-luer connections of the blunt needle component and filter component are incompatible with standard luer fitting and intravenous route-accessing devices. In one or more embodiments, an adapter having a non-luer connection at one end and a luer connector is provided for use with blunt needle components and filter components wherein one of the blunt needle component and the filter component includes a luer connection and the other of the blunt needle component and the filter component includes a non-luer connection. Methods of delivering liquid medication to a catheter are also provided.

1. A drug delivery device comprising: a blunt needle component including an open distal end, an blunt needle having a non-luer shape extending from the open distal end, the blunt needle having a sidewall including an inside surface and an outside surface, a length greater than 0.5 inches and a lumen in fluid communication with the open distal end; anda filter component including an inlet for receiving the blunt needle, a non-luer connector disposed adjacent to the inlet for engaging the blunt needle, an outlet and a filter attached to one or both of the inlet and the outlet in fluid communication with the inlet and the outlet,wherein the blunt needle and the non-luer connector are incompatible with standard luer connectors and intravenous route-accessing devices. 2. The drug delivery device of claim 1, wherein the blunt needle has an outer diameter that prevents attachment of the blunt needle to a standard luer connector. 3. The drug delivery device of claim 1, wherein the blunt needle has a tapered outer cross-sectional width to prevent attachment of the blunt needle to a standard luer connector. 4. The drug delivery device of claim 1, wherein the blunt needle and an inside surface of the non-luer connector of the filter component both have an oval shaped cross-section to form a fluid tight connection. 5. The drug delivery device of claim 1, wherein the blunt needle and an inside surface of the non-luer connector of the filter component both have a triangular shaped cross-section to form a fluid tight connection. 6. The drug delivery device of claim 1, wherein the outside surface of the blunt needle has a tapered cross-section width that increases from the distal open end to a proximal open end of the blunt needle. 7. The drug delivery device of claim 6, wherein the cross-sectional width of the outside surface at the distal open end is from about 0.05 inches to about 0.7 inches. 8. The drug delivery device of claim 7, wherein the cross-sectional width of the outside surface at the proximal open end is from about 0.12 inches to about 0.15 inches. 9. The drug delivery device of claim 1, wherein one or both of the outside surface of the blunt needle and the non-luer connector of the filter component have cross-sectional widths that are smaller than cross-sectional width of standard luer connectors, intravenous route-accessing devices. 10. The drug delivery device of claim 1, wherein one or both of the outside surface of the blunt needle and the non-luer connector of the filter component have cross-sectional widths that are larger than cross-sectional widths of standard luer connectors and intravenous route-accessing devices. 11. The drug delivery device of claim 1, wherein the outlet comprises a fitting for attaching the filter component to a catheter port. 12. The drug delivery device of claim 11, wherein the outlet is rotatable. 13. The drug delivery device of claim 11, wherein the outlet includes a permanent attachment element for forming a permanent attachment with the cathether port. 14. The drug delivery device of claim 1, wherein the blunt needle is non-rigid. 15. The drug delivery device of claim 1, wherein the filter is disposed within a housing disposed between the inlet and the outlet.
