PEN NEEDLE ASSEMBLY

Abstract:

A pen needle assembly includes an adapter (32, 122, 190, 254, 312) and a needle hub (134, 124, 192, 256, 314) coupled to the adapter. The needle hub is removable from the adapter. The adapter has a distal end for coupling with a pen needle delivery device and a distal end with at least one coupling member for coupling with the needle hub. The needle hub is a distal face forming a skin contact surface and a cannula extending from the distal face. The proximal end of the needle hub includes a coupling member for removably coupling with the coupling member of the adapter.
