housing are threaded. One threaded end 18a is employed for
connecting it to the center body 16. The other threaded end
18b is employed
for securing a double ended needle assembly 50. Needle
assembly 50 includes a cannula 50a having a sharp distal end
50b for piercing the skin of the user and a sharp proximal end
50c for piercing seal 46a of the cartridge and a lumen (not
shown) therethrough. Needle assembly 50 includes a cup shaped
hub 50d holding said cannula so that the sharp proximal end
projects outwardly from the interior of the cup-shaped hub.
The cup-shaped hub includes an internal thread which is
compatible with the thread at 18a so that the needle assembly
may be removably attached to housing 18 with its sharp
proximal end piercing pierceable seal 46a to establish fluid
communication between said lumen and the interior of said
cartridge.
The pertinent teachings of Ben Moura have been set forth
previously in our discussion of the anticipation rejection.
