ABSTRACT:
An injection set with a slit septum held in place in the inlet of a housing by a cap affixed to the inlet. A concave end of the septum is exposed through an aperture in the cap, and a peripheral flange portion of the septum is squeezed between the housing inlet and the cap, causing the septum's concave end to bulge and flatten, thus improving the sealing of the septum's slit. Extending through the septum slit is a drug transfer spike having a ball-shaped tip sharp enough to penetrate the diaphragm of a drug vial but not so sharp as to puncture the skin of a user.
