Abstract
A method of making an injection and sampling site adapted to receive a blunt cannula. The method comprises providing an elastomeric septum, and a housing adapted to receive that septum; making a slit in the elastomeric septum; inserting the elastomeric septum into the passageway of the housing; and swaging an outer annular ledge on the housing inwardly over the septum until a septum-engaging portion of the swaging tool applies a predetermined amount of force to the septum. Before the swaging step, a pin is inserted into the passageway of the housing against the inside end of the septum to inhibit deformation of the septum during swaging.
