    摘要： An injection or sampling site adapted to receive a blunt cannula includes a housing having an outside end with a passageway extending inwardly from the outside end, the passageway defining an axial direction; and an elastomeric septum closely received in the passageway of the housing. There is a slit extending through the septum generally in the axial direction which is formed by a hole through the septum that is flattened against itself to seal against itself when the septum is assembled in the housing. Either the septum-receiving portion of the housing or the septum itself has a generally elliptical cross-section to preferentially compress the hole in the septum to form the slit.
