Abstract
An IV injection site adapted to receive a blunt cannula. The injection site comprises a housing having a passageway extending inwardly from its outside end, and an elastomeric septum closely received in the passageway of the housing. The septum has a bore extending into the septum from the inside end of the septum but not through the septum, and a slit extending generally in the axial direction into the septum from the outside end of the septum to the bore. When a cannula is introduced through the slit of the septum, the elastomeric material of the septum is displaced into the bore of the septum to sealingly engage the cannula along the bore of the septum.
