<p>An IV injection site (10; 10A) adapted to receive a blunt cannula (12). The injection site (10; 10A) comprises a housing (16; 16A) having a passageway (20; 20A) extending inwardly from its outside end (18; 18A), and an elastomeric septum (22; 22A) closely received in the passageway of the housing (16; 16A). The septum (22; 22A) has a bore (28; 28A) extending into the septum (22; 22A) from the inside end (24) of the septum (22; 22A) but not through the septum, and a slit extending generally in the axial direction into the septum (22; 22A) from the outside end (18; 18A) of the septum (22; 22A) to the bore (28; 28A). When a cannula (12) is introduced through the slit (30; 30A) of the septum (22; 22A), the elastomeric material of the septum (22; 22A) is displaced into the bore (28; 28A) of the septum (22; 22A) to sealingly engage the cannula (12) along the bore (28; 28A) of the septum (22; 22A).</p> |
