ABSTRACT:
An injection site and unsharpened drug transfer spike for facilitating coupling a syringe to a fluid line. The injection site has a uniquely designed housing and septum comprised of only two parts. The drug transfer spike has a positive locking member for restricting retraction from the injection site once it is inserted for injecting a medicant. The positive locking member preferably comprises a annular ridge defined about the shaft of the drug transfer spike. The septum includes a pair of axially aligned, oppositely oriented conical recesses with adjacent apices either separated by a thin membrane or intersecting at the time of manufacture. The housing has an inlet for receiving the septum and comprises a plurality of fingers with inwardly extending tabs for constraining the septum therewithin. The septum is ideally adapted to be applied to injection sites, Y-connectors, vial adaptors, single or multi-dose vials and blood collection tubes. When the drug transfer spike is made to penetrate the septum, the walls of the septum or the inwardly extending tabs tightly engage the shaft of the spike to preclude inadvertent withdrawal.
