Pre-slit injection site

An injection site usable with a blunt cannula comprising:

• a housing defining a fluid flow channel therethrough, said housing having a first end and a second end;
• a resilient sealing means, carried by said housing overlying said channel, for sealing said first end, said sealing means being formed with a resealable opening therein extending at least partway therethrough and an exterior peripheral surface;
• a retaining means for retaining said sealing means in said housing such that a cannula can be sealingly inserted through said opening and placed in fluid flow communication with said flow channel and such that the cannula can be removed therefrom with said sealing means interacting with said retaining means so as to reseal said opening, said retaining means including a deformation of said housing first end against said exterior peripheral surface of said sealing means, said first end deformation applying axially directed forces to said sealing means;
• a coupling component integral with said second end and continuing said fluid flow channel, said coupling component having a spike with a barb member, said spike capable of being inserted into a drug vial and provide drainage of the vial fluid through said fluid flow channel.
