A connector device for conveying a sterile fluid medication housed within a cylindrical container, such as a syringe or pre-filled cartridge having a sharp hollow needle attached thereto, into a needle-penetrable intravenous (IV) access port on an intravenous IV infusion system. The device enables the transfer of medicament from within the cylindrical container into the IV access port without hazardous exposure of the sharp hollow needle or bacterial contamination of the IV access port. The connector device is a hollow tubular structure having a length, a conical or cylindrical leading axial bore, and a conical trailing axial bore. The leading bore is dimensioned to snugly accept a portion of the infusion limb of the IV access port into a fixed recessed position. The trailing conical bore is dimensioned to accommodate and wedge impact a portion of the cylindrical medication container. When the leading portion of the cylindrical container is wedge impacted into the trailing conical bore and can be advanced no further thereinto, the sharp hollow needle attached thereto penetrates the recessed portion of infusion limb of the IV access port, such that the medication can be transferred from the container into the port. On completion of the transfer, the connector device is removed from the IV access port still containing the wedge impacted cylindrical container whereupon the attached needle remains safely recessed in the leading axial bore of the connector device. The connector device containing the safely recessed needle and wedge impacted cylindrical container, then, become safely disposable as a unit. Compared with needleless IV access ports having on-line recesses prone to bacterial colonization, this connector device maximizes the efficient sterile use of inserted sharp hollow needles at low costs.
