ABSTRACT:
An elongated cylindrical body is provided and includes a diametrically reduced sharpened tubular needle extension on one end for opposing and piercing the puncturable seal of a medicament vial. The other end of the cylindrical body includes a slightly inwardly tapering diametrically enlarged counterbore communicated at its inner end with the interior of the tubular needle extension. The body is provided for support from a safety cap secured over the conventional closure of a medicament vial provided with a puncturable seal with the needle structure guidingly supported from a central tubular mounting portion of the safety cap outwardly of the puncturable seal of the vial for movement of the sharpened tubular needle extension toward, in engagement with and through the puncturable seal, whereby the conical tip of a syringe to have medicament introduced thereinto from the medicament vial may be seated within the inwardly tapering counterbore in fluid-tight sealed engagement therewith and the needle structure may be used to transfer medicament from within the vial into the syringe. The sharpened terminal end of the tubular needle extension is of a configuration other than the usual planar bevel to ensure the ability of the sharpened terminal end of the needle extension to retain its shape under axial pressure upon its engagement with the puncturable seal of a medicament vial, even when the needle structure is constructed of inexpensive plastic for manufacture by means of relatively inexpensive high volume molding manufacturing processes.
