<p>A cannula is disclosed for transferring fluid relative to a vial or intravenous port having an elastomeric membrane. The cannula includes a blunt solid penetration tip and one or more ports intermediate opposite ends of the cannula in communication with a passage opening into a Luer fit or a Luer lock for securing the cannula to the tip of a syringe. Indicia on the cannula between the proximal end and the ports represent a predetermined distance substantially corresponding to the extent of penetration of the side port of the cannula body through the membrane necessary to locate at least a portion of the side port on the opposite side of the membrane from the second end and directly adjacent the membrane.</p> |
