Claim:
1. An access port comprising: a base comprising: a proximal end; a distal end; a proximal fluid reservoir comprising a bottom wall at a bottom of the proximal fluid reservoir, the proximal fluid reservoir disposed at the proximal end of the base; a distal fluid reservoir comprising a bottom wall at a bottom of the distal fluid reservoir, the distal reservoir disposed at the distal end of the base; a dual prong outlet stem projecting from the distal end of the base, the dual prong outlet stem comprising a first prong comprising a first distal tip, and a second prong comprising a second distal tip; a first fluid channel extending from the first prong, the first fluid channel providing a first fluid pathway from the first distal tip of the first prong to the distal fluid reservoir; a second fluid channel extending from the second prong, the second fluid channel providing a second fluid pathway from the second distal tip of the second prong to the proximal fluid reservoir, a portion of the second fluid channel disposed in the bottom wall of the distal fluid reservoir beneath the distal fluid reservoir; and a puncture shield embedded in the distal end, at least a portion of which is disposed in the bottom wall of the distal fluid reservoir between the distal fluid reservoir and the second fluid channel to protect against penetration into the second fluid channel, wherein the puncture shield comprises a flat planar portion, a first end having a D-shaped cross section, and a second end having a D-shaped cross section, wherein the first end and the second end are connected by the flat planar portion, and the first end extends into a distal wall of the distal fluid reservoir and the second end extends into a proximal wall of the distal fluid reservoir; a first needle-penetrable septum disposed atop the distal fluid reservoir; a second needle-penetrable septum disposed atop the proximal fluid reservoir; and a cap securing the first and second needle-penetrable septa to the base, thereby forming a fluid seal between the first septum and the distal fluid reservoir and between the second septum and the proximal fluid reservoir, the cap comprising:
