Abstract: A dual reservoir access port (18) includes a metal casing (28) having open proximal and distal fluid reservoirs (30, 34). A dual prong metal outlet stem (36) projects from the casing (28) on the side of the distal fluid reservoir (34) opposite from the proximal fluid reservoir (30). The distal fluid reservoir (34) is carried within an open basket (32) that is disposed in a receiving cup (31) in the top (118) of the casing (28). A first fluid flow pathway (162) extends from the proximal fluid reservoir (30) to the outlet stem (36) between the basket (32) and the wall (36) of the receiving cup (31). A second fluid flow pathway (80) extends directly from the distal fluid reservoir (34) to the outlet stem (36). A needle-penetrable compound septum (38) disposed against the casing (28) over the open fluid reservoirs (30, 34) is clamped against the casing (28) by a plastic jacket, compressing the periphery of the septum (38) and sealing each of the fluid reservoirs (30, 34).
