1. An access portal comprising:
- a fluid reservoir configured to receive a portion of an injection device, said fluid reservoir including a base region and at least one sidewall extending upward from said base region to define an open region;
a septum separate from and coupled to said fluid reservoir to seal said open region of said fluid reservoir, said septum having an underside at least partially exposed to said fluid reservoir; and
a plurality of non-movable volume reduction members disposed within said fluid reservoir, said plurality of said volume reduction members each having an upper surface which tapers towards said septum and is configured to contact and deflect a tip of said injection device inserted through said open region and said septum, said plurality of volume reduction members having at least one dimension approximately equal to a distance between said base region of said fluid reservoir and said underside of said septum.

Abstract
An access portal is provided including a housing, a body defining a fluid reservoir, and a septum enclosing the fluid reservoir. A stem in fluid communication with the fluid reservoir extends from the fluid reservoir. The access portal also includes a reservoir insert disposed within the fluid reservoir, in which the reservoir insert decreases the fluid fill volume of the reservoir.

6. An access portal comprising:
-
a fluid reservoir; a septum sealing an open region of said fluid reservoir; a housing defining an opening circumscribing an outer perimeter of said septum, said opening including an angled margin to urge a portion of an injection device towards said septum and into said fluid reservoir; and a plurality of non-movable volume reduction members projecting from only a portion of at least one of a bottom or a sidewall of said fluid reservoir, said plurality of volume reduction members each having an upper surface which tapers towards said septum and is configured to contact and deflect a tip of said injection device inserted through said open region and said septum and configured to reduce a fluid fill volume of said fluid reservoir. - View Dependent Claims (7, 8, 9, 10, 11)
