Patent ID: 8267912

Claim:
An infusion bag comprising: a body having a top wall and a single interior space for holding a fluid, the interior space being defined by a pair of parallel side walls and an inner wall and an opposite non-planar, tapered bottom wall, the inner wall extending across the body from one side wall to the other side wall such that a first angle α 1 is formed between a first end of the inner wall and one side wall and a second angle α 2 is formed between a second end of the inner wall and the other side wall, the first angle being different from the second angle, wherein inner surfaces of the parallel side walls are planar from the top wall to the bottom wall and the interior space is continuous and uninterrupted from the inner wall to the bottom wall across the entire width of the body; a needleless port that protrudes outwardly from the other side wall, below the top wall, and is in fluid communication with the interior and is configured to sealingly mate with an external device, the needleless port being configured and positioned within the body for both delivering a fluid to the interior space and for alternatively airing the interior space, wherein the needleless port is disposed in an upper corner of the body where the second end of the inner wall intersects the other side wall, wherein the angled inner wall and location of the needleless port combine to promote airing of the bag through the needleless port; and at least one other port that is in at least selective communication with the interior space and is located along the bottom wall, wherein each port formed along the bottom wall is located entirely below locations where the parallel side walls intersect and join the bottom wall; wherein the body has only two openings formed in the body for hanging the bag, the two openings being formed in an asymmetric manner across a width of the body, with one opening being formed proximate the second top corner of the body at an offcentered location for hanging the bag at an angle to promote airing of the bag, wherein the other opening is formed in a center of the body such that the body is free of an opening in a location proximate the first top corner so as to prevent the bag from being hung by the first top corner.
