Dialysis bag with anti-occlusion feature

A peritoneal dialysis bag, comprising:

• a bag chamber defined by a pair of complementary layers sealed together to form a bag chamber therebetween and having a first, outlet end and a second, closed end opposite said outlet end;
• said bag layers sealed together in part at said outlet end by a first outlet end seal;
• at least one tubular administrative outlet sealingly disposed at said outlet end and in fluid communication with said bag chamber, said outlet having an inlet projecting into said bag chamber past a seal joining said bag layers together;
• said seal including a linear, axially extending seal segment extending in spaced, parallel relation to said outlet and into said bag chamber to create a displacement between an end of said segment and said inlet;
• and a dimple formed in at least one said layer, having a length and a width, the length being longer than said width and, said dimple having a first end adjacent said inlet of said outlet and a second end adjacent said end of said seal segment of said first outlet end seal for preventing occlusion of said inlet as said bag is depleted of fluid, said dimple located only along a line extending between said inlet and said end of said segment.

A peritoneal dialysis bag, comprising:

• at least one tubular administrative outlet sealingly disposed at an outlet end of a bag chamber and in fluid communication with said bag chamber, said outlet having an inlet projecting into said bag chamber past a seal joining said bag layers together;
• a dimple formed in at least one said bag layer and having a first end adjacent said inlet and a second end adjacent an end of an axially extending segment of a first outlet end seal, wherein said dimple extends only along a line between said inlet and said seal segment end, said first outlet end seal being asymmetrical with a second outlet end seal, said axially extending segment of said first outlet end seal extending further axially into said bag chamber than said inlet of said first outlet seal and also further axially relative to said second outlet end seal;
• said inlet is closer to said first outlet end seal than to said second outlet end seal;
• and a generally “L”-shaped support rib being disposed relative to said first outlet end seal such that said seal portion is located between said rib and said tubular administrative outlet.
