1. A medical fluid container comprising:
a primary chamber configured to hold a fluid;
a secondary chamber in fluid communication with the primary chamber and partially separated from the primary chamber by a first wall that extends from a top of the medical fluid container to an empty-level near a bottom of the medical fluid container; and
a discharge chamber in fluid communication with the secondary chamber and partially separated from the secondary chamber by a second wall that extends from the bottom of the medical fluid container to a full-level near the top of the medical fluid container,
wherein, when fluid in the primary chamber and the secondary chamber rises above the full-level of the second wall, the fluid within the primary chamber and the secondary chamber empties through the discharge chamber until the fluid in the primary chamber and the secondary chamber drops to the empty-level of the first wall.
