Abstract
Plastic blood bag system including a bag having a generally longitudinal seal extending from the top of the bag and between two blood bag ports downwardly to at least the lower half of the bag but not to the bottom of the bag, thereby leaving the sole passageway within the bag and between two ports located in the lower half of the bag. The longitudinal seal terminates proximal to the central axis of the bag with a spot weld to prevent tear. In addition, the cross-sectional diameter of the channel increases as the channel nears the central axis.
