Abstract

Apparatus for blood collection includes a collection bag with a suction inlet, a fluid inlet, and an outlet, and an internal stent that resiliently biases the bag into a fixed shape while moving to modulate abrupt variations in suction level. A gross filter about the outlet is located out of the suction path, eliminating blood damage from drying or cell trauma. Different graduation scales show the true volume of collected fluid under suction conditions during collection and with no suction during reinfusion. Two quick-connects allow in-line connection with a chest drain to provide suction, and mate with each other to close the inlets when the filtered bag is removed for gravity reinfusion. When multiple units are piggy-backed, they fill sequentially and may be removed for reinfusion quickly, with only a single tube reconnection required during surgery.
