Inventors: BRUCE E. BARNES WILLIAM W. DUPIN BRUCE W. KUHLEMANN Invention: PIVOTING FRANGIBLE VALVE FOR BLOOD BAGS Abstract of the Disclosure Frangible valve for a closed blood bag system comprising an upper member having a bore and located within a port on a blood bag and a solid lower member extending into the bag. The lower member is attached to the upper member by at least one tether and includes a bore-sealing portion attached to the upper member via a weakened portion. In use, the bore-sealing portion is separated from the upper member by external manipulation to permit fluid flow through the bore while the bore-sealing portion remains tethered to the valve. In preferred embodiments, two tethers are included on opposite sides of the bore-sealing portion and the tethered bore-sealing portion includes means for keeping it separated from the bore in a fully open position after the bore seal has been broken.
