Abstract
A blood collecting bag is clamped along its peripheral edges between two shells. Inlet and outlet ports are formed in one side edge of the bag and are also clamped between the shells. The shells form a vacuum chamber around the bag with the bag serving as a sealing gasket and also house a liquid trap connected to the gas outlet from the bag. Pressure between the two shells is equalized through a vent hole formed through the bag. The bag comprises a membrane forming front and rear faces joined along peripheral edges. The disposable bag includes a laminated filter which lies flat between the front and rear faces of the bag when the bag is collapsed. The filter is sealed between the two faces of the bag along one edge thereof and is joined to the rear face of the bag along its opposite edge to define inlet and outlet chambers. Preferably, the shells are of clear plastic molded to conform to the shape of the expanded bag within the chamber.
