ABSTRACT:
A blood collecting and filtering apparatus comprises a container (1) defining with a removably fixed cover (2) a tightly closed enclosure. The cover (2) is provided with an adjustable device (6) for connecting to a reduced pressure system and has a traversing opening (4). A disposable flexible filtration bag (10) is disposed in service position inside said enclosure. The bag has two internal rooms (13, 14) separated the one from the other by a filtering wall (12). The first room (13) is connected to the outside by an inlet pipe (15) for feeding blood to be treated, and the second room (14) is connected to the outside by an outlet pipe (16) for filtered blood. The second room has an opening which is closed by an element (17) made of a material which is permeable to air and impervious to liquids. Both inlet (15) and outlet (16) pipes pass in a tight manner through a plug (21) which in service position closes the traversing opening (4 ) of the cover (2).
