Abstract
A disposable sterile apparatus (1) for blood filtration with a system for the optimization of blood recovery in the passage from one pouch to the next, having a main tube (4, 8, 13, 18, 19) containing sterile air, one end of which is designed for the connection to a first container (pouch) (2) containing the liquid to be filtered and the other end of which is connected to a second empty container (pouch) (20). The foregoing tube (4, 8, 13, 18, 19) includes at least one filter (12) being arranged in the flow of the liquid. The apparatus (1) contains a tube (7) for the return of air from the second (20) to the first container (2) acting to equalize pressure of the liquid at the two extremities of the main tube (4, 8, 13, 18, 19) after the liquid has been filtered. The filter (12) features two interior semi-chambers with filtration material separating them. The first semi-chamber has an inlet port while the second semi-chamber has an outlet port and a venting port. Tubing (14) allows the venting port to communicate with the end of the main tube connected to the first container (2) so that the filter may be emptied.
