Patent ID: 7784997

Claim:
A closed single-use system for mixing, storing and homogenizing liquids, comprising: a rigid container ( 1 ) fitted with a non-invasive pump ( 4 ), said container ( 1 ) enclosing a generally parallelepipedic single-use bag ( 2 ), wherein the lower face of the bag includes an orifice for the liquid to discharge to the outside of the bag, the upper face includes an orifice for the liquid to return through which said liquid returns to the inside of the bag, said orifices being connected in fixed manner by an external mixing duct ( 3 ) which is inserted into the pump ( 4 ) which, during operation, allows the closed-circuit circulation of the liquid taken from the bottom of said bag ( 2 ), the pump ( 4 ) being open so that the mixing duct ( 3 ) is insertable into and extractable from the pump, wherein the mixing duct is connected to the upper face of the single-use bag so that the mixing duct discharges directly into an upper-most part of the bag, and wherein the mixing duct is connected to the lower face of the single-use mixing bag so that the mixing duct takes in fluid directly from a lower-most part of the bag opposite the upper-most part.
