Abstract:
The method for the preparation of containment units of biological liquids, comprises the following stages of: furnishing a device (1) comprising a main body (2) which defines at least a continuous filling channel (3), having at least an inlet gap (3a) of a biological liquid and at least an air outlet gap (3b), a plurality of containment units (4) arranged in succession to one another so as to communicate with each other and defining respective containment chambers (5) positioned along the filling channel (3) and placed in between the inlet gap (3a) and the outlet gap (3b), a hydrophobic air filtering device (6) associated with the body (2) in correspondence to the outlet gap (3b), wherein the containment units (4) are bulbous members each having opposing elastically deformable sides that define the respective containment chambers therebetween, and wherein after deformation the sides return to a convex non-deformed idle configuration in which the sides are at a non-zero distance from one another;injecting a biological fluid along the channel (3) through the inlet opening (3a) so as to push towards outside the air contained inside the containment chambers (5) through the outlet gap (3b) and to gradually filling the containment chambers (5) which it crosses;closing and isolating the containment units (4) the one from the other.
