A method of filling a container with fresh blood components, the method comprising the following steps: a) at least a first gap (3a) coupled to a bag (5) or the like containing fresh blood components, a plurality of A transfer channel (3) having at least a second gap portion (3b) connected to the filled container (6) and at least a third gap portion (3c) connected to the pressure feeding means (12) is defined. Providing one device (1)； b) separating the first gap (3a) from the second gap (3b) and bringing the second gap (3b) into communication with the third gap (3c). Placing step； c) sucking air contained in the filled container (6) using the pumping means (12), thereby defining a vacuum space in the container (6)； d) first The gap (3a) is placed in communication with the second gap (3b), and the container (6) Aspirating the contents of the bag (5) by the action of the vacuum space defined by； the flow path (3) comprises at least a fourth gap (3d) coupled with an empty syringe (4) etc. And after the step d), the method comprises the following steps: e) separating the first gap (3a) from the second gap (3b) and replacing the first gap itself with the fourth gap ( 3d) placing in communication with f； f) using the syringe (4) to remove at least a portion of the contents of the bag (5)； g) the fourth gap (3d) to the first gap ( Separating from 3a) and placing the fourth gap itself in communication with the second gap (3b)； h) sending the contents removed by the syringe (4) into the container (6) ,Method.
