The invention relates to a method and an apparatus for collecting and transporting liquids, for example blood, into one or more closed packages, for instance so called transfer bags (11, 12), or alternatively, directly transfering the blood into another liquid system, for instance a heart-lung machine, without any admixture of air or any other gas or gas mixture. The blood is collected without contact by human hand and without contamination of the blood and under sterile conditions. The apparatus comprises a suction nozzle (4) for sucking up the liquid or a liquid/air/gas mixture, a suction hose (5) for directing the liquid to a defoaming separator (7) for separating air from the liquid, and a recipient (8) in which the deacrated liquid is filtered and collected. When a certain volume has been collected, the liquid is directed without introducing air into said closed packages (11, 12) or communicated to another liquid system. The recipient (8) comprises a replaceable, flexible so-called canister bag (9) for collecting the liquid and arranged in a stiff, closed container (10) and provided with filters (17, 18) as well as filling and tapping conduits (22, 23). The recipient (8) and the corresponding packages (11, 12) are connected to the suction source (1) of the system for filling and tapping of the liquid.
