Abstract

The invention relates to a method and an apparatus for collecting and transporting liquids, for instance blood, while at the same time dosing an additive, for instance an anticoagulent agent, in an accurate proportion to the amount of the collected liquid. The liquid or a liquid/air/gas mixture is sucked up by means of a suction nozzle (4) and transported through a suction hose (5). A dosage device (6) comprising an exchangeable, flexible container (23) with said dosing additive, for instance a CPD bag, is connected to the suction hose whereby the pressure levels in the apparatus, provided by connecting the apparatus to a vacuum pump (1), are adjusted in such a way relative to each other that no additive at all is introduced when only air/gas is sucked up in the suction nozzle, whereas dosing additive is introduced into the suction hose (5) as soon as liquid is sucked through the suction nozzle (4) so that the amount of dosage additive is in proportion to the amount of sucked liquid. The invention is characterized by connecting the positive pressure side (30) of the suction source (1) to a pressure bag (31) in order to apply the necessary pressure on the CPD-bag (23), for dosing as soon as liquid has been sucked up by the suction nozzle (4).
