Abstract
An infusion device for medical purposes is described, comprising a container (10) with at least two chambers (14, 16), with their openings (20, 22) closable by means of sealing stoppers, in particular by a common stopper (12). The sealing stopper has a cavity (34) in the area of the opening (20) of the first chamber (14) which communicates with the second chamber (16). A cannula (42) may be pierced through the stopper (12) in the area of the opening (20) of the first chamber (14) and can simultaneously receive infusional solutions from the two chambers through two orifices (44, 46) spaced longitudinally from one another. The connection between the cavity (34, 40) in the stopper (12) may be established in one embodiment by means of a connecting cannula (56) with orifices (58, 60).
