ABSTRACT:
The invention refers to a method of mixing, for example, cytostatica stored in an ampule (1) provided with a rubber closure (8) or corresponding closure, with, for example, sterile water stored in a second ampule (2) provided with a rubber closure (12) or corresponding closure. The invention is characterized in that a first tube (7) of hypodermic needle shape, which is connected by a hose connection (6) to a first port (5) of a multi-way valve (4), is pierced through the rubber closure (8) of one ampule (1), that a second tube (11) of hypodermic needle shape, which is connected by a hose connection (10) to a second port (9) of the multi-way valve (4), is pierced through the rubber closure (12) of said second ampule (2). The interior of the ampules is interconnected by a hose connection (13), the two respective ends of which have the shape of hypodermic needles (14,15) and are pierced each through one rubber closure (8,12). A pump means in the form of a self-expanding bellows (23) or hypodermic syringe (17) is connected to a third port (16) of the multi-way valve (4). By said pump means (17,23) and alternating adjustment of the multi-way valve (4), the substance in one ampule (2) is transferred to the second ampule (1), in which the two substances are mixed with each other, and the mixture is sucked into the pump means (17,23).
