PCT No. PCT/CH93/00282 Sec. 371 Date Jul. 19, 1994 Sec. 102(e) Date Jul. 19, 1994 PCT Filed Dec. 15, 1993 PCT Pub. No. WO94/13344 PCT Pub. Date Jun. 23, 1994The invention concerns a device for the preparation of a medicinal solution from two components, one of which is in powder, lyophilisate or liquid form and the other a dilutant or a liquid solvent. These components respectively are charged in a rear container (11) and a front container (13), each of which has an opening closed off by a stopper-piston-dish, which is axially movable. Both these stopper-piston-dishes (19, 24) are connected by a conveyance shaft (15) adapted to ensure a rigid, tight and sterile coupling between the two stopper-piston-dishes (19, 24) when the device (10) is in a charging position, and to define a channel between both these containers (11, 13) when the device is in a position of use. The stopper-piston-dishes (19, 24) have a central zone provided with a slit (31, 33)m which is strongly compressed and closed in tight fashion when the device is in charging position, and which is open when one end of the conveyance shaft (15) is introduced therein, the device then being in the position of use.
