| 摘要 |
The invention relates to a device for the preparation of a medicinal solution from two compounds, one of which is in the form of a powder, a lyophilisate or a liquid and the other one is a diluent or a liquid solvent. These compounds are respectively stored in a distal closed container (11) and a proximal container (13), each having an opening sealed by an obturator-piston-valve, which isaxially movable. The two obturators-pistons-valves (19, 24) are connected by a transfer rod (15) arranged to provide for a rigid, sealed and sterile couplind link between the two obturators-pistons-valves (19, 24) when the device (10) is in a storage position, and to define a liquid-tight and sterile communication channel between the two containers (11, 13) when the device is in a utilisation position. The obturators-pistons-valves (19, 24) have a central area provided with a slot (31, 33) which is highly compressed and sealingly closed when the device is in a storage position, and opened when an extremity of the transfer rod (15) is inserted therein, the device being then in the utilisation position. |
