| 摘要 |
The invention relates to a device for transferring part of a liquid housed in a container (3), comprising: a hollow needle (5) extending through the stopper of the container; a fluid-pressurisation chamber (8), through which the needle extends and which is provided with a septum (20); and a system (22) for moving the hollow needle (5) and the septum (20) closer together so that the pressure of the fluid increases after they have been moved closer together, said system being controlled so that, in a first phase, it increase the pressure inside the sealed chamber (8) until a transfer pressure is achieved just before the hollow needle (5) passes through the septum (20) and, in a second phase, the hollow needle (5) passes through the septum (20) in order to open into a liquid-dispensing chamber (24) that has a pressure below the transfer pressure. |
