Abstract
A device serves for transferring a fluid between a storage container and at least one further container for use. Said transfer device comprises a sealing section by means of which a main part of the transfer device sealingly rests on the storage container. A hollow-needle assembly comprises a hollow needle which can be moved between a retracted resting position and a deployed connecting position, the assembly, in the connecting position, providing a fluid connecting channel between the storage container and the transfer device. The hollow-needle assembly can be moved by means of a pressure actuating element. During said movement, the pressure actuating element is primarily connected to the sleeve of the hollow needle so as to be resistant to shear forces. A guiding device serves to axially guide the pressure actuating element on the main part. Said guiding device has at least one guiding pin. Said guiding pin slides in at least one associated guiding groove during movement. The guiding device is designed such that the movement of the hollow-needle assembly from the resting position to the connecting position is irreversible. In this way, the hollow needle can be moved from the resting position to the connecting position in an operationally safe manner.
