摘要：
An apparatus for transferring a liquid between a storage container and at least one further use container has a storage-container sealing portion for leaktight abutment of a main body of the transfer apparatus against the storage container. A hollow-needle assembly has a hollow needle. The hollow-needle assembly can be displaced in a linear manner along a movement axis relative to the main body by means of a gear mechanism between a retracted rest position and an extended connecting position. In the latter, the hollow needle creates a liquid connecting duct between the storage container and the transfer apparatus. A connecting portion serves to connect the transfer apparatus to the use container in a leaktight manner. A rotary-actuation element is operatively connected to the hollow-needle assembly via the gear mechanism. The gear mechanism has a driver ring that is mounted in the main body axially and so as to be rotatable about the movement axis. Said driver ring interacts with a complementary thread of the hollow-needle assembly for the displacement thereof. The driver ring is connected to the rotary-actuation element for conjoint rotation during the displacement. This results in a transfer apparatus having improved operational reliability, in particular when used by inexperienced patients.
