An apparatus for transferring a liquid between a storage container and at least one further use container has a storage-container sealing portion (4) for leaktight abutment of a main body (5) of the transfer apparatus against the storage container (2). A hollow-needle assembly (9) has a hollow needle (10). The hollow-needle assembly (9) can be displaced in a linear manner along a movement axis relative to the main body (5) by means of a gear mechanism (12) between a retracted rest position and an extended connecting position. In the latter, the hollow needle (10) creates a liquid connecting duct between the storage container (2) and the transfer apparatus. A connecting portion (16) serves to connect the transfer apparatus to the use container in a leaktight manner. A rotary-actuation element (20) is operatively connected to the hollow-needle assembly (9) via the gear mechanism (12). The gear mechanism (12) has a driver ring (25) that is mounted in the main body (5) axially and so as to be rotatable about the movement axis. Said driver ring (25) interacts with a complementary thread (27) of the hollow-needle assembly (9) for the displacement thereof. The driver ring (25) is connected to the rotary-actuation element (20) for conjoint rotation during the displacement. This results in a transfer apparatus having improved operational reliability, in particular when used by inexperienced patients.一種用於在儲存容器與至少一另一使用容器之間傳送液體的設備有一儲存容器密封部(4)用於使該傳送設備之一主體(5)防漏地抵頂該儲存容器(2)。中空針總成(9)有中空針(10)。藉由一齒輪機構(12)，該中空針總成(9)相對於該主體(5)可在縮回靜止位置與伸出連接位置之間以線性方式沿著一運動軸線移位。在處於該伸出連接位置時，該中空針(10)在該儲存容器(2)與該傳送設備之間建立一液體連接導管。連接部(16)用來使該傳送設備以一防漏方式連接至該使用容器。旋轉啟動元件(20)經由該齒輪機構(12)可操作地連接至該中空針總成(9)。該齒輪機構(12)有一驅動環(25)軸向裝在該主體(5)中以便可繞著該運動軸線旋轉。該驅動環(25)與該中空針總成(9)的一互補螺紋(27)互動用於使其移位。該驅動環(25)在移位期間連接至該旋轉啟動元件(20)以用於聯合旋轉。這導致傳送設備有改良的操作可靠性，特別是在被無經驗患者使用時。
