The drainage pump unit according to the invention for aspirating body fluids by means of a suction pump comprises a drainage pump device with a pump housing (4) for receiving the suction pump, and a fluid collection container (5) that can be secured releasably on the pump housing (4). The drainage pump unit also comprises a pump-side attachment part (2) which has a connection element for connection to a patient-side drainage tube (10). The attachment part (2) is held releasably on the pump housing (4), and it has a connector piece (20) onto which an attachment opening (5) of the fitted. Alternatively, the attachment part (2) can have an attachment opening into which a connector piece of the fluid collection container (5) can be inserted. The connection element and the connector piece (20) or attachment opening are connected to each other via a drainage channel (24) extending through the attachment part (2). This drainage pump unit allows the fluid collection container to be replaced without removing the draining tube and, therefore, without disturbing the patient.根據本發明之用於藉著吸入泵吸出身體流體的排水泵組件包含一個排水泵裝置，其具有用於接收該排水泵的泵外殼(4)及一流體收集容器(5)，該容器係以可釋放的方式被緊固在該泵外殼(4)上。前述排水泵組件也包含一個泵側接附部件(2)，其具有一個用於連接到一個病人側排水管(10)的連接元件。該接附部件(2)以可釋放方式被保持在該泵外殼(4)上，以及該接附部件(2)具有一連接器件(20)，該流體收集容器(5)的一個接附開口(54)可以被安裝在該連接器件上。或是，該接附部件(2)可以具有一個接附開口，該流體收集容器(5)的一個連接器件可以被插入該接附開口中。連接元件和前述連接器件(20)或接附開口係經由一個延伸進入該接附部件(2)的一個排水通道(24)連接於彼此。排水泵組件係容許流體收集容器可以在沒有移除排水管的情況下被更換或清空，且因此不會干擾到病人。
