Abstract
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 (54) of the fluid collection container (5) can be 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 drainage tube and, therefore, without disturbing the patient.
