Locking mechanism

A coupling part of a drainage tube unit for aspirating body fluids by a suction pump includes a patient-side drainage attachment, a pump-side drainage orifice for connection to a drainage tube, and a drainage channel connecting the drainage attachment and the drainage orifice to each other. The coupling part also includes a pump-side first service orifice for connection to a service tube, a second service orifice ending in the interior of the coupling part, a service channel connecting these first and second service orifices, and a device which separates the service channel from the drainage channel. The device permits delivery of fluid from the service channel into the drainage channel and prevents delivery of particles and liquid from the drainage channel into the service channel. The device is arranged in the coupling part at a location that allows a flow through the drainage channel from the drainage attachment to the drainage orifice without passage through the device.

Coupling part of a drainage tube unit

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 () for receiving the suction pump, and a fluid collection container () that can be secured releasably on the pump housing (). The drainage pump unit also comprises a pump-side attachment part () which has a connection element for connection to a patient-side drainage tube (). The attachment part () is held releasably on the pump housing (), and it has a connector piece () onto which an attachment opening () of the fluid collection container () can be fitted. Alternatively, the attachment part () can have an attachment opening into which a connector piece of the fluid collection container () can be inserted. The connection element and the connector piece () or attachment opening are connected to each other via a drainage channel () extending through the attachment part (). This drainage pump unit allows the fluid collection container to be replaced without removing the drainage tube and, therefore, without disturbing the patient.
