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.
Core Innovation
The disclosure relates to a drainage pump unit for aspirating body fluids by means of a suction pump. The drainage pump unit 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.
A pump-side attachment part is provided with a connection element for connection to a patient-side drainage tube. The attachment part is held releasably on the pump housing and has either a connector piece onto which an attachment opening of the fluid collection container can be fitted, or an attachment opening into which a connector piece of the fluid collection container can be inserted.
The connection element and the connector piece of the attachment part or the attachment opening of the attachment part are connected to each other via a drainage channel extending through the attachment part. In this arrangement, the fluid collection container can be removed from the pump housing without the attachment part, including the connection element and the connector piece, or the attachment opening having to be removed from the pump housing.
Claims Coverage
The partial content provides one independent claim (clm-00001). It contains a set of inventive features centered on releasable attachment of the fluid collection container via a pump-side attachment part with a drainage channel that enables removal of the container without removing the attachment part.
Releasably secured fluid collection container on pump housing
A drainage pump device with a pump housing receiving the suction pump and a fluid collection container that can be secured releasably on the pump housing.
Pump-side attachment part held releasably on pump housing and connectable to patient-side drainage tube
A pump-side attachment part with a connection element for connection to a patient-side drainage tube, wherein the attachment part is held releasably on the pump housing.
Connector/attachment-opening interface between attachment part and fluid collection container
An arrangement in which the attachment part has a connector piece onto which an attachment opening of the fluid collection container can be fitted, or the attachment part has an attachment opening into which a connector piece of the fluid collection container can be inserted.
Drainage channel through the attachment part connecting connection element and container interface
The connection element and the connector piece of the attachment part or the attachment opening of the attachment part being connected to each other via a drainage channel extending through the attachment part.
Container removal without removing the attachment part
The fluid collection container can be removed from the pump housing without the attachment part, including the connection element and the connector piece, or the attachment opening having to be removed from the pump housing.
Across clm-00001 and the dependent claim refinements mentioned in the partial content, the claim coverage is directed to a drainage pump unit in which a releasably retained pump-side attachment part provides a drainage-channel connection between a patient-side drainage tube and a corresponding container opening/connector, so that the fluid collection container is removable without removing the attachment part.
Stated Advantages
Enables releasable replacement/emptying of the fluid collection container without disconnecting the patient-side drainage tube.
Documented Applications
Drainage pump unit for aspirating body fluids, including situations where a fluid collection container is to be removed from the pump housing without removing the attachment part.
