The present invention relates to a method and apparatus for aspiration of secreted fluids from a wound by means of a drain that is connected with a container by a tube, in which the container is a negative pressure, which decreases with the flow of secreted fluid, and regenerates from time to time to a selectable value. A closed system formed by the drain, the container and the tube connecting the two is supplemented for this purpose with a collection container and a second tube that connects the collection container with the container. The second tube has at least one section to which a tube pump can be applied. A clamp is provided in the line formed by the second tube between the container and the collection container. |
