Abstract
An apparatus for use in connection with removal of elements, especially exogenous antibodies, from blood or plasma flowing in an extracorporeal blood circulation system of a patient, where said apparatus comprises a container ( ). This container is adapted to receive an adsorbent and comprises an inlet ( ) and an outlet ( ) which are adapted to be connected to an inlet conduit ( ) and an outlet conduit ( ), respectively, forming part of the blood circulation system. The container ( ) comprises an inlet chamber ( ), an adsorption chamber ( ) adapted to receive the adsorbent, and an outlet chamber ( ). These chambers are arranged in sequence when seen in the flow direction of the blood or the plasma through the container ( ) and are separated by means of filter units ( ) allowing passage of the blood or the plasma. The inlet ( ) and the outlet ( ) are arranged adjacent one another in connection with a common movable valve means ( ). The valve means is adapted so as in a first position to connect the inlet ( ) and the outlet ( ) directly with their respective passages ( ) in the container wall ( ) and so as in a second position to connect said inlet ( ) and said outlet ( ) with their respective ends of a bypass-forming channel ( ) in the container wall ( ). The passage ( ) associated with the inlet communicates with a transfer channel ( ) ending in the inlet chamber ( ), whereas the passage ( ) associated with the outlet ( ) is open into the outlet chamber ( ).
