Apparat til brug ved fjernelse af bestanddele, især eksogene antistoffer, fra blod eller plasma

摘要

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 (1). This container is adapted to receive an adsorbent and comprises an inlet (15) and an outlet (16) which are adapted to be connected to an inlet conduit (19) and an outlet conduit (20), respectively, forming part of the blood circulation system. The container (1) comprises an inlet chamber (31), an adsorption chamber (32) adapted to receive the adsorbent, and an outlet chamber (33). These chambers are arranged in sequence when seen in the flow direction of the blood or the plasma through the container (1) and are separated by means of filter units (11, 12) allowing passage of the blood or the plasma. The inlet (15) and the outlet (16) are arranged adjacent one another in connection with a common movable valve means (21). The valve means is adapted so as in a first position to connect the inlet (15) and the outlet (16) directly with their respective passages (28, 29) in the container wall (4) and so as in a second position to connect said inlet (15) and said outlet (16) with their respective ends of a bypass-forming channel (34) in the container wall (4). The passage (28) associated with the inlet communicates with a transfer channel (30) ending in the inlet chamber (31), whereas the passage (29) associated with the outlet (16) is open into the outlet chamber (33).
