Chamber for a blood treatment system, blood tubing system, and blood treatment system

Abstract

The present invention relates to a chamber for a blood treatment system having a blood inlet and a blood outlet, a filter element for air separation which is arranged at the head side with respect to the position of the chamber in the operating state and which can be decoupled from the blood present in the chamber in the operating state by means of a further liquid, to a blood hose system and to a blood treatment system.

 characterized in that   a filter element ( 26 ) for air separation is provided which is arranged at the head side with respect to the position of the chamber in the operating state and which can be decoupled from the blood (B) present in the chamber ( 10 ) by a further liquid (D) in the operating state, with the blood inlet being arranged at the head side.   
     
     
         2 . A chamber ( 10 ) in accordance with  claim 1 , characterized in that the blood outlet ( 24 ) is arranged in the chamber ( 10 ) at the base side with respect to the position of the chamber ( 10 ) in the operating state. 
     
     
         3 . A chamber ( 10 ) for a blood treatment system having a blood inlet ( 22 ) and a blood outlet ( 24 ),
 characterized in that,   a filter element ( 26 ) for air separation is provided which is arranged at the head side with respect to the position of the chamber ( 10 ) in the operating state and which can be decoupled from the blood (B) present in the chamber ( 10 ) by a further liquid (D) in the operating state, with the further liquid (D) being able to be supplied by means of a supply port ( 28 ).   
     
     
         4 . A chamber ( 10 ) for a blood treatment system having a blood inlet ( 22 ) and a blood outlet ( 24 ) and having a filter element ( 26 ) for air separation which is arranged at the head side with respect to the position of the chamber ( 10 ) in the operating state and which can be decoupled from the blood (B) present in the chamber ( 10 ) by a further liquid (D) in the operating state, with the further liquid (D) being able to be supplied by means of a supply port ( 28 ), characterized in that the chamber ( 10 ) has the characterizing feature of  claim 1 . 
     
     
         5 . A chamber ( 10 ) in accordance with  claim 1 , characterized in that a further liquid (D) is able to be supplied by means of a supply port ( 28 ). 
     
     
         6 . A chamber ( 10 ) in accordance with  claim 1 , characterized in that the further liquid (D) can be supplied continuously or can be supplied at predefined time intervals; and/or in that the filter element ( 26 ) includes a hydrophobic filter membrane or is formed by it. 
     
     
         7 . A chamber (/ 10 ) in accordance with  claim 3 , characterized in that the supply port ( 28 ) has a check valve ( 30 ) and/or a means preventing backflow ( 30 ). 
     
     
         8 . A chamber ( 10 ) in accordance with  claim 1 , characterized in that the chamber ( 10 ) has an infusion port ( 22 ) and/or has a screen means ( 40 ) in front of the blood outlet ( 24 ). 
     
     
         9 . A chamber ( 10 ) in accordance with  claim 1 , characterized in that the chamber ( 10 ) has a substantially cylindrical base body and the chamber ( 10 ) is formed eccentrically and/or in a flared manner in its upper end such that the blood entering into the chamber ( 10 ) via the blood inlet ( 22 ) can be dripped onto an oblique wall ( 14 ) formed thereby, with the blood inlet ( 22 ) being arranged eccentrically and parallel to the center axis of the chamber ( 10 ) so that the blood can be supplied to the chamber ( 10 ) in an off-center manner; and/or in that the outlet opening ( 23 ) of the blood inlet ( 22 ) is located beneath the blood level (S) adopted in the chamber ( 10 ) in operation. 
     
     
         10 . A chamber ( 10 ) in accordance with  claim 3 , characterized in that the outlet of the supply port ( 28 ) is arranged directly next to the filter element ( 26 ) at the head side. 
     
     
         11 . A chamber in accordance with  claim 1 , characterized in that the chamber ( 10 ) is a venous drip chamber ( 10 ) of a blood hose system, in particular of a blood hose system for dialysis. 
     
     
         12 . A chamber ( 10 ) in accordance with  claim 1 , characterized in that the liquid (D) which can be supplied via the supply port ( 28 ) is a filtered and pyrogen-free liquid, in particular a pyrogen-free and filtered dialysate and/or is a saline solution. 
     
     
         13 . A blood hose system having at least one chamber ( 10 ) in accordance with  claim 1 . 
     
     
         14 . A blood treatment system for the reception of at least one chamber ( 10 ) in accordance with  claim 1 . 
     
     
         15 . A blood treatment system in accordance with  claim 14 , characterized in that the blood treatment system is a dialysis machine; and in that the liquid (D) which can be supplied via the supply port ( 28 ) is a filtered and pyrogen-free dialysate which is provided and/or treated by the dialysis machine.
