Abstract:
A chamber is provided for a blood treatment system and has at least one space defined by a chamber wall, at least one blood inlet, and at least one inlet for a further fluid, which are connected with the space. Both the at least one blood inlet and the at least one inlet for the further fluid are formed on tube sections that protrude into the space of the chamber. In the operating condition of the chamber the space of the chamber is at least partly filled with blood or with a mixture of blood and either the further fluid or some other fluid. At least one, or preferably both, of the tube sections have a length such that the blood inlet and/or the inlet for the further fluid are located below the blood or fluid level in the chamber.

Claim (Index 9):
A method of using a venous drip chamber in a blood treatment system, wherein the venous drip chamber comprises:\n a chamber wall having a top; a space defined by the chamber wall; a circular lid connected to the chamber wall at the top of the chamber wall; at least one blood inlet; and at least one second inlet for a second fluid, wherein the at least one blood inlet and the at least one second inlet are connected with the at least one space, wherein both the at least one blood inlet and the at least one second inlet are formed on a first tube section and a second tube section, respectively, that protrude into the space of the chamber, wherein, in an operating condition of the chamber, the space of the chamber is at least partly filled up with blood or a mixture, the mixture comprising blood and either the second fluid or another fluid, wherein both the first tube section and the second tube section have a length such that the at least one blood inlet and the at least one second inlet are located below a blood level or a fluid level in the chamber, wherein the at least one blood inlet includes two blood inlets arranged on opposite sides of the first tube section and arranged so that an inflow of blood through the first tube section and into the space occurs in opposite respective directions, each of which directions lies between a radial direction and a tangential direction relative to the lid, wherein the at least one second inlet includes two second inlets arranged on opposite sides of the second tube section and arranged so that an inflow of second fluid through the second tube section and into the space occurs in opposite directions, each of which directions lies between a radial direction and a tangential direction relative to the lid, wherein the first tube section comprises a blood supply port and the second tube section comprises an infusion fluid supply port, wherein an extracorporeal blood circuit containing blood is connected to the blood supply port, and wherein a supply of infusion fluid is in fluid communication with the infusion fluid supply port, the method comprising: at least partly filling the space with the blood or with a mixture of the blood and the infusion fluid, up to a fluid level, to form an air cushion above the fluid level, wherein each of the first and second tube sections extends downwardly from the lid, through the air cushion, and below the fluid level in the space, and the two blood inlets and the two second inlets are located below the fluid level in the space.
