The invention relates to a degassing devive (25) for degassing blood, comprising a blood chamber (1, 1a, 1b) with a blood inlet (2) and a blood outlet (3), via which blood can be guided/is guided through the blood chamber (1, 1a, 1b), at least one underpressure chamber (11) with an underpressure attachment (8) via which the at least one underpressure chamber (11) is provided with an underpressure, at least one semipermeable membrane (4, 4a), which is arranged between the at least one underpressure chamber (11) and the blood chamber (1), wherein the blood chamber (1) comprises a first and a second sub-chamber (1a, 1b) which are arranged next to each other in a direction perpendicular to the direction of gravity, and a bridging region (9) which connects the two subchambers (1a, 1b) at their upper ends, wherein the blood inlet (2) is arranged in the lower region of the first subchamber (1a), and the blood outlet (3) is arranged in the lower region of the second subchamber (1b). The invention also relates to a system for extracorporeal treatment of blood.

A chamber body is provided, as regions where the liquid flows, with: an upper region including an area from the inner surface of the upper wall to the introduction pipe; a lower region connected to the outlet port; and a connection region connecting the upper region and the lower region. The inner circumferential surface of the upper region has a larger diameter than the inner circumferential surface of the lower region. As a result of diameter reduction from the connection portion relative to the upper region to the connection portion relative to the lower region, an inclined surface is formed on the inner circumferential surface of the connection region.

A device for establishing venous inflow to a blood reservoir of an extracorporeal blood circulation system includes a restricting unit for gradually closing a venous inflow line and a vacuum unit for supplying vacuum to the blood reservoir. The device includes a control unit that supplies a first actuating signal to the restricting unit for restricting venous inflow to the blood reservoir and supplies a second actuating signal to the vacuum unit for establishing a degree of vacuum within the blood reservoir.

An air trap chamber is provided with a cap and a housing. The cap has an inlet port provided at one end, and has, at another end, a first connection flange provided so as to have an inner circumferential surface. An opening axis of the inlet port is set so as to be off a center axis of the inner peripheral surface. The housing has, at one end, a second connection flange provided so as to have an outer circumferential surface which is mated to the inner circumferential surface, and has an outlet port provided at another end. An opening axis of the outlet port is set so as to be off the center axis of the outer circumferential surface. Moreover, parting lines which are positioning structures are provided on the cap and the housing, respectively.

A blood treatment device includes an extracorporeal blood circuit, a dialyzer and a dialysis fluid circuit. The extracorporeal blood circuit has an arterial portion, a venous portion, an air detector configured to monitor whether air is present in the venous portion, at least one blood pump configured to pump blood through the extracorporeal blood circuit, a venous hose clamp configured to selectively clamp or release the venous portion, a user interface, and a control unit. When the control unit receives information from the air detector that there is air in the venous portion, the control unit is configured to stop the blood pump, close the venous hose clamp, raise an alarm, and display on the user interface instructions for removing air in the venous portion and displaying status reports about the removal of air, and carry out automatic removal of air from the venous portion on a user-initiated basis.

This disclosure relates to dialysis systems and methods. In some implementations, a dialysis system includes a dialysis machine with a fluid line and a drain line, a blood line set configured to be connected to the dialysis machine, and a drain apparatus coupled to the dialysis machine. The drain apparatus includes a chamber configured to receive an end of a patient line of the blood line set, an inlet line, an outlet line, and a valve. The inlet line has a first end configured to be coupled to the chamber and a second end configured to be coupled to the fluid line of the dialysis machine. The outlet line has a first end configured to be coupled to the chamber and a second end configured to be coupled to the drain line of the dialysis machine. The valve is configured to control flow of fluid through the outlet line.

Dialyzer systems can consolidate multiple technologies and functionalities of blood treatment systems in a significantly integrated fashion. For example, this disclosure describes dialyzer systems that include a magnetically driven and magnetically levitating pump rotor integrated into the dialyzer. Such a dialyzer can be used with treatment modules that include a magnetic field-generating pump drive unit. In some embodiments, the dialyzers include pressure sensor chambers with flexible membranes with which corresponding pressure transducers of the treatment modules can interface to detect arterial and/or venous pressures.
