A disposable balancing unit designed as a sheet bag includes two sheets (1, 2), which are heat-sealed together, forming a balancing chamber (4) that is divided by a flexible wall (8) into the two chamber halves (9, 10), and forming two equalization chambers (5, 6), as well as the channels (15 through 18) connecting the individual chambers. The flexible wall (8), which separates the first chamber half (9) of the balancing chamber (4) from the second chamber half (10), is formed by an intermediate sheet, which is inserted between the first and second sheet (1, 2) in the area of the balancing volume and is heat-sealed in a pressure-tight manner to the outer sheets, forming the first and second chamber half (9, 10). The fixed volume of the balancing chamber halves (9, 10) is specified by a corresponding system insert unit, into which the disposable unit is fittingly inserted. The system insert unit has two rigid receiving bodies (25, 26) with trough-shaped depressions (27) to grasp above or below the balancing chamber (4) of the disposable unit. The disposable balancing unit can be manufactured cost-effectively in a single heat-sealing operation and is easy to handle.

[ What is claimed is:] [1.] A disposable balancing unit for balancing fluids for a medical treatment device comprising: first and second superposed plastic sheets, which are joined together in a pressure-resistant manner, forminga balancing chamber in the unit that is divided by a flexible wall into a first and a second chamber half, said flexible wall of said balancing chamber being formed by an intermediate sheet, which is inserted between the first and second sheet in the area of the balancing volume and is so joined to the first and second sheets, forming the two chamber halves so that said first chamber half is separated in a pressure-tight manner from said second chamber half;a first equalization chamber in the unit, which is in fluid communication with the first chamber half via a first inlet channel and, which is able to be clamped off in a pressure-tight manner;a second equalization chamber in the unit, which is in fluid communication with the second chamber half via a second inlet channel, which is able to be clamped off in a pressure-tight manner; anda first outlet channel, which is able to be clamped off in a pressure-tight manner and is in fluid communication with said first chamber half, and a second outlet channel, which is able to be clamped off in a pressure-tight manner and is in fluid communication with said second chamber half.
