Abstract: The invention relates to a solution for storing organs, preferably kidneys. To effectively prevent organ damage, the solution has a high sulfate content and a low chloride content. In particular, the solution comprises about Na.sup.+ (2-30 mM), K.sup.+ (70-130 mM), MgH(30-40 mM), Ce.sup.- (2-20 mM), SO.sub.4.sup.2- (80-95 mM) and raffinose (20-60 mM) at aph of about 7.4.

Abstract: In a device for providing a substituate to a device for removing toxic substances from the blood which employs volumetric balancing of the fluid, an equalization chamber (11, 20) communicates with first and second inlet lines (9, 18) respectively, of a balancing chamber (14). Moreover, a buffer chamber (23) communicates with the first and/or second outlet line (15, 22) of the balancing chamber (14). The volume prevailing in the buffer chamber (23) that communicates with the first or second outlet line (15 or 22) can be so varied that the volume expands when the second or first equalization chamber (20 or 11) is emptied, and is reduced when the second or first equalization chamber is filled. As a result, the discontinuous pulse is smoothed on the outlet side of the balancing chamber.

Abstract: 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.

Abstract: A method and a device for the selective elimination of plasma components from blood, by means of which the blood is diluted with a diluting material prior to separation of the plasma therefrom. The blood diluted in this manner is separated from its plasma components in a separation filter and the plasma components are exclusively processed and the recombined with the corpuscular blood components and freed of the diluting solution.

Abstract: An apparatus for clamping flexible tubing employs one or more plungers as clamps. The plungers are reciprocally moveable by means of a rotatable disk cam which has a cam path on one or both of the faces of the disk, the disk cam being mounted to rotate on a shaft of a stepping motor. The plungers may be used to clamp a single tube or a plurality of tubes.
