The present invention relates to a medical solution, a method for producing said medical solution, a multi-compartment bag containing the medical solution as well as use of said medical solution. According to the invention the medical solution comprises a first single solution comprising bicarbonate and carbonate in such proportions that the partial pressure of carbon dioxide, CO, in the first single solution is of the same order of magnitude as the partial pressure of carbon dioxide, CO, of the atmosphere. The medical solution further comprises a second single solution comprising an acid. Said first and second single solutions are, after terminal sterilization and up on use, to be mixed to form a final solution. Said second single solution has a pH of 1.0-1.5, and said final solution has a pH of 7.0-7.6.

Medical solution, a method for producing said medical solution and use thereof

The invention relates to measurement of a fluid flow, wherein a flow rate component of the fluid is measured along a selected direction. A magnetic field whose polarity varies over time is applied to the fluid, which presumed to contain electrically charged elements. First and second sensor electrodes () are arranged to be wetted by the flowing fluid. The electrodes () are spaced apart from one another along a line being substantially perpendicular both to the selected flow direction and a magnetic axis of the magnetic field. A DC-level drift of the sensor electrodes () is prevented by supplying a control current (I; I) to each of the sensor electrode (), which has such sign and magnitude that a direct-current voltage level at the sensor electrodes () relative areference potential is controled towards a predetermined voltage (DC).

Flow sensor and method for measuring a flow rate component of a fluid containing electrically charged elements

Apparatus for measuring fluid flow through a conduit including a measuring electrode and a ground electrode disposed in the conduit and connected to form an electrolytic cell, so that a voltage can be applied between the electrodes in order to cleanse deposits from the measuring electrode, and gases generated during the cleansing step can then be dissipated. Methods for measuring the fluid flow in such a manner are also described herein.
