METHOD AND DEVICE FOR DETERMINING THE COMPOSITION OF MEDICAL LIQUIDS AS REGARDS THEIR PROPORTION OF ELECTROLYTES AND NON-ELECTROLYTES

摘要

The present invention relates to a method for determining the composition of medical liquids as regards their proportion of electrolytes and non- electrolytes, said method comprising the following steps: determining at least one first physical parameter of the medical liquid for unequivocal determination of the proportion of non-electrolytes in the medical liquid; simultaneously determining at least one second physical parameter of the medical liquid for determination of the proportion of electrolytes in the medical liquid; and determining the proportion of electrolytes and non- electrolytes in the medical liquid on the basis of the first and second physical parameters. The present invention further relates to a device for determining the composition of medical liquids as regards their proportion of electrolytes and non-electrolytes, said device comprising a first measuring device (7) for measuring a first physical parameter of the medical liquid that is in a defined ratio to the non-electrolyte in the medical liquid, a second measuring device (8) for determining at least one second physical parameter of the medical liquid that is in a ratio to the proportion of electrolytes in the medical liquid, and an evaluation device (9) for determining the proportion of electrolytes and non-electrolytes in the medical liquid on the basis of the measured values of the first measuring device (7) and of the second measuring device (8).
