[Method for evaluating sputum viscosity].

Continuing a study on mucolytically and secretolytically effective drugs, a viscometrically energetic principle was designed for controlling both the virtual viscosity and the adhesion of sputum. The technique used is integral in character, an amount of 2 to 4 ml of inhomogeneous purulent and foam-free sputum being sufficient for the purpose. The data are shown in a curve the characteristic of which is a piecewise e-function giving separate descriptions of the virtual viscosity and the adhesive behaviour. The curves are used to record the progress of the therapy used. "Technique and device for measuring viscosity" was registered at the Amt für Erfindungs- und Patentwesen der DDR HA Rechtsschutz in 1984 (WP G 01 N/251 817 5) the authors being Scheuler, Fischer and Felgenhauer. Details are given in.
