Abstract:
A device for monitoring the concentration of a chemical component within a patient's physiological fluid, comprising:(a) an electrode assembly for immersion within a patient's saliva, including: a ion selective electrode and a reference electrode for providing a voltage signal representative of the potential drop between said ion selective electrode and said reference electrode; and an interface element for electrically connecting said electrode assembly to a microprocessor;(b) a cup for accommodating a volume of a patient's saliva;(c) a stand element for holding said electrode assembly at a predetermined position with relation to said cup; and(d) a microprocessor for processing said voltage signal, said microprocessor determines the concentration of said chemical component within said volume of saliva according to said voltage signal and calculates the concentration of said chemical component within said physiological fluid according to a selected mathematical model.
