Patent ID: 7477947

Claim:
A system for electrically detecting a lack of saliva in an oral cavity of an individual and for electrically stimulating the oral cavity, so as to induce production of saliva from at least one salivary gland, said system comprising: a control device for detecting a measure of salivation in the individual and for delivering electrical impulses to the oral cavity of the individual, said control device having at least one pair of electrodes provide a contact with a tissue of the oral cavity; a check device for obtaining the data of said measure of salivation and for modifying at least one parameter of said control device, and a computer device for exchanging information with said check device; wherein said measure of salivation is a relaxation time, said relaxation time being a measure of time required for a voltage difference between said at least one pair of electrodes to reach a predetermined level of an initial value of said voltage difference after a measuring pulse is applied.
