Substance intolerance testing by measuring patients response to electric stimulation at characteristic frequencies of that substance

摘要

An intolerance testing device and an intolerance testing system for determining a person's intolerance of specific substances, primarily specific foodstuffs. The device includes a memory for storing data which represents a signature frequency that is characteristic of a number of substances. The device includes a stimulation electrode for applying an alternating stimulation voltage signal, derived from the memory, at a selected frequency, to a user's skin. An amplifying and filtering circuit is coupled to a sensing electrode to detect a change in sensed body voltage. The device may comprise a wrist-watch like housing 10 with a display 15 and two pairs of skin contact electrodes on the inside of the wrist band 10b, stimulation electrodes 12a,b and measurement electrodes 14a,b.
