Abstract

Abstract Apparatus for stimulating acupuncture points by light radiation in the visible light range or in the infrared range for medical purposes. An advantage of the apparatus of the invention resides in utilizing a very economical source of stimulating radiation, the radiation of which may be easily modulated and accurately focused, which considerably increases the efficiency of stimulation. An electrically conductive contact for locating acupuncture points, mounted directly in or on a transparent cover of a luminescent chip of a light emitting diode makes the locating of acupuncture points easy and accurate.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 112 words
An apparatus for stimulating acupuncture points on the skin of a living subject by light radiation and for detecting acupuncture points on the skin of a living subject by evaluating variations in skin impedance, comprising a light emitting diode and a surface electrode, said surface electrode being mounted on the surface of the light emitting diode for contact with the skin of the subject, a source of electric current for feeding the light emitting diode, circuit means for electrically connecting the light emitting diode with the source of electric current, and indicator means for evaluating variations in the impedance of skin of the subject at the location engaged by the suface electrode.
Claim 2
Independent Claim 112 words
An apparatus for stimulating acupuncture points on the skin of a living subject by light radiation and for detecting acupuncture points on the skin of a living subject by evaluating variations in skin impedance, comprising a light emitting diode and a surface electrode, said surface electrode being mounted on the surface of the light emitting diode for contact with the skin of the subject, a source of electric current for feeding the light emitting diode, circuit means for electrically connecting the light emitting diode with the source of electric current, and indicator means for evaluating variations in the impedance of skin of the subject at the location engaged by the suface electrode.
Claim 3
Dependent Claim 38 words
