1. A system for providing an indication of pain of a person such as measuring pain or a surrogate of pain symptoms of a person, said system for use with the tissue of the person, said system comprising:
A light source adapted for illuminating the tissue of the person; An optical sensor adapted for sensing light emitted or reflected by the tissue of the person, said optical sensor generating a light signal indicative of a light parameter of the sensed light; A surface electrode adapted for sensing an electrical parameter of the tissue of the person, said surface electrode generating an electrode signal indicative of an electrical parameter of the sensed electrical parameter; A temperature sensor adapted for sensing a temperature of the tissue of the person, said temperature sensor generating a temperature signal indicative of the sensed temperature; One or more circuits adapted for receiving the light signal, the electrode signal, and the temperature signal and providing corresponding signals; A controller adapted for receiving and processing the corresponding signals and adapted for providing a pain indication signal which is a function of the corresponding signals; An indicator adapted to be responsive to the controller for providing an indication which is indicative of the pain indication signal; and A power supply for supplying power to the system. |
