Abstract
Abstract Electrostatic means radiating electrical energy at selected frequencies of the order of megacycles per second is safely and harmlessly coupled capacitively to tissue structure of a human being or of an animal with no significant flow of electrons for reducing sensitivity to pain, at least temporarily. The radiating means may comprise an evacuated glass envelope containing a selected atmosphere of inert gas and also containing an electrode that is intermittently subjected to an electropositive voltage during certain portions of the cycle to promote positive space charges within the envelope together with a controlled amount of ionization of said atmosphere and the production of selected forms of electromagnetic radiation such as infra red light, ultra violet light, visible light, and mixtures thereof.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
227 words
An electrostatic wand for the relief of pain upon contact with tissue structure comprising walls of electrically-insulating mAterial forming an enclosure having therein an elongate evacuated cavity, and an electrically-conducting member extending through said enclosure walls and having one end portion disposed within one end of said cavity and having a second end portion terminating externally of said walls and adapted to be connected to a source of electropositive electrical voltage pulses of the order of about 12,000 to about 15,000 volts and at variable frequencies in the range of about 300 to about 1,000 megacycles per second, said walls having a tissue-contacting external surface positioned opposite said one end of said cavity capacitively coupling said variable frequency pulses to ground potential when said surface is in contact with tissue structure, mirror surfaces within said cavity at opposite ends thereof and adjacent said conducting member and said external surface respectively, an annular member of electrically conducting material slidably disposed within said cavity for reciprocation therein, means electrically connecting said annular member to said conducting member, and means slidably mounted externally of said walls for reciprocation thereon and concomitantly selectively positioning said annular member, wherein said cavity is evacuated to a pressure of about 28 mm. of Hg. below atmospheric pressure and said cavity contains an inert gas at a pressure of about 1 mm. of Hg. absolute.
Claim 2
Dependent Claim
