20080221639 | Pain Relief Device - The Pain relief device used to relieve pain and promote faster healing in the bodies of humans and animals safely. A positive electrode touches the skin at the site of an injury and a negative electrode completely shielded with insulation is place on the skin at a spaced distance form the positive electrode. A low voltage direct current power source supplies a positive voltage to the positive electrode and a negative voltage to the negative electrode. Electrical stimulation occurs harmlessly, because the shielded negatively charged electrode or insulated pad, being an insulated sheet of aluminum foil produces an electric field in the body that is strong enough to cause a current to flow into the body at the site of the positive electrode. However, no current can flow at the site of the negative electrode because it is insulated and therefore no burns to the skin. | 09-11-2008 |
