Iontophoresis device
First Claim
1. An iontophoresis device comprising:
- a) a first array comprising one or more electrodes;
b) a second array comprising one or more electrodes;
c) a direct current source connected to the first and second arrays;
d) a first reservoir for containing a first liquid into which the first array is substantially submerged; and
e) a second reservoir for containing a second liquid into which the second array is substantially submerged;
such that when the direct current source is applied to either the first or second arrays, charged particles in either the first or second liquids are conducted through the skin of a patient who has submerged a body part in the first reservoir and a body part in the second reservoir.

Abstract
A device for iontophoresis. A first battery-powered array is submerged into a liquid contained in a first reservoir and a second battery-powered array is submerged into a liquid contained in a second reservoir. Each array has one or more degradable electrodes that releases ions into the liquid in the reservoir. The electrodes can be copper, zinc, steel, nickel, or a combination thereof. At the first array one of the electrodes can be positively charged while at the second array one of the electrodes can be negatively charged. Alternatively, an electrode at the second array can be positively charged while an electrode at the first array is negatively charged. The solution in the reservoir may also contain positively or negatively charged ions. Powering the arrays causes the charged molecules contained in the liquid to transport through a patient'"'"'s skin. The device uses a current and voltage regulator to deliver a regulated amount of current through the arrays regardless of the conductivity of the liquid, and electronic circuitry is used to control the duration, polarity, electrode choice, and intensity of the treatment. Excessive heat is dissipated with a heat sink.
