Abstract
A power supply provides direct current to electrodes attached to a patient. The positive electrode is at least partially silver and releases silver ions as a result of the electric current. Silver ions have known bactericidal properties and may be used to treat infected living tissue. Tissue may, however, be damaged by voltages in excess of 1.1 volts. Accordingly, the power supply has two modes. Under normal conditions the power supply has a constant current output. If the voltage between the electrodes reaches a reference voltage of not more than 1.1 volt, the output is changed to a constant voltage mode, abruptly limiting the output voltage. A mode indicator may be incorporated in the supply.
