Abstract

A method of and apparatus for the treatment of chronic wounds using pulsed electromagnetic energy provides a constant, known and replicable dosage output which remains unaffected by the capacitance of the patient's body. The apparatus is simple to operate, requiring little operator training or interaction with the apparatus. All specifications of the apparatus relating to the generation and emission of electromagnetic energy are fixed, with the specifications based on actual scientific studies of the various technical parameters involved, such as pulse width and RF dosage. The apparatus includes a pulsed electromagnetic energy generator, a power level controller and one or more thin applicators which can be flexible. The applicators are located immediately adjacent to the patient's body, without the aid of a support member or removal of any dressings or bandages. The generator, which can be battery-operated, is a low power, programmable compact unit whose output is controlled by multiple control circuits for ensuring accurate treatment dosage, for confirming that the treatment was properly administered, and for disabling the generator when appropriate. The generator output is automatically adjusted in response to instructions from the field strength sensor located on or near the applicator. Multiple applicators selected to operate simultaneously at different treatment dosage levels are connected to the generator by multi-conductor cables and readily located directly on the treatment area. Each applicator is a pad including etched printed circuits. The circuits are matched and pre-tuned. An applicator-to-patient proximity detector is also incorporated in or on each applicator and connected to the generator via a power controller to provide for direct monitoring of the treatment site and precise control of treatment dosage.
