Abstract

Abstract An electrotherapeutic treatment head is disclosed for use with a drive circuit which applies pulses of electrotherapeutic energy to the treatment head. The head includes a hollow housing in which is mounted a spiral coil, the coil being flat in the plane of the spiral. Connected to the coil is an adjustable capacitor, one plate of the capacitor being connected to one of the outer loops of the spiral-shaped coil while the other plate thereof is connected to one of the inner loops. The capacitor and coil together form a tank circuit. Also disposed in the housing is a primary coil which is directly connected to the drive circuitry and which inductively couples the pulsed energy to the spiral-shaped coil, from whence it is radiated to an appropriate load such as a patient. The primary coil consists of a single loop and is flat in the plane of the loop and parallel to the spiral-shaped coil. Also disclosed are various modifications of the spiral-shaped coil, the primary coil, and means for mounting the primary and spiral-shaped coils within the housing.
