Device for the local treatment of a patient, and more particularly applicable in acupuncture and auriculotheraphy

A device for point-treatment of a patient, comprising a treatment head, a power supply unit, and a flexible connection therebetween, at least one laser diode carried by said treatment head, said treatment head comprising a body of generally cylindrical form, which terminates in a truncated portion, said truncated portion carrying a short cylindrical portion of smaller diameter than the diameter of said cylindrical body, said short cylindrical portion having an interior surface for defining a treatment orifice for selectively receiving said laser diode and an exterior surface for defining a mounting surface for mounting a separate end piece for selectively receiving said laser diode, and laser control energizing means located within said treatment head for controlling the laser diode, so that said diode emits laser pulses of light, said supply unit including means for applying trains of electric pulses to said laser control energizing means recurrently and in a controlled manner, said energizing means comprising a capacitor and a thyristor arranged in series circuit relationship with said laser diode, said supply unit including means connected across the capacitor and capable of charging the same, while electric pulses are applied to the control gate of said thyristor, the power supply unit including means for furnishing the laser diode with two different D.C. voltages, the lower voltage serving for detection purposes without considerable laser stimulation, the stronger voltage serving for the treatment with laser pulses, the power supply unit including means for switching a frequency parameter of said electric pulses, cyclically among a predetermined plurality of frequency values, and wherein the treatment head carries a first manual switch means for controlling energization of said laser diode, said treatment head also carrying a second manual switch means for controlling said cyclic switching of the frequency parameter, said means for switching a frequency parameter including a first generator in the supply unit, the basic recurrence frequency of the first generator being switchable among a plurality of selected frequencies, including means for adjusting the frequency parameter, step by step correction control means in said supply unit for effecting said adjustment of the frequency parameter, and wherein said treatment head includes a third manual switch means for actuating said step by step correction control means.
