An automatic device for treating the scalp, comprising:
- a fixed portion, in turn comprising:
- a casing;
- a first direct current electricity generator, activatable to generate a direct current and arranged in the casing;
- a second voltage generator, which is arranged in the casing and which is activatable to generate a current having a biphasic rectangular or triangular waveform, having a frequency comprised between 2.0 and 3.0 Hz;
- a handle electrically connected to the first direct current electricity generator and to the second voltage generator and, in turn, comprising:
- a body;
- a motor having a drive shaft, both arranged in the body with the motor being arranged proximally and with the drive shaft being arranged distally and longitudinally with respect to the body, a motion transmission element which is solidly constrained to a distal end of the drive shaft and which has a motion transmission surface which is distal and which is inclined, with respect to the drive shaft, by a minimum angle comprised between 5° and 85°, the motor being electrically activatable to move the motion transmission surface in rotation with respect to the drive shaft;
- a first electrical contact;
- a second electrical contact;
- at least a lighting device, activatable to emit a coherent non-collimated monochromatic electromagnetic radiation;
- and
- an operating head comprising:
- a first plurality of rounded protuberances made of an electrically conductive material, a second plurality of rounded protuberances made of an electrically conductive material, a third electrical contact, electrically connected to the first plurality of protuberances;
- a fourth electrical contact electrically connected to the second plurality of rounded protuberances;
- a piston-cylinder system, in turn comprising, a tubular element which functions as a cylinder of the piston-cylinder system and which has a distal end;
- a piston which:
- has a rod and a head having an distal end, wherein the piston is slidably inserted in the tubular element with freedom to move from a first limit position, wherein the distal end of the head is arranged externally of the tubular element and at a first distance, measured parallel to the rod, from a distal end of the tubular element, to a second limit position, wherein the distal end of the head is arranged at a second distance, measured parallel to the rod, from the distal end of the tubular element, that is less than the first distance;
- or wherein the distal end of the head is arranged internally of the tubular element;
- and elastic means acting on the head and predisposed to automatically move the piston from the first limit position to the second limit position;
- wherein the first and second plurality of rounded protuberances are solidly constrained to the distal end of the operating head and project distally there from;
- wherein the at least a lighting device is solidly constrained to the handle and arranged distally or is solidly constrained to the operating head and distally arranged;
- wherein the tubular element is solidly and reversibly fixable to the handle in such a way that the operating head is at least partially internal of the body of the handle and supported by the handle electrically connecting the first electrical contact to the third electrical contact and the second electrical contact to the fourth contact, arranging the rod offset, but substantially parallel to the drive shaft, and in contact with the motion transmission surface and arranging the distal end of the head externally of the handle, when in the first limit position, and wherein the at least a lighting device, the motor, the first generator, and the second voltage generator, are activatable contemporaneously.
