This device is formed by a number of semi-rings and their extensions, adapted for fitting to the human head of a patient and for exerting pressure on predetermined parts of said head, comprising a principal open crown (12) configured in the shape of a “U” formed by a slightly concave back zone (13), which extends in two side zones (14-15) converging inwards, and whose extremities or sidepieces (16-6′) have on the inside thereof cavities (19-19′) adapted for housing contact elements (17-17′), wherein the front surface is perceptibly warped convexly, partly projecting inwards inside the crown (12). The extremities or sidepieces (16-6′) have in upper portion thereof cavities (18-18′) directed inwards with a certain inclination with respect to the plane of the principal crown (12) adapted for housing the ends of a second open crown (11).
