FIELD: medical equipment. ^ SUBSTANCE: control unit is placed in mouth cavity and comprises a signal processing and transmission module electrically connected to a cursor position control box and at least two output contacts functioning as mouse buttons, enclosed in elastic moisture-proof case and mounted on a clamping plate symmetrical relative to the longitudinal plane. The clamping plate consists of the centre, front and back bends. The latter is inclined upwards relative to the centre providing possibility to vary the inclination angle on bend lines. The front bend face is adjoined with a front clamping vessel. An intermediate clamping vessel is mounted on upper surface of the centre, while a back clamping vessel takes - upper surface of the back bend over the signal processing and transmission module. Each output contact is attached to lower surface of the centre of the clamping plate, while said position control box is fixed on lower surface of the back bend. ^ EFFECT: improved performance, simplified and low-price unit fabrication method. ^ 4 cl, 3 dwg |
