<p>A warning device (1) associable to a dental seat is adapted for warning an operator (2) of a patient's request.The device comprises a warning box (12) provided with one or more switches (14), the pressure of which lights a portion (14) provided with an icon representing the patient's request on a display (22), visible to the patient. Upon the patient's confirmation, for example automatically after a predetermined time interval, sound emission means emit, in a predetermined language, a signal that can be interpreted by the operator or a voice message corresponding to the patient's request.The device allows communicating the request to the operator without distracting or interrupting him/her and without making sudden movements, besides without having the need of speaking, which is often denied during dental operations.</p> |
