METHOD AND EQUIPMENT FOR MEASURING MOVEMENT OF SUBSTANCES/BOLUS IN A TUBULAR ORGAN

This patent application provides a method and equipment for promoting measurement of movement of substances/bolus in a tubular organ and for use in the impedance phase reading in the esophagus, thus integrating the field of exams performed for medical diagnoses, particularly for carrying out in the esophagus. The method is characterized by taking the difference between tension and current (impedance phase) as a parameter in the Impedance audiometry exam, from an excited element with alternate current; the proposed method uses a probe (5) defined by a flexible insulating catheter (1), including metallic rings (2) that is introduced in the organ (3) to be examined; the metallic rings (2) are connected by wires (4) that run internally through the probe (5) defined by the flexible insulating catheter (1); the probe (5) is connected to an equipment (6) that applies an electric excitation to the metallic rings (2) which act as electrodes.
