DETECTION OF GUM USING OPTICAL DETECTOR IN ORAL HYGIENE DETECTION DEVICE

摘要

FIELD: physics.;SUBSTANCE: detection device (1000) allows to detect a substance (116) that may be present on the surface (31, 33), on the basis of the stream probe signal measurement, correlating with the substance (116) at least partially preventing the passage of fluid (30, 35) through the stream probe (500). The device includes a distal section (620) of the optical gum detector transmission and a distal section (720) of the optical gum detector reception in the position for transmission and for reception, respectively, of the optical signal under the control of the controller (2251), allowing the controller (2251) to determine whether the open port (526) of the distal end (522) of the stream probe (500) contacts with the substance (116) at least partially preventing the passage of fluid (30, 35) through the open port (526), and whether it contacts with the gums of the subject or the user of the detection device (1000) to ignore the false positive signals.;EFFECT: device improvement.;28 cl, 46 dwg
