DEVICE FOR MEASURING AND ANALYSING THE COLOUR OF THE OUTER EAR AND EAR CANAL

摘要

The present application concerns a device for measurement and analysis of the middle ear and ear channel colour for the diagnosis of ear infections. The device is composed of a otoscope (1), including two optical fibers (2a and 2b) : one for ear illumination and another returning the reflected light. The electronic unit (3) can change linearly the power of emitted light, as well as, its colour. The received light is also independently measured, enabling the determination of changes on colour and texture associated with the ear inflammations. Command buttons in the otoscope handler (4) enable the user to save the values of the three colour components. The combined value of the components is shown in the digital display (5) of the electronic unit, as well as, by a set of LEDs (6) green, yellow and red that gives a diagnosis in a simple and immediate way. The otoscope allows, simultaneously, directly ear view through a magnifying glass (7) applied in the head of the otoscope, with a standard white light. This device is also useful in food industry.
