| Abstract: | This paper presents a KNY ventilating function detection apparatus of eustachian tube based on the theory that the eustachian tube will be opened passively and the pressure of meatus acusticus externus be changed with the increase of nasopharynx pressure.The apparatus can detect the actual pressure of nasoparynx and meatus acusticus externus,and acquire the pressure value when the eustachian tube is opened passively.Finally,the results can also be output by way of microcomputer. |
