AUSCULTATING SYSTEM AND METHOD USING BREATH ISSUED FROM MOUTH OR NASAL CAVITY

摘要

PURPOSE: An auscultating system and method using breath issued from mouth or nasal cavity is provided to reduce an erroneous diagnosis by using the auscultating system using sound of breathing. CONSTITUTION: A stethoscope(100) is formed with a main body, a mask for fixing a filter, a filter(130), a sensor(140), and an amplifier(150). The main body is formed with a hollow portion having a grating shape, a breathing sound guide portion installed at a front side of the hollow portion, and a cover installed at a rear side of the hollow portion. The filter(130) is installed at a front side of the breathing sound guide portion in order to filter alien substances issued from an oral cavity and a nasal cavity. The sensor(140) is used for sensing the sound of breathing passing through the filter(130). The amplifier(150) is used for amplifying a sense signal transferred from the sensor(140). A converter(200) is used for converting a signal transmitted from the amplifier(150) to an electric signal. A monitor(300) is used for displaying a waveform of an electrical signal transmitted from the converter(200). A speaker(400) outputs the sound transmitted from the amplifier(150).
