英文摘要 | The utility model discloses a multi-channel lung sound imaging device. The multi-channel lung sound imaging device comprises a multi-path lung sound sensor, an amplifying circuit, an A/D (analog/digital) converter, a low-pass filter, a data acquisition unit, a digital signal processing unit, a flash memory, a control unit, a power supply unit and a computer, wherein the signal output of the multi-path lung sound sensor is accessed to the amplifying circuit the signal output from the amplifying circuit is accessed to the A/D converter the signal output from the A/D converter is accessed to the low-pass filter the signal output from the low-pass filter is accessed to the input end of the data acquisition unit for signal acquisition the digital signal processing unit is used for processing the data of the flash memory the signal output from the digital signal processing unit is accessed to the input end of the control unit and the output end of the control unit is connected with the computer. According to the imaging device, the sound characteristics of different parts of the lung when breathing are displayed visually, so that the influence of subjective judgment of a doctor is overcome and furthermore low frequency sound signals which people cannot hear can be displayed, thereby compensating misdiagnose caused bythe hearing. |
