摘要: 本实用新型公开了一种多通道肺音成像装置,包括多路肺音传感器、放大电路、A/D转换器、低通滤波器、数据采集单元、数字信号处理单元、闪速存储器、控制单元、供电单元、计算机,所述多路肺音传感器的信号输出接入到放大电路;放大电路输出的信号接入到A/D转换器;A/D转换器输出的信号接入到低通滤波器;低通滤波器输出的信号接入到数据采集单元的输入端进行信号采集;数字信号处理单元对闪速存储器数据进行处理;数字信号处理单元输出的信号接到控制单元输入端;控制单元输出端与计算机连接。本实用新型能够直观显示肺部不同部位呼吸时产生的声音特征;从而克服了医生主观的影响,并且能够显示人耳无法听到的低频声音信号,弥补听觉可能导致的误诊。
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.
