The examinee lies on his back with his knees bent and the abdomen fully exposed. The working height of the bed plate lifted is 80 cm. The abdominal sounds are collected nine times, and divided into upper abdomen, middle abdomen (umbilicus region) and lower abdomen according to the abdominal nine-minute method; the left mondinal region (splenic region), the left lumbar region, the left iliac region; right mondinal region (hepatic region), right lumbar region, right ilium. The abdominal sounds are collected from top to bottom and from left to right. The inspector can regulate and control the inspection process through the console.

As for abdominal sounds, there are mainly: bowel sound, vascular noise (artery/vein), fricative sound, and water vibration sound.

The abdominal sounds are collected from top to bottom and from left to right in sequence; with regard to the above description of the embodiment:

the abdominal sound amplifying circuit and the complex sound filtering circuit can be realized by a miniature integrated circuit. The abdominal sound amplifying circuit is mainly used for amplifying abdominal sounds. The abdominal sound filter circuit is mainly used for filtering out noise and interference sound of the environment and making the abdominal sound clear. If the wired or wireless connection circuit adopts a wired connection mode, a plug can be connected with a jack of an earphone of the intelligent terminal, and the intelligent terminal provides power. If the wireless connection intelligent terminal is adopted, various connection modes can be provided. For example: and the intelligent terminal is connected with the Bluetooth, the near field communication and the like. The power supply circuit is a battery-powered circuit or a circuit composed of a stabilized voltage power supply.

The specific implementation of the method for effectively collecting and judging the abdominal sounds transmitted from the circuit box, namely collecting, processing and training the abdominal sound data, is as follows:

the collected abdominal sounds are subjected to data preprocessing, including digital filtering, aiming at filtering high-frequency noise and direct-current noise and simultaneously preserving the abdominal sound signals as much as possible, and the specific mode is that audio is sent into a second-order 25-400hz Butterworth median filter, and abdominal sound data are visualized so as to be displayed in a report. Code implementation examples are given:

from scipy import signal

def band_pass_filter(original_signal,order,fc1,fc2,fs):

median filter

Param order filter order

Params fs audio sampling rate

Param fc1 cut-off frequency

Param fc2 cut-off frequency

Param original _ signal which is abdominal sound data

Return filtered audio data

”'

b,a＝signal.butter(N＝order,Wn＝[2*fc1/fs,2*fc2/fs],btype＝'bandpass')

new_signal＝signal.lfilter(b,a,original_signal)

return new_signal

audio_data＝band_pass_filter(audio_data,2,25,400,fs)

plot_signal(audio_data,title＝'After Filter')

To reduce the computational load of the model, a samplerate package is invoked to downsample all audio signals, considering that we have median filtered the audio by 25-400HZ, we downsample the signal to 1000HZ according to the nyquist sampling theorem

import samplerate

# Down sampling

down_sample_audio_data＝samplerate.resample(audio_data.T,1000/fs,converter_type＝'sinc_best').T

plot_signal(down_sample_audio_data,title＝'Down_sampled')。

Due to the large file differences in the different antinode data, we normalize all the antinode signals, i.e. partition all the antinode data in the range of [ -1,1 ]. The antinoise data is then visualized for presentation in the report.

To utilize as much of the existing abdominal tone data set as possible, a longer abdominal tone cutting process is required. For example, the abdominal sounds may be cut in units of 2.5 s.

Before model training, the fusion of the abdominal sound data sets is carried out, the fusion of the data sets can be carried out according to diagnosis requirements on abdominal sounds, and the abdominal sound diagnosis method is divided into two different data sets:

the data set comprises all normal abdominal sounds and abnormal abdominal sounds;

the data set II only contains four types of abnormal abdominal sounds of AS, MS, MR and MVP;

the second-order spectrum analysis method is adopted for extracting the features of the data, and the method can keep useful features in the signal as much as possible and reduce noise in the process of feature extraction.

The second order spectral analysis can be represented by the following notations:

wherein the content of the first and second substances,in order to perform a second-order fourier transform,is the third order cumulant

Specific code implementation examples are given:

# feature extraction

from extract_bispectrum import polycoherence,plot_polycoherence

ex_audio_data＝down_sample_audio_data[:2500]

freq1,freq2,bi_spectrum＝polycoherence(

ex_audio_data,

nfft＝1024,

nperseg＝256,

noverlap＝100,

norm＝None)

bi_spectrum＝np.array(abs(bi_spectrum))#calculate bi_spectrum

bi_spectrum＝255*(bi_spectrum-np.min(bi_spectrum))/(np.max(bi_spectrum)-np.min(bi_spectrum))

plot_polycoherence(freq1,freq2,bi_spectrum)

# resizing to facilitate engagement with neural networks

bi_spectrum＝bi_spectrum.reshape((256,256,1))

An AOCT convolutional neural network is employed herein. Therefore, the classification task is completed, 4 volume blocks which take the volume layer, the BN layer and the activation function as a whole are used in the network, and the result is transmitted into the full-connection layer to obtain the final result.

The invention can automatically collect and intelligently diagnose the abdominal sounds by designing the equipment which can automatically collect and intelligently diagnose the abdominal sounds, automatically collect and process data of the abdominal sounds, identify the abdominal sounds of patients, and simultaneously check corresponding frequencies, thereby intelligently diagnosing diseases. The intelligent device replaces the process that medical staff listen to abdominal sounds and diagnose by experience, and medical efficiency and diagnosis accuracy are improved. The invention is suitable for common users to use in families and offices, makes simple diagnosis, learns diseases in advance, reduces the workload of doctors and lightens the working pressure. The invention can send a digital medical advice report to the intelligent terminal of a doctor and a medical advice report to the intelligent terminal of a user, and can control the printer to print, thereby being convenient for reading and understanding. After deep learning based on the database, the method can identify weak noise which is easy to ignore in artificial auscultation, and reduce the probability of missed diagnosis and misjudgment. The system of the invention can store the data of the patient and construct the database to realize the deep learning and data sharing of the system while processing the data in real time and diagnosing the abdominal sound condition of the examinee.
