Phlegm sound distinguishing method

Abstract

The invention provides a phlegm sound distinguishing method, and belongs to the field of medical instruments. The phlegm sound distinguishing method comprises the specific steps of preparing phlegm sound distinguishing equipment, distinguishing and identifying phlegm sound, recording phlegm sound distinguishing data and comparing and analyzing the phlegm sound data. According to the method, the condition of phlegm sound can be judged in time, corresponding processing actions can be executed, the error rate is reduced, the treatment rate of patients is improved, automatic detection and control functions can be realized, audio signals of patients are collected in real time at the connecting interface of a trachea cannula or a laryngeal mask and a breathing pipeline through a sound pickup, and the analyzed audio signals are compared with the standard pronunciation of the phlegm sound in real time; and if the audio signals are in the range of the standard pronunciation of the phlegm sound, a phlegm sound distinguishing information processing host performs automatic phlegm suction, and otherwise, the phlegm sound distinguishing information processing host continues to collect the audio information, so that the operation is more stable, and the misjudgment rate is reduced. The method can solve the problem that whether phlegm is sucked is manually judged by periodically using an echometer through medical staff, and accurate and timely response cannot be realized.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a method for discriminating phlegm sounds. Background technique [0002] Generally, phlegm sounds are produced by viscous secretions in the main trachea. It is a special kind of moist rales, which can be heard in both inhalation and exhalation, but mainly inhalation, which can be transmitted to both lungs. , so it can be heard in both lungs (not really produced by the lungs), once the secretions are excreted or sucked out, the sputum sound weakens or disappears. [0003] There is no uniform standard in the existing technology: there is no accurate standard for judging the sound of phlegm, and it is still passed on by word of mouth through the master and the apprentice. Different doctors or different hospitals have different judgments on phlegm sounds. [0004] However, the existing identification methods have the problems of untimely identification, non-standard identif...

AI Technical Summary

Problems solved by technology

[0004] However, the existing identification methods have the problems that the identification is not timely, the identification is not standard, and the medical staff periodically use a stethoscope to manually determine whether to suck sputum, which cannot achieve accurate and timely response.
