Breathing frequency collecting method for oxygen uptake monitoring and breathing frequency collecting device for oxygen uptake monitoring

Abstract

The invention provides a breathing frequency collecting method for oxygen uptake monitoring and a breathing frequency collecting device for oxygen uptake monitoring. The method comprises the followingsteps of 1, collecting breathing sound data of the mouth and / or the nose, and transmitting the breathing sound data of the mouth and / or nose to a controller; 2, collecting environment sound data of the mouth and / or the nose, and transmitting the environment sound data of the mouth and / or the nose to the controller; and 3, eliminating data with the same waveform as the environment sound data of the mouth and / or the nose from the breathing sound data of the mouth and / or the nose through cross comparison, thereby obtaining the practical breathing sound data of the mouth and / or the nose. The breathing sound data and the environment sound data are used for comparison denoising; then, the precise breathing sound data can be obtained through the analysis and comparison by the controller; and thebreathing frequency data can be further obtained.

Description

technical field [0001] The invention relates to the technical field of oxygen therapy monitoring equipment, in particular to a breathing frequency acquisition method and device for monitoring oxygen inhalation. Background technique [0002] The main purpose of oxygen therapy is to correct the hypoxemia of the human body, reduce the work of breathing and reduce the load on the heart, prevent and reverse the tissue damage and organ dysfunction caused by hypoxia, and at the same time maintain the patient's mobility as much as possible. The main risk of oxygen therapy is that it cannot effectively correct hypoxemia, aggravate carbon dioxide retention, and even oxygen toxicity. The principle of standardized oxygen therapy is to ensure its safety and effectiveness. There are two well-known international controlled clinical trials that can clearly prove the effectiveness of home oxygen therapy and the corresponding conditions, and it is also the scientific basis for many countries...

AI Technical Summary

Problems solved by technology

[0008] This solution has the following deficiencies: 1. Because the pressure change signal caused by respiration is weak, the sensor needs to be selected to meet the high-precision requirements; 2. Because the sampling calculation amount is relatively large, and the device requires energy saving and power saving, the main control single-chip microcomputer (MCPU) Or the selection requirements of DSP processors are high; 3. The above factors 1 and 2 will lead to increased costs, which is not conducive to popularization and application
