Cardiac and pulmonary impedance measuring method and device

Abstract

A cardiac and pulmonary impedance measuring method and device is disclosed. The method is characterized by including: entering basic information of a patient, and using the device to acquire a cardiac impedance analog signal and a pulmonary impedance analog signal of the patient; allowing an analog-digital conversion module to convert the acquired cardiac and pulmonary impedance signals into cardiac and pulmonary impedance digital signals, and filtering and denoising the digital signals; extracting feature values from the digital signals; building neural network models, entering the basic information and the extracted feature values into neural networks, training the neural networks, and determining weight values of the neural networks; classifying the trained models according to the entered feature values, and outputting corresponding health states. The cardiac and pulmonary impedance measuring method and device has the advantages that according to two types of basic information of the patient and five features extracted from the cardiac an pulmonary impedance signals, the cardiac and pulmonary health states of the patient are primarily detected, detecting is simple and fast and accurate, hospital resources are well saved, expenditure on seeing doctors is decreased for the patient, and the device is simple in structure, easy to manufacture, low in cost and convenient to use.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a method and device for measuring cardiopulmonary impedance. Background technique [0002] The lungs and the heart are two organs that are crucial to human health. Once the lung function or heart pumping function is impaired, it will have a serious impact on people's normal life and even life. On the other hand, these two organs are related to each other, and when one of them is diseased, the other will also be more or less affected. For example, cor pulmonale, although it is a heart disease, is caused by lesions in the bronchi or lung tissue. Clinically, it will show both heart failure and pulmonary failure and other signs. Human being is an organic whole of a system, and lung and heart are two extremely important parts, there must be interaction, even a lesion will be reflected in the function of both organs. [0003] At present, the examination of heart disease is based on ...

Problems solved by technology

However, the device does not collect sign information for heart and lung functions, but only body temperature, pulse and blood pressure, so it cannot get good analysis results in terms of the health status of the lungs and heart
