Method and device for monitoring health of respiratory system

Abstract

The invention discloses a respiratory system health monitoring method and device, the device comprises a processing system, an analysis terminal and a plurality of voltage change type detection elements, the processing system comprises a signal amplifier, a low-pass filter and an A / D converter, and the voltage change type detection elements, the signal amplifier, the low-pass filter, the A / D converter and the analysis terminal are connected in sequence. The pressure change type detection element generates an electric signal, and the processing system processes the electric signal and outputs a chest breathing oscillogram and an abdominal breathing oscillogram; and the analysis terminal calculates the respiratory rate and the respiratory energy, and judges whether the patient has a high respiratory risk, a medium respiratory risk or a low respiratory risk according to a calculation result. According to the method, the respiratory rate and the respiratory energy of the patient are calculated, and the evaluation index of the respiratory risk is formulated, so that the patients with medium and high respiratory risks can be distinguished, the patients can be treated and prevented, and the situation that the illness state of the patients suddenly deteriorates and cannot be found and treated in time is prevented.

Description

technical field [0001] The invention belongs to the technical field of respiratory system monitoring, in particular to a respiratory system health monitoring method and device. Background technique [0002] Respiratory diseases are a major public health problem facing the world, characterized by high morbidity, high disability, and high mortality. According to statistics, the number of deaths caused by chronic respiratory diseases (COPD) in the world exceeds 3 million every year, and more than 235 million people suffer from asthma. Respiratory monitoring technology is an important part of modern medical monitoring technology, and has important guiding significance for clinical medicine and nursing. The most commonly used respiratory monitoring equipment is a ventilator with respiratory support, which is the most common in the intensive care unit (ICU), but because of its high price and complicated operation, the number of hospital equipment is often limited. During the epi...

Problems solved by technology

[0006] The above detection equipment can collect the patient's respiratory data and transmit the data to the terminal device, but it does not disclose how to process the respiratory data. Generally speaking, these devices use conventional methods to process the data, such as judging whether the respiratory frequency is In the normal range, or a simple summary of the respiratory waveform, there is no further analysis of the data and a graded assessment of the respiratory risk. It is impossible to judge patients with high respiratory risk, and it is impossible to make some rescue preparations for patients with high respiratory risk in advance. Work
