Embodiment

[0035] Such as figure 1 Shown is a schematic diagram of the present invention. Among them, the multi-channel physiological measurement device collects signals from fixed electrodes in the heart, impedance signals from body surface excitation electrodes, electric field positioning signals from body surface ECG electrodes, and other data sources including respiratory signals. The multi-channel dynamic monitoring device monitors the quality of multi-channel signal acquisition in real time, and automatically distinguishes valid channels from abnormal channels. The alarm device alarms the abnormal channel in the dynamic monitoring and prompts to adjust the abnormal electrode. The respiratory index extracting device extracts the respiratory signal from the effective communication signal obtained through dynamic monitoring and calculates the respiratory index through normalization processing. The display is used to display the final respiratory index.

Abstract

The invention relates to the field of medical machinery, in particular to a respiratory index extraction system and working method based on multi-channel dynamic monitoring. Including body surface excitation electrodes, body surface ECG electrodes, body surface reference electrodes, intracardiac catheters, multi-channel electrophysiological measuring devices, and computer systems, characterized in that: the body surface excitation electrodes, body surface ECG electrodes and body surface The reference electrodes are all connected to the multi-channel physiological measurement device, and the multi-channel physiological measurement device is also provided with two intracardiac catheters, the intracardiac catheters are inserted into the heart, and the multi-channel physiological measurement device is connected to the computer system. Compared with the prior art, the present invention can dynamically monitor multi-channel signals containing breathing, feed back and update the data source channel of respiratory index in real time, and obtain respiratory index with better signal-to-noise ratio; Respiratory status, monitor electrode affixation status during operation, improve the positioning accuracy of interventional surgical instruments and the clarity of medical three-dimensional imaging.

Description

technical field [0001] The invention relates to the field of medical machinery, in particular to a respiratory index extraction system and working method based on multi-channel dynamic monitoring. Background technique [0002] Atrial fibrillation (Atrial Fibrillation) is the most common cardiac arrhythmia clinically, with prevalence estimates ranging from 1% of the general population to 17% of the 80-year-old population. Patients with atrial fibrillation account for approximately one-third of hospitalizations for arrhythmias, and the incidence increases with age. In 2010, China defined atrial fibrillation as the loss of normal and orderly electrical activity in the atrium, which is replaced by a rapidly disordered tremor wave, which is the most serious obstacle to atrial activity. With the aging of the population and the increase in the incidence of cardiovascular diseases, atrial fibrillation has become a public health safety problem with high complications, which seriousl...
