Embodiment Construction

[0056] An application specific embodiment of the present invention:

[0057] 1. Functional requirements and parameter values

[0058] 1) Sampling and AD converting the output signal of the body surface respiratory muscle electromyography measurement circuit, for example: the precision is 12bit, and the sampling frequency is 4K / s.

[0059] 2) Perform fourth-order low-pass filtering (for example: the cut-off frequency is 600Hz) and power frequency notch (optional 50Hz and 60Hz) processing on the signal.

[0060] 3) High-pass filtering to filter out polarization voltage, artifacts and unstable components, for example: the cut-off frequency is 10Hz.

[0061] 4) Calculating the myoelectric envelope and forming a respiratory myoelectric marking signal.

[0062] 2. Filtering, envelope calculation and respiratory myoelectric marker signal generation algorithm

[0063] 2.1. Fourth-order low-pass filter and power frequency notch

[0064] Low-pass filtering and power frequency notch,...

Abstract

The invention discloses a method and device for treating the central sleep apnea. The method includes the following steps that: 1) the surface electromyographic signals of respiratory muscles are collected; 2) filtering is carried out, so that undesired components can be filtered out; 3) the envelope of the surface electromyographic signals is calculated; 4) respiratory muscle electric mark signals are generated; 5) the blood oxygen saturation of a patient is detected, and a blood oxygen saturation probe which clamps a finger can be adopted; and 6) if respiratory muscle electric mark signals have not been sampled for 10 consecutive seconds, and the blood oxygen saturation is reduced by more than 3%, in vitro pacing is performed on the respiratory muscles. The method and device for treating the central sleep apnea of the invention have the advantages of high accuracy, high effectiveness and good use effect.

Description

【Technical field】 [0001] The invention relates to the field of medical technology, in particular to a method and device for treating central sleep apnea. 【Background technique】 [0002] Central sleep apnea (CSA) is characterized by repeated interruptions of airflow during sleep due to impaired central drive function. Central apnea refers to apnea lasting ≥ 10 seconds without respiratory movement. Usually >5 occurrences per hour are considered abnormal. The CSA syndrome is defined by central apneas of more than five episodes per hour of sleep during sleep with symptoms associated with sleep fragmentation (frequent awakenings) and / or excessive daytime sleepiness. Central apnea can also occur in patients with obstructive apnea, so we should focus on distinguishing CSA, although there is no absolute standard on this issue, usually the research on CSA patients requires that more than 50% or even 80% of the symptoms should be central. CSA is usually not caused by a single fa...
