Embodiment Construction

[0060] In the following, the present invention will be further described in conjunction with specific implementation methods. It should be noted that, on the premise of not conflicting, the various embodiments or technical features described below can be combined arbitrarily to form new embodiments.

[0061] An application specific embodiment of the present invention:

[0062] 1. Functional requirements and parameter values

[0063] 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.

[0064] 2) Perform fourth-order low-pass filtering (for example: cut-off frequency is 600Hz) and power frequency notch (optional 50Hz and 60Hz) processing on the signal.

[0065] 3) High-pass filtering to filter out polarization voltage, artifacts and unstable components, for example: the cut-off frequency is 10Hz.

[0066] 4) Calculating the myoelect...

Abstract

The invention discloses a method and device for treating central sleep apnea. The method comprises the following steps of 1) collecting surface electromyographic signals of respiratory muscles; 2) filtering by a filter; 3) performing envelope calculation on the surface electromyography signals; 4) generating electric mark signals of the respiratory muscles; 5), detecting blood oxygen saturation ofa patient by using a blood oxygen saturation probe clamped to a finger; 6), if the electric mark signals are not sampled in 10 seconds and the blood oxygen saturation drops by 3% or above, conductingexternal pacing on the respiratory muscles. The method is applied to the device. The method and device have the advantages of being accurate and effective, and the use effect is good.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a method and a 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 a central apnea of ​​more than 5 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 fact...
