Embodiment Construction

[0024] Below, the present invention will be further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of not conflicting, the various embodiments described below or the technical features can be combined arbitrarily to form new embodiments. .

[0025] A method for collecting diaphragm electromyographic signals, which is used to collect diaphragm electromyographic signals that exclude electrocardiographic signals, comprising the steps of:

[0026] S1: Obtain the position of the diaphragm muscle electromyography signal containing the QRS complex through the detection method of the wavelet correlation coefficient;

[0027] S2: Process the signal at the position through threshold filtering;

[0028] S3: Obtain the processed diaphragm muscle electromyography signal through wavelet reconstruction.

[0029] A high-pass filtering step is also included before the S1 step, and the high-pass filtering...

Abstract

The invention discloses a method for collecting diaphragm myoelectric signals. The method used for collecting diaphragm myoelectric signals which are not interfered by electrocardiogram signals includes the steps of S1, using a detection method of a wavelet correlation coefficient to acquire a QRS wave group; S2, processing the acquired QRS wave group through threshold filtering; S3, using waveletreconstruction to obtain the processed diaphragm myoelectric signals. The method has the advantages that the interfering electrocardiogram signals can be eliminated thoroughly, and the useful diaphragm myoelectric signals can be well kept.

Description

technical field [0001] The present invention relates to the field of medical technology, in particular to a method for collecting electromyographic signals of diaphragm. Background technique [0002] The diaphragm is the main inspiratory muscle, and the electromyographic activity of the diaphragm can accurately reflect the drive of the respiratory center. Diaphragmatic myoelectricity (EGMdi) can be recorded by needle electrodes, esophageal electrodes and body surface electrodes. The advantage of using needle electrodes to record diaphragmatic EMG is that the electrodes are in direct contact with the diaphragm, and the degree of interference is small, which can accurately record the diaphragmatic EMG; the disadvantage is that the sampling range is small, and it is an invasive test, which is difficult to operate and easily damages organs. Complications such as hematoma and pneumothorax occur, so it is not suitable for clinical promotion. Studies have confirmed that the EMG o...
