Embodiment 1

[0028] figure 1 It is a flow chart of the polarization voltage detection method in Embodiment 1 of the present invention. refer to figure 1 , a polarization voltage detection method according to Embodiment 1 of the present invention is proposed. The method comprises the steps of:

[0029] S1. Obtain the collected bioelectricity sampling signal.

[0030] For example, to obtain human ECG signals, obtain electrical signals from the human body through limb lead electrodes and chest lead electrodes. After analog amplification and analog filtering, analog-to-digital conversion is performed to obtain bioelectrical sampling signals. The electrode material of the limb lead electrode and the chest lead electrode is generally Ag-AgCl.

[0031] S2. Determine whether the first number of sampling points whose slope is greater than the first threshold is greater than M in consecutive T time periods; if yes, execute step S3.

[0032] The first quantity refers to the quantity of sampling ...

Embodiment 2

[0048] figure 2 It is a flow chart of the polarization voltage detection method in Embodiment 2 of the present invention. The polarization voltage detection method of this embodiment is as follows:

[0049] S1'. Obtain the collected bioelectricity sampling signal.

[0050] In this step, the signal collected in real time may be obtained, or the signal that has been stored may be obtained.

[0051] S2'. Determine whether the first number of sampling points whose slope is greater than the first threshold is greater than M in continuous T time; if so, execute step S2".

[0052]In this step, it includes calculating the slope first, then comparing it, performing statistics again, and finally making a judgment. For example, the slope can be calculated for each sampling point, then compared, and counted again. In this process, the next sampling point is also processed until the sampling point is processed within the continuous T time before making a judgment; The slopes of the sa...

Embodiment 3

[0062] image 3 It is a flow chart of the polarization voltage detection method according to the third embodiment of the present invention. refer to image 3 , propose the polarization voltage detection method of the third embodiment of the present invention, the method includes the following steps:

[0063] S10. Obtain the collected bioelectricity sampling signal.

[0064] S20. Divide the bioelectric sampling signal into several continuous detection units in time, and the time length of each detection unit is T.

[0065] In this step, the stored bioelectric sampling signal can be divided into several continuous inspection units according to the time length T; it can also be used as the detection unit to obtain the data within the time length T in real time, and when processing the current detection unit data, receive The data of the next detection unit can be processed in real time.

[0066] S21. Calculate a first number of sampling points with a slope greater than a firs...

Abstract

The invention relates to the field of bioelectricity signal detection, in particular to a polarizing voltage detecting method and equipment. The method comprises the following steps: A, obtaining gathered bioelectricity sampling signals; B, judging whether the first quantity of sampling points, of which the slope factor is larger than a first threshold value, within continuous T time is larger than M, executing step C if the first quantity is larger than M; and C, giving information indicating that the bioelectricity sampling signals have polarizing voltage. The method judges whether polarizing voltage exists by comparing the slope factor of the bioelectricity sampling signal to the first threshold value, and solves the technical problem that polarizing voltage can not be effectively judged in the prior art.

Description

technical field [0001] The invention relates to the field of bioelectric signal detection, in particular to a polarization voltage detection method and equipment. Background technique [0002] With the development of science and technology, bioelectrical signals generated by cell activities play an increasingly important role in clinical diagnostic applications. General bioelectrical signals include ECG, EMG, EEG, Oculoelectricity, Gastric Electricity and Neural Electricity, etc. Bioelectricity detection is a general term for a macroscopic technology that extracts bioelectrical signals from the human body or other organisms. When the body has a physiological response, the bioelectrical reaction occurs first, so the bioelectricity detection of different parts of the human body can record the reaction. The excitement changes in the corresponding parts, therefore, some lesions can be judged according to the bioelectrical signal, which is helpful for clinical diagnosis. Bioele...
