Embodiment 1

[0045] This embodiment provides a method for obtaining pain evaluation indicators, such as figure 1 As shown, the method includes:

[0046] Step 101: Collect brain wave signals of the cerebral cortex of the subject, and perform preprocessing on the brain wave signals.

[0047] Specifically, the above step 101 specifically includes: collecting brain wave signals of the cerebral cortex of the subject to be tested, and performing noise reduction processing on the brain wave signals according to the preset cycle, so as to remove interference from electrooculogram signals and electromyography signals.

[0048] In this embodiment, the subjects' scalp EEG signals were collected through the Neuroscan128 lead system, using a 128-lead EEG cap with electrodes arranged in a 10-20 system, Ag / AgCl electrodes, and the system parameters were set as: unipolar lead, two lead The side earlobe is the reference electrode, the sampling rate is 1000HZ, a 1-100Hz bandpass filter is used, and a 50Hz ...

Embodiment 2

[0058] In combination with the first embodiment above, the second embodiment of the present invention provides another method for obtaining pain evaluation indicators, such as figure 2 As shown, the method includes:

[0059] Step 201: start the visual analogue scoring system, obtain the pain score value associated with the selection according to the subject's selection, and record the pain score value.

[0060] Wherein, the analog scoring system refers to a system for collecting the subjective pain degree of the subject, and the time for completing the collection can be set. In this embodiment, it is specifically 10s. The collection interface for collecting the subjective pain degree is as follows: image 3 As shown, a pain score can be set, and the subject selects a score that meets the pain degree, and records the score.

[0061] Step 202: collecting brain wave signals of the cerebral cortex of the subject to be tested, and performing preprocessing on the brain wave signal...

Embodiment 3

[0078] Embodiment 3 of the present invention provides a device for obtaining pain evaluation indicators, such as Figure 4 As shown, the device includes:

[0079] The collection module 401 is configured to collect brain wave signals of the cerebral cortex of the subject, and perform preprocessing on the collected brain wave signals.

[0080] The collection module 401 is specifically used to collect the brainwave signals of the cerebral cortex of the subject, and perform noise reduction processing on the brainwave signals according to the preset period, so as to remove the interference of the electrooculogram signal and the electromyography signal.

[0081] In this embodiment, the subjects' scalp EEG signals were collected through the Neuroscan128 lead system, using a 128-lead EEG cap with electrodes arranged in a 10-20 system, Ag / AgCl electrodes, and the system parameters were set as: unipolar lead, two lead The side earlobe is the reference electrode, the sampling rate is 10...

Abstract

The invention discloses a method, apparatus and device for obtaining pain feeling evaluation indexes. The method comprises the steps of acquiring brain wave signals of the cerebral cortex of a detected person and pre-processing the brain wave signals; extracting time domain brain wave signals from the preprocessed brain wave signals, obtaining frequency domain information from the time domain brain wave signals and analyzing and calculating energy values of the frequency domain information to obtain energy values of Alpha waves and using the energy values of the Alpha waves as the pain feeling evaluation indexes to be output. The apparatus comprises an acquiring module and a processing module. The device comprises the device. The method, apparatus and device for obtaining the pain feeling evaluation indexes performs subjective and objective dimensional comprehensive evaluation by providing continuously changing pain intensity perception, objective evaluation results can be obtained, and application and popularization are facilitated.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a method, device and equipment for obtaining pain evaluation indexes. Background technique [0002] Everyone learns to express pain through injury early in life. About 30% of adults in my country suffer from chronic pain. Long-term pain damage to nerve tissue and spinal cord plasticity mechanism will lead to the formation of complex regional pain syndrome or central pain, making ordinary pain very severe and difficult to treat, seriously affecting patients quality of life and work efficiency, and even lead to suicide in a small number of patients. Pain is a subjective perception, so there is currently no effective and accurate method or technology to objectively quantify pain in clinical practice. [0003] At present, commonly used methods include method 1: subjective evaluation of pain such as Visual Analog Scale (VAS), 0 is no pain, 100 is the highest pain value that is unbearab...
