Embodiment 1

[0054]An embodiment of the present invention provides a method for assessing the degree of coma. Coma is a type of total loss of consciousness and is clinically critical. The occurrence of coma suggests that the patient's cerebral cortex function is seriously impaired. Medically, the degree of coma is divided into: mild coma, moderate coma, severe coma, and excessive coma. The embodiment of the present invention automatically evaluates the degree of coma of the coma patient by using the electroencephalogram signal of the coma patient, and performs prognosis judgment on the coma patient, thereby improving the accuracy and efficiency of coma degree evaluation.

[0055] Such as figure 1 As shown, the hardware system based on the embodiment of the present invention includes an EEG acquisition device and an evaluation terminal. The EEG acquisition device includes an acquisition module, an EEG data processing module, a data sending module and a power supply module. The power mod...

Embodiment 2

[0096] see Figure 5 , an embodiment of the present invention provides a device for evaluating the degree of coma, the device is used to implement the method for evaluating the degree of coma provided in the above-mentioned embodiment 1, the device includes:

[0097] Obtaining module 20, for obtaining the EEG data of comatose patients;

[0098] The preprocessing module 21 is used to preprocess the EEG data to obtain pure EEG signals;

[0099] The evaluation module 22 is configured to evaluate the degree of coma corresponding to the coma patient according to the pure EEG signal.

[0100] The assessment modules 22 described above include:

[0101] The calculation unit is used to calculate the coma sample entropy value corresponding to the coma patient according to the pure EEG signal;

[0102] The determination unit is configured to determine the coma threshold range where the entropy value of the coma sample is located; and determine the coma degree corresponding to the coma...

Abstract

The invention provides a method and device for evaluating the coma degree. The method comprises: electroencephalogram data of a patient is acquired; the electroencephalogram data is pretreated, and purified electroencephalogram signals are obtained; according to the purified electroencephalogram signals, the coma degree of the patient is evaluated. According to the method, the coma degree of the patient is automatically evaluated according to the purified electroencephalogram signals of the coma patient, manual intervention in the evaluating process of the coma degree is lowered, the influence of subjective factors of medical personnel on the evaluating process is avoided, man-made erroneous judgment is avoided, the evaluating error is reduced, and the evaluating accuracy is improved. Sample entropy is applied to evaluation of the coma degree, the sample entropy corresponding to the purified electroencephalogram signals is calculated, according to a threshold value range of the sample entropy, the coma degree is evaluated, quantification evaluation of the coma degree is achieved, and the evaluation efficiency is greatly improved. Meanwhile, according to the purified electroencephalogram signals, prognosis judgment is automatically conducted, the sample entropy is applied to the prognosis judgment of the coma patient, and the efficiency and accuracy of the prognosis judgment are improved.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a method and device for evaluating the degree of coma. Background technique [0002] Coma is a type of total loss of consciousness and is clinically critical. In order to shorten the patient's coma time and improve the survival rate of coma patients, it is necessary to determine the degree of coma, prognosis and current status of coma patients. [0003] Currently, the Glasgow Coma Scale is commonly used in medicine to assess the degree of coma in a patient. The assessment of the Glasgow Coma Index has three aspects: eye-opening response, language response, and body movement. The total score obtained by adding the assessment scores of these three aspects is the final coma index. However, medical staff conduct these three tests on patients by observing the patient's reaction to make judgments, so they are easily affected by the subjective factors of medical staff,...
