Problems solved by technology

[0007] However, since the above-mentioned functional formula is a single relational formula established based on the data of sample patients, and does not consider the individual differences of the specific tested patients, its applicability to different patients and different diseases is poor, and it cannot meet the actual needs. application requirements

Embodiment Construction

[0068] In order to better explain the present invention and understand it better, the present invention will be further described below through specific embodiments in conjunction with the accompanying drawings.

[0069] see figure 1 and figure 2 , the invention provides a method for measuring non-invasive intracranial pressure, comprising the steps of:

[0070] (1) Establish a sample database containing sample data of n samples, the sample data includes intracranial pressure related data obtained by non-invasive testing and intracranial pressure actual measurement data obtained by invasive testing;

[0071] (2) Perform data analysis on the sample data of each of the samples, and establish a sample model that reflects the relationship between the intracranial pressure-related data and the measured intracranial pressure data;

[0072] (3) Selecting the sample model of the sample that is closest to the patient under test based on the intracranial pressure related data of the ...

Abstract

The invention relates to a noninvasive intracranial pressure measuring method and a noninvasive intracranial pressure analyzer using the method. An initial sample database is built with sample data of a sample patient serving as a sample, data training is carried out, a plurality of sample models are built, noninvasive measurement, analysis and processing are carried out on intracranial pressure relevant data of the patient to be tested, the sample model with the largest similarity to the patient to be tested is selected, and the measured intracranial pressure relevant data of the patient to be tested are substituted into the selected sample model to obtain noninvasive ICP data of the patient to be tested. According to the method and the analyzer, the sample models are built in advance, and the sample model with the smallest error is selected to serve as the sample model of the sample to be tested so as to predict noninvasive intracranial pressure. The method and the analyzer are suitable for different individuals and patients of different groups, are good in backward compatibility, can achieve quick and accurate measurement through simple computation according to the database after data training, and remarkably improve measurement speed and accuracy.

Description

technical field [0001] The invention relates to a non-invasive measurement method of intracranial pressure, which is mainly used for non-invasive measurement of intracranial pressure in neurology, neurosurgery, and intensive care unit (ICU). The invention also relates to a non-invasive intracranial pressure measurement method using the measurement method. pressure analyzer. Background technique [0002] Since the flash visually evoked signal is very weak (0.3-20 μv), it is easily submerged in the EEG signal and other external signals (the EEG signal is 30-100 μv), and multiple measurements are required to obtain the average value. The patient brings fatigue and discomfort, and it is also easy to introduce explosive artifacts, especially for critically ill patients, the scope of application of this method is limited to a certain extent. And based on the flash visual evoked potential method, it is usually assumed that there is a fixed functional relationship between the intra...
