Brain pressure non-invasive monitoring analysis system based on physiological signal characteristic parameters

Abstract

The invention provides a brain pressure non-invasive monitoring analysis system based on physiological signal characteristic parameters. According to the brain pressure non-invasive monitoring analysis system, relevance between brain pressure changes and various physiological signals and relevance of various characteristic parameters are utilized comprehensively, clinical detection accuracy of brain pressure non-invasive monitoring results is guaranteed very well, influence weighted values of corresponding characteristic parameter kinds can be adaptively adjusted and selected according to characteristic parameter kinds input at different time periods through a brain pressure non-invasive monitoring model in the monitoring process so as to obtain brain pressure non-invasive detection values by operation, and the problem that non-invasive monitoring completely fails due to the fact that some characteristic parameters are inconvenient to obtain is solved; even if skip and switchover of different kinds of characteristic parameters occur, the brain pressure non-invasive monitoring results which the system calculates and outputs can also well keep stationarity and continuity, long-time non-invasive monitoring on brain pressure is effectively achieved, and system detection balance and clinical universal applicability are enhanced.

Description

technical field [0001] The invention relates to the technical fields of biomedical signal processing technology and non-invasive medical system, in particular to a non-invasive monitoring and analysis system of cranial pressure based on physiological signal characteristic parameters. Background technique [0002] At present, craniocerebral pressure testing (monitoring) methods are mostly invasive methods, and the most clinically used methods are ventriculocentesis and lumbar puncture. Because they are invasive, professionals are required to operate them. The clinical application requirements are high, and clinical data requires professionals. Explanation. Among them, the ventriculocentesis method also has the risk of expensive monitoring and infection, and because of the need for craniotomy or perforation, the clinical application of departments is limited; the lumbar puncture method itself also has certain errors, and only a single moment of cranial puncture can be obtained...
