Digital amplitude-integrated cerebral function monitor

Abstract

The invention provides a digital amplitude-integrated cerebral function monitor (CFM). The CFM comprises a signal acquisition system, a signal amplification system and a signal processing system, and signals are acquired by the signal acquisition system, amplified by the signal amplification system and further processed by the signal processing system, thereby obtaining an amplitude-integrated electroencephalogram (aEEG), wherein, the signal acquisition system is a single-lead or double-lead system; the signal amplification system comprises an isolation amplifier and a main amplifier; and the signal processing system comprises a CFM filter module, an amplitude-squeezing module and a peak detecting and smoothing module. The digital amplitude-integrated CFM provided by the invention has the advantages of low environmental requirements and high anti-interference and anti-drifting performance, and can achieve the continuous bedside detection on a real-time basis for a long time and reflect the changes in the cerebral function of patients on a timely basis.

Description

technical field [0001] The invention relates to a digital amplitude-integrated brain function monitor, which belongs to the field of medical instruments. Background technique [0002] There are 18 million to 20 million live births in my country every year, among which, the incidence rate of perinatal asphyxia and hypoxia is 1.56%. About 300,000 children have brain damage caused by perinatal factors every year, resulting in nervous system disability. However, if early diagnosis and timely neuroprotective measures are taken, the occurrence of neuronal apoptosis can be controlled, thereby effectively reducing neuronal mortality. At the same time, with the improvement of obstetrical medical care in my country and the increase in the number of elderly mothers due to changes in lifestyle, the survival rate of premature infants has also increased from 4.5% in 1985 to 6% at present. Premature infants leave the mother's environment prematurely, and their nervous system is extremely ...

AI Technical Summary

Problems solved by technology

[0004] Using conventional EEG for brain function monitoring will encounter large variability in EEG waveforms, difficulty in interpreting neonatal EEG waveforms, many electrodes, complicated installation and disassembly operations, high environmental requirements, and is often used by other patients in the ward. Equipment or operation interference, the reliability of the signal cannot be guaranteed and other shortcomings, therefore, the conventional EEG system has not been widely used so far
