Description

Trinity hat intelligent monitoring and early warning system

technical field

The utility model relates to the field of monitoring and wearable intelligent equipment. More specifically, the utility model relates to a three-in-one cap-type intelligent monitoring and early warning system.

Background technique

Mild hepatic encephalopathy (MHE) is characterized by hidden nerves and movement disorders, and it is easy to develop into clinical hepatic encephalopathy. Although it is the mildest form of hepatic encephalopathy, the onset is often outside the medical institution. Out of the monitoring environment, transient movement disorders are likely to cause falls, trauma and traffic accidents, so early diagnosis and intervention are particularly important. Existing studies are mainly based on subjective methods and passive assessment of behavioral diagnosis. There are passive subjective factors, and the monitoring starts after the patient has developed a serious hysteresis. It has almost no practical significance for the prevention of accidental injuries. Based on this, There is an urgent need to implement objective assessment and preventive active monitoring on the target population, so as to facilitate early detection and timely treatment, so as to reduce the probability of disease and disability in patients with liver disease.

The human brain, especially the cortical cells, has frequent spontaneous electrical activities without any external stimulation. Brain electrodes can record the response potential of a large number of neuron activities in the brain, down to the microvolt level, and the fluctuation of the potential of this electrical activity with time becomes an electroencephalogram (Electroencephalograph, EEG). The current monitoring of hepatic encephalopathy is mainly routine EEG monitoring, followed by analysis of abnormal signals, which is a non-specific hysteresis monitoring. In fact, during the onset of hepatic encephalopathy, the damage of the cerebral cortex and the change of brain metabolism lead to functional potential changes and form characteristic waveforms. The electrical activity of this pathological brain tissue and the functional state of the special brain can be identified theoretically in EEG. Although a large amount of brain electrophysiological evidence shows that there are significant changes in the brain structure and function of MHE patients, most studies only use the differences in waveforms of brain structural parameters (such as volume, etc.) and functional parameters (such as functional connectivity, etc.) The results of detection require professional monitoring and interpretation by professionals, and the availability is poor; while routine detection will ignore the spatial distribution of these abnormalities and the connection between abnormal characteristic electrical signals and clinical manifestations.

On the basis of previous research and pre-experiment, the utility model finds that patients with hepatic encephalopathy have characteristic encephalopathy waves, and the characteristic EEG monitoring and its prediction model can provide potential objective information for MHE, so the characteristic EEG of MHE can be objectively This characteristic waveform is captured through dynamic monitoring before the onset of hepatic encephalopathy, which plays the role of early warning and detection.

The existing EEG acquisition method is to use electrodes installed on the scalp to draw out the electrical activity of the cells and record it after being amplified by the EEG machine. The scalp electrodes need to be fixed by special devices and operated by trained professionals. Utility model patent CN201320486784 discloses an EEG acquisition device, which is mainly designed for a new type of suction cup magnetic electrode, but the measurement method adopted is still the traditional scalp electrode method, which is inconvenient to use and requires the use of a special EEG Image acquisition device.

In addition, most of the existing EEG monitoring uses professional testing, and the results are interpreted by professional doctors. Even some mobile medical devices require professional interpretation, which is not suitable for daily monitoring.
