Nerve intensive monitor system and method for realizing synchronous monitor of human multi-parameter signals

Abstract

A neurological intensive care system comprising a signal collection system, a PC system for processing and displaying collected signal and a method for realizing human body multi-parameter in-phase monitor, wherein the signal collection system comprising a TCD module provided with a signal collection module, an EEG / MP module, a sample keeping circuit for in-phase sampling signals outputted from various collection channels, an A / D converter and a S / H control module for generating A / D conversion control signal and sampling control signal ; the method including: A. setting sampling control signal S / H in-phase with same clock pulse. B. employing S / H signal to enable all the signal channels to conduct in-phase sampling on TCD signal, EEG and MP signal in a same sampling point. C. A / D converting on the in-phase sampled analog signal sampling point and cache outputting the obtained digital signals. D. processing and displaying the digital signals by PC system. The invention realizes an in-phase monitor of TCD, EEG and MP signals.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a neurocritical care system and a method for synchronously monitoring human body multi-parameter signals such as brain function and cerebral circulation. Background technique [0002] Severe neurological illness is a severe brain function and cerebral circulation disorder caused by different causes of various systems of the body (nervous, circulatory, respiratory, endocrine, digestive, etc.), and the patient has severe disturbance of consciousness, such as coma, decorticated state, status epilepticus and cerebral circulation arrest Wait. In the process of diagnosis and treatment of severe neurological diseases, it is very necessary and important to observe the brain function, cerebral circulation and vital signs of patients with severe neurological diseases over a long period of time, to monitor the development and changes of the disease, to evaluate the treatment effect, and to ...

AI Technical Summary

Problems solved by technology

[0003] At present, there are only synchronous monitors for EEG and vital signs in China, which have simple analysis functions and cannot perform synchronous monitoring of cerebral circulation. Synchronous EEG and vital signs monitors cannot provide comprehensive and valuable monitoring and diagnostic information to meet the needs of clinical neurocritical care
