Non-invasive brain death detection and evaluation instrument

Abstract

The invention relates to a non-invasive brain death detection and evaluation instrument. The technical scheme is as follows: the non-invasive brain death detection and evaluation instrument comprisesan optical signal acquisition system, a control and data transmission system, and a data analysis and brain death evaluation system, wherein the optical signal acquisition system sends near infrared light to the brain of a patient and collects a response signal, and transmits the response signal to the control and data transmission system; the control and data transmission system controls the optical signal acquisition system, and integrates the collected data and transmits the integrated data to the data analysis and brain death evaluation system; the data analysis and brain death evaluationsystem comprehensively analyzes a human body optical signal transmitted by the optical signal acquisition system, and displays the obtained result. The non-invasive brain death detection and evaluation instrument is reasonable in design, the function of optical detection for brain death in a non-invasive, completely non-invasive, real-time and continuous detection and portable manner for 48 hoursor a longer time is realized, meanwhile, the brain metabolism data can be provided in real time, an imaging system is used for dynamic display, so that the evaluation result is more visual, and the use is more convenient.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a non-invasive brain death detection and evaluation instrument. Background technique [0002] Brain death means the end of human life and is defined as the permanent loss of brain and brainstem function. Clinical symptoms are generally due to increased intracranial pressure, when the intracranial pressure exceeds the patient's systolic blood pressure, it will lead to cerebral circulation stop. Assessment of brain death has important implications, for example, organ transplantation relies heavily on organs from brain-dead patients, which account for more than 22% of total organ donations in many countries. In addition, due to limited medical resources, it is meaningless to rescue brain-dead patients, which can only increase the suffering and economic burden of patients and their families. The international criteria for determining brain death on a neurological basis incl...
