Radio emission device for monitoring hydrocephalus and cerebral edema

Abstract

A radio emission device for monitoring hydrocephalus and cerebral edema comprises a signal encoding generator and an emission electrode, wherein the signal encoding generator is used for generating preset electromagnetic waves and recording the initial amplitude and the initial phase of the electromagnetic waves, and the emission electrode is used for transmitting the electromagnetic waves generated by the signal encoding generator to a human brain. The device provided by the invention is located below the skin of human brain and sends preset electromagnetic waves, and then the preset electromagnetic waves are changed after going through the human brain. Specific circumstances of hydrocephalus and cerebral edema can be assessed by comparing the attenuation coefficients, relative phase shifts, time differences of transmission and complex wave values K before the electromagnetic waves enter the human brain and after the electromagnetic waves go through the human brain. Different from the traditional invasive monitoring method, the device provided by the invention can realize monitoring for 24 hours, and therefore, the medical security of hydrocephalus and cerebral edema can be notably enhanced.

Description

technical field [0001] The invention relates to a medical device, in particular to a medical device for monitoring hydrocephalus. Background technique [0002] A condition known as hydrocephalus is the excessive accumulation of cerebrospinal fluid (CSF) in the brain cavities, or ventricles. Under normal circumstances, cerebrospinal fluid is vital to the functioning of the brain. Transports nutrients and waste from the brain and creates a protective cushion of fluid. But an excessive buildup of cerebrospinal fluid puts disproportionate pressure on the brain and can lead to brain cell and tissue damage. Thus, medical conditions directly interrupt the absorption of CSF into the normal flow of blood and create CSF excess, which eventually leads to hydrocephalus. [0003] The potential and classification of hydrocephalus to affect people of all ages can be divided into two broad categories: congenital hydrocephalus and acquired hydrocephalus. Congenital hydrocephalus is the r...
