Device and method for monitoring hydrocephalus and encephaledema

Abstract

The invention relates to a device used for monitoring hydrocephalus and encephaledema. The device comprises a signal encoding generator, an emission electrode, a receiving electrode, a signal processing digital converter, an orthogonal regulator, a detector, a parameter assessment device, a resistance analyzer and an assessment instrument. The invention also relates to a method used for monitoring hydrocephalus and encephaledema, which comprises the following steps of: intruding into the lower part of the skull skin; emitting electromagnetic waves; carrying out amplification and filter processing on the received electromagnetic waves, and converting the electromagnetic waves into digital signals; carrying out orthogonalization processing on the digital signals; detecting synthetic signals and orthogonal signals of the electromagnetic waves; calculating the relative attenuation coefficients, the relative phase displacement, the transmission speed difference and the complex wave value K; calculating the complex impedance Z and capacitance; and assessing hydrocephalus and encephaledema. According to the invention, hydrocephalus and encephaledema situations can be monitored and assessed all day in a non-intrusive mode so as to reduce the treatment risks.

Description

technical field [0001] The invention relates to a medical device and its usage method, in particular to a medical device for monitoring hydrocephalus and its monitoring method. 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 hy...
