Method and instrument for analyzing energy indexes of cerebral blood vessel

Abstract

The invention discloses a method and an instrument for analyzing the energy indexes of the cerebral blood vessel. The method comprises the steps of: detecting out the blood flow velocity wave form, the numerical value, the blood vessel diameter and the pressure waveform of carotid artery; detecting out the diastolic pressure and the systolic pressure of a human body to obtain the pressure waveform and the numerical value of the carotid artery; then calculating out the total potential energy, the stable potential energy, the oscillation potential energy, the total kinetic energy, the stable kinetic energy, the oscillation kinetic energy, the total energy, the stable total energy and the oscillation total energy of the cerebral blood vessel, and finally calculating out the ration of the oscillation total energy to the total energy, the ratio of the total kinetic energy to the total energy, the ratio of the oscillation potential energy to the total potential energy and the ratio of the oscillation kinetic energy to the total kinetic energy of the cerebral blood vessel. The detection analysis instrument comprises a detection system, a control system and a computation analysis system, wherein the control system can send an operation command to each detection module and can also transmit the acquired data information to a master industrial personal computer. A series of indexes of the cerebral circulation blood flow energy can be comprehensively analyzed with an invasive method, therefore, the invention has great importance for the basic research and clinical application of the cerebral circulation.

Description

[technical field] [0001] The invention relates to the analysis of cerebrovascular indexes in the field of medical technology, in particular to a method for analyzing energy indexes of the cerebrovascular system and a clinical analysis instrument designed according to the method. [Background technique] [0002] The basic function of the heart is to convert chemical energy into mechanical energy, and the blood is constantly converting kinetic energy and potential energy in the circulatory system, so it is possible to analyze the energy carried by blood in a specific circulatory system (such as systemic circulation, pulmonary circulation, etc.) To a certain extent, it reflects the condition of the vascular bed in the circulatory system. [0003] Hemodynamic energy indicators were originally used to evaluate cardiac function, because ventricular work can be divided into two categories: the ventricular external work done to promote blood movement, and the work done to overcome it...

Problems solved by technology

Then, they found that the Wt / CIs of biventricular circulation were 40% lower than that of single ventricle circulation, which indicated that in single ventricle circulation, a unit of forward blood flow needs to consume more energy, and its ventricular efficiency is relatively low

However, there are no related studies and reports on the analysis methods and instruments for energy indicators of the cerebral circulatory system.
