Problems solved by technology

[0004] Traditional intracranial pressure detection needs to punch a hole in the skull, which will bring some pain to the patient in clinical application, and this will damage the skull and cannot be repeated, and the later infection of the skull wound can directly lead to the death of the patient ,

Abstract

The invention discloses an intracranial pressure non-invasive measuring method. The method includes the following steps that step one, at least two ultrasonic sensors with a same specification are utilized to obtain a normal ultrasonic amplitude value and a phase reference signal; and step two, the ultrasonic sensors are arranged at temple positions of two sides of a head to be measured respectively, an incentive ultrasonic signal parameter which is same to that of the step one is utilized, the signal collected by the ultrasonic sensors is processed again and then transmitted to a computer, and an additional pressure value, namely an intracranial pressure can be detected by a differential demodulation method. Beside, the invention further discloses a system for intracranial pressure non-invasive measuring. By means of the intracranial pressure non-invasive measuring method and the system, the sensors are not required to be extended to the interior of a measured object (the head), and the ultrasonic wave is harmless to human body, so that a nondestructive ultrasonic testing for the measured object (the head) can be achieved, and the defect that the non-invasive testing for the measured object (the head) can not be achieved in terms of existing detection devices is overcome.

Description

technical field [0001] The invention relates to the technical field of signal measurement and analysis, in particular to a non-invasive measurement method for intracranial pressure, and also to a measurement system. Background technique [0002] As a non-destructive testing method, ultrasonic technology is widely used in life medicine, food analysis, quality control, material science and geophysics. Objects will deform when subjected to force, and because the mass of the object is constant, the density of the object will change accordingly. The propagation characteristics of ultrasonic waves in an object are related to the material, density, hardness, temperature and other parameters of the object. When only the density of the object is considered, the relationship between the force on the object and the wavelength and phase of the ultrasonic wave can be obtained. Using this theory The relationship between intracranial pressure and ultrasonic wavelength can be obtained. U...
