A device and method for non-invasive intracranial pressure monitoring

Abstract

The invention relates to the technical field of intracranial pressure monitoring, and specifically discloses a device for non-invasive intracranial pressure monitoring, including a detection module, a signal processing module, and an analysis module; the signal connection between the detection module, the signal processing module and the analysis module; The signal processing module is used to generate excitation signals; the detection module includes several transmission electrodes; the transmission electrodes are used to receive the excitation signals and output the excitation signals to the intracranial; the signal processing module is also used to receive the excitation signals passing through the intracranial from the transmission electrodes, and The excitation signal is used as the signal to be processed and amplified and processed to obtain a digital signal; the analysis module extracts the actual parameters based on the digital signal, and judges whether the intracranial pressure is normal based on the actual parameters and the pre-stored characteristic parameters. If it is not normal, the analysis module outputs Early warning information. Adopting the technical scheme of the invention can facilitate accurate monitoring of the intracranial pressure at the bedside.

Description

technical field [0001] The invention relates to the technical field of intracranial pressure monitoring, in particular to a non-invasive intracranial pressure monitoring device and method. Background technique [0002] Intracranial pressure (ICP) refers to the pressure generated by the contents of the cranial cavity on the wall of the cranial cavity, also known as brain pressure. Since the cerebrospinal fluid exists in the subarachnoid space and the brain cistern, it is between the wall of the cranial cavity and the brain tissue, and communicates with the subarachnoid space in the ventricle and spinal cord cavity, so the hydrostatic pressure of the cerebrospinal fluid can represent the intracranial pressure, Usually represented by the CSF pressure in the lateral position. When the intracranial pressure continues to be above 2.0kPa, corresponding symptoms and signs are caused, which is called increased intracranial pressure. The reasons for increased intracranial pressure a...

AI Technical Summary

Problems solved by technology

The above two methods are invasive, expensive, will increase trauma, and there are risks of various complications, such as hemorrhage, intracranial infection, etc., and require high technical requirements for medical staff performing monitoring

In addition, intracranial pressure monitoring can also be diagnosed through CT, MRI and other imaging equipment, but these two examinations need to be arranged in a separate consulting room, which is time-consuming and expensive, and it is not possible to perform the examination at the bedside, nor can it be implemented Dynamic continuous monitoring

[0004] The above-mentioned monitoring method leads to complicated monitoring steps of intracranial pressure and high requirements for operating medical personnel.

If the patient needs to monitor the intracranial pressure, it takes a long time to prepare, and it cannot be measured at any time, so it is impossible to accurately monitor the intracranial pressure at any time.
