Electromagnetic wave signal processing device

Abstract

An embodiment of the invention discloses an electromagnetic wave signal processing device. The electromagnetic wave signal processing device comprises a fixing device, a controller, a frequency converter and a noise reducer, at least four electrode plates electrically connected with the controller are arranged on the inner side of the fixing device, and each electrode plate is electrically connected with any one attribute end of a receiving end, a transmission end and a grounding end by the controller. The frequency converter controls the transmission end to transmit electromagnetic wave signals of different frequencies into skull by the electrode plates, two of the electrode plates electrically connected with the receiving end receive the electromagnetic wave signals and the noise reducer is used for reducing noise of the electromagnetic wave signals.

Description

technical field [0001] The invention relates to the technical field of signal monitoring, in particular to an electromagnetic wave signal processing device. Background technique [0002] Cerebral edema refers to the pathological phenomenon of increased water in the brain, which is the response of brain tissue to various pathogenic factors. Cerebral edema can easily lead to intracranial hypertension and severely damage brain tissue. Clinically, it is common in neurological diseases, such as internal skull trauma, intracranial infection (encephalitis, meningitis, etc.), cerebrovascular disease, and intracranial space-occupying diseases (such as Tumor), seizures and systemic diseases such as toxic dysentery, severe pneumonia, etc. Therefore, timely and accurate diagnosis of cerebral edema, mastering the changes of cerebral edema, and correct treatment of cerebral edema are one of the key factors for the successful treatment of brain diseases such as acute cerebral circulation ...

AI Technical Summary

Problems solved by technology

[0003] At present, the examination methods for patients with cerebral edema mainly include direct measurement of intracranial pressure, computer tomography (CT, Computer Tomography) and magnetic resonance imaging (MRI, Magnetic Resonance Imaging). Among them, direct measurement of intracranial pressure is an indirect reflection Methods for the degree of cerebral edema include lumbar puncture manometry and epidural manometry. However, the direct measurement method of intracranial pressure needs to place a pressure sensor in the body, which is traumatic and likely to cause pain to the patient. guardianship

At the same time, it is impossible to determine the location and size of cerebral edema with this method, therefore, direct measurement of intracranial pressure needs to be combined with CT or MRI techniques

[0004] Although the use of CT detection and MRI technology solves the problem of determining the location and size of brain edema, it takes a certain amount of time for the shape change of brain edema, and CT and MRI cannot monitor in real time, so the situation of brain edema cannot be discovered and monitored in the first place

In addition, CT and MRI examinations are time-consuming and expensive, and are not suitable for bedside monitoring.
