Device for checking type of cerebral edema

Abstract

The invention discloses a device for checking the type of cerebral edema, comprising a computer system, an excitation circuit 1, an excitation circuit 2 and an excitation circuit 3; the output ends of the excitation circuit 1, the excitation circuit 2 and the excitation circuit 3 are connected with the computer system; the input end of the detection circuit 1 is connected with the excitation circuit 1, and the output end is connected with the computer system; the input end of a detection circuit 2 is connected with the excitation circuit 2, and the output end is connected with the computer system. Information reflecting physiological and pathological state of cerebral edema tissues can be obtained according to the function of biological tissue cell membranes and the change of water contents in and out of the tissue cell membranes, thus providing information about cerebral edema, severity of cerebral edema and characteristics of the type of cerebral edema. The invention has the advantages of reasonable design, simple structure, small size, low production cost, accurate detected data and the like, the device of the invention can be utilized as a diagnosis and monitoring apparatus for detecting the type and level of cerebral edema.

Description

technical field [0001] The invention belongs to the technical field of biomedical medical devices, and in particular relates to an inspection device for cerebral edema in neurology and surgery. Background technique [0002] Intracerebral surgical diseases such as various craniocerebral trauma, brain tumor resection, cerebral ischemia, brain tumor, encephalitis, and high altitude cerebral edema have entered the top three common fatal lesions in terms of morbidity and mortality. These intracerebral surgical diseases are accompanied by symptoms of cerebral edema. According to the different pathogenesis and pathological changes of cerebral edema, it can be divided into two categories: extracellular edema mainly caused by blood vessels and intracellular edema mainly caused by cytotoxicity. Correctly distinguishing the types of cerebral edema is an important basis for doctors to grasp the patient's condition, determine the treatment plan, and use the correct medication and treatm...

AI Technical Summary

Problems solved by technology

But it has the defects of contact measurement, many installed electrodes and complex feature extraction.

[0007] Transcranial Doppler has created a new method for non-invasive study of cerebral circulation, but this equipment still has technical problems that cannot be detected early and quantitatively

[0008] Using brain impedance detection equipment to monitor cerebral edema has the advantages of simple method, easy operation and dynamic monitoring, but there are problems that electrodes need to be contacted and the skull has a barrier effect on the current
