Electrode device for measuring scalp and skull impedance in animal experiments

Abstract

The invention discloses an electrode device for measuring scalp and skull impedance in animal experiments, and belongs to the technical field of impedance measurement.Split structures of an electrode cap, an electrode core and an electrode outer barrel are integrated into a whole, the electrode core is arranged in the electrode outer barrel, the upper portion of the electrode outer barrel is sleeved with the electrode cap, the wiring way in an electrode is simplified, and elements in a scalp electrode circuit and a skull electrode circuit are tightly combined, so that influences of external disturbance on measurement results are reduced, scalp measurement and skull measurement can be achieved, disassembly, assembly and cleaning work are convenient due to the split structures, and measurement accuracy can be effectively ensured; in addition, a spring is arranged between a skull electrode pad layer and the electrode cap, the height of the skull electrode pad layer can be adjusted through the spring, it can be ensured that the skull electrode pad layer is connected with the electrode core, and it is ensured that the skull electrode makes direct and tight contact with the electrode pad layer.The electrode device is easy and convenient to use and easy to operate, and provides a reliable guarantee for smoothly carrying out animal experiments.

Description

technical field [0001] The invention belongs to the technical field of electrical impedance measurement, and in particular relates to an electrode device for measuring scalp and skull of electrical impedance in animal experiments. Background technique [0002] Different human tissues have different cell structures, so different human tissues have different electrical impedances. In normal tissue under pathological conditions, its cell structure will also change. Therefore, the same tissue also has different electrical impedances under normal physiological and pathological conditions. Under normal circumstances, by placing electrodes on the surface of the human body, applying a safe excitation current to the human body, and then measuring the electrical impedance of the measured part, the normal physiological and pathological state of the human body can be judged, and then it can be used for the detection of human organ function and the prevention and treatment of diseases. ...

Problems solved by technology

However, detecting the distribution of current in the skull is a routine experiment to verify electrical impedance measurement technology, so we need electrodes that can penetrate deep into the skull, and cup electrodes cannot meet the requirements
