The electrode cap comprises an electrode cap body, a protection device and a plurality of electrical stimulation and electroencephalogram collection assemblies; the electrode cap body is a hemispherical cap-shaped piece, and the protection device is arranged on the outer side of the bottom wall of the electrode cap body; the plurality of electrical stimulation and electroencephalogram collection assemblies are uniformly arranged in the longitude direction and the latitude direction, each electrical stimulation and electroencephalogram collection assembly comprises an annular power connection assembly and a contact assembly, and the annular power connection assemblies are electrically connected through wires; the annular power connection assembly comprises an annular electroencephalogram collection socket and an electrical stimulation electrode probe; and the contact assembly comprises a threaded electrifying part and a contact head which are electrically connected, the threaded electrifying part is installed in the annular electroencephalogram acquisition socket through threads and electrically connected with the annular electroencephalogram acquisition socket, the electrical stimulation electrode probe is inserted into the threaded electrifying part, and the contact head is used for abutting against the human brain.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an electrode cap integrating current stimulation and brain electricity collection. Background technique [0002] Transcranial direct current stimulation is a non-invasive technique to regulate the activity of cerebral cortex neurons. It uses a low and constant DC intensity (0.5-2mA), and the duration is generally 5-30min. In recent years, transcranial direct current stimulation has received a lot of research and application in the fields of neuroscience and neuropathology due to its low cost, strong portability, and outstanding regulatory effect. This paper introduces the physiological effects and implementation methods of transcranial direct current stimulation, and discusses the research status and development trend of transcranial direct current stimulation in the regulation of brain cognitive function from the aspects of learning and memory, attention, perception, e...

Problems solved by technology

Due to the difference in the shape of the head of different people, the degree of tightness between the electrodes on the electrode cap and the scalp in different parts is different, so that this structure cannot ensure that all the electrodes are in effective contact with the scalp, resulting in some electrodes. The measured resistance increases, and the data generated by the measurement is inaccurate
