Brain electrode cable interface device

Abstract

The invention relates to a brain electrode cable interface device. The device is formed by an interface and a terminal. All brain electrodes are gathered to the terminal. During usage, the terminal isplaced into a hollow cavity in the interface from an opening, and then a slide block is driven to move to an upper left portion in a map and enters into a lower slide slot from an upper slide slot soas to press the terminal so that a metal contact point is contacted with an elastic contact bar and electrical connection between the two is realized. When contact connection is required, the slide block is moved into the upper slide slot, and under the elastic force effect of the elastic contact bar, the terminal is jacked up, and then the terminal can be pulled out. The brain electrode cable interface device of the invention can be conveniently used and achieves the function of collecting the electrodes, and the phenomenon of disorder of existing brain electrode cables can be effectively solved.

Description

technical field [0001] The application belongs to the technical field of medical devices, and in particular relates to a brain electrode cable interface device. Background technique [0002] EEG is a graph obtained by amplifying and recording the spontaneous biopotential of the brain from the scalp through sophisticated electronic instruments. EEG needs to record the spontaneous and rhythmic electrical activity of brain cell groups through electrodes. Since the electrical activity of the whole brain needs to be recorded, a large number of brain electrodes need to be set up, such as Figure 5 As shown, it is the brain electrode placement map of the American Association for Electroencephalography. It can be seen that dozens of brain electrodes are needed, and each brain electrode needs a cable to connect with the electroencephalograph to transfer the electrical signals collected by the brain electrodes. Therefore, corresponding to dozens of brain electrodes, there are also doz...

Problems solved by technology

Since the electrical activity of the whole brain needs to be recorded, a large number of brain electrodes need to be set up, such as Figure 5 As shown, it is the brain electrode placement map of the American Association for Electroencephalography. It can be seen that dozens of brain electrodes are needed, and each brain electrode needs a cable to connect with the electroencephalograph to transfer the electrical signals collected by the brain electrodes. Therefore, corresponding to dozens of brain electrodes, there are also dozens of cables, so many cables are extremely easy to be entangled with each other, and the existing brain electrode cables are all plugged in one by one. It is very messy to plug into the EEG machine, and it is very inconvenient to unplug
