A wearable multi-channel wireless cortical electroencephalogram detection device

Abstract

The invention provides a wearable multi-channel wireless cortical electroencephalogram detection device comprising a multi-channel electroencephalogram recording electrode fixed to the head of a small animal, a waistcoat worn by the body of the small animal, a signal collector and a signal receiver, wherein the signal collector is connected to the waistcoat and connected to the electroencephalogram recording electrode. The signal collector comprises a shell, a collection module used for collecting electroencephalogram information recorded by the electroencephalogram recording electrode, an analog-digital conversion module connected with the collection module, a storage module connected with the analog-digital conversion module and used for storing information, and a radio frequency module connected with the analog-digital conversion module and the storage module and used for sending information sent by the analog-digital conversion module or the storage module to the signal receiver. The collection module, the analog-digital conversion module, the storage module and the radio frequency module are integrated on one chip and the chip is arranged on the shell; the size of the chip is less than 1cm<3>.

Description

technical field [0001] The invention relates to a wearable multi-channel wireless cortical electroencephalogram detection device. Background technique [0002] With the development of modern medical diagnostic technology, in recent years, people have begun to detect and study the bioelectrical activity (that is, event-related potential) generated by the thinking activities of the human brain. At present, small animals (usually mice) are commonly used as transgenes in research. animal models. Existing wireless cortical EEG detection devices have the following problems: [0003] ⑴The entire device is fixed on the skull of the small animal together, resulting in an open wound on the head of the animal that cannot be healed, and is prone to infection and death. For some research that needs to detect EEG at any time for a long time, these devices often cause the death of experimental animals, which increases the cost of experiments and the difficulty of research, and also viola...

AI Technical Summary

Problems solved by technology

[0003] ⑴The entire device is fixed together on the skull of small animals, resulting in an open wound on the head of the animal that cannot be healed, and is prone to infection and death

For some research that needs to detect EEG at any time for a long time, these devices often cause the death of experimental animals, which increases the cost of experiments and the difficulty of research, and also violates the ethical requirements of experimental animals;

[0004] ⑵The device is large in size and heavy in weight, so it is not suitable for small experimental animals such as mice, especially the small head of mice, so it is not suitable for installing large and heavy devices
