Brain-computer interface based doctor-patient interaction method

Abstract

The invention provides a brain-computer interface based doctor-patient interaction method, which adopts a brain-computer interface based doctor-patient interaction system comprising an electroencephalographic collection module and an electroencephalographic analysis and doctor-patient interaction module. The method comprises the following steps of: setting visual stimulation signals with different frequencies, displaying the signals on a display, and mapping into controls of four commands through different combined codes (00, 01, 10 and 11) of 0 and 1; collecting an electroencephalographic signal of a subject by an electrode in real time, sending into a computer after the signal is amplified; analyzing the electroencephalographic signal; and broadcasting a voice prompt corresponding to the identification result through a speaker, and displaying the result on the display. Therefore, medical staff can carry out corresponding rescue according to the display and voice. The brain state can be identified by the brain-computer interface technology, and external equipment is accurately driven in time, so that communication and control can be realized. Brain can be effectively excited to generate steady state visual evoked potential by visual stimulations in different frequencies, the electroencephalographic signal can be accurately identified under stimulations in different frequencies through signal calculation and processing functions of the computer, and real doctor-patient interaction can be realized in the result display and voice prompt mode.

Description

technical field [0001] The invention relates to the technical field of biomedical signal processing, in particular to a doctor-patient interaction method based on a brain-computer interface. Background technique [0002] ALS is a type of motor neuron disease in which patients gradually lose their ability to move, leading to respiratory failure. However, all this happened when they were sane and clear-headed, and they clearly watched the whole process of their gradual death. It is urgent to help these patients according to the existing scientific technology. Using the doctor-patient interaction system designed based on Brain-Computer Interface (BCI) technology can help the "gradually frozen" group effectively solve communication problems in life, improve their quality of life, and reduce the possibility of accidents . [0003] On the other hand, China's ICU construction and management guidelines point out: "China's third-level and qualified second-level hospitals should se...

Problems solved by technology

Traditionally, medical staff always put all their energy on saving patients' lives and monitoring their condition, ignoring patients' needs

At the same time, it is difficult for major hospitals to achieve the staffing ratio of intensive care units (2.5-3:1)

Therefore, in view of the problem of insufficient staffing, when patients need help, especially at night, it is difficult to get help in time, but even in the daytime, when the staffing is sufficient, medical staff cannot timely To understand the patient's thinking, and sometimes may get the opposite result
