Aphasia patients can speak through their own brains. Brain-muscle interface, also known as BCI technology, has been used in the Department of Critical Care Medicine of the Second Affiliated Hospital of Jiaotong University and the School of Mechanical Engineering of Xi Jiaotong University. And applied in clinic. An aphasic patient with paraplegia sent his first short message recognized by brain waves by wearing an EEG cap. Hello. Most of this research has been used in the army before. In medical treatment and related EEG examination, BCI technology was first applied to critically ill patients in ICU. At the same time, it will also make better contributions to the good communication between patients, family members and medical staff. The patient can use his brain to control the machine and send out what he wants. There is still something to say, which is much better and safer than patients blinking to express their emotions.
(2) Invasive and non-invasive BCI have their own advantages and disadvantages.
BCI technology is also divided into invasive, BCI and non-invasive BCI. The signals of brain waves can be extracted from the cerebral cortex of patients by invasive implantation of chips, or directly through EEG caps by non-invasive methods, that is, patients need to wear certain EEG caps. Tools for transmitting information, brain wave signals, have advantages and disadvantages. The former is that you can receive more accurate brain signals. At the same time, it is convenient to reduce the unnecessary trouble of wearing EEG cap in the later stage. The advantage of the latter is that it does not need to cause secondary harm to the patient, and only needs to wear a hat to solve the aphasia problem of the patient.
(3) Aphasia patients can also pass brain waves? Talking "is very human.
At present, the technology is still in the preliminary research stage, and a clinical trial has been carried out on a high paraplegic patient. The name also achieved the expected effect. I believe that in the near future, this technology will be popularized to many critically ill patients, and it will also facilitate the clinical diagnosis of patients with high paraplegia or aphasia, and also increase a communication channel between patients and their families and doctors and nurses.
