In general, conventional continuous positive pressure breathing aids output a gas (such as oxygen) in an inhale mode and supply it to the user at a fixed pressure to increase the pressure in the user's respiratory tract. Further, the gas is sent to the lungs of the user; conversely, in the exhale mode, the conventional continuous positive pressure breathing aid stops outputting the gas, and the lung contraction of the user returns to the original shape. A gas (such as carbon dioxide) produced by the intrinsic gas exchange in the lungs. However, when the user is in a sleep state, the user does not breathe at a constant inspiratory pressure from start to finish. Therefore, when the user uses the continuous positive 2 breath assist H in the sleep state, the user's sleep condition must be touched. The pressure provided by the continuous positive pressure breathing aid in the inhalation mode is exclusively controlled by others. Therefore, such conventional continuous positive pressure breathing aids cause great inconvenience in use. Another conventional continuous positive pressure breathing aid is additionally provided with a gas flow 201105371, the unit, the gas sensing unit _ user in the inhaled or exhaled gas μ 塁 so as to adjust the air flow corresponding to the user immediately The pressure provided in the gas mode ensures the smooth flow of the breather. However, because this type of continuous positive pressure breathing aid only detects the air flow when the user inhales or exhales, it can keep the user's breathing flow under the sleepy g smoothly. The user can maintain good sleep quality while using the continuous positive pressure breathing aid. Therefore, the above-mentioned continuous Zhengli breathing aids obviously have to be improved. SUMMARY OF THE INVENTION The present invention provides a respiratory assist device based on an electroencephalogram signal and a method thereof, which mainly utilizes an electroencephalogram signal of an immediate user to determine whether to adjust the air pressure of the output gas of the positive pressure breathing aid. The value, in turn, allows different users to obtain better sleep quality' for their inventive purposes. The invention provides a respiratory assist device based on brain wave signal and a method thereof, which mainly utilizes an optimized search algorithm to obtain an optimum pressure value from a relationship between a sleep quality and a buckled private value and an output gas pressure value. To make progress to ensure that different users can get better sleep quality for another purpose. In order to achieve the foregoing object, the technical means and the effects that can be achieved by the technical method include: a brain wave signal-based breathing assist device comprising a positive pressure breathing lion, - sleep state monitoring Unit and a control unit. The positive dust breathing aid outputs gas in the inspiratory mode to generate a body and a barometric pressure signal having a pressure value, and stops outputting gas in an exhalation mode. 201105371 body ° shai sleep state monitoring unit According to the sleep, the sleep state is generated...f The user's sleep state, the positive pressure breathing is connected to the number of the control unit, and the control money is found in the brain. The pressure signal, the status signal and the brain wave signal generate a pressure _. The control unit generates the control signal by the ===two-sleep quality indicator value' and when the status signal is received and the 指标(10) quality indicator value exceeds the preset range. The sleep quality index of the auxiliary device based on the brain wave signal is the cyclic alternating mode rate. The control unit of the breathing aid based on the brain wave signal uses the optimized search method to calculate, and the m-ring ring is the same as the most pro-pressure value. The control signal is generated to control the air pressure value of the output gas of the positive pressure breathing aid to be the optimum air pressure value. The invention is based on a brain wave signal-based breathing assistance method, and the steps include a gas/;, a L5 cycle step, a sleep state monitoring step, a sleep quality sensing step, and a wave pressure step. The airflow regulating step detects that the user is inspiratory or = gas N·, and adjusts the pressure value of the output gas of a positive pressure breathing aid until the amount of change in the gas flow obtained by each detection is low. The value of the air pressure is maintained at a pre-value of 预. The sleep state monitoring step detects the sleep state of the user, determines whether the user is maintained for a predetermined time under a non-rapid eye movement sleep state, and calculates and stores one of the user's sleep quality indicator values and the output. A table of relationship between gas pressure values, wherein if the user does not maintain the predetermined time in the non-rapid eye movement sleep state, 201105371 executes the airflow tuning step, otherwise a status signal is issued. When the sleep state monitoring step sends the status signal, the sleep quality sensing step detects whether the sleep quality indicator value exceeds a preset range, and if the sleep quality means that the value does not exceed the preset range, the sleep is performed. The state monitoring step, if the right sleep quality indicator value exceeds the preset range, the brain wave scraping step is performed. The brain wave pressure regulating step is to obtain an optimum air pressure value by using the optimized search algorithm and control the air pressure value of the gas of the positive pressure breathing assistor to be the optimum air pressure value, and then execute the Sleep state monitoring steps.
