Monitoring system for stroke

1. A stroke monitoring system, comprising:

a database configured to store user's health information;

a measurement unit configured to be worn by a user or installed in a specific place to measure a biometric signal and store the measured biometric signal in the database;

a stroke determination unit configured to calculate a reference range of the user's biometric signal based on the health information pre-stored in the database and further configured to compare and analyze the biometric signal measured by the measurement unit with the reference range to predict a chance for occurrence of a stroke in the user;

a notification unit configured to notify the user or a designated place of the prediction by the stroke determination unit;

a stroke history storage unit configured to store the prediction by the stroke determination unit; and

a signal device installed in a user living space selected from the group consisting of an exercising space for exercising, a sleeping space for sleeping, and a driving space for driving a vehicle,

wherein the measurement unit is configured to wirelessly communicate with the signal device when the measurement unit is located within a communicable range from the signal device,

wherein the measurement unit is further configured to identify which living space the signal device is installed to detect a state of the user selected from the group consisting of an exercising state, a sleeping state, and a driving state,

wherein, when the user is in the exercising state, the measurement unit is configured to measure the biometric signal comprising an electroencephalogram, an electrocardiogram, a heart rate, and a skin conductivity,

wherein, when the user is in the sleeping state, the measurement unit is configured to measure the biometric signal comprising the electroencephalogram, the electrocardiogram, the heart rate, the skin conductivity, an electrooculogram, an electromyogram, and a blood pressure,

wherein, when the user is in the driving state, the measurement unit is configured to measure the biometric signal comprising the electroencephalogram, the electrocardiogram, the heart rate, the electromyogram, and the blood pressure,

wherein the stroke determination unit is configured to calculate the reference range that changes depending on the user's state detected by the measurement unit, wherein the stroke determination unit is configured to compare and analyze the biometric signal measured by the measurement unit with the reference range specifically calculated for the user's state to predict the chance of occurrence of the stroke.

2. The stroke monitoring system of claim 1 , wherein the stroke determination unit is configured to calculate the reference range based on the user's health information stored in the database and further based on prior predictions stored in the stroke history storage unit.

3. The stroke monitoring system of claim 1 , wherein the user's health information includes a medical checkup history, medical checkup information, and user's measurement electroencephalogram information.

4. The stroke monitoring system of claim 1 , wherein the notification unit is configured to output a notification sound to the user or people around the user or configured to transmit a predetermined signal to a family member, a guardian, or an emergency medical center, when notifying the user or the designated place of the prediction.

5. The stroke monitoring system of claim 1 , further comprising:

a psychological analysis unit configured to analyze the biometric signal measured by the measurement unit to check a psychological state of the user and store the checked psychological state in the database,

wherein the stroke determination unit is configured to use the user's psychological information stored in the psychological analysis unit when predicting the chance for occurrence of the stroke.
