When high-risk groups for the above diseases encounter accidents and cannot receive emergency treatment in time, they are very likely to miss the precious opportunity for rescue.

[0003] At present, first aid methods for people at high risk of disease usually have the following problems: (1) Unable to call for help on their own, such as sudden fainting, accidents when living alone or going out alone, etc.; (2) Low efficiency of calling for help, such as language communication barriers such as nervousness and impatience of the caller, dialect and slurred speech; (3) It takes a lot of time to find the patient, such as the address information is wrong, the address information is vague or the range is too large. Summary of the invention

[0004] In view of the above problems, the present invention aims to provide a method and system for automatic first aid for people at high risk of disease.
