[0083] In this embodiment, the data access unit configures a data access interface, and heart failure patients or medical institutions need to log in to the cloud storage database through an authentication mechanism, which includes a user name and password, or uses biometric technology for identity authentication. Only legitimate users who have passed the identity authentication can access the cloud storage database.

[0084] Furthermore, the data access unit adjusts access rights according to the identity of the user to ensure the security and standardization of data access; after successful login, the user chooses to access different information data according to his or her own access rights; after selecting the access data, the user can quickly view the summary information of the data through the data preview function to quickly locate the required content; the data access unit configures the data export function to facilitate users to download data to local devices; in addition, the data access unit supports the data access request function. After the background request is reviewed and approved, the user can access the data without access rights within the specified time.

[0085] At the same time, during the entire data access process, the data access unit will record the user's operation log, including access time, access data category, operation results and other information for subsequent auditing and tracking; in addition, the data access unit regularly updates security policies to respond to potential security threats and ensure the access security of data in the cloud storage database.

[0086] In summary, the ultrasonic cardiogram remote monitoring system for heart failure patients provided by the method of the present invention realizes comprehensive remote monitoring of the heart state of heart failure patients, greatly improves the monitoring efficiency, and can timely conduct early intervention through real-time monitoring and abnormal warning, effectively preventing sudden cardiac events. The use of cloud storage database ensures the safe storage and long-term traceability of information data of heart failure patients, bringing more convenient and efficient medical service experience to heart failure patients; and provides effective data support for medical staff, which helps to formulate personalized treatment plans and further improves the treatment effect of heart failure patients.
