Obstetrics Nursing and Medical Health System Based on Blockchain Technology.

Blockchain, as an emerging force transforming the Internet, has applications in finance, logistics, public services, and other fields. It will also have a huge impact on the medical and health industry. The salient features of blockchain technology include guaranteeing information security and user privacy, decentralization, without the involvement of third-party trust institutions, and being able to establish a high-value input and output two-way system, which has a very important application space in obstetric care, medical, and health. The traditional medical and health system is far from being able to meet the information exchange between doctors and individuals. Therefore, building an interconnected obstetric care and health system based on blockchain technology is the direction of future obstetric care and medical development. This paper has conducted an in-depth study of the obstetric care medical health system, with the help of the Internet of Things, blockchain, and other technical means; the purpose is to realize the sharing and security of medical data and to break the limitations of traditional user information. This paper builds a medical electronic health record system model and a hybrid consensus model based on blockchain technology to realize the safety and transparency of patients' personal medical information data and achieve two-way communication and interconnection of information between doctors and patients. This paper analyzes the current status of domestic and foreign medical and health systems and the blockchain-based medical electronic health record system. It is concluded that the domestic investment in medical and health in 2018 was as high as 113.2 billion yuan, and the entire investment scale is continuously expanding. Pay attention to the health system. In the future, the obstetric care and medical health system based on blockchain technology will surely be realized and improved.
