Design And Implementation Of Mobile Maternal And Child Health Care Medical System

In view of the high cost and inefficiency of the traditional medical model,the mobile health care service model is gradually emerging.This model provides maternal and child health care services to pregnant women through the high degree of portability and real-time communication of smart phones.In this context,we design and realize a mobile maternal and child health care system,the main work of the paper are summarized as follows:1.We establish a demand model from the perspective of pregnant women,doctors and administrators.According to the result UML case diagram analysis,the key requirements of pregnant women include easily access to maternal and child health information,record signs of data to monitor their own health status in a timely manner,convenient remote medical advice and diagnosis.The doctor's key requirements include view pregnant women signs data and Q&A.According to these requirements,the functional modules of the mobile client and the background management system are designed.Then,we establish the logical architecture,including the application layer,the service domain layer,the data access layer and the data layer,and gives the hierarchical structure design of the mobile client.2.We achieve the function that pregnant women synchronize and storage signs data at any time.In order to allow pregnant women to synchronize the sign data on the mobile client at any time,we use the HttpURLConnection network request mode and JSON to achieve communication between client and server,and then call the server RESTful API interface to synchronize data to the remote MySQL database.For non-network connection problem,we use SQLite mobile database for data backup and synchronize data when network connection is restored,two solutions are combined to realize data persistence store.3.In view of the needs of pregnant women,we design a good special human-computer interaction interface.We enhance the user experience through a reasonable layout of all function modules.We use the custom ListView list control and phonetic Chinese sorting method to display pregnancy knowledge,inspection items,hospital information,and provide a fuzzy query interface to facilitate pregnant women to obtain maternal and child health information.We display the user sign data graphically,and use different colors to distinguish the normal data,abnormal data and standard range,so that pregnant women can intuitively understand their own health status.4.We use the Android OS and Grails framework to achieve the prototype system and verified the wok.We analyzes the technical points of Android,including layout method,custom control,multi-thread mechanism and WebSocket.These technologies are integrated into the development of mobile clients,and we introduces the open source library to improve the efficiency of development.Contrast with other Web frameworks such as Struts and JSF,Grails has more concise configuration,more efficient coding,we use it to achieve the system server to ensure the quality of the software and improve the efficiency.Based on the above two technologies we achieve the system,and run successfully in the real machine.Finally,the function and performance of the system are tested.The results show that the function of the system is correct and the performance meets the requirements,the feasibility and rationality of the system are also verified.
