Research And Implementation Of Transmission And Management System For Medical Data Information

With the continuous improvement of living standards,more and more middle-aged and elderly people will suffer from various chronic diseases.With the rise of smart devices,many home health management systems have emerged.However,medical health equipment such as blood pressure monitors,blood glucose meters,and weight scales have encountered many problems when they are used.Many systems can only correspond to one manufacturer's medical health equipment,which makes them incompatible with other manufacturers' equipment.Therefore,in order to solve the problem of incompatibility between medical systems and medical health equipment,various protocols and standards have been proposed.At the same time,ISO/IEEE organizations and international standardization organizations such as CEN have developed the IEEE 11073 standard,a medical data collection and transmission specification.Among them,the Continua Health Alliance uses the IEEE 11073 standard protocol as the main protocol stack.More than200 members have joined the alliance,and its certified medical devices are compliant with the IEEE 11073 standard.Through the research and analysis of IEEE 11073 standard,this thesis realizes the transmission and management system of medical data information based on Android platform.The medical equipment such as sphygmomanometer,blood glucose meter and weight scale complying with IEEE 11073-104 zz standard can transmit data to the client.First of all,this thesis designs and implements the data transmission module,which mainly realizes the health data collection function,that is,the medical health equipment automatically sends the measurement data to the client.The data transmission module is divided into four parts: HDPService,data interaction component,CoreService and UI application by loosely coupled design method.The data interaction component is a key part of the data transmission module and is written by the C language.Based on the IEEE11073-20601 standard,during the data collection process,the data interaction component is responsible for controlling the interaction process between the client and the medical health device and processing the data packet.This thesis chooses the Bluetooth protocol as the transport layer protocol,designs HDPService to establish the transport layer connection between the client and the device,sends the data packet to the data interaction component,and the data interaction component processes the data packet,and sends the data to the UI application after processing.CoreService serves as a bridge between HDPService,data interaction components,and UI applications.Secondly,for the data transmitted,this thesis implements the data management module,which mainly realizes the functions of health data measurement,data local storage and remote synchronization.After the health data measurement is completed,it will be stored directly in the local SQLite.By establishing a secure connection between the selfsigned CA and the server,the user can synchronize the data to the remote server,which effectively protects the user's data information security.Finally,the system was tested using Continua-certified medical health equipment.The test results show that the system can connect with the medical health equipment of IEEE 11073-104 zz standard and carry on data transmission,and also verify that the system has the function of data management.Test requirements have also been met in terms of system stability.
