Design And Implementation Of Data Processing And Printing System For Medical Monitor

With the prosperity and development of medical and health services,medical equipment is also undergoing tremendous change.Nowadays,monitor as a traditional equipment,integrates a variety of functions,like parameter measurement,display and analyze and so on.Real-time data in the monitor's software system provides the doctor with the patient's current life characteristics,which leads to the neglect of the importance of reviewable data In this context,with the new generation of monitor launched,data collection,data processing and print system also features a new design.This article describes a method to achieve data collection,data processing and print system.First,this paper introduces the key technologies in which the system is involved.The key technologies include MVD framework and signal slots mechanism in Qt language,and CUPS print service program and USB driver principle.Secondly,in this paper,the data collection and print system has carried on the detailed design and concrete implementation.The system consists of three parts: data collection,data processing,and print.Before the detailed design and implementation,the requirements including functionality and performance of system are discussed,and the overall architecture and functional structure of the system is designed.Data collection stores the physiological parameter which is transmitted from hardware and processed according to different categories to database.Data processing includes three aspects: data storage,data request and data presentation.The design of database is realized in data storage module.The database doesn't support SQL operations,and the way of key-value pairs stored non-relational database is adopted.The structure of form file and data file for the database is realized in the paper.Print function is divided into two parts: report design and report print.CUPS service is adopted in task processing and it provides applications with a call interface,simplify the print task management and data format conversion.The communication between printer and monitor is based on USB,and this paper realizes the USB driver design under Linux system.In this article,through the data structure design,class diagram design,function design and timing design,every parts of the system is completed.At last,in this article,the testing work of the system respectively from two aspects of functionality and performance.In a functional test,it use unit testing and functional testing as two option,to ensure the availability and completeness of the system,in the unit test,Gtest be used as test framework,it has a detailed unit testing in each function of the system.For functional testing,the test cases are designed by setting different print range of different data types.The system performance testing mainly verifies performance of database and print functions.According to the analysis of testing results,the system can achieve the expected result.
