Senior First Aid Simulation Of System Development

Emergency nursing is a theoretical and practical disciplines are strong, its teaching objectives are:to strengthen a student's awareness of first aid,emergency care and teach the basic theory and first aid training in the basic operation of technical skills,students in emergency situations quickly assess and correct decision-making and implementation of comprehensive decisive urgent capability.It should fully utilize the existing teaching conditions,the mobilization of both the teaching and learning initiative,in order to achieve the above objectives of teaching. Traditionalteaching methods to better achieve the transfer theory and technology objective,but in cultivating awareness and emergency response capabilities seemed "unable" to make up for past deficiencies teaching methods to further improve the quality of teaching.The use of computers in teaching situation for simulation training will be achieved certain results.Medical students in the school and medical personnel through courses,can be systematically mastered emergency medical theories and knowledge,but lack of patient aid on the spot skills training.The system combines computer,control modules and model,simulate realistic medical cases for students targeted training.Basic training is where names of some basic measures,students need skilled and correct operation.Including CPR training,training in intubation, airway open training defibrillator training.Through a variety of sensor systems,feedback parameters moves back through the figurative to help and said that the training of students.Items in basic training on the basis of need for specific cases and conduct mock emergency.Using dialogue scene,the scene where students train capacity.Students under simulated symptoms,the combination of medical knowledge,diagnosis,treatment imposed,the system under treatment measures,and humbles the set,indicating the disease conversion,then students diagnosis,and to take further steps until the final outcome.system function:1.Topic CoursewareThe use of multimedia technology professional production of courseware, and through slides showing the broadcast.2.Skills training1) basic skills training(operation kept)2) high-level skills training(operation kept)3.Skills assessment1) basic skills examination(for the single operation,the process of retention)2) high-level skills assessment(for the dialogue scenes,the operation kept)4.Management(servers only)1) equipment management2) training and examination performance management5.Tools(servers only)1) development platform for dialogue scenes2) multimedia courseware platform3) Remote Management TrainingDesign Principles:The entire software development process,in order to guarantee the efficiency of the development of software maintainability,demand good development model as a guide.In object-oriented software development design,the better is to study more and more recognized is agile development model.Stress collaboration,refused to change,but welcomed the expansion, it is also crucial to the main thrust of categories,the coupling between packet minimized.This model for the design and beginning to explore very important.In the development process,it must follow the principle of continuously amended.So,throughout the process,we must quickly develop the right ideas for research.to address,key issues:1.Mixed data storage and read outThe preparation and use of the script,the data related to text,pictures and voice data and video data RTF format of data preparation and storage, use of more than one document is stored on the cluttered,and are inconvenient to access.It is difficult and MFC framework documents related to this request relates to the data,regardless of format,should be stored in a unified document,so that we can be certain files and file extensions linked.Compound document to meet the requirements,to study with the use of documentation.Compound document is constructed using COM,so we should also study the COM technology.2.Computers and communications technology MCUWhere one system is used for actual training of the emergency,to simulate realistic reality of the situation is very important.People in emergency simulation internal installed many of the sensors and simulation of the controller,the sensor signals to.control the one handmovements components, on the one hand and to convey it to connect computers.In order to simulate many situations,sometimes sensors directly to the signal transmitted to the computer,and the action by the controller given by the computer to control the signals.In short,computers and internal microcontroller signal transmission is the key,generally use the serial or USB ports, communications,requested a reasonable deal.Computer communications are specialized components,such as serial communications components,to study the use of these components. 3.Database TechnologyThe system involves a lot of information,training point of information, class information,the information students,teachers information, examination information,script information.These messages to efficient management,it is necessary to use the database,the computer training centers have database,the overall server must have databases,which should be able to coordinate work on database design is very important.According to the data volume and cost of different options of different databases. It may relate to a variety of databases.4.Web services technologyIn order to achieve stable operation of the database and safety requirements in the database outer join Web services,Web services are now distributed software development frequently used technology.It uses Soap agreement between the network data transmission,shielding the bottom of the communications network operations,it is very convenient to use, the use of Web services and called on local function almost.The development of web services and the use of more yes.Net or Java,we use language is the development of MFC,not only to build web services MFC wants to study the use of web services approach.5.ActveX technologyTo the browser able to reproduce the original real-time operation,the website to use ActiveX controls,it is used to interpret the script and operating logs,the website will be the scene of reproduction.Development ActiveX controls are a number of ways,but the latest is a faster method is to use C # to develop.Therefore,to study C #.Net to develop ActiveX control.Innovation points:1.Used in the MFC.NET technology mixed programming.2.MFC programming in the use of other technologies such as Flash, Html,PowerPoint,and so on.3.Used the Com + to ensure the synchronization of distributed database update.
