Software Development Of Physiological Signal Conversion And Parameter Setting

Now, technological level and medical standards are in the rapid development ofdomestic and foreign，people are increasingly concerned about health care and health,and the health concerns are also a microcosm of the human body to the vital signs ofconcern. Changes in vital signs, is to determine the main indicators of the patient’scondition. So,for the medical staff and patients, to deepen understanding of thesignificance of vital signs, and always concerned about changes in vital signs, hasimportant significance.At present, the body’s most important vital signs, including physiological signalparameters heart rate, body temperature, blood pressure, respiration rate, pulse rate,oxygen saturation, etc. These parameters can provide many valuable pathologicalinformation, so the storage, testing and analysis of the body’s various physiologicalsignals parameter is important. Physiological signal conversion and parameter settingsoftware is based on the physiological signal management and real-time playbacksystem has been implemented, it is mainly the realization of storage and read a varietyof human physiological signal data, and set up a remote alarm mechanism for viewingand analysis of health care; Meanwhile, the system can also be converted to the dataformat, to realize playback in the playback system.This paper mainly completed the following work:First, this paper describes the purpose and significance of the thesis, and combinedwith practice, analyzes the domestic and foreign research status about this topic andtrend.Second, this paper made brief introduction of the application software designenvironment. Including physiological signal management and real-time playbacksystem and human physiological signal acquisition and storage system is introduced.Among them, the former is the objective of the design basis, and used to make the dataformat conversion after used on the management and playback system; The latter has a format conversion conducted by the data file. In addition, also introduced thephysiological signals of the standards used in this project the characteristics of therecords in the database file and read methods, including the header file (extension. Hea),data file (extension. Dat) and Settings file (extension. The set). Among them, the datafile is mainly introduced the project used in16format; Set file is on the basis of thestandard system of agreement, recorded the multiple physiological signals of differentindividuals and alarm mechanism of related information. Specific read process is asfollows: first of all, through physiological signal management and real-time playbacksystem to read the original data of the header file, the file name, the number of signalchannel, the sampling frequency, storage format and other information into thecomputer memory; After, according to reads the useful information from the file contentof the data file read into memory, in order to realize the signal playback; Finally,through the software realization of the parameter setting and reading, to analyze thevarious physiological signal processing.Third, this paper mainly is physiological signal conversion and parameter settingsoftware involves the relevant data are introduced in detail, mainly includes two parts ofdata, respectively: front-end and threshold detector parameters and the parameters andthe threshold Settings file.Finally, this paper mainly is physiological signal conversion and parameterSettings file protocol and software platform of software design are introduced. Fileprotocol mainly includes the custom data file format and user Settings file format;Software design based on VS2010software development platform, mainly consists oftwo modules, including: data format conversion module and. Set file setting module.The first module, complete the data file format conversion, and generate thecorresponding. Hea file, implementation in the playback of playback system. Thesecond module, used to create the user Settings file. Through this module can to thepatient’s physiological information and alarm mechanism to manually set up and modify,respectively set up in the front part and MT set part of the implementation, and generatethe corresponding configuration files, and can be read.
