Military Medical Equipment Is Equipped With Standard Query System Design And Development

Based on the standards of field medical equipment, strictly according to the normal design method of management information system, the study adopts object-relationship data model to combine medical equipment, the standards, treatment institution and medical service organically, and a multimedia database system of standard of field medical equipment is developed. Meanwhile, in collecting data, the study discusses the establishment and modification of the standard from research methods by investigation on the spot and consulting material.The paper discusses firstly conception of multimedia database, analyses the characteristic of multimedia data, employs object-relationship data model which fits for the database of the study, and uses the method of database linked with files to store multimedia data.In the part of design and development of system, the paper analyses users' requirement for data and management, which means background database should store particular information of medical equipment, outfit standard and medical service and foreground application could carry out query and output easily, put out single scheme by relation and integrality restriction of database, and could realize combination, disintegration, retrieving, updating, analysis and statistics of information, and can be outputted and printed by text, graph and video. Then, the paper implements the design of conception, logical and physical structure of database, achieves the general E-R graph, and transforms it into reasonable data structure, and then optimizes the data model to make it fulfill 3NF. Furthermore, the paper designs general function module of the system, and breaks it down into some child function modules, such as standard child module, medical service child module and equipment query child module, etc. Finally, the database and application are developed by using Borland Delphi. The realization of database is mostly building of database and data tables; the realization of application is mostly programming of the child modules.The end of the paper is the summary of the study. Two primary difficulties of the research are pointed out as following: building data structure and dealing with multimedia data. Then, the paper analyses the characteristic of the system and the feasibility of using OODM to design the database, and points out the best scheme is to use object-relationship data model. Finally, three kernel sectors in the outfit of medical equipment are discussed from viewpoint of ways and means, including equipment, kinds, equipment number and optimization of outfit system. It is effectiveto use scientific method of qualitative analysis linked with quantitative calculation to resolve the outfit problem.The system can provide a query platform of compositive information to equipment managers, teachers and users from outfit standard of medical equipment, medical service of all levels treatment institution and related medical equipment. It can also improve management level of medical equipment construction, meet the requirement of teaching and scientific research of corresponding units. Meanwhile, it will act as a branch system of information integration system of field medical equipment demonstration center to provide information consultation of medical equipment, complete the function of demonstration center, and offer basic means.
