医院设备维修信息系统对提高医疗质量及效率都起着重要的作用。通过对医院设备维修需求分析，制定了总体功能架构。根据与设备维修流程有关的输入输出数据、表单、表格分析，找出实体－属性联系，做出E-R图并生成关系数据库表。软件开发应符合维修工作实际流程需要，用户界面友好，操作灵活，该软件通过统计分析能对故障产生的原因做出分析。%Hospital equipment maintenance information system plays an important role in improving medical treatment quality and efficiency. By requirement analysis of hospital equipment maintenance, the system function diagram is drawed. According to analysis of input and output data, tables and reports in connection with equipment maintenance process, relationships between entity and attribute is found out, and E-R diagram is drawed and relational database table is established. Software development should meet actual process requirement of maintenance and have a friendly user interface and flexible operation. The software can analyze failure cause by statistical analysis.
