After introducing the predominance and status of remote maintenance,the paper lays emphasis on analyzing its application in medical equipment and problems to be solved in the development.Besides,the developing trend of remote maintenance is forecasted.Remote maintenance is one of the development directions for medical equipment maintenance support.

Objective To develop a database management system specially applied for medical equipment maintenance administration, Methods Under PowerBuiider/SQL Server development environment, the C/S mode system structure was confirmed and the system function modules were designed. Results The application of C/S mode structure was coincident with the division-cooperation work flow in large and medium hospitals, and the design of function modules met the demand of information collection and utilization of medical equipment maintenance.Conclusion The database management system can preserve the information of medical equipment maintenance effectively and facilitate its usage. Moreover, many statistical indexes about the maintenance administration are available in this system.

Objective To perform multi -condition combination query in the browse window based on PowerBuilder datawindow technology. Methods After the interested combination of query conditions specified on certain columns in datawindow was constructed by if...then statement, the setfilter () and filter () function was used to retrieve and display data which met the filter criteria. Results A flexible query object was incorporated into the data browsing window. Conclusion The datawindow-based query is suitable for situations where batch of data are filtered against not so many columns.

Biomedical sensor is a key component to the modern medical instrument,which can convert physiological value to electrical signal.After introducing and analyzing the definition,main uses and present application of biomedical sensor,this paper lays emphasis on its developing trend.

Relative problems in the digital management of medical equipment are explored.Study contents include digital hospital and digital medical equipment,main digital management fields of medical equipment,new progress in technique of digital management.It is pointed out that the digital management of medical equipment is an important part of hospital digital construction,which needs discussion and improvement in practice.

Objective To access images of medical equipments in database management system. Methods Images in SQL Server2000 can be stored inside database tables directly as the binary content of a Blob field. Under the PowerBuilder development environment, SelectBlob and UpdateBlob are used to perform the data exchange between the Blob field and a Blob variable defined in Powerscript,then image contained in the Blob variable can be constructed in a picture control available in PowerBuilder. Results It is convenient and expeditious to insert, update and present images in this PowerBuilder application. Conclusion Processing images in the medical equipments database management system extends its functions and has a significant applied value.

Objective To develop medical equipment management information system for medical engineering department. Methods Under PowerBuilder9.0/SQL and Server2000 development environment, the C/S mode system structure was adopted, and the system function modules, such as data input, browsing, querying, statistical analyzing, report generating, were designed. Results Data exchange between client and server was realized. Meanwhile, the designed function modules achieved normal operation. Conclusion The system structure and functions meet the requirements of working practice in medical engineering department.

Objective To construct a new molecular biological method for the analysis of microbial species in lower respiratory tract infections based on 16S rRNA gene by denaturing high-performance liquid chromatograph(DHPLC).Methods The universal primer set was analyzed basing on the highly conserved regions of 16S rRNA gene.DNA amplicons of lower respiratory tract were analyzed by DHPLC to generate peak profiles respectively.The incorporation of 40-bpGC clamp into the amplification primet was essential to effectively discriminate genetic differences identification.Results The primers could only amplify bacterial 16S rRNA.Bacterial of amplicons which incorporation of a 40-bpGC clamp were effectively discriminated genetic differences in DHPLC.The results of clinical isolares identification showed 100%according with the traditional method.Conclusion DHPLC has not only high accuracy,but also is a convenient,rapid and high-through technique for the discrimination bacteria.It has potential value in the detection of lower respiratory pathogenic bacteria.

Based on the practice of workflow, information management system about medical equipment was developed and its functions such as gathering, browsing, inquiring and counting were introduced. With dynamic and complete case management of medical equipment, the system improved the management of medical equipment.
