| Hospital Equipment Information System (HEIS) is affiliated to Hospital Information System (HIS). It can improve hospital internal management. While most parts of hospitals in our country have not worked up their own HEIS.I have been working in Equipment Department, Zhongshan Hospital, Fudan University for 6 years. My job is equipment maintenance and management. Now I am familiar with the processes of hospital equipment management in the tertiary level hospitals. The task of my diploma project is to design and implement a new type of HEIS, which can be satisfied by the tertiary level hospitals in china. The system is different from the common HEIS. It integrates the idea of equipment overall lifecycle management, on the other word, the system can manage hospital equipments for long time and in many aspects. The system not only manages the equipment accounts exactly, but also has the ability to assist equipments counting, and it can manage equipment repairing information.In order to implement the above mentioned functions, the system is divided into three subsystems: database application subsystem,desktop application subsystem and handheld application subsystem. They cooperate and fulfill the whole function together.The main tasks and methods in the design are the following:1. Design and propose the system's architecture and its overall requirements. The system can meet both the requirements of equipment management from hospitals and the requirements of collecting hospital equipment data from the Ministry of Health.2. Design and implement all function modules, according to the real requirements.The hardware system is purchased from other companies, and it contains: server, desktop PCs, laser printer, matrix printer, barcode printer, and handheld PC suite (including barcode scanner and RFID reader), etc. The software system is developed by the writer. The DBMS of the system is Microsoft SQL Server 2000. Microsoft Visual Studio 2005 .Net is the platform of developing desktop subsystem and handheld subsystem, and the program language is C#.In the process of designing the system, the writer resolved several main technical problems that are accessing database, reading and writing files, controling barcode scanner, and RFID reader, and optimizing system performance.3. Transformat the old data in Excel file to the database system.4. Maintenance and optimize the system. When some parts of the system are debugged, they will be tested by my colleagues in real condition. After they find out any problems, I will fix them.This thesis is the conclusion of methods and experience in the system design and implementation. In this thesis, the writer summarizes the background and actuality of HEIS in our country, and proposes a new architecture and overall requirements of HEIS. The paper emphasizes on the design and implementation of handheld application subsystem that is the character and important composition of the HEIS. In addition, the paper also discusses the ideas of designing hospital equipment repairing management model. Finally, the paper discusses the system performance optimization in system design and the effect to hospital equipment management after using the system.In the chapter of design and implementation of handheld application subsystem, the thesis discusses the keypoint of using barcode, RFID technology in detail; proposes 2 kinds of self-defined file format; applies"two binary sort"algorithm. They are very important to upgrade the system performance of device counting. |
