To introduce the basic working principle of TCL - II medical injection pump, the detailed description of the power circuit and motor drive circuit. According to the basic principle of each function, it gave the corresponding circuit diagram for peer reference. Injection pump in the maintenance can use this typical working principle and the typical electronic circuit to realize the common troubleshooting quickly and accurately.

Objective: The system of quality control management of medical equipment is an important management means to maintain medical security, achieve quality control management by the information technology, and it can quickly improve the efficiency of management and increase the effectiveness of the management. Methods: Using the tools of B/S of three layer architecture technology, the management of medical device adverse event, assessment of medical equipment, management of medical equipment scrap, management of medical metrology certificate, and other functions are developed. Results:The adverse events, examine, scrap, certificate management, and other functions are designed through the software, the quality of the equipment is mastered in time through different testing cycle of data comparison, so that the related departments can take preventive maintenance to make the equipment in good state. Conclusion: The informational system of quality control management is used to promote the modernization of medical management and guarantee effectively the quality and safety of medical equipment.

Objective:To analyze and evaluate the uncertainty of spectrophotometer detection device, stability, repeat-ability, the accuracy of the standard testing devices for the detection of spectrophotometer in laboratory.Methods: To calculate the uncertainty of measurement of standard gear, stability, repeat ability for evaluating the accuracy of the standard device.Results: According to the national standard, through analysis and calculation, the veracity and reliability of standard device were proved.Conclusion: Through analysis and evaluation, the uncertainty of verification device of spectrophotometer met the requirement of value. The repeatability and stability complied with the requirement of standard establishment. It can use in detection spectrophotometer, and make sure the results accurate and reliable.

Objective:To design the medical equipment quality control management system and it can improve the efficiency of management, and provide data of quality evaluation of equipment for purchasing.Methods: Quality control management system adopts three layer architecture technology of B/S and publishing tools of IIS, it can implement the various functions of quality control in the management.Results: The system realized some function, like data entry, modify, query and extracting features, et al. The system can evaluate the performance of the equipment through the data analysis. So the maintenance department can preventive maintenance through the data. The equipment is insured in good condition, the purchasing department choose stability equipment in clinical. Conclusion: Quality control management system can evaluate the quality of the medical equipment through the testing data, at the same time the system can intuitive understanding controlled state of the medical equipment for managers, the mangers can take the effective measures to ensure the safety of the medical equipment quality through the system.

Objective:According the review of three grade hospital, it is analysis the problems that evaluation experts pointed out. We can take effective measures and improve insufficient of control management to increase management efficiency. Methods: We can perfect quality control management system, improve the assessment mechanism, establishment of information management system to strengthen the quality control management of medical equipment. Results:After implementation of improvement measures, improve the management mechanism, the quality control management come into the information, scientific management stage. Conclusion:Through the review, we can promote construction by evaluation;the quality control and management work are improved. We can ensure the quality and safety of medical equipment, which can give full play to efficiency, better services for patients.

To establish a consumables supermarket management system to realize the informatized management of the consumables supermarket. The system used SOA as the main architecture, and IIS manager as the pub-lishing tool. The system had the workload, materials and financial resources decreased while the efficiency in-creased, and made the supervisor master the sale information timely. Consumables supermarket informatized management may decrease the hospital's needs for current capital as well as the links, while increase the hospital effi-ciency greatly.

Objective To develop an equipment purchase process management module based on B/S architecture to standardize hospital equipment purchase process and promote hospital informatization. Methods Service-oriented architecture (SOA) was adopted as the main architecture, and internet information service (IIS) manager was used as the publishing tool.Results All the departments could visit the system through hospital intranet and perform on-line equipment purchase and inquiry for progress.Conclusion The system facilitates the inquiry of all departments for the progress of equipment purchase, and standardizes and optimizes the equipment purchase process.
