Objective To discuss the medical consumable materials and its storeroom management techniques. Methods From techniques view, it was thoroughly discussed the concrete operating regulations of applying, check in, check out, storeroom specific management, data statistics and second-level storeroom of consumable materials. Results It basically included all contents of management of consumable materials, It has important directive function for medical consumable materials informational management and department of equipment management. Conclusion Economic benefit and socialeffect can be more exerted through the usage of management techniques of medical consumable materials, and more full-scale service can be provided.

Objective To discuss aspects of medical equipments data information management techniques:medical equipment information management and hospital equipment management system naming regulations which are the core of hospital medical equipment data information management techniques. Methods From view of techniques,it thoroughly discussed concrete techniques regulations of each part. Results It has important directive function for medical equipments informational management and department of equipment management. Conclusion Establishment of medical equipment information management will promote hospital management level enormously,and more and more emphasis are being placed on it.

Objective: With the increasing amount of medical materials used in the hospital,they are becoming one of the major sources of medical risks.How to control this risk has become a common concern in the medical world.The authors investigated how to enhance the safety and validity of medical materials.Methods: We established a total quality control system for medical materials to keep them under strict quality control at all stages,and a monitoring and reporting system as well to prevent undesirable consumption of medical materials.Results: The quality of medical materials was insured,and medical material-related accidents were prevented.Conclusion: The quality control system greatly improved the application safety of medical materials in the hospital.

Objective To improve hospital power quality and guarantee the stability of medical equipment. Methods Leg of circuit is taken for power supply. Refining plant is equipped for electric barbed wire. Conditions are improved for equipment access. Power quality monitoring is strengthened. Results Power quality is effectively improved while the failure rate decreases obviously. Conclusion It is essential to improve power quality for high medical equipment quality.

With more and more equipments installed,the quality of power in hospital becomes worse and worse,which seriously threatens the safety of equipments.To assure medical devices running stably and improve the quality of power supply,we adopted the method of brunch power supply and power net purifying instruments in improving the condition of equipments switched on power and monitoring power quality,so that the supply quality in hospital was improved,as well as equipments trouble rate was decreased.

The necessity and importance of medical equipment quality control are analyzed on the basis of clinical cases of ventilator using.It is necessary because it assures the technical performance in the process of medical diagnosis and treatment.It is important because it extends the work range of medical engineers in hospital,changing them from the state of passive maintenance to active quality control,thus contributing to the combination of engineering and clinical diagnosis and treatment.Further more,it promotes the development of clinical medical engineering in hospital.

With the appearance and development of ultrasonic surgical installation, ultrasonic therapy enters on a new epoch. High-amplitude and high-power ultrasonic vibration produced during the operation, ultrasonic surgical installation can be used to decrease the amount of bleeding or stop bleeding according to the acoustic properties of different tissues. The part where pathological changes happen can be excised selectively by ultrasonic surgical installation. This article introduces the principle, structure, classification and clinical application of ultrasonic surgical installation in detail.

This paper introduces the basic theory of BP neural network and develops a model for assessing bid of medical equipment based on BP neural network. A case is analyzed with the model, and the result shows the high accuracy of it.

This paper introduces a virtual ECG sampling system based on LabVIEW. The system, utilizing self-developed ECG sampling card, fulfils ECG measurement and A/D conversion safely and realizes ECG data processing and display under Labview developing environment.

50Hz power frequency interference is the main noise of ECG signal.With the signal processing toolbox of MATLAB,this paper develops a high-performance 50Hz notch filter.The design method is relatively simple compared with other methods and the application result verifies its efficiency.
