OBJECTIVEResearch for establishing a risk monitoring theoretical model of high risk medical equipment at applying site.

METHODSRegard the applying site as a system which contains some sub-systems. Every sub-system consists of some risk estimating indicators. After quantizing of each indicator, the quantized values are multiplied with corresponding weight and then the products are accumulated. Hence, the risk estimating value of each subsystem is attained. Follow the calculating method, the risk estimating values of each sub-system are multiplied with corresponding weights and then the product is accumulated. The cumulative sum is the status indicator of the high risk medical equipment at applying site. The status indicator reflects the applying risk of the medical equipment at applying site.

RESULTEstablish a risk monitoring theoretical model of high risk medical equipment at applying site.

CONCLUSIONThe model can monitor the applying risk of high risk medical equipment at applying site dynamically and specially.

Objective:Give a method for tracing boundary of inner-medium membrane in the ultrasonic image of common carotid artery.Methods: Giving a cost function before the programme begins to search the pixel point set whose cost function have the minimum value. The searching process starts from an initial anchor point given by the precedent programme. The calculation of cost function on each pixel point column on both sides of the initial anchor point will not stop until the terminal conditions are fulfilled. The programme will record the coordinates and pixel values of all the points with the minimum cost function value obtained from the calculation.Results: It can trace the boundary of inner-medium membrane in the CCA image from a clinical exam and can export the processed image with highlighted area. There is a daemon that records the coordinates and pixel values of the point set.Conclusion: This method can trace the boundary of inner-medium membrane in the CCA ultrasonic image when the CCA image is distinct.

Medical equipment quality control is the core content of hospital management. It runs through the whole process of medical management, including the purchase, the installation and acceptance, the use and maintenance, the abandonment. The contents and measurements of the medical equipment quality control are introduced in the four processes. It can help hospitals carry out dynamic management for medical equipment quality control and set up a scientific and perfect quality control system.

Objective: To enhance the safety of intravenous infusion and reduce the working strength of the nursing staff, a novel auto-switched intravenous infusion system was developed. Methods: The system was controlled by a low power consumption microchip. A signal was detected when the infusion was finished in one channel and then a cam mechanism was used to switch the infusion channel automatically under the supervision of the microchip. Results:A novel auto-switched intravenous infusion system was proposed and analyzed. The proposed concept is innovative, feasible and of functionality. Conclusion: The proposed auto-switched intravenous infusion system is cost effective and practical. It has potential applications and can benefit for improving current intravenous infusion situation.

The medical consumable material management is an important part of logistic support in the management of hospital, but the hospital has many weak links in the management of supplies. This paper aims to explore the common problems (especially in clinical use) existing in the management of medical consumables and years of management experience in Changhai hospital's practice, then discusses lean management from the perspective of lean management
