[Theoretical model study about the application risk of high risk medical equipment].

Objective: Research for establishing a risk monitoring theoretical model of high risk medical equipment at applying site.

Methods: Regard 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.

Result: Establish a risk monitoring theoretical model of high risk medical equipment at applying site.

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