Obective To research and build an evaluation index system of emergency medical rescue capabilities (EMRC),and then put forward a new assessment method of EMRC.Methods A competency model of EMR was established by using Competency Model,then an evaluation index system was constructed on base of analyzing the factors of EMRC,and an evaluation model was set up based on four-element connection number of set pair analysis (SPA).Results The example showed that the calculation of the model was relatively simple,and the assessment results were to be believed,and moreover,its multiple functions could make up for the shortage of the single function of other evaluation models.Conclusion This method is scientific and rational to some extent,and can provide reference for similar evaluation problems.

The concept and principle of 3D printing technology were described,and its advantages were expounded according to the demands of emergency medical equipment.The application of 3D printing technology in the field of emergency medical equipment was analyzed from six aspects,such as equipment system,disposition model,development and innovation,use-pattern,maintenance methods,comprehensive benefit etc,to provide the references to the future construction and development of emergency medical equipment.It's pointed out 3D,4D and 5D printing technologies were of great significance for driving the development of emergency medical equipment.
