Anesthetic Control System Based On Multiple Inputs Data Fusion

With the development of society, human beings nowadays concern about not only how to survive but also how to increase life quality. The development of medical science provides enough objective tools to pursue the goal. Surgeon aims to help those in need. The surgery anesthetic technology, as a method to alleviate people's pain and accelerate the process of surgery, plays an essential role in surgery. Until now, most hospitals use the technology of human anesthetic, and this process requires experienced and skilled doctors. So this situation demands the realization of automatic anesthetic technology. In order to make the process more convenient, this thesis offers the idea of using multiple inputs as variables, to analyze the physical features of patience, and finally achieve the goal of closed-loop automatic control based on data fusion.The thesis gives the detailed information about the anesthetic depth and monitoring methods, illustrates the basic principle of anesthetic machines--its structure and developing trend, then talks about the theory of quantitative anaesthesia and its realization, shows the ways of using data mining technology to preprocess data, specifies the how to utilize the clustering method to fuse data.The thesis provides the method of using multiple inputs fusion to solve the problem of measuring influences of different variables to anesthetic depth. Data fusion utilizes the information of redundancies and compensations to evaluate the actual parameters of controlled objectives to the greatest extent. In the meantime, data fusion makes the designing of controller and algorithms much convenient, and offers feasible conditions to simplicity of the system.The thesis casts the vision forward and makes a summary of anesthetic control system based on data fusion in the end. This technique is advancement towards old system which based on human experience, saves a lot of human resources, enhances the effectiveness of anesthetic, avoids the waste of resources, compresses the surgery time length, and in the end, guarantee the smooth process of surgery. Although the research over the project is almost at the level of theory, but through carefully analyzing the application value, the vision of the project is optimistic. I am looking forward to the day when anesthetic control system could completely replace human anesthesia.
