Design And Evaluation Of Hemodialysis Machine’s Interactive Electronic Technical Manual

The IETM(Interactive Electronic Technical Manual)technology is one of the products of the information age,which plays an important role in the entire life cycle of the equipment.At present,various information IETM technologies are in full swing,but research on IETM interface design has not yet gotten good results.To improve user experience and information search efficiency,the hemodialysis machine is used as object to study the IETM interface design.The main work of this research includes the following aspects:(1)According to the latest IETM national standard GB/T 24463 and the most widely used S1000 D standard,the basic functions of IETM system are summarized.In combination with the specific usage scenarios of hemodialysis machine,the functions that need to be implemented in the hemodialysis machine IETM system are concluded,and making use of the advantages and characteristics of the mobile terminal to achieve these functions is within the scope of this study.(2)The complexity of the equipment makes the amount of information in the IETM increase.As a result,locating the target information in so much information quickly becomes difficult.For the IETM system,the information architecture directly affects the efficiency of information location.Mean response time is the standard to evaluate the tree information architecture in the mathematical model,which is established in this research.Experiments were conducted to obtain the parameters of Hick/Hyman Law between the IETM information of hemodialysis machines.Based on the parameters obtained,the optimization method of the IETM system was analyzed and summarized.(3)Based on the above results and the specific usage scenarios,the interface of the hemodialysis machine’s IETM were designed.(4)Evaluation of the usability of the interface obtained above.The fuzzy comprehensive evaluation method is adopted,in which the analytic hierarchy process is used to evaluate the weight of the evaluation criteria and the fuzzy evaluation method is used to collect the evaluation matrix of the interface.The comprehensive evaluation results show the interfaces perform well in terms of efficiency of information location,and also indicate that the future optimization direction of the interface is to improve the overall consistency of the interface.
