Abstract:
Objective:To design an inspection system for quality of metabolism tester based on alcohol combustion mode for human body,so as to realize assessment for accuracy degree of human metabolism tester.Methods:According to the specific indicators that were measured by the metabolism tester for human body,a simulation of bidirectional controllable flow and a simulation of component concentration of exhaled breath were designed and realized.Then,the ratio of alcohol consumption to oxygen consumption and carbon dioxide production were calculated by the formula of alcohol combustion.Finally,the metabolic indexes(volume of gas flow,oxygen consumption,dioxide carbon production,rate of energy metabolism,respiratory quotient)that were outputted by the inspection system for quality were calculated according to Weir formula.Furthermore,the verification for precision of simulation modules of exhale and inhalation,and weighing device module was carried out,and an application test of inspection system for quality was also carried out.Results:The errors of the volume of gas flow and alcohol consumption that were outputted by simulation modules of exhale and inhalation,and weighing device module were all within±1%,and the errors between the reference value of the metabolic index of the inspection system for quality and the actually measured value of the metabolic index of the hood calorimeter were all within 10%.Conclusion:There was higher consistency between inspection system for quality of metabolism tester for human body and the actual measurement data of calorimeter,which can better simulate the process of respiratory metabolism of human body,and provide standardized testing means for the performance verification of metabolic tester.
