Abstract:
Objective:To design and optimize a novel medical detection device of prevention and control for nosocomial infection based on quality function deployment(QFD),so as to enhance the safety and prevention efficiency of medical test.Methods:The design requirements of the device of prevention and control for nosocomial infection were systematically analyzed through QFD method.The requirements of users were integrated and converted into special technical characteristics.And then,the novel medical detection device of prevention and control for nosocomial infection based on QFD was designed.Laboratory testing,simulated clinical testing,and a small-scale clinical trial involved 50 patients from Union Hospital,Tongji Medical College,Huazhong University of Science and Technology were adopted to assess the convenience of operation,and reliability and safety of the results of this device in clinical work.Results:A closed detection device that integrated processing sample,reaction detection and pathogen inactivation was designed,which could reduce operational risks and improve detection efficiency.The sensitivity and specificity of the detection of this device were respectively 97.5%and 95.2%in test of laboratory,and error of repeatability was less than±1.5%.The test time of that was shortened from 30 min of test by conventional equipment to 21 min.The accuracy rate of that in testing 50 patients of clinical trial was 96.8%,and average testing time of each case was 3.5 minutes.Conclusion:The novel medical detection device of prevention and control for nosocomial infection that is designed and optimized by QFD method can effectively enhance the safety and efficiency of medical test,and reduce biosafety risks during operations process.It can provide important theoretical support for the design of medical test device in prevention and control for nosocomial infection.
