过氧化氢消毒技术在医疗器械感染防控中的应用OA

Objective Because there are many kinds of medical devices and different requirements and methods of infection prevention and control,the qualified rate of disinfection and cleaning quality is low.Therefore,this paper introduces hydrogen peroxide disinfection technology to study the application effect of this technology in the prevention and control of infection of medical devices.Methods This study selected 9 895 reusable medical devices which were representative in a specific clinical environment of a hospital as research objects.These medical devices were widely used in various clinical departments of the hospital,involving the diagnosis,treatment and nursing process of a variety of diseases.On the basis of detailed analysis of various risk factors of infection,the infection risk coefficient corresponding to each risk factor was calculated accurately by scientific statistical method and risk assessment model.Through the quantitative analysis and comparison of these coefficients,six evaluation items with higher risk of infection were finally selected.According to the characteristics and infection risk degree of different medical devices,hydrogen peroxide disinfectant,application equipment and application method were selected,and the application effect of disinfection technology in the prevention and control of infection of medical devices was analyzed in combination with the qualified rate of disinfection of devices,the incidence rate of hospital infection and the sterilization effect of devices.Results After the application of disinfection technology in infection prevention and control of medical devices,the qualified rate of disinfection and cleaning quality of medical devices was more than 80％,which effectively improved the effect of infection prevention and control management of medical devices.Adenosinetriphosphate(ATP)content was always maintained within 200 amol/piece,had a good disinfection effect,and the biological indicators were qualified.Conclusions This technology can effectively improve the implementation effect of infection prevention and control measures for medical devices,not only meet the high quality requirements of clinical disinfection and cleaning of medical devices,but also provide a feasible and effective solution for optimizing infection prevention and control measures for medical devices.
