Özet

© 2022 IEEE.With this study, a new test system was designed to be used in the sterilization of all critical medical materials used in the health sector. A new type of oxygen molecule allatrope (YOMA) from reactive oxygen species (ROS) was developed for use in the system, tested and compared with other sterilization systems. Before the test, 12 different materials, each of the same size (2 cm2), were sterilized in an autoclave at 120 °C, 1 atm pressure for 20 minutes. In the second stage, all surfaces of the samples were contaminated with the 3M Attest 1264 Geobacillus stearothermophilus biological indicator, which was cultured in an oven at 37 °C. In the designed system, all test samples were taken into sterile petri dishes, each sample test material was placed on the solid medium surface and then taken into the desiccator. It was checked whether there was bacterial growth as a result of the 18- 24 hour incubation of the samples in an oven at 37 °C for 30, 45 and 60 minutes. It has been determined that the system, which was designed and tested with spore-forming bacteria, has a sterilization rate of 100% and there is no growth on the materials. As a result, compared to the systems that sterilize medical equipment with gas; A system that does not need additional consumables, does not harm equipment, is environmentally friendly, consumes less energy, can be sterilized faster and at lower temperatures with YOMA has been developed and its effectiveness, effect and reliability have been tested.
