Development of the Sterilization Box for Medical Equipment with an Ozone Gas Leak Sensor Feature

Abstract

One of the efforts to control the growth of microorganisms is sterilization. The sterilization process can use ozone gas, which is a triatomic form of the element oxygen. Ozone acts as an oxidizing agent capable of destroying the structure of bacterial cell walls, and their molecules are unstable and easily decomposed into oxygen, so that ozone can be applied in sterilization technology for medical devices. In this work, a sterilization box with an ozone generator has been designed with a MQ-131 ozone sensor as an indicator if there is a leak in the box. The output voltage of the ozone generator is 4 kV with a current of 30 mA. We developed an instrument using an Arduino nano as a microcontroller for reading sensor values and displaying sensor values on an LCD monitor. For testing the sterilization effect of the ozone box, a Staphylococcus aureus bacterial sample was used. For the sterilization object, we designated stethoscopes and thermometers as medical equipment. The optimum time for sterilizing medical devices on the sterilization ozone box was 20 minutes, which can reduce the colony of S. aureus bacteria with an ozone concentration of 4.94 ppm.

Electrospun poly(ɛ‐caprolactone) membranes modified with heparin and essential fatty acids for biomedical applications

“…In terms of practical applications, ozone is often used as a sterilization method due to its oxidative properties and ease of decomposition. It has been used for sterilizing medical equipment and eliminating bacteria in the soil 22 . In wastewater treatment, ozone is typically paired with chloramines to inhibit biofilm growth on membranes, with ozone reducing flux decline and chloramines mitigating biofouling by dissolved organics 23 …”

Construction and Characterization of the Diode and Triode Electron Sources for EBM 300 keV/20 mA

“…Prominent applications of EBM are the cross-linking of wire and cables (Seung-Tae et al, 2022), surface curing of materials (Fichtner et al, 2021), sterilization of medical products (Gotzmann et al, 2018), and food irradiation (Pillai and Pillai, 2021). When EBM is used for sterilization, this technology has more benefits than sterilization using UV light (Widiyati and Poernomo, 2018), gamma rays (Febriasari et al, 2021), or ozone gas (Abuzairi et al, 2022) EBM is commonly employed for mass production due to its non-reliance on Co-60 radioactive sources, fast sterilization process, and environmentally friendly nature. The EBM has also been used to study materials sciences (Lee et al, 2022), as well as to do vulcanization of the natural rubber latex (Reowdecha et al, 2021).…”
