Application of gas detector in hospital

Application of gas detector in hospital field:

Ethylene oxide for short, ETO, is a colorless gas, which is irritating to human eyes, skin and respiratory tract. At low concentrations, it has carcinogenic, mutagenic, reproductive and nervous system hazards. The odor of ethylene oxide cannot be detected below 700 ppm. Therefore, an ethylene oxide detector is needed to monitor its concentration for a long time to prevent harm to the human body. Although the main application of ethylene oxide is as a raw material for many organic synthesis, another main use is for disinfection of equipment in hospitals. Ethylene oxide is a sterilant for steam and heat sensitive materials. It is now widely used during minimally invasive surgery. Alternatives to ETO, such as peroxyacetic acid and hydrogen peroxide plasma gases, still have problems, and their effectiveness and applicability are limited.
At this point, ETO sterilization remains the preferred method:

          A hospital in Henan needs to be evaluated for JCI certification. One of them is occupational health and safety. Real-time monitoring with an ethylene oxide detector is required at the place where ethylene oxide is used, and the data is uniformly sent to the equipment monitoring room. When the concentration exceeds the standard, an audible and visual alarm will be issued, and the relevant security personnel will be notified by SMS. The JCI certification standard is a worldwide recognized medical service standard, representing the highest level of hospital service and hospital management. It is also a certification model recognized by the World Health Organization. Therefore, customers require the ethylene oxide monitoring system to be highly accurate and the SMS alarm to be timely.
