Hospital EO Gas Sterilizer
Introduction to Hospital EO Gas Sterilizer
A hospital EO gas sterilizer is a low-temperature sterilization system designed for Central Sterile Services Departments and operation theatres. It uses ethylene oxide gas to safely sterilize complex, heat-sensitive instruments such as endoscopes, catheters, anaesthesia circuits, and plastic-based devices. By maintaining controlled temperature, humidity, and gas concentration, hospital EO gas sterilizers help prevent cross infection and support strict infection control protocols in modern healthcare facilities.
Working Principle and Process Flow in Hospitals
The hospital EO gas sterilizer works on a sealed chamber concept where instruments are loaded after cleaning, drying, and packing in EO-compatible pouches. The cycle begins with pre-conditioning, where temperature and humidity are raised to the required level. EO gas is then introduced at a controlled concentration for a defined exposure time so that the gas penetrates packaging and reaches internal surfaces. After exposure, an aeration or degassing phase removes residual EO from instruments, making them safe for patients and staff.
Types of Hospital EO Gas Sterilizers
- Compact EO Gas Sterilizers for CSSD use in small and medium hospitals.
- High-capacity EO chambers for multi-speciality hospitals with high instrument turnover.
- Fully automatic microprocessor-based EO sterilizers with programmable cycles.
- EO gas cartridge-based systems for safe handling and minimal gas wastage.
