What Is 環氧乙烷滅菌器?
An 環氧乙烷滅菌器 (環氧乙烷滅菌器) is specialized equipment designed for the healthcare and pharmaceutical industries. It uses ethylene oxide gas as the primary agent to eliminate all microorganisms from medical devices and supplies that are sensitive to high temperatures or moisture, such as catheters, 起搏器, and surgical optics.
The ETO Sterilization Cycle
The sterilization process follows a rigorous sequence of stages to ensure both absolute sterility and user safety. Below are the five key steps of an ETO cycle:
01. Pre-conditioning
Items are heated and humidified to a specific set point (typically in the chamber or a separate room) to prepare microorganisms for gas exposure.
02. Pre-vacuum
The system evacuates air from the chamber to create a vacuum environment, 確保 ETO 氣體能夠深入滲透到複雜的設備內腔.
03. 環氧乙烷注射
注入環氧乙烷氣體, 通常與惰性氣體混合，例如 氮氣或二氧化碳 以消除爆炸的危險.
04. 曝露
產品在氣體環境中保留預定的時間. 此持續時間根據材料密度和所需的無菌保證水準而變化 (薩爾).
05. 通風
透過反覆空氣清洗和真空循環提取殘餘氣體. 溫度升高加速了包裝和產品材料中環氧乙烷的去除.
根據您的需求量身定制
滅菌時間和效率很大程度取決於您的特定產品, 使用的氣體混合物, 以及您是否使用 單通道或雙通道 系統. BOCON 提供從緊湊型 78L 裝置到大型 900L 工業系統的一系列型號 (BCS系列) 適應各種生產規模.
