Due to FDA’s sterilization innovation challenge and the EPA’s new restrictions on ethylene oxide (EtO) emissions, there has been heightened attention across the healthcare industry to find and broadly adopt alternative sterilization modalities on an accelerated timeline. A select few alternatives seem to be rising to the top, including chlorine dioxide gas (ClO2). While ClO2 has been used as a sterilant in various industries for years, including healthcare, it’s use in healthcare has been minimal compared to EtO and there is an opportunity for industry to better understand this modality. I recently discussed this technology with Emily Lorcheim, Project Manager at ClorDiSys Solutions, Inc, a ClO2 provider with over 20 years of experience servicing the healthcare segment. Emily provided me with a lesson in history and basic ClO2 gas properties, as well as the benefits and potential watchouts when considering ClO2 for medical device sterilization.
基础知识:
自 20 世纪 80 年代以来,ClO2 一直被用作气体灭菌剂,用于处理饮用水和食品。它通常被 EPA 认为是安全的,而且 ClorDiSys 的气体产生是 EPA 注册的灭菌剂。灭菌在室内进行(可提供各种尺寸,以支持单个无菌屏障系统或多个托盘),可外包进行合同灭菌或带到内部用于现场灭菌。
与 EtO 类似,ClO2 是一种真正的气体,这意味着它具有出色的分布和穿透性。但与 EtO 不同,ClO2 在室温下采用这种形式,这对于与 EtO 循环期间发生的高温不相容的敏感装置(如电子或冷链产品)来说是有利的。在灭菌浓度下,ClO2 无致癌性、不易燃且无爆炸性。它呈黄绿色,可以用光度仪实时监测,以控制在腔内释放。它也是水溶性的,提供穿透水的能力,这不是所有的消毒剂都能做到的。
好处:
注意事项:
随着行业不断寻求 EtO 替代品,了解器械和包装材料兼容性、可扩展性、后勤和财务影响以及环境影响的来龙去路将变得至关重要。不会有一种解决方案可以解决灭菌创新的挑战,但 ClO2 肯定是一种需要密切关注的模式,并在不久的将来进行测试。你可以在这里了解更多关于 ClorDiSys 及其灭菌技术的信息!
