随着COVID-19的影响在全球蔓延，近几个月来医院放射科感染控制程序的重要性越来越明显。依赖于人工应用化学消毒剂的现有消毒程序是耗时的、资源密集型的并且易于发生高度的人为错误。替代的非接触消毒方法，如紫外线杀菌辐照（UVGI），有可能克服现有方法的许多局限性，同时显着提高工作流程和设备利用率。本研究的目的是调查在放射学环境中使用机器人UVGI设备消毒表面的杀菌效果和实际可行性。我们提出了一种机器人UVGI平台的设计，该平台可以与人类工作人员一起部署，并可以在狭窄的房间内自主操作，从而解决了将该技术集成到放射学环境中所需的两个重要要求。在一家医院，我们在CT和X光室进行了实验。在第二家医院，我们调查了机器人在部署后在<15分钟内对CT室进行消毒时的杀菌性能，据估计，这一时间段比目前在感染（或潜在感染）患者后对房间进行消毒的实践快2-4倍。两个测试地点的结果表明，UVGI成功灭活了24个表面中22个表面上的所有可测量的微生物负荷。在剩下的两个表面上，UVGI分别将微生物负荷降低了84%和95%。该研究还揭示了手动消毒放射科套件的一些挑战，揭示了难以到达的地方的高浓度微生物负载。我们的研究结果提供了令人信服的证据，表明UVGI可以有效地将微生物固定在放射科套件中通常接触的表面上，即使它们只暴露于相对较短的辐射爆发。尽管照射时间短，但我们证明了能够杀灭具有更复杂细胞结构的微生物，并且需要比SARS-CoV-2更高的UV灭活能量，因此表明对冠状病毒有效的可能性很高。
The importance of infection control procedures in hospital radiology departments has become increasingly apparent in recent months as the impact of COVID-19 has spread across the world. Existing disinfectant procedures that rely on the manual application of chemical-based disinfectants are time consuming, resource intensive and prone to high degrees of human error. Alternative non-touch disinfection methods, such as Ultraviolet Germicidal Irradiation (UVGI), have the potential to overcome many of the limitations of existing approaches while significantly improving workflow and equipment utilization. The aim of this research was to investigate the germicidal effectiveness and the practical feasibility of using a robotic UVGI device for disinfecting surfaces in a radiology setting. We present the design of a robotic UVGI platform that can be deployed alongside human workers and can operate autonomously within cramped rooms, thereby addressing two important requirements necessary for integrating the technology within radiology settings. In one hospital, we conducted experiments in a CT and X-ray room. In a second hospital, we investigated the germicidal performance of the robot when deployed to disinfect a CT room in <15 minutes, a period which is estimated to be 2–4 times faster than current practice for disinfecting rooms after infectious (or potentially infectious) patients. Findings from both test sites show that UVGI successfully inactivated all of measurable microbial load on 22 out of 24 surfaces. On the remaining two surfaces, UVGI reduced the microbial load by 84 and 95%, respectively. The study also exposes some of the challenges of manually disinfecting radiology suites, revealing high concentrations of microbial load in hard-to-reach places. Our findings provide compelling evidence that UVGI can effectively inactivate microbes on commonly touched surfaces in radiology suites, even if they were only exposed to relatively short bursts of irradiation. Despite the short irradiation period, we demonstrated the ability to inactivate microbes with more complex cell structures and requiring higher UV inactivation energies than SARS-CoV-2, thus indicating high likelihood of effectiveness against coronavirus.
