Aseptium is a company that specialises in technologies for cleaning of complex surgical instruments. One of the core technologies used in Aseptium's machines is ultrasonic cleaning. In this process Instruments are submerged in a liquid and energy is delivered to the surfaces of the instrument in the form of ultrasonic waves that create cavitation bubbles within the liquid volume. When these bubbles collapse shockwaves are generated that remove contamination from adjacent surfaces. Effectiveness of ultrasonic cleaning depends on the uniformity of bubble formation within the entire volume of the cleaning tank, the energy released during bubble collapse as well as bubbles ability to penetrate into intricate details of the surgical instruments. This project: A proposed study would investigate Aseptium's current ultrasonic cleaning system from several perspectives. 1. Measuring ultrasonic activity within the volume and potentially providing feedback to the control system or ultrasonic generator. 2. Create a three dimensional map of cavitation activity in the cleaning tank and identify potential lower activity area, their size and potential impact on cleaning ability. 3. Analyse the nature of the bubble formation and shockwaves within the tank and their ability to remove contamination from instruments. 4.Investigate penetration capability of ultrasonic bubbles into the difficult to clean elements (crevices, holes, joints, channels etc). The project will be undertaken in collaboration with the Cavitation Research Laboratory, Medical and Industrial Ultrasonics, School of Engineering UoG. Research infrastructure includes state-of-the-art high speed cameras, for imaging rapid acoustic cavitation bubble dynamics, and characterising the interaction with instrumentation. Novel in-house developed acoustic detection devices will be adapted and utilised for monitoring, quantification and mapping capabilities. The researcher, under Aseptium's guidance, would gain thorough understanding on cleaning processes and its criticality to healthcare delivery, as well as the key variables for industrial ultrasonic cleaning systems, including through fundamental research into the subject. Aseptium will provide the ultrasonic system and tests to measure cleaning ability as well as all necessary working knowledge to perform the experiments.

Aseptium是一家专门从事复杂手术器械清洁技术的公司。Aseptium机器中使用的核心技术之一是超声波清洗。在此过程中，仪器浸没在液体中，能量以超声波的形式传递到仪器表面，在液体体积内产生空化气泡。当这些气泡破裂时，产生冲击波，从相邻表面去除污染物。超声波清洗的有效性取决于整个清洗槽内气泡形成的均匀性、气泡破裂过程中释放的能量以及气泡渗透到手术器械复杂细节的能力。本项目：一项拟议的研究将从几个角度调查Aseptium目前的超声波清洗系统。1.测量体积内的超声活动，并可能向控制系统或超声发生器提供反馈。2.创建清洗槽中空化活动的三维图，并确定潜在的较低活动区域、其大小和对清洗能力的潜在影响。3.分析罐内气泡形成和冲击波的性质及其清除仪器污染的能力。4.调查超声波气泡进入难以清洁元件（裂缝、孔洞、接头、通道等）的渗透能力。该项目将与空化研究实验室，医疗和工业超声，工程学院UoG合作进行。研究基础设施包括最先进的高速摄像机，用于成像快速声空化气泡动力学，并表征与仪器的相互作用。内部开发的新型声学探测设备将被改造并用于监测、量化和绘图能力。在Aseptium的指导下，研究人员将深入了解清洁过程及其对医疗保健的重要性，以及工业超声波清洁系统的关键变量，包括对该主题的基础研究。Aseptium将提供超声波系统和测量清洁能力的测试以及执行实验所需的所有工作知识。
