Implementing Medical Technological Equipment in the OR

from the Article: "Operating rooms (ORs) more and more evolve into high-tech environments with increasing pressure on finances, logistics, and a not be neglected impact on patient safety. Safe and cost-effective implementation of technological equipment in ORs is notoriously difficult to manage, specifically as generic implementation activities omit as hospitals have implemented local policies for implementations of technological equipment. )e purpose of this study is to identify success factors for effective implementations of new technologies and technological equipment in ORs, based on a systematic literature review. We accessed ten databases and reviewed included articles. )e search resulted in 1592 titles for review, and finally 37 articles were included in this review. We distinguish influencing factors and resulting factors based on the outcomes of this research. Six main categories of influencing factors on successful implementations of medical equipment in ORs were identified: “processes and activities,” “staff,” “communication,” “project management,” “technology,” and “training.” We identified a seventh category “performance” referring to resulting factors during implementations. We argue that aligning the identified influencing factors during implementation impacts the success, adaptation, and safe use of new technological equipment in the OR and thus the outcome of an implementation. The identified categories in literature are considered to be a baseline, to identify factors as elements of a generic holistic implementation model or protocol for new technological equipment in ORs."

Money after Money: disassembling Value/Information Infrastructures

This book is a journey through coexisting, emerging or speculated about, types of digital value transfer infrastructures. Using digital value transfer infrastructures as a central case study, this thesis is concerned with unpacking the negotiation processes that shape the governance, design and political purposes of digital infrastructures that are closely linked to the public interest and state sovereignty. In particular, the papers that are assembled in this manuscript identify and inspect three main socio-technical developments occurring in the domain of value transfer technologies: a) the privatization and platformization of digital payment infrastructures; b) the spread of blockchain-based digital value transfer infrastructures; c) the construction of digital value transfer infrastructures as public utilities, from the part of public institutions or organizations. Concerned with the relationship between law, discourse and technological development, the thesis explores four transversal issues that strike differences and peculiarities of these three scenarios: i) privacy; ii) the synergy and mutual influence of legal change and technological development in the construction of digital infrastructures; iii) the role of socio-technical imaginaries in policy-making concerned with digital infrastructures; iv) the geography and scale of digital infrastructures. The analyses lead to the argument that, in the co-development of legal systems and digital infrastructures that are core to public life, conflicts are productive. Negotiations, ruptures and exceptions are constitutive of the unending process of mutual reinforcement, and mutual containment, in which a plurality of agencies – expressed through legal institutions, symbolic systems, as well as information and media structures – are entangled.

Disassembly 4.0: A Pragmatic Approach to Achieve Sustainability in Engineering

This chapter explains in brief what is needed to achieve more sustainable manufacturing processes. It develops both aspects of sustainable, economic, and technical feasibility with most focus on the latter. Remanufacturing processes are described together with relevant factors that enhance their effectivity and efficiency. An overview is given of what kind of shopfloor innovations are required in the near future and some suggestions on how digital and other Industry 4.0 technologies could help to move toward circular manufacturing.

The Assembly and Disassembly Process Guided by Software Agents

Author supplied: A manufacturing process can be described by a sequence or combination of production steps. Based on this approach a manufacturing system has been developed that is capable to produce several different products in parallel. A batch size of one unit is possible and the production is pull-driven. The manufacturing system is based on agent technology and a special so-called product agent collects information about the assembly process. This agent will be connected to the actual product and can guide the disassembly process at the end of the products life. The agent will show the inverse steps to be taken to take a product apart. This approach can be used in the agent based manufacturing process described in this paper but the concept can also be used for other manufacturing systems. The paper discusses the possibilities as well as the restrictions of the method proposed here.

Disassembly Strategies for Remanufacturing

This paper describes some explorations on the concept of disassemblability as an important circularity indicator for products because of its severe impact on reuse value. Although usefulness of the concept for determining disassembly strategies and for improving circular product design clearly shows in earlier studies, the link with Industry 4.0 (I4.0)-related process innovation is still underexposed. For further technical development of the field of remanufacturing, research is needed on tools & training for operators, diagnostics, disassembly/repair instructions and forms of operator support. This includes the use of IoT and cobots in remanufacturing lines for automatic disassembly, sorting and recognition methods; providing guidance for operators and reduction of change-over times. A prototype for a disassembly work cell for a mobile phone has been developed together with researchers and students. This includes the removal of screws by means of a cobot using both vision & the available info in the product’s Bill-Of-Materials, the removal of covers, opening of snap fits and replacement of modules. This prototyping demonstrates that it is relatively easy to automate disassembly operations for an undamaged product, that has been designed with repairability in mind and for which product data and models are available. Process innovations like robotisation influence the disassemblability in a positive way, but current indicators like a Disassembly Index (DI) can’t reflect this properly. This study therefore concludes with suggestions for an evaluation of disassemblability by looking at the interaction between product, process and resources in a coherent way.
