Development of a Portable Mechanical Ventilator using 3D Origami Tubes to Fight COVID-19

该拟议项目涉及共同申请人西蒙弗雷泽大学（SFU）的Woo Soo Kim博士团队，医疗保健合作者不列颠哥伦比亚省（UBC）护理学助理教授Lillian Hung博士，温哥华总医院（VGH）呼吸治疗部Ingrid Hakanson女士（目前每天与COVID-19患者互动），呼吸机制造商，Pantheon design，温哥华在BC，和一个3D打印机制造商的便携式呼吸机，Tinkerine，三角洲在BC的大规模生产。我们在这里提出了一种低成本便携式3D打印机械呼吸机的设计和原型制作，该呼吸机带有Origami管，用于大规模流行病情况和COVID-19资源贫乏的环境。所提出的机械呼吸机通过收缩3D设计的折纸管而不是压缩传统的袋阀面罩（BVM）来输送呼吸。3D设计的Origami管将改变其体积超过原始体积的85%，而传统BVM的体积变化为25%。因此，所提出的呼吸机可以变得比用于便携式应用的传统呼吸机小得多的尺寸。 通过及时的投资，该团队将为便携式呼吸机带来关键性突破，创造一个成熟的制造平台，有望从优化设计、低成本加工和机械耐用性中受益。拟议的研究在医疗呼吸机设计领域提出了一个新的方向;很少有研究项目专注于制造便携式呼吸机气囊及其在COVID-19中的系统应用。便携式呼吸机技术已经引起了全世界的关注。但是，3D可打印的自折叠便携式呼吸机概念是相当新颖和独特的。因此，加拿大将在这一发展中拥有全球技术优势。我们未来的目标是使折纸空气管多功能的许多其他类型的机械呼吸机的应用。

The proposed project involves a joint effort between Dr. Woo Soo Kim's team at Simon Fraser University (SFU), a co-applicant, Dr. Lillian Hung, Assistant Professor in the University of British Columbia (UBC) Nursing, a Healthcare collaborator, Ms. Ingrid Hakanson, Vancouver General Hospital (VGH)'s Respiratory Therapy Department who are currently interacting with COVID-19 patients daily, the manufacturer of the ventilator, Pantheon design, Vancouver in BC, and one 3D printer manufacturer for mass production of the portable ventilator, Tinkerine, Delta in BC. We propose here the design and prototyping of a low-cost portable 3D printed mechanical ventilator with Origami tubes for the use in mass pandemic situation and resource-poor environment with COVID-19. The proposed mechanical ventilator delivers breaths by contracting 3D designed Origami tube instead of compressing a conventional bag-valve mask (BVM). The 3D designed Origami tube will change its volume more than 85 % of the original volume, which is compared with conventional BVM's 25 % volume change. Therefore, the proposed ventilator can become much smaller size than the conventional one for the portable application. With a timely investment, the team will generate pivotal breakthrough for a portable ventilator, creating a full-fledged manufacturing platform poised to benefit from optimized design, low-cost processing, and mechanical durability. The proposed research presents a new direction within the medical ventilator design sector; there are very few research projects focusing on the manufacturing of a portable ventilator air bag and their systematic applications for COVID-19. The portable ventilator technology has already generated worldwide interest. But, 3D printable self-foldable portable ventilator concept is quite new and unique. Therefore, Canada will be poised with a global technology advantage with this development. Our future goal is to make the Origami air tube versatile for many other types of mechanical ventilator applications.
