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.

该拟议项目由共同申请人、西蒙弗雷泽大学 (SFU) Woo Soo Kim 博士团队、不列颠哥伦比亚大学 (UBC) 护理学助理教授、医疗保健合作者 Lillian Hung 博士、目前每天与 COVID-19 患者互动的温哥华综合医院 (VGH) 呼吸治疗科 Ingrid Hakanson 女士、制造商共同努力。 位于不列颠哥伦比亚省温哥华的 Pantheon design 是一家呼吸机制造商，而一家用于批量生产便携式呼吸机的 3D 打印机制造商是位于不列颠哥伦比亚省 Delta 的 Tinkerine。我们在此提出了一种带有折纸管的低成本便携式 3D 打印机械呼吸机的设计和原型设计，用于在大规模流行病和 COVID-19 资源匮乏的环境中使用。所提出的机械呼吸机通过收缩 3D 设计的折纸管来提供呼吸，而不是压缩传统的袋阀面罩 (BVM)。 3D设计的Origami管的体积变化将超过原始体积的85%，而传统BVM的体积变化为25%。因此，所提出的呼吸机的尺寸可以比用于便携式应用的传统呼吸机小得多。 通过及时的投资，该团队将为便携式呼吸机带来关键突破，创建一个成熟的制造平台，准备从优化设计、低成本加工和机械耐用性中受益。拟议的研究为医用呼吸机设计领域提出了一个新方向；专注于便携式呼吸机气囊的制造及其针对 COVID-19 的系统应用的研究项目很少。便携式呼吸机技术已经引起了全世界的兴趣。但是，3D打印可自折叠便携式呼吸机的概念是相当新颖和独特的。因此，加拿大将通过这一发展奠定全球技术优势。我们未来的目标是使 Origami 空气管适用于许多其他类型的机械呼吸机应用。
