The objective of this project is to design, manufacture, and assemble a low-cost, user friendly mechanical respiratory ventilator prototype aimed at easing the current shortage of ventilators related to COVID-19 patients, in an emergency timeframe. The proposed ventilator prototype can be manufactured and assembled locally using rapid prototyping tools such as 3D printers and CNC machine tools. The ventilator system includes a variable positive airway pressure unit, source for medical oxygen, sensors for monitoring oxygen and carbon dioxide, expiratory filter exhaust, in addition to the valve for different variable positive airway pressure devices (VPAP). A key innovation is a novel valve for the control of oxygen flow to patients requiring this intervention. The inputs to the valve are air and oxygen. The outputs are controlled oxygen content. The 3D printed valve is used to create a prototype from light metal which is used to create a mold for mass production, using a polymer. The 3D printing design and protocol will allow rapid production of a customized mold for different types of NIV-ventilators that is available for such modification.

该项目的目标是设计、制造和组装低成本、用户友好的机械呼吸呼吸机原型，旨在在紧急情况下缓解当前与 COVID-19 患者相关的呼吸机短缺问题。所提出的呼吸机原型可以使用 3D 打印机和 CNC 机床等快速原型制作工具在本地制造和组装。 呼吸机系统包括可变气道正压装置、医用氧气源、用于监测氧气和二氧化碳的传感器、呼气过滤器排气，以及用于不同可变气道正压装置 (VPAP) 的阀门。 一项关键的创新是一种新型阀门，用于控制需要这种干预的患者的氧气流量。阀门的输入是空气和氧气。输出是受控的氧气含量。 3D 打印阀门用于用轻金属创建原型，然后使用聚合物创建用于大规模生产的模具。 3D 打印设计和协议将允许快速生产适用于此类修改的不同类型 NIV 呼吸机的定制模具。
