摘要：

我们提出了一种可行的简单机械呼吸机原型，旨在作为COVID-19患者的最后手段。该原型实现了压力控制的连续指令通气模式（PC-CMV），具有可设置的呼吸速率、吸气/呼气时间比和FiO 2调制。虽然安全，但设计的目的是尽量减少技术部件的使用，而这些部件在工业中很常见，因此在后勤短缺或中断的时候，或者在技术材料较少的地区，可以以较低收入国家负担得起的中等成本建造。大部分装置可以通过适当的技术手段制造，并提供了施工方案。

英文摘要：

We present a viable prototype of a simple mechanical ventilator intended as a last resort to ventilate COVID-19 patients. The prototype implements the pressure-controlled continuous mandatory ventilation mode (PC-CMV) with settable breathing rates, inspiration/expiration time ratios and FiO2 modulation. Although safe, the design aims to minimize the use of technical components and those used are common in industry, so its construction may be possible in times of logistical shortage or disruption or in areas with reduced access to technical materials and at a moderate cost, affordable to lower income countries. Most of the device can be manufactured by modest technical means and construction plans are provided.
