Ventilators were crucial in sustaining the lives of critically ill COVID-19 patients during the pandemic, but the overwhelming demand and prolonged use by patients had led to severe shortages of this vital medical equipment. A newly developed mechanical ventilator initially created as an emergency solution during the pandemic, now offers a high-efficiency, budget-friendly alternative to help address the global scarcity of such devices..

在大流行期间，呼吸机对于维持重症COVID-19患者的生命至关重要，但患者的压倒性需求和长期使用导致这种重要医疗设备严重短缺。新开发的机械呼吸机最初是在大流行期间作为紧急解决方案而创建的，现在提供了一种高效，预算友好的替代方案，以帮助解决此类设备的全球稀缺问题。。

Engineers at Villanova University (Villanova, PA, USA) had designed, developed, tested, and validated an affordable ventilator called NovaVent, priced at less than USD 800. The device is designed to be robust, scalable for mass production, and meets essential performance criteria for treating COVID-19 patients.

Villanova大学（美国宾夕法尼亚州Villanova）的工程师设计，开发，测试并验证了一种名为NovaVent的经济型呼吸机，价格低于800美元。该装置设计稳健，可扩展用于大规模生产，并符合治疗COVID-19患者的基本性能标准。

NovaVent utilizes readily available components to deliver continuous mandatory ventilation (CMV) for patients who are unable to breathe by themselves..

NovaVent利用现成的组件为无法自行呼吸的患者提供持续的强制通气（CMV）。。

NovaVent’s unique, patented design allows for the regulation of tidal volume, a critical factor in supplying adequate ventilation while avoiding lung injury. Users can modify settings via its control panel, and alarms become activated if the prescribed conditions are not met. Performance-wise, NovaVent delivers CMV nearly as effectively as its pricier counterparts—about 90% of the efficiency—but at a fraction of the production cost.

NovaVent独特的专利设计允许调节潮气量，这是提供足够通气同时避免肺损伤的关键因素。用户可以通过其控制面板修改设置，如果不满足规定条件，则会激活警报。在性能方面，NovaVent提供CMV的效率几乎与其先前的效率相当-约为效率的90%，但只是生产成本的一小部分。

Initial tests were conducted on a lung simulator, and further refinements were made using another simulator. The Villanova engineers have now been awarded a patent for the development of this novel type of mechanical ventilator..

最初的测试是在肺模拟器上进行的，并且使用另一个模拟器进行了进一步的改进。Villanova工程师现已获得开发这种新型机械呼吸机的专利。。

“The need for this equipment goes beyond COVID-19,” said C. Nataraj, Ph.D., professor of Mechanical Engineering at Villanova University. “Ventilators like NovaVent are critical parts of the medical infrastructure that are also needed to help the treatment of lung disease, cardiac arrest, strokes, brain injuries and more.”.

Villanova大学机械工程教授C.Nataraj博士说：“这种设备的需求超出了COVID-19。“像NovaVent这样的呼吸机是医疗基础设施的关键部分，也需要帮助治疗肺部疾病，心脏骤停，中风，脑损伤等。”。

“It is especially heartening to visualize the humanitarian aspects of NovaVent,” Nataraj added. “We are looking forward to working with like-minded partners to make such critical, life-saving technology affordable to all people regardless of where they live or how affluent they are.”

Nataraj补充说：“可视化NovaVent的人道主义方面尤其令人振奋。“我们期待与志同道合的合作伙伴合作，为所有人提供如此关键的挽救生命的技术，无论他们住在哪里或他们的富裕程度如何。”
