As a result of the novel Coronavirus disease (COVID-19) outbreak, a surge is witnessed in the demand for mechanical ventilators needed for treating affected patients. With the rapidly virus spreading around the globe, the shortage of ventilators becomes a global challenge and numerus efforts are followed. While industry mobilizes toward producing medical grade equipment, a number of low-cost and less complex emergency ventilators have been developed, mainly through academic and open-source channels, with a hope to meet any temporary needs gap until medical grade ventilator provision becomes sufficient. Herein, the design and implementation of one such emergency ventilator called GlasVent is presented, which an automated version of manual resuscitator device, commonly known as big valve mask or artificial manual breathing unit bag and widely used prior to initiating the mechanical ventilation. GlasVent uses 3D printed mechanical parts, widely available materials and off-the-shelf electronic and sensing devices which can be fast assembled. Furthermore, it requires minimal training and can be operated manually by hands or legs, thus meeting the emergency requirements even in the low-resource settings or regions with less developed healthcare systems. Post-COVID-19, such ventilators can potentially find use in clinical care of a wider variety of patients with injury, pulmonary noncommunicable diseases, and severe asthma etc.
由于新型冠状病毒病(COVID-19)的爆发,治疗受影响患者所需的机械呼吸机需求激增。随着病毒在全球迅速传播,呼吸机短缺成为一项全球性挑战,人们为此付出了诸多努力。在工业界动员起来生产医疗级设备的同时,一些低成本且不太复杂的应急呼吸机已被开发出来,主要是通过学术和开源渠道,希望在医疗级呼吸机供应充足之前满足任何临时的需求缺口。在此,介绍一种名为GlasVent的应急呼吸机的设计与实现,它是手动复苏器设备的自动化版本,通常被称为大阀门面罩或人工手动呼吸单元袋,在启动机械通气之前广泛使用。GlasVent使用3D打印的机械部件、广泛可得的材料以及现成的电子和传感设备,这些可以快速组装。此外,它所需的培训极少,可以手动操作,也可以用手或腿操作,因此即使在资源匮乏地区或医疗系统欠发达的地区也能满足应急需求。在COVID-19疫情之后,此类呼吸机可能会在对更多类型的受伤患者、肺部非传染性疾病患者和重度哮喘患者等的临床护理中得到应用。
