Proyecto MASI - Electrical and Mechanical fabrication files

This data set contains the blueprints, board and schematic files corresponding to the design presented in: "Masi: A mechanical ventilator based on a manual resuscitator with telemedicine1capabilities for patients with ARDS during the COVID-19 crisis". In this article, we introduce a portable and low-cost ventilator that could be rapidly manufactured, to meet the increasing demand of ventilators worldwide produced by COVID-19 pandemic. These ventilators should be rapidly deployable and with functional capabilities to manage COVID-19 patients with severe acute respiratory distress syndrome (ARDS). Our implementation offers robustness, safety and functionality absent in existing solutions to the ventilator shortage (i.e., telemonitoring, easy-to-disinfect, modularity) by maintaining simplicity. The design makes use of a manual resuscitator as the core respiration component activated by a compression mechanism which consist of two electronically controlled paddles. The quality measurements obtained after testing on a calibrated artificial lung demonstrate repeatability and accuracy exceeding human capabilities of manual ventilation. The complete design files are provided in the supplementary materials to facilitate ventilator production even in resource-limited settings. The implementation of this mechanical ventilator could eliminate device rationing or splitting to serve multiple patients on ICUs.

本数据集包含与论文《Masi：一款基于手动复苏仪的机械呼吸机设计——面向COVID-19疫情期间急性呼吸窘迫综合征（ARDS）患者的远程医疗（telemedicine）功能型设备》对应的工程蓝图、电路板文件及原理图文件。该论文提出了一款便携低成本且可快速量产的呼吸机，以应对COVID-19全球大流行引发的全球呼吸机需求激增问题。此类呼吸机需具备快速部署能力，并可用于治疗罹患重度急性呼吸窘迫综合征的COVID-19患者。本设计通过保持简洁性，实现了现有呼吸机短缺解决方案所不具备的鲁棒性、安全性与功能特性，具体包括远程监护（telemonitoring）、易消毒、模块化等特点。该设计以手动复苏仪作为核心呼吸组件，通过由两个电控推杆组成的按压驱动机构实现触发运作。在经过校准的人工肺上进行测试后所得的质量检测数据显示，本呼吸机的呼吸参数重复性与精度均超越人工手动通气的人类操作水平。完整的设计文件已作为补充材料发布，以便在资源受限的环境中也能推进呼吸机的生产制造。该机械呼吸机的应用可消除设备配给限制或拆分使用的需求，为重症监护室（ICU）内的多名患者提供独立的呼吸支持。
