        Que tal, Sergio aquí, estamos evaluando la adaptación de este diseño a la cadena de suministro mexicana. Unir manos esfuerzos nos ayudara. Ya estamos en contacto con la cámara de comercio de Sinaloa y organizando revisiones con especialistas. Si alguien está trabajando en entre proyecto o tiene información favor de contactarme sergio@aquaexploracion.mx

        • Galel Fajardo

          En Honduras también. La UNAH tiene estudiantes de ingeniería con prototipo pero quieren cooperar y aprender. El diseño de MIT tiene ya bastante historia y revisiones. Mejor es usar lo probado y no reinventar la rueda.
          Ánimo LatAm. ¡Saldremos de esta, juntos!

    Good day, Mexico is dealing with the COVID pandemic but our country infraestructure is limited, i am interest in ventilators in order to fabricate it to support people from my town.

    • larry gessman

      I tried to simplify the MIT design using a linear actuator to compress the ambu bag. It could be easier to manufacture because it is an available part. A linear actuator can also be made by a motor turning a threaded rod. Email me at larrygessman@gmail.com if you want to see a video of my demonstration prototype, or get more information.

      Hi, I’m electrical engineer from Pakistan, here we’re facing the covid-19 pandemic like rest of the world. Since the infraestructure of my country is limited therefore I am interest in low cost ventilators in order to fabricate them to support people from my country and rest of the world.

  3. Diego Rivera

    I’m from Guatemala. We are deeply concerned on the exponential growth of this pandemic and want to recieve as much information as posible to start prototyping the ventilator, and possibly provide an option for the people affected.

  6. Mostafa Kashani

    Dear Researchers,
    I am from Iran and facing the same issue; would the design package become open source?


    We are part of a group of entrepreneurs in the Amazon Region in Brazil who are endevouring what is possibles to bring ideas and new low-cost technology for assembling or producing ventilator to help hospitals and ambulances during the coronvirus fight. We need your help and ideas so we can stay put and firm during this illness.

  8. Guna Govind

    Dear Researchers,

    I live in San Diego, CA and basically from India. I’m very interested in building this product as soon as the working prototype is available. My interest is to build and make it available on emergency situation. I can get the respective Government permissions and connect with manufacturing units on not-for-profit basis. All the best with your research.

    Hi All: Just registered today here, as this E-Vent web site was recommended to me. I have designed a number of ICs and integrated SOCs. In process of becoming familiar with all the specifications for ventilators.
    I have an immediate comment/question on the power supply. It is specified as 12V and 5A nominal (typ). Later, the description mentions 15A spikes/surges. If the 15A “events” are occurring, are observable, or are expected during this ventilator’s normal operation do please upgrade the power supply requirement from [12V and 5A nominal] to [12V and 15A nominal].

    From the reliability point of view it also makes sense to have a single 12V & 15A typ power supply (one component) than having a 12V & 5A typ supply plus an added capacitor to handle 15A spikes (two components) / or a 12V additional battery.

    For redundancy purposes, yes, an additional 12V battery makes sense as a stand-by power-failure backup. I would recommend that the single main power supply be capable to handle well the 15A load spikes in a repetitive manner.

    • Mohit Bhartiya

      spikes are not power drawn but the surge due to the motor being stopped suddenly. hence it would be a reverse power surge that needs to be suppressed. Also for starting toque few capacitors can provide the necessary boost. no point in increasing the cost of the power supply. also as per the power calculations given we only require around 26w of power. 60w power input is already over compensated.

      • Dan Hariton

        Hi Mohit: in common practice, to suppress the 15A spike generated each time the motor turns off, would like to mention that “Flyback diodes are commonly used when inductive loads are switched off by semiconductor devices: in relay drivers, H-bridge motor drivers, and so on” (Wikipedia). A capacitor is not necessarily needed in conjunction with the power supply when the motor turns off.
        Understood that these 15A spikes are not drawn from the power supply, so the power supply itself can be defined as 12V and 5A typical/max (we are not doing any fancy inductor-stored energy-recovery).
        Still this means 60W. Where can I find info on the “around 26W power calculation given” please?

        Capacitors are used at times for motor startup. So if my updated understanding is correct, we have
        A) no added capacitors are used in conjunction with the power supply, and
        B) capacitors are used in conjunction with the motor turning ON
        C) motor turning OFF generates 15A spikes that need to be suppressed

    • Yueh Lee

      James – based on the latest guidance from the FDA – what exactly is needed for approval in the US? What testing, documentation, etc? I think we would all appreciate expertise in understanding this, especially from an engineering, then subsequently manufacturing perspective. Clearly there will be no “1” device. Thanks. Feel free to reach out directly, also, I’ve asked our regulatory team the same question.
