The following information refers to a development within the framework of the fight against COVID19.
Keep in mind that the correct way to obtain these devices is to order them from approved manufacturers, therefore, as soon as you have the opportunity to receive these products from a manufacturer, you must use that channel.
Also note that there are patents on this type of device. It is known that manufacturing companies are donating plans and advice, however starting a production for profit, for example, it could be violating patent rights. There has been no study of intellectual property that could be affected by the use of the product in each of the territories. Get informed.
Files must be analyzed and validated before use. It is also necessary for a health authority to be responsible for the validation of the product resulting from the use of these contents. Do not use in a medical treatment a product not validated by a health professional and the proper health authorities.
In any case, our intention is to inspire and provide previous work to all those who can take these files and can take responsibility for putting in place a safe solution that saves lives. This necessarily involves verifying that the technical solution that we propose is viable, with the corresponding organizations in your country, and that the solution that you propose based on these elements that we make available to you, does not pose a health hazard.
We present the results of the tests carried out, and we make a series of recommendations that you must verify for yourself, and verify that under the conditions that you are going to implement this solution, the system works as you need it to work.
If you do not have the possibility of assuring 100% that the result of the device that you are going to manufacture from these plans is safe and effective, you should know that the responsibility for the damages that it may cause is solely yours, and that is why we ask that you put this solution in the hands of your local administration or government so that you receive expert assistance, and its implementation is 100% safe and verified by experts.
If you are an individual, humanitarian organization or NGO operating in a poor developing country, while the pandemic lasts and there is a need in your country that cannot be satisfied by the commercial offer of these devices, you have our permission to use, modify and distribute these files, including this document, always under your responsibility. If you modify the design, this document is no longer valid, and you do not have the right to use it, unless you modify it, therefore, you are responsible for everything that appears in that new version.
If you are a government or a company that can afford the production and marketing of this product, you must contact us for special granting conditions .
If you, despite having these files, cannot manufacture the helmet, contact us on the contact section of this website, and we will try to help you.
Understanding that in some cases it is this or nothing, I wish with all my heart that you can find a solution inspired by our work, and can save other people’s lives.
A greeting and good luck,
DOWNLOAD THE MANUAL
- This device creates a pressurized space, and therefore has a pressurized air outlet. You should always put a filter in the air outlet, or the virus will spread throughout the room.
- If you put a suitable filter and guarantee the tightness of the entire device, the propagation stops.
- In the intubation and de-intubation operations, you must take into account that there is a high risk of contagion, due to the existence of aerosols. Use a protective screen or protect yourself with PPE.
- The materials in which the parts are manufactured cannot be porous, they must be watertight, otherwise the virus will infect the environment.
- The PEEP valve is a valve that maintains a positive pressure and therefore a volume at the end of the expiration, with the aim of opening (recruiting) alveoli that would otherwise remain closed, thus protecting from lung damage.
- Take into account that this device must have a constant flux of air and pressure, or the patient could suffer asphyxia, and if the patient is unconscious, can cause death. So asure that there is always supply of air/oxigen and pressure.
