AIR.vs.CORONA Ventilator Machine

Complete medical ventilator

Comment 3

The first test of my ventilator was carried out by the Red Cross Germany - Deutsches Rotes Kreuz

Inspiration

My inspiration is to build a ventilator for low infrastructure areas like Africa and India. A ventilator that can be build around the world.

  • For a very low cost.

  • Only from parts that are already available all over the world.

  • Without 3D printer.

  • Without complex metal structures.

  • Finished parts from the hardware store without changing them significantly.

  • With cheap 5 euro computers that are available worldwide.

  • Operated with a simple electric motor.

  • According to hygienic medical conditions. Easy to clean and disinfect.

  • With a production time of a few hours for one person.

  • For invasive ventilation of coma patients with an Intubation tube.

  • For non-invasive ventilation for breathing support with a breathing mask.

What it does

It is a resuscitator (ambu-bag) squeezer.

There are many similar good ideas with this principle. But some of them are too complicated to manufacture or lack important functions.

The functions of the device are:

  • Respiratory rate (BPM)
  • Inspiration pressure (hPa) or (mBar)
  • Tital volume (cm3)
  • Inspiratory / expiratory ratio (I: E)
  • Inspiration break
  • Programmable pressure curve
  • Display - BPM, breathing pressure, full volume

Optional and still in progress:

  • Assisted ventilation of patient ventilation
  • Trigger for automatic detection of the ventilation request
  • Alarm for Disconnect and leak

External:

  • Oxygen connection O2
  • PEEP valve

Power supply:

  • Socket 230 V AC
  • Socket 110 V AC
  • Car cigarette lighter socket 12 or 24 V
  • Car battery 12 V DC
  • Block battery 9 V DC

The construction:

  • The case is super stable. Ideal for a very rough area.
  • The breathing bag is protected by its housing.
  • If the machine breaks down, the Ambu Bag can be removed quickly. Carry on with manual ventilation.
  • The device has Eurobox dimensions.16 pieces fit on one Euro pallet.
  • Ideally suited for transportation by plane and truck to the affected areas.

How I built it

  • Simple plastic storage euro box.
  • Small computer (microcontroller) Arduino Uno.
  • Servo electric Motor - model building engine.
  • Lashing strap.
  • A few electronic components: switches, LEDs, knobs, LCD Display.
  • Simply printed and laminated control panel.

That's all,...

Challenges I ran into

The biggest challenge was: I have everything done alone.

  • To have an idea
  • plan and draw
  • purchase of all parts
  • build the construction
  • build electronics together
  • programming
  • Test everything
  • Make Youtube videos
  • Social media and the Internet
  • Look for doctors to test the device
  • money for the whole project
  • and so on ...

Accomplishments that I'm proud of

Several doctors think my project is great

If the conditions are met, the Red Cross Germany can imagine using my equipment in crisis areas.

What I learned

How a ventilator works. I met a lot of great people in the medical field.

What's next for AIR.vs.CORONA Medical Ventilator Machine

Red Cross Germany Long-term test over several weeks starts in a few days.Monitored by doctors and specialists.

A production hall with 300 square meters already exists. As soon as capital is enough, I will put the staff together.

Discussions are already underway with doctors who have been providing emergency aid in Africa for many years.

Next i need to find sponsors, investors and donations.

Thank you for your attention and reading my post.
