Mass ventilator system to combat COVID-19

We are designing a mass ventilator system, that can ventilate 5, 10, 50 or even more people simultaneously, protect healthcare workers, and can be operated outside of hospitals including temporary emergency camps.

Your donation is essential and urgent to  speed up the development, for 2 reasons:

1. COVID-19 is spreading fast, countries are running out of available ventilators
2. Spare parts and sensors that are essential to the development are increasingly difficult to buy on the market


I am Dr. Miklos Kozlovszky, a research and development engineer.

As COVID-19 epidemic was spreading fast, I envisaged a new ventilation concept and designed with my small team a KTG-type mass patient ventilator, that has four essential features:

(1) no need for a dedicated machine for each patient, meaning that one ventilator can ventilate several patients at a time;

(2) patient ventilation parameteres (such as oxygen concentration, pressure, respiration rate, PEEP) can be adjusted individually for each patient according to the doctor’s treatment strategy;

(3) transporting exhaled infectious air from the common airspace, thereby significantly reducing the risk of infection for all medical staff;

(4) the equipment may be installed on an ad-hoc basis in a non-hospital environment, without any hospital infrastructure. 

Now we are a big project team and the mission of our MassVentil project is developing a working prototype for a modular mass ventilator system. Under critical circumstances, this system can be used to simultaneously ventilate a large number of COVID-19 patients with ARDS in critical condition. Detailed blueprints, plans and results are available for free for those who wish to use or rebuild our system during the COVID-19 outbreak.

The Most Important Benefits of the MassVentil Concept:

(1) Current ventilators are limited to supplying only one person at a time. This means that  each patient must have a separate ventilator. This is why  the available quantity is already low and may soon run out in many countries. Our MassVentil solution consists of a central duct system and personal ventilator modules for the individual patients. The central inhalation and exhalation duct system supplies air to and collects gases from all the personal ventilator modules for ventilating more patients at the same time, thereby saving more lives.

(2) Like any other medical ventilators, our mass ventilator system supports personalized patient ventilation. Medical professionals can adjust all important parameters individually (such as oxygen concentration, pressure, respiration rate, PEEP) at each patient according to the treatment strategy.

(3) In our MassVentil concept, the medical ventilator removes (and filters) exhaled infectious air from the common airspace, significantly reducing the risk of infection for all medical staff. MassVentil will  provide safer working conditions. This is a significant improvement on current respiratory equipments where exhaled, infectious air from traditional ventilators exits into the common hospital airspace. Thus putting doctors and nurses at an increased risk due to working in air contaminated with high concentrations of viruses.

(4) When setting up mass health camps an important factor to consider is which equipment can be used without hospital infrastructure. Usually, there are no drainage pipes in the wall and power distribution is limited to each camp bed. Our mass medical ventilator can also be employed ad-hoc, without the need for advanced hospital infrastructure.

Until now, I have personally financed the development of MassVentil. This is a not-for-profit project and all team members have volunteered their knowledge and time for free.  

Together, we strongly believe that our intellectual capital and our collective work can be transformed into saving lives. 

We need to proceed faster and make the prototype ready within weeks, then start testing immediately. To enable us to do this we need to order necessary sensors and spare parts, and pay for services, not only relying on volunteer contributions. The sooner the design is ready the more lives we can save. No doctor should ever be forced to choose which critical patients receive ventilator support, which happens at present due to ventilator shortage. All those in need of breathing support need to have ventilator access.

 Please contribute to help us finalise the design.
