Most countries suffer from a lack of medical equipment. The scale and speed of expansion of the disease mercilessly laid the situation bare. Life-saving equipment may not be produced and delivered on demand and in a short time. Finally, the price may exceed even the posibilities of well-organized countries. Aware of these shortcomings and increase in similar problems, now and in the future, we have recognized that respirators are the key yet scarce medical devices at the current stage. They enable medical services to treat people suffering from infection symptoms and breathing problems, thus prevent the patients´ health from a rapid deterioration. The most important assumption guiding our team is the simplicity of the technical solutions while minimizing their costs and maintaining functionality.
