At the plant of the defense complex of the Russian Federation "Progress"(Michurinsk, Tambov region) developed a unique artificial heart designed for children. The main difference of the device from a similar heart for adults is miniature size and power. In terms of size, the children's artificial heart is comparable to ordinary candy.
The case created by military engineers heartmade of titanium, and the inner surface is protected by diamond coating. The supporting mechanism of the rotor, rotating in a magnetic field, is made of a unique, ultra-strong material of comochrome (cobalt, molybdenum and chromium alloy). Details of the heart, according to the developers, practically do not wear out and do not create dust particles. Inside the mechanism, sensors are installed that control the rotor speed to control the blood flow rate.
Two tubes go from the artificial heart,which are connected to the patient’s blood vessels, and a reinforced cable connected to an external control and power system. The child will also have to carry two batteries on the belt - working and reserve (one charge is enough for 12 hours of work). Included with the heart comes a set of tools: titanium wrenches and a special scalpel.
The device is currently being tested on animals.- bulls and pigs. This is not a permanent artificial organ, it provides the vital activity of the body for the period before the donor heart transplantation. The cost of the Russian heart from the defense complex is significantly lower than its foreign counterparts.
The main profile of the plant "Progress" - productioncontrol systems for the aerospace industry. In the shops of the plant, miniature parts the size of a poppy seed and much thinner than a human hair are processed. The assembly section of the plant is equipped with special damping mechanisms that dampen vibrations, which allows for the production of high-precision miniature artificial hearts designed to save the lives of pediatric patients.
