Russian engineers have developed the first device in our country for transporting donor hearts at human body temperature without cooling. Thanks to this innovation, doctors will have not four but six hours to deliver the transplant, which is crucial for transporting organs to remote areas, writes "Izvestia". Specialists from the Moscow Institute of Physics and Technology (MIPT) have created a unique device for transporting donor hearts intended for transplantation. This is the first Russian system where the organ can be transported without cooling, at body temperature. When transported on ice, the donor heart remains viable for transplantation for about four hours; the new device extends this period by one and a half times. Currently, the developers have prepared a prototype in the form of a container that is placed in an ambulance. In addition to the chamber itself, the device includes a system for ensuring the heart's viability, fluid pumping systems, and humidity support systems to prevent the organ from drying out. Traditionally, the donor heart is transported in a special solution at a low temperature. This slows down metabolism to extend the organ's viability. The developers used a liquid called "Normacor," which includes polysaccharides and ions that maintain its viability at body temperature. Additionally, MIPT specialists have devised a way to monitor the heart's condition using a video camera and several light sources. Constant monitoring provides the necessary information about the donor organ's state. In the future, the developers plan to adapt the device for transporting other internal organs. They are currently refining their invention to make it more user-friendly. After completing their own tests, they plan to begin the process of registering the medical device.
