OREANDA-NEWS  Employees of the NUST MISIS Biomedical Engineering Center have created the first "tissue gun" in Russia that can stop bleeding and start regenerative processes in cases of mild and moderate injuries. The device is designed to work in military field conditions and in an emergency zone. About this "Newspaper.Ru" was told in NUST MISIS.

With the help of a gun, a so-called barrier effect is created on the skin due to the parallel high-precision supply of painkillers, hemostatic, antibacterial and other substances to the wound. When crosslinking, the bioactive material creates a film on the wound, preventing infection and creating favorable conditions for accelerated healing.

"Before work, two standard syringes with a volume of 20 ml are filled with biopolymers and medical preparations. A third syringe is connected through a special port and the device is refilled with a crosslinking agent, then the refueling syringe is turned off. When the trigger is pulled, the ultrasound system simultaneously collects all the components in the printing area, thereby forming a polymer cross–linked biomaterial capable of stopping bleeding and accelerating tissue regeneration," he told the newspaper.Ru" author of the development Timur Aidemir, engineer of the NUST MISIS Biomedical Engineering Center.

Unlike existing world analogues, the developed device is completely autonomous and is powered by built-in rechargeable batteries that can be charged via a USB port.

According to the developers, the cost of the device is low. It is noted that if the gun is not printed on a 3D printer, but poured from plastic, then it will become even cheaper. If necessary, a 3D printer can be used to print parts of a "pistol" in a war zone.

Scientists have already conducted a series of studies on the basis of the N.N. Blokhin Oncology Research Center. The results showed that when using a two-component hydrogel, faster healing of a burn wound was observed in experiments on laboratory mice. Now the study of tissues after healing is being carried out.
