A new hydrogel developed by the scientists will help tp control internal bleeding. There are many reasons that cause bleeding. It can happen as a result of inflammation, trauma, and tumor conditions. Many people are prone to bleeding in the gastrointestinal tract as a result of illness. There are patients who require constant monitoring of blood flow. This new development could be a perfect way to quickly and effectively block ruptures in diseased vessels.
The new hydrogel proved to be a powerful blocking material that eventually degrades enough to normalize blood flow. There are different methods of stopping bleeding. Traditionally, braided wire of stainless steel or platinum is used.
They are of different lengths and thicknesses and are placed in damaged blood vessels using a special catheter. There are liquid blockers that are injected. But there are many complexities in using these methods. Special equipment is needed for connection, installation, introduction into the body, special training and education of specialists is required.
Liquid agents often ooze during injection, there is a risk that they may not enter the blockage site. Most importantly, none of these methods makes it possible to see the entire procedure using tomography devices. Visualization could make these processes more efficient.
A group of scientists from the Terasaki Institute and Mayo Clinic proposed the use of cheap but effective hydrogels to control bleeding. They have excellent biocompatibility, self-healing and shaping ability to blood vessel conditions. To do this, the scientists combined silicate nanoplastic discs with a hydrogel, and mimicked the clotting ability of platelets.
The composite they obtained proved to be very effective in blocking damaged veins and blood vessels. The researchers decided to push the boundaries of their invention and added particles created from a mixture of tantalum hydrogel to the imaging hydrogel. It is a highly biocompatible metal that is completely eliminated from the body.
