When first responders found the victim slicing in the accident, one of their main goals was to stop the bleeding,media New Atlas reported. By injecting patients with magnetic fluids, they may one day do this more effectively than ever before.
The magnetic liquid was created by a team at the Massachusetts Institute of Technology led by Yonatan Tekleab and contains tiny magnetic particles called magnetic fluid.
The team’s idea was to attach two small but strong magnets to the skin on either side of the scratch wound and then inject the suspension directly into the blood stream upstream of the wound. As the fluid is then brought into the magnetic field between the two magnets, when the particles stop flowing, the fluid solidifies immediately, greatly reducing or even stopping blood flow.
This will be a temporary measure designed to stabilize patients until they are taken to hospital. There, the magnetized blockage is removed and the wound is closed. The system does not address internal damage, but it can still save lives.
“We hope to extend the patient’s survival time by at least 30 minutes by preserving the blood to make them more stable when they reach the trauma center,” SaysTekleab said. Studies have shown that reducing blood loss has an important impact on survival rates. “
Scientists presented their findings Monday at the 72nd annual meeting of the American Physical Society’s Fluid Dynamics Branch in Seattle.
