Injection of magnetizable fluid could extend trauma patients’ survival time

Posted by in category: biotech/medical

Inspired by their use in mechanical systems, Massachusetts Institute of Technology researchers are testing a magnetically-actuated fluidic valve to use in trauma patients suffering from hemorrhage.

Yonatan Tekleab and his colleagues will explain how the valve works at the American Physical Society’s Division of Fluid Dynamics 72nd Annual Meeting on Nov. 25 at the Washington State Convention Center in Seattle. The talk is part of a larger session on biological dynamics for medical devices.

Approximately 80% of trauma related deaths after the first hour of admission to the hospital are due to hemorrhagic shock. Tekleab said their system of an injectable magnetorheological suspension and externally placed small magnets would be able to significantly reduce bleeding before the patient is transported to the hospital.
