Spray-on Powder Stops Life-Threatening Bleeding in One Second
Researchers at KAIST have developed a revolutionary spray-on powder that can stop severe bleeding in approximately one second by instantly forming a strong gel over wounds, even on deep and irregular injuries.
Rapid Hemostasis Technology
A new spray-on powder developed by KAIST can stop life-threatening bleeding in about one second by instantly forming a strong gel over a wound. This innovation represents a major advance in emergency medical technology and trauma care, offering potential life-saving applications in hospitals, military field conditions, and remote locations.
How the Technology Works
The spray-on powder formulation works through a rapid polymerization process that occurs upon contact with bodily fluids. When applied to a bleeding wound, the powder particles react and form an instantaneous, adhesive gel that seals the injury site and controls hemorrhaging. It works on deep and irregular injuries where conventional hemostatic methods may prove ineffective or insufficient.
Medical and Clinical Advantages
The one-second response time is significantly faster than traditional wound management techniques such as tourniquet application, pressure bandages, or conventional hemostatic agents like gauze with clotting factors. This rapid action could be critical in trauma situations where every second matters. The ability to treat irregular and deep wounds expands its applicability beyond simple surface injuries to more complex laceration patterns.
Broader Impact and Deployment
If the technology successfully completes clinical trials, it could be widely deployed in emergency departments, operating rooms, and ambulance services worldwide. Military medical personnel have shown particular interest in the technology for battlefield trauma care. The KAIST team is now working on optimizing the formulation for various wound types and testing its efficacy in diverse clinical scenarios to ensure safety and reliability across different patient populations.
