2 results about "Traumatic Hemorrhage" patented technology

This invention belongs to the fields of biomedical materials, flexible electronic devices, and trauma emergency treatment technology, specifically relating to a wireless closed-loop thermal hemostasis system, its preparation method, and its application. This invention utilizes dopamine-modified chitosan to prepare a porous chitosan gel, and introduces a conductive phase into the gel to prepare a composite conductive cryogel. This composite conductive cryogel is connected to a flexible circuit, a temperature sensing array, a flexible heating unit, and a wireless PCB control module to prepare a wireless closed-loop thermal hemostasis system. When used in traumatic massive hemorrhage, the cryogel exhibits a volume-dependent resistance change after absorbing blood. The system utilizes this resistance change to achieve real-time monitoring of the bleeding, hemostasis, and rebleeding processes. The flexible heating unit is controlled via temperature array feedback to rapidly raise the local temperature of the wound within a safe range to the procoagulant zone, thereby achieving automatically triggered and terminated thermal-assisted hemostasis.

Provided herein are adjustable internal tourniquet device and system having an inflatable segmented balloon configured to exert pressure on a site of injury. Further provided are methods of using the same for controlling traumatic hemorrhage wounds.
