Secure Transmission of Pre-clinical Ultrasound Video Data at the Scene of a Mass Casualty Incident

The use of portable ultrasound devices enables a better and immediate diagnostics at the scene of a mass casualty incident. The detection of free fluid in abdomen and thorax is an important indicator for the further treatment. The gained information affects the triage of casualties, the pre-clinical medical attendance and the patient management. The presented article describes an innovative approach to transmit sonographic video streams over wireless networks to a remote hospital, where the medical data is used for diagnostics. For the secure transmission of data a new network unit is designed, which gathers information with regard to the network status and the character of transported data. This "Intelligent Network" is located in the transport layer of the OSI reference model and enables a dynamic interconnection between network and application, provides an interface for functional transparency and the disclosure of parameters and establishes the basis for an universal security system.
