Health parameters and video live transmission with data storage on database, in emergency telemedicine

Mobile communication technologies could strongly help in facing health emergency situation. Thanks to wireless communication techniques, real time audio, video, medical parameters transmission and information storage are nowadays possible. Electrocardiogram, blood pressure and other patient's information are sent to a remote hospital/medical database center server. Actions taken by the emergency staff are stored for real time operative-center interaction and for a successive database consultation. The emergency video recording is often useful as legal evidence in case of disputation. In this paper a real time connection telemedical system is described. The system is based on low-cost consumer technologies such as GPRS and WiFi for low-band data/video transmission, H.264 for the real time video stream encoding and database video storage. A relational database has been used for store and query data All system is based on Microsoft .Net technology allowing great portability and stability to overall modules, such as HMI (human machine interface) and multimedia codecs.
