Objective To realize remote wireless data transmission in mobile monitoring terminal of pre-hospital first aid so as to enhance the effect of pre-hospital aid, guarantee the reliability and real-time state of data transmission in mobile monitoring terminal of pre-hospital first aid. Methods The software and hardware of the mobile monitoring terminal of prehospital first aid were designed .Then, according to the specialty of the data transmission and requirements of the bandwidth, the choice of wireless network and the transport layer protocol of data transmission were analyzed, and the technology approach fitting for the system were proposed. The protocols selected were PPP and TCP/IP based on μC/OS-Ⅱ . Results Application tests showed that this approach could satisfy system＇s requirement. It could transmit patient＇s vital signs parameters to hospital＇s monitoring equipment exactly in real-time during pre-hospital first aid. Conclusion This design creates the condition for remote hospital guide, resources planning of patient＇s admission and analysis of illness state, which is feasible for application.
