RESUMO
Objective: To design a clock synchronization system for multi-functional monitor so as to apply objective and accurate technical means to realize automatic synchronization for clock of bedside multi-functional monitor. Methods: The simple network time protocol(SNTP) which was defined in the standard of consistent time(CT) from integrating the healthcare enterprise(IHE) were chosen and clock synchronization source which suited to medical organization were adopted, and all of them were applied to design clock synchronization system based on Windows platform. Results: The clock synchronization system can be integrated to connect with the original monitor system, and 7 central station monitor systems were integrated and connected, and total of 58 multi-functional monitors were joined up. Except manual synchronization mode, both of satellite and internet can achieve real time synchronization of clock for 58 bedside monitors. Conclusion: The clock synchronization system of bedside multi-functional monitor can effectively realize clock synchronization of monitor system, and it can avoid the potential risks caused by time inconsistency. At the same time, it can connect with more emergency equipment to realize clock synchronization.
