Except for real time communication betweensickrooms and the nursing station, situations in every sickroom are excepted to be learned conveniently, thus realizingscientific sickroom management of the hospital. Methods The Calling System of Sickbed was designed by usingprogrammable controller instead of singlechip control system. Results The experiment demonstrated that the SickbedCalling System designed by programmable controller was simpler and more popular. Conclusion Calling System of Sickbeddesigned by programmable controller can realize the management of Sickbed Calling System promptly and accurately. It has a bright application future.[Chinese Medical Equipment Journal, 2008, 29( 7) : 21- 22, 25] Key words Sickbed Calling System, PLC, sickro
