The system contains a number of monitoring devices, such as bedside units for monitoring parameters of patients, and a central station in star connection. Each monitoring device contains a signal generator and a display device for the display of monitored parameters. The central station contains a central display device and a central multiplexer. The multiplexer has a separate signal input for receiving the output signals of each signal generator, and a first and second number of multiplexer outputs. The output signals of the signal generators each contain undelayed and delayed signal data. The first multiplexer outputs can be connected to the central display device. Thereby, the undelayed signal data contained in the output signals of selected monitoring devices can be displayed in the central station. These signal data represent all parameters monitored by the selected device. The second multiplexer outputs are connected to an intermediate memory for transfer of the delayed signal data of all signal generators thereto. The delayed data stored in the memory can be transmitted in any signal combination for display as a mixed image on the central display device. Thereby, parameters stemming from different monitoring devices can be displayed simultaneously on the central display device.

A system containing a predetermined number of monitoring devices and at least one central station having a central display device, each monitoring device having at least one signal generator, whose output signals can be displayed on a display device associated therewith as a specific image of the monitoring device, and said system further containing a selecting device for connecting said central station to the signal generator of a preselected one of said monitoring devices in such a way that said central station can receive output signals from the signal generator of said preselected one of said monitoring devices for display on said central display device, characterized in that said selecting device comprises (a) a central multiplexer which is connected between said signal generators of said monitoring devices and said central display device of said central station, said multiplexer having a separate signal input for each output signal of said signal generators and having a first and second number of outputs, said first number of multiplexer outputs being connectible to said central display device; (b) an intermediate memory having its signal input connected to said second number of multiplexer outputs and having its signal output connectible to said central display device; and (c) a control unit for controlling said multiplexer in such a way that in a time multiplexing sequence said multiplexer supplies to said first number of multiplexer outputs undelayed signal data which originate from the signal generator of a single one of said monitoring devices, while said multiplexer supplies to said second number of outputs delayed signal data of all said signal generators, whereby said delayed data are stored in said intermediate memory for being called from there in any signal combination for the purpose of display as a mixed image on said central display device.
