Abstract: A device is provided for monitoring patients, which is used to detect and process physiological data of a patient, which are measured by sensors. To make possible the most flexible use possible in patient monitoring, especially the connection of additional special sensors (2) and to ensure simple handling of the device even in the case of transportation, the patient monitoring device has a transportable terminal (8), which has connections (18) for connection to sensors (2) for measuring physiological parameters of the patient and signal processing devices (31, 23, 24, 25) for receiving and processing the sensor signals received, and is provided with a network adapter (26) for forwarding the processed sensor data to a stationary medical workplace (14) with display and alarm devices, as well as one or more expansion modules (9) for the connection of additional desired sensors (2).
