Abstract:
A system (1) for patient monitoring comprising:at least one body sensor (2a) for detecting a physiological parameter; p1 at least one body signal processing unit (3; 204, 206) connected with the body sensor (2a) and a therapy device (2; 2â€²) adapted to act one a patient (P); a central monitoring station (1C) being connected to a cellular mobile radiotelephone network (1B) by a terminal unit (11); a portable mobile radio terminal unit (7; 700) which transmits data from the body signal processing unit (3; 204, 206) and the therapy device (2; 2â€²) to the central monitoring station (1C) by the cellular mobile radiotelephone network (1B), a base station co-ordinate memory unit (13) in the central monitoring station (1C) storing base station coordinates of base stations (8.1; 8.2; 8.3) of the cellular mobile radiotelephone network (1B); a rough locator unit (12) in the central monitoring station (1C) for a rough determination of a patient's current location based on rough positioning information obtained from said base station coordinates of a current base station connection of the mobile radio terminal unit (7; 700) in the cellular mobile radiotelephone network (1B); a fine locator unit comprising a direction-finding transmitter (300) in the mobile radio terminal unit (7, 700) emitting a direction-finding signal and a separate, portable direction-finding receiver (310) for fine tracking of said direction-finding signal and fine locating the mobile radiotelephone terminal unit (7, 700) after the rough location determination, wherein the direction-finding transmitter (300) that transmits a direction-finding signal is formed by a transmitter part of the mobile radio terminal unit (7, 700) itself, wherein the direction-finding receiver is formed by a modified standard mobile radio terminal unit (310), and a high-resolution field intensity meter (313) for the direction-finding signal to be received.
