ABSTRACT:
A method and system for monitoring the availability of medical aids for a patient. A first signal transmitter is mounted on the aid for transmitting first electromagnetic signals. A second signal transmitter is worn by the patient and has a warning device for outputting a warning signal which can be perceived by the patient. A receiving unit receives the first electromagnetic signals transmitted by the transmission unit. A control unit actuates the warning device to output the warning signal when the first electromagnetic signal is received and when a predetermined reception strength for the first electromagnetic signal is undershot and when a particular item of information associated with an operative state of the medical aid is transmitted with the first electromagnetic is received.
