  • Patent number: 6416471
    Abstract: A system and method for monitoring vital signs and capturing data from a patient remotely using radiotelemetry techniques. The system is characterized by a cordless, disposable sensor band with sensors form measuring full waveform ECG, full waveform respiration, skin temperature, and motion, and transmission circuitry for the detection and transmission of vital signs data of the patient. A small signal transfer unit that can either be worn by the patient, e.g., on his or her belt, or positioned nearby receives data from the sensor band, which it then forwards by e.g., radio transmission to a base station that can be located up to 60 meters away. The base station receives data transmissions from the signal transfer unit and is designed to connect to conventional phone lines for transferring the collected data to a remote monitoring station. The base station may also capture additional clinical data, such as blood pressure data, and to perform data checks.
