Patent ID: 7598878

Claim:
A system for measuring at least one physiological parameter of a subject, comprising: (a) a fastening article for being fastened to the wrist of a first hand of the subject; (b) a measuring device for measuring at least one physiological parameter of the subject, said measuring device configured to be attached to the wrist by said fastening article; (c) three separate conductive areas on a surface of said measuring device, said conductive areas configured to measure electrical activity of the subject, said three conductive areas arranged in one of the following configurations: (i) a first conductive area configured to be in contact with at least a portion of the wrist, second and third conductive areas configured to be touched by two fingers of a second hand of the subject; (ii) first and second conductive areas configured to be in contact with at least a portion of the first hand and a third conductive area configured to be touched by a second hand of the subject; (d) a processor for continuously receiving a signal from said measuring device and for continuously converting said at least one measurement to form medical information; (e) a communication unit configured for at least continuously receiving said medical information from said processor and configured for at least continuously transmitting said medical information; and (f) a mobile gateway device configured for at least receiving said medical information from said communication unit and for at least transmitting said medical information to a remote location; wherein said system is configured to be carried by the subject; wherein said physiological parameter includes an electrocardiogram (ECG) signal; and whereby said ECG signal is extracted from said three conductive areas by using the signal of one conductive area as a reference and amplifying the differential voltage between the other two conductive areas.
