  • Publication number: 20100249617
    Abstract: An apparatus for determining the blood pressure of a patient which allows the patient to first measure his measured blood pressure using a blood pressure measuring device and then, at a later time, estimate his current blood pressure using a blood pressure calculating device that includes a mathematical model for estimating blood pressure based on a current change in blood pressure induced by a heart beat and the previously measured blood pressure. The apparatus includes a transmitter device that detects the presence of a blood pressure calculating device connected to or in proximity of the blood pressure measuring device and transmits the previously measured blood pressure value to the blood pressure calculating device.
