  • Continuous non-invasive blood pressure monitoring method and apparatus
    Patent number: 6893401
    Abstract: A non-invasive apparatus and method for monitoring the blood pressure of a subject detects a pulse signal at both a first and second location on the subject's body The elapsed time between the arrival of corresponding points of the pulse signal at the first and second locations is determined. Blood pressure is related to the elapsed time by relationships such as: P=a+b ln(T), where a and b are constants dependent upon the nature of the subject and the signal detecting devices.
    Type: Grant
    Filed: May 15, 2003
    Date of Patent: May 17, 2005
    Assignee: VSM Medtech Ltd.

    Abstract: A non-invasive apparatus and method for monitoring the blood pressure of a subject detects a pulse signal at both a first and second location on the subject's body. The elapsed time between the arrival of corresponding points of the pulse signal at the first and second locations is determined. Blood pressure is related to the elapsed time by relationships such as: P=a+b ln(T) where a and b are constants dependent upon the nature of the subject and the signal detecting devices. The system can be calibrated by measuring a single pair of reference blood pressure and corresponding elapsed time.
