Joseph S Eckerle: Blood pressure monitoring method and apparatus. SRI International, Victor R Beckman, January 24, 1989: US04799491 (93 worldwide citation)

Intraarterial blood pressure is measured noninvasively by an electromechanical transducer. The correct hold-down force to be applied to the transducer for obtaining accurate blood pressure measurements is determined by obtaining a set of at least one of the diastolic pressure, systolic pressure, and ...

Joseph S Eckerle: Blood pressure monitoring method and apparatus. SRI International, Victor R Beckman, February 7, 1989: US04802488 (76 worldwide citation)

Intraarterial blood pressure is measured noninvasively by an electromechanical transducer (22) that includes an array of transducer elements (22-1 through 22-19). The transducer extends across an artery (24) with transducer elements at the ends of the array extending beyond opposite edges of the art ...

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. ...

A blood pressure measurement system is configured to perform a calibration automatically when a calibration condition is satisfied. The calibration condition is based upon one or more parameters of pulse waves of a subject. The parameters may include pulse wave area; a time difference between systol ...
