ABSTRACT:
Apparatus and a method for detecting Korotkoff sounds using a pair of microphones carried by an inflatable cuff adapted to be wrapped around a limb of a patient whose blood pressure is to be determined. A Korotkoff sound is first sensed by one of the microphones to produce a first signal which is coupled to a delay unit which has an output signal delayed by a certain time interval, such as 12 millisecond. At the end of this interval, a window is opened. The same Korotkoff sound is later sensed by the second microphone whose output signal is applied to the window and passes through the window so long as it is open. The output signal then actuates a recorder, such as an oscillograph.
