Abstract
A blood pressure measuring procedure which can be performed by the subject employing a manually inflatable cuff and associated microphone, a measuring circuit responsive to signals having the form of Korotkoff sounds, a dual-indicator manometer having two individually controllable indicators, a control circuit for controlling the operation of the indicators, and a switch switchable between a pumping position in which it permits the cuff to be manually inflated and releases the indicators to respond to the cuff pressure and a measuring position in which the cuff pressure gradually decreases, one indicator is locked in its present position at the onset of Korotkoff sound signals and the other indicator is locked in its present position upon termination of Korotkoff sound signals. The subject places the cuff in position, moves the switch to its pumping position, inflates the cuff to a pressure above his systolic pressure, and then moves the switch to its measuring position.
