A hybrid sphygmomanometer comprises:(a) an arm cuff with an inflatable air bladder;(b) a pumping device for inflating the air bladder;(c) a manually controlled air outlet valve for deflating the air bladder;(d) an air pressure transducer operative to receive the pressure in the air bladder of the arm cuff and to produce an electrical signal representing this pressure;(e) a manually operated switch for generating systolic and diastolic interrupt signals;(f) a first electronic display for displaying the instantaneous pressure in the air bladder in the form of a bar graph;(g) a second electronic display for displaying systolic and diastolic pressures; and(h) an electrical circuit connected to the pressure transducer and to the button for controlling said first and second display.The first display, for displaying the instantaneous pressure in the air bladder, is a simulated mercury column. The electrical circuit provides an output of digital signals, representing the systolic and diastolic pressures, for use by a programmed digital computer for storage and processing. It also provides an output of manually or digitally entered patient identification data.
