Abstract:
A sphygmomanometer comprising, in combination: (a) an arm cuff with an inflatable air bladder; (b) a pumping device for inflating the air bladder; (c) an air outlet valve for deflating the air bladder; (d) an air pressure transducer operative to receive the pressure in the air bladder and to produce an electrical signal representing said pressure; (e) a manually operated switch for generating systolic and diastolic interrupt signals; (f) a first electronic display for displaying said pressure in the air bladder in the form of a bar graph, said first display having a plurality of hatch marks and numbers showing the level of pressure to be indicated by the bar graph and simulating a mercury column pressure gauge as used in a mercury sphygmomanometer; (g) a second electronic display for displaying systolic and diastolic pressures; and (h) an electrical circuit, connected to said pressure transducer and to said switch, for controlling said first and second display.
