Patent ID: 8016765

Claim:
A blood pressure measuring device which comprises, in a single unit, a traditional manual sphygmomanometer comprising: a connector port for connection with a subject limb compression cuff, a totally mechanical cuff pressure sensing and indicating mechanism comprising an aneroid pressure sensing mechanism connected to a rotationally movable indicator needle which rotates when the system is pressurized and indicates cuff pressure by its angular position over a pressure scale positioned behind said indicator needle, the totally mechanical and manual sphygmomanometer further comprising a manual inflation bulb for pressurizing said compression cuff, and a manual deflation valve for releasing cuff pressure during the totally manual blood pressure measurement process, a manual blood pressure measuring unit also containing within its enclosure, an electronic blood pressure measuring and monitoring device capable of totally electronic sensing the cuff pressure and small pressure variations in a blood pressure cuff at each cuff pressure during deflation of the cuff by the electrical deflation valve mounted within the enclosure, said cuff pressure values and pressure oscillation values being acquired by and interpreted by a microprocessor mounted within the single enclosure to estimate a subject's blood pressure and heart rate and indicate said blood pressure and heart rate by lighting appropriate LEDs positioned on the same scale as that used for manual indication of cuff pressure, said electronic blood pressure measuring and monitoring device being powered by batteries which are also enclosed within the enclosure.
