  • Sphygmomanometer gauge and method of use for blood pressure measurement
    Patent number: 4222390
    Abstract: A sphygmomanometer gauge included a stationary dial having graduations indicative of different blood pressure values. A needle is turnable about an axis over the dial in response to changes in air pressure generated in the sphygmomanometer. A pair of adjustable members are mounted on the gauge for turning movement in either circumferential direction about the axis. Each adjustable member has an access portion which extends through the gauge housing to thereby permit independent and manual turning. A systolic indicator and a diastolic indicator are respectively mounted on the adjustable members for turning movement with the latter. Each indicator is operative to simultaneously indicate both a single value and a range of values of blood pressure.
