A sphygmomanometer of the aneroid gauge type having bellows connected through gears to rotate a shaft, and a pointer mounted on the shaft and movable over a dial to indicate pressure, includes recording means manually actuable to temporarily mark the systolic and diastolic pressures. The recording means has a two layer adhesion marking means attached to the dial and a stylus carried by the shaft in registry with the pointer, and movable to impress a mark upon the adhesion marking means. A separator is provided to detach the two layers to erase the earlier marks when the sphygmomanometer is again used.
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. A user may either manually preset each of the indicators to respective positions corresponding to predetermined medically-established pressure norms for subsequent comparison purposes during the blood pressure measurement, or the user may manually set each of the indicators to its respective pressure measuring position, as observed during the blood pressure measurement for subsequent leisurely recordation.
A system including manometer, cuff, inflator, and stethoscope wherein the manometer has manually-operable "drop-off" pointers. Using the stethoscope, an observer operates the drop-off pointers in succession upon aurally detecting systole and diastole, respectively. The bleed of pressure from the cuff is regulated so that the cuff pressure drops according to a predetermined schedule. Manual operation of the drop-off pointers is caused to reduce the resistance to air flow from said cuff.
A sphygpressure graph of the aneroid gauge type including a housing, connected with a sphygmocuff, supporting a series of telescoping tubes, connected in right angular relation, and a stylus, mounted on the endmost tube, movable over a chart to scribe the blood pressures. A ratchet and pawl arrangement engaging the telescoping tubes prevents reciprocating action of pulse pressure moving the stylus in a to and fro movement transversely over a graph paper but records the pulse by longitudinally scribing a graph paper during release of pressure from the sphygmocuff.
