Abstract

Abstract 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.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 124 words
A recording sphygmamanometer comprising a gauge with a shaft and a pointer carried by said shaft over a dial, characterized by recording means including marking means adjacent said dial, a movable stylus for impressing marks in said marking means, and erasure means for removing said marks, said stylus being carried by said shaft in registry with said pointer, said marking means comprising two annular layers of material closely spaced from one another and adapted to be temporarily adhered by said stylus and said erasure means including a movable mount for one of said adherable layers of material, and means for moving said mount relatively to the other of said adherable layers to pull apart the portions of said layers temporarily adhered by said stylus.
Claim 2
Dependent Claim 124 words
A recording sphygmamanometer comprising a gauge with a shaft and a pointer carried by said shaft over a dial, characterized by recording means including marking means adjacent said dial, a movable stylus for impressing marks in said marking means, and erasure means for removing said marks, said stylus being carried by said shaft in registry with said pointer, said marking means comprising two annular layers of material closely spaced from one another and adapted to be temporarily adhered by said stylus and said erasure means including a movable mount for one of said adherable layers of material, and means for moving said mount relatively to the other of said adherable layers to pull apart the portions of said layers temporarily adhered by said stylus.
Claim 3
Dependent Claim 44 words
A recording sphygmomanometer according to claim 1 wherein said layer mount comprises a ring mounted in said gauge for rotation in the plane of said layer, and wherein said moving means is attached to said ring and operable from the exterior of sAid gauge.
Claim 4
Dependent Claim 113 words
A recording sphygmomanometer comprising a gauge with a shaft and a pointer carried by said shaft over a dial, characterized by recording means including marking means adjacent said dial, and a movable stylus for impressing marks in said marking means, said stylus being carried by said shaft in registry with said pointer, and comprising a flexible arm secured to said shaft; a marking member pivotally mounted to said flexible arm; and spring means connecting said marking member to said flexible arm to bias said marking member against one direction of pivoting, said spring means resiliently deforming as said marking member impresses a mark, thereby to cause said marking member to pivot during marking.
Claim 5
Dependent Claim 113 words
A recording sphygmomanometer comprising a gauge with a shaft and a pointer carried by said shaft over a dial, characterized by recording means including marking means adjacent said dial, and a movable stylus for impressing marks in said marking means, said stylus being carried by said shaft in registry with said pointer, and comprising a flexible arm secured to said shaft; a marking member pivotally mounted to said flexible arm; and spring means connecting said marking member to said flexible arm to bias said marking member against one direction of pivoting, said spring means resiliently deforming as said marking member impresses a mark, thereby to cause said marking member to pivot during marking.
Claim 6
Dependent Claim 27 words
A recording sphygmomanometer according to claim 3 wherein said spring means comprises a leaf spring fixedly secured to said marking member and bearing against said flexible arm.
Claim 7
Dependent Claim 109 words
A recording sphygmomanometer comprising a gauge with a shaft and a pointer carried by said shaft over a dial, characterized by recording means including marking means adjacent said dial, a movable stylus for impressing marks in said marking means, and means for moving said stylus, said stylus being carried by said shaft in registry with said pointer, said moving means being operable from the exterior of said gage and comprising a ring mounted for helical motion about the shaft carrying said stylus, said ring pushing said stylus axially to impress a mark during such motion, and pushbutton means operable from the exterior of said gauge for moving said ring.
Claim 8
Dependent Claim 109 words
A recording sphygmomanometer comprising a gauge with a shaft and a pointer carried by said shaft over a dial, characterized by recording means including marking means adjacent said dial, a movable stylus for impressing marks in said marking means, and means for moving said stylus, said stylus being carried by said shaft in registry with said pointer, said moving means being operable from the exterior of said gage and comprising a ring mounted for helical motion about the shaft carrying said stylus, said ring pushing said stylus axially to impress a mark during such motion, and pushbutton means operable from the exterior of said gauge for moving said ring.
