Abstract
Abstract A sphygmomanometer for use with a pressurizable, bloodrestricting sleeve has a cylindrical housing comprising a core formed with a lateral hollow and an elastic skin stretched over the core spanning the hollow to form a hand-actuatable pump for pressurizing the sleeve. A short-interval timer (clock) and a pressure indicator responsive to pressure in the sleeve are mounted on one end of the housing and each has a scale on a common dial plate. Turning a rotatable control ring surrounding the housing in one sense actuates a valve for bleeding the sleeve to measure blood pressure, and turning it in the other sense starts the timer for measurement of pulse rate.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
111 words
A sphygmomanometer comprising, in combination, a blood-flow-restricting sleeve; pump means for pressurizing said sleeve; an elongated housing receiving said pump means; meter means on an end of said housing having a blood pressure indicator connected with said sleeve and an elapsed-time indicator including a winding mechanism having an actuating arm; and control means on said housing for triggering operation of said elapsed-time indicator, said control means including a control ring rotatably mounted on and surrounding said housing for rotation about the longitudinal axis thereof in a plane perpendicular to said axis between said pump means and said meter means and actuating means operatively connecting said control ring with said actuating arm.
Claim 2
Dependent Claim
111 words
A sphygmomanometer comprising, in combination, a blood-flow-restricting sleeve; pump means for pressurizing said sleeve; an elongated housing receiving said pump means; meter means on an end of said housing having a blood pressure indicator connected with said sleeve and an elapsed-time indicator including a winding mechanism having an actuating arm; and control means on said housing for triggering operation of said elapsed-time indicator, said control means including a control ring rotatably mounted on and surrounding said housing for rotation about the longitudinal axis thereof in a plane perpendicular to said axis between said pump means and said meter means and actuating means operatively connecting said control ring with said actuating arm.
Claim 3
Dependent Claim
131 words
A sphygmomanometer comprising, in combination, a blood-flow-restricting sleeve; pump means for pressurizing said sleeve; an elongated housing; meter means on an end of said housing having a blood pressure indicator connected with said sleeve and an elapsed-time indicator including a winding mechanism having an actuating arm; and control means on said housing for triggering operation of said elapsed-time indicator, said control means including a control ring rotatably mounted on said housing for rotation about the longitudinal axis thereof and actuating means operatively connecting said control ring with said actuating arm said control ring being provided with an engaging formation and said actuating means including a longitudinally extending pivotal elongated member having one end engaging said formation and another end engaging said actuating arm for displacement of the latter by said ring.
Claim 4
Dependent Claim
131 words
A sphygmomanometer comprising, in combination, a blood-flow-restricting sleeve; pump means for pressurizing said sleeve; an elongated housing; meter means on an end of said housing having a blood pressure indicator connected with said sleeve and an elapsed-time indicator including a winding mechanism having an actuating arm; and control means on said housing for triggering operation of said elapsed-time indicator, said control means including a control ring rotatably mounted on said housing for rotation about the longitudinal axis thereof and actuating means operatively connecting said control ring with said actuating arm said control ring being provided with an engaging formation and said actuating means including a longitudinally extending pivotal elongated member having one end engaging said formation and another end engaging said actuating arm for displacement of the latter by said ring.
Claim 5
Dependent Claim
17 words
The sphygmomanometer defined in claim 2 wherein said formation is a longitudinally raised portion on said ring.
Claim 6
Dependent Claim
33 words
The sphygmomanometer defined in claim 2, further comprising means on said housing pivotally supporting said member for swinging movement about an axis extending substantially parallel to the major dimension of the elongated member.
Claim 7
Dependent Claim
13 words
The sphygmomanometer defined in claim 2 wherein said control ring surrounds said housing.
Claim 8
Dependent Claim
40 words
The sphygmomanometer defined in claim 2, further comprising a dial plate having a pressure scale in the path of said pressure indicator and an elapsed-time scale in the path of said elapsed-time indicator, and a window for viewing said scales.
