Patent attributes
The present invention relates generally to a non-invasive device for monitoring blood pressure using principle of applanation tonometry. A novel device for measuring pressure pulse comprises a differential screw mechanism, a sensor module connected to the screw mechanism, and an overall enclosure housing the sensor module and the differential screw mechanism in one unit. A pair of straps is attached to the enclosure, wherein said straps as a flex lock brace through a hinge to change the angle of extension of the wrist as required. The multi component sensor module comprises of a snap-fit enclosure, which houses a tactile-based force sensitive resistor, and a mechanism to transmit the forces from the artery. The force transmission mechanism comprises of a gel layer and a gel head. The differential screw mechanism ensures precise hold down pressure in multiple stages via screwing and unscrewing steps to accurately measure the blood pressure.
