SYSTEM AND METHOD FOR MEASURING ARTERIAL PRESSURE BY ITS EFFECTS
First Claim
1. An arterial pressure measurement system using an indirect method, wherein the system comprises:
- a device applying an external contact force to a measurable artery;
an arterial expression sensor recording the expression produced by blood flow and arterial wall before, during and after receiving an external contact force through the device applying an external contact force, during arterial obliteration process;
a measuring and detection device that, based on the values recorded by both of the abovementioned devices, determines arterial cycle systolic and diastolic periods and therefore measures systolic and diastolic arterial pressure by detecting or not arterial expressions during the arterial cycle corresponding period through the arterial expression sensor and equaling the external contact force applied on the 1a measurable artery to the force required to occlude the same in the corresponding period.

Abstract
The system and method for measuring arterial pressure by its effects consists of a six-stage procedure and three devices; the procedure to indirectly measure diastolic arterial pressure controls the tasks of a first device applying a measured gradual external contact force, a second sensor device of arterial that records arterial expression, and a third device which is a device to measure and detect the arterial cycle diastolic and systolic period in order to provide the diastolic arterial pressure value using an indirect method. Additionally, systolic arterial pressure is measured with no overpressure due to heartbeats produced after arterial occlusion.

21. Method to measure arterial pressure by obliteration, wherein the method comprises the following stages:
-
i. obtaining an arterial cycle by differentiating the systolic and diastolic period; ii. applying an external force on the artery and recording the arterial expression from every period; iii. increasing the external force applied until equaling it to the artery pressure in the arterial cycle period to be measured; and vi. measuring the target blood pressure within the target arterial cycle. - View Dependent Claims (23, 24, 25, 26, 27, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42)
