SYSTEM AND METHOD FOR BLOOD PRESSURE MEASUREMENT BY ITS EFFECTS Russian patent published in 2014 - IPC A61B5/22 A61B5/245 

FIELD: medicine.

SUBSTANCE: system for blood pressure measurement with using an indirect method comprises a device for applying an external contact force to the measured artery, a prominent arterial sign detector and a measuring and recording device for deriving systolic and diastolic periods of the arterial cycle from the detector records. The measuring and recording device measures diastolic pressure during the diastolic period, before the artery is completely occluded, and systolic pressure is measured during the systolic period, when the artery is occluded. The detector records the prominent signs before, during and after the external force has been received. While measuring the blood pressure by obliteration, the arterial cycle is received by differentiating the systolic and diastolic periods without involving the blood flow and arterial wall into the external force. The external force is applied to the artery, and the arterial prominent sign is recorded from each period. The external force is prolonged until balanced with the blood pressure during the measured period. The pre-set blood pressure is measured during the pre-set arterial cycle, when the arterial prominent sign disappears during any of the systolic or diastolic periods. When measuring the diastolic blood pressure by a release, the external force is applied to the artery until it has been occluded. The external force is released until balanced with the blood pressure during the diastolic period. The diastolic pressure is measured, while recording the blood prominent sign at the moment of time, when the arterial prominent sign appears from the diastolic period of the arterial cycle.

EFFECT: using the group of inventions enables increasing the blood pressure measurement accuracy with the use of the indirect method.
