Arterial blood pressure measuring device for e.g. medical and biological research, has logic device to measure periodical difference between signals detected by pressure sensors and not amplitude of signals, for determining blood pressure

摘要

The device has proximal and distal pressure sensors (64, 68) arranged along a limb of a body to detect pulse signals in the limb. A logic device measures only the periodical difference between the detected signals and not the amplitude of signals, to determine systolic, diastolic and/or average blood pressure. A pressure device is designed to change radial expansion of a blood vessel through the increase in pressure. Independent claims are also included for the following: (A) a method of providing a measuring device that measures the blood pressure in a blood vessel (B) a method of measuring blood pressure in a blood vessel (C) a computer program product for measuring blood pressure in a blood vessel.
