Problems solved by technology

Like the above method, this method does not determine whether the blood pressure measurement data properly and accurately reflects the subject's condition, and is not affected by phenomena such as the white coat effect, but only controls the blood pressure measurement according to certain changes in physiological indicators

Embodiment Construction

[0029] The "DC component" of a plurality of data used in the specification and appended claims refers to the average value of the data. The "AC component" of a sequence of initial data refers to a sequence of calculated data, each of which is an initial data minus the DC component of the sequence of initial data.

[0030]If a single pressure sensor is used to search for an artery on the skin, it is necessary to fine-tune the position of the sensor to maintain a preset compression pressure on the skin from the sensor. The curvature and unevenness of the human skin surface necessitates that the pressure sensor must test multiple subtle locations to verify that the desired compaction pressure is being applied, thus greatly increasing the search time. The present invention reduces the search time by dividing the search into a first stage and a second stage, the first stage is to determine a search area by non-contact optical search in order to roughly determine the position of the...

Abstract

The invention discloses a system for measuring blood pressure by using psychological state verification. According to one embodiment, the position of an artery on a human's skin is determined, and a tension pressure sensor is positioned on the position of the artery for measuring blood pressure so as to obtain pressure pulse data of an examination object. When in operation according to the embodiment, a measuring logic of a measuring verification system can uses the pressure pulse data to extract blood pressure data, heart rate data, blood pressure changing data, and heat rate changing data. The aforementioned data can be used to identify whether the blood pressure measuring appropriately and accurately reflect the conditions of the examination object.

Description

technical field [0001] The present invention relates to blood pressure measurement, and more particularly to blood pressure measurement using mental state verification. Background technique [0002] Tonometry blood pressure measurement is a non-invasive method that continuously monitors blood pressure (BP) and obtains additional cardiovascular parameters such as degree of arterial stiffness, cardiac output, and stroke volume. Before such measurements can be made, a precise location of the artery needs to be found on the human skin. [0003] As in US8597195 a single pressure sensor is used on the skin to search for the arterial location. During the search, the compressive pressure the sensor exerts on the skin needs to remain constant. However, since the surface being measured is curved and uneven, such as a human wrist, the sensor needs to precisely and dynamically adjust its position to maintain a constant compression pressure during the search. This requires a long sear...
