Abstract
This paper presents construction, operating principle and initial study of new device for measurement and recording of arterial blood pressure, created at Wroclaw University of Science and Technology. This device is equipped with a pneumatic pressure sensor based on the pneumatic nozzle flapper amplifier principle. During the measurement sensor is applied to the patient’s body, where the pulse is easily palpable. After that, sensor is gradually pressed against to the artery, in order to record peak amplitude. Maximum value of this amplitude corresponds to the real blood pressure waveform. This device was validated according to „International Protocol revision 2010 for the validation of blood pressure measuring devices in adults”.
Highlights
Nowadays blood pressure measurement is one of the most commonly used medical examination
There is a wide range of purchasable commercial apparatus
Among blood pressure measurement apparatus one can find sphygmomanometers. They use aneroid mechanism which displays pressure value taken on the cuff of the examined person as indication of an needle of a manometer mechanism which is scaled in millimeters of mercury
Summary
Nowadays blood pressure measurement is one of the most commonly used medical examination. Among blood pressure measurement apparatus one can find sphygmomanometers They use aneroid mechanism which displays pressure value taken on the cuff of the examined person as indication of an needle of a manometer mechanism which is scaled in millimeters of mercury. They are commonly used by physicians there are models accessible for household use. To the group of electronic blood pressure apparatus belong Hi-End class manual pressure meters. The pressure value in the cuff is displayed on the electronic display
