An electronic manometer for blood-pressure measurement.
This article reports the development of an electronic manometer for use in the measurement of blood pressure. It is intended to act as a replacement gauge for the mercury and aneroid manometers used in conventional sphygmomanometers. It measures pressure in the range 0-300 mm Hg (0-40 kPa) with a resolution of 1 mm Hg (0.13 kPa) and an accuracy of +/- 1 mm Hg (+/- 0.13 kPa) which is displayed on a liquid crystal display. It operates from a 9 V PP3 battery over a temperature range of 10-50 degrees C.
