| titleOfInvention | Automatic sphygmomanometer |
| abstract | This invention relates to an automatic sphygmomanometer with which the blood pressure of a subject is measured on the basis of the Korotkoff sounds, and which helps to set the ranges where the highest and lowest blood pressures can exist by analyzing changes in pulsation signal amplitude of the detected cuff pressure signal and judge whether or not the blood pressures determined on the basis of the appearance and disappearance of the Korotkoff sounds are contained in these ranges. Preferably, the sphygmomanometer of the invention is provided with two systems of amplifier-filter circuits suitable for the frequency characteristics of the Korotkoff sound signals near the highest and lowest blood pressures and a circuit for discrimination based on a threshold value so as to improve accuracy of judgement of each of the highest and lowest blood pressures. Still preferably, said two systems and the threshold signals are made accessible and controllable from the outside so as to calibrate an electronic sphygmomanometer by using also a stethoscope. |
