摘要： Provided are an apparatus and method of detecting a pulse wave at the certain position of an artery. A pressure sensor array has a pressurization surface on which plural pressure sensors are disposed in a direction intersecting with an artery. The pressurization surface, when a pulse wave is detected, is pressed against a surface of a living human body by a cuff pressure in a pressurization cuff. CPU, when a pulse wave is detected, inputs voltage signals indicating pressure information from the plural pressure sensors simultaneously along with the time axis. CPU extracts the DC component indicating a pressure component caused by a hard member from a voltage signal to specify the pressure sensor located above the hard member from the extracted DC component. The pressure sensors left after the specified pressure sensor located above the hard member among the plural pressure sensors are selected as candidates of the pressure sensor located above the artery to detect a pulse wave generated in the artery based on pressure information outputted from the selected pressure sensors.

摘要： A pulse wave measuring apparatus obtains the N-th derivative of a measured pulse waveform. The pulse waveform is classified into waveforms α-δ in accordance with the presence/absence of a shoulder (inflection point) at a rising phase of a pulse waveform of one beat, and also in accordance with the presence/absence of a shoulder in a falling phase. In each classified waveform, each calculated characteristic point of the N-th derivative corresponds to a traveling wave or reflected wave. The pulse wave measuring apparatus can calculate an AI value or the like that is the characteristic value of a pulse wave using such characteristic points and calculation equation of each waveform.

摘要： A pulse wave measuring apparatus extracts a direct current component from a pressure value obtained from a sensor pressure, and defines the pressurization force of the cuff as the optimum pressurization force when that direct current component is stable. Following determination of the optimum pressurization force, the pulse wave measuring apparatus monitors whether the direct current component obtained from the pressure sensor is optimum or not, and adjusts the pressure, when not. By determining the rising sharpness of the peak and waveform distortion in the sphygmographic waveform, determination is made whether the pressurization force of the cuff is appropriate or not to carry out further adjustment of pressure, as necessary.

摘要： A sensor is pressurized adjustably against a patient's wrist and detects a pressurized pulse wave of a radial artery in a noninvasive manner so as to measure blood pressure on an arm band wound around the patient's predetermined portion. A CPU calculates indices reflecting a reflecting phenomenon of a pulse wave as organism information different from the blood pressure based on the detected pulse waveform, and relates the measured blood pressure value with calculated indices so as to display them on an indicator. A doctor checks displayed contents so as to clearly understand a state of a circulatory system represented by a correlation between the patient's blood pressure and the indices so as to be capable of obtaining information which supports a diagnosis and prescription quickly.

摘要： An electronic sphygmomanometer starts from pressurization and then enters a decompression process. When measurement of blood pressure starts, only a standard pressure release rate voltage is applied to a valve from a standard pressure release rate voltage supply circuit through a decompression control circuit. The valve allows air to be discharged slowly at the standard pressure release rate. If the pressure release rate should be increased for decompression, target pressure release rate acceleration value voltage according to the position of a dial is supplied from an external control signal supply unit. The standard pressure release rate voltage is added to the target voltage and the resultant voltage is supplied to the valve via the decompression control circuit. The valve increases the pressure release rate by the amount corresponding to the external control signal voltage. In this case, even if the dial is returned to zero position, the pressure release rate never falls below the standard pressure release rate.
