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.

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： A measuring device to measure vascular function of an artery includes a cuff that is attachable to a specified part of a body to constrict the artery, a pulse wave amplitude calculating device that calculates an amplitude of a pulse wave that is synchronous with a heartbeat and is based on a change in a volume of the artery, and an inference device that infers a pressure-to-volume characteristic for the artery based on the amplitude of the pulse wave and a corresponding pressure. A blood pressure meter incorporating the measuring device uses a measure of the vascular function to determine a degree of sclerosis in the artery.

摘要： The amplitude of a pulse wave that appears in a form superimposed upon cuff pressure is detected every beat of a heartbeat in synchronism with the beat not only in the course of depressurization but also in the course of pressurization. The maximum value Amaxi of the pulse-wave amplitude in the course of pressurization is multiplied by a prescribed coefficient to decide a threshold value TH. The threshold value TH is calculated as a value equivalent to a pulse-wave amplitude corresponding to systolic pressure that would be determined in the course of depressurization. After the cuff is pressurized to the target pressure, a transition is made to the depressurizing process. It is judged that cuff pressurization is inadequate if the initial pulse-wave amplitude in the course of depressurization is greater than the threshold value TH. Thus, whether or not cuff pressurization is inadequate can be judged appropriately at all times without any influence due to personal differences or physical condition.
摘要翻译：不仅在减压过程中，而且在加压过程中，与搏动同步地，与心跳同步地检测以叠加袖带压力的形式出现的脉搏波的振幅。将加压过程中的脉搏波振幅的最大值Amaxi乘以规定的系数，以决定阈值TH。阈值TH被计算为与在减压过程中确定的收缩压对应的脉搏波振幅相当的值。在袖带被加压到目标压力之后，对减压过程进行转变。如果在减压过程中的初始脉搏波振幅大于阈值TH，则认为袖带加压不足。因此，无论袖口加压不适当，都可以随时判断，不会由于个人差异或身体状况而产生任何影响。

摘要： An electronic blood pressure meter which determines a systolic blood pressure value and a diastolic blood pressure value by detecting a sharpest positive peak and a sharpest negative peak of a pulse wave, respectively, which may be extracted from a cuff pressure. The sharpest peaks may be detected by finding the points of intersection of the pulse wave level with a certain threshold level and finding the shortest time interval between adjacent points of intersection interposing a peak therebetween. Since the principle of measurement is exact and can be implemented as a relatively simple algorithm, accurate measurement is possible substantially without any exception.

摘要： An electronic blood pressure meter is disclosed which measures diastolic blood pressure. The blood pressure meter includes a cuff, a device for pressurizing and a device for depressurizing the cuff, and a device for detecting pressure in the cuff over time. A device is provided for detecting pulse waves, preferably in the form of an infrared light source and a reflected light detector. Processing circuitry is provided which detects either appearance or disappearance of a flat portion in the pulse wave by differentiating the pulse wave, measuring successive durations of time during which the differentiated pulse wave is between predetermined threshold values, and determining the moment at which the durations of time become less than a predetermined amount. The diastolic blood pressure value is then determined as the measured pressure in the cuff at the moment the flat portion of the pulse wave has appeared or disappeared.
