    摘要： A blood pressure measurement device determines an amplitude and a frequency of a voltage applied to a piezoelectric pump, carries out control so that a voltage at the determined amplitude and frequency is applied to the piezoelectric pump, and calculates a blood pressure value based on a detected cuff pressure during inflation when the cuff pressure is increased by the piezoelectric pump. A control frequency at which a pump efficiency of the piezoelectric pump is maximum in the case where the fluid is supplied to the cuff at a required flow rate during inflation using a predetermined voltage as the voltage is determined, and first control that applies a voltage at the amplitude of the predetermined voltage and at the determined control frequency is carried out. The amount of power consumed can be reduced when increasing the cuff pressure for blood pressure measurement using the piezoelectric pump.

    摘要： The present invention provides a technique for continuous measurement of blood pressure based on pulse transit time and which does not require any external calibration. This technique, referred to herein as the ‘Composite Method’, is carried out with a body-worn monitor that measures blood pressure and other vital signs, and wirelessly transmits them to a remote monitor. A network of body-worn sensors, typically placed on the patient's right arm and chest, connect to the body-worn monitor and measure time-dependent ECG, PPG, accelerometer, and pressure waveforms. The disposable sensors can include a cuff that features an inflatable bladder coupled to a pressure sensor, three or more electrical sensors (e.g. electrodes), three or more accelerometers, a temperature sensor, and an optical sensor (e.g., a light source and photodiode) attached to the patient's thumb.

    摘要： A device and method for use in monitoring blood pressure. The device comprises a controller configured to monitor a first blood pressure measurement based on a first blood pressure signal. The controller is configured to initiate acquiring a second blood pressure measurement based on a second blood pressure signal if the first blood pressure measurement exceeds a predetermined threshold. The decision to initiate acquiring the second blood pressure measurement is based on only one blood pressure measurement.

    摘要： Improved apparatus and methods for non-invasively assessing one or more parameters associated with systems such as fluidic circulating systems (e.g., the circulatory system of a living organism). In a first aspect, an improved method of continuously measuring pressure from a compressible vessel is disclosed, wherein a substantially optimal level of compression for the vessel is achieved and maintained using dynamically applied dither perturbations (e.g., modulation) on the various axes associated with the vessel. In a second aspect, an improved apparatus and method are provided for monitoring hemodynamic parameters, such as blood pressure, in a continuous and non-invasive manner while operating under a single unifying scheme. One variant of this scheme using a simulated annealing (SA) type approach to determining and maintaining an optimal operating state.
