    摘要: The invention describes a measuring system for the continuous non-invasive determination of blood pressure at one or more fingers. The fingers chosen for measurement and the adjacent parts of the palm rest on a supporting surface of a housing, which has the shape of a computer mouse. Inside the housing of the “CNAP Mouse”, i.e. underneath the supporting surface for the hand, the pressure generating system is located. The finger sensors are mounted on the supporting surface for the hand. The forearm and the back of the hand are left free and may be used to place intra-venous or intra-arterial access elements. Since the hand will rest on the supporting surface motion artefacts are largely avoided. Tilting or turning of the sensors is hardly possible since the fit of the sensors and thus the coupling of light and pressure are optimized.

    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: A system and method of digital control for a blood pressure measurement system is provided. According to at least one embodiment, a photo-plethysmographic (PPG) system produces a frequency signal that corresponds to the measured light in the PPG system. Such light may be indicative of blood volume in a vein or artery. The frequency signal may be used to control one or more pressure valves of the system in order to measure blood pressure and hold the frequency signal constant.

    摘要: A system and method of enhancing a blood pressure signal is disclosed. The volume of an artery in a finger is measured by a photo-plesthysmographic (PPG) system, which produces a PPG signal. This PPG system is placed inside a cuff, and the cuff pressure is controlled by the PPG signal. The portion or component of the PPG signal having a frequency higher than a predefined threshold frequency is then modified or enhanced, such as by multiplying the high frequency component by a calibration factor. A blood pressure signal is then calculated using the cuff pressure and the modified PPG signal. A blood pressure contour curve may then be generated, and a variety of parameters may be calculated using the curve.

    摘要: The invention relates to a method and a measuring device for continuously non-invasively determining at least one cardiovascular parameter, preferably the arterial blood pressure, at an extremity containing an artery, the measuring device comprising a receiving element that can be attached to the extremity and is suited to at least partly surround the extremity, and comprising a flexible bubble which is supported on the receiving element, acts on the extremity and is filled with a fluid. According to the invention, an actuator which is suited to vary the pressure in the flexible bubble is placed in or on the receiving element, and the flexible bubble includes a pressure sensor which is in contact with the fluid in the flexible bubble and which is suited to continuously measure the absolute pressure value. The measuring device further comprises a unit suited to measure the pulsations generated by the volume flow in the artery, and a control unit having two different modes of operation, i.e. a measuring phase and an interpolation phase.
