Fluid damping device for a compliant system

摘要: Apparatus for removing undesirable resonance in a closed, tubular fluid flow system permitting more accurate transducer measurement of varying pressure within the is disclosed. The apparatus includes compliant air cavity coupled to via small diameter aperture, or passage. an elongated pipe, tube, proximal end which inserted conventional cylindrical sleeve and passage coupling system. A plurality such elogated tubes, each having predetermined length thus size, are provided selective insertion providing with fixed series hydraulic resistance incrementally variable parallel capacitance matching impedance tubes may be color-coded facilitate proper tube selection optimum suppression associated improved frequency response. present invention particularly adapted use catheter-tubing-transducer as used electromanometry systems permits hemodynamic accurately measured recorded.
