Abstract
This invention is shown with two modes of construction and use. In the first arrangement, there is provided a dual tubular fluid conductor in which the blocking filter is positioned at the entering end of a second fluid conduit leading from a catheter to a transducer. In the second arrangement, the blocking filter is disposed at the fast-flush device and insures an absence of bubbles in a fluid conductor from the device to a transducer. The blocking filter is positioned so as to be in the fluid-conducting path from the patient to a transducer, with this blocking filter of hydrophilic material so that pulse signals sent to and through the fluid conductor connected to the transducer ar not distorted by the presence of air bubbles.
