    摘要: An intravascular catheter, comprising a hub having a pair of branched tubes mounted thereto apart from each other in the axial direction of the hub, a flexible double-walled tube having an inwardly tapered tip portion and consisting of an inner tube and an outer tube coaxial with the inner tube, and a needle removably inserted into the inner tube of the double walled tube. The base edge of the inner tube is located at an intermediate portion between the positions from which the pair of the branched tubes extend outward so as to enable the inner passageway formed in the inner tube to communicate with one of the branched tubes. The base edge of the outer tube is fixed to the tip of the hub so as to enable the annular passageway formed between the outer wall of the inner tube and the inner wall of the outer tube to communicate with the other branched tube. Further, the inner passageway has an opening at the tapered tip of the double-walled tube and the forward end of the annular passageway communicates with a bore or bores provided at the forward end portion of the outer tube.

    摘要: In a catheter comprising a proximal inner tube having a reinforcing layer applied thereto and a distal inner tube made of a material having different physical properties from those of the proximal inner tube, the proximal and distal inner tubes are axially integrally connected such that the outer surface of the proximal inner tube is substantially smooth and continuous to that of the distal inner tube, and a sheath continuously covers the proximal and distal inner tubes. The catheter is produced by axially integrally joining proximal and distal inner tubes and continuously covering the interconnected tubes with a sheath.

    摘要: An apparatus for measuring cardiac output includes a first system for obtaining cardiac output based on a thermal attenuation method and a second system for obtaining blood flow velocity based on a thermal-type flowrate measurement. A constituent value is obtained from the cardiac output and blood flow velocity, and the constituent value is held. The apparatus also includes a computing unit for computing cardiac output from the already obtained constituent value and a blood flow velocity obtained at the time of measurement. The constituent value can be updated by re-starting the first system.
