  • Blood flow meter and measurement device
    Patent number: 11330990
    Abstract: A blood flow meter capable of measuring the flow rate of the blood flow with high accuracy in a blood vessel of a living body is provided. An element holding body having a tubular shape and having an outer diameter smaller than or equal to the outer diameter of a hollow shaft, which has flexibility and is insertable into a blood vessel, is provided on the distal side of the shaft so as to be coaxial with the shaft. A flow rate sensor is accommodated in the element holding body. The flow rate sensor has a measurement element in which a nickel wire is spirally wound to be formed into a coil shape so that adjacent nickel wires are not in contact with each other and are insulated. A thermal conductive insulating member is provided between the flow rate sensor and the element holding body in the element holding body and the flow rate sensor is fixed in the element holding body by the insulating member.
