  • Patent number: 10687714
    Abstract: To perform measurement of a vascular elasticity rate with high accuracy in a short time. A vascular elasticity rate evaluation apparatus of the present invention includes: a pressure detection unit that detects a pulse wave with an external pressure being applied to a blood vessel; and a control unit that forms a pulse wave amplitude indicating dependent characteristics due to elasticity of the blood vessel from a detection value of the pressure detection unit, calculates a plus area in an elevation process of the pulse wave amplitude and a minus area in a descent process thereof, and calculates the vascular elasticity rate using values thereof.

  • Patent number: 10398371
    Abstract: A problem to be solved is to use a measured pain degree for comparison with a pain degree of another subject or for diagnosis of a disease. A pain measuring device has an electrode to be attached to a subject and a stimulation current generation means generating a stimulation current to be supplied to the electrode. Then, the pain measuring device measures pain felt by the subject based on the stimulation current applied from the electrode to the subject. The pain measuring device has a means to display a relation between a pain measurement value being a logarithmic value or a logarithmic-type value of a value founded on the stimulation current and a value of a VAS or a face scale which the subject selects.
