Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 shows a first embodiment, in which a sphygmomanometer is attached to a main part 1 of a human body such as a wrist or a finger, and a cuff band part 2 for blocking blood.
And a height matching section 3 installed at the height of the heart of the human body
It consists of and. The cuff band portion 2 is provided with a light emitting portion 4. In the figure, X indicates light emission. The light emitting section 4 may be provided in the height adjusting section 3 as shown in FIG. By the way, the main part 1 of the human body such as the wrist or fingertip to which the cuff band 2 is attached is a part whose height with respect to the heart part b is likely to change depending on the upper and lower arms, and the blood pressure changes to the main part 1 due to the head pressure difference. .. The cuff band portion 2 is wound around the main portion 1 and pressure ischemia is performed to measure blood pressure. The height adjusting part 3 is fixed by a chest band or stored in a chest pocket so that it is located on the same horizontal plane as the heart part b.

3 and 4 show a mechanism for keeping the light emitting part 4 horizontal, and a hemispherical weight 8 is housed inside a transparent hollow case 7 so that it can slide sufficiently smoothly. Weight 8
The lower surface of is always oriented in the vertical direction, and the light emitting element 9 as the light emitting section 4 installed on the upper surface of the weight 8 is maintained in the horizontal direction so that the light is emitted in the horizontal direction. Reference numeral 10 is a flexible lead wire, 11 is a terminal, and 12 is a lead wire for external connection. As the light emitting element 9, an LED, a phototransistor, or a laser light emitting element which emits visible light or infrared light is used.
