Abstract

Provide is a blood pressure meter cuff capable of avoiding an influence of an edge effect by pressurizing only a portion of a blood vessel in the downward vicinity of the body surface to thereby measure a correct blood pressure. A blood pressure meter cuff 1 includes: a fluid bag into which a fluid is injected; and a fixing tool fixing the fluid bag on a limb of a human body or the like, wherein a width in the axial direction of the limb, of the fluid bag is a value suitable for selectively pressurizing only a portion of a blood vessel present in the downward vicinity of the skin. In a case where pressurization is imposed on only a portion of the radial artery present in the downward vicinity of the body surface and adjacent to a radial styloid process of a wrist, a width, in the axial direction of a limb, of the fluid bag is set to 15 mm or more and 25 mm or less.

Claims

1-4. -4. (canceled)

5. A method for measuring blood pressure, comprising:

fixing a fluid bag for receiving an injected fluid on a limb of a human body or the like at a location on the limb so that, when the fluid is injected into the fluid bag, inflation of the bag selectively pressurizes only a portion of a radial artery present in the downward vicinity of the body surface and in an intermediate portion between a radial styloid process of a wrist and a first metacarpal bone base thereof without pressurizing an ulnar artery of the wrist.

6. The method of claim 5, further comprising sensing a pulse wave at a position between about 5 mm to 15 mm from a top of the radial styloid process.

7. The method of claim 5, further comprising sensing a pulse wave at a position at about the midpoint of a distance between the radial styloid process and the first metacarpal bone base.

8. The method of claim 5, further comprising sensing a pulse wave at a position to a peripheral side of the radial styloid process.
