Blood pressure meter cuff

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.

What is claimed is:  
     
         1 . A blood pressure meter cuff comprising: 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.    
     
     
         2 . The blood pressure meter cuff according to  claim 1 , wherein a width, in the axial direction of the limb, of the fluid bag is a width suitable for pressurizing a radial artery present in the downward vicinity of the body surface and adjacent to a radial styloid process of a wrist.  
     
     
         3 . The blood pressure meter cuff according to  claim 1 , wherein a width, in the axial direction of the limb, of the fluid bag is a width suitable for pressurizing a radial artery present in the downward vicinity of the body surface and in an intermediate portion between the radial styloid process of a wrist and the first metacarpal bone base thereof.  
     
     
         4 . The blood pressure meter cuff according to any one of  claims 1  to  3 , wherein a width, in the axial direction of a limb, of the fluid bag is 15 mm or more and 25 mm or less.
