FIG. 1 shows a sphygmomanometer ischemic cuff 1 that has been conventionally used on the upper arm, and has a structure in which the center portion expands due to internal pressure. In the above-mentioned ischemic cuff, as shown in FIG.
When the superficial artery 2 is narrowed, even if there is soft tissue 4 around the superficial artery 2, the force generated by the internal pressure of the cuff 1 is dispersed into the force F 1 directed toward the living body and the tension force F 2 of the cuff. The drawback was that blood ischemia was not sufficiently achieved.

The present invention will be explained below based on the drawings shown as examples.

It is made of flexible rubber or the like, and 6 is an outer shell for forming a tube-shaped cuff 7, which extends toward the living body side. And by plate 8,
The cuff 7 is narrowed between it and the living body surface. A hole 9 for pressurization and exhaust is provided in the center of the cuff 7 and plate 8.

の長手方向に長い形状にしておく。 FIG. 3 shows the case of ischemizing the radial artery 10 using the above-mentioned ischemic cuff. In the wrist, radius 1
1. There are hard tissues such as ulna 12 and muscles 13.
There are few soft tissues 14. In the wrist, the radial artery 10 is wrapped at the lower side by the radius 11 and is at a position where it is pressed from the side by the muscles 13. Here, the diameter r of the cuff 7 is made larger than the diameter of a superficial artery such as the radial artery 10 and smaller than the distance between the radius 11 and the muscle 13, so that the cuff 7
Avoid contact with hard living tissue such as 3rd grade. Further, the ischemic cuff 7 is shaped to be long in the longitudinal direction along the radial artery 10.

できることは言うまでもない。 In the ischemic cuff 7 having the above configuration, the soft tissue 14
Although it compresses and deforms, little tension is generated and sufficient blood ischemia can be achieved. Further, as shown in FIG. 4, pressure perpendicular to the longitudinal direction of the radial artery 10 is applied to the radial artery 10, so the cuff pressure during ischemia and the systolic blood pressure match. Furthermore, since the ischemic cuff 7 is long in the longitudinal direction of the artery, it is possible to perform ischemia over a wide area, and the efficiency with which the ischemic cuff 7 compresses the radial artery 10 is improved. It goes without saying that the blood ischemic cuff of the present invention can be applied not only to the wrist but also to areas where there is a superficial artery that flows through a portion pinched by hard internal tissues in a living body.

Here is an example incorporated into. 17 is a band for fixing the blood pressure monitor. In this case, since the plate 8 and the intake/exhaust port 9 are installed above the ischemic cuff 7, that is, on the side of the blood pressure monitor body 16, there is an effect of promoting pressurization.
