A cuff bag 1 made of a rubber bag or the like is provided on the inner peripheral surface of the cuff band body 2, and the cuff band body is provided corresponding to the portion where the cuff bag 1 is provided. It is formed by attaching a clip plate 3 curved in an arcuate shape in section 2 inside. The clip plate 3 is formed of a rigid synthetic resin molded product having rigidity and elasticity. A reversing ring 14 is provided at one end of the cuff band main body 2, and the other end of the cuff band main body 2 is provided with the reversing ring 1.
The sheet-like fastener 15 is engaged with the sheet-like fastener 15 by turning it over. A pair of engaging protrusions 16 are provided on the outer surface of the clip plate 3, and the engaging protrusions 16 are inserted into the opening 17 of the housing of the sphygmomanometer main body A to engage with the inner peripheral edge thereof. By doing so, the sphygmomanometer main body A and the cuff band B are integrated. And pressurizing pump 9
Is connected to the cuff bag 1 by an air supply pipe 18 so that air can be pumped to the cuff bag 1.

Here, the clip plate 3 is provided with a hinge portion 4 extending in the width direction at one location in the arc direction.
The hinge portion 4 is formed as a thin portion by providing a groove 19 on the outer surface of the clip plate 3 as shown in FIG. As shown in FIGS. 2A and 2B, the clip plate 3 does not expand its arc shape due to the abutting of the inner side surfaces of the concave groove 19, but FIG.
As shown in (c) and (d), the clip plate 3 can be folded inward by bending and rotating inward by the hinge portion 4 so as to widen the space between the inner side surfaces of the concave groove 19. It can be done at any time.

Since the arc shape of the clip plate 3 does not spread in this manner, the ring-shaped shape-retaining action of the cuff band body 2 by the clip plate 3 is not impaired, and the clip plate 3 can be formed in the same manner as in the conventional case. Blood pressure can be measured using the cuff band A. On the other hand, when the sphygmomanometer is stored, the clip plate 3 is bent inward at the hinge portion 4 as shown in FIGS. 2 (c) and 2 (d), so that the cuff band body is shown in phantom in FIG. 2 can be folded inward and the cuff band body 2
Can be folded into a small volume and can be stored in a small volume.

In the embodiment shown in FIG. 2, the hinge portion 4 is provided only at one place of the clip plate 3, but as shown in FIG. 3, the hinge portions 4 are provided at a plurality of places such as two places of the clip plate 3,
The cuff band main body 2 may be made to be able to be made even smaller so that the clip plate 3 can be folded at a plurality of locations. FIG. 4 shows another embodiment of the present invention, in which the clip plate 3 is divided into a main body plate piece 3a and a folding plate piece 3b in the arc direction, and a pair of rotating pieces 20a, 20a are provided. By fixing the respective end portions of the body plate piece 3a and the folding plate piece 3b to the respective rotation pieces 20a, 20a of the hinge 20 that is pivotally attached rotatably, the hinge plate 20 is used to form the body plate piece 3a and the folding plate. The pieces 3b are connected to form the clip plate 3, and in this embodiment, the hinge portion 4 is formed by the hinge 20. This hinge 20 is formed so as to rotate between a state where the rotating pieces 20a, 20a are closed and a state where the rotating pieces 20a are opened up to a maximum of about 180 °.
A and 20a are rotationally biased in the opening direction. Therefore, in this device, the clip plate 3 can be folded as shown in FIG. 4 (b) by rotating the hinge pieces 20a, 20a of the hinge 20 so as to be closed, and the cuff band body 2 can be folded in a small volume. When this is done, the rotating pieces 20a, 20a of the hinge 20 are opened by the force of the spring and the clip plate 3 is opened as shown in FIG.
Returns to the original curved state, and the cuff band body 2 can be automatically opened.

FIG. 5 (a) shows another example of the cuff band B. An insertion ring 23 is attached to the outer surface of one end of the cuff band main body 2, and the cuff band 23 is attached to the insertion ring 23. The other end (the end on the free end side) of the main body 2 is inserted. The planar fastener 15 includes a fastener half body 15a formed of a hook tape provided with a large number of hook pieces, and a fastener half body 15b formed of a loop tape provided with a large number of piles hooked on the hook pieces as a pair. Although formed, the planar fastener 1 is provided inside the insertion ring 23.
One of the fastener halves 15a and 15b (for example, fastener half 15a: fastener half C) of FIG.
It is attached as shown in (b). Insertion ring 2
The other of the fastener halves 15a and 15b of the planar fastener 15 (for example, fastener half 15b: fastener half D) is attached to the inner side surface of the end portion of the cuff band main body 2 passed through 3. Further, near the insertion ring 23, one of the fastener halves 15a and 15b of the planar fastener 15 is attached to the outer surface of the cuff band body 2 (for example, the fastener half 1
5a: fastener half E) is attached. In this case, it can be tightened by passing the arm or wrist through the cuff band body 2 and then attaching the fastener half D to the fastener half E. When the arm or wrist is inserted into or removed from the cuff band body 2, the cuff band body 2 is loosened so that the free end of the cuff band body 2 is inserted through the insertion ring 23.
Once removed from the cuff band body 2 again into the insertion ring 23
It is very troublesome to insert the end of the cuff band main body 2 on the free end side though it is very troublesome to insert the end on the free end side of the cuff band body 2. Therefore, the free end of the cuff band main body 2 can be prevented from coming off the insertion ring 23. Further, since the fastener half C is provided on the insertion ring 23 in this manner, the back surface of the cuff band body 2 is always rubbed against the fastener half C when the cuff band body 2 is tightened or loosened. Therefore, the cuff band body 2 can be prevented from being overtightened, and the cuff band body 2 can be prevented from loosening, so that the cuff band body 2 can be properly tightened at the time of use. The fastener half D provided at the free end of the cuff band body 2 is attached to the front side of the cuff band body 2 as shown by the solid line in FIG. 5 (a), and is shown by the dotted line in FIG. It may be attached to the back side of the cuff band body 2 as described above.

FIG. 6 shows still another example, in which the free end side of the cuff band body 2 is formed long so that it can be folded back when used.
