BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wrist sphygmomanometer cuff used for measuring blood pressure by, for example, blocking the artery of a wrist.

FIGS. 5 and 6 are perspective views showing a conventional wrist sphygmomanometer cuff. Wrist cuff for a blood pressure monitor shown in FIG. 5,
One end 51 of the band-shaped cuff main body 5 containing the air bag is fixed to the ring body 52 and the other end 53 of the cuff main body is connected to the ring body 5.
2 is inserted. At the time of blood pressure measurement, the cuff main body is positioned at the wrist A through the hand B on the annular portion of the cuff main body (the portion protruding cylindrically from the ring body 52), and then the insertion end of the cuff main body protruding outward from the ring body 52 Pull 53 and wrap cuff around wrist.

The cuff for a wrist sphygmomanometer shown in FIG. 6 has an air bag provided between an outer sheet 61 and an inner sheet 62, and a substantially tubular spring plate curler 63 is provided between the air sheet and the outer sheet 61. And the overall shape of the cuff body is set to be almost cylindrical. When measuring the blood pressure, the slit portion (slight gap-like opening) 64 of the cylindrical cuff body is pushed open,
The opening is enlarged, and the cuff body is attached to the wrist through the wrist A to be held.

[0004]

In the above-described conventional ring-type cuff (cuff shown in FIG. 5 ), when worn on the wrist, the ring-shaped cuff body is temporarily expanded to a size that allows the palm to pass through. After inserting the palm and corresponding to the wrist position, it is necessary to tighten the cuff body to the size of the wrist. Therefore, it is not necessary to set the length of the cuff body excessively long, and the position of the wrist artery site and the air bag of the cuff are shifted depending on the tightening state due to the large and small diameter of the measured portion (wrist). There are drawbacks such as the inability to perform accurate blood pressure measurement. On the other hand, in the conventional curl type cuff (cuff shown in FIG. 6 ), since the cuff itself is substantially cylindrical due to the curl, when it is attached to the wrist, the spring-made cylindrical curl must be at least the width of the wrist. And the slit diameter needs to be increased, which is disadvantageous in that the cuff mounting operation is troublesome.

[0005] This invention solves the above problems, there is no displacement between the artery site of the wrist and the air bag of the cuff when tightening the cuff, and it is easy to use regardless of the size of the wrist and is easy to use. An object of the present invention is to provide a cuff for a wrist sphygmomanometer.

[0006]

The cuff for a wrist sphygmomanometer according to the present invention includes a quarter-peripheral portion whose cross-sectional shape is cut by a major axis and a minor axis of an ellipse, and about two-half of the ellipse. The curler having a circumference of 1 is integrally mounted on the belt.

[0007] In the wrist sphygmomanometer cuff having such a configuration, the shape of the curler is set so as to have, for example, a "" -shaped cross section. The air bag is provided inside the curler having the special shape, and this portion corresponds to the wrist of the cuff. Therefore, the curler portion corresponding to the wrist has a large opening, and the cuff can be made to correspond to the wrist simply by applying from above the wrist, and in this state, only one end of the cuff (the side opposite to the curler) is wound. Can be installed with. Thus, when the cuff is tightened, it is possible to perform appropriate tightening for blood pressure measurement without shifting the position of the artery of the wrist and the air bladder. Also, since the opening of the wrist-corresponding part of the cuff itself is large depending on the curler, it can not be used regardless of the size of the wrist circumference
When mounting on the wrist, there is no need to expand the opening, and mounting is easy.

[0008]

FIG. 1 is a sectional view of a main part showing a specific embodiment of a wrist sphygmomanometer cuff according to the present invention. FIG. 2 is an enlarged view of an air bag portion of the cuff.

In the wrist sphygmomanometer cuff, an air bladder 3 is internally provided between an outer sheet 1 and an inner sheet 2 forming a band 10, and a special air bag 3 is provided between the air bladder 3 and the outer sheet 1. A curler 4 having a shape is arranged and configured. Corresponding fasteners 1a, 2a are respectively attached to the appropriate positions on the outer surface of the outer sheet 1 and the appropriate positions on the inner surface of the inner sheet 2. The feature of this invention lies in the shape of the curler 4. That is, as shown in FIG. 3, the curler 4 includes a quarter-peripheral portion whose cross-sectional shape is cut by the major axis and the minor axis of the ellipse, and has a length of about a half of the ellipse. It has been set. The curler 4 is formed of, for example, a synthetic resin material and has a hardness that can withstand a cuff winding force. The curler 4 is a flat plate having a fixed width and length.
It is bent and shaped in the shape of a letter. The curler 4 having this special shape is internally fixed and disposed between the air bladder 3 and the outer sheet 1 so as to be interposed therebetween. 4 parts of this curler (air bag 3
(A part of the curler 4) corresponding to the wrist which is the measurement site, and the opening 11 of the corresponding part is large.

In the wrist sphygmomanometer cuff having such a configuration, the curler 4 corresponding to the wrist A as the measurement site is used.
The opening portion 11 is large. Therefore, as shown in FIG. 4, the cuff can be made to correspond to the wrist A only by applying from above the wrist A, and in this state, one end (the opposite side to the curler 4) 12 of the cuff is wound, and the fastener 1a, It can be mounted and held only by bonding (engaging) the 2a. Thus, when the cuff is tightened, it is possible to perform appropriate tightening for blood pressure measurement without shifting the position of the artery of the wrist A and the air bladder 3. In addition, since the opening 11 of the cuff itself corresponding to the wrist is large due to the curler 4, the opening 11 can be used regardless of the size of the circumference of the wrist A. Easy to install.

[0011]

According to the present invention, as described above, the cross-sectional shape includes the quarter-circumferential portion cut by the major axis and the minor axis of the ellipse, and has a half-circumferential length of the ellipse. Since the curler is provided integrally with the band, the curler portion corresponding to the wrist as the measurement site has a large opening. Therefore, the cuff can be made to correspond to the wrist only by applying from above the wrist, and in this state, the cuff can be mounted simply by winding one end of the cuff. Thereby, at the time of cuff tightening, appropriate tightening for blood pressure measurement can be performed without displacing the position of the artery of the wrist and the air bladder. In addition, the curler has a large opening at the corresponding part of the wrist of the cuff, so it can be used regardless of the size of the wrist circumference. It has an excellent effect of achieving the purpose of the invention.
