Description

[Detailed Description of the Invention] The present invention relates to a wrist cuff for a blood pressure monitor, and particularly to a tightening device that improves the adhesion of the part to be measured.

Conventionally, a cuff for a blood pressure monitor that automatically measures blood pressure has, as shown in FIG.
A microphone 3 and a sound collection cuff (not shown) are housed, and a rectangular metal frame 4 is provided at one end of the cuff 1.
is provided, the other end of the arm cuff 1 is inserted into the metal frame 4,
It is known that it can be folded back and fastened to the arm.

By the way, the upper arm of the human body, which is the part where blood pressure is measured, is not originally cylindrical, but rather conical.
When the rectangular cuff 1 is aligned and wrapped around the upper arm, a gap 6 is created in the direction of the human's upper arm 5 as shown in FIG.
is separated from the arm, making detection of Korotkoff sounds unstable. Alternatively, if the cuff 1 is wrapped diagonally around the upper arm in order to eliminate the gap 6, the cuff 1 will not be tightened reliably, and the degree of adhesion to the arm will vary depending on the way the cuff is wrapped, resulting in variations in measurement values. It gives rise to

In order to eliminate such drawbacks, as shown in FIG.
It has also been proposed that the curved ischemic cuff 7 is housed in a truncated cone shape when wrapped around the upper arm, but such a structure would require the manufacturing of the arm cuff and the manufacturing of the curved ischemic cuff. Another disadvantage was that it was difficult to assemble.

In view of the above-mentioned drawbacks, the present invention uses an arm cuff whose unfolded shape is a rectangle, and attaches the arm cuff to one end with a hooking means for hanging the other band of the arm cuff and folding it back. By providing the hanging means at an angle with respect to the width direction of the arm cuff, the arm cuff can be wrapped around the part to be measured in a substantially truncated conical shape, thereby improving the tightness of the arm cuff to the part to be measured. It is an object of the present invention to provide an improved tightening device for a cuff for a blood pressure monitor.

Hereinafter, first and second embodiments using the present invention will be described in detail with reference to the drawings.

In FIG. 4, reference numeral 10 denotes a cuff made of cloth sewn into a bag shape. Inside the cuff sewn into a bag shape, there is an ischemic cuff 11 made of an elastic material such as rubber, and a microphone 1.
A rectangular frame 13 made of a metal rod or synthetic resin serves as a hooking means for hanging the other end 10b on one end 10a of the arm cuff 10. It is sewn diagonally to the width direction of the cuff. In this embodiment, the arm cuff 10 is wrapped around the upper arm, which is the part to be measured.
0 through the other end 10b, fold back from the frame 13, and tighten. Therefore, if the frame 13 attached to one end 10a of the arm cuff 10 and the edge of the arm cuff 10 form an obtuse angle, the frame 13 can be wrapped around the upper arm with the obtuse edge facing toward the hand. Since it is attached diagonally, the obtuse angle edge is tightened thinly, creating a roughly truncated cone shape that roughly follows the shape of the upper arm.
Wraps well with good adhesion.

FIG. 5 shows another embodiment using the present invention, in which a rectangular plate 15 is sewn to one end 14a of a cuff 14 formed similarly to the embodiment shown in FIG. A long hole 15a, which constitutes a hooking means for inserting the other end 14b of the armband 14 and folding it back, is formed in the plate 15 at an angle to the width direction of the armband 14. ing. In this embodiment as well, similarly to the embodiment shown in FIG. 4, the arm cuff 14 is wrapped around the upper arm, the other end 14b of the arm cuff 14 is inserted into the elongated hole 15a of the plate 15, and the arm cuff 14 is folded back and tightened. ,
It has a truncated cone shape that matches the shape of the upper arm, which is the part to be measured, and can be wrapped around the arm with good adhesion.

According to the results of actual measurements on the upper arm, which is the part to be measured, the angle of inclination of the above-mentioned hooking means at one end of the arm cuff with respect to the width direction of the arm cuff is 7.5 to 10.5 degrees for men, and 7.5 to 10.5 degrees for women. It has been actually measured that the angle is within the range of 7.2 to 8.2 degrees, and good results have been obtained when the elongated hole 15a of the frame 13 or plate 15 is set within the above-mentioned angle range.

Note that the present invention is not limited to the above-mentioned embodiments,
The present invention can also be used in a case where the frame 13 described above is formed into a triangular or trapezoidal shape, or where the elongated hole 15a provided in the plate 15 is formed into a triangular or trapezoidal shape.

As described above, the present invention has a hooking means provided at one end for hanging and folding the other end of the arm cuff, which is formed obliquely with respect to the width direction of the arm cuff. It is wrapped in a conical shape. Therefore, it is possible to wrap the microphone tightly around the upper arm, which is the part to be measured, and there is an advantage that the closeness of the microphone housed in the cuff to the part to be measured is improved, and the detection of Korotkoff sounds is ensured.
