Abstract

PURPOSE:To provide a cuff band easily wound around a wrist, having stability and capable of well measuring blood pressure even when the thickness of the wrist is different and there is an individual difference in the shape of the wrist by setting the diameter of a flexible almost cylindrical clip plate cut off at a part in the peripheral direction thereof to 40-60mm. CONSTITUTION:Since the min. lateral width of a wrist C is about 50mm, the diameter D of a flexible clip plate 1 is set to 40-60mm. A cuff band (b) is constituted so that the cross-sectional shape thereof is formed into an almost cylindrical shape (almost C-shape) cut off at a part in the peripheral direction thereof and necessarily expanded in use. Since the flexible clip plate 1 having rigidity of a certain degree is laterally expanded, the wrist C is pressed when said clip plate 1 is applied to the wrist C but there are the radius and the ulna in the lateral direction of the wrist C, the flexible clip plate 1 presses said bones. The artery is present in the wrist C in the longitudinal direction thereof and is not excessively pressed by the flexible clip plate 1 and there is no effect in the measurement of a blood pressure value. Since the flexible clip plate 1 is brought to the close contact state with the wrist while pressures the bones, the cuff band (b) can be stably mounted.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a cuff band for a wrist blood pressure monitor, and specifically relates to a technique for adapting the cuff band to the shape of the wrist.

[Prior Art 1] Conventionally, blood pressure has been measured by wrapping a cuff band around the upper arm a, as shown in FIG. 9(a). Further, a flexible clip plate (pressing plate) 1 may be provided in the cuff band. Furthermore, since the thickness of the upper arm a varies from person to person, care must be taken when choosing the shape of the flexible clip plate 1. In other words, since the visibility clip plate 1 is given a certain degree of rigidity, it will not fit depending on the size of the upper arm a. By the way, the upper arm a can be considered to have a roughly cylindrical shape, and the average size is about 70 to 8
Since the diameter is 0 mm, the flexible clip plate 1 may have a cylindrical shape with a diameter of 70 to 80+n+o. FIG. 9(IJ) shows an example of an arm thinner than the flexible clip plate 1, and FIG. 9(e) shows an example of a thicker arm, which is a schematic diagram of only the flexible clip plate 1 and the ischemic cuff 2. . In FIG. 9(b), since the upper arm a is thin, there is a gap between it and the flexible clip plate 1, but the ischemic cuff 2 can expand under pressure to fill the gap. In addition, in FIG. 9(c), since the upper arm a is thick, the flexible clip plate 1 has to be rolled a little wider, but it often comes into contact with the upper arm a.

[Problem to be Solved by the Invention 1] However, a problem arises in the case of the wrist blood pressure monitor shown in FIG. In other words, as shown in Figure 10(a), the wrist C has a semi-fusiform shape, being thinner on the palm side and thicker on the elbow side.
There are also large individual differences. Also, the cross-sectional shape resembles an ellipse.

For example, when using a semicircular flexible clip plate 1 as shown in Fig. 10 (L+) (c), if the wrist is thin as shown in Fig. 10 (b), A gap d is created, and in the case of a thick wrist shown in FIG. 10(C), a gap d is created in the center.

When winding the cuff band, one tries to wind it with force in order to reduce the gap d, but the flexible clip plate 1
has a certain degree of rigidity, so there was a problem that it was uncomfortable.

The present invention was made in view of such problems,
The aim is to create a wrist blood pressure monitor that is easy to wrap around the wrist, is stable, and can accurately measure blood pressure, even if the wrist size or shape varies from person to person. Our goal is to provide cuff belts.

[Means for Solving the Problems] The cuff band of the wrist blood pressure monitor of the present invention is characterized in that the diameter of the flexible clip plate 1 is 40 to 60+ m.

[Effect 1 In this way, the diameter of the flexible clip plate 1 is set to 40 to 60
By setting a+m, the cuff band with a diameter of 40 to 60 mm of the flexible clip plate 1 can actually fit any wrist C.
The flexible clip plate 1 is spread laterally and touches both ends of the wrist C, and the flexible clip plate 1 presses on the bone, thus preventing the flexible clip plate from reaching the artery. It is possible to suppress the pressure caused by 1 and prevent it from affecting the measurement of blood pressure values.

In addition, the flexible clip plate 1 compresses and makes close contact with the radius and ulna of the wrist C that appear on both the left and right sides when the model is held horizontally, making it possible to stably attach the cuff belt. .

[Example J Embodiments of the present invention will be described in detail below based on the drawings.

Figure 1 shows a flexible clip plate 1, which is formed into a substantially cylindrical shape like the one for the upper arm, but the difference from the one for the upper arm is that the diameter is not the average value of the arm, but is Also has a small diameter. In other words, the minimum width of wrist C is approximately 50 m.
m, so the diameter of the visibility clip plate 1 should be 40~
The length shall be 60 mm.

Since the cuff strap has an ischemic cuff 2 and protective decorative cloth on the inside of the flexible clip plate 1, the cuff strap with the diameter of the flexible clip plate 1 from 40 to 6011II11 can actually be used on any wrist. It is small compared to C. The cross-sectional shape of the cuff belt is a roughly cylindrical shape with a portion cut away in the circumferential direction.
It is formed into a C-shape and must be unfolded before use. FIG. 2 shows how the flexible crevice plate 1 is unfolded. Since the cross-sectional shape of the wrist C is similar to an oval, both horizontally long ends first contact the cuff strap, and the flexible clip plate 1 is held at t5.
Spread it in the direction of the arrow in Figure 2. The shape of the flexible clip plate 1 spread out laterally in this way is approximately elliptical, as shown in Fig. PjS2 (a
) shows the situation when the spread is small, and FIG. 2(b) shows the situation when it is large. FIGS. 3(a) and 3(b) show the case where the flexible clip plate 1 is applied to small and large wrists C. Here, another feature of the present invention is that, as shown in FIG. When the flexible clip plate 1 comes into contact with the wrist C, the flexible clip plate 1 presses the wrist C (
It is thought that this may affect the blood pressure value, but there are radius and ulna in the lateral direction of the wrist C (horizontal direction in Fig. 3), and the flexible clip plate 1 presses the bones. I will do it. The artery is located in the wrist CLf) II & direction (vertical direction in FIG. 3), and is less compressed by the flexible clip plate 1, so that it does not affect the measurement of the blood pressure value. Furthermore, since the flexible clip plate 1 presses against the bone, the cuff belt can be stably worn.

The flexible clip plate 1 can be deformed as shown in FIG. 4 to accommodate the fact that the wrist C has a cow spindle shape. Even in the case of FIG. 4, force is applied to the visibility clip plate 1 in the lateral direction as shown in FIG. 2, and the flexible grip plate 1 in FIG. It exhibits a substantially circular cross-sectional shape in any direction.

More specifically, as shown in FIG. 5(a), the flexible clip plate 1 of the present invention has a radius R in the original state where no external force is applied, and as shown in FIG. When expanded, the radius of the curved surface becomes R2,R. by the way,
Since the visibility clip plate 1 is spread out laterally, R2 does not become much larger than R1, and R3 becomes larger. Much R8≦
R2<R2. In determining the degree of spread of the flexible clip plate 1, it is important to pay attention to individual differences in the outer shape of the wrist C where the curved surface is small, that is, the side surface of the wrist C (portion R2). In the present invention, the material of the flexible clip plate 1 is a flexible molded product such as polypropylene, polyethylene, hard vinyl chloride, etc., and the plate thickness is set to 0.5-1 to ensure good spread and compatibility. .5mm.

FIG. 6 shows another embodiment of the flexible clip plate 1, in which seven hooks 3 are provided on the flexible clip plate 1.
The blood pressure monitor main body 4 is fitted into the hook 3 to be attached. The position of the 7-piece 3 is located on the opposite side of the flexible clip plate 1 from the opening 5, so that the blood pressure monitor main body 4 is directly above it when in use with the palm facing up, as shown in the fjrJ7 figure. be. In FIG. 7, 6 is the end of the cuff strap, which has a fastening such as map tape (not shown), and this end 6 is connected to the wrist C1, @ the cuff strap attached. It is fixed to the other end and the cuff belt is fixedly attached to the wrist C. FIG. 8 shows an overall perspective view with a part of the cuff strap cut away, in which a long outer cloth 7 is attached to the outer surface of the flexible clip plate 1 and the -m@ end of the outer cloth 7 is shown. 6 is extended longer than the flexible clip plate 1, and the ischemic cuff 2 is attached to the inner surface of the visible clip plate 1, and is inflated when supplied with pressurized air, and the inner surface of the ischemic cuff 2 is elastic. An inner cloth 8 made of woven fabric is attached to accommodate the expansion and contraction of the ischemic cuff 2 and the expansion of the cuff strap when the cuff strap is attached.

[Effects of the Invention] In summary, the present invention has a flexible clip plate with a diameter of 40 mm.
~60+am, so the cuff band with a diameter of approximately 40~601I111 of the flexible clip plate is actually small compared to any wrist, and the flexible clip plate can be spread laterally to fit around the wrist. It has the advantage of compressing the bones at both ends, thereby suppressing compression of the artery by the flexible clip plate, and preventing it from affecting blood pressure measurement. Furthermore, since the visible clip plate compresses and makes close contact with the radius and ulna of the wrist that appear on both the left and right sides when the palm is held horizontally, there is an advantage that the cuff band can be stably worn.
