Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a cuff, particularly a cuff for a blood pressure monitor.

[Prior art]

There are two types of wristbands for blood pressure monitors: a hard type and a soft type.

As shown in FIG. 7, a soft type armband has a D-ring 3 at one end of the armband main body 2, which is formed into a band shape with an air bag 2c housed between a front cloth 2a and a back cloth 2b. A joining member 4 is provided at the other end.
a is attached, and the other end is attached to D ring 3.
The cuff main body 2 is wound around the arm by folding it back and pasting and bonding the joining member 4a to the surface cloth 2a, and the cuff main body 2 is flexible and has a flat shape. This is why it is called this way. In addition, as shown in FIG. 8, the soft type arm cuff has an annular shape so that one longitudinal end of the arm cuff body 2 is connected to the vicinity of the other end so that the arm can be inserted through the arm cuff body 2. Some have a gripping piece 4 formed on the outside (the side opposite to the side that contacts the arm).

On the other hand, as shown in FIG. 9, a hard type arm cuff has an arc-shaped flexible plate 6 housed inside the arm cuff main body 2, and the arm cuff main body 2 is held in an annular shape in advance. It is called this because it is easy to pass the arm through and has an image of being hard.
In FIG. 9, the same members as the arm cuff components shown in FIGS. 7 and 8 are designated by the same reference numerals, and redundant explanation thereof will be omitted.

[Problem that the invention attempts to solve]

However, when trying to wear the arm cuff shown in FIG. 8 or 9 with one hand, the arm cuff main body 2
When the arm cuff body 2 is wrapped around the arm, the arm cuff body 2 slips around the arm and spins idly. For this reason, it is not possible to easily put it on with one hand, and it is troublesome to have to press the arm cuff main body 2 against the arm with the other hand to prevent it from rotating idly. This is especially a problem when used on elderly people or children with thin arms.

The present invention was devised in view of the problems of the prior art, and its purpose is to provide a blood pressure monitor cuff that is very easy to wear.

[Means for Solving the Problems] In order to achieve the above object, the blood pressure cuff according to the present invention includes a cuff body formed in an annular shape through which the arm can be inserted, and an outer side of the cuff body. A cuff for a blood pressure monitor, comprising: a gripping piece that protrudes from the cuff and wraps the cuff main body around the arm; and a connecting member interposed between the gripping piece and the cuff main body. An arc-shaped tongue is rotatably provided on the inside of the tongue, and the convex side of the tongue that contacts the arm cuff body is made easy to slide, whereas the concave side of the tongue that comes into contact with the arm is made difficult to slip. This is what I did.

[Effect]

Since the concave side of the tongue body that contacts the arm is hard to slip, that is, the friction coefficient is large, the frictional force generated between the tongue body and the arm prevents free rotation of the cuff main body in the circumferential direction. On the other hand, since the convex side of the tongue body that contacts the cuff body is easy to slip, that is, the coefficient of friction is small, the cuff body can slide on the convex side of the tongue body. Therefore, it is possible to smoothly tighten the cuff main body around the arm, that is, to form a winding device.

〔Example〕

Next, embodiments of the present invention will be described based on the drawings.

Figures 1 to 4 show one embodiment of the present invention, in which Figure 1 is a perspective view of a blood pressure monitor cuff (soft type), Figure 2 is a longitudinal sectional view of the wrist cuff, and Figure 3 is a longitudinal cross-sectional view of the wrist cuff. Diagrams a, b
Figure 4a and b are perspective views showing how the arm cuff is used.
FIG. 2 is a side view showing the arm cuff in use.

In these figures, reference numeral 10 indicates an integrated arm cuff body with an air bag portion 16 provided between a front cloth 12 and a back cloth 14. The cuff main body 10 is formed into an annular shape with one end of the band connected to the back side near the other end, and the other end protrudes outward from the annular part so that it can be grasped by hand. It is a tongue-shaped gripping piece 17 that can be held in place. A joining member 18 is attached to this gripping piece 17, and by pressing this joining member 18 against the fluffy surface cloth 12 of the arm cuff main body 10, the gripping piece 17 can be moved to any position outside the arm cuff main body 10. It is now possible to join to. As shown in Utility Model Publication No. 59-37205, the cuff main body 10 has a structure in which a front cloth 12 and a back cloth 14 made of thermocompression resin are crimped together to integrally form an air bag portion between the two. Alternatively, a rubber air bag may be housed between the front cloth 12 and the back cloth 14 and sewn together. Reference numeral 13 in FIGS. 1 and 2 indicates a thermocompression bonded joint.

An arc-shaped tongue body 30 is attached to the inner side of the arm cuff body 10 near the base of the gripping piece 17 via a cloth material 20. The tongue body 30 has a cloth material 34 with a large friction coefficient affixed to the concave side of a plastic curved plate 32, and a cloth material 36 with a small friction coefficient (a cloth material integrated with the cloth material 20) on the convex side of the curved plate 32. ) is attached and integrated, and is made by sandwiching the curved plate 32 between a cloth material 34 and a cloth material 36 from both sides, and bonding the peripheral edges of the cloth materials 34 and 36 by, for example, thermocompression.

Further, the width d of the tongue body 30 is slightly smaller than the width d ₁ of the arm cuff main body 10, so that when worn on the arm, the tongue body 30 is hidden behind the arm cuff main body 10 and does not look bad. In addition, the tongue body 3 including the cloth member 20
0 The entire circumferential length is approximately 1/3 of the inner circumference of the cuff body.
The length in the circumferential direction of the curved plate 32 is approximately 1/4 to 1/3 of the inner circumferential length of the arm cuff main body 10. This has the advantage that the arm cuff can be folded into a small size without being bulky, and the case in which the arm cuff is stored can also be made smaller.

Next, with reference to FIGS. 3 and 4, the procedure for attaching the cuff to the arm will be described.

First, as shown in FIGS. 3a and 4a, after inserting the arm 40 into the cuff main body 10 and aligning the position of the blood pressure sensor (not shown) in the cuff main body 10 with the brachial artery, Pull the gripping piece 17 upward (in the direction of arrow A). Along with this, the tongue body 30 hangs down along the surface of the arm 40 due to its own weight, and the cloth material 20 is urged inward by the back cloth 14, so that the cloth material 34 is pressed against the arm 40. Become. Next, as shown by the arrow B in FIG. 3b and FIG. cloth material 3
4 is in close contact with the arm 40. And cloth material 3
The contact friction force between 4 and the arm is large, and the tongue body 30
It is restrained by the arm 40 by the anti-slip effect in the direction of arrow C in Figure b, thereby suppressing the arm cuff from spinning idly. On the other hand, by pulling the gripping piece 17 clockwise, the back cloth 14 of the wristband main body 10 is
It attempts to move along the cloth material 36, as shown by arrow D in FIG. At this time, since the friction coefficient of the cloth material 36 is small, the back cloth 14 slides, and the cuff main body 10 is smoothly wrapped around the arm 40. That is, the tongue body 30 acts as a fulcrum for wrapping the arm cuff main body 10, and the arm cuff main body 10 is squeezed as the gripping piece 17 is pulled and becomes properly wrapped around the arm 40. After that, the joining member 18 is attached to the surface cloth 1 of the arm cuff body.
2 to complete wearing the arm cuff. and,
By operating a predetermined switch, the air bag portion 16 inside the cuff main body 10 is released via an air supply/discharge pipe (not shown).
Compressed air is supplied to inflate the cuff main body 10 to put the arm 40 in a compressed state, making it possible to measure blood pressure.

In this way, in this embodiment, the tongue body 30 provided inside the arm cuff main body 10 comes into close contact with the arm 40 and prevents the arm cuff main body 10 from spinning idle, so that the cuff main body 10 can be tightened and wrapped smoothly. Anyone can easily insert the cuff onto the arm 40 with one hand.
