Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a cuff for a blood pressure monitor for ischemia used in non-invasive blood pressure measurement, and in particular to an improvement in the wrapping mechanism of the cuff. Regarding.

[Prior Art] When non-invasive blood pressure measurement is performed, a compression band called a cuff is usually used to block blood flow in an artery. When wrapping this arm cuff around the arm, it is important to be able to easily obtain a constant bondage state, and also to be able to easily wear it with one hand since the arm on which the arm cuff is wrapped cannot be used.
If the bondage is too strong or too loose, errors will occur in blood pressure measurement, making it impossible to measure blood pressure accurately.

On the other hand, as a conventional arm cuff, a cuff 20 shown in FIG. 2 is cited. Such a cuff has an annular fastener 22 attached to one end thereof, as shown in FIG.
The cuff is worn by passing the other end 21' through the cuff and fixing it with the hooking members 23, 23'.

In addition, according to ``Bracelet for blood pressure cuff'' published in Japanese Patent Publication No. 57-58168, a loop shape is formed in advance on the cuff using an auxiliary band, and after passing the arm through the cuff, it is temporarily fastened. An arm cuff that is worn by tightening an auxiliary band has been proposed.

[Problems to be Solved by the Invention] Let us examine whether the conventional arm cuff as shown in FIG. 2 must satisfy the above-mentioned requirements as an arm cuff.

First of all, since the hanging members 23 and 23' can be hung at any position, it is difficult to obtain a certain tightness, especially when home-use blood pressure monitors are becoming popular these days. , it is difficult for ordinary people without experience and knowledge to obtain a predetermined bondage state.
In addition, in the conventional example shown in Figure 2, the entire cuff turns when tightening when one person is wearing the cuff.
It is difficult to position it, and it is not possible to put it on with one hand.

The present invention was proposed to solve the above-mentioned problems of the prior art, and its purpose is to always obtain a constant bonding condition, which is important when measuring blood pressure. To provide a wrist cuff for blood pressure measurement that can be wrapped in the same tight binding state and that prevents a blood pressure detection part from moving when worn.

[Means for Solving the Problems] A cuff for a blood pressure monitor according to the present invention for achieving the above-mentioned problems has the following configuration. , are provided on the back surface 14 of the arm cuff 1 and the surface 13 of the end portion of the arm cuff 1, and by arbitrarily changing the hanging position of the back surface 14 and the front surface 13 and hanging each other, the inner diameter of the arm cuff can be adjusted. The first hooking means 5, 14 of the surface joint fastener which can be adjusted, and the opposite side which is provided in the middle of the arm cuff 1 and which moves the arm cuff 1 away from the arm in order to assist in easily folding the arm cuff 1. The first part that helps you fold it to the side easily.
a second bending assisting means 10 that assists in easily bending the arm cuff 1 toward the arm side;
1, a first frame 4 that supports the first armband portion between the first bending means 10 and the second bending auxiliary means 11 so that it does not bend at least; The end portion is fixed to the auxiliary means 11, and when the arm cuff 1 is bent toward the opposite side away from the arm using the vicinity 10 of the first bending auxiliary means as a fulcrum, the first
While holding the frame 4 between the front surface 13 of the arm cuff 1 and the back surface of the arm cuff 1,
3 is provided with a second hooking means 7 of a face-to-face fastener for hooking.

[Function] According to the present invention having the above configuration, the first hanging means allows the inner diameter of the wrist cuff to be adjusted by arbitrarily changing the hanging positions of the back side and the front side of the wrist cuff and hanging them on each other. do. The first folding assisting means easily assists in folding the cuff to the side opposite to the arm, and the second folding assisting means assists in easily folding the cuff towards the arm. The second hanging means is configured to connect the first frame body between the front surface of the arm cuff and the back surface of the arm cuff when the arm cuff is bent to the side opposite to the arm near the first bending assisting means. While being held between them, it is hooked to the surface of the arm cuff, which is one of the first hooking means.

In this way, after the arm cuff is bent near the first bending auxiliary means and the second hanging means is hooked onto the surface of the arm cuff, a predetermined binding state can be obtained according to the thickness of the arm. If the arm cuff is made into a ring shape by hooking the first hooking means to the arm cuff, a constant binding state can be obtained at all times when the arm cuff is used unless the first hooking means is released. can.

[Embodiments] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

<Configuration of arm cuff> FIG. 1 is a sectional view of a blood pressure measuring arm cuff according to an embodiment of the present invention in an unfolded state. arm cuff 1
is created as follows. For example, two sheets of foldable pile fabric, raised in a loop shape, coated with a thermoplastic synthetic resin sheet such as vinyl chloride on the back side, with the raised side facing up (the synthetic resin sheet sides overlap). Superimpose it like this,
The surrounding area is joined using high frequency welding. During this high-frequency welding, there is an air bag 2 for pressurization that expands to block blood flow in the artery, and a cuff 1.
an elastic frame 3 made of a material such as polypropylene, and a flexible frame 4 for maintaining the external shape of the air bag 2 and directing the inflation pressure of the air bag 2 toward the arm side.
is placed inside. By high-frequency welding the circumference of the cuff, the cuff can be made into an airtight bag, so the air bag 2 can be omitted.

In addition, in Fig. 1, the raised loop-shaped pile fabric is not clearly shown, but it is actually the third pile fabric.
As shown in the lower part of the figure, the hanging members (5, 6,
7) has a large number of hook-shaped protrusions flocked to it so that it can be hooked onto the pile fabric. This pile fabric is brushed on the entire arm cuff (excluding the hanging part), so the hanging part can be any part of the cuff.
In other words, it can be adjusted to fit the size of your arm. Further, although the elastic frame 3 is shown in a planar shape in FIG. 1, it actually has a shape that surrounds the arm. Similarly, the flexible frame 4 also has a shape with curvature. 8 is a microphone pocket for storing a microphone for detecting corotroph sounds. The above is the original configuration of the arm cuff 1.

In order to achieve the above-mentioned problems of the present invention, the arm cuff 1 according to the embodiment has been further processed as follows, as shown in FIG. First, as described above, the hanging members 5 and 6 having hook-shaped projections are attached to the cuff 1 at the positions shown in the figure. These positions may be such that the inner diameter of the wristband can be adjusted to match the thickness of the arm. That is, the hanging member 7 is hung at an appropriate position on the arm cuff surface 13, and the hanging member 5 is hung at an arbitrary position on the arm cuff back surface 14 depending on the thickness of the arm. The hanging member 6 is for fixing the arm cuff so that the end 16 side of the arm cuff does not become loose when the arm cuff is worn on a thin arm.

Reference numerals 10 and 11 indicate folding portions which are bent at the front so that the cuff can be easily bent at these portions. The bending portions 10 and 11 are provided to allow the wristband 1 to be easily bent when worn, and the method of bending is not limited as long as it suits the purpose. 7 is a hanging member that, unlike 5 and 6, only one end thereof is high-frequency welded to the cuff 1. A gripping part 12 is provided at the other end of the hanging member 7, and the operator grips this gripping part 12 to wear the cuff 1 on his arm. 4 is the arm cuff 1 for the purpose of making it easier to attach the arm cuff to the arm for reasons to be described later.
A flexible frame is inserted into the frame.

Figure 4 shows the arm cuff of the above embodiment in an unfolded state.
It is a top view seen from the front side (outside) of an arm cuff. 9 is an air port for supplying air to the air bag 2.

<Example of Wearing Procedure>...Figs. 5a and 5b Using Figs. 5a and 5b, the concept of the embodiment according to the present invention will be explained while explaining the method of wearing the arm cuff. The arm cuff according to the present invention has been devised so that it can be adapted to people with various arm thicknesses, and here in Fig. 5, an example will be explained in the case where the wearer's arm is thick. The case where the arm is thin will be discussed later (Figure 7).

In FIG. 5a, the arm cuff 1 first bends the arm cuff 1 at the bending parts 10 and 11 using the gripping part 12 before hooking the hanging member 5 onto the surface of the cuff 1. Then, the hanging member 7 is hung on the surface of the cuff 1. As mentioned above, the bending parts 10 and 11 are easy to bend as shown in FIG. 5a. This hanging member 7
The operation of attaching the cuff 1 may be performed before or after the cuff 1 is attached to the arm.

Next, after putting on the arm cuff 1 and positioning it so that the microphone in the microphone pocket 8 is at a predetermined position, the arm cuff 1 is attached while adjusting the hanging member 5 to obtain a predetermined degree of tightness. Hang it on the surface of 1. The binding strength at this time is set to be a binding strength suitable for starting blood pressure measurement. In this way, the wearing of the arm cuff is completed. Incidentally, since the hanging position of the hanging member 5 can be set freely, the diameter of the arm cuff can be freely adjusted within a range of about 6 to 12 cm according to the thickness of the operator's arm.

Next, when the blood pressure measurement is completed after the fitting is properly fitted to the arm, as shown in Fig. 5b.
As shown in Figure 3, remove only the hanging member 7 and remove the cuff from your arm. After that, if you want to put the cuff on your arm again, that is, if you want to hang the hanging member 7,
The flexible frame 4 is forcibly bent to the position 10, 11.
Therefore, unless the hooking member 5 is removed, if the hooking member 7 is hooked, the same binding condition as before can be obtained. In other words, as long as the same operator uses the arm cuff, once the hanging position of the hanging member 5 is determined, the arm cuff can be worn by simply attaching and detaching the hanging member 7, and the same degree of tightness can be achieved. will be obtained. It is very important that a constant state of restraint is always obtained during this blood pressure measurement.

The flexible frame 4 and the bending parts 10 and 1 play an important role in attaching and detaching the hanging member 7.
It is 1. Since the bending parts 10 and 11 are bent in a predetermined direction, the hanging member 7 can be easily bent when worn, and this ease of hanging means that when the arm cuff 1 is finally tied up. In addition, it prevents the microphone, which has been carefully set on the artery, from moving due to movement of the cuff. Furthermore, when hanging the hanging member 5, it is desirable to ensure that the arm cuff is folded at the positions 10 and 11, so the width of the flexible frame 4 is set at the bending portions 10, 11. Preferably, the width is between 11 and 11. The grip portion 12 for facilitating the hanging of the hanging member 7 may be formed by welding reinforcing cloth to the back of the hanging member 7 or by folding back the end portion of the hanging member 7. In addition, since the hanging member 7 is repeatedly attached and detached, another hanging member with raised loops may be welded to the position where the hanging member 7 is hooked, separately from the arm cuff surface for reinforcement. . In addition, since the bending parts 10 and 11 only need to put the cuff in a biased state, even if the bending parts 10 and 11 are bent to create a biased state as in the above embodiment, they can be made by bending a flexible member. may be inserted inside the cuff.

FIG. 6 shows a perspective view of the arm cuff wrapped around it.

<Modification>...Fig. 7 In the embodiment shown in Fig. 5, since the arm is thick, the end 16 side of the cuff is fixed without being dangling. FIG. 7 shows an example of how the arm cuff is worn by a wearer with thin arms, with the overall length of the cuff being made longer in order to emphasize the function of the hanging member 6. If the arm cuff is long as a whole and the arm is thin, a considerable length of the arm cuff on the end 16 side will not be hooked, leaving it in a "dangling" state.
Therefore, as shown in FIG. 7, the cuff is folded back and the hanging member 6 is hung on the surface of the cuff.

The reason why the lengths of the hanging members 5 and 6 in the embodiment of FIG. 1 in the longitudinal direction are shorter than that in FIG. 7 is because
This is because FIG. 1 corresponds to the basic concept of the embodiment. However, if the hanging member 5 is short, the problem described in FIG. 7 will occur even if the arm is not particularly thin. In order to solve this problem, one method is to make the length of the hanging member 5 sufficiently long as shown in FIG. In this way, the hanging member 5 can be attached with a considerable degree of freedom.
is hooked to the back surface 14, and the above-mentioned "dangling" state is eliminated. As a second method, the member 5 shown in FIG. In the rolled state, it is attached to the surface 13 side of the cuff.

<Effects of the Embodiment> Thus, if the above-mentioned arm cuff is used, if the arm thickness is the same, once the hanging position of the hanging member 5 is determined, the hanging position of the hanging member 7 can be simply hung. An arm cuff can be attached to the arm with the same binding level. The hanging member 7 is extremely easy to hang due to the functions of the bending parts 10, 11 and the frame 4, so even if one person has to fix the cuff on the arm, it can be done easily and reliably. It can be fixed to Nowadays, many personal blood pressure monitors are in widespread use, and the arm cuff of this embodiment is highly effective in view of its ease of operation and simplicity. Also, by changing the length of the hanging member,
Alternatively, by providing the hooking member 6, this arm cuff can be applied to people with various arm thicknesses.

In the above embodiment, the hook-shaped protrusion and the raised raised portions on the loops are used to realize the hook-shaped protrusion so that the diameter of the armband can be freely adjusted. However, if the diameter of the armband can be freely adjusted, Alternatively, it may be provided with many buttons or hooks.

[Effects of the invention] As explained above, according to the invention, in order to always obtain a constant binding state, which is important when measuring blood pressure, once the hanging position is determined, the wrapping state of the binding state is always the same. It is possible to provide a wrist cuff for blood pressure measurement in which the blood pressure detection part does not move when worn.

Furthermore, according to a preferred embodiment of the present invention, the arm cuff is provided with a bending portion at a predetermined position, and the arm cuff is reliably bent at the bending portion.
Since the frame supports the arm cuff so that it does not bend between the bent portions, the arm cuff can be worn reliably even with one hand.
