Description

[Detailed description of the invention] (a) Industrial application field This invention relates to a cuff for a blood pressure monitor, and in particular relates to the structure of the inner bag and outer bag.

(B) Prior Art Generally, a wrist cuff in a blood pressure monitor is wrapped around the upper arm of a person to be measured to supply pressurized air to achieve blood ischemia. As shown in Fig. 6, this armband consists of an inner bag b to which a pipe a is connected, and an inner bag b.
It is composed of an outer bag c in which the
Pressurized air is allowed to flow into the chamber. On the other hand, the outer bag c is composed of a cloth bag, with an outer material d and a lining e.
It is formed by overlapping these and sewing the periphery thereof, and an insertion opening f for the inner bag b is opened on one side.
Therefore, the inner bag b is stored in the outer bag c through the insertion opening f and wrapped around the upper arm, and pressurized air is supplied to the inner bag b.

(c) Problems to be solved by the invention In the above-mentioned arm cuff, the inner bag B has traditionally been the outer bag C.
The inner bag b and the outer bag c were not fixed in any way. With this, when the arm cuff is wrapped around the person to be measured, the inner bag b may shift position within the outer bag c, and when the arm is compressed with pressurized air, the pressure distribution may not always be the same.
This was one of the causes of measurement error.

In addition, since the insertion port f pulls out the pipe a, it always remains open, and furthermore,
It is formed to a certain size in order to be placed in the inner bag b. Therefore, when pressurized air is supplied to the inner bag b to inflate it, there is a problem that the inner bag b protrudes from the insertion opening f. Furthermore, since the inner bag b faces outward from the insertion opening f, there is a problem that it is easily damaged by pins or the like when measuring on a desk.

(d) Means and action for solving the problem This device is composed of a flexible inner bag that expands and contracts when pressurized air flows in and out, and an outer bag that stores this inner bag. An inflow and outflow pipe for pressurized air is connected to the inner bag, and a through hole for this pipe is opened in the outer bag, so that the outer edge of the inner bag is fixed to the outer bag, and the entire outer surface of the inner bag is fixed to the outer bag. It is characterized in that the inner bag is wrapped integrally with the outer bag during measurement, and at the same time, the inner bag is completely surrounded by the outer bag.

(E) Embodiment Hereinafter, one embodiment of this invention will be described in detail based on the drawings.

As shown in FIGS. 1 to 5, reference numeral 1 is a cuff for a blood pressure monitor, which is wrapped around the upper arm of a person to be measured, and pressurized air is supplied thereto.

This cuff 1 is composed of an inner bag 2 and an outer bag 3, and a pipe 4 is connected to the inner bag 2. Inner bag 2
is formed into a flat rectangular bag, which is made by stacking two flexible sheets such as vinyl chloride and gluing all four sides together. And between this sheet, pipe 4
The end of the pipe 4 is inserted, and a pump (not shown) is connected to the other end of the pipe 4, so that pressurized air flows in and out of the inner bag 2, causing the inner bag 2 to expand and contract. . Furthermore, a flange 2a is provided on one of the short sides of the inner bag 2 and extends between both long sides.

On the other hand, the outer bag 3 wraps the inner bag 2 and is formed into a belt shape that is longer than the inner bag 2. This outer bag 3 is formed of a front material 5 and a lining material 6, and the outer material 5 is formed of a cloth portion 5a and a hook-and-loop fastener portion 5b. The cloth portion 5a and the surface fastener portion 5b are formed approximately halfway in the longitudinal direction, and the surface fastener portion 5
The inner bag 2 is stored inside b. The lining 6 is the side that contacts the person to be measured, and is made of a thin, non-stretchable fabric. And lining 6
A pipe 4 is provided on the side of the hook-and-loop fastener portion 5b.
A through hole 6a is formed therein, and a hook-and-loop fastener piece 6b is attached to the back surface of the end on the cloth portion 5a side.

This outer bag 3 has a outer material 5 superimposed on a lining material 6 and is sewn around all four sides to form a sewn portion 7, thereby forming a belt-shaped bag. The inner bag 2 and collar 8 are stored between the lining 6 and the hook-and-loop fastener section 5b, and the flange 2a is located at the joint between the hook-and-loop fastener section 5b and the fabric section 5a.
and the outer bag 3 are sewn to form a sewn portion 9, and the inner bag 2 is entirely covered with the outer bag 3 and is fixed to the outer bag 3.

Note that the collar 8 is formed in an arc shape.

Next, the manufacturing process of this arm cuff 1 will be explained.

First, the inner bag 2 is made by overlapping two sheets, and
The end of the pipe 4 is inserted between the sheets on the side parts, and the entire circumference of the four sides is bonded by welding. At that time, glue one short side slightly on the inside and attach the flange 2.
form a.

On the other hand, as shown in FIG. 3, the outer bag 3 is constructed by stacking a hook-and-loop fastener section 5b and a fabric section 5a on a lining 6 having hook-and-loop fastener pieces 6b and through-holes 6a, so that all four sides of the outer bag 5 and the lining 6 are Sew and form the circumference. In this state, the outer bag 3 can be opened at the joint between the cloth portion 5a and the hook-and-loop fastener portion 5b (see FIG. 2).

Subsequently, the inner bag 2 is inserted into the outer bag 3, and the pipe 4 is pulled out from the through hole 6a. Then, the inner bag 2 is positioned between the hook-and-loop fastener section 5b and the lining 6, and the flange 2a is positioned at the joint between the fabric section 5a and the hook-and-loop fastener section 5b. After storing the collar 8, the flange 2a is sewn together with the outer fabric 5 and the lining 6. As a result, the inner bag 2 is fixed to the outer bag 3, and the cuff 1 is completed (see FIG. 5).

In this embodiment, the inner bag 2 has a flange 2.
Although a is formed only on one side, it may be formed on two to four sides and these two to four sides are sewn to the outer bag 3.

Furthermore, the outer bag 3 may have rounded corners and be sewn on all four sides with bias tape to provide an excellent design.

In addition, the inner bag 2 was inserted between the hook-and-loop fastener section 5b and the fabric section 5a, but when sewing the outer bag 3, the outer edge of the hook-and-loop fastener section 5b (see Fig. 2A) was left open. Insert the inner bag 2 from the outside edge and attach the flange 2a.
It may also be sewn together to close it.

(F) Effects of the device As described above, according to the blood pressure cuff of this device, the inner bag is fixed to the outer bag and the entire outer surface is covered with the outer bag, so that it does not touch the arm of the person being measured. When wrapped, the inner bag does not shift in position within the outer bag, so the pressure distribution acting on the arm etc. is always the same, so accurate measurements can be made.

In addition, since the inner bag is completely enclosed and the insertion port is not left open like in the past, the inner bag does not protrude from the outer bag when pressurized air is supplied, and pins etc. do not come out when measuring on a desk. Since it has a completely double structure, it can prevent damage even if it happens.
