Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a band for measuring blood pressure used for measuring blood pressure and a sphygmomanometer using the same. The present invention relates to a band for measuring blood pressure which is excellent in a feeling of being attached to the skin when used, and a sphygmomanometer using the same.

[0002]

2. Description of the Related Art Conventionally, in a sphygmomanometer for measuring blood pressure by narrowing an arm band (band) on an arm, a pressure bag for measuring blood pressure is mounted in the arm band. By introducing air into this pressurized bag, the pressurized bag expands,
For example, the arm, which is the measurement site, is strangled so that the blood pressure can be substantially measured.

[0003] As a material for the pressurized bag, a material used in a doctor's office, a hospital, or the like is generally made of a latex material because measurement accuracy and durability are strongly required. Since those which are used simply are strongly demanded for cost reduction and compactness, those made of vinyl chloride are generally used.

[0004] Such a pressurized bag is formed in advance in a bag-like form separately from the band-shaped main body. That is, in the case of a latex material, a pressurized bag body of a bag-like material is manufactured in advance by a dipping method, and in the case of a vinyl chloride material, a sheet-like material after two sheets are stacked. A pressurized bag body of a bag-like material is manufactured in advance by the fusion method. Then, the pressurized bag manufactured in this manner is incorporated into a band-shaped band main body and integrated to complete a blood pressure measurement band.

[0005] However, in the conventional manufacturing method in which the pressurized bag is separately formed and incorporated into the belt main body, the members are individually present, and the manufacturing process for combining them is complicated, so that the productivity is reduced. There is a problem that it is difficult to reduce the cost because the cost does not rise.

Under such circumstances, the present applicant has already proposed in Japanese Patent Application No. 2001-26272 that a pressure bag is integrally formed by using a sheet member constituting a belt body. ing. As an example of a mass product in such a proposed specification, for example, a resin layer having a thickness (for example, 50 μm) that can function as an airtight bag is coated (laminated) on a base material such as a nonwoven fabric or a cotton fabric. It is conceivable to prepare two sheets of the resin layer and stack them so that these resin layers face each other, and then form a bag by fusing (welding) a predetermined portion.

However, in such a specification, the entire base material must be coated in advance with a resin layer having such a thickness that an airtight bag can be formed on the base material. for that reason,
Due to the effect of the relatively thick coated resin layer, the original excellent texture (feel) of the base material such as nonwoven fabric and cotton fabric
May not be able to take full advantage of it.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to FIGS. 1 (a) and 1 (b).

FIG. 1A is a schematic plan view showing an example of a blood pressure measurement band 1 integrally formed with a pressure bag 20. FIG. 1B is a plan view of FIG. 2 is a cross-sectional view taken along the line AA of FIG. 1, and is drawn in a state where the pressure bag is inflated in order to make the location of the pressure bag 20 easy to understand. Note that the area (grain-like portion) to which a plurality of dots are attached in FIG. 1A indicates a fused portion of the film.

The band 1 for measuring blood pressure of the present invention shown in FIG.
Exemplifies a type used by being wound around an arm for measuring blood pressure. Apart from this form, there is also a type in which the band is set in a ring shape in advance, and an arm is inserted into the ring shape and used, for example. This is a measuring strip 1.

As shown in FIG. 1, a band 1 for measuring blood pressure according to the present invention comprises, for example, a band-shaped band main body 10 (showing the entire band-shaped portion) as a basic member wound around an arm, and an integral part of the band main body 10. And a molded pressure bag body 20. The pressurized bag 20 is a bag-like material that is pressurized and expanded by the introduction of air, acts to press a measurement site for blood pressure measurement, and is a portion that can be said to be a main part of blood pressure measurement.

The feature of the present invention is that the band main body 1
0 is at least a pair of fusible films 13, 15
(Hereinafter, simply referred to as films 13 and 15), and at least one pair of substrates 11 and 17 disposed outside the films 13 and 15, respectively. The film 13 constituting the main body 10,
15 and the base material 11, 17 are formed integrally with the band main body 10.

The bag-like material substantially functioning as the pressurized bag 20 is formed by fusing the at least one pair of films 13 and 15 into a bag-like shape (the fused portion is required to be airtight). It is the part that did. Such a pressurized bag body 20 is used for the band body 1.
0 and is formed integrally with the band main body 10.

Usually, the base materials 11 and 17 are where the skin such as the arm of the person to be measured (measured person) directly touches. In the present invention, except for the fusion-processed portion,
The films 13 and 15 overlap but are not fused and joined (for example, the portions without dots (the portions denoted by reference numerals S1, S2, S3, and S4) in FIG. 1A). Therefore, in the non-fused portion occupying such a large area, that is, substantially the entire band body 10, the texture of the base material is utilized (remains) as it is.

This state will be described in more detail with reference to FIGS. 2 (a) and 2 (b). FIG. 2A is a cross-sectional view showing a state in which the films 15 and 13 and the base material 11 are simply superimposed on the base material 17 in order, and FIG. It is sectional drawing which shows the state which carried out the partial fusion processing.

2 (b), the interface 14a of the films 13 and 15 is welded to each other in a tight and airtight manner. A functionally shaped bag is formed. The interface 16a between the substrate 17 and the film 15 and the interface 12a between the substrate 11 and the film 13 are (i)
The film and the base material are joined to each other firmly in a molten state, or (ii) they are joined with a slight strength in a state where the melt of the film is impregnated in the base material. The state (i) can be exemplified by a case where a nonwoven fabric made of synthetic fiber such as tetron, which can be fused to a film, is used as a base material, and the state (ii) is a state where the base material itself is used. For example, a case where a non-melting cotton fabric is used as a base material can be exemplified.

Further, as described above, the pressurized bag body 20 is composed of the films 13 and 15 and the base materials 11 and
17 and is formed integrally with the band main body 10, and a part of the band main body 10 is a pressure bag 20. In this sense, it can be said that the pressurized bag 20 has both the original function of the pressurized bag and the function of the band.

That is, the blood pressure measurement band 1 of the present invention comprises:
As shown in FIGS. 1 and 2, a base material 17, films 15, 13 and a base material 11 having substantially the entire size of the band main body 10 are sequentially stacked, and then a bag-shaped material as a pressure bag body 20. (FIG. 1)
The pressure bag 20 is formed by fusing the dot area located in the substantially right half of (a). In addition, in order to facilitate the handling of the band main body 10, a predetermined portion of the bag (FIG.
(A dot area located in the substantially left half of (a)) is appropriately fused linearly.

As described above, the blood pressure measurement band 1 of the present invention comprises:
Since a part of the band body 10 can be partially fused (weldged) to form and process the pressurized bag body 20 in the shape of a bag, productivity is extremely good. The pressurized bag 20
In general, a line for introducing or discharging air and a line for detecting pressure in the pressurized bag are connected to communicate with the inside of the pressurized bag 20. These lines can be combined into one, and a combined tube 30 is illustrated in FIG.

In the present invention, the films 13 and 15 constituting the pressurized bag body 20 (the films 13 and 15 constituting one laminated portion of the belt body 10) are made of polyurethane, polypropylene, polyethylene, polyethylene terephthalate, or the like. Ethylene / vinyl acetate copolymer (EVA)
It is desirable to be composed of a material selected from the group consisting of:

A particularly preferred material among these is polyurethane. When a polyurethane is used, the Shore A hardness is 20 to 90, preferably 50 to 80, and the breaking elongation is 200 to 1000%, preferably 400 to 800.
What is% is good. The thickness of the film is 0.01 to 1
mm, preferably 0.03 to 0.5 mm. In particular, those having the above-mentioned physical properties show excellent properties similar to those of latex used in medical practice in hospitals which have been conventionally used. That is, the measurement error is extremely small and the durability is excellent. Gentle to the living body.

To explain this point in detail, polyurethane can maintain a constant elasticity even when the temperature difference is large in summer, winter, etc., so that the measured value is hardly affected by the temperature fluctuation, and the reliability is low. There is a merit of being superior. further,
Since polyurethane is excellent in durability, the change in the measured value is extremely small even if the measurement is repeated tens of thousands of times, and from this point also, the reliability is excellent. From these viewpoints, it can be said that the polyurethane pressure bag 20 is most suitable as the blood pressure measurement band 1 of the blood pressure monitor used in hospitals and the like as a medical practice. In addition, the product of the present invention can be used as a single-use disposable product because the configuration is simple and the cost can be reduced.

Further, polyurethane can be formed into a bag-like material by laminating two film-like materials as in the present invention and then welding (fusing) the same into a predetermined shape, so that the production is simple and the cost can be reduced. Easy to achieve.

Substrates 11, 17 used in the present invention
Preferred examples thereof include nonwoven fabric, cotton fabric, cotton knit, chemical fiber fabric, chemical fiber knit, paper and the like. Substrate 1
In order to improve the feel of 1,17, it is desirable not to impregnate the base material with a new resin component as much as possible. However, in some cases, it is desired to firmly bond with the film. May be impregnated. The thickness of the substrates 11 and 17 is usually about 0.01 to 3 mm.

The band body 10 of the present invention includes a well-known material such as a Velcro (registered trademark) for fully exhibiting the function as a band for a sphygmomanometer and a protective cloth member for protecting the skin. May be attached.

Finally, a device for supplying air to the pressurized bag, a pressure measuring device, various control devices and the like are connected to or incorporated in the band for measuring blood pressure to complete the sphygmomanometer.

The structure of the pressurized bag body 20 according to the present invention, which can make use of the texture of the base material, can be used for other purposes, for example, an air pillow, a cushion, a cushion material for transportation (gap holder).
And the like.
