Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a blood pressure measuring compression band that is wound around a part of a living body when measuring blood pressure.

[0002]

[Prior art]

 When measuring the blood pressure value of a living body, in order to compress the artery of the living body, a blood pressure measuring compression band having an inflatable bag-like part to which pressurized gas is supplied is wrapped around a part of the living body. . Conventionally, the above-described compression band has been configured by providing an expansion bag made of rubber or the like inside a bag-shaped portion provided on a band-shaped cloth.

[0003]

[Issues to be solved by the device]

 By the way, in the medical field, it is often necessary to continuously monitor the blood pressure value of the patient.In such a case, the compression band is wound around a part of the patient's body, such as the upper arm. The bag-shaped part expands and contracts repeatedly over a long period of time as it is. However, at this time, a streak-like streak that is parallel to the width direction of the compression band may occur on a part of the body of the patient on which the compression band is wound. It is considered that this blood stasis occurs due to the following reasons. That is, the compression band is unavoidably thickened to some extent because a rubber bag or the like is provided inside the bag-shaped portion. Moreover, since the length of the surface on the outer circumference side of the compression band and the length of the surface on the inner circumference side are substantially equal when wound, the inner circumference of the compression band when wound There is a difference in radius between the side and the outer side, that is, a difference in perimeter depending on the thickness of the compression band. Therefore, since the compression band has a large difference in the peripheral length in a wound state, the inner peripheral side of the bag-shaped portion and the inner peripheral side of the inflatable bag are largely undulated in the circumferential direction. . Therefore, when the inflatable bag is inflated, the inwardly convex portion of the inner circumferential side that is wavy is preferentially inflated, resulting in a relatively sharp angle between the adjacent convex portions. A valley is formed. At this time, the inner peripheral side of the bag-shaped part is deformed so as to form a relatively acute-angled valley following the inner peripheral side of the inflatable bag. Is considered to occur.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a compression band for blood pressure measurement in which blood stasis hardly occurs even when blood pressure is continuously measured for a long time. There is something to do.

[0005]

[First means for solving the problem]

 In order to achieve such an object, the gist of the first invention is a compression band that has an inflatable bag-like portion and is wound in a cylindrical shape to press a part of a living body when measuring blood pressure. That is, the expansion bag is provided inside the bag-shaped portion, and the inside of the bag-shaped portion and the expansion bag are made airtight.

[0006]

[Operation and effects of the first device]

 In this way, since the expansion bag is provided inside the bag-shaped part, when pressure air is supplied to the compression band wrapped around a part of the living body when measuring blood pressure, only the expansion bag is Is inflated. At this time, since the inside of the bag-like part and the inflatable bag are made airtight, when pressurized air is supplied to inflate the inflatable bag, the part located on the outer peripheral side of the inflatable bag and the bag-like part is expanded. The air existing between the bag and the bag moves between the inner peripheral side of the bag-shaped portion and the inflatable bag. Therefore, when the inflatable bag is inflated, the portion located on the inner peripheral side is deformed so that a relatively acute-angled valley is formed due to the corrugation in the wound state as described above. Also in the case, the portion located on the inner peripheral side of the bag-shaped portion is prevented from being deformed following the expansion bag due to the presence of air between the bag and the expansion bag. Therefore, the condition that part of the skin of the living body is removed is suppressed, and even when blood pressure is continuously measured for a long period of time, blood stasis is less likely to occur, and pain to the living body is reduced. .

[0007]

[Second means for solving the problem]

 In order to achieve the above-mentioned object, the gist of the second invention is that a compression band that has an inflatable bag-like portion and is wound in a cylindrical shape to compress a part of a living body when measuring blood pressure is used. The part of the bag-shaped part located on the outer peripheral side when formed into the cylindrical shape is made of a slightly elastic material.

[0008]

[Operation and effect of second device]

 In this way, the portion of the compression band located on the outer peripheral side when wound around a part of the living body is made of a slightly elastic material, so that a part of the living body is measured when measuring blood pressure. When the compressed air is supplied to the compression band wound around and the bag-shaped portion is inflated, the portion located on the outer peripheral side is slightly elongated in the longitudinal direction of the compression band. Therefore, the wavy state on the inner peripheral side of the bag-shaped portion and the inflatable bag due to the difference in radius when wound as described above is alleviated, and formation of an acute valley is suppressed. Therefore, it is possible to prevent the skin of part of the living body from being plucked, making it less likely to cause blood stasis even when blood pressure is measured continuously for a long period of time, which reduces the pain to the living body. It will be released.

【Example】

 An embodiment of the present invention will be described below in detail with reference to the drawings.

FIG. 1 and FIG. 2 are views showing both sides of a blood pressure measurement arm band 10 which is one embodiment of the present invention, and FIGS. 3 and 4 are views schematically showing the cross-sectional structure thereof. The arm band 10 has a band shape with a length of about 50 cm, a width of about 14 cm, and a thickness of about 1.5 mm, and one long side 12 is connected to a pressure air supply / discharge device (not shown) at the time of measurement. A supply / discharge pipe 14 is provided. The armband 10 includes an outer peripheral member 16 having an outer peripheral surface 15 which is an outer peripheral side when made into a cylindrical shape when measuring blood pressure, and an inner peripheral member 18 having an inner peripheral surface 17 which is an inner peripheral side. As shown in the cross section in the short side direction in FIG. 3, the long side 12 side is bonded to the outer peripheral side member 16 side at a folded portion 20 formed along the long side 12 of the inner peripheral side member 18 side. At the same time, thermocompression bonding is performed on the opposite long side 22 side, both short sides 24, 26 side, and the seal portions 28, 30, 32, 34 provided in parallel with the short sides 24, 26 at intermediate positions in the longitudinal direction. By doing so, it is formed into a closed bag shape. In the present embodiment, the arm band 10 corresponds to a blood pressure measurement compression band.

As shown in FIG. 3, an expansion bag 40 is provided in the internal space 38 of the expansion part 36 defined by the folded-back part 20 and the seal parts 28, 30, 34. This inflatable bag 40 has, for example, high tensile strength and tensile elongation, and has a finely embossed ethylene vinyl acetate resin (composition: vinyl acetate 15 to 20%, LDPE [linear low-density polyethylene: Linear low-density polyethylene] 85-80%) with a thickness of about 0.02 mm is bent along the long side 12 side, and when the outer peripheral side member 16 and the inner peripheral side member 18 are thermocompression bonded. The seal portions 28, 30, 34 are thermocompressed at the same time to form a closed bag shape. The supply / discharge pipe 14 is inserted into through holes 42 and 44 provided in the inner peripheral member 18 and the expansion bag 40, respectively, and is fixed by thermocompression bonding. Therefore, the expansion bag 40 is not restricted in any part other than the seal parts 28, 30, 34 and the fixed part of the supply / discharge pipe 14, for example, the surface 45, and the internal space 38 allows air to remain therein. It is airtight so that the air does not leak outside. As shown in FIG. 4, the expansion bag 40 has a length ranging from the seal portion 30 to the seal portion 34, and the range defined by the folded-back portion 20 and the seal portions 28, 32 and 34 is It is composed of only the outer peripheral side member 16 and the inner peripheral side member 18. In the present embodiment, the inflatable portion 36 corresponds to an inflatable bag-shaped portion.

The outer peripheral side member 16 is composed of a first layer 46 made of polyethylene resin having a thickness of 0.04 mm from the inside, for example, a second layer made of cloth in which medium and low pressure polyethylene fibers are woven at a driving density of 10 × 10 / inch. The layer 48, the third layer 50 of the same material and thickness as the first layer 46, and the yarn weight of 40/20 are used and the basis weight is set to 65 g / m ^2, and the loop-shaped fibers are exposed on one side and in the longitudinal direction. It is composed of four layers of an outer peripheral layer 52 made of a nylon pile having wavy fibers, which are in close contact with each other. The first layer 46 and the second layer 48 are for increasing the tensile strength so that the outer peripheral member 16 is not damaged even when the inflation bag 40 is inflated at the time of blood pressure measurement and a pressure is generated in the outer circumferential direction. belongs to. Further, the inner peripheral side member 18 is, for example, an inner peripheral layer 54 made of a non-woven fabric having a thickness of 0.55 mm and a mixed yarn of 50% rayon and 50% polyester having a basis weight of 60 g / m ² . It is composed of two layers in which a backing layer 56 made of a polyethylene resin having a thickness of 05 mm is adhered to each other. Therefore, the outer peripheral side member 16 and the inner peripheral side member 18 can be slightly expanded and contracted by the above-mentioned wavy fiber or nonwoven fabric in the longitudinal direction and the polyethylene layer closely adhered while maintaining the airtightness of the internal space 38. It is configured to be possible. Therefore, when it is used for blood pressure measurement as described later, when pressurized air is supplied to the expansion bag 40 and the internal pressure of the expansion section 36 is 250 to 300 mmHg, the difference in diameter in the wound state is A slight amount of expansion occurs in the outer peripheral member 16 to such an extent that the resulting waviness of the inner peripheral member 18 is relaxed. 3 and 4 are views for explaining the inside of the armband 10, and the dimensional ratio of each part is not always accurate.

Returning to FIG. 1, on the surface of the outer peripheral layer 52 of the outer peripheral member 16, that is, on the outer peripheral surface 15, a measuring scale 58 is provided at a predetermined portion in the longitudinal direction at a portion close to the long side 22 of the intermediate portion in the longitudinal direction. It is provided over the length. The measuring scale 58 has short scales parallel to the short side, which are engraved at intervals of 1 cm, and beside the scale, one end 60 in the longitudinal direction including the short side 26 ends the winding. When the band 10 is wrapped around a part of a living body, the unit of cm is from 13 (cm) to 35 (cm) so that the scale of the portion where the short side 26 is located becomes the perimeter of the part of the living body. ) Numbers are attached.

Further, a winding scale 62 is provided on the side of the scale of 24 (cm) to 33 (cm) of the measuring scale 58 and slightly to the right of the center in the short side direction. . The winding scale 62 is engraved at a slightly smaller interval than the measuring scale 58, and the scale corresponding to 24 (cm) is parallel to the short side 26 of the 24 (cm) scale of the measuring scale 58. It is on an extension of the direction. For other scales corresponding to 25 (cm) to 33 (cm), the larger the number is, the larger the angle θ formed by the line parallel to the short side 26 becomes, and the scale part of 33 (cm) For example, an extension line of each graduation indicated by a dot-dash line and an extension line of the measurement graduation 58 of the same number scale in a direction parallel to the short side 26 intersect at a point 64 on the long side 22, It is slanted with respect to a line parallel to the short side 26.

Between the measuring scale 58 and the winding scale 62, a bending position indicating line 66 extending from the short side 24 to the short side 26 is parallel to the long side 22 and long. It is provided at a position separated from the side 12 by 8 to 9 cm. In addition, at both ends in the longitudinal direction between the long side 22 and the bending position indicating line 66, one side of the magic tape defined in JIS L0213 is configured, for example, a side surface in FIG. As shown, bending fastener pads 70 and 72 each having a large number of hook-shaped portions 68 are fixed to one surface, and the back surface of the end portion 60 is substantially entirely covered with one surface as shown in FIG. A winding fastener pad 76 having a large number of hook-shaped portions 74 is fixed. The arrow 78 indicates the position in the circumferential direction when wound around a part of the living body when measuring the blood pressure. Further, the measuring scale 58, the winding scale 62, the bending position indicating line 66 and the arrow 78 are all directly printed and provided on the outer peripheral layer 52 of the outer peripheral member 16.

When the blood pressure is measured, the armband 10 configured as described above is used by being wound around a part of the body, for example, the upper arm 80, as shown in FIG. The winding work will be described below. The armband 10 has the long side 22 on the shoulder side (that is, the upstream side of the artery) and the long side 12 to which the supply / discharge pipe 14 connected to a pressure air supply / discharge device (not shown) is fixed, and the elbow side (that is, the downstream side). ), The outer peripheral surface 15 is on the outside and the short side 26 is the end, and the short side 24 is wrapped around the upper arm portion 80, and the number on the measuring scale 58 indicated by the short side 26 is read. At this time, the winding is performed with the long side 22 positioned in one plane over the entire length so that the shoulder side and the elbow side have the same diameter. If the read number is 24 to 33, the diagonally extending line of the winding scale 62 corresponding to the number (for example, one point corresponding to 33 (cm) of the winding scale 62 in FIG. 1) While fixing the point located on the shoulder side of the short side 26 so that the broken line) and the short side 26 match, the winding diameter of the long side 12 located on the elbow side is changed, and the winding fastener pad 76 is attached. It is attached and fixed to the outer peripheral layer 52. At this time, the position of the upper arm portion 80 of the arm band 10 in the circumferential direction is performed by aligning the arrow 78 on the artery. This circumferential position is also similarly positioned when the read scale, which will be described later, is 14 to 23. In FIG. 5, reference numeral 81 is a microphone for detecting Korotkoff sounds.

When the read number is 34 or more or 13 or less, the arm band 10 is unsuitable for measuring the blood pressure of a part of the living body, and therefore an arm band of another size is used. That is, the "use for oversize" marked on the right side of the scale 34 is because the circumference of the upper arm 80 is too large and the width of the arm band 10 is insufficient, so that normal blood pressure values cannot be measured. , “Use for newborn baby” that is marked on the right side of the scale 13 is for encouraging the use of an oversized arm band, and the perimeter of the upper arm portion 80 is too small and the arm band 10 has a large width. In other words, since it is not possible to measure the normal blood pressure value again, it encourages the use of neonatal arm girdle.

Even when the read number is 14 to 23, the width of the arm band 10 is too large. In this case, the arm band 10 is bent along the bending position indicating line 66 and is folded. Bending fastener pads 70 and 72 are attached to the outer peripheral surface 15, and the width of the armband 10 is set to the length from the long side 12 to the bending position indicating line 66, that is, 8 to 9 cm, as shown in FIG. Used in the state. Since each of the fastener pads 70, 72, and 76 has a large number of hook-shaped portions 68 or 74, the loop-shaped fibers of the outer peripheral layer 52 made of nylon pile have a hook-shaped portion 68 or 74. When the tip end is caught, it is fixed in a wound state or a bent state.

After the armband 10 is wound around the upper arm portion 80 as described above, pressure air is supplied from the pressure air supply / discharge device (not shown) to the space 82 inside the expansion bag 40 via the supply / discharge pipe 14. Is supplied and the inflatable bag 40 is inflated toward the inner peripheral side, whereby the inner peripheral surface 17 is moved inward and the upper arm 80 is compressed, as shown in FIG. 7, and the blood pressure value is measured. Done. Note that the blood pressure measurement process is well known and is not always necessary for understanding the present proposal, and therefore its description is omitted. Further, in FIG. 7, the upper arm portion 80 is omitted, and the left half surface of the figure shows a non-expanded state and the right half surface shows an expanded state.

Here, in the present embodiment, when the armband 10 is wound around the upper arm 80 during blood pressure measurement, the measuring scale 58 provided along the long side 22 located on the shoulder side is used. The perimeter of the upper arm 80 is obtained. By fixing the arm band 10 according to the winding scale 62 corresponding to the obtained perimeter, the upper arm part 80 is tightened with a uniform and appropriate pressure over the entire length of the part around which the arm band 10 is wound. . Therefore, the arm band 10 can be appropriately wound without requiring special skill, and a reliable blood pressure value can be easily obtained. The intervals between the wrapping scales 62 are set based on the empirical fact that generally, the larger the developed arm, the larger the difference in the perimeter between the shoulder side and the elbow side (the shoulder side is larger). Therefore, the angle θ formed by the winding scale 62 and the short side 26, that is, the deviation between the measuring scale 58 and the winding scale 62 is increased as the number increases. When measuring the blood pressure, normal measurement cannot be performed unless the entire surface of the arm band 10 is evenly wound around the upper arm portion 80. When wrapped around a thick upper arm 80, etc., with different perimeters on the shoulder side and elbow side, as shown in Fig. 5, the compression band 10 is made into a truncated cone shape according to the shape, and the entire strength is uniform. It is necessary to be wound so that it will be, but conventionally, skill was required for such work. According to the present embodiment, as a result of the above, the armband 10 can be easily wrapped around the upper arm 80 without requiring special skill. Although there is no wrapping scale 62 corresponding to 23 (cm) or less of the measuring scale 58, in general, in the case of such a thin arm, the difference in the circumferential length between the shoulder side and the elbow side is It is small and winding work is not particularly difficult.

In addition, the armband 10 is provided in the internal space 38 between the outer peripheral side member 16 and the inner peripheral side member 18 in the inflatable portion 36, in a state where the surface 45 of the inflatable bag 40 is not restrained at all. The compressed air is supplied only to the expansion bag 40. When measuring the blood pressure, the arm band 10 is wound around the upper arm portion 80, but the outer circumferential side member 16 and the inner circumferential side member 18 have substantially the same longitudinal dimension, and thus the wound state is shown. 7, the inner peripheral surface 17 and the inner peripheral surface 83 of the inflatable bag 40 are wavy in the circumferential direction. Then, in the expanded state shown on the right half surface, the portion of the corrugated shape located relatively on the inner peripheral side is preferentially expanded to the inner peripheral side, and an acute-angled valley is formed in the inflatable bag 40. At this time, the conventional arm band 84 in which a rubber bag or the like is used instead of the inflatable bag 40 has large corrugations in the non-inflated state because the whole is thickened, and the inner peripheral member 18 Is deformed following the inner peripheral surface 85 of a rubber bag or the like, so that a sharp angled portion 86 is formed as shown in FIG. was there. On the other hand, according to this embodiment, since the internal space 38 is made airtight, when pressurized air is supplied and the expansion bag 40 is inflated, the air existing on the outer peripheral side member 16 side in the internal space 38. Moves to the inner peripheral member 18 side. Therefore, when the inflatable bag 40 is inflated, when the inner peripheral surface 83 is deformed so as to form a relatively acute-angled valley due to the waviness of the wound state as described above. However, the inner peripheral member 18 is restrained from being deformed following the inner peripheral surface 83 of the expansion bag 40 due to the presence of the air in the internal space 38. Further, since the outer peripheral member 16 is configured to be slightly expandable and contractible, when the inflatable bag 40 is inflated, it is slightly extended in the longitudinal direction of the compression band, and when it is wound as described above. The wavy state of the inner peripheral member 18 and the inner peripheral surface 83 of the expansion bag 40 due to the difference in radius is relaxed, and formation of an acute-angled valley is suppressed. Further, since the inflatable bag 40 is extremely thin, the entire arm band 10 is thinned so that the unevenness of the corrugations in the non-inflated state is reduced. Therefore, as shown in the right half surface of FIG. 7, no acute angle is generated on the inner peripheral surface 17, and stasis spots are unlikely to occur. Therefore, even when the measurement is repeated for a patient who needs continuous blood pressure monitoring for a long time, the blood stasis hardly occurs and the patient is less likely to suffer pain.

Also, when measuring the blood pressure value of a child with a thin upper arm 80, the arm band 10 is bent with the bending position indicating line 66 as a reference and fixed with the fastener pads 70 and 72, as shown in FIG. By setting the state as shown, the armband 10 of this embodiment can be used. When measuring the blood pressure, the width of the arm band 10 is determined to be within a predetermined range according to the diameter of the upper arm 80, so the arm band 10 having a width corresponding to the diameter of the upper arm 80 is usually prepared. There is a need to. Since the arm band that used a conventional rubber bag or the like has a large thickness, it cannot be bent and used as described above, but according to the present embodiment, the entire arm band 10 is thinned and expanded. Since the bag 40 is very thin, it can be folded and pressurized air cannot be supplied to the folded portion (that is, the portion between the folding position indicating line 66 and the long side 22). Therefore, the armband 10 can be used both for general use and for children, and the versatility is enhanced.

Further, according to this embodiment, since the inner peripheral layer 54 of the inner peripheral member 18 is made of non-woven fabric, an air layer is formed between the arm band 10 and the upper arm 80 even in a wound state. Is present, and stuffiness does not easily occur even when worn for a long period of time, and there is little distress to the patient.

Further, according to the present embodiment, since the outer peripheral layer 52 of the outer peripheral member 16 is made of nylon pile, the hook-shaped portions of the fastener pads 70, 72, 76 in the magic tape specified in JIS L0213. It is not necessary to use a member having loop-shaped portions corresponding to 68 and 74, and the thickness of the arm band 10 is further reduced.

Further, since the armband 10 of this embodiment is made of nylon pile, non-woven fabric, polyethylene, and ethylene vinyl acetate resin, harmful combustion gas is hardly generated when incinerated. Therefore, it is useful as a disposable armband in a use situation where it is desired to replace the armband 10 for each patient.

Although one embodiment of the present invention has been described in detail above with reference to the drawings, the present invention can be implemented in still another mode.

For example, in the above-described embodiment, both sides of the expansion bag 40 are unconstrained, and an airtight internal space 38 is formed between the outer peripheral side member 16, the inner peripheral side member 18, and the expansion bag 40. Although it is formed, it is not always necessary, and for example, an airtight space may be formed between the inner peripheral side member 18 and the inflation bag 40. Although both the outer peripheral member 16 and the inner peripheral member 18 are configured to be expandable and contractible, the inner peripheral member 18 may not necessarily be expandable and contractable. Furthermore, the object of the present invention can be achieved even if only one of these airtight space and elasticity is provided. Although the expansion bag 40 is formed to be extremely thin, it may be thick. Further, in the embodiment, by embossing the surface of the expansion bag 40, the relative movement between the expansion bag 40 and the inner peripheral member 18 is easily caused, but the relative movement such as embossing is not always easy to occur. No means to do it is necessary.

Further, in the above-described embodiment, the case where the present invention is applied to the armband 10 suitable for disposable use has been described, but the present invention forms the airtight internal space 38 or the outer peripheral side member 16 It is configured to be expandable and contractible to prevent blood spots and is not limited to disposable armbands.

Further, the present invention is not limited to the arm band 10 used for the upper arm 80 described in the embodiments, but is also applicable to a compression band used for other parts of the living body. In that case, the distance between the wrapping scales 62, the inclination with respect to the short side 26, and which range of the scales 58 to be provided with the scales, etc. are appropriately determined according to the part of the living body where the blood pressure is measured. It will be changed.

Further, the measuring scale 58, the winding scale 62, the bending indicator line 66, the fastener pads 70, 72 and the like are not necessarily provided.

Although not illustrated one by one, the present invention can be variously modified without departing from the spirit thereof.
