Description

  The present invention relates to a pressure band for blood pressure measurement that is wound around a pressed site that is a part of a living body and presses the pressed site during blood pressure measurement.

  For example, when a pressure band for blood pressure measurement is wound around a part of a living body whose diameter changes in the longitudinal direction, such as an upper arm or an ankle, various problems occur. For example, in Patent Document 1, as shown in FIG. 1, there are two narrow bands in the width direction that are wound around the outer periphery of the compression band in order to fix the compression band to the pressed portion. It has been proposed that the compression band can be fixed by the narrow band portion corresponding to each of the one end side and the other end side.

1 and 2 of Patent Document 2 show a compression band to be attached to a pressed part such as an arm where the upper arm muscle is raised. The compression band includes a flexible curved plate in which a plurality of slits are formed on both side edges in the axial direction, and the compression band is capable of following the change in the thickness of the pressed portion. It was for improving.
Japanese Patent No. 3638932 Japanese Utility Model Publication 3-47603

  This will be described in detail with reference to FIG. 8 for explaining the compression band of Patent Document 1 and its problems. FIG. 8 schematically shows a cross section in the axial direction when the compression band 200 is wound around a tapered compression part 202 such as an ankle and the expansion bag 204 is inflated with a predetermined pressure at the time of blood pressure measurement. FIG. In FIG. 8, unnecessary members are omitted in order to explain the problem of the compression band 200.

  When the compression band 200 is wound around the tapered compression portion 202 in a cylindrical shape, and the expansion bag 204 accommodated in the outer bag 206 of the compression band 200 is inflated to compress the compression portion 202. Since the reaction force 208 against the compressing force acts on the compression band 200 and the compressed portion 202 is tapered as described above, the reaction force 208 causes the circumference of the compression band 200 to be longer than one end side. A component 210 that moves in the axial direction toward the other short end is applied. Then, the gap A shown in FIG. 8 is generated between the side edge of the flexible restraining plate 212 disposed on the outer peripheral side of the expansion bag 204 and the expansion bag 204 on the other end side. By bending and deforming so that the side edge of the outer bag 206 is close to the expansion bag 204, the outer bag 206 can be deformed so that the outer circumferential side of the outer bag 206 is wound on the inner circumferential side as indicated by an arrow B. Shifts from the initially wound position to the other end side. As described above, the compression band 200 has a problem that its mounting position is shifted.

  Moreover, although the said curved board shape | molded by the cylindrical shape with which the compression band shown by FIG.1 and FIG.2 of patent document 2 has the above slits in the both-sides edge, it is comparatively rigid. This is for making a high curved plate follow a change in the thickness of a pressed part such as an arm. Further, even if the rigidity of both side edges of the curved plate is reduced by the slit, the curved plate is formed in a cylindrical shape for the purpose of facilitating the mounting of the compression band to the pressed portion. For this purpose, it is better that the rigidity of the material of the curved plate is higher to some extent. Therefore, when the compression band is wound around the tapered compression portion and expanded, the edge on the other end side of the curved plate is not sufficiently bent, and the gap A is also generated in the compression band. Therefore, it was not always possible to suppress the displacement of the mounting position.

  An object of the present invention is to provide a pressure band for blood pressure measurement in which the wearing position is prevented from deviating from the initial wound position when wound around the tapered compression target portion of the living body.

The invention according to claim 1 is (a) an inflatable inflatable bag, and a stiffer than the inflatable bag disposed on the outer peripheral side of the inflatable bag in order to suppress expansion to the outer peripheral side of the inflatable bag. Including a flexible restraining plate and an expansion bag and an outer bag for housing the restraining plate, the circumference of one end of which is longer than the circumference of the other end, and is cylindrically formed on the compressed portion of the living body A pressure band for blood pressure measurement that compresses the compressed part by inflating the inflatable bag in a wound state, and (b) axially in a plurality of positions on the other end side edge of the suppression plate (C) When the inflatable bag is inflated, the other end side edge of the restraining plate is pressed against the outer bag, and the other end of the restraining plate is provided. Ri deformable der side side edge to the inner circumferential side, (d) the suppression plate on the one side edge portion thereof said inflatable bladder Characterized in that it is sintered.

  According to a second aspect of the present invention, there is provided a flexible curved plate that is housed in the outer bag so as to be positioned on the outer peripheral side of the suppression plate, and has a cylindrical shape having higher rigidity than the suppression plate. It is characterized by having.

The invention according to claim 3 is characterized in that the curved plate is integrally provided inside the outer bag.

Moreover, in the invention which concerns on Claim 4 , the side edge is curving in the state which expanded the said blood pressure measurement compression band in the plane, and the circumferential length of the one end side is the other end side in the state wound around cylindrical shape It is characterized in that it has a truncated cone shape longer than the circumference.

The invention according to claim 5, wherein the curved plate is comprised of two plates, one plate of which is disposed on the one end side is made into a cylindrical shape, the other plate, The cross section is formed in an elliptical cylindrical shape and is arranged on the other end side.

When the compression band for blood pressure measurement of the invention according to claim 1 is wound around the compressed part of the tapered living body, the compression band tends to shift to the other end side due to the expansion of the expansion bag. Because the inner peripheral surface of the outer bag is pressed against the pressed portion, the friction force generated between the pressed portion and the inner peripheral surface of the outer bag may cause them to slide with each other. However, on the other end side of the compression band, the outer peripheral side of the outer bag tends to be deformed so as to be wound on the inner peripheral side. Moreover, the outer peripheral side of the outer bag moves integrally with the suppression plate by the frictional force generated between them. However, in the pressure band for blood pressure measurement of the invention according to claim 1, notches cut in the axial direction are provided at a plurality of locations on the other end side edge of the suppression plate, and the expansion bag is inflated. In this case, the other end side edge of the restraining plate is pressed against the outer bag, and the other end side edge of the restraining plate can be deformed to the inner peripheral side. Therefore, when the expansion bag is inflated, the other end side edge of the suppression plate is already deformed to the inner peripheral side by being pressed by the outer bag. It is difficult to be further wound on the inner peripheral side, and the restraining plate prevents deformation of the outer bag on the outer peripheral side. As a result, in the compression band, the mounting position is prevented from shifting. Moreover, since the one side edge part is connected with the said expansion | swelling bag and the said suppression board has rigidity higher than the said expansion | swelling bag compared with the said expansion | swelling bag, the said expansion | swelling bag is the said suppression board. It is possible to suppress the expansion bag from being bent in the outer bag.

  In the compression band for blood pressure measurement of the invention according to claim 2, it is accommodated in the outer bag so as to be positioned on the outer peripheral side of the suppression plate, and is formed into a cylindrical shape having higher rigidity than the suppression plate. Since the curved plate is provided, according to the shape of the curved plate, the compression band before mounting is deformed into a cylindrical shape. Therefore, when the compression band is wound around the pressed portion, the work can be easily performed.

According to the blood pressure measurement compression band according to the third aspect of the invention, the curved plate is integrally provided inside the outer bag, so that the position of the curved plate can be maintained.

The pressure band for blood pressure measurement of the invention according to claim 4 is such that the side edge is curved in a state where it is unfolded in a plane, and the circumferential length on one end side is longer than the circumferential length on the other end side when wound in a cylindrical shape. Since it has a frustoconical shape, the compression band can be wound around the compression site following the compression site of the tapered living body.

The blood pressure measurement cuff of the invention according to claim 5, wherein the curved plate is comprised of two plates, one plate of which is disposed on the one end side is made into a cylindrical shape, other Since the plate is formed in a cylindrical shape having an elliptical cross section and is disposed on the other end side, according to the shape of the curved plate, the compression band is deformed into a cylindrical shape on the one end side, and the other On the end side, the cross section is deformed into an elliptical cylindrical shape. Therefore, when the pressed part is the ankle, the compression band is wound so that the one end side is located on the calf side and the other end side is located on the ankle side, thereby imitating the outer shape of the ankle. You can wrap this compression belt.

Example 1
Hereinafter, the compression band 10 of 1st Example of this invention is demonstrated in detail based on drawing. FIG. 1 is a view showing the appearance of the compression band 10. FIG. 2 is a view showing a state in which the outer peripheral side of the compression band 10 is developed. In order to show the internal structure of the compression band 10, the central portion of the drawing is a partial sectional view.

  As shown in FIG. 2, the compression band 10 has a fan-shaped and curved band-like shape in the deployed state, and is for winding around a tapered compression site such as an ankle of a living body. The compression band 10 is an inner winding portion 14 having a width of about 140 mm that is directly wound around the pressed portion, with the surface fastener 12 provided on the outer peripheral surface, with the central portion in the longitudinal direction as a boundary. On the other hand, a cloth that can be attached to the surface fastener 12 is used on the inner peripheral surface thereof, and the width dimension decreases as the distance from the inner winding portion 14 increases, and the width of the tip is about 90 mm. It is the outer winding part 16 for winding. Then, the inner winding portion 14 is placed on the side where the diameter of the tapered portion to be compressed is large, so that one side edge which becomes the large diameter side when being wound in the cylindrical shape of the compression band 10 is located. After being wound around the compressed portion, the outer winding portion 16 is wound around the outer periphery, and the inner peripheral surface of the outer winding portion 16 is attached to the surface fastener 12 so that the compression band 10 is fixed to the pressed portion. . At this time, the compression band 10 has a frustoconical shape in which the circumferential length on one end side is longer than the circumferential length on the other end side, following the shape of the pressed portion.

  As shown in FIG. 2, the exterior of the compression band 10 is constituted by an outer bag 18, and the outer bag 18 has an inner winding part 14 and an outer winding part 16. And the outer bag 18 is sewn together with the outer edge cloth 20 that goes around the outer edge of the cloth that forms the inner peripheral surface and the cloth that forms the outer peripheral surface of the outer bag 18 with the respective outer edges substantially aligned. It is formed in a bag shape. As shown in FIGS. 2 and 3, in the inner winding portion 14 of the outer bag 18, the curved plates 22, 24, the suppression plate 26, and the expansion bag 28 are arranged in this order from the outer peripheral side, so that these 18 is housed.

  The restraining plate 26 is made of a flexible resin such as polypropylene having a thickness of about 1 mm, and has a size that can be accommodated in the outer bag 18 over almost the entire inner winding portion 14 as shown in FIGS. It is a fan-shaped and strip-shaped plate. A plurality of connection holes 30 for connecting the suppression plate 26 and the expansion bag 28 are provided along the side edge of the suppression plate 26 on the one end side of the compression band 10. In addition, a plurality of cutouts 32 are provided on the side edge of the restraining plate 26 on the other end side of the compression band 10.

  As shown in FIGS. 2 and 3, the side edge of the restraining plate 26 provided with the notch 32 is folded back at the tip of the side edge so as to cover the notch 32 from both sides of the restraining plate 26 over the entire length thereof. The elongated cloth 34 is affixed.

  The expansion bag 28 is a fan-shaped belt-like bag having substantially the same outer shape as the suppression plate 26, and is made of a soft resin such as soft polyvinyl chloride having a thickness of about 0.3 mm. Further, the restraining plate 26 is relatively rigid with respect to the expansion bag 28.

  As shown in FIGS. 2 and 3, the side edge of the inflatable bag 28 on the one end side of the compression band 10 has a longitudinal shape 2 that is sufficiently smaller in width than the suppression plate 26 over its entire length. The side edges of the connecting sheets 36 are fused. A plurality of suppression plates 26 are inserted between the connection sheets 36 in a state where the expansion bag 28 and the outer periphery thereof are substantially aligned with each other so as to penetrate through a plurality of connection holes 30 provided in the suppression plate 26. Thus, the connecting sheets 36 are fused to each other. Thereby, the suppression board 26 and the expansion bag 28 are mutually connected.

  Each of the curved plates 22 and 24 has a relatively high rigidity with respect to the restraining plate 26 and is made of a flexible resin such as polypropylene having a thickness of about 1.5 mm. It is a fan-like band-shaped plate that crosses, one of the curved plates 22 having a width dimension of about 50 mm and being arranged on the one end side of the compression band 10, and the other curved plate 24 having a width dimension of about 30 mm. Thus, the compression band 10 is arranged near the other end side at a position not covering the notch 32. A holding sheet 40 made of soft resin such as soft polyvinyl chloride, which is disposed between the curved plates 22 and 24 and the restraining plate 26 and whose outer edge substantially coincides with the inner winding portion 14 of the outer bag 18, and an outer The outer cloth 42 constituting the outer peripheral surface of the inner winding portion 14 of the bag 18 is melted so as to form an elongated fusion margin 44 at a position outside the both side edges parallel to the longitudinal direction of the curved plates 22, 24. By wearing, the curved plates 22 and 24 inserted into the outer cloth 42 and the holding sheet 40 are integrally held by the outer bag 18.

  In addition, the curved plate 22 is formed into a cylindrical shape in advance, and the curved plate 24 is formed into a cylindrical shape having an elliptical cross section. Therefore, as shown in FIG. The one end side has a circular cross section, and the other end side has an oval cross section so as to maintain a substantially cylindrical shape.

  As shown in FIGS. 1 and 2, air is injected into the cylindrical expansion bag 28 inclined to the other end side of the compression band 10 at an elevation angle of about 20 degrees on the outer peripheral side of the central portion of the expansion bag 28. The air injection pipe 46 is provided. The air injection tube 46 passes through the insertion hole 48 provided in the suppression plate 26 shown in FIG. 4, between the two curved plates 22 and 24, and the hole 50 provided in the outer bag 18. It protrudes from the outer peripheral surface of the compression band 10.

  The compression band 10 of the present embodiment has the following effects (1) to (6). (1) FIG. 5 is a diagram schematically showing a cross section in the axial direction when the compression band 10 is attached to a tapered compression site 52 such as an ankle. In FIG. 5, unnecessary members are omitted in order to explain the effects of the first embodiment. As shown in FIG. 5, when the compression band 10 is wound around the tapered compressed portion 52 and the compression band 10 tends to shift to the other end side due to the expansion of the expansion bag 28, the outer bag Since the inner peripheral surface of 18 is pressed against the pressed portion 52, the frictional force generated between the pressed portion 52 and the inner peripheral surface of the outer bag 18 prevents them from sliding against each other, and the compression is performed. On the other end side of the belt 10, as indicated by an arrow J, the outer peripheral side of the outer bag 18 tends to be deformed so as to be wound on the inner peripheral side. Further, the outer peripheral side of the outer bag 18 moves integrally with the restraining plate 26 by the frictional force generated between them. However, in the compression band 10, notches 32 cut in the axial direction are provided at a plurality of locations on the other end side edge of the suppression plate 26, and when the expansion bag 28 is inflated, the suppression plate 26. The other end side edge is pressed by the outer bag 18, and the other end side edge of the restraining plate 26 can be deformed to the inner peripheral side. Therefore, when the expansion bag 28 is inflated, the other end side edge of the suppression plate 26 is already deformed to the inner peripheral side by being pressed by the outer bag 18, and from this state, the suppression plate 26 is It is difficult to be further wound on the inner peripheral side, and the restraining plate 26 prevents deformation of the outer bag 18 on the outer peripheral side. As a result, in the compression band 10, it is possible to prevent the mounting position from being shifted.

  The above-described effect produced by the compression band 10 will be described in more detail. A plurality of notches 32 are provided on the side edge of the suppression plate 26 on the other end side of the compression band 10, and the thickness of the suppression plate 26 is as thin as about 1 mm. The side edges are sufficiently flexible. The curved plate 24 inserted between the outer cloth 42 and the suppression plate 26 is disposed so as not to cover the notch 32. Therefore, as shown in FIG. 5, when the compression band 10 is wound around the tapered compressed portion 52 and the expansion bag 28 is inflated, the side edge of the suppression plate 26 by the outer cloth 42 on the other end side is It is pressed toward the expanded bag 28 and deformed toward the pressed portion 52 so as to be in close contact with the expanded bag 28, and no gap is generated between the side edge and the expanded bag 28. Then, since the side edge of the restraining plate 26 that is deformed so as to be in close contact with the expansion bag 28 is higher in rigidity than the expansion bag 28, it exceeds the other end side of the expansion bag 28 having a small curvature radius. It cannot be deformed so as to be wound from the outer peripheral side to the inner peripheral side, and the restraining plate 26 prevents deformation of the outer bag 18 on the outer peripheral side. As a result, in the compression band 10, it is suppressed that the mounting position shifts.

  (2) The flexible curved plates 22 and 24 are formed in advance so as to have a cylindrical shape similar to that of the compression band 10 after winding. Therefore, as shown in FIG. The part 14 is configured to maintain a substantially cylindrical shape. Therefore, when the compression band 10 is wound around the predetermined pressed portion 52, the operation can be easily performed.

  (3) In the compression band 10, one side edge portion of the suppression plate 26 is connected to the expansion bag 28 via the connection sheet 36, and the suppression plate 26 is relatively rigid compared to the expansion bag 28. Since it is high, the expansion bag 28 is accommodated in the outer bag 18 along the suppression plate 26, and the expansion bag 28 can be prevented from being bent in the outer bag 18.

  (4) In the compression band 10, the curved plates 22 and 24 are inserted into the outer cloth 42 and the holding sheet 40 and are integrally provided inside the outer bag 18. Can be held. Further, since the curved plate 24 is disposed so as not to cover the notch 32 of the suppression plate 26, the other side edge of the suppression plate 26 is expanded by the outer cloth 42 when the expansion bag 28 is expanded. The curved plate 24 does not prevent it from being pressed against the expansion bag 28.

  (5) Since the compression band 10 has a fan-shaped and curved band shape in the unfolded state, the circumferential length of one end side of the compression band 10 is the other end side when wound in a cylindrical shape. Therefore, the compression band 10 can be wound around the compressed portion 52 following the tapered compressed portion 52.

  (6) In the compression band 10, the curved plate 22 is formed in a cylindrical shape in advance, and the curved plate 24 is formed in a cylindrical shape having an elliptical cross section. The one end side has a circular cross section, and the other end side has an elliptical cross section. Therefore, when the pressed part 52 is an ankle, the curved plate 22 is located on the calf side and the curved plate 24 is located on the ankle side. Thus, the compression band 10 can be wound.

  As shown in FIG. 6, the compression band 70 is obtained by removing the curved plates 22 and 24 and the holding sheet 40 for holding the same in the outer bag 18 from the compression band 10 according to the first embodiment. Therefore, the configuration of the members other than these two points in the compression band 70 is the same as that of the compression band 10.

  Since the compression band 70 of this embodiment is obtained by removing the curved plates 22 and 24 and the holding sheet 40 from the compression band 10, as shown in FIG. When the inflatable bag 28 is inflated, the side edge having the notch 32 of the restraining plate 26 is deformed so as to be in close contact with the inflatable bag 28 on the other end side of the compression band 70 as well as the compression band 10. Similarly to the effect (1) of the compression band 10, the compression band 70 is prevented from shifting its mounting position. Similarly to the compression band 10, in the compression band 70, the suppression plate 26 has one side edge portion connected to the expansion bag 28 via the connection sheet 36, and is a fan-shaped and curved band shape in the expanded state. Since the compression band 70 has the shape, the compression band 70 exhibits the same effects as the effects (3) and (5) of the compression band 10.

  As mentioned above, although the Example of this invention was described in detail based on drawing, this is an embodiment to the last, and this invention is applied also in another aspect.

  For example, in the first embodiment described above, the curved plates 22 and 24 are inserted into the outer cloth 42 and the holding sheet 40 and fused together to be held integrally with the outer bag 18. The holding method may be other methods such as bonding the curved plates 22 and 24 to the outer bag 18. Further, the curved plates 22 and 24 may be held against the restraining plate 26 instead of the outer bag 18.

  In the second embodiment, the inner plate of the compression band 70 is deformed into a cylindrical shape by bending the suppression plate 26 into a cylindrical shape in advance, and the compression is applied to a portion to be compressed such as an ankle. It is also possible to facilitate the wearing of the band 70.

  Further, the compression bands 10 and 70 of the above-described embodiment are fan-shaped and curved bands in the deployed state, but may be linear band-shaped compression bands.

  In the above-described embodiment, the ankle is mentioned as an example of the pressed part 52, but the pressed part 52 may be another part such as the upper arm.
