Detailed Description
Hereinafter, an embodiment of a sphygmomanometer cuff according to the present invention will be described based on a first embodiment shown in the drawings.
(first embodiment)
The sphygmomanometer cuff according to the first embodiment is applied to an arm band as a sphygmomanometer that is wound around an arm of a subject to measure a blood pressure.
[ constitution of arm Belt ]
Fig. 1 is a schematic view showing a state in which an arm band for a sphygmomanometer according to a first embodiment is wrapped around an arm of a subject. Fig. 2 is a perspective view showing a state in which the arm band of the first embodiment is wound in the winding direction (a wound-up state). Fig. 3 is an exploded perspective view showing a state where the arm band of the first embodiment is flattened. Fig. 4 is a sectional view showing an arm band of the first embodiment. Fig. 5 is a perspective view showing a core material of the first embodiment. The structure of the arm band of the first embodiment will be described below with reference to fig. 1 to 5.
As shown in fig. 1, the arm band 1 is wound around an arm M of a subject to be examined of a subject. As shown in fig. 2 and 3, the arm band 1 includes: a hood 20 formed in a band shape and having a winding direction P longer than a width direction D; a core material 30 housed inside the hood 20; an airbag 40 as a fluid bag housed inside the hood portion 20; and a separator 10 separating the core material 30 from the airbag 40.
As shown in fig. 3 and 4, the cover 20 includes: an outer cloth 21 disposed on the outer peripheral side in a state of being wound around the arm M; and a back portion 22 disposed on the inner peripheral side and contacting the arm M.
The outer cloth 21 may be, for example, a polyester cloth. The outer cloth 21 is composed of a first outer cloth 21a and a second outer cloth 21 b. The first outer cloth 21a and the second outer cloth 21b are formed in a band shape. An end portion of one side of the winding direction P of the first outer cloth 21a and an end portion of the other side of the winding direction P of the second outer cloth 21b are sewn together to form one outer cloth 21.
The lining 22 may be, for example, nylon cloth. The inner cloth 22 is composed of a first inner cloth 22a and a second inner cloth 22 b. The first and second back cloths 22a and 22b are formed in a band shape.
As shown in fig. 2, an annular female surface fastener 27 is formed on the entire surface of the second back fabric 22b of the back fabric 22. Hook-shaped male surface fasteners 26 are formed on the first outer fabric 21a of the outer fabric 21.
The core material 30 is formed of a sheet material having elasticity such as polypropylene (PP). The core member 30 is formed in a rectangular plate shape slightly smaller than the first inner fabric 22 a. As shown in fig. 5, the core 30 is formed in a substantially cylindrical shape in which the plate material is bent in the winding direction P. As shown in fig. 3 and 4, the core material 30 is accommodated between the first outer cloth 21a and the separator 10.
Since the core material 30 is accommodated inside the cover portion 20, the arm band 1 is wound along the shape of the substantially cylindrical core material 30 within the range in which the core material 30 is accommodated, as shown in fig. 2. The inner diameter of the arm band 1 wound in a substantially cylindrical shape is formed to be slightly smaller than the thickness of the arm M of an average adult by the core member 30.
The airbag 40 is made of, for example, polyvinyl chloride (PVC), and is formed in a rectangular bag shape of a two-layer structure in which two bag bodies are stacked. As shown in fig. 3 and 4, the airbag 40 is disposed on the inner peripheral side of the core 30. The air bag 40 is accommodated between the first inner cloth 22a and the separator 10. That is, the core material 30 and the airbag 40 are partitioned by the separator 10.
As shown in fig. 1 and 2, air tube 50 is connected to balloon 40, and supplies air through air tube 50 to the interior of balloon 40, thereby inflating balloon 40. In contrast, emanation through the air tube 50 discharges air from the inside of the airbag 40, and the airbag 40 contracts.
In the contracted state, as shown in fig. 3, for example, the airbag 40 is provided in the same range as the range in which the core material 30 is disposed. In the contracted state, the airbag 40 is creased at the edge 41 in the width direction D.
When the arm band 1 configured as described above is attached (worn) on the arm M, the end portion of the arm band 1 wound around the core member 30 in the winding direction P is opened, and the arm band 1 is wound around the arm M and attached. At this time, the arm band 1 presses the inner side of the arm M by the load due to the elastic force of the core member 30. Then, due to the load, a frictional force in the circumferential direction of the arm M is generated between the back cloth 22 and the surface of the arm M.
Therefore, when the subject himself/herself mounts the curled portion (the curled portion) of the arm band 1 on the arm M of one hand and winds the remaining portion of the arm band 1 with the other hand, the mounted portion can be prevented from rotating without pressing the arm band 1 with one hand because of the frictional force in the circumferential direction between the already mounted portion (the curled portion of the arm band 1) and the arm M, and the subject himself/herself can be easily mounted. In the state where the arm band 1 is wound around the arm M, the female surface fastener 27 and the male surface fastener 26 are bonded to each other, and the state where the arm band 1 is wound around the arm M is maintained.
[ constitution of the separator ]
Fig. 6 shows a top view of the separator 10 of the first embodiment. The structure of the separator 10 according to the first embodiment will be described below with reference to fig. 6.
As shown in fig. 6, the separator 10 has a slit 15, and the slit 15 is a cut from a rectangular sheet material in the vicinity of the center in the winding direction P at the edges 14 on both sides in the width direction D. In other words, the separator 10 is formed to have the slits 15 cut from the rectangular sheet near the center of the edges 14 on both sides in the winding direction P. The notch 15 may be provided at the edge 14 in either one of the width directions D.
Due to the presence of the cut 15, the separator 10 is formed by a first end piece 11 as an end piece, a second end piece 12 as an end piece, and a narrow portion 13 connecting the first end piece 11 and the second end piece 12.
The first end piece 11 is provided at an end portion on one side of the winding direction P of the separator 10. The second end member 12 is provided at the end of the other side of the separator 10 in the winding direction P.
The narrow-width portion 13 is formed to have a width smaller than the widths of the first and second end members 11 and 12. The narrow portion 13 is formed at substantially the center in the width direction D of the first end member 11 and the second end member 12, and both ends in the width direction D are formed as cutouts 15. The narrow-width portion 13 extends from the base end 11c of the first end piece 11 in the winding direction P. The narrow-width portion 13 extends from the base end 12c of the second end piece 12 in the winding direction P. That is, the narrow-width portion 13 connects the base end 11c of the first end piece 11 and the base end 12c of the second end piece 12.
The side 11a of the first end piece 11 that connects with the narrow-width portions 13 is inclined and forms an obtuse angle with the side of the edge of the corresponding narrow-width portion 13 in the width direction D. The side 12a of the second end piece 12 that connects with the narrow-width portions 13 is inclined and forms an obtuse angle with the side of the edge of the corresponding narrow-width portion 13 in the width direction D.
The side 13a of the narrow-width portion 13 is provided with an R-shaped portion 11b, and the R-shaped portion 11b is smoothly connected to the side 11a of the first end member 11 connected to the narrow-width portion 13. The side 13a of the narrow-width portion 13 is provided with an R-shaped portion 12b, and the R-shaped portion 12b is smoothly connected with the side 12a of the second end piece 12 connected to the narrow-width portion 13.
The separator 10 configured as described above prevents the back cloth 22 from being deformed when the edge of the core material 30 in the winding direction P protrudes toward the inner circumferential side. That is, the back cloth 22 is formed of a relatively soft material since it has a portion that contacts the arm M. When the arm band 1 is wound around the arm M, the bent shape of the core material 30 is unfolded against the elastic force of the core material 30, but the core material 30 tries to return to the bent state (wound state) by the elastic force.
Therefore, the edge of the core material 30 protrudes inward in the radial direction. At this time, in the arm band 1 including the separator 10, the edge of the core member 30 presses the back cloth 22 inward in the radial direction, and the back cloth 22 made of a soft material is pressed inward in the radial direction and stretched to be deformed. However, in the arm band 1 including the separator 10, the edge of the core member 30 is received (blocked) by the separator 10, and thus the back cloth 22 is prevented from being deformed.
Since the separator 10 is formed of a material harder than the lining 22 to receive displacement of the edge caused by the elastic force of the core material 30 to prevent and suppress the extension of the lining 22.
[ manufacturing method of arm Belt ]
Fig. 7 and 8 are diagrams for explaining a method of manufacturing the arm band 1 according to the first embodiment. Hereinafter, a method for manufacturing a separator according to a first embodiment will be described with reference to fig. 7 and 8.
As shown in fig. 7, the separator 10 is sandwiched between the outer cloth 21 and the inner cloth 22, the outer peripheries of the outer cloth 21 and the inner cloth 22 are thermally welded in a stacked state, and the outer peripheries of the outer cloth 21 and the inner cloth 22 are sewn by the end members 23. The outer periphery of the cover 20 is formed with a sewing trace S. Accordingly, the vicinity of the edge 14 of the first end piece 11 and the second end piece 12 in the width direction D and the vicinity of the edge of the second end piece 12 in the winding direction P are also sewn by the outer cloth 21 and the inner cloth 22.
Next, as shown in fig. 8, the airbag 40 is inserted from the opening 24 formed at the portion where the first lining 22a and the second lining 22b overlap, and is accommodated between the first lining 22a and the partition panel 10. Further, the core material 30 elastically deformed into a substantially flat state by the bent shape is inserted from the opening 24 between the first and second back cloths 22a and 22b and accommodated between the first outer cloth 21a and the separator 10 to produce the arm band 1. In addition, after the airbag 40 and the core material 30 are received in the cover 20, the first and second cloths 22a and 22b may be sewn together to close the opening 24.
[ Effect of arm Belt ]
Fig. 9 is a diagram for explaining the operation of the arm band according to the first embodiment, and is a diagram showing the arm band without the airbag. Fig. 10 is a diagram illustrating the operation of the arm band of the first embodiment. Fig. 11 is a diagram illustrating the operation of the arm band of the comparative example, and is an arm band diagram showing the airbag omitted. Fig. 12 is a diagram illustrating an operation of the arm band of the comparative example. The operation of the arm band according to the first embodiment will be described below with reference to fig. 9 to 12.
The sphygmomanometer cuff (arm band 1) of the first embodiment includes: a band-shaped cover part 20, which is wound on the object (arm M) and has a winding direction P longer than a width direction D; a core material 30 which is accommodated in the hood 20, has elasticity, and is bent in a winding direction P; a fluid bag (air bag 40) which is accommodated in the cover portion 20, is arranged on the inner peripheral side of the core material 30, is inflated by the supply of the fluid, and is deflated by the discharge of the fluid; and a separator 10 that is joined to the cover 20 while separating the core member 30 and the fluid bag (air bag 40), wherein the separator 10 includes a slit 15 (fig. 6) at an edge 14 in the width direction D.
Accordingly, as shown in fig. 9, the separator sheet 10 is formed with the pleats 10A, and the pleats 10A are formed only in the central portion in the width direction D of the substantially central portion in the winding direction P. Therefore, as shown in fig. 10, in the airbag 40, a bulge portion 40A that is raised by the fold 10A of the separator 10 is formed in the central portion in the width direction D. On the other hand, the end portion of the airbag 40 in the width direction D is not formed with the bulge portion 40A.
Therefore, it can be designed that, in the airbag 40, the fold formed at the edge 41 in the width direction D by pressing (crushing) the tubular body is not stacked with the bulging portion 40A formed at the central portion in the width direction D. As a result, it is possible to prevent a large load from being applied to the edge 41 of the airbag 40 and to prevent a hole from being formed in the edge 41 of the airbag 40.
On the other hand, as shown in fig. 11, since the partition panel 910 arranged on the inner peripheral side without the slit 15 and the outer cloth 21 arranged on the outer side are joined over the entire periphery thereof, the partition panel 910 arranged on the inner peripheral side generates a surplus portion due to the difference in the circumferential length between the outer periphery and the inner periphery in the state of being rolled. Due to this surplus portion, in the separator 910, a wrinkle 910B that protrudes toward the inner peripheral side is generated over the entire region in the width direction D.
Further, the airbag 40 is also formed with the fold 40B over the entire region in the width direction D due to the pressing of the fold 910B of the divided sheet 910. Therefore, the airbag 40 is formed with: a fold formed at the edge 41 in the width direction D over the entire area in the winding direction P; and a fold 40B formed over the entire area in the width direction D.
Further, the airbag 40 repeatedly contracts and expands, thereby repeatedly bending the portion where the two folds overlap and applying a large load. Further, since the portion where the core member 30 is disposed is kept in a state of being curled even if the arm band 1 is not attached to the arm, the airbag 40 is folded at the edge 41 in the width direction D even in a storage state. Therefore, a hole may be formed at a portion of the airbag 40 where the two creases overlap.
In the sphygmomanometer cuff (arm band 1) according to the first embodiment, the edge of the core member 30 is received by the spacer 10 joined to the cover portion 20 at the end in the wrapping direction P, and therefore the cover portion 20 can be prevented from being deformed.
Further, since the separator 10 is provided with only the slits 15 in a simple structure, productivity is good.
In the sphygmomanometer cuff (arm band 1) of the first embodiment, the cuts 15 are provided on both sides in the width direction D in the separator 10 (fig. 6).
Accordingly, in the airbag 40, the folds formed at the edges 41 on both sides in the width direction D formed by pressing the tubular body can be prevented from being stacked on the raised portion 40A formed at the central portion in the width direction D. As a result, it is possible to prevent a large load from being applied to the edge 41 of the airbag 40 and to prevent holes from being formed in the edges 41 on both sides of the airbag 40 in the width direction D.
In the sphygmomanometer cuff (arm band 1) according to the first embodiment, the cover portion 20 includes the opening 24 (fig. 8) for inserting and accommodating the core material 30 and the fluid bag (air bag 40).
Accordingly, after the cover 20 and the spacer 10 are sewn together, the core 30 and the fluid bag (the airbag 40) can be inserted through the opening 24 and accommodated in the cover 20. Therefore, the sphygmomanometer cuff can be produced in a few steps. As a result, the production efficiency of the sphygmomanometer cuff can be improved.
In the sphygmomanometer cuff (arm band 1) of the first embodiment, the separator 10 is constituted by the end pieces (first end piece 11, second end piece 12) and the narrow-width portion 13, and includes R-shaped portions 11b, 12b (fig. 6) smoothly connecting the narrow-width portion 13 and the end pieces (first end piece 11, second end piece 12), the end pieces (first end piece 11, second end piece 12) being provided at the ends in the winding direction P by the slits 15, and the narrow-width portion 13 extending from the base ends 11c, 12c of the end pieces (first end piece 11, second end piece 12) in the winding direction P and having a width narrower than the width of the end pieces (first end piece 11, second end piece 12).
Accordingly, the end pieces (the first end piece 11, the second end piece 12) and the narrow-width portion 13 can be connected in a smooth shape. Therefore, when the core material 30 elongated from the substantially cylindrical shape is inserted and accommodated into the hood 20 from the opening 24, the tip end of the core material 30 pressing the surface of the spacer 10 by the restoring force can be prevented from being caught by the connecting portion of the narrow portion 13 and the end pieces (the first end piece 11, the second end piece 12). As a result, the insertion of the core material 30 into the cover 20 can be improved, and the production efficiency can be improved.
Further, the narrow-width portion 13 can take over the insertion of the core material 30 as a guide when the core material 30 is inserted into and accommodated in the hood portion 20. Therefore, the core material 30 can be accommodated at a predetermined position. Specifically, in fig. 8, the separator 10 inserted from the opening 24 in the direction of the arrow can be easily inserted. Further, the strength of the separator 10 can be improved.
In the sphygmomanometer cuff (arm band 1) of the first embodiment, the side edges 11a, 12a where the end pieces (first end piece 11, second end piece 12) are connected to the narrow-width portion 13 are inclined, and form an obtuse angle with the narrow-width portion 13 (fig. 6).
Accordingly, when the core material 30 is inserted into and accommodated in the hood portion 20, the tip end of the core material 30 can be brought into contact with and slid on the inclined side edges 11a, 12a of the connecting narrow-width portion 13 of the end pieces (the first end piece 11, the second end piece 12). Therefore, when the core material 30 is inserted into and accommodated in the hood 20, the leading end of the core material 30 can be prevented from being caught by the side of the connecting narrow-width portion 13 of the end piece (the first end piece 11, the second end piece 12). As a result, the insertion of the core material 30 into the cover 20 can be improved, and the production efficiency can be improved.
Above, the sphygmomanometer cuff of the present invention is described based on the first embodiment. However, the specific constitution is not limited to the present embodiment, and design changes and additions are allowed without departing from the scope of the gist of the invention claimed in each of claims.
In the first embodiment, an example is shown in which the peripheral edges are sewn in a state where the separator 10 is sandwiched and stacked between the outer cloth 21 and the inner cloth 22. However, the present invention is not limited to this embodiment, and for example, the separator sewn to the inner cloth may be sewn to the outer cloth.
In the first embodiment, an example is shown in which the airbag 40 is constituted by a two-layer structure in which two bag bodies are superimposed. However, the airbag may be a single bag body, or may have a multilayer structure in which three or more bag bodies are stacked.
In the first embodiment, an example is shown in which the separator 10 is provided with the cut 15. However, as shown in fig. 13, a weak portion 52 that is softer than the general portion 51 may be provided in the portion of the notch 15. Accordingly, in the separator 10, the pleats 10A are formed only in the central portion in the width direction D in the substantially central portion in the winding direction P, or the strength of the pleats 10A formed in the end portions in the width direction D of the separator 10 can be reduced to such an extent that no hole is formed in the airbag 40. For example, the fragile portion 52 may be a structure in which a plurality of slits are formed in the vicinity of the center in the winding direction P among the edges in the width direction D from a rectangular sheet.
Further, the fragile portion may be a structure in a state where a connecting portion having a width thinner than the narrow-width portion 13 is left, which connects the edge 14 of the first end member 11 and the edge 14 on the second end member 12 side in the winding direction P. Further, the fragile portion may be configured to leave one or more intermediate connecting portions connecting the side 11a and the side 12a in the winding direction P between the connecting portion and the narrow-width portion 13. In other words, the separator 10 can be formed with an opening as a weak portion.
In the first embodiment, an example is shown in which a slit 15 is formed from a rectangular sheet in the width direction D in the edge 14 in the vicinity of the center in the slitting winding direction P. However, the separator 10 may be formed by forming portions corresponding to the first end member 11, the narrow-width portion 13, and the second end member 12 from rectangular sheets, respectively, and by ultrasonic welding or sewing. Accordingly, the slit 15 is formed in the separator 10.
In this case, the ultrasonically welded or stitched portion is a portion in which the vicinity of the base end 11c of the first end piece 11 and the vicinity of the end portion of the narrow-width portion 13 on the first end piece 11 side are stacked in the thickness direction. Further, the ultrasonically welded or sewn portion is a portion in which the vicinity of the base end 12c of the second end piece 12 and the vicinity of the end portion of the narrow-width portion 13 on the second end piece 12 side are stacked in the thickness direction.
In this case, it is preferable that the first end piece 11 is stacked on the surface of the separator sheet 10 facing the core material 30 so as to be positioned closer to the core material 30 than the narrow-width portion 13. Further, on the surface of the separator sheet 10 facing the core material 30, the narrow-width portions 13 are stacked so as to be positioned closer to the core material 30 than the second end piece 12.
Accordingly, when the core material 30 is inserted into the opening 24, the segment formed on the portion where the first end piece 11 and the narrow-width portion 13 are stacked can be prevented from being caught by the segment formed on the portion where the second end piece 12 and the narrow-width portion 13 are stacked.
Further, the partition sheet 10 may be formed from a rectangular sheet longer than the partition sheet 10 by using a die (die), the length in the width direction D and the winding direction P. Also in this case, a slit 15 is formed in the separator 10.
In the first embodiment, an example is shown in which the slits 15 are provided at both edges 14 in the width direction D of the separator 10. However, the slit 15 may be provided on any one of the edges of the separator 10 in the width direction D. For example, when the hole is provided only at one edge in the width direction D of the airbag 40, the notch 15 may be provided only at one edge. This is the same as the case where the notch 15 is a fragile portion.
In the first embodiment, an example is shown in which the opening 24 is formed at a portion where the first and second cloths 22a and 22b overlap. However, the opening may be provided at the end (end) opposite to the opening 24 in the winding direction P of the first back fabric 22 a.
In the first embodiment, an example is shown in which the core material 30 is made of polypropylene (PP). However, the core material may be made of, for example, metal or the like, as long as it has elasticity and is capable of returning to an original substantially cylindrical shape when the load is removed even if the substantially cylindrical shape is opened in a flat plate shape by applying the load.
In the first embodiment, the air bag 40 is shown as an example of the fluid bag. However, the fluid bag is not limited to this, and may have a structure in which liquid flows into the fluid bag.
In the first embodiment, an example in which the present invention is applied to a sphygmomanometer worn on an arm as a test subject is shown. However, the present invention can also be applied to a blood pressure monitor worn on the wrist as a subject.
