Description

The present invention relates to a living body pressing equipment that can greatly improve the mounting of the living body.

In recent years, sphygmomanometers have been widely used not only in hospitals and the like, but also for general households for the purpose of health management. These home blood pressure monitors are usually automatic blood pressure monitors that are easy to operate.
Various types of automatic sphygmomanometers have been developed, one of which is an oscillometric electronic sphygmomanometer. This oscillometric electronic sphygmomanometer detects a pulse wave superimposed on the internal pressure of a fluid bag (usually referred to as an air bag because air is used), and detects blood pressure based on the amplitude change of the pulse wave. Is calculated. This oscillometric electronic sphygmomanometer is a living body compression device (generally also referred to as a cuff) wound around an upper arm and having a fluid bag, and a pressure sensor, a pump, and an exhaust that communicate with the fluid bag via a pipe. It consists of an information processing device connected to a valve, a pressure sensor, a pump and an exhaust valve, an operation switch and a display connected to the information processing device.

(Conventional example)
In addition, biological compression devices having various configurations have been used for the above-described automatic blood pressure monitor.
Next, a conventional living body compression apparatus will be described with reference to the drawings.
FIG. 11 is a schematic reduced view of a living body compression apparatus according to a conventional example, in which (a) shows a front side development view and (b) shows a back side development view.
FIGS. 12A and 12B are schematic views of a living body compression apparatus according to a conventional example, in which FIG. 12A shows a GG arrow view, and FIG. 12B shows an HH arrow view.
11 and 12, the biological compression device 101 includes a fluid bag 2, a belt-like body 130, a fastener 4, a hook-and-loop fastener 133, and the like.

<Fluid bag>
The fluid bag 2 is a substantially trapezoidal bag, and includes an upper surface side sheet, a lower surface side sheet, and a welded portion in which peripheral edges of these sheets are welded. The fluid bag 2 expands and contracts when fluid (usually air) enters and exits. That is, when the living body compression apparatus 101 is wound around the upper arm 10 and air is fed from the joint 21, the fluid bag 2 expands and compresses the upper arm 10.

<Strip-shaped body>
The belt-like body 130 includes a loop sheet 131 and an inner surface cover 135 as outer surface covers, and the fluid bag 2 is accommodated by the loop sheet 131 and the inner surface cover 135 sandwiching the fluid bag 2.
The loop sheet 131 and the inner surface cover 135 are substantially rectangular. The inner surface cover 135 is made of a thin, soft and stretchable cloth (usually a resin cloth) so that it is comfortable to touch when touching the skin. Further, the loop sheet 131 as an outer surface cover is thicker and stronger than the inner surface cover 135 and does not have elasticity.

The periphery of the loop sheet 131 and the inner surface cover 135 is stitched with a thread 113 via a bias tape 134 with the fluid bag 2 or the like sandwiched therebetween. Further, the thread 12 is stitched along the arm axis direction at a substantially central portion in the longitudinal direction. Further, the loop sheet 131 and the inner surface cover 135 have a width dimension on the other end side of the yarn 12 shorter than a width dimension on the one end side so as to easily correspond to the shape of the upper arm 10.
Moreover, the strip | belt shaped object 130 has the skin scissors prevention tag part 150 mentioned later in one edge part.

<Fastener>
The fastener 4 is a round steel formed in a substantially oval shape, and has a hooking portion 41 and a held portion 42. The fastener 4 is attached obliquely at an angle of about 80 ° from the lower side (shoulder side) of the belt-like body 130 in the vicinity of one end in the longitudinal direction of the belt-like body 130. Thereby, the living body compression apparatus 101 can be wound in a state in which the muscular upper arm 10 is substantially in close contact.

  Further, as shown in FIG. 12A, the fastener 4 has one end portion of the folded strip 130 (the bias tape 134 interposed between the hook 41 and the held portion 42 of the fastener 4. The loop sheet 131 and the end portion of the inner surface cover 135, which are stitched by the thread 113, are passed through, and the overlapping strips 130 are stitched by the thread 117 so as to sandwich the held portion 42. That is, the fastener 4 is attached so that the pair of belt-like bodies 130 sandwiching the held portion 42 functions as a holding member and can be rotated. Further, when the hanging portion 41 is rotated to the one end portion side, the hanging portion 41 comes into contact with the upper end of the distal end side portion 153 before becoming horizontal (inclined by about 20 °).

<Skin scissor prevention tag part>
Skin scissor prevention tag portion 150 is formed in the vicinity of one end of strip 130. That is, as shown in FIG. 12A, one end of the belt-like body 130 (the end of the loop sheet 131 and the inner surface cover 135 stitched by the thread 113 via the bias tape 134) is folded back and fastened. It passes between the hanging portion 41 of the metal fitting 4 and the held portion 42. This folding is performed in a state where the belt-like body 130 having a predetermined length is positioned on one end side of the held portion 42 and on the other end side of the held portion 42. The band-like bodies 130 overlapped by folding are stitched by the thread 118 in the vicinity of the folding position, stitched by the thread 117 at the two positions sandwiching the held portion 42, and the thread near the position of the folded tip part. Sutured by 116.

  By doing in this way, the skin scission prevention tag part 150 which consists of the center side part 151, the intermediate part 152, and the front end side part 153 is formed. The center side portion 151 is substantially located between the thread 117 and the thread 116 on the center side of the held portion 42 and is composed of a pair of belt-like bodies 130 that are overlapped with each other. The intermediate portion 152 includes a pair of belt-like bodies 130 that are positioned between a pair of opposing threads 117 and hold the held portion 42 in a freely rotatable manner. Further, the tip end portion 153 is formed of a pair of belt-like bodies 130 that are positioned on one end side of the thread 117 on one end side and are overlapped.

  Here, the skin scissor prevention tag portion 150 including the two strips 130 stitched has a sufficiently large bending rigidity (strength against bending) as compared with the single strip 130. Thereby, when the living body compression apparatus 101 is wound around the upper arm 10, the distal end side portion 153 enters between the skin and the inner surface cover 135, and a space in which the skin is sandwiched (for example, the hanging portion 41 and the held portion 42). Guards against entering the space between. Further, the intermediate portion 152 holds the held portion 42 and can maintain a state in which the front end side portion 153 can be guarded (for example, it is not bent from the vicinity of the thread 117 on one end side). A), the front end portion 153 is supported. Furthermore, the center side part 151 supports the intermediate part 152 so that the intermediate part 152 is not bent from the vicinity of the thread 117 on the other end side, for example.

<Hook fastener>
The biological compression device 101 includes a hook-and-loop fastener 133 as a fixing means that fixes the other end of the belt-like body 130 that is inserted into the fastener 4 and folded back through the fastener 4.
The hook-and-loop fastener 133 is composed of the loop sheet 131 and the hook sheet 32 described above. The hook sheet 32 has a substantially square shape, and is sewn with a thread 15 on the other end side of the loop sheet 131 as an outer surface cover.

<Explanatory film>
The explanatory film 138 has a substantially square shape made of resin, and is printed with points to be noted when the biological compression device 101 is wound around the upper arm 10. The explanatory film 138 has a peripheral edge welded to the other end side of the inner surface cover 135 by a welded portion 139. The explanatory film 138 has a shape smaller than that of the hook sheet 32, and the welded portion 139 is located inside the yarn 15.

<Prevention member>
The removal prevention member 36 is a resin tube and is provided on the other end side of the hook sheet 32. That is, the slip-off preventing member 36 is positioned between the loop sheet 131 and the inner surface cover 135 in the state along the arm axis direction, and is positioned by a pair of opposing threads 14 positioned on both sides in the longitudinal direction. The slip-off preventing member 36 can pass between the hanging portion 41 and the held portion 42 by elastic deformation, and the slip-off preventing member 36 that has passed through functions as a stopper. As a result, when the diameter of the living body compression apparatus 101 is increased, the other end portion of the band-shaped body 130 does not come out of the fastener 4, so that the handleability of the living body compression apparatus 101 can be improved.

  The living body compression device 101 described above is wound in a state of being fitted to the muscular upper arm 10, and the skin is not pinched by the skin scissor prevention tag portion 150. The handleability can be improved.

Various techniques have been disclosed in connection with the present invention.
For example, Patent Document 1 discloses a technique of a wrist band for a sphygmomanometer in which a plurality of bands for fastening a bag body containing an air bag to the upper arm are provided in parallel to the longitudinal direction of the bag body. Bands of this document (bands 5a and 5b shown in FIG. 4) are passed through rectangular irons (12a and 12b) as fasteners, and at the center side of the rectangular iron, the tip part and this A portion corresponding to the tip is attached to the bag.

  Further, Patent Document 2 discloses a blood pressure measurement arm band in which an insertion ring (fastener) for inserting the other end portion of the arm band is attached to an arm band having an air bag inside at a predetermined distance inside from one end portion. The technology is disclosed. In the insertion ring (insertion ring 12 shown in FIG. 3) of this document, one rod portion (hanging portion) is located on the outer surface of the armband, and the other rod portion (held portion) is the armband. Installed inside.

Japanese Utility Model Publication No. 53-593 Japanese Utility Model Publication No. 57-123107

However, when the armband for blood pressure measurement of Patent Document 2 and the above-described biological compression device 101 are wound around the upper arm 10, as shown in FIG. 13, when the other end of the belt-like body 130 is pulled in the pulling direction, The skin scissor prevention tag portion 150 having a high bending rigidity behaves almost like a rigid flat plate.
That is, in the living body compression apparatus 101, the rotation angle β ° of the fastener 4 with respect to the distal end side portion 153 is decreased, and thereby the distal end of the distal end side portion 153 is pressed against the belt-like body 130. At this time, a frictional force is generated between the distal end side portion 153 and the belt-like body 130 in accordance with the pressed force, and thus the user has to pull with a force exceeding the frictional force.

  In addition, when the tip of the distal end portion 153 is pressed against the belt-like body 130, the portion of the belt-like body 130 that comes into contact with the distal end side portion 153 is bent into a shape that warps almost upward, and the belt-like body hung on the hanging portion 41. The portion 130 is bent into a shape that warps substantially downward. Therefore, the user who pulls the other end portion of the belt-shaped body 130 has to forcefully pull it against the state in which the distal end side portion 153 is stretched. In particular, the portion of the belt-like body 130 where the explanatory film 138 and the hook sheet 32 are located has high bending rigidity, and therefore requires several times as much force as the portion without them.

Further, when the explanatory film 138 is hooked on the distal end side portion 153 or the hook sheet 32 is hooked on the hook portion 41, when the user pulls the other end portion of the belt-like body 130, the biological compression device 101 is moved to the upper arm 10. There was a case where I was idle.
The living body compression device 101 needs to be wound around the upper arm 10 with the palm facing upward so that the joint 21 is positioned directly above. was there.
In addition, the idling may occur when pulling with a force exceeding the frictional force described above, or when forcibly pulling against the stretched state.

  By the way, the user performs winding work in various procedures. For example, at the beginning of pulling, pulling leftward, pulling from the state where the central portion of the hook sheet 32 is hung on the hanging portion 41, or aligning the position of the joint 21 with the hook sheet 32 passing through the hanging portion 41, In addition, there is a procedure of your own (also called “hanging”), such as pulling. In other words, the operation of winding the living body compression apparatus 101 around the left upper arm 10 with only the right hand is extremely troublesome for a user who cannot skillfully find his / her own procedure, and wearability (for example, pulling force) Reduction, prevention of idling, and a feeling of winding around a smooth feeling without tension or catching have been desired.

  In addition, as described in Patent Document 1, it is conceivable to reduce the frictional force of the winding work by holding the fastener so as not to contact the belt-like body and increasing the distance between the fastener and the belt-like member. . However, when holding the clasp in this way, the rigidity near the attachment position of the clasp of the skin scissor prevention tag is insufficient, and the skin scissor prevention tag bends in the opposite direction when wearing the band state on the arm, There has been a problem that it may not be possible to serve as a skin scissors prevention tag.

The present invention has been proposed to solve the problems possessed by the prior art as described above, and an object thereof is to provide a living body pressing equipment that can greatly improve the mounting of the living body.

In order to achieve the above-described object, a living body compression apparatus according to the present invention is provided with a fluid bag that expands and contracts when a fluid enters and exits, a belt-like body that houses the fluid bag, and one end of the belt-like body. and a fastener inserted through the other end portion of the living body pressing apparatus is wound around a living body, said fastener is a predetermined distance center side Oite the strip into fastener mounting position from one end of the strip It is attached to the band-shaped body so as not to contact the outer surface of the body, and the band-shaped body has a rigidity at the fastener mounting position higher than a rigidity at one end of the band-shaped body, and a center side from the fastener mounting position. The configuration is such that the rigidity of the portion is higher than the rigidity of the fastener mounting position .

The biological compression device of the present invention is provided at a fluid bag that expands and contracts when fluid enters and exits, a belt-like body that houses the fluid bag, and one end portion of the belt-like body, and the other end portion of the belt-like body is inserted. In the biological compression device that is wound around a living body and the fastener is pulled from the outer surface of the strip when the other end of the strip is pulled to attach the biological compression device to the living body. wherein attached to strip away the strip, the rigid portion holding portion for holding the fastener is attached to the strip body, rather high than the stiffness one end, and said fasteners The holding portion to be held is configured so that the rigidity of the center side portion is higher than the rigidity of the portion where the holding portion holding the fastener is attached to the belt-like body than the portion attached to the belt-like body .

According to living body pressing equipment of the present invention, when winding the living body pressing apparatus to the organism, attached (for example, pulling the reduction of forces, prevention of idling, such as sense of winding smooth without tautness and caught feeling) significantly Can be improved.

At this time, the living body compression apparatus 1 is hung on the upper arm 10 so that the joint 21 is positioned directly above the upper arm 10 with the palm facing upward. Subsequently, the user pulls the other end of the strip 3 in the pulling direction with the right hand.

  At this time, when the distal end side portion 53 and the intermediate portion 52 come into contact with the explanatory film 38, the distal end side portion 53 and the intermediate portion 52 gradually curve corresponding to the slightly curved shape of the explanatory film 38. That is, the distal end side portion 53 and the intermediate portion 52 are not strongly pressed against the band-like body 3 unlike the distal end side portion 153 described above, and are sequentially curved from the distal end side portion 53 having low bending rigidity. Accordingly, the frictional force generated between the film 38 and the explanatory film 38 can be greatly reduced (to a fraction of the frictional force in the living body compression apparatus 101), so that the force for pulling the other end of the belt-like body 3 can be reduced. Can be greatly reduced.

  Further, when the distal end portion 53 and the intermediate portion 52 come into contact with the explanatory film 38, the distal end side portion 53 and the intermediate portion 52 gradually curve corresponding to the explanatory film 38.

That is, the skin scissor prevention tag portion 5 is about 30% longer than the skin scissor prevention tag portion 150. As a result, it is possible to avoid such a problem that the leading end portion of the leading end side portion 53 is caught by a step on the other end side of the explanatory film 38.

  Further, since the skin scissor prevention tag portion 5 has the bending rigidity of the central portion 51> the bending rigidity of the intermediate portion 52> the bending rigidity of the distal end portion 53, the distal end portion 53 that is most easily bent is formed by the intermediate portion 52. The intermediate portion 52 that is supported so as not to be bent and is next easily bent is supported so as not to be bent by the central portion 51. Thereby, the lengthened skin scissor prevention tag part 5 can function as a tag for preventing skin scissors, and can reduce the pulling force as described above.

  Further, as described above, the other end of the hook sheet 32 is housed inside the loop sheet 31. As a result, it is possible to prevent a problem that the end portion of the hook sheet 32 is caught by the hanging portion 41 of the fastener 4 and the living body compression device 1 is idle with respect to the upper arm 10, and the living body compression device 1 is more smoothly moved to the upper arm. 10 can be wound.

4, the other end portion of the band-like body 3 is pulled in the pulling direction in the living body compression device 1, and the intermediate portion 52 is greatly curved as compared with the skin scissor prevention tag portion 5 shown in FIG. The side part 53 is not substantially curved. Here, the reinforcing member 6 corresponding to the intermediate portion 52 is separated from the holding member 43, so that the intermediate portion 52 can be greatly curved.
In this state, the living body compression device 1 can reduce the force of pulling the other end of the strip 3 as described above, and the distal end side portion 53 and the intermediate portion 52 are not bent. The skin scissor prevention tag unit 5 can function as a tag for preventing skin scissors.

  Further, the portion of the strip 3 corresponding to the hook sheet 32 (the hook sheet 32, a part of the loop sheet 31, a part of the inner surface cover 35 and the explanatory film 38) has a larger bending rigidity than the other parts. Have. Therefore, although not shown, the portion of the belt-like body 3 corresponding to the hook sheet 32 is previously curved downward (for example, the radius of curvature is approximately the same as the maximum radius of the upper arm 10). Also good. If it does in this way, the strip | belt-shaped body 3 hung on the hanging part 41 can be pulled easily.

FIG. 5 shows a schematic diagram for explaining the operation at the end of winding of the living body compression apparatus according to the first embodiment of the present invention.
In FIG. 5, the living body compression apparatus 1 is almost wound around the upper arm 10, and the skin scissor prevention tag unit 5 functions as a tag for preventing skin scissors. Further, the skin scissor prevention tag portion 5 of the present embodiment has an improved fit feeling compared to the above-described distal end side portion 153 because the distal end side portion 53 is composed of the loop sheet 31 and the inner surface cover 35 and the like. Can do.
Subsequently, although not shown, the hook sheet 32 is joined to the loop sheet 31 and the winding operation is completed.

  As described above, according to the living body compression apparatus 1 of the present embodiment, the wearability (for example, reduction of pulling force, prevention of idling, feeling of winding around a smooth feeling without a feeling of tension or catching, etc.) is greatly improved. be able to.
