Description

  The present invention relates to a wrist band of a blood pressure monitor, a wearing part, and a blood pressure monitor.

  A typical sphygmomanometer is an arm band (also called a cuff) with a built-in air bag, a pressure sensor communicating with the air bag through an air tube, a pressurizing pump and an exhaust valve, a control unit for calculating a blood pressure value, and an operation It consists of a switch and a display unit. In an oscillometric sphygmomanometer, for example, an arm band is wound around the user's upper arm, air is sent into the arm band to increase the tightening pressure of the arm, and pressurize until the pulse wave from the artery disappears. Then, the blood pressure value is calculated from the wave height state between the appearance and disappearance of the pulse wave when the pressure is reduced at a constant flow rate.

  As an arm band used for such a blood pressure monitor, a substantially rectangular band having an air bag sandwiched between an outer cloth and an inner cloth, an annular clasp attached to one end in the longitudinal direction of the band, and a clasp One having a hook-and-loop fastener that fixes the other end of the band-like body inserted and folded back is known (for example, see Patent Documents 1 and 2).

  FIG. 9 is a perspective view showing a state when the conventional armband 100 is wound around the arm. The armband 100 fixes a belt-like body 101 containing an air bag (not shown), an annular fastener 102 attached to one end in the longitudinal direction of the belt-like body 101, and the other end of the belt-like body 101. And a surface fastener 103. In order to wind the arm band 100 around the arm, as shown in FIG. 9, first, the other end portion of the band-like body 101 is inserted into the fastener 102 to form an annular shape, and is passed through the arm in the direction of arrow a.

FIG. 5 is a perspective view of a mounting component 20 that is mounted on an armband 100 that does not have a protrusion 14. It is a perspective view which shows the state when the conventional arm band 100 is wound around an arm. It is a figure for demonstrating the cause which looseness occurs in the arm band.

  Hereinafter, an arm band, a wearing part, and a sphygmomanometer will be described with reference to the drawings. It should be understood, however, that the present invention is not limited to the drawings or the embodiments described below.

  1A and 1B are a development view and a side view of the armband 10, respectively. The arm band 10 is an arm band (cuff) for a sphygmomanometer, and is wound around the upper arm of the user, for example, when measuring blood pressure. The armband 10 includes a belt-like body 11, a fastener 12, a hook-and-loop fastener 13, a protrusion 14, an air bag 15, and a connecting portion 16.

  The belt-like body 11 is a substantially rectangular member with a built-in air bag 15. The belt-like body 11 is made, for example, by sandwiching the air bag 15 between two resinous cloths and stitching the peripheral edges of the cloths. The air bag 15 is disposed in a region on the one end E1 side from the approximate center in the longitudinal direction (arrow L direction) of the belt-like body 11. Moreover, the connection part 16 connected with the air tube of a sphygmomanometer is formed in the surface of the front side of the air bag 15, and the connection part 16 penetrates the surface of the strip | belt-shaped body 11, and is exposed outside. .

  The fastener 12 is an annular body made of round steel, and is attached to the end portion E1 side in the longitudinal direction of the strip 11 in parallel with the one end portion E1. One end E1 of the strip 11 and the fastener 12 are inclined at an angle of about 80 degrees with respect to the long side of the strip 11 so as to be easily wrapped around the upper arm. The other end E2 in the longitudinal direction of the belt-like body 11 is inserted into the fastener 12.

  The fasteners 12 are fixed to the band-like body 11 by stitching or the like so as not to move in the longitudinal direction, for example, in a state where a half thereof is sandwiched between resin cloths constituting the band-like body 11. However, the fastener 12 can be rotated in the direction of arrow C with the side fixed to the belt 11 as an axis, and the angle with respect to the surface of the belt 11 can be changed. For this reason, when the other end E2 of the inserted band-like body 11 is pulled, the fastener 12 falls in the pulling direction according to the movement, and changes the angle with respect to the surface of the band-like body 11.

  The hook-and-loop fastener 13 is inserted into the fastener 12 and fixes the other end portion E2 of the belt-like body 11 that is folded back with the fastener 12 interposed therebetween. The hook-and-loop fastener 13 includes a hook surface 131 stitched to the surface on the other end E2 side of the strip 11 and a loop surface 132 stitched to the surface of the strip 11 from the vicinity of the hook surface 131 to the vicinity of the one end E1. Have. The hook-and-loop fastener 13 allows the armband 10 to be easily attached and detached with one hand.

  The protrusion 14 is an elongated protrusion provided in the width direction (arrow W direction) of the belt-like body 11 along the fastener 12 on one end E1 side in the longitudinal direction of the belt-like body 11. The protrusion 14 is disposed between the one end E1 and the fastener 12 at a position where the protrusion 12 contacts the fastener 12 when the fastener 12 is tilted toward the protrusion 14. The protrusion 14 is formed, for example, by sandwiching a resin or metal cylindrical member with a resin cloth constituting the belt-like body 11.

  FIGS. 2A to 2E are views for explaining the operation of the fastener 12 and the protrusion 14 when the arm band 10 is attached to the arm.

  FIG. 2A is a side view of the arm band 10 wound with the other end E2 of the band-like body 11 inserted into the fastener 12 and wound. FIG. 2B is an enlarged view of the vicinity of the fastener 12 shown in FIG. As shown in FIGS. 2 (A) and 2 (B), when the strip 11 is inserted into the fastener 12 and pulled in the direction of arrow A, the fastener 12 rotates in the direction of arrow C2 accordingly, It falls to the opposite side to the protrusion 14.

  FIG. 2C shows the arm band 10 when the other end E2 of the band-like body 11 is pulled in the direction of arrow B opposite to the direction of arrow A from the state of FIG. Moreover, FIG.2 (D) and FIG.2 (E) are the enlarged views of the fastener 12 vicinity shown in FIG.2 (C). As shown in FIGS. 2 (C) and 2 (D), when the strip 11 is pulled in the direction of arrow B, the fastener 12 rotates in the direction of arrow C1 opposite to the direction of arrow C2 accordingly. It falls down toward the portion 14 and comes into contact with the protruding portion 14 with the strip 11 interposed therebetween.

  By pulling the other end E2 of the band 11 in the direction of arrow B, the ring of the arm band 10 shown in FIG. 2C is narrowed, and the arm band 10 is attached to the arm. Since the arm band 10 is provided with the protrusions 14, unlike the case of the arm band 100 shown in FIG. 10, there is no gap between the clasp 12 and the band-shaped body 11 at this time. Further, since the fastener 12 and the protrusion 14 are in contact with each other with the belt-like body 11 interposed therebetween, the belt-like body 11 is held at the contact point P shown in FIG. For this reason, even if the user releases his / her hand from the armband 10 on the way, the movement of the band-like body 11 in the direction of arrow D in which the ring of the armband 10 loosens is prevented. Therefore, it is possible to attach the arm band 10 without loosening even when the hand is released by the fasteners 12 and the protrusions 14 at the time of attachment. As described above, when the arm band 10 is attached, the fastener 12 and the protruding portion 14 are clamped with the band-like body 11 interposed therebetween, and act as a stopper that prevents the arm band 10 from loosening.

  FIGS. 3A to 3C are views for explaining the operation of the fastener 12 and the protrusion 14 when the armband 10 is removed from the arm.

  FIG. 3A shows the arm band 10 viewed from the side when the other end E2 of the band-like body 11 is moved in the direction of the arrow F from the state shown in FIG. The figure is shown. FIG. 3B is an enlarged view of the vicinity of the fastener 12 shown in FIG. As shown in FIGS. 3 (A) and 3 (B), when the other end E2 of the strip 11 is pulled in the direction of arrow F, the fastener 12 rotates again in the direction of arrow C2 accordingly, and the projection The part 14 is lifted up.

  By moving the fastener 12 in this manner, a gap S is generated between the fastener 12 and the strip 11 as shown in FIG. 3B, and the strip 11 is released. For this reason, as shown in FIG.3 (C), the part of the strip | belt-shaped body 11 inserted in the fastener 12 can be easily moved to the arrow G direction, and the ring of the arm band 10 can be loosened. That is, at the time of detachment, the armband 10 can be removed in the same manner as the armband 100 of FIG. Thus, when the armband 10 is removed, the fasteners 12 and the protrusions 14 do not act as a stopper that prevents the armband 10 from loosening.

  4A to 4C are diagrams illustrating examples of a preferable positional relationship between the fastener 12 and the protrusion 14. In these drawings, a longitudinal section of the armband 10 in the vicinity of the fastener 12 is shown.

  The height and position of the protrusion 14 are set according to the size of the hole of the fastener 12. In that case, it is preferable to set the height and position of the protrusion 14 so that the contact point P between the fastener 12 and the protrusion 14 is higher than the upper end of the convex portion 111 of the strip 11. The convex portion 111 refers to a protruding portion of the band-shaped body 11 at a position where the fastener 12 is attached to the band-shaped body 11.

  In other words, when the fastener 12 is tilted toward the protrusion 14, the fastener 12 comes into contact with the protrusion 14 at a height equal to or higher than the upper end of the convex portion 111 (is placed on the protrusion 14). It is preferable to set the position of the protrusion 14 in the longitudinal direction of the body 11. In particular, as shown in FIG. 4A, when the fastener 12 is tilted toward the protrusion 14, the upper end of the protrusion 14 and the lower end of the fastener 12 on the side not fixed to the strip 11 Most preferred is a position where they contact each other. If the contact point P is higher than the upper end of the convex portion 111, the protrusion 14 may contact the convex portion 111 as shown in FIGS. 4 (A) and 4 (B). As shown in C), there may be a gap between the protrusion 14 and the protrusion 111. In addition, if the contact P is higher than the upper end of the convex portion 111, the contact P may be closer to the one end E1 side than the upper end of the protruding portion 14, as shown in FIG. As shown in FIG. 4 (C), it may be closer to the convex portion 111 than the upper end of the protruding portion 14.

  Further, in order for the contact point P to be higher than the upper end of the convex portion 111, as shown in FIGS. 4A to 4C, the height H1 of the protruding portion 14 from the surface of the belt-like body 11 is obtained. Is preferably not less than the height H2 of the convex portion 111.

  FIG. 5A and FIG. 5B are diagrams illustrating an example of an unfavorable positional relationship between the fastener 12 and the protrusion 14. These figures also show a longitudinal section of the armband 10 in the vicinity of the fastener 12.

  As shown in FIG. 5 (A), if the projection 14 is too close to the projection 111, the projection 14 is caught in the hole of the fastener 12 when the fastener 12 is tilted toward the projection 14. Therefore, the contact point P becomes lower than the upper end of the convex portion 111. In addition, as shown in FIG. 5B, even when the projection 14 is too far from the projection 111, when the fastener 12 is tilted toward the projection 14, the projection 14 is located between the projection 111 and the projection 111. Thus, the fastener 12 is caught, and the contact point P becomes lower than the upper end of the convex portion 111. In either case, the fastener 12 is not easily lifted with respect to the protrusion 14 when the armband 10 is removed, and therefore the band 11 is not released and the band 11 is difficult to move. Therefore, as described above, the position of the protrusion 14 is set so that the fastener 12 contacts the protrusion 14 at a height higher than the upper end of the convex portion 111 when the fastener 12 is tilted toward the protrusion 14. It is preferable to do.

  2 (A) to 5 (B) all show a protrusion 14 having a rounded upper end, but if the height and position satisfy the above conditions, the shape of the protrusion is It is not limited to a round shape.

  6A and 6B are diagrams showing examples of the shape of the protrusions. These figures also show a longitudinal section of the armband 10 in the vicinity of the fastener 12. For example, instead of the protrusion 14, a protrusion 14 having a triangular cross section as shown in FIG. 6A (that is, a triangular prism) may be used, or as shown in FIG. 6B. You may use the protrusion part 14b whose cross section is a rectangle (namely, square pillar).

  Further, in the arm band 10, the protruding portion 14 extends in the entire width direction of the band-shaped body 11, but when the band-shaped body 11 is sandwiched between the fastener 12 and the protruding portion, a load that can prevent the arm band from being loosened. If given to the belt-like body 11, one or a plurality of protrusions may be provided only on a part of the belt-like body 11 in the width direction.

  FIG. 7 is a development view of the armband 10 '. The arm band 10 ′ shown in FIG. 7 is the same as the arm band 10 shown in FIG. 1 (A), but along the fasteners 12 at three positions in the width direction of the band-like body 11, spaced apart from each other. A protrusion 14c is provided. As described above, the protrusions may be provided only on a part of the strip 11 in the width direction.

  As described above, the armband 10 has the fastener 12 and the elongated protrusion 14 on the one end E1 side in the longitudinal direction of the belt-like body 11. When the other end E <b> 2 of the belt-like body 11 is inserted and the belt-like body 11 is folded back with the fastener 12 interposed therebetween, the fastener 12 is tilted toward the protrusion 14, and between the protrusion 14. To hold the strip 11 (that is, load the strip 11). Accordingly, when the user winds and attaches the armband 10 around the arm, it is possible to prevent unintentional loosening of the armband 10. In addition, the fastener 12 is lifted with respect to the protrusion 14 to release the strip 11 when the strip 11 is turned off (that is, the load on the strip 11 is removed). Thereby, when the user removes the armband 10, the ring of the armband 10 can be easily expanded in the same manner as the conventional armband.

  The arm band 10 is not limited to the upper arm type sphygmomanometer and can be applied to any sphygmomanometer including a wrist type.

  FIG. 8 is a perspective view of the mounting component 20 mounted on the armband 100 that does not have the protrusion 14. The arm band 100 includes a belt-like body 101 containing an air bag (not shown) and an annular fastener 102 into which the other end in the longitudinal direction of the belt-like body 101 (not shown) is inserted. Unlike the above, it does not have the protrusion 14. The fastener 102 is provided on one end E1 side in the longitudinal direction of the strip 101 so that the angle with respect to the surface of the strip 101 can be changed.

  The mounting component 20 includes a “U” -shaped concave portion 21 having the same thickness as that of the belt-like body 101 and an elongated protrusion 24 provided on the upper surface. The mounting component 20 is mounted on the arm band 100 by fitting the recess 21 into the one end E1 of the band 101. The projecting portion 24 is disposed at a position where it comes into contact with the clasp 102 when the clasp 102 is tilted toward the one end E1 of the strip-shaped body 101 with the mounting component 20 mounted on the strip-shaped body 101. . If the mounting component 20 having such a protrusion 24 is mounted, the same loosening prevention effect as that of the arm band 10 can be obtained even with the arm band 100 of an existing blood pressure monitor that does not have the protrusion 14.
