JP 2007-260293 A

  By the way, the above-described sphygmomanometer wrist band is assumed to be used by an unspecified subject. For example, the wrist or the forearm is casted or hung, or other reasons. It is difficult to pass the cylindrical armband to the upper arm of the subject for subjects who are unable to extend their elbows straight. There is a problem that you can not.

  The present invention has been made in view of the above circumstances, and can be used even in situations where it is difficult to pass from the hand, such as a subject who is cast on the wrist or forearm, or whose elbow cannot be straightened. An object of the present invention is to provide an arm band for a blood pressure monitor.

  An arm band for a blood pressure monitor according to the present invention includes a joined portion provided in a tightening mechanism that rolls a belt-shaped flexible arm band into a cylindrical shape and sends a tightening belt wound around the outer peripheral surface thereof. , By making it detachable with respect to the joint provided on the flexible armband, return the flexible armband rounded into a cylindrical shape to a band shape with both ends open, and wrap it around the arm in this state, By rejoining the joint and the joint in that state, it can be used without passing through the hand even for subjects who have cast their wrists or forearms or who cannot extend their elbows straight. It is a thing.

  That is, the sphygmomanometer arm band according to the present invention is obtained by rounding a belt-shaped flexible arm band into a cylindrical shape, and one end of the flexible arm band around the flexible arm band formed in the cylindrical shape. A fastening belt fixed to the outer peripheral surface of the belt and wound around the outer peripheral surface, and joined to a part of the flexible armband, and the flexible armband is tightened by feeding the tightening belt A tightening mechanism, and a joint portion is provided at a predetermined position in the circumferential direction of the flexible armband, and a joint portion is provided in the tightening mechanism, and the joint portion and the joint portion And are formed so as to be detachable from each other.

  According to the sphygmomanometer belt according to the present invention configured as described above, the tightening belt is fed by the tightening mechanism, but one end of the tightening belt is fixed to the arm band, and the tightening mechanism is the arm band. Therefore, when the tightening belt is sent, one end of the tightening belt approaches the tightening mechanism and the cylindrical circumference becomes shorter, thereby reducing the diameter of the flexible armband. It becomes possible to reduce.

  Here, since the joining portion provided at a predetermined position in the circumferential direction of the flexible arm band and the joined portion of the tightening mechanism are detachable from each other, the joined portion is joined to the joining portion. The above-described belt-like flexible armband can be rolled into a cylindrical shape. On the other hand, when the joined portion is removed from the joined portion and not joined to the joined portion, the flexible armband is Is not maintained in a closed cylindrical shape, and can be returned to a band shape with both ends open before being formed into a cylindrical shape.

  This makes it possible to provide blood pressure measurement even in a situation where it is difficult to pass through the arm from the hand without changing the shape of the tube (for example, when the wrist or forearm is cast or when the elbow cannot be straightened). .

  In the sphygmomanometer wristband according to the present invention, it is preferable that a plurality of the joint portions are provided at different positions in the circumferential direction of the flexible armband.

  According to the sphygmomanometer armband having a preferable configuration as described above, the joint portions provided at different positions in the circumferential direction of the flexible armband and the joined portion of the tightening mechanism are detachable from each other. Yes, since the bonded portion can be bonded to any one of the plurality of bonded portions, the above-described band-like flexibility can be obtained by bonding the bonded portion to any one of the plurality of bonded portions. The armband can be rolled up into a cylindrical shape. On the other hand, when the joined part is removed from the joined part and not joined to any joined part, the flexible armband is a closed cylinder. Since it is not maintained in a shape, it can be returned to a strip shape with both ends open before it is formed into a cylindrical shape.

  In addition, since the joint portions are provided at different positions in the circumferential direction of the flexible armband, depending on the joint portion to which the joint portion is selectively joined, the circumferential direction of the flexible armband is determined. The joining position of the tightening mechanism changes, whereby the distance between the position of the tightening mechanism and the one end to which the tightening belt is fixed changes stepwise.

  That is, the initial diameter of the cylindrical flexible armband changes stepwise in accordance with the joint portion to which the joined portion is selectively joined.

  Therefore, even if the operation amount for the tightening mechanism from the initial diameter is the same, the diameter of the armband after the operation is different.

  Therefore, even if the operation amount for the tightening mechanism from the initial diameter is reduced by selecting the joint part to join the joined parts according to the difference in the arm thickness, the arm thickness can be reduced. Can be appropriately adapted to the differences.

  In other words, it is assumed that the sphygmomanometer arm band is used for an unspecified subject, but since the thickness of the subject's arm varies, the tightening belt feed amount (rack and pinion gear and In the case of a form that is sent by meshing, the rack length) needs to be set relatively long in consideration of the difference in the thickness of the arms.

  On the other hand, the armband after blood pressure measurement is completed can be easily removed by simply pushing the release lever, such as a release lever (holding / releasing mechanism), so that the armband can be easily removed from the arm. If the tightening belt is configured to return to the initial state with a simple operation, if the arm of the subject to be used next is thin, the necessary amount of feed of the tightening belt to adapt to the diameter of the arm is long. Therefore, it is necessary to increase the amount of operation with respect to the tightening mechanism for obtaining a long feed amount, and the user who operates it may feel annoying.

  In particular, in the case of use in the home where the subject using this armband is limited to a specific person, if the amount of operation of the tightening mechanism is large each time it is used, the burden imposed on the user Is big.

  Also, in the medical field, when subjects with thin arms are continuous, the same thing as in the case of use at home can occur.

  However, according to the preferred wristband for a blood pressure monitor of the present invention, the operation amount for tightening can be reduced regardless of the thickness of the arm.

  In the sphygmomanometer wristband according to the present invention, it is preferable that the joint portion and the joined portion are relatively rotatable while being joined to each other.

  According to the sphygmomanometer armband having a preferable configuration as described above, the area of the cross-section at any position along the central axis of the armband is obtained by relatively rotating the joint portion and the joined portion. In addition to the substantially equal cylindrical shape, the cross-sectional area at the position along the central axis is also formed into a truncated cone-shaped cylindrical shape that changes depending on the cutting position, and thus is a test part. Even for a subject whose diameter is different between the shoulder side such as the upper arm part and the forearm part side, the cylindrical form can be made appropriate.

  In addition, as a structure which can be relatively rotated in the state in which the joined portion and the joined portion are joined to each other, a structure (configuration) in which both of the joined states can be rotated in the plane of the flexible arm body. For example, one is a protrusion protruding from the surface of the flexible arm, and the other is loose on this protrusion (the frictional force between them is reduced to such an extent that they can rotate with each other). Various structures (configurations) similar to this can be applied, such as a structure (configuration) including a hooked ring or a semicircular ring-shaped hook portion (meaning looseness).

  In the sphygmomanometer armband according to the present invention, the joint portion is formed of the tubular armature in a state where the diameter of the flexible armband is reduced among the flexible armbands rolled into the tubular shape. Provided in the region of the outer peripheral surface that overlaps the inner peripheral surface side, and the tightening mechanism has the main body of the tightening mechanism disposed on the cylindrical outer peripheral surface side, and the joined portion is the cylindrical inner peripheral surface. It is preferable that a support member having a shape straddling the cylindrical outer peripheral surface side portion of the cylindrical flexible armband disposed on the side is provided.

  According to the sphygmomanometer bracelet having a preferable configuration as described above, the tightening mechanism, which is a part provided for the user's operation, can be disposed on the outside where the operation is easy to perform, and the cylindrical inner circumference The part to be joined can be reliably joined to the joint part arranged on the side, or the joining can be reliably released.

  In the bracelet for a blood pressure monitor according to the present invention, each of the joint portions is formed with a folded portion protruding in a direction from the inner periphery of the cylindrical winding toward the outer periphery along the cylindrical circumferential direction, It is preferable that the to-be-joined part is formed with a hook part that is hooked on the folded part.

  According to the sphygmomanometer armband having a preferable configuration as described above, when the tightening belt is fed in the direction of reducing the armband diameter when the blood pressure is measured, the folded portion and the hooking portion are engaged. When the blood pressure measurement is completed and the tightening belt is sent in the direction of increasing the armband diameter, the folded portion and the hooking portion can be used. Can be easily disengaged, the joint between the joint portion and the joint portion can be easily released, and it is easy to prepare for the next blood pressure measurement operation.

  In the bracelet for a blood pressure monitor according to the present invention, the fastening belt extends in a direction orthogonal to the circumferential direction, the rack along the cylindrical circumferential direction, and is arranged along the circumferential direction. A plurality of protrusions are formed, the surface exposed to the outside is formed smoothly, and the rack is formed on the edge of the fastening belt on the back surface facing the flexible armband, It is preferable that the protrusion is formed on the inner surface in the width direction of the back surface facing the flexible armband so as to extend continuously from the rack.

  According to the sphygmomanometer belt having a preferable configuration as described above, the fastening belt rack and the protrusion are formed so as to be continuous along the width direction of the fastening belt. Thin portions formed between the racks and between the racks are formed in a straight line along the width direction of the tightening belt, and the thin portions are less rigid than the racks and ridges. When it is wound in a direction substantially perpendicular to the width direction, it can be rounded to a small diameter, and the occupied space can be reduced.

  In addition, since the surface exposed to the outside is formed smoothly, it is easy to maintain cleanliness because dirt adhered from the outside does not remain or accumulate on the smooth surface, and the smooth surface can be wiped off. Since it is easy to carry out, even if dirt or the like is attached to the surface, the wiping and cleaning effort can be reduced compared with the case where the surface has irregularities.

  In the sphygmomanometer belt according to the present invention, the engagement is enabled to move between an engagement position engaged with the ridge and a release position away from the ridge, and is biased to the engagement position. It is preferable that an engagement / release mechanism having a portion is provided, and the tightening mechanism has a pinion gear that meshes with the rack.

  According to the sphygmomanometer belt having a preferable configuration as described above, the engaging portion urged to the engaging position (the position engaging with the protrusion) is engaged with the protrusion of the tightening belt. Until the engagement portion is moved to the release position away from the ridge against the urging force, the flexible armband can be held in a reduced diameter, so that when measuring blood pressure, Even if air is supplied to the body and the arm body swells, and a load in the direction in which the diameter expands along the cylindrical circumferential direction, the arm body diameter can be maintained and appropriate blood pressure measurement can be performed. .

  On the other hand, by moving the engaging part to the release position against the inferior force, the cylindrical diameter is expanded by the elastic restoring force of the arm itself, thereby releasing the tightening on the test part such as the arm. In addition, the portion to be examined can be easily detached from the arm body.

  In the sphygmomanometer belt according to the present invention, the engagement / release mechanism is supported by the support member so as to be disposed on the cylindrical outer peripheral surface side together with the tightening mechanism. It may be.

  According to the sphygmomanometer belt band configured in this manner, the engagement / release mechanism and the tightening mechanism can be indirectly integrated through the support member, so that the tightening operation is input. The portion to be operated and the portion to which the operation for releasing the tightening is input can be arranged close to each other, and the operation portion can be concentrated in one place.

  In the sphygmomanometer belt according to the present invention, the engagement / release mechanism may be provided integrally with the tightening mechanism.

  According to the sphygmomanometer brace constructed in this way, the engagement / release mechanism and the tightening mechanism can be directly integrated, and therefore the engagement / release mechanism and the tightening mechanism are directly connected. The number of parts can be reduced.

  According to the sphygmomanometer belt according to the present invention, it is difficult to pass through the arm from the hand while remaining in a cylindrical shape (for example, a state where the wrist or the forearm is cast or the elbow cannot be straightened) However, it can be used for blood pressure measurement.

FIG. 5 is a diagram corresponding to FIG. 5, in which the solid line is the state in which the cylindrical diameter is reduced by operating the dial, and the two-dot chain line is the state in which the cylindrical diameter is increased by operating the release lever (before the diameter is reduced). State).

  Hereinafter, embodiments according to the armband for a blood pressure monitor of the present invention will be described with reference to the drawings.

  1 and 2 are views showing a sphygmomanometer arm band 100 according to an embodiment of the present invention, FIG. 1 is a diagram showing a developed state of a substantially rectangular sphygmomanometer arm band 100, and FIG. It is a figure which shows the state which rounded the sphygmomanometer wristband 100 shown in FIG. 1 in the cylinder shape.

  The illustrated sphygmomanometer arm band 100 is disposed along a flexible arm band (hereinafter simply referred to as an arm band) 10 formed in a substantially rectangular band shape and a longitudinal direction L of the arm band 10. The tightening belt 20, the tightening mechanism 30 that is movable along the longitudinal direction of the tightening belt 20 (matching the longitudinal direction L of the armband 10), and the tightening belt 20 and the tightening mechanism 30. An engagement / release mechanism 40 that switches holding or releasing of the relative positional relationship, and a joint portion 50 that detachably joins the tightening mechanism 30 to the armband 10 are provided.

  Here, the arm band 10 is supplied with air from a thin flat plate 13 formed in a substantially rectangular band shape with a flexible material such as resin as a core material, and an air hose connection portion 19 superimposed on the thin flat plate 13. The air bag 14 that is inflated by being wrapped is wrapped with a woven fabric 15, and as shown in FIG. 2, one end 11 in the longitudinal direction L of the armband 10 is on the inner peripheral side, and the other end The armband 10 is rounded and formed into a cylindrical shape so that the portion 12 is on the outer peripheral side, and the cylindrical diameter D is adjusted by adjusting the length of the overlapping range between the inner periphery and the outer periphery. It is possible to do. That is, the diameter D can be reduced as the length of the overlapping range is increased.

  In addition, since the longitudinal direction L in the unfolded state coincides with the cylindrical circumferential direction, the armband 10 formed in a cylindrical shape will be described below with reference sign L also in the circumferential direction.

  The fastening belt 20 has both ends 21 and 22 in the longitudinal direction fixed to the outer peripheral surface of the armband 10, and an intermediate portion other than the both ends 21 and 22 is not fixed to the outer peripheral surface of the armband 10. It is provided in a floating state.

  Of these two end portions 21 and 22, one end portion 22 is fixed in the vicinity of the end portion 12 of the armband 10, and the other end portion 21 is in the vicinity of the center portion in the longitudinal direction L of the armband 10. It is fixed.

  If only the end portion 21 near the center in the longitudinal direction L of the armband 10 is fixed to the armband 10, the end portion 22 in the vicinity of the end portion 12 of the armband 10 is not necessarily the armband 10. In the case where the end portion 22 is not fixed, the arm band 10 is formed in a cylindrical shape, and the fastening belt 20 is wound around the outer peripheral surface of the arm band 10. In this state, the posture of the fastening belt 20 is not stable, and an excessive load is applied to the end 21 on the fixed side and durability is lowered. Therefore, both ends 21 and 22 are fixed to the armband 10. It is preferable.

  Further, as shown in FIG. 3 (a), the fastening belt 20 has a front (front) surface 20a that is exposed outwardly, and is smoothly formed. As shown in FIG. A rack 23 is formed along the longitudinal direction L at an edge portion along the longitudinal direction L of the fastening belt 20 in the back (back) surface 20b which is a surface facing 10 and a rack 23 is formed among the back surface 20b. A plurality of protrusions 24 extending in a direction substantially perpendicular to the circumferential direction L (width direction W) and arranged along the circumferential direction L are formed on the inner side in the width direction W from the edge portion. .

  Each protrusion 24 extends along the width direction W so as to be continuous with each rack 23.

  As shown in FIG. 4, the tightening mechanism 30 includes a pinion gear 31 that meshes with the rack 23 formed on the edge of the back surface 20 b of the tightening belt 20 from the outside of the edge of the tightening belt 20, and the pinion gear 31. When the pinion gear 31 is rotated counterclockwise in FIG. 4 when the pinion gear 31 is rotated counterclockwise as shown in FIG. When the pinion gear 31 is rotated by rotating the dial knob 32 in the direction R, the tightening mechanism 30 is engaged by the engagement between the rack 23 and the pinion gear 31. The linear displacement is made along the longitudinal direction L of the fastening belt 20 relative to the fastening belt 20, and at the displaced position, the string winding spring 34 is moved. Elastic restoring force acts on that.

  Then, when the fastening mechanism 30 is linearly displaced along the longitudinal direction L of the fastening belt 20 relative to the fastening belt 20, the length of the overlapping range of the inner circumference and the outer circumference of the armband 10. Thus, the cylindrical diameter D of the armband 10 is adjusted.

  The tightening mechanism 30 also includes a base 33 that restricts the movement of the tightening belt 20 in the width direction W through the back surface 20b side of the tightening belt 20 and rotatably supports the pinion gear 31. 33, the armband 10 is provided with a supporting member 60 formed in a substantially rectangular ring shape that can pass through the inner space.

  Here, since the base 33 is passed to the back surface 20b side of the fastening belt 20, and the dial shoot 32 is provided so as to cover the surface 20a of the fastening belt 20 from the outside, the fastening mechanism 30 is provided. Does not come off from the fastening belt 20 in which both end portions 21 and 22 are fixed to the armband 10, and therefore does not fall off from the armband 10.

  The support member 60 holds the base 33 at a portion that passes the surface side that is the outer peripheral surface of the armband 10 that has a cylindrical shape, straddles the armband 10 from the front surface side to the back surface side of the armband 10, Each of the three joint portions 50 (the first joint portion 51, the second joint portion 52, and the third joint portion 53) provided in the arm belt 10 is provided in a portion that passes through the back side that is the inner peripheral surface of the belt 10. A substantially U-shaped joined portion 61 that can be joined to each other is formed.

  The substantially U-shape of the joined portion 61 has a form protruding to the end 12 side of the armband 10. And this fastening part 61 will be in the state joined to arm belt 10 by joining to any one of joined parts 51, 52, and 53 explained in full detail later.

  The engagement / release mechanism 40 includes an engagement position where the ridge 24 formed on the back surface 20b of the fastening belt 20 is engaged from the arm band 10 side, and a release position away from the ridge 24 toward the arm band 10 side. The engaging claw 42 (engaging portion) that is movable between the positions and biased to the engaging position by the elastic force of the string winding spring 43, and the engaging claw 42 against the elastic force of the string winding spring 43 The release lever 41 is displaced to the release position, and the string spring 43 engaging claw 42 and the release lever 41 are attached to the base 33 via a shaft 44 that is pivotally supported by the base 33 of the tightening mechanism 30. The engagement / release mechanism 40 and the tightening mechanism 30 are directly integrated.

  Although not shown in FIG. 4, the right wall surface (the wall surface near the end portion 22) of the ridge 24 is formed in an obliquely inclined surface, while the left wall surface (the end portion 21) of the ridge 24 is formed. The wall on the near side is formed on a surface that rises substantially vertically.

  Since the engaging claw 42 of the engaging / releasing mechanism 40 rotates around the shaft 44 disposed closer to the end 21 than the engaging claw 42, the tightening mechanism 30 is tightened by the tightening belt. 4, the engaging claw 42 rides on the slope that is the right wall surface of the ridge 24, and the reaction force from this slope resists the elastic force of the string spring 43. Thus, the engaging claw 42 acts so as to get over the protrusion 24, and as a result, even if the release lever 41 is not operated, the engaging claw 42 does not hinder the tightening mechanism 30. 20 is linearly displaced to the left in FIG.

  On the other hand, when the tightening mechanism 30 is linearly displaced in the right direction in FIG. 4 with respect to the tightening belt 20, the engaging claw 42 abuts substantially perpendicularly to the left wall surface of the ridge 24, so Unless the engagement claw 42 is moved to the release position, the tightening mechanism 30 is not displaced in the right direction in FIG. 4 with respect to the tightening belt 20.

  Accordingly, the pinion gear 31 and the dial shoot are taken at a position where the dial shoot 32 of the tightening mechanism 30 is rotated and displaced, that is, at a position where the tightening mechanism 30 is linearly displaced in the left direction of FIG. The engagement claw 42 of the engagement / release mechanism 40 and the tightening belt 20 against the elastic restoring force of the chord spring 34 of the tightening mechanism 30 that 32 is trying to return to the position before the dial shooting 32 is rotated. The engagement force acting between the protrusion 24 and the protrusion 24 is balanced, and the tightening mechanism 30 is held at a position linearly displaced in the left direction in FIG. 4 unless the release lever 41 is operated.

  The three joint portions 50 are respectively provided at different circumferential positions on the outer circumferential surface of the armband 10, and the first joint portion 51 of the three joint portions 50 is the one of the three joint portions 50. Of these, the third joint portion 53 is provided at the position closest to the end portion 11 of the armband 10 (the position farthest from the tightening mechanism 30) L1, and the third joint portion 53 is the most from the end portion 11 of the armband 10 among the three joint portions 50. The second joint 52 is provided at a position L2 between the first joint 51 and the third joint 53. The second joint 52 is provided at a far position (position closest to the tightening mechanism 30) L3.

  Further, each of the joint portions 51, 52, and 53 rounds the armband 10 so that one end 11 in the longitudinal direction L of the armband 10 is on the inner peripheral side and the other end 12 is on the outer peripheral side. In the state of being formed into a cylindrical shape (see FIGS. 2 and 5B), the folded portions 51a and 52a projecting in the cylindrical circumferential direction L and extending from the inner periphery of the cylindrical winding toward the outer periphery. 53a is formed, and the joined portion 61 having a substantially U shape of the support member 60 is hooked on each of the folded portions 51a, 52a, 53a, and any of the joined portions 51, 52, 53 is joined. The part 61 is joined, and thereby the arm band 10 and the fastening mechanism 30 are joined.

  The substantially U-shaped joined portion 61 constitutes a hooking portion that is hooked on the folded portions 51a, 52a, and 53a of the joining portions 51, 52, and 53.

  In addition, each of the joined parts 51, 52, 53 and the joined part 61 are detachable, and even after any of the joined parts 51 to 53 and the joined part 61 are once joined, the hook part. The joined portion 61 is moved to the open front end side of the folded portions 51a to 53a of the joined portions 51 to 53 that are hooked, and then displaced outward in the radial direction, so that the joined portion 61 is joined. 51 to 53 can be removed.

  Further, each of the joined portions 51, 52, 53 and the joined portion 61 is either one of the joined portions 51, 52, 53 once the joined portion 61 is joined. The parts 51, 52, 53 and the joined part 61 are relatively rotatable within the surface of the arm body 10.

  And since each joining part 51,52,53 and the to-be-joined part 61 can rotate relatively, when the arm band 10 is mounted | worn with the upper arm which is a to-be-tested part and it clamps, the arm body 10 Can be mounted in a state along the upper arm portion having a truncated cone shape.

  That is, the upper arm portion of the person who is the subject is not a cylindrical shape in which the cross-sectional area at any position along the central axis thereof is substantially equal, such as a brown tube, but from the base portion of the arm located on the shoulder side to the forearm It has a shape like a truncated cone that narrows toward the tip on the part side.

  On the other hand, if it is assumed that the armband 10 is a simple cylinder like the above-described tea cylinder and the diameter expands and contracts, no matter how the feeding amount of the fastening belt 20 is adjusted, The armband 10 is only in contact with a small part of the upper arm portion 10, and even if it is used for blood pressure measurement in this state, the armband 10 can be properly adhered along the shape of the upper arm portion. Therefore, even if air is supplied, the armband 10 can appropriately press the upper arm portion, and the measurement accuracy of blood pressure cannot be increased.

  However, in the sphygmomanometer wristband 100 of the present embodiment, the joint portions 51, 52, and 53 and the joined portion 61 can be relatively rotated in the plane of the arm body 10, so that the arm body 10 is Since it is attached in close contact with the upper arm portion having a truncated cone shape, the arm band 10 supplied with air can press the upper arm portion appropriately, and blood pressure measurement accuracy Can be improved.

  In addition, as a structure which can rotate relatively in the state in which each joined part 51,52,53 and to-be-joined part 61 were mutually joined, the thing of the structure mentioned above (one protruded from the surface of the arm body 10). This is a protrusion, and the other is loosely attached to this protrusion (meaning that the frictional force between them is reduced to such an extent that they can rotate with each other). It is not limited to a structure (configuration) including a hanging portion or the like, and both of the joined states (each joined portion 51, 52, 53, and the joined portion 61) rotate within the plane of the arm body 10. As long as the structure (configuration) is possible, various structures (configurations) similar to those of the configuration of the above-described embodiment can be applied.

  Next, the operation and effects of the sphygmomanometer wristband 100 of this embodiment will be described.

  First, as shown in FIG. 1, the sphygmomanometer armband 100 has the armband 10 in an unfolded state, and the tightening mechanism 30 is connected to one end portion 22 side of the tightening belt 20 (tightening). The elastic restoring force of the string spring 34 of the mechanism 30 is close to the side (the side on which the preload acts)), and in this state, the wound spring 34 is wound around the upper arm portion of the subject.

  Since the armband 10 when the armband is wound around the upper arm portion of the subject is in an unfolded state as shown in FIG. 5A, it is not necessary to reach the upper arm portion from the hand side through the forearm portion. Therefore, the wrist or forearm is fixed with a thick cast, or a drip tube or a string for hanging a cast is attached to the forearm. Even in a situation where it cannot be set, according to the sphygmomanometer armband 100 of the present embodiment, it can be set on the upper arm of the subject.

  When the armband 10 is wound around the upper arm of the subject, the armband 10 is connected to one end 11 of the armband 10 (the end on the side where the joint 50 is provided), as shown in FIG. Tube with a diameter D corresponding to the thickness of the upper arm of the subject so that the portion is positioned on the inner peripheral side with respect to the other end portion 12 (the end portion on the side where the tightening mechanism 30 is provided). Rounded into a shape.

  Then, one of the three joint portions 51, 52, 53 provided in the region of the outer peripheral surface on the other end portion 11 side that overlaps the inner peripheral surface side of the one end portion 12 of the armband 10 is tightened. Of the support member 60 of the mechanism 30, a joined portion 61, which is a substantially U-shaped hook portion disposed on the inner peripheral surface side of the armband 10, is joined, and the armband 10 is formed in a cylindrical shape. The

  Here, the mating joints 51, 52, 53 to which the joined part 61 is joined are one of the three joined parts 51, 52, 53 closest to the joined part 61 opposed thereto, or the joined parts. Of the two joint parts 51 and 52 close to the part 61, the joint part 51 on the side close to the end part 11 or the joint part 52 on the side close to the end part 11 of the two joint parts 52 and 53 close to the joined part 61 Selected.

  Since any one of the joint portions 51, 52, 53 and the joined portion 61 is joined in this way, the diameter of the armband 10 is reduced by operating the tightening mechanism 30. In order to secure a movement allowance for reducing D, when selecting any one of the joint portions 51, 52, 53 to be joined to the joined portion 61, the joint on the side where the diameter D of the armband 10 becomes smaller is selected. Instead of selecting the portion 50, it is necessary to select the joint portion 50 on the side where the diameter D of the armband 10 is increased.

  For example, in FIG. 2, the joint portion 51 closest to the end portion 11 is selected corresponding to the thickest diameter D, and the joined portion 61 is joined to the joint portion 51. In FIG. 5B, corresponding to the intermediate diameter D, a joint 52 provided between the joint 51 closest to the end 11 and the joint 53 farthest from the end 11 is provided. The selected portion 61 is joined to the joined portion 52 by being selected.

  Further, when dealing with the thinnest diameter D, the joint portion 53 farthest from the end portion 11 may be selected, and the joined portion 61 may be joined to the joint portion 53.

  In this way, by joining the joined portion 61 and any one of the joining portions 51, 52, 53, the fastening mechanism 30 is joined to the armband 10, and the armband 10 is formed in a cylindrical shape. Then, the subject himself / herself or an operator such as a nurse turns the dial knob 32 of the tightening mechanism 30 clockwise in FIG. 2 (counterclockwise in FIG. 4) to rotate the coaxial pinion gear 31. When rotated, the rack 23 meshed with the pinion gear 31 is sent relative to the pinion gear 31 in the direction of the arrow La (see FIGS. 2, 4, and 5 (b)). Since 21 is fixed to the armband 10 and the tightening mechanism 30 is joined to the armband 10, when the rack 23 is relatively moved in the direction of the arrow La, as shown by the solid line in FIG. One end of the fastening belt 20 with respect to the attaching mechanism 30 Since 21 approaching, cylindrical circumferential length is shortened (overlapping range between the inner and outer circumferential sides of the cuff 10 is long), thereby, the diameter D of the cuff 10 is reduced.

  Further, since the engagement claw 42 urged to the engagement position (position to engage with the ridge 24) by the urging force of the string winding spring 43 is engaged with the protrusion 24 of the fastening belt 20, the rack 23. Can be held in an arbitrary state in which the diameter D of the armband 10 is reduced by a predetermined amount.

  Then, after the diameter D is reduced to a predetermined amount, air is supplied to the air bag 14 of the armband 10 from the air hose connection portion 19 (see FIG. 1) via an air hose (not shown), whereby the armband 10 is wound. It is possible to press the upper arm of the subject to be used for blood pressure measurement.

  Further, after the blood pressure measurement operation is completed, the air in the air bag 14 is discharged, and then the operator pushes down the release lever 41 against the elastic force of the string spring 43 of the engagement / release mechanism 40. By applying the load, the engaging claw 42 formed integrally with the release lever 41 moves to the release position, and thereby the relative positional relationship between the fastening belt 20 and the fastening mechanism 30 is maintained. Canceled.

  Then, the elastic energy stored in the string spring 34 of the tightening mechanism 30 is released as an elastic restoring force by a predetermined amount of rotation of the pinion gear 31, whereby the pinion gear 31 is in a position before rotating the dial knob 32, That is, as shown by a two-dot chain line in FIG. 6, the tightening mechanism 30 is on the side of one end 22 of the tightening belt 20 (the side on which the elastic restoring force of the string spring 34 of the tightening mechanism 30 is small (the preload acts). (Rack 23 (clamping belt 20) is relatively returned in the direction of the arrow Lb), and the diameter D of the armband 10 is enlarged.

  When the armband 10 can be pulled out in a cylindrical shape from the test portion of the upper arm to the hand, the situation is such that the armband 10 is pulled out from the hand and cannot be pulled out from the hand (for example, wrist or In the case where the forearm is casted or the elbow cannot be straightened), as shown in FIG. 5 (a), the joining of the joined portion 61 and the joined portion 50 is released (the joined portion 61 is removed). The armband 10 is removed from the test portion such as the upper arm portion.

  As described above, according to the sphygmomanometer arm band 100 of the present embodiment, any of the joint portions 51, 52, 53 provided respectively at the predetermined positions (L 1, L 2, L 3) in the circumferential direction L of the arm band 10. The joining portion 61 of the tightening mechanism 30 can be attached to and detached from each other, and the joining portion 61 is joined to one of the joining portions 51, 52, and 53 so that the above-described belt-like armband 10 is formed into a cylindrical shape. On the other hand, when the joined portion 61 is removed from the joined portions 51, 52, 53 and not joined to the joined portions 51, 52, 53, the armband 10 is closed. Since it is not maintained in a cylindrical shape, it can be returned to a band shape in which both end portions 11 and 12 are opened before being formed into a cylindrical shape.

  As a result, it is difficult to pass the sphygmomanometer armband 100 of the first embodiment in a cylindrical shape from the hand to the arm (for example, the wrist or the forearm is cast or the elbow is straightened). In the absence of the blood pressure).

  Further, the sphygmomanometer armband 100 of the present embodiment is provided as the joint portion 50 at three different positions (L1, L2, L3) in the circumferential direction L of the armband 10, and each joint portion 50 is provided. And the joined portion 61 of the tightening mechanism 30 can be attached to and detached from each other, and the joined portion 61 can be joined to any of the joined portions 50. By joining to any one of 50, the above-described belt-like armband 10 can be made into a state of being rounded into a cylindrical shape, while the joined portion 61 is removed from the joined portion 50, When the arm band 10 is not joined to the arm 50, the arm band 10 is not maintained in a closed cylindrical shape, so that it can be returned to a band shape in which both end portions 11 and 12 are opened before being formed into a cylindrical shape. it can.

  And since the junction part 50 is provided in the mutually different position (L1, L2, L3) of the circumferential direction L of the armband 10, according to the junction part 50 to which the to-be-joined part 61 is selectively joined, The joining position of the tightening mechanism 30 in the circumferential direction L of the armband 10 is changed, whereby a distance (in the circumferential direction L) between the position of the tightening mechanism 30 and the one end 21 to which the tightening belt 20 is fixed. (Distance along) changes step by step.

  That is, the initial diameter D of the cylindrical armband 10 changes stepwise in accordance with the joint portion 50 to which the joined portion 61 is selectively joined.

  Therefore, even if the operation amount (the rotation amount of the dial shoot 32) from the initial diameter D to the tightening mechanism 30 is the same, the diameter D of the armband 10 after the operation is different.

  Therefore, the amount of operation with respect to the tightening mechanism 30 from the initial diameter D can be reduced by selecting the joint portion 50 that joins the joint portion 61 according to the difference in the thickness of the arm of the subject. However, it can be appropriately adapted to the difference in arm thickness.

  That is, it is assumed that the sphygmomanometer armband 100 of the present embodiment is used by an unspecified subject, but since the thickness of the arm of the subject varies, the rack of the fastening belt 20 The length 23 (feed amount of the fastening belt 20) needs to be set relatively long in consideration of the difference in the thickness of the arm.

  On the other hand, the armband 10 after the blood pressure measurement is completed is such that the tightening belt 20 returns to the initial state by simply pressing the release lever 41 so that the armband 10 can be easily detached from the arm. Although it is configured, when the arm of the subject to be used next is thin, the necessary feed amount of the tightening belt 20 for adapting to the diameter D of the arm becomes long, and the long feed amount is obtained accordingly. It is also necessary to increase the amount of operation with respect to the tightening mechanism 30, and the user who operates it may feel annoying.

  In particular, in the case of use in the home where the subject using the sphygmomanometer arm band 100 is limited to a specific person, the amount of operation of the tightening mechanism 30 is large each time when used. The burden imposed on the user is large.

  Also, in the medical field, when subjects with thin arms are continuous, the same thing as in the case of use at home can occur.

  However, according to the sphygmomanometer wristband 100 of the present embodiment, the amount of operation for tightening can be reduced regardless of the thickness of the arm.

  In addition, the sphygmomanometer arm band 100 according to the present embodiment has a cylindrical inner peripheral surface side in a state in which the joint portion 50 reduces the diameter D of the arm band 10 among the arm bands 10 rolled into a cylindrical shape. The tightening mechanism 30 arranges the main body of the tightening mechanism 30 (the portion including the pinion gear 31 and the dial knob 32) on the cylindrical outer peripheral surface side. Since the support member 60 having a shape straddling the portion on the cylindrical outer peripheral surface side of the cylindrical armband 10 is disposed on the inner peripheral surface side of the cylindrical portion, the portion provided for the user's operation The dial shoot 32 can be disposed on the outer side where the operation can be easily performed, and the joined portion 61 is securely joined to the joined portion 50 arranged on the cylindrical inner peripheral side or the joining is released. It can be performed.

  In the sphygmomanometer wristband 100 according to the present embodiment, the engagement / release mechanism 40 is supported by the support member 60 so as to be disposed on the cylindrical outer peripheral surface side together with the tightening mechanism 30. The portion where the tightening operation is input (dial knob 32) and the portion where the operation for releasing the tightening is input (release lever 41) can be arranged close to each other, so that the operation portion is concentrated in one place. Structure.

  In the sphygmomanometer bracelet 100 according to the present embodiment, the joints 51, 52, and 53 are folded portions 51 a and 52 a in the circumferential direction L of the cylinder and from the inner periphery to the outer periphery of the cylindrical winding. 53a is formed, and the joined portion 61 is formed with a hook portion (substantially U-shaped portion) that is hooked on each of the folded portions 51a, 52a, 53a. When the fastening belt 20 is fed in the direction of decreasing the diameter D of the belt 10, the folded portions 51a, 52a, 53a and the hooking portion (joined portion 61) are engaged, and the joined portion 50 and the joined portion. 61, while the blood pressure measurement is completed and when the fastening belt 20 is sent in the direction of increasing the armband diameter D, the folded portions 51a, 52a, 53a and the hooking portion Engagement with (joined part 61) is easily released, and joining It can be easily released junction 50 and the bonding portion 61, easily subjected to preparation for the next blood pressure measurement operations.

  In the sphygmomanometer wristband 100 according to the present embodiment, the engagement / release mechanism 40 is provided integrally with the tightening mechanism 30 via the base 33, so The fastening mechanism 30 can be directly integrated to reduce the number of parts.

  In the sphygmomanometer wristband 100 according to the present embodiment, the tightening belt 20 has a smooth surface 20a that is exposed to the outside. Dirt or the like hardly adheres to the surface, and it is easy to maintain a clean state.

  Further, a rack 23 is formed at the edge of the fastening belt 20 in the back surface 20b facing the arm band 10, and the inner side in the width direction W from the edge of the fastening belt 20 in the back surface 20b facing the arm band 10. Since the protrusions 24 are formed in the portion so as to continue to the rack 23, the thin portions 25 (see FIG. 3B) formed between the protrusions 24 of the fastening belt 20 and between the racks 23 are tightened. Since the thin portion 25 is formed in a straight line along the width direction W of the attached belt 20, and the rigidity of the thin portion 25 is lower than that of the rack 23 or the protrusion 24, the fastening belt 20 is attached to the fastening belt 20 as shown in FIG. When wound in the longitudinal direction L (a direction substantially orthogonal to the width direction W), the entire space occupied by the sphygmomanometer armband 100 can be reduced because it can be rounded with a small diameter.
