Description

  The present invention relates to a cuff for a blood pressure information measuring device, and more particularly to a cuff that compresses a part such as an arm or wrist of a person to be measured for blood pressure measurement.

  Conventionally, as this type of cuff for blood pressure information measuring apparatus, for example, as disclosed in Patent Document 1 (Japanese Patent Laid-Open No. 11-299749), an air bag and a plurality of plates are arranged in a belt-like cloth. It has been known. The plurality of plates are provided side by side along the outer periphery of the air bag, and are connected to each other by a hinge-type connecting portion so as to be rotatable. According to such a configuration, a plurality of plates are connected to each other, and even if the air bag is inflated, the air bag does not bulge outward (on the side opposite to the measurement site). As a result, a sufficient compression force is applied to the measurement site.

  Patent Document 2 (Japanese Unexamined Patent Application Publication No. 2009-183629) also discloses a cuff having a similar structure and a similar function.

Japanese Patent Laid-Open No. 11-299749 JP 2009-183629 A

  However, in the configuration of the cuff, a plurality of plates are connected by a connecting portion having a hinge structure. For this reason, it can be said that productivity is not good because the structure is complicated and there are many types of parts. Further, it is required that the individual plates to be connected have a certain thickness and width (dimension in the circumferential direction), and there is a problem that the cuff becomes large as a whole. In addition, the air bag may be broken and wrinkles or the like may occur at the pivoted portion of the hinge, and the compression force may not be correctly applied to the measurement site.

  Accordingly, an object of the present invention is to provide a cuff for a blood pressure information measuring device that has good productivity, can be configured in a small size, and can correctly apply a compression force to a measurement site.

In order to solve the above problems, a cuff for a blood pressure information measuring device of the present invention is
A blood pressure information measuring device cuff wrapped around a measurement site for blood pressure measurement,
An inner cloth made of a stretchable material that is wound in contact with the measurement site;
A fluid bag arranged along the outer peripheral surface of the inner cloth, for compressing the measurement site;
A support member that covers the fluid bag and is arranged in the circumferential direction along the inner cloth, and made of a flexible material;
A plurality of rigid members attached to the support member side by side with respect to the circumferential direction, each having an elongated shape along a direction in which the measurement site wound around the inner cloth should extend;
An outer cloth that is combined with the inner cloth and forms a cloth bag containing the fluid bag, the support member, and the rigid member;
As the support member bends, the distance between the plurality of rigid members is allowed to change in the circumferential direction,
At least one of the outer cloth and the support member is made of a non-stretchable material in the circumferential direction.

  Here, “inner cloth” and “outer cloth” include not only the case of being made of cloth but also the case of being made of one or more layers of resin.

  The cuff for a blood pressure information measuring device of the present invention is wound so as to surround the measurement site with the inner cloth in contact with the measurement site. Here, as the support member bends, the distance between the plurality of rigid members is allowed to change with respect to the circumferential direction. Therefore, the cuff is wound so as to surround the measurement site without the winding of the plurality of rigid members. When the cuff is wound around the non-measurement site, both ends in the circumferential direction of the outer fabric are at least overlapped and fixed by, for example, a known surface fastener. As a result, the cuff is wound in close contact with the portion to be measured.

  In this state, fluid (typically air) is supplied from the outside of the cuff to the fluid bag through, for example, piping, and the measurement site is compressed. Here, the inner cloth is made of a stretchable material, and at least one of the outer cloth and the support member is made of a non-stretchable material in the circumferential direction. Therefore, the fluid bag is restricted from expanding to the side opposite to the measurement site, and tends to expand toward the measurement site. As a result, a sufficient compression force can be applied to the measurement site. Further, the rigid member having an elongated shape along the direction in which the measurement site wound around the inner cloth should extend does not deform because it has rigidity. That is, the both ends of the rigid member do not bend in the direction away from the measurement site. Therefore, a uniform compression force can be applied to the measurement site in the direction in which the measurement site extends.

  In the cuff for a blood pressure information measuring device, the plurality of rigid members are attached to the support member side by side in the circumferential direction. As the support member bends, the distance between the plurality of rigid members is allowed to change with respect to the circumferential direction. That is, the plurality of rigid members are not connected by a hinge structure, but the plurality of rigid members are only attached to the support member side by side in the circumferential direction. Therefore, the structure is simplified and the number of parts is reduced. As a result, parts can be easily procured and assembled, and productivity is improved. Moreover, each rigid member can set thickness and the circumferential direction dimension small compared with the plate in a prior art document. Therefore, the cuff can be made compact as a whole. Further, since the plurality of rigid members are not connected by a hinge structure, they are not folded into an air bag and wrinkles or the like are not generated at the pivoted portion of the hinge. Therefore, the compressive force can be applied more correctly to the measurement site.

In the cuff for the blood pressure information measuring device of one embodiment,
A pipe for supplying fluid to or discharging fluid from the fluid bag is provided through the outer cloth and the support member and through the gap between the rigid members,
The fluid bag is fixed to the support member only around the pipe.

  In the cuff for a blood pressure information measurement device according to this embodiment, the fluid bag is fixed to the support member only around the pipe. Therefore, the fluid bag is fitted to the measurement site via the inner cloth. Therefore, the compressive force can be applied more correctly to the measurement site.

  In the cuff for a blood pressure information measurement device according to one embodiment, the plurality of rigid members are attached to the outer peripheral surface of the support member with an adhesive.

  In the cuff for a blood pressure information measurement device according to this embodiment, the plurality of rigid members are attached to the outer peripheral surface of the support member with an adhesive. Therefore, at the manufacturing stage, the plurality of rigid members can be easily attached to the support member.

In the cuff for the blood pressure information measuring device of one embodiment,
The support member is made of resin,
The plurality of rigid members are covered with or embedded in the support member.

  In the cuff for a blood pressure information measurement device according to this embodiment, the plurality of rigid members are covered or embedded in the support member. Therefore, the support member and the plurality of rigid members can be prepared as a set by covering or embedding the plurality of rigid members with a support member made of resin at the manufacturing stage. Thereby, this cuff for blood pressure information measuring devices can be assembled easily.

  In the cuff for a blood pressure information measurement device according to one embodiment, the plurality of rigid members have the same shape.

  In the cuff for a blood pressure information measurement device according to this embodiment, the plurality of rigid members have the same shape. Therefore, procurement and assembly of parts are further facilitated, and productivity is further improved.

  In the cuff for a blood pressure information measurement device according to one embodiment, the shape of the rigid member is a rod shape having a circular cross section.

  In the cuff for a blood pressure information measurement device according to this embodiment, the shape of the rigid member is a rod having a circular cross section. Therefore, when the inner cloth is wound around the measurement site with the inner fabric in contact with the measurement site, the plurality of rigid members do not interfere with each other as the support member bends. The plurality of rigid members do not become an obstacle to winding. Therefore, the cuff is easily wound around the part to be measured.

  In the cuff for a blood pressure information measurement device according to one embodiment, the plurality of rigid members are attached to the support member in close contact with each other in the circumferential direction.

  In the cuff for a blood pressure information measurement device according to this embodiment, the plurality of rigid members are attached to the support member in close contact with each other in the circumferential direction. Accordingly, the gap between the plurality of rigid members can be reduced with respect to the circumferential direction, and a uniform compression force can be applied to the measurement site.

  As is clear from the above, the cuff for a blood pressure information measuring device of the present invention has good productivity, can be configured in a small size, and can correctly apply a compressive force to a measurement site.

It is a figure which expands and shows the principal part of the said cuff. It is a figure which shows the modification of the principal part of the said cuff. It is a figure which illustrates the various shapes which the cross section of the rigid member contained in the said cuff can take.

  Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments.

  FIG. 1 shows an overall configuration of a wrist sphygmomanometer 100 including a cuff for a blood pressure information measuring device (indicated by reference numeral 10) according to an embodiment of the present invention. For easy understanding, a part of the cuff 10 is shown in a transparent state so that the inside of the cuff 10 can be seen. FIG. 2 shows a state in which the sphygmomanometer 100 is attached to the wrist 90 as a part to be measured.

  As can be seen from FIGS. 1 and 2, the sphygmomanometer 100 is integrally provided with a main body 110 and a cuff 10 wound around the wrist 90. The main body 110 includes a pump for supplying air to the cuff 10 (more precisely, an air bag 40 to be described later), an exhaust valve for discharging air from the cuff 10, and blood pressure measurement (systole as blood pressure information). A control unit for controlling the measurement of blood pressure value and diastolic blood pressure value, a battery for supplying electric power to these components, and the like are mounted (all of which are not shown).

  The cuff 10 includes an inner cloth 61, an air bag 40 as a fluid bag for pressing the wrist 90, a support member 20, a plurality of rigid members 30, 30,.

  The inner cloth 61 is made of a stretchable material so as not to hinder the expansion of the air bag 40, and is wound in a band shape in contact with the wrist 90. In this example, the inner fabric 61 is made of a knitted fabric.

  The air bag 40 is arranged in a belt shape along the outer peripheral surface 61 a of the inner cloth 61. This air bag 40 consists of a bag-shaped member formed, for example using the resin sheet. The dimension of the air bag 40 in the circumferential direction A is set to, for example, about 160 mm so as to be tightly wound around the wrist. The dimension of the air bag 40 in the width direction (direction B in FIG. 1) is set to about 50 mm so that the artery can be sufficiently compressed, for example.

  The support member 20 covers the air bag 40 and is arranged in a belt shape in the circumferential direction A along the inner cloth 61. The support member 20 is made of a flexible material. In this example, as the support member 20, a commercially available vinyl tape having an adhesive applied to one side 20a is used. In accordance with the size of the air bag 40, the size in the circumferential direction A of the support member 20 is set to about 160 mm, and the size in the width direction B is set to about 50 mm.

  The plurality of rigid members 30, 30,... Have the same shape that is elongated along the direction B in which the wrist 90 wound around the inner cloth 61 should extend. In this example, each rigid member 30 has a rod shape having a circular cross section with a diameter of about 1 mm. The length of each rigid member 30 (dimension in the direction B) is set to about 50 mm, which is the same as the dimension of the air bag 40.

  The plurality of rigid members 30, 30,... Are arranged in close contact with the surface (adhesive surface) 20a to which the adhesive of the support member 20 is applied, as can be clearly understood from FIG. Easy to install. When the cuff 10 is wound around the wrist 90, the plurality of rigid members 30, 30,... Are aligned in the circumferential direction A along the bonding surface 20a of the support member 20, as shown in FIGS. .

  The outer cloth 62 is made of a non-stretchable material, for example, a fabric that is tarpaulin laminated on one surface, extending in a belt shape in the circumferential direction A. The outer cloth 62 is sewn together with the inner cloth 61 at the periphery. Thereby, the cloth bag 60 is comprised. The cloth bag 60 includes the air bag 40, the support member 20, and the rigid member 30. In this example, the dimension of the outer cloth 62 in the circumferential direction A is set to about 200 mm so that at least both ends overlap after being wound around the wrist. The dimension in the width direction B of the outer cloth 62 and the inner cloth 61 is set to about 60 mm so as to cover the air bag 40.

  As shown in FIG. 2, a known surface fastener 50 is provided in a region where both ends in the circumferential direction of the outer cloth 62 overlap.

  A pipe 70 is provided between the air bag 40 and the main body 110. The pipe 70 is connected to the air bag 40 through the outer cloth 62 and the support member 20 and through the gap 31 between the rigid members 30. Air as a fluid can be supplied to the air bag 40 from the main body 110 through the pipe 70, or the fluid can be discharged from the air bag 40. The air bag 40 is fixed to the support member 20 only around the pipe 70. A portion of the air bag 40 away from the pipe 70 is not fixed to the support member 20 or the inner cloth 61.

  The cuff 10 is wound around the wrist 90 with the inner cloth 61 in contact with the wrist 90. Here, the distance between the plurality of rigid members 30, 30,... Is allowed to change with respect to the circumferential direction A as the support member 20 bends. Moreover, the cross-sectional shape of the rigid member 30 is circular. Therefore, the plurality of rigid members 30, 30,... Do not interfere with each other, and the plurality of rigid members 30, 30,. Thus, the cuff is easily wrapped around the wrist 90. When the cuff 10 is wound around the non-measurement site, both ends in the circumferential direction of the outer cloth 62 overlap each other and are fixed by the planar fastener 50. As a result, the cuff 10 is wound in close contact with the wrist 90.

  In this state, air is supplied to the air bag 40 from the outside of the cuff 10 through the pipe 70, and the wrist 90 is compressed. Here, the inner cloth 61 is made of a stretchable material, and the outer cloth 62 is made of a non-stretchable material. Therefore, the inflation of the air bag 40 toward the side opposite to the wrist 90 is restricted, and the air bag 40 tends to expand toward the wrist 90. Thereby, sufficient compression force can be applied to the wrist 90. Further, the rigid member 30 having an elongated shape along the direction B in which the wrist 90 wound around the inner cloth 61 should extend does not deform because it has rigidity. That is, both ends of each rigid member 30 are not bent in a direction away from the wrist 90. In addition, the plurality of rigid members 30, 30,... Are attached to the support member 20 in close contact with each other in the circumferential direction A. Therefore, with respect to the direction B in which the wrist 90 extends, the gaps between the plurality of rigid members 30, 30,... Can be reduced, and a uniform compression force can be applied to the wrist 90.

  In the cuff 10, the plurality of rigid members 30, 30,... Are attached to the support member 20 side by side in the circumferential direction A. And it is permitted that the distance between the plurality of rigid members 30, 30,... Changes in the circumferential direction A as the support member 20 bends. In other words, the plurality of rigid members 30, 30,... Are not connected by a hinge structure, but the plurality of rigid members 30, 30,... Are only attached to the support member 20 side by side in the circumferential direction A. It is. Further, the plurality of rigid members 30, 30,... Have the same shape. Therefore, the structure is simplified and the number of parts is reduced. As a result, parts can be easily procured and assembled, and productivity is improved. In addition, each rigid member 30 can be set to have a smaller thickness and a dimension in the circumferential direction A than the plate in the prior art document. Therefore, the cuff 10 can be made compact as a whole. In addition, since the plurality of rigid members 30, 30,. Therefore, the pressing force can be applied to the wrist 90 more correctly.

  Further, in the cuff 10, as described above, the air bag 40 is fixed to the support member 20 only around the pipe 70. Therefore, the air bag 40 fits to the wrist 90 via the inner cloth 61. Therefore, the pressing force can be applied to the wrist 90 more correctly.

  In the above example, the outer cloth 62 is made of a non-stretchable material and the support member 20 is made of a commercially available vinyl tape (that is, a stretchable material), but this is not restrictive. It suffices that at least one of the outer cloth 62 and the support member 20 is made of a material in the circumferential direction A. As a result, the inflation of the air bag 40 toward the side opposite to the wrist 90 is restricted, and the air bag 40 tends to expand toward the wrist 90. Thereby, sufficient compression force can be applied to the wrist 90.

  In the above example, the plurality of rigid members 30, 30,... Are attached to the adhesive surface 20a of the support member 20 made of a commercially available vinyl tape. However, the present invention is not limited to this. For example, the support member 20 is made of resin, and a plurality of rigid members 30, 30,... May be covered or embedded in the support member 20 as illustrated in FIG. In this case, the support member 20 and the plurality of rigid members 30, 30,... Are covered with the support member 20 made of resin or embedded in the support member 20 at the manufacturing stage. Can be prepared as a set. Thereby, this cuff 10 can be assembled easily.

  In the above example, the cross-sectional shape of each rigid member 30 is circular as shown in FIG. 5A, but is not limited thereto. The cross-sectional shape of each rigid member 30 may be, for example, a rectangle as shown in FIG. 5 (b), an ellipse as shown in FIG. 5 (c), or FIG. 5 (d). As shown in FIG. 4, the shape may be composed of a semi-elliptical apex 30t and a rectangular lower portion 30b.

  The above-described embodiments are merely examples, and various modifications are possible within the scope of the present invention.
