JP2008237520A - Cuff for sphygmomanometer - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To provide a cuff for a sphygmomanometer, capable of suppressing a positional deviation due to rotation when the cuff is mounted and a positional deviation in the pressure part of an air bag during measurement. <P>SOLUTION: A slip resistance means arranged on the inner surface of the cuff is formed along the longitudinal direction of the cuff, so as to become higher with a part which is highest when the air bag is inflated as a center as a distance increases and to become lower as becoming close to a center part. Consequently, the positional deviation due to the rotation when the cuff is mounted and the positional deviation in the pressed part by the cuff during measurement are suppressed. Besides, marking is performed in a part on the outer surface of the cuff, where the slip resistance means is formed, thereby the position with the slip resistance means formed therein can be recognized. The marking provides a mark for performing measurement with a correct measurement method. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a sphygmomanometer cuff, and more particularly to a wrist sphygmomanometer cuff.

  For example, as a conventional wrist blood pressure monitor, the one disclosed in Patent Document 1 can be cited. As shown in FIG. 8, the wrist type sphygmomanometer disclosed in Patent Document 1 includes a sphygmomanometer cuff 10 wound around the wrist 9 and a main body device.

An inner band 3 is provided on the wrist 9 side of the mounting member 2, and an air bag is accommodated in a space defined by the mounting member 2 and the inner band 3.

  The wrist 9 includes a radius 5, an ulna 6, a radial artery 4, an ulnar artery 7, a plurality of tendons 8, and the like. In this wrist type sphygmomanometer, the radial artery 4 is selectively compressed by the air bag 1 from the radial artery 4. Blood pressure is measured by detecting the pulse wave.

JP 61-11019 A (2 pages, Fig. 3)

  When the sphygmomanometer cuff 10 is attached to the wrist 9 when the sphygmomanometer cuff 10 is tightened, the sphygmomanometer cuff 10 rotates in the direction A, and the air bag 1 is positioned at the optimum position of the artery. Can not do it. If the air bag 1 cannot be positioned at the optimum position, the blood pressure cannot be measured by the correct measurement method, which affects the measurement result.

In order to solve this problem, the present invention adopts the following configuration.
The sphygmomanometer cuff of the present invention is a sphygmomanometer cuff that is attached to a measurement site of a subject and presses the blood vessel of the subject, and includes an air bag for compressing the blood vessel, and an air bag. An inner belt for tightly contacting the measurement site, the inner belt is provided with anti-slip means, and the anti-slip means is formed along the longitudinal direction of the inner belt, and is the highest when the air bag is inflated. It is characterized by becoming higher as it goes away from the center.

  Moreover, it is preferable to have a mounting member for fixing the part to be measured, and to have a marking at a position corresponding to the portion of the mounting member where the anti-slip means is provided.

  The anti-slip means provided in the inner band on the inner surface side of the cuff is curved when viewed from a cross section parallel to the direction of the arm of the sphygmomanometer cuff. By adopting such a shape, when the sphygmomanometer cuff is attached to the wrist, it is easy to fit on the wrist. Therefore, when tightening the sphygmomanometer cuff, it is possible to suppress displacement due to the rotation of the sphygmomanometer cuff.

  When wearing the sphygmomanometer cuff, the anti-slip means, which is curved when viewed from the cross section parallel to the arm direction of the sphygmomanometer cuff, is arranged to fill the gap between the wrist and the inner belt, Since the compression can be performed without causing a positional shift between the inner band of the cuff and the wrist even during the measurement, the compression by the air bag is efficiently transmitted to the radial artery, and more effective compression can be performed.

  The mounting member on the outer surface side of the cuff is provided with a marking at a portion corresponding to the position of the anti-slip means provided on the inner band of the cuff. And the marking is provided also in the position corresponded to the highest part at the time of expansion | swelling of an air bag. It is more preferable that these markings can be distinguished from the cuff attachment member by changing the color, and it is more preferable to change the color of these markings. As a result, the measurer can recognize which part is compressed when the sphygmomanometer cuff is worn, and can measure blood pressure by a more accurate measurement method.

  When the non-slip means is intermittently installed in the inner belt on the inner surface of the cuff, the anti-slip means is provided if the anti-slip means are provided at the highest part when the air bag inflates the sphygmomanometer cuff and on both sides thereof. Even if they are not integral, the same effect can be obtained. More preferably, the area of contact with the wrist is reduced by reducing the surface area of the anti-slip means provided at the highest portion when the air bag of the sphygmomanometer cuff is inflated, so that pain during measurement can be alleviated. .

  In the case where the anti-slip means is intermittently provided on the inner band on the inner surface of the cuff, a plurality of anti-slip means are provided on the highest part of the sphygmomanometer cuff when the air bag is inflated and on both sides thereof. By reducing the surface area of the anti-slip means in this way, the area in contact with the wrist is reduced, so that pain during measurement can be alleviated. The anti-slip means becomes higher as it moves away from the highest part when the air bag is inflated, and the lower the center, the lower the surface of the anti-slip means is not curved. The effect is obtained. Moreover, a non-slip | skid means can be installed in combination with a some raw material by providing in the inner zone of a cuff intermittently. Thereby, the combination which alleviates the pain at the time of a measurement can be applied.

  The anti-slip means provided in the inner band on the inner surface side of the cuff has a shape that becomes higher with increasing distance from the highest portion of the sphygmomanometer cuff when the air bag is inflated, and lowers toward the center. Further, the width of the anti-slip means with respect to the direction parallel to the axis of the arm is the smallest at the highest portion when the air bag is inflated, and increases as the distance increases. Thus, by reducing the surface area of the anti-slip means, it is possible to reduce pain during measurement without degrading the performance of the anti-slip means.

  FIG. 1 is a cross-sectional view showing an embodiment of a sphygmomanometer cuff according to the present invention. The sphygmomanometer cuff 20 of the present invention includes an air bag 1 to which air fed from a main body device is supplied, and a belt-like mounting member 2 for mounting the air bag 1 on the wrist 9 and fixing the wrist 9. Prepare. An inner band 3 is provided on the wrist 9 side of the mounting member 2 to closely attach the air bag 1 to the wrist 9, and the air bag 1 is accommodated in a space defined by the mounting member 2 and the inner band 3. The inner belt 3 is provided with a non-slip means 21 for suppressing a positional deviation due to rotation when the cuff is attached and a positional deviation of the compressed portion of the air bag during measurement.

  The wrist 9 includes a radius 5, an ulna 6, a radial artery 4, an ulnar artery 7, a plurality of tendons 8, and the like. In this wrist type sphygmomanometer, the radial artery 4 is selectively compressed by the air bag 1 from the radial artery 4. Blood pressure is measured by detecting the pulse wave.

  FIG. 2 is a cross-sectional view of the sphygmomanometer cuff of the present invention when the air bag is inflated. The anti-slip means 21 provided on the inner band 3 on the inner surface side of the sphygmomanometer cuff 20 has a curved surface when viewed from a cross-section with respect to a direction parallel to the axis of the arm. These are arranged so as to fill the gap between the wrist 9 and the inner belt 3. For this reason, there is no positional displacement between the cuff inner band 3 and the wrist 9 during the measurement, so that the compression by the air bag 1 is efficiently transmitted to the radial artery 4 as shown by the arrow in FIG. Can be compressed.

  FIG. 3 is a perspective view showing the anti-slip means 21 of the present invention. As shown in FIG. 2 and FIG. 3, the anti-slip means 21 has a shape that increases as it moves away from the highest portion 24 when the air bag 1 is inflated, and lowers toward the center. And has a structure that easily fits the shape of the wrist 9. When the sphygmomanometer cuff of the present invention is attached to the wrist 9, the anti-slip means 21 has a curved surface when viewed from a cross section parallel to the axial direction of the arm.

  This anti-slip means 21 is made of a material such as silicone, polyethylene gel sheet, foam rubber, vinyl chloride foam, pig skin or synthetic leather, sorbosein, polyvinyl chloride, low resilience urethane, flexible urethane foam, etc. Can be used. For example, the height of the anti-slip means 21 is about 1 mm in the vicinity of the portion 24 that is highest when the air bag 1 is inflated. As the air bag 1 is moved away from the highest portion 24 when the air bag 1 is inflated, the anti-slip means 21 becomes higher, and the height of the end portion is about 3 mm.

FIG. 4 is a perspective view showing a modification of the anti-slip means 21 shown in FIG. The anti-slip means 21 is intermittently installed in the inner band 3 on the cuff inner surface side. If the non-slip means 21 is provided at both ends of the portion 24 that is the highest when the air bag of the sphygmomanometer cuff 20 is inflated, the anti-slip means 21 can be installed even if it is not integral. By reducing the surface area of the non-slip means 21 provided in the portion 24 that is highest when the air bag of the sphygmomanometer cuff 20 is inflated, the contact area with the wrist 9 is reduced, so that pain during measurement can be alleviated. . For example, it is possible to alleviate the more pain at the time of measurement by the surface area of the cuff for a blood pressure monitor 20 of the air bag upon inflation be highest in the portion 24 slip means 21 provided in the order of 1cm ² ~4cm ^2.

By reducing the surface area of the anti-slip means 21 in this way, the area in contact with the wrist 9 is reduced, so that pain during measurement can be alleviated. For example, the interval between the anti-slip means 21 is about 1 to 2 mm. The height of the anti-slip means 21 is about 1 mm for the anti-slip means 21 provided at the highest portion 24 when the air bag is inflated, and about 3 mm for the anti-slip means 21 provided at the end. The anti-slip means 21 provided can be appropriately installed between about 1 to 3 mm.

  FIG. 6 is a perspective view showing a modification of the anti-slip means 21 shown in FIG. The anti-slip means 21 provided in the inner band 3 on the inner surface side of the cuff has a shape that becomes higher with increasing distance from the highest portion 24 of the sphygmomanometer cuff 20 when the air bag is inflated, and lowers toward the center. It has become. The lowest part is about 1 mm, and the highest part is about 3 mm. Further, the width of the anti-slip means 21 with respect to the direction parallel to the axis of the arm is the smallest at the highest portion 24 when the air bag is inflated, and becomes larger as the distance increases. Thus, by reducing the surface area of the anti-slip means 21, it is possible to reduce pain during measurement without degrading the performance of the anti-slip means 21 shown in FIG. The width a with respect to the direction parallel to the axis of the arm at the highest portion 24 when the air bag is inflated is, for example, about 1 cm.
