Description

  The present invention relates to a blood pressure measurement cuff that is wound around a pressure upper arm portion or the like in order to measure human blood pressure, and measures blood pressure by compressing the wound portion.

The blood pressure measurement cuff is constructed as a state in which a durable and hardly stretchable rectangular outer bag using a synthetic resin fiber cloth and a rubber inflatable bag extending in the longitudinal direction are accommodated in the outer bag. Has been. The expansion bag and the exterior bag expand and contract by performing operations of injecting air from the outside and discharging the inflowed air to the expansion bag.
The blood pressure measurement cuff is wrapped around a blood pressure measurement site such as a human upper arm, and air is injected from the outside into the expansion bag to inflate the expansion bag and the exterior bag. By this operation, it is known to increase the pressure for tightening the blood pressure measurement site, and then measure the blood pressure by observing the change when releasing the tightening pressure by discharging air from the time of the pressure increase ( For example, patent document 1 Unexamined-Japanese-Patent No. 2009-72278).

  According to the Kortov method (auscultation method), which is widely used as a method for measuring blood pressure in humans with this blood pressure measurement cuff, the cuff pressure is raised above the systolic blood pressure, and once the blood flow is stopped, the cuff is gradually increased. The Korotkoff sound generated when the pressure is reduced and the blood flow is resumed is detected on the peripheral side, which is downstream of the cuff, and the internal pressure of the air bag for ischemia is determined as the systolic blood pressure (maximum blood pressure). The internal pressure of the air bag for ischemia in which the Korotkoff sound has disappeared is obtained as the diastolic blood pressure value (minimum blood pressure value).

In the Korotkoff sphygmomanometer, sound generated by noise generated during blood pressure measurement (sound generated when the inflatable bag and outer bag come in contact, cuff tube that supplies air to the inflatable bag, inflated bag and outer bag are rubbed The noise generated by these noises, or the sound generated by vibrations from inflatable bags, exterior bags, and cuff tubes) is caused by noise because the frequency components of these sounds are close to those of Korotkoff sounds. There is a problem that the sound is likely to be erroneously detected as a Korotkoff sound (Japanese Patent Application Laid-Open No. 2009-178249, Japanese Patent Application Laid-Open No. 2008-178542, Japanese Patent Application Laid-Open No. 2008-178541). ).
In addition, as described above, the blood pressure measurement cuff can be attached by sewing a pair of flat fasteners on the outer surface of the outer bag and detachably wrapping it around the human upper arm using this. Since the burr generated by the pair of flat fasteners gives an uneasy feeling to the rightee, it is necessary to prevent this kind of noise from occurring.

In the oscillometric method, after the cuff is pressurized and then depressurized, the blood pressure value is determined by observing the fluctuation of the cuff pressure reflecting the vibration of the blood vessel wall synchronized with the heartbeat. Generally, the cuff pressure when the pressure pulse wave suddenly increases is the maximum blood pressure, and the cuff pressure when the pressure pulse wave rapidly decreases is the minimum blood pressure (Japanese Patent Application Laid-Open No. 2009-72278).
The frequency component of pressure fluctuation used for measurement is considerably lower than the frequency component of Korotkoff sound. In the oscillometric method, the frequency component of the pressure fluctuation used for the measurement is not problematic because it is different from the frequency of the sound generated by the noise generated during the blood pressure measurement described in the Korotkoff method. The However, for the rightee, it is necessary to prevent the generation of this kind of noise because it causes anxiety that this kind of noise occurs. Moreover, since the burr sound generated by the pair of flat fasteners gives an uneasy feeling to the rightee, it is necessary to prevent this kind of noise from occurring.

About the blood pressure measurement cuff, as a result of each person's use at the time of use, it has been calculated | required that it is a disposable form which cannot avoid an unsanitary state and can be disposed of. Specifically, it is as follows.
A general cuff structure includes an air-tight air bag and an outer skin that is an inflatable bag that covers and protects the air bag. The outer skin has a hook-and-loop hook fastener (a hook-and-loop fastener corresponding to this is provided on the back surface) for maintaining the state when wound around the upper arm. Therefore, in the inventions of JP-A-7-233941 and Japanese Patent No. 3202421, there is known a blood pressure measurement cuff that makes it easy to attach or detach the air bag to or from the outer skin and makes the outer skin part disposable. ing. In this blood pressure measurement cuff, the air bag and the inflatable bag are configured separately, and by using a nonwoven fabric such as polypropylene, nylon, polyester, or polyethylene as the material of the outer skin, it is inexpensive and has air permeability, Describe the realization of a disposable skin. In order to reduce the noise, it is not effective to use this material. Also in this invention, a hook-and-loop fastener is used, and the above-mentioned problems remain.
Invention of a disposable blood pressure measurement cuff formed by laminating a plurality of sheets having the same skin portion and water-absorbing and water-absorbing properties, and having a waterproof covering sheet closely bonded to one side thereof (Patent Document 6) -579). In this case, it is not appropriate that a plurality of sheets are laminated to sufficiently hold the interior and exterior, and the problem pointed out in the invention is not solved. Invention of a blood pressure measurement cuff in which an outer component of a non-stretchable paper and an inner component of a stretchable thermoplastic material are sealed to form an inflatable hollow chamber at corresponding peripheral edges. The same applies to Japanese Patent Application Laid-Open No. 8-317910.
Similarly, the invention of the following disposable blood pressure measurement cuff is known. A water-permeable surface layer, a water-absorbing layer formed of a water-absorbing material following the surface layer, and a surface fastener on the back surface opposite to the surface layer. An invention of a disposable blood pressure measurement cuff in which a rubber bag having a predetermined size is provided from one end in the middle, and an outer extending portion and a bag peripheral portion of the surface material are welded at once by a welder (Patent Document 8 Japanese Patent Laid-Open No. HEI 9-9) 2013340, Japanese Patent No. 36049797). Although a water-permeable surface layer and a water-absorbing layer formed of a water-absorbing material following the surface layer are set, the above problems have not been solved.
Moreover, in these inventions, as a result of sticking to disposable and disposable shapes or materials, attention is not paid to the occurrence of noise in blood pressure measurement, which is not sufficient as a blood pressure measurement cuff.

  The blood pressure measurement cuff has a double structure in which an expansion bag is accommodated in an exterior bag. The expansion bag is fixedly disposed inside, and the inner periphery side sheet 48 and the outer periphery side sheet 50 are arranged with the inner periphery side sheet 48 facing downward. It is placed on top of each other, and the outer peripheries of each other are welded together to form an end (Patent Document 10 Japanese Patent Application Laid-Open No. 2004-195074 (the end shown in FIGS. 3 and 5), Japanese Patent Application Laid-Open No. 2000-51158 (the end portion shown in FIG. 4), Japanese Patent Application Laid-Open No. 2008-99944 (the end portion shown in FIG. 3 and FIG. 4), and the like. In these cases, the outer bag and the inflatable bag are separated from each other, and in order to fix the end part or to fix the outer bag and the inflatable bag only at the end part, the sound generated by the noise generated during blood pressure measurement (inflated Sound generated by contact between the bag and the outer bag, rubbing sound generated by rubbing the cuff tube supplying air to the inflatable bag and the inflated bag and outer bag, or vibration caused by the inflated bag, outer bag, and cuff tube Cannot be prevented.

  Also, when fixing the blood pressure measurement cuff to the measurement site, the protective seal on the surface of the adhesive layer is removed, the adhesive is exposed, and the adhesive is exposed to the position where the microphone is positioned on the artery of the measurer's arm And the position of the arrangement end of the adhesive layer of the cuff is determined so that the microphone is positioned at this position. Then, the adhesive layer is pressed against the skin surface by pressing the end of the cuff at this position, and the cuff is positioned and locked by the adhesive force of the adhesive layer. Next, the cuff is wrapped around the arm, and the final other end is fixed with a hook-and-loop fastener. An invention of a disposable blood pressure measurement cuff having this shape is known (Patent Document 9 Japanese Patent Laid-Open No. 10-165378). When using such a hook-and-loop fastener, the use of hook-and-loop fasteners cannot prevent the sound of burr generated during use from interfering with the measurement. It has been pointed out as a problem. A solution to this point has been sought.
