【発明の詳細な説明】 （イ）産業上の利用分野 この発明は、血圧測定の際に動脈を圧迫し阻血するのに
使用される腕帯（カフ）であって、カフの容積に応じた
微速排気が行える血圧計用腕帯に関する。DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to an arm girdle (cuff) used for compressing and blocking blood in an artery at the time of blood pressure measurement, and is adapted to the volume of the cuff. The present invention relates to a sphygmomanometer armband capable of performing a slow exhaust.
（ロ）従来の技術 通常、血圧の測定は、腕帯（カフと称するゴム製空気

の測定では、この減圧過程で生ずる脈波振幅を脈波セン
サにより検出することで、血圧値が測定されている。(B) Conventional technology Normally, blood pressure is measured by wrapping an armband (a rubber bladder called a cuff) around the upper arm and pressurizing the cuff with a pressure pump to a value higher than the systolic blood pressure of the subject. After squeezing and blocking blood,
The cuff internal pressure is gradually reduced by the slow exhaust valve. Here, for example, in the K-sound system measurement, the generation / disappearance of K sound (blood flow sound called Korotkoff sound) generated in the decompression process
A blood pressure value is measured by detecting with a sound sensor. Further, in the vibration-type measurement, the blood pressure value is measured by detecting the pulse wave amplitude generated in the depressurization process with a pulse wave sensor.

気弁による手動方式、或いは計器本体の空気系に内蔵さ
れている排気弁による自動方式により行われる。When reducing the cuff pressure at the time of measurement, usually a manual method with an exhaust valve provided in an air balloon (air pump) attached to the cuff via a tube, or an automatic method with an exhaust valve built into the air system of the instrument body Done by.
（ハ）発明が解決しようとする問題点 一般に、血圧測定に際し、動脈を阻血するカフは、被測
定者の腕の太さに対しカフ幅が狭かったり、或いはカフ
の寸法が長尺すぎる場合等、つまりカフが腕に対応した
大きさでないと、強い圧をかけなければならず、測定血
圧が高すぎることとなることが知られている。(C) Problems to be Solved by the Invention Generally, when measuring blood pressure, a cuff that interrupts an artery has a narrow cuff width relative to the thickness of the arm of the subject, or the cuff is too long. That is, it is known that unless the cuff has a size corresponding to the arm, strong pressure must be applied and the measured blood pressure becomes too high.
そこで、カフは通常、計器本体と別体とされ、被測定者
の腕の太さに対応する数種類の寸法のカフが用意されて
いる。被測定者は腕の太さに対応したカフを選択して、
加圧ポンプに接続することで測定を実行している。Therefore, the cuff is usually separated from the main body of the instrument, and there are prepared cuffs having several sizes corresponding to the thickness of the arm of the subject. The person to be measured selects a cuff corresponding to the thickness of the arm,
The measurement is performed by connecting to a pressure pump.
ところで、カフの減圧速度は通常、例えば２乃至5mmHg/
sec程度の微速排気が最も適当とされ、この微速排気は
一定の速度で直線的に減圧していく必要がある。そのた
め、従来の微速排気弁（送気球内の弁或いは計器の空気
系内の弁）は、それぞれこの理想的な排気速度に設定し
てある。By the way, the decompression speed of the cuff is usually, for example, 2 to 5 mmHg /
Fine speed exhaust of about sec is the most suitable, and it is necessary to decompress this fine speed exhaust gas linearly at a constant speed. Therefore, the conventional slow-speed exhaust valve (the valve in the air supply bulb or the valve in the air system of the instrument) is set to this ideal exhaust speed.
このため、同一寸法のカフを使用して減圧する場合は、
一定微速度で減圧することが出来、問題はないが、寸法
の異なるカフを使用する場合には、変更したカフ容積に
対応して微速排気弁の排気速度を再設定する必要があ
る。For this reason, when decompressing using a cuff of the same size,
It is possible to reduce the pressure at a constant fine speed, and there is no problem, but when using cuffs of different dimensions, it is necessary to reset the exhaust speed of the slow exhaust valve in accordance with the changed cuff volume.
ところが、この排気速度の再設定（調整）作業は使用者
にとって煩わしい許かりでなく、実際上困難である。こ
の結果、カフ容量に対応しない排気速度で血圧測定を実
行することとなり、適正な血圧値が得られない等の不利
があった。However, this resetting (adjusting) work of the exhaust speed is not a troublesome operation for the user and is actually difficult. As a result, blood pressure measurement is performed at an exhaust velocity that does not correspond to the cuff capacity, which is disadvantageous in that an appropriate blood pressure value cannot be obtained.
この発明は、従来のものがもつ、以上のような問題点を
解消させ、大小寸法の異なるカフを使用した場合でも、
常にカフ容積に対応した一定の微速排気が行え、正確な
血圧測定が実行できる血圧計用腕帯を提供することを目
的とする。The present invention solves the above problems of the conventional one, and even when using cuffs of different sizes,
