［従来の技術］ 本来、非観血血圧測定法による血圧測定を行なう場合には、上腕にカフを巻き付けて、血液の流れを阻止するようにカフ内の空気圧を高め、動脈を圧迫する。 [Prior Art] Normally, in the case of blood pressure measurement by the noninvasive blood pressure measurement method, the upper arm by winding a cuff, increasing the air pressure in the cuff to block the flow of blood, pressing an artery. このとき血圧測定誤差を避けるために、カフによる締め付け具合の調節や、測定中にカフの締め付けを緩ませないことが重要である。 To avoid this time the blood pressure measurement error, regulation or condition tightening by cuff, it is important not to loosen the tightening of the cuff during measurement.
一般的に、非観血血圧測定法の一手法であるオシロメトリツク方法においては、脈波成分の最大値に対応するカフ圧を平均血圧として、この最大値の約50％に相当するカフ圧を最高血圧、また最大値の約80％に相当するカフ圧を最低血圧としている。 In general, in the oscillometric metric method is an approach of a non-invasive blood pressure measurement, the cuff pressure corresponding to the maximum value of the pulse wave component as mean blood pressure, the cuff pressure corresponding to approximately 50% of the maximum value the are systolic and a cuff pressure corresponding to approximately 80% of the maximum value and the minimum blood pressure.
［発明が解決しようとする課題］ ところが、上腕の血管内容積を比べ、カフ内空気容量が、例えば血管内容積の10倍以上に大きくなるような場合には、測定した平均血圧の測定値が観血血圧測定法で測定した血圧測定値に比べ、誤差を多く含んだ平均血圧の測定結果が生じてしまう。 [Problems to be Solved] However, compared to intravascular volume of the upper arm, the cuff air volume, for example in the case that greater than 10 times the intravascular volume, the measured value of the average blood pressure was measured compared with blood pressure measurement value measured by invasive blood pressure measurement method, the mean blood pressure measurement result of containing much error occurs.
そこで、従来の血圧測定用カフによる測定時の不具合を以下に説明する。 Therefore, a description trouble at the time of measurement by the conventional blood pressure cuffs and below.
