Description

(周囲長推定)
本実施の形態による測定部位の周囲長の推定について説明する。図8は、本実施の形態に係る測定部位周囲長Lを推定するために参照されるテーブル433の一例を示す図である。テーブル433には、カフ20の測定部位に対する巻付け状態が“適切巻き”の場合においてカフ圧を所定圧力だけ加圧するのに要する等速加圧の時間と、対応する周囲長Lが格納される。テーブル433のデータは、予め実験等により取得される。図9は、本実施の形態によるカフ圧‐加圧時間特性(適切巻きの場合)のグラフである。図8と図9のデータは、電子血圧計100を用いて多くの被験者からサンプリングしたデータに基づく値を指す。ここで、“適切巻き”とは、測定部位の周囲長に対して巻付けられたカフ20の内径(測定部位である腕の断面の径)による円周の長さが、測定部位の周囲長に対してほぼ等しい状態を指す。本実施の形態では、適切巻きの状態において血圧測定がされると想定する。
(Perimeter estimation)
The estimation of the circumference of the measurement site according to this embodiment will be described. FIG. 8 is a diagram showing an example of a table 433 that is referred to in order to estimate the measurement site circumference L according to the present embodiment. The table 433 stores the constant speed pressurization time required to pressurize the cuff pressure by a predetermined pressure when the winding state of the cuff 20 around the measurement site is “appropriate winding” and the corresponding peripheral length L. . The data in the table 433 is acquired in advance through experiments or the like. FIG. 9 is a graph of cuff pressure-pressurization time characteristics (in the case of appropriate winding) according to the present embodiment. 8 and 9 indicate values based on data sampled from many subjects using the electronic sphygmomanometer 100. Here, “appropriate winding” means that the circumference of the cuff 20 wound around the circumference of the measurement site (the diameter of the cross section of the arm as the measurement site) is the circumference of the measurement site. Is almost equal. In the present embodiment, it is assumed that blood pressure is measured in an appropriate winding state.

周囲長推定部401は、加圧開始後、検出されるカフ圧に基づき、カフ圧が0mmHg(圧力P2)から20mmHg(圧力P3)まで変化するのに要した時間を時計部45によって計測する。そして、計測した時間に基づきテーブル43を検索することにより、対応する周囲長Lを取得する。周囲長Lは補正係数決定部402に与えられる。補正係数決定部402は、周囲長Lと変更後の加圧速度目標Vとに基づきテーブルTBを検索して、対応する補正係数αを読出す。これにより、補正係数αを決定する。 The peripheral length estimation unit 401 measures the time required for the cuff pressure to change from 0 mmHg (pressure P2) to 20 mmHg (pressure P3) by the clock unit 45 based on the detected cuff pressure after the start of pressurization. Then, by searching a table 43 3 based on the time measured to obtain a corresponding perimeter L. The peripheral length L is given to the correction coefficient determination unit 402. The correction coefficient determination unit 402 searches the table TB based on the peripheral length L and the changed pressurization speed target V, and reads the corresponding correction coefficient α. Thereby, the correction coefficient α is determined.

条件が成立しないと判定されると(ステップST13でNO)、処理はステップST1
9に移行する。
If it is determined that the condition is not satisfied (NO in step ST13), the process proceeds to step ST1.
Move to 9.
