(イ) 産業上の利用分野
この考案は、手の指体を圧迫して阻血し、血圧
を測定する指圧迫式の電子血圧計（指用血圧計）
のカフに関する。[Detailed explanation of the invention] (a) Industrial application field This invention is a finger compression type electronic sphygmomanometer (finger sphygmomanometer) that measures blood pressure by compressing the fingers of the hand to prevent blood flow.
regarding the cuff.

いる。(b) Conventional technology Generally, blood pressure monitors measure blood pressure by wrapping a cuff around the upper arm to prevent blood flow from the upper arm. There is a finger sphygmomanometer that you attach to measure your blood pressure. This finger sphygmomanometer wraps a cuff around the finger body, supplies pressurized air to the cuff to stench the finger body, and detects the pulse wave with a photoelectric element while exhausting the pressurized air at a very low speed. It is configured to detect systolic blood pressure and diastolic blood pressure from pulse waves.

る。 As shown in FIGS. 8 and 9, the cuff of this finger sphygmomanometer has a plurality of trapezoidal flexible bags b arranged in parallel on a bottom plate a, and an air chamber in which the insides communicate with each other. When the bottom plate a is made into a cylindrical shape, the side surfaces c of each bag body b are in contact with each other, and each surface d is configured to form a polygonal finger insertion hole e.
(ハ) 考案が解決しようとする問題点
上述したカフにおいて、加圧空気を供給する
と、袋体ｂの表面ｄが指体を押圧することにな
る。しかし、指体の太さは種々あるので、細い場
合には袋体ｂの表面ｄが円弧状に膨張して押圧す
ることになる（第９図参照）。即ち、袋体ｂの内
圧のうち側面ｃに作用するものは互いに相殺さ
れ、表面ｄに作用するものが半径方向に袋体ｂを
変形させることになる。(c) Problems to be solved by the invention In the cuff described above, when pressurized air is supplied, the surface d of the bag body b presses against the finger body. However, since the thickness of the finger body varies, if the finger body is thin, the surface d of the bag body b expands in an arc shape and presses the finger body (see FIG. 9). That is, among the internal pressures of the bag b, those acting on the side surface c cancel each other out, and those acting on the surface d deform the bag b in the radial direction.
従つて、指体の太い場合、内圧がそのまま作用
することになるが、細い場合、袋体表面ｄの膨張
量で指体との隙間吸収することになる。よつて、
指体の圧迫力と袋体ｂの膨張力とが内圧となり、
カフ内の圧力がそのまま血圧値に相当しないこと
になり、正確な測定が困難となつていた。 Therefore, if the finger body is thick, the internal pressure will directly act on it, but if it is thin, the gap between the finger body and the finger body will be absorbed by the amount of expansion of the bag surface d. Then,
The compression force of the finger body and the expansion force of bag body b become the internal pressure,
The pressure inside the cuff does not directly correspond to the blood pressure value, making accurate measurement difficult.
