And blood pressure is measured.

  • the blood pressure measurement device disclosed in Patent Document 1 is the smallest arm circumference of the portion to be measured (the thinnest that is expected to be measured). Arm circumference of the arm), and as shown in FIG. 3 of Patent Document 1, in the case of a thick arm, it is designed to cover at least 50% of the circumference of the arm to prevent the collision. It was general. Therefore, the blood pressure measurement device as in Patent Document 1 performs measurement while measuring the blood pressure of the thinnest arm assumed to be measured while the measurement air bag compresses almost the entire circumference of the measured portion. When measuring an arm having a longer arm circumference (thick arm), the measurement air bag is not in contact with the entire circumference of the portion to be measured, and presses a part of the arm circumference into a C-shape. Measurement will be performed.
  • the compression-fixing air bags are independently arranged in the upper and lower directions in the circumferential direction of the arm, and the upper and lower pressure-fixing air bags are independently provided in the measured portion.
  • the curler is uniformly expanded toward the central direction, and the curlers in contact with the expanded portions are uniformly reduced in diameter.

If it comes into contact with the thick part of the part to be measured, the diameter cannot be reduced further toward the thin part. Accordingly, the measurement air bag is not pressed against the thin part of the part to be measured at all, or even if it is pressed, the pressing force is weakened. There was a problem. Therefore, the blood pressure measurement device of Patent Document 1 is provided with a plurality of compression-fixing air bags that inflate independently in the longitudinal direction of the measurement target portion, thereby reducing the diameter of the curler in the thick portion of the measurement target portion. By changing the amount of diameter reduction in the thin part, that is, by increasing the amount of diameter reduction in the thin part, the pressure fixing air bag is pressed against the thick part and thin part of the part to be measured with an equal pressing force. .

  • the blood pressure measurement device of Patent Document 1 measures the upper arm portion (measured portion) whose arm circumference is shorter (thin) than the length in the arm circumference direction of the measurement air bag. Since both ends of the C-shape collide with each other and there is a possibility that the measurement accuracy may be adversely affected, the upper arm portion thinner than the length in the arm circumferential direction of the measurement air bag cannot be measured.

  • the measurement air bag is a part of the arm circumference of the upper arm part.
  • appropriate blood pressure measurement cannot be performed because the part is not compressed. That is, when a part of the outer periphery of the arm where the blood vessel to be blocked exists is not compressed, the force applied to the outer periphery of the blood vessel from the measurement air bag escapes outward from the outer peripheral portion of the blood vessel that is not compressed.
  • the blood pressure measuring apparatus of this type may not be able to perform accurate blood pressure measurement due to an increase in the pressure of the measurement bladder necessary for ischemia.

Therefore, in the blood pressure measurement device of Patent Document 1, when a blood vessel is disposed at a position where the measurement air bag on the circumference of the arm does not contact during blood pressure measurement, the blood vessel is not appropriately compressed, and accurate blood pressure measurement is performed. There was a problem in that it could not be done. From the above points, it can be said that blood pressure measurement is desirably performed while pressing the blood vessel from all directions over the entire circumference of the arm.
  • the curler for compressing and fixing the measurement air bag in the blood pressure measurement device of Patent Document 1 has a substantially cylindrical shape obtained by rounding one flexible member. If the measurement air bag is not circular, the measurement air bag is pressed strongly against the protruding part of the upper arm part through the cylindrical curler and weakly pressed against the recessed part of the upper arm part. There was a case where it felt uncomfortable due to excessive pressing force on the protruding part.

Therefore, in the blood pressure measurement device of Patent Document 1, the curler is reduced in diameter by a single compression-fixing air bag disposed in the longitudinal direction of the upper arm portion, and the tapered upper arm portion whose thickness changes in the longitudinal direction is provided. In the case of pressing, the curler cannot incline properly inward toward the thin portion of the upper arm while the measurement air bag is brought into close contact with only the thick portion of the upper arm.

Ledit sphygmomanomètre automatique (1) possède une large plage de mesure et permet d'obtenir une précision de mesure élevée. Ce sphygmomanomètre automatique (1) présente trois feuilles de plaques intermédiaires souples (8a-8c) ou davantage, disposées en forme de spirale, lesdites plaques intermédiaires (8a-8c) présentant des bases (8a1-8c1) fixées au côté interne d'un corps tubulaire circulaire (6) et possédant en outre des têtes s'étendant individuellement dans la même direction le long de la périphérie interne du corps tubulaire (6). Ledit sphygmomanomètre possède également des coussins d'air (16a-16c), destinés à comprimer les plaques intermédiaires, et disposés entre le corps tubulaire (6) et les plaques intermédiaires, ainsi que des coussins d'air (15a-15c) conçus pour la mesure, disposés sur le côté interne des plaques intermédiaires. La tête (8a2-8c2) de chaque plaque intermédiaire est placée de manière à se trouver radialement vers l'intérieur et à être chevauchée par au moins la base (8b1, 8c1, 8a1) d'une autre plaque intermédiaire adjacente à la tête (8a2-8c2), dans la direction selon laquelle s'étend la tête (8a2-8c2).
