していた。[Prior Art] Normally, when blood pressure is measured using a non-invasive method, a cuff is wrapped around the arm to compress the artery so as to block the flow of blood. At this time, in order to avoid blood pressure measurement errors, it is important to adjust the tightness of the cuff and not to loosen the cuff during measurement. Also, in order to reliably block the flow of blood, the grip on the arm was particularly strong.

を有している。 FIG. 1 is a diffusion exploded view of the blood flow sound collecting device according to this embodiment, and FIG. 2 is a cross-sectional view taken along the line AA in FIG. 1. In FIGS. 1 and 2, reference numeral 10 denotes a sound collection section for blood flow sounds, which includes a pair of circular microphones 11 and cords 12 connected to the sides of these microphones. A holding body 13 holds this sound collecting section 10,
The outer shape is approximately rectangular, and the height is approximately equal to the thickness of the microphone 11. Also, the holding body 1
In the longitudinal direction of the microphone 3, two circular fitting portions 14 having a diameter approximately the same as the outer diameter of the microphone 11 are provided in one row. Furthermore, as shown in the AA cross section of the holder 13 shown in FIG. 2, the fitting part 14 has a shape that widens toward the contact surface P (indicated by the arrow) to the living body.
また、保持体１３における生体との被接触面P'

いる。 In addition, the contact surface P′ of the holding body 13 with the living body is
(indicated by an arrow), a Y-shaped cord guide groove 15 for guiding the cord 12 is provided approximately in the center.

触面が圧接力を分散してくれる。 Furthermore, Fig. 4 shows a side view of actual blood flow being detected using this blood flow sound collection device.
In the figure, the blood flow sound collecting device is sandwiched between the cuff 16 and the arm 17, and the cuff 16 is already in a pressurized state. At this time, the microphone 11 is held by the holder 13 and the contact area is widened, so that the bulge 18 on the skin caused by the pressure contact of the microphone 11 can be reduced. Furthermore, the contact surface of the flat arm 17 of the holding body 13 with the biting portion 19 applied to the skin by the holding body 13 disperses the pressing force.
また、嵌装部１１を腕との接触面に対して末広
がりに形成したため、マイクロフオン１１に遊嵌
されたような自由を与え、これによつて腕の形状
に対して柔軟な適応を可能にさせた。 In addition, since the fitting part 11 is formed to widen towards the surface that comes into contact with the arm, it gives the microphone 11 the freedom of being loosely fitted, thereby making it possible to flexibly adapt to the shape of the arm. I let it happen.
このように、血流音集音装置における生体との
接触面積を広げることで測定時におけるマイクロ

接触面によつて生体に与える痛みは殆どない。 In this way, by widening the contact area of the blood flow sound collection device with the living body, it is possible to prevent the microphone from shifting its position during measurement, and this wide contact surface causes almost no pain to the living body.
また、保持体の柔軟性により、腕の形状に充分
適応するように変形できる。 Additionally, the flexibility of the holder allows it to be deformed to suit the shape of the arm.
さらに、複数のマイクロフオンを用いる場合に

ことがなくなる。 Furthermore, when using multiple microphones, there is no movement between the microphones that would narrow the gap between them, thereby eliminating the pain of picking at the skin, and using a single microphone. Even if there is a problem, the wide contact surface provided by the holder disperses the pressing force on the arm, eliminating the possibility of pain.
また、血流音の検出時において、マイクロフオ
ンに加わる応力を保持体に分散させる効果がある

めるような心配が必要ない。 Further, when detecting blood flow sound, there is an effect of dispersing the stress applied to the microphone to the holder, and since the cord guide groove is provided, there is no need to worry about damaging the cord.
さて、本実施例の変形例として第５図のような
血流音集音装置が考えられる。 Now, as a modification of this embodiment, a blood flow sound collecting device as shown in FIG. 5 can be considered.

である。 FIG. 5 is an exploded view of diffusion in which an adhesive tape 20 is added above the holder 13 and the sound collector shown in FIG. 1, and FIG. 6 is a schematic cross-sectional view showing the overall configuration. In FIGS. 5 and 6, the holding body 1
After the sound collecting section 10 is mounted inside the microphone 3, a tape 20 is attached to the upper surface 21 of the holder 13, and the tape 20 is also attached to the upper surface 22 of the microphone 11.

効果を得ることができる。 Therefore, by attaching the tape 20 to the contact surface Q (arrow) of the holder 13 with the living body, it is possible to prevent the microphone 11 from popping out from the fitting part 14, and also to prevent the microphone 11 from popping out from the fitting part 14, and also to prevent the microphone 11 from popping out from the fitting part 14. It is also possible to prevent the cord 12 from twisting. Furthermore, even if the tape 20 is attached, the same effect as in the above embodiment is achieved.
effect can be obtained.
