であるという欠点があつた。 By the way, the sound collecting cuff is made of a flexible material such as rubber and is formed into an elongated bag shape, and has a substantially rectangular cross section as shown in the figure, but there is a limit to the thickness of both side walls. Its height is also limited, so
The sound collection cuff for Korotkoff sound detection is compressed by the pressure applied by the ischemic cuff, blocking the air passage, and disturbance noise caused by rubbing of the upper and lower walls of the sound collection cuff makes it difficult to accurately detect Korotkoff sounds. The drawback was that it was difficult to detect.

れる。 3 to 5 show an embodiment of the present invention. In the figures, numeral 1 denotes an elongated bag-shaped sound collecting cuff made of a flexible material such as rubber;
A, side walls 1b, 1b, and top wall 1c form a substantially square cross section, and edge stands 2, 2 extend from both ends of the bottom wall 1a, respectively. 3 is an air conduit protruding from the middle part of the sound collecting cuff 1, and 4 is a reinforcing frame to prevent pressure from being compressed by the air pressure inside the ischemic cuff, which is made by winding a steel wire into a coil shape. The reinforcing frame 4 is formed into a substantially elliptical shape that is elongated in the direction, and the reinforcing frame 4 is fixed to the outer surfaces of both side walls 1b, 1b, respectively.
A blood ischemic cuff (not shown) is wrapped around the upper arm with a cuff, and the bottom wall 1a of the sound collecting cuff 1 attached to the inside of the blood ischemic cuff is brought into contact with the surface of the upper arm.

検知される。 Next, how to use it will be explained. First, as is well known, by wrapping an ischemic cuff (not shown) around the upper arm with a cuff, the bottom wall 1a of the sound collecting cuff 1 attached to the inside of the ischemic cuff is applied to the surface of the upper arm. After that, air is forced into the inner space of the ischemic cuff, and the outer peripheral surface of the upper arm is compressed with air pressure, thereby compressing the blood vessel. Then, the air inside the ischemic cuff is gradually removed. The Korotkoff sound generated during the process of deflating the air in the ischemic cuff is detected by a microphone (not shown) installed in the sound collecting cuff 1.

圧漬されるということもない。 By the way, as mentioned above, the sound collecting cuff 1 is made of a flexible material, and the reinforcing frame 4 that prevents pressure from being compressed in the vertical direction is fixed to the outer surface of both side walls 1b, 1b. The bottom wall 1a of the sound collecting cuff 1 can be reliably brought into contact with the upper arm surface, and the sound collecting cuff 1 will not be submerged by the air pressurized into the ischemic cuff.
なお、上記実施例における補強枠４は、両側壁

である。 Although the reinforcing frame 4 in the above embodiment is fixed along the outer surfaces of both side walls 1b, 1b, it goes without saying that the reinforcing frame according to the present invention is not limited to this. Although the reinforcing frame 4 according to the above embodiment has a substantially elliptical cross-sectional shape, it goes without saying that the cross-sectional shape is not limited to this.
次に、第６図乃至第８図は本発明の異なる実施

面に同一符号を付すことにより説明を省略する。 Next, FIGS. 6 to 8 show different embodiments of the present invention, and the difference from the above embodiment is that the reinforcing frame 4 is embedded in both side walls 1b and 1b, respectively. Since this embodiment is similar to the embodiment described above, the same reference numerals are given to the drawings and the explanation thereof will be omitted.
かかる実施例においては、補強枠４が外部に露
出しないため、上腕に巻装するに際して邪魔にな

て、採音効果はより確実になる。(Effects of the Invention) As described above, the present invention provides reinforcing frames to prevent pressure in the vertical direction on both side walls of the elongated bag-like sound collecting cuff made of a flexible material, so that the sound collecting cuff is not compressed in the ischemic cuff. Even if the pressure of compressing the upper arm increases by injecting air, the sound collecting cuff will not be compressed vertically.
Therefore, the sound pickup effect of the microphone inside the sound collection cuff,
In other words, this has the effect of maintaining high sensitivity. In addition, as in the above embodiment, in the case where the steel wire is wound with a substantially elliptical cross section and is arranged along both side walls, it is possible to prevent pressure in the vertical direction as well as to have sufficient flexibility. Therefore, it can be easily curved and placed along the outer circumferential surface of the upper arm, and therefore the sound recording effect becomes more reliable.
