の検出が難しいという問題があつた。 Conventional blood pressure measurement cuffs generally consist of an ischemic cuff (an air bladder for ischemia) and a sound-collecting cuff (an air bladder for detecting Korotkoff sounds), but the sound-collecting cuff is made of a flexible rubber material, etc. Even if it was made of rubber, it was made of a long thin rectangular rubber bag with a flat surface, so it was flexible to some bending, but the way the cuff was wrapped could be deflected, or the outside When pressed too hard, the sound collection cuff partially bends, blocking the air passage, making it difficult to accurately detect Korotkoff sounds. In addition, the sound collecting surface of the sound collecting cuff also has irregular wrinkles and does not come into close contact with the upper arm of the human body, making it difficult to accurately detect Korotkoff sounds.
本発明は叙上の欠点に鑑みて成したもので、そ

提供せんとするものである。 SUMMARY OF THE INVENTION An object of the present invention is to provide a cuff for blood pressure measurement that accurately detects Korotkoff sounds by bringing the sound collecting surface of the cuff (an air bag for detecting Korotkoff sounds) into close contact with the upper arm of a human body.
以下、本発明の一実施例を図面を参考にして説

である。 An embodiment of the present invention will be described below with reference to the drawings. 1 to 6 are diagrams showing one embodiment of the present invention. In the figure, reference numeral 1 denotes a sound collecting cuff (an air bag for detecting Korotkoff sounds), which is made of an elastic material such as rubber, and has grooves 4 formed in a mesh shape on its sound collecting surface 2. 5 is a protrusion formed by the groove 4;

に突出している。 Reference numeral 7 denotes an ischemic cuff, which is equipped so as to form a sound collecting surface of the sound collecting cuff 1 on a part of its upper arm abutting surface.Therefore, the membrane back surface 3 of the sound collecting cuff 1 is connected to the inner cavity of the ischemic cuff 7. It stands out.

５図及び第６図に示す。 Further, a magic fastener 10 is provided on the outer circumferential surface of the ischemic cuff 7 and a wrapping band 9 protruding from one end of the ischemic cuff 7, to maintain the state in which the ischemic cuff 7 is wrapped around the upper arm. The wrapped state is shown in FIGS. 5 and 6.

れて径小になる。 Here, air is introduced into the inner spaces of the sound collecting cuff 1 and the blood ischemic cuff 7 by the air injector 11 to inflate them. Since the upper arm 8 of the human body is compressed by the ischemic cuff 7 and embedded inside, the blood vessel 8a is also compressed and becomes smaller in diameter.

After pressurizing to a specified pressure, if you gradually exhaust the air,
Korotkoff sounds (cardiac pulse sounds) are produced by the blood flow passing through the compressed blood vessels 8a when the air pressure in the ischemic cuff 7 is reduced below a certain level, and are picked up by the microphone inside the cuff 1. can detect sound.
集音カフ１の集音面２には溝を縦横に網目状に
形成しているから、上腕の外周面によく順応して
当接し、不規則なしわが起るのを防止できる。 Since the sound collecting surface 2 of the sound collecting cuff 1 is formed with grooves in the form of a mesh in the vertical and horizontal directions, the sound collecting surface 2 of the sound collecting cuff 1 conforms well to the outer circumferential surface of the upper arm and abuts against it, thereby preventing the occurrence of irregular wrinkles.
なお、集音カフ１は第７図に示すように集音面
２のみでなく、皮膜背面３にも溝４が形成されて

る。 Note that, as shown in FIG. 7, the sound collecting cuff 1 may have grooves 4 formed not only on the sound collecting surface 2 but also on the back surface 3 of the membrane. Even though it is an elongated sound collecting cuff, it can be brought into close contact with the outer surface of the columnar human upper arm 8.

凸条５が形成されていてもよいのである。 Furthermore, the shape of the groove 4 is V-shaped in cross section, and the protrusion 5
The groove 4 is not limited to a trapezoidal shape, and as shown in FIG. 8, the groove 4 may form a protrusion 5 having a substantially semicircular cross section.

ることができる効果がある。 As described above, the cuff band for blood pressure measurement of the present invention includes a blood pressure cuff to be wrapped around the upper arm of a human body, and a sound collecting cuff with a built-in microphone, the sound collecting surface of which forms a part of the upper arm abutting surface of the blood pressure cuff. In the cuff band for blood pressure measurement equipped with the sound-collecting cuff, since a plurality of mesh-like grooves are uniformly formed in the membrane of the sound-collecting cuff, there will be no irregular wrinkles when it is wrapped around the upper arm of the human body. It is easy to bring the sound collecting surface into close contact with the outer circumferential surface of the cuff, and when the sound collecting surface is in close contact with the outer circumferential surface, the Korotkoff sound of the upper arm of the human body is transmitted to the entire sound collecting surface through the hollow part of the groove, and is therefore accommodated in the inner hollow part of the sound collecting cuff. With this microphone, Korotkoff sounds can be recorded effectively and the sensitivity of blood pressure measurement can be increased.

る効果がある。 In addition, as described in claim 2, if mesh-like grooves are uniformly formed on the back surface of the membrane of the sound collecting cuff that faces the sound collecting surface, sound can be picked up from the upper arm contact surface of the sound collecting cuff. The Korotkoff sounds resonating in the internal space of the ischemic cuff can also be collected from the back of the membrane of the sound collecting cuff, which has the effect of making the detection of Korotkoff sounds more effective.
