　図１に示す本実施形態に係る血圧計１０は、被測定者の腕に巻き付け可能に構成された腕帯本体１６を有する腕帯部１２と、腕帯部１２が着脱可能な血圧計本体１４とを備える。医療機関において、腕帯部１２は、被測定者の腕周りの寸法の大きさに応じて、適切なサイズのものを血圧計本体１４に接続できるように腕帯本体１６の長さが異なる複数のサイズバリエーションが用意され、必要に応じて血圧計本体１４から腕帯部１２が取り外され、適切なサイズの腕帯部１２が接続される。また、腕帯部１２は、消耗品であり、所定期間使用した後には廃棄される。その際、古い腕帯部１２が血圧計本体１４から取り外され、新しい腕帯部１２が血圧計本体１４に接続される。血圧計１０は、適切な腕帯部１２が血圧計本体１４に接続された状態で使用されることで、血圧計１０による測定結果の信頼性が高まる。 A sphygmomanometer 10 according to the present embodiment shown in FIG. 1 includes an armband part 12 having an armband body 16 configured to be wound around the arm of a measurement subject, and a sphygmomanometer body 14 to which the armband part 12 is detachable. With. In a medical institution, the armband unit 12 has a plurality of armband bodies 16 having different lengths so that an appropriate size can be connected to the sphygmomanometer body 14 according to the size of the measurement subject's arm. Size variations are prepared, the armband portion 12 is removed from the sphygmomanometer body 14 as necessary, and the armband portion 12 of an appropriate size is connected. The armband portion 12 is a consumable item and is discarded after being used for a predetermined period. At that time, the old armband portion 12 is removed from the sphygmomanometer body 14, and the new armband portion 12 is connected to the sphygmomanometer body 14. The sphygmomanometer 10 is used in a state in which an appropriate armband portion 12 is connected to the sphygmomanometer main body 14, thereby increasing the reliability of the measurement result obtained by the sphygmomanometer 10.
　腕帯部１２は、帯状の腕帯本体１６と、腕帯本体１６に一端部が接続されたチューブ部１８と、チューブ部１８の他端部に接続されたコネクタ部材２０とを備える。腕帯本体１６は、長方形状のカフカバー２２と、カフカバー２２内に配置及び固定された阻血用空気袋２４ａ（第１空気袋）及び検出用空気袋２４ｂ（第２空気袋）とを有する。カフカバー２２は、外布２２ａと内布２２ｂとからなり、内布２２ｂの外周縁部と外布２２ａの外周縁部とが例えば縫製により互いに固定されることで袋状に形成されている。 The armband portion 12 includes a belt-like armband body 16, a tube portion 18 having one end connected to the armband body 16, and a connector member 20 connected to the other end of the tube portion 18. The armband body 16 includes a rectangular cuff cover 22, and a blood-insufficiency air bag 24 a (first air bag) and a detection air bag 24 b (second air bag) disposed and fixed in the cuff cover 22. The cuff cover 22 includes an outer cloth 22a and an inner cloth 22b, and is formed in a bag shape by fixing the outer peripheral edge portion of the inner cloth 22b and the outer peripheral edge portion of the outer cloth 22a to each other by, for example, sewing.
　阻血用空気袋２４ａ及び検出用空気袋２４ｂは、外布２２ａと内布２２ｂとの間に配置されている。阻血用空気袋２４ａは、被測定者の上腕を阻血するための空気袋である。阻血用空気袋２４ａは、血圧計本体１４から空気を供給することにより上腕の動脈を加圧して阻血する。 The ischemic air bladder 24a and the detection air bladder 24b are disposed between the outer cloth 22a and the inner cloth 22b. The ischemic air bladder 24a is an air bladder for isolating the upper arm of the measurement subject. The air bag 24a for ischemia pressurizes the artery of the upper arm by supplying air from the sphygmomanometer body 14 to block blood.
　検出用空気袋２４ｂは、脈波を検出するための空気袋であり、収容できる空気容量が阻血用空気袋２４ａよりも小さい。検出用空気袋２４ｂは、カフカバー２２内で阻血用空気袋２４ａに重なる位置に配置されている。脈波は、阻血用空気袋２４ａの内圧を最高血圧以上に上げて血管を一旦圧閉した後、内圧を徐々に下げて内圧が最高血圧以下になり、血管が開き始めると急激に大きくなり平均血圧付近で最大になる。その後圧力を下げると脈波の振幅は小さくなっていき、最低血圧以下になると振幅カーブに変曲点が現れる。検出用空気袋２４ｂは複数設けられてもよい。 The detection air bag 24b is an air bag for detecting a pulse wave, and the air capacity which can be accommodated is smaller than the air bag 24a for ischemia. The detection air bladder 24b is disposed in the cuff cover 22 at a position overlapping the ischemic air bladder 24a. The pulse wave is increased by increasing the internal pressure of the air bag 24a for ischemia above the maximum blood pressure and once closing the blood vessel. Maximum near blood pressure. After that, when the pressure is lowered, the amplitude of the pulse wave becomes smaller, and when the pressure becomes lower than the minimum blood pressure, an inflection point appears in the amplitude curve. A plurality of detection air bags 24b may be provided.
　チューブ部１８は、第１エアチューブ１８ａ及び第２エアチューブ１８ｂを有する。第１エアチューブ１８ａと第２エアチューブ１８ｂとは並列して設けられている。第１エアチューブ１８ａは、一端部が阻血用空気袋２４ａに接続されている。第２エアチューブ１８ｂは、一端部が検出用空気袋２４ｂに接続されている。第１エアチューブ１８ａ及び第２エアチューブ１８ｂは、例えばエラストマ材等により構成されたフレキシブルなチューブである。 The tube portion 18 includes a first air tube 18a and a second air tube 18b. The first air tube 18a and the second air tube 18b are provided in parallel. One end of the first air tube 18a is connected to the air bag 24a for ischemia. One end of the second air tube 18b is connected to the detection air bag 24b. The 1st air tube 18a and the 2nd air tube 18b are flexible tubes comprised, for example with the elastomer material etc.
　第１エアチューブ１８ａは、阻血用空気袋２４ａに対する空気の給排気に用いられる。第２エアチューブ１８ｂは、検出用空気袋２４ｂに対する空気の給排気に用いられるチューブであり、第１エアチューブ１８ａよりも小径に形成されている。第１エアチューブ１８ａ及び第２エアチューブ１８ｂの各他端部は、コネクタ部材２０に接続（固定）されている。チューブ部１８とコネクタ部材２０との接続強度は、コネクタ部材２０と後述するコネクタ装着部４２との接続強度よりも大きい。これにより、コネクタ部材２０がコネクタ装着部４２に接続された状態でチューブ部１８を誤って無理矢理引っ張った場合でも、チューブ部１８がコネクタ部材２０から分離することが防止される。 The first air tube 18a is used to supply and exhaust air to and from the air bag 24a for ischemia. The second air tube 18b is a tube used for supplying and exhausting air to and from the detection air bag 24b, and has a smaller diameter than the first air tube 18a. The other end portions of the first air tube 18 a and the second air tube 18 b are connected (fixed) to the connector member 20. The connection strength between the tube portion 18 and the connector member 20 is higher than the connection strength between the connector member 20 and a connector mounting portion 42 described later. This prevents the tube portion 18 from being separated from the connector member 20 even when the tube portion 18 is accidentally pulled by force while the connector member 20 is connected to the connector mounting portion 42.
　図１及び図２に示すように、腕帯部１２のコネクタ部材２０は、互いに外径が同一の第１接続筒部２８ａ及び第２接続筒部２８ｂと、第１接続筒部２８ａ及び第２接続筒部２８ｂを共通に支持する支持部３０とを有する。第１接続筒部２８ａは、オスコネクタを構成しており、血圧計本体１４に設けられた後述するメスコネクタを構成する第１接続穴部５６ａ（図６参照）に挿入（嵌合）可能である。第１接続筒部２８ａの突出端には開口２８ａ１が設けられている。第２接続筒部２８ｂは、オスコネクタを構成しており、血圧計本体１４に設けられた後述するメスコネクタを構成する第２接続穴部５６ｂ（図６参照）に挿入（嵌合）可能である。第２接続筒部２８ｂの突出端には開口２８ｂ１が設けられている。 As shown in FIGS. 1 and 2, the connector member 20 of the armband portion 12 includes a first connection cylinder portion 28 a and a second connection cylinder portion 28 b, and a first connection cylinder portion 28 a and a second connection portion having the same outer diameter.
