図1は、本実施の形態にかかる電子血圧計(以下、血圧計)1の構成の具体例を示すブロック図である。
図3を参照して、保持部11は、その内部に空気を保持するための保持空間11Aと、エア管10または空気袋13との境界位置に配される逆止弁11Bとを含む。
<動作概要>
血圧計1での測定動作は、空気袋13を内包した測定帯(不図示)を手首や上腕などの測定部位に巻き回して空気袋13を装着した上で、測定開始が指示されると開始される。
図4は、上記動作を行なうための、血圧計1の機能構成の具体例を示すブロック図である。図4に示される各機能は、CPU40がメモリ6に記憶されるプログラムを読み出して実行することで、主にCPU40上に形成されるものであるが、少なくとも一部が図1に示された装置構成や電気回路などのハードウェア構成によって実現さあれてもよい。
上述のように、空気袋13を内包した測定帯を測定部位に巻き回した後に測定帯に圧力を加えることで、保持部11に保持された空気が逆止弁11Bを通ってエア管10または空気袋13に排気されるため、空気袋13の内圧が変化する。
図7および図8は、血圧計1での測定動作開始までの動作の流れを表わすフローチャートである。図7および図8のフローチャートに示される動作は、操作部3に含まれる図示しない電源スイッチが押下されて血圧計1に電源が投入されると開始される動作であって、CPU40がメモリ6に記憶されるプログラムを読み出して実行し、図4に示される各機能を発揮させることによって実現される。
血圧計1において以上の動作が行なわれることで、測定者は、測定帯を被測定者の測定部位に巻き付けた後に、操作部3の配された本体まで戻ることなく、測定帯を測定部位に巻き付ける動作を行なった位置にて測定開始を指示することができる。また、そのために、特別な構成を血圧計1に必要とせずに実現することができる。そのため、装置価格を抑えつつ業務効率を格段に向上させることができる。
