Abstract
Description
簡単に要約すると、本明細書に開示される実施形態は、一般的に、血液フラッシュ検出システムおよびその方法に関する。実施形態は、管腔を画定し、医療ラインと流体連通するニードルおよびニードルハブなどのインジケータデバイスを含む。ニードルハブは、管腔内に配置される電極を備えた、RFIDタグなどのマーカを含む。例えば血液のような流体の流れが管腔に入ると、電極間の電気的接続が架橋され(bridged)、回路が完成し、マーカがアクティブ状態となる(activating)。次に、マーカは問い合わせ信号に応答し、応答信号を提供することができる。応答信号は、検出デバイスによって検出および解釈され、ユーザが挿入部位またはデバイスを直接観察することなく脈管構造にアクセスされたことをユーザに示す。本明細書に記載される実施形態は、コンダクタンスに基づくデジタル血液フラッシュデバイスおよびその使用方法のさらなる態様をさらに記載する。
