| description | To provide a system for detecting falling of a catheter or a needle in vascular access.SOLUTION: A system of the present invention includes: first and second lines for fluid-connecting first and second catheters or a needle to an inlet and an outlet of a pump respectively; a first connector for connecting the first line to the first catheter or the needle, and a second connector for connecting the second line to the second catheter or the needle, each connector having an electrode; an electronic circuit connected to the electrode of the first connector and the second connector electrically, which measures electric impedance of fluid between the first connector and the second connector through a conductive path; and a controller configured to receive an electric impedance value sampled from the electronic circuit and process it as a signal.SELECTED DRAWING: Figure 1
【課題】血管アクセスでのカテーテルまたは針の脱落を検出するためのシステムを提供すること。【解決手段】システムは、第１および第２のカテーテルまたは針をポンプの入口および出口にそれぞれ流体接続する第１および第２のラインと、第１のラインを第１のカテーテルまたは針に接続する第１のコネクタと、第２のラインを第２のカテーテルまたは針に接続する第２のコネクタと、各コネクタが電極を有することと、第１のコネクタおよび第２のコネクタの電極と電気的に接続され、かつ第１のコネクタと第２のコネクタとの間の流体の電気インピーダンスを導電経路を介して測定するように構成された電子回路と、電子回路からサンプリングされた電気インピーダンス値を受信し、それを信号として処理するように構成されたコントローラと、を含む。【選択図】 図１ |
