Abstract
医療用ポンプ用の圧力監視システムを提供する。
【解決手段】ポンプ用の圧力監視システムは、圧力監視流路46を有するポンプ10と、圧力監視流路内に配設されたチュービング34と、チュービング内の圧力を監視するためにチュービングと接触可能な圧力センサーと、ポンプドア14と、ポンプドアの内側に配設されている、ポンプドアがポンプに固定される前および固定されたときチュービングおよび圧力監視流路と係合する突出部58とを備え、突出部は、ポンプドアがポンプに固定される前および固定されたときに圧力監視流路の上側の面と接触し、それにより突出部が圧力監視流路の方へさらに移動するのを防ぎ、ポンプドアは固定手段によりポンプに固定可能であり、ポンプドアのポンプへの固定により、突出部に隣接するドアの部分が外向きに曲がり、それにより突出部を圧力監視流路の方へ付勢する。
【選択図】図4
Description
の医療用ポンプ用の圧力監視システムに関するものである。圧力監視システムは、ポンプの移動などの環境効果、またはより重要なことであるが、使用者がポンプを掴むなどのポンプに印加される外力から圧力測定を隔離する。
は、一貫した装填がなされるので、より正確な一貫した圧力読み取り値が得られる。チュービング34がすべての側部上で制約されている場合、チューブ内の圧力による膨張力は、圧力センサー50の方へより完全に向けられうる。チュービング34が側壁54と接触していない場合、チュービングは、圧力センサー50に容易に当接し、誤差の源である側壁との摩擦をなくすことができる。
部は、チュービングを圧縮して流路内に押し込み、突出部はチュービングの方への突出部の移動を停止するためポンプ表面と接触し、突出部は、チュービングの方へ付勢される。圧力監視システムは、さらに、ドアが閉じられたときに外向に曲げられそれにより突出部をチュービングの方へ付勢する突出部に隣接するドアの一部をさらに備えることができ、突出部は表面に接触するためのチュービング接触面および流路に接触しそれによりチュービングに向かう突出部の移動を停止する流路接触面を有し、突出部は第1および第2の流路接触面を有し、第1の流路接触面は流路の第1の側部と接触し、第2の流路接触面は第1の側部の反対側にある流路の第2の側部と接触し、および/または流路接触面は流路の頂部に隣接する表面と接触するか、またはこれらの組み合わせもありうる。
