Claims (13)

  1. 圧力をモニタするために患者の体内中に挿入可能なマルチルーメン型カテーテルであって、前記カテーテルは、
    前記カテーテルの遠位部分のところに設けられた拡張型外側バルーンを有し、前記外側バルーンは、第1の外壁を有し、
    前記外側バルーン内に位置決めされた拡張型内側バルーンを有し、前記内側バルーンは、第2の外壁を有し、
    前記内側バルーンと連通する第1のルーメンを有し、前記内側バルーンと前記第1のルーメンは、膀胱内の圧力をモニタするためにガス充填チャンバを形成し、前記外側バルーンは、前記内側バルーンの円周方向面積よりも大きい円周方向面積を有し、前記膀胱内で前記拡張後の外側バルーンの前記第1の外壁に及ぼされた圧力に応答して、前記外側バルーンは、変形し、そして圧力を前記拡張後の内側バルーンの前記第2の外壁に及ぼして前記内側バルーンを変形させると共に前記内側バルーン内および前記第1のルーメン内の前記ガスを圧縮し、それにより精密測定をもたらし、
    流体を前記膀胱から取り出すよう前記膀胱と連通した第2のルーメンを有し、
    膀胱内圧力が、前記拡張後外側バルーンによって変形された前記拡張後内側バルーンの変形によって引き起こされるガスの圧縮に基づいて測定される、カテーテル。
  2. 前記ガス充填チャンバは、前記膀胱内の圧力をモニタし、それにより前記患者の腹部内の圧力をモニタする、請求項1記載のカテーテル。
  3. 前記ガス充填チャンバと連通したセンサが、前記膀胱中への水の注入を必要としないで、前記カテーテルの挿入全体を通じて平均圧力を連続的に測定する、請求項1または2記載のカテーテル。
  4. 前記第2のルーメンは、前記内側および前記外側バルーンの近位側に位置する側部開口部を有する、請求項1〜のうちいずれか一に記載のカテーテル。
  5. 前記カテーテルは、追加のルーメンおよび中核体温を測定するよう前記追加のルーメン内に位置決めされた温度センサを有する、請求項1〜のうちいずれか一に記載のカテーテル。
  6. 前記外側バルーンは、前記膀胱の壁の平均圧力の計算のために多数の基準個所を提供するよう多数の接触領域のところで前記膀胱壁と係合可能な周囲、および前記外側バルーンをインフレートさせるよう前記外側バルーンと連通した第3のルーメンを有する、請求項1〜のうちいずれか一に記載のカテーテル。
  7. ハブ内に収容された圧力センサをさらに含み、前記カテーテルの第1のポートへの前記ハブの連結により、自動的に空気を前記内側バルーン中に送り進めて前記内側バルーンを拡張させる、請求項1〜のうちいずれか一に記載のカテーテル。
  8. 前記カテーテルは、追加のルーメンおよび安定化バルーンをさらに有し、前記追加のルーメンは、前記安定化バルーンをインフレートさせて前記カテーテルの位置を安定化するために前記安定化バルーンと連通し、前記安定化バルーンは、前記外側バルーンの近位側に位置決めされている、請求項1〜のうちいずれか一に記載のカテーテル。
  9. 細長い部材が、前記ハブから遠位方向に延びており、前記第1のポートは、弁を有し、前記細長い部材は、前記ハブが前記カテーテルの前記第1のポートに連結されると、前記弁を通って挿入可能である、請求項記載のカテーテル。
  10. 前記カテーテルは、中核体温を測定する温度センサを有し、ワイヤが前記温度センサから別のルーメンを通りかつ前記カテーテルの外側で、前記カテーテルに連結された前記ハブ中に延びており、前記ハブの前記カテーテルへの連結により、自動的に電気的に前記温度センサを電気モニタケーブルに接続する、請求項のうちいずれか一に記載のカテーテル。
  11. 前記第2のルーメンは、前記第1のルーメンと独立している、請求項1〜10のうちいずれか一記載のカテーテル。
  12. 前記外側バルーンをインフレートさせるための第2の開口部を有する第3のルーメンをさらに有し、前記第3のルーメンは、前記第1のルーメンおよび前記第2のルーメンと独立している、請求項1〜11のうちいずれか一記載のカテーテル。
  13. 前記第1のルーメンは、前記ハブが前記第1のルーメンに連結されているときに、外気に空気抜けされていない、請求項7記載のカテーテル。
