Description
・創傷領域に加えられる負圧がポンプの吸引によって作られるため、ポンプ内への流れがポンプを汚染し易い、又はその逆に、抗菌フィルタ等のポンプを創傷滲出物から分離するための高価で複雑な方法が要求される。
・創傷滲出物が硬質のキャニスタ中に採取されるが、それは溢れることがないように十分な大きさを有していなければならない。従って、かさばったものとなってしまい、携帯用の装置を持ち運ぶ歩行可能患者にとっては負担となる。
・慣習的な創傷排液システムは、創傷の気密シールを利用し、それは負圧を生み出して維持するのに都合が良いものであるが、特許文献1に記載されるように、創傷密封を促進するのに所望される圧力循環を生成するための圧力リリーフ弁又はブリード弁を必要とする。
・シールされた創傷被覆材又は容器は、負圧下において、接続チューブを通して滲出物の負圧源に向けた移動を促進し、チューブを閉塞させて浸出物を凝固させる場合がある。
・慣習的なシステムにおいて負圧レベルを監視し、制御するためには、真空トランスデューサ、ゲージ、又はリリーフ弁を使用する必要があり、これらは汚染に晒される吸引チューブに接続されなければならない。負圧監視又は制御装置を洗浄、消毒、又は分離することは複雑で費用がかかり、信頼性の低いものである。
限定された容積を定めるように創傷周辺をカバーによってシールする工程と、
限定された容積を真空ポンプに連通する工程と、
真空ポンプに排液を採取するための廃物容器を連結する工程と、
真空ポンプを作動させて滲出する液体を排液する工程とを有する。

- 創傷開口に負圧を作用させ、前記創傷開口から滲出する液体を排液するための真空システムであって、限定された容積を定めるように創傷周辺をシールするカバーと、当該限定された容積と流体連通する真空源と、当該真空源と流体連通する排液を採取するための廃物容器とを備え、これにより当該真空源が作動された際に排液が当該真空源に向かって流れるようになっている前記真空システムにおいて、
前記カバーが、負圧がチューブ開口部を介して前記限定された容積内に生成されるように、前記チューブ開口部を有しているチューブによって前記真空源に接続されているカバー出口を有しており、
1つ以上のブリーディング・ホールが、前記チューブの上且つ前記カバーの外側において前記カバー出口の近辺に設けられており、
これにより、負圧が作用した状態において、周辺空気が、前記1つ以上のブリーディング・ホールを介して前記チューブの前記チューブ開口部に流入し、前記滲出する液体と共に前記真空源に向かって前記チューブ開口部を通じて流れる、真空システム。 - 前記真空源が、非使い捨ての駆動ユニットに取外し可能に取付けられる使い捨て可能なポンプを含んでいる真空ポンプであって、前記カバー及び前記廃物容器は、排液及びそれと接触する空気が使い捨て可能な部品のみに接触するような形態で使い捨てができ、前記排液を当該使い捨て可能な部品と共に廃棄することが可能である前記真空ポンプである、請求項1に記載の真空システム。
- 前記ポンプユニット及び前記駆動ユニットは、簡単な手動操作によって取付け及び取外しができるものである、請求項2に記載の真空システム。
- 前記真空源が、前記限定された容積内において所定レベルの負圧が維持されるように、駆動ユニットと当該駆動ユニットを動かす制御ブロックとを備えるものであり、
当該制御ブロックが、当該所定レベルを維持するために、当該駆動ユニットの作動パラメータを感知するセンサと当該作動パラメータから当該限定された容積内の負圧レベルを導き出すための手段とを有し、当該センサは当該限定された容積と流体連通することがない、請求項1〜3のいずれか一項に記載の真空システム。 - 前記駆動ユニットが電気モータを備え、前記作動パラメータが当該モータの電流及び/又は電圧を含む、請求項4に記載の真空システム。
- 前記廃物容器が、前記排液と混合される気体を解放するように通気される、請求項1〜5のいずれか一項に記載の真空システム。
- 前記廃物容器が折畳み可能な袋である、請求項1〜6のいずれか一項に記載の真空システム。
- 前記真空ポンプが、気体及び液体及び/又はそれらの混合物を汲みだすのに適した2室隔壁ポンプである、請求項2〜7のいずれか一項に記載の真空システム。
- 歩行可能患者の装着に適合された、請求項1〜8のいずれか一項に記載の真空システム。
- 創傷開口に負圧を作用させ、前記創傷開口から滲出する液体を排液するためのカバーであって、
当該カバーが、限定された容積を定めるように創傷周辺に取付け可能であり、当該限定された容積内に負圧が生じるように、チューブ開口部を有しているチューブによって真空源に連結可能なカバー出口を有し、
1つ以上のブリーディング・ホールが、前記チューブの上且つ前記カバーの外側において前記カバー出口の近辺に設けられており、
これにより、負圧が作用した状態において、周辺空気が、前記1つ以上のブリーディング・ホールを介して前記チューブの前記チューブ開口部に流入し、前記滲出する液体と共に前記真空源に向かって前記チューブ開口部を通じて流れる、カバー。 - 前記真空源が動作していない場合に、前記周辺空気が、前記ブリーディング・ホールを介して前記カバーの外側から前記チューブ開口部に流入し、これにより前記カバー内の圧力と前記周辺空気の圧力とが均等になる、請求項10に記載のカバー。
- 前記カバー出口に連結されている前記チューブと前記真空源との間には、室が設けられており、これにより前記真空源が動作している場合に、前記カバー内の空気が前記チューブ及び前記室を通じて前記真空源に引き込まれる、請求項10又は11に記載のカバー。
