Description
本出願は、その全体が参照により本明細書に組み込まれる、2016年7月8日に出願された米国仮特許出願第62/360,233号の利益を主張する。
本開示の一態様では、ハウジングおよびコネクタを備える接続デバイスが本明細書に提供され、コネクタは、NPWT中にキャニスタおよび/または吸収性創傷被覆材等の流体保持源に接続するように構成され得る。いくつかの実施形態では、異なる構成を有する2つ以上のコネクタが、制御ユニットの同じ汎用領域に接続するように構成されている1つの汎用部分を備える。非限定的な例として、制御ユニットは、陰圧源を収容する。場合によっては、コネクタの汎用領域は、空気出口継手および任意選択でセンサ出口継手を備える。場合によっては、制御ユニットは、コネクタの汎用領域と嵌合するように構成されている領域を備え、制御ユニットは、空気出口継手と接続するように構成されている第1の接続箇所とセンサ出口継手と接続するように構成されている任意選択の第2の接続箇所とを備える。いくつかの実施形態では、コネクタの汎用領域は、空気出口継手およびセンサ出口継手を備え、継手は、約4mm~約80mm離間している。コネクタは、デバイスの嵌合面の幅の両端に載置されるか、またはそのサイズが許す限り互いに近接して載置されることができるため、場合によっては、デバイスおよびコネクタの寸法を考慮して、より幅広く離すか、または互いにより近接して載置してもよい。場合によっては、コネクタは、一方の接続が他方の接続内に位置して便宜的な形態を提供するように互いに同心になるように配置することができる。
本開示の別の態様では、キャニスタとともにNPWTで使用するためのコネクタが本明細書に提供され、コネクタは、流体経路によって流体出口継手に接続された流体入口継手と、空気経路によって空気出口継手に接続された空気入口継手とを備え、流体出口継手は、流体出口継手および空気入口継手をキャニスタに接合すると、空気入口継手と流体連通するように構成されている。いくつかの実施形態では、流体出口継手は、キャニスタの流体受容継手と接続するように構成されている。場合によっては、コネクタの流体出口継手またはキャニスタの流体受容継手は、コネクタとキャニスタとの間に密閉接続を提供するように構成されている密閉部材を備える。いくつかの実施形態では、空気入口継手は、キャニスタの空気放出継手と接続するように構成されている。場合によっては、コネクタの空気入口継手またはキャニスタの流体受容継手は、コネクタとキャニスタとの間に密閉接続を提供するように構成されている密閉部材を備える。いくつかの実施形態では、流体入口継手は、例えば流体供給管を介して移行被覆材と接続するように構成されている。いくつかの実施形態では、流体入口継手は、例えば流体供給管を介して流体保持被覆材と接続するように構成されている。いくつかの実施形態では、空気出口継手を陰圧源の接続箇所へ接続すると、空気出口継手は、陰圧源と流体連通するように構成されている。場合によっては、コネクタの空気出口部分または陰圧源の接続箇所は、コネクタと陰圧源との間に密閉接続を提供するように構成されている密閉部材を備える。密閉部材の非限定的な例は、Oリングまたはコンプライアント材料のガスケット等の他の密閉部材またはTPE表面等の成形シールである。陰圧源の非限定的な例は、回転DCブラシ付モータによって駆動されるダイヤフラムポンプである。代替として、ブラシレスDCモータを使用してダイヤフラムポンプを駆動するか、またはボイスコイルアクチュエータ等のリニアアクチュエータがダイヤフラムを直接駆動する。いくつかの実施形態では、コネクタは、センサ経路によってセンサ出口継手に接続されたセンサ入口継手をさらに備える。
本開示の別の態様では、流体保持被覆材とともにキャニスタなしのNPWTで使用するためのコネクタが本明細書に提供され、コネクタは、空気経路によって空気出口継手気に接続された空気入口継手を備え、空気入口継手は、流体保持被覆材と接続するように構成され、空気出口継手は、陰圧源から印加された陰圧が流体保持被覆材によって受容されるように、陰圧源と接続するように構成されている。いくつかの実施形態では、コネクタは、センサ経路によってセンサ出口継手に接続されたセンサ入口継手をさらに備える。場合によっては、センサ入口継手は、流体保持被覆材と接続するように構成されている。場合によっては、センサ出口継手は、圧力センサと接続するように構成されている。いくつかの実施形態では、圧力センサおよび陰圧源は、制御ユニットに収容されている。
本開示の一態様では、本明細書に記載のコネクタおよび接続デバイスを使用してNPWT中に流体保持源を交換するための方法が本明細書に提供される。流体保持源を交換するための例示的方法は、概して、(a)制御ユニットおよび第1の流体保持源の両方に接続された第1のコネクタを備えるNPWTシステムを提供することと、(b)第1のコネクタを制御ユニットおよび第1の流体保持源からいずれかの順序で切り離すことと、(c)第2のコネクタを第2の流体保持源および制御ユニットにいずれかの順序で接続することと、を含む。いくつかの実施形態では、制御ユニットは、陰圧源、陰圧源と流体連通する第1の接続箇所、センサ、およびセンサと流体連通する第2の接続箇所を備える。いくつかの実施形態では、第1のコネクタは、制御ユニットの第1の接続箇所および第2の接続箇所に接続される。いくつかの実施形態では、第1のコネクタおよび第2のコネクタは各々、空気経路によって接続された空気出口継手および空気入口継手と、センサ経路によって接続されたセンサ出口継手およびセンサ入口継手とを備える。いくつかの実施形態では、制御ユニットの第1の接続箇所は、ステップ(a)で第1のコネクタの空気出口継手に、かつステップ(c)で第2のコネクタの空気出口継手に接続される。いくつかの実施形態では、制御ユニットの第2の接続箇所は、ステップ(a)で第1のコネクタのセンサ出口継手に、かつステップ(c)で第2のコネクタのセンサ出口継手に接続される。いくつかの実施形態では、第1の流体保持源は、ステップ(a)で第1のコネクタの空気入口継手に接続され、第2の流体保持源は、ステップ(c)で第2のコネクタの空気入口継手に接続される。いくつかの実施形態では、液体が第1のコネクタ内に位置する場合、第1のコネクタが第1の流体保持源から切り離されると、液体が第1のコネクタ内に保持される。
NPWTシステムとともに使用するための制御ユニットを、吸収被覆材または移行被覆材およびキャニスタのいずれかを使用するシステムにおいて陰圧を供給するように製造した。制御ユニットは、第1のコネクタを介して吸収被覆材と、第2のコネクタを介して移行被覆材およびキャニスタとに接続するように構成されている。制御ユニットは、第1のコネクタおよび第2のコネクタの両方の空気出口継手と接続するように適合された第1の接続箇所を備える。第1の接続箇所は、デバイス内に収容されたダイヤフラムポンプと連通する。制御ユニットの概略図は、図3の320または図6の620によって表される。
実施例1の接続デバイスは、電源を備える。電源は、デバイスのコネクタの種類に依存する場合もある。吸収性被覆材とともに使用するための第1のコネクタについて、電源は、移行被覆材およびキャニスタとともに使用するための第2のコネクタよりも少ない電力を必要とするが、より多くの量の滲出液が経時的に収集されてもよい。したがって、接続デバイスは、その使用に応じて調整可能である。さらに、電源は、任意選択で取り外し可能および/または交換可能である。
患者は、NPWT中にキャニスタを用いて滲出液を収集する必要がある滲出性創傷を呈する。移行被覆材は、創傷部位の周囲に密閉される。移行被覆材は、第2のコネクタを有する実施例1の接続デバイスを介してキャニスタおよび制御ユニットに接続される。大気圧未満の約80~125mmHgの陰圧が、創傷部位に印加される。滲出液は、移行被覆材の開口部を第2のコネクタの流体入口継手に接続する流体管を介して創傷部位から第2のコネクタに引き込まれる。滲出液は、第2のコネクタを通ってキャニスタ内に通過する。キャニスタは、制御ユニットから第2のコネクタを切り離すことによって任意選択で交換され、切り離すと、システム内の陰圧が、第2のコネクタを収容するデバイスからの滲出液の漏れを防止する。追加の被覆材、キャニスタ、および第2のコネクタが供給され、NPWTは続行する。
