Abstract
Description
本出願は、2017年9月10日に出願された米国仮特許出願第62/556,479号に対する優先権を主張するものであり、この米国仮特許出願は、参照によりその全体が本明細書に組み込まれ、本開示の一部をなす。
医療のほぼすべての領域が、特に治療中にかかる情報がリアルタイムで収集される場合、治療される組織、器官、またはシステムの状態に関する改善された情報から恩恵を受ける可能性がある。多くのタイプの治療は、センサデータ収集の使用なしに依然として日常的に実施されるが、代わりに、こうした治療は、定量的センサデータではなく、介護者またはその他の限定的手段による目視検査に依存する。例えば、被覆材および/または陰圧創傷療法を介した創傷治療の場合、データ収集は一般的に介護者による目視検査に限定され、また多くの場合、下にある創傷組織は包帯またはその他の視覚障害物によって遮られうる。損傷を受けていない無傷の皮膚でさえ、潰瘍につながりうる血管損傷または深部組織損傷など、裸眼には見えない潜在的な損傷を有しうる。創傷治療と同様に、ギプスまたはその他の覆いで肢の固定化を必要とする整形外科処置中も、限定された情報のみしか下層組織について収集されない。骨プレートなどの内部組織修復の場合、継続的な直接センサ駆動データ収集は実施されない。さらに、筋骨格機能を保持するために使用される留め具および/またはスリーブは、下にある筋肉の機能または肢の動きを監視しない。直接処置の外には、患者パラメータを監視する能力を追加することによって、ベッドおよび毛布などの一般的な病室のアイテムが改善され得る。
本明細書に開示されるいくつかの実施形態は、ヒトのまたは動物の体に対する創傷療法に関する。そのため、本明細書における創傷へのいかなる言及も、ヒトまたは動物の体上の創傷を指すことができ、本明細書における体へのいかなる言及も、ヒトまたは動物の体を指し得る。開示技術実施形態は、生理学的組織または生体組織への損傷の防止または最小化、または例えば、陰圧源および創傷被覆材構成要素および装置などを含む、減圧を伴うまたは伴わない損傷した組織(例えば、本明細書で説明した創傷など)の治療に関連し得る。創傷オーバーレイおよびパッキング材料、または、存在する場合には内層を備える、装置および構成要素は、時に総称して本明細書では被覆材と呼ばれる。いくつかの実施形態では、創傷被覆材は、減圧せずに利用されるように提供され得る。
いくつかの実施形態では、このような創傷の治療は、陰圧創傷療法を使用して行うことができ、減圧または陰圧を創傷に印加して、創傷の治癒を容易にすること、および促進することができる。本明細書に開示される創傷被覆材および方法は、身体の他の部分に適用されてもよく、創傷の治療に必ずしも限定されないことも、理解されるであろう。
図1は、創傷空洞110の内部に配置された創傷充填材130を備え、創傷空洞が創傷カバー120によって封止される、負圧または減圧創傷治療(またはTNP)システム100の実施形態を例示する。創傷カバー120と組み合わされた創傷充填材130は、創傷被覆材として言及され得る。単一または複数の内腔管または導管140は、創傷カバー120と、減圧圧力を供給するように構成されるポンプアセンブリ150とを接続する。創傷カバー120は、創傷空洞110に流体連通することができる。図1に例示される実施形態のような、本明細書に開示されるシステム実施形態のいずれかにおいて、ポンプアセンブリは、キャニスタレスポンプアセンブリ(滲出液が、創傷被覆材で回収されるか、または回収のための管140を介して別の場所に移されることを意味する)とすることができる。しかし、本明細書で開示されるいくつかのポンプアセンブリの実施形態は、キャニスタを含むまたは支持するように構成され得る。追加的に、本明細書で開示されるいくつかのシステムの実施形態において、いくつかのポンプアセンブリの実施形態は、被覆材に取付けられ、もしくは被覆材によって支持され、または被覆材に隣接することができる。
図2は、創傷被覆材200の断面図を例示し、創傷被覆材は、図1の創傷カバー120および創傷充填材130に類似し得るか、または同じであり得、図1の導管140に類似し得る流体コネクタ204を有する。創傷被覆材200は、創傷接触層222に取り付けられた頂部層もしくはカバー層、または裏当て層220を含むことができ、これらは、内部空間またはチャンバを画定するように、一緒に結合または封止することができる。この内部空間またはチャンバは、陰圧を分配または伝達し、創傷の滲出液および創傷から除去した他の流体を貯蔵するように、ならびに他の機能を行うように適合させることができる、追加的な構造を含むことができる。このような構造の例としては、本明細書に記載される透過層226および吸収層221が挙げられる。さらに、センサアレイの一部であり得る1つ以上のセンサ250は、図示する創傷接触層222などの創傷被覆材200上またはその中へ組み込まれてもよい。
図2の創傷被覆材200などの創傷被覆材は、図2の1つ以上のセンサ250などのいくつかのセンサまたはセンサを組み込むことができる。いくつかのセンサ技術は、創傷被覆材または総合創傷被覆材装置の一部を形成する1つ以上の構成要素において使用することができる。例えば、1つ以上のセンサは、図2の創傷接触層222などの創傷接触層またはシートの上または中に組み込むことができ、創傷接触層は、創傷と接触して配置することができ、また、流体が通過することを可能にし、一方で、創傷内の組織にほとんどまたは全く損傷を生じさせない。センサ統合型創傷接触層またはシートは、シリコーンなどの可撓性材料で作製することができ、抗菌物質または他の治療剤を組み込むことができる。センサ統合型創傷接触層またはシートは、湿組織または乾組織に接着する接着剤を組み込むことができる。さらに他の実装形態では、1つ以上のセンサを、追加的または代替的に、吸収層またはスペーサ層などの、創傷被覆材の他の構成要素内に組み込むこと、または封止することができる。
いくつかの実施形態では、センサ、接続部などの電気または電子部品は、創傷、皮膚、または創傷および皮膚の両方の中または上に配置することができる1つ以上の創傷被覆材構成要素の上に配置もしくは位置付けること、またはその中に組み込むことができる。例えば、1つ以上の電子部品は、図2の創傷接触層222の下表面224などの、創傷に面する創傷接触層側に位置付けることができる。創傷接触層は、創傷に適合するか、または覆うために可撓性、弾性、または伸縮性、もしくは、実質的に可撓性、弾性、または伸縮性であってもよい。例えば、創傷接触層は、様々なフルオロポリマー(FEP)およびコポリマー、または別の好適な材料と共に、ポリウレタン、熱可塑性ポリウレタン(TPU)、シリコーン、ポリカーボネート、ポリエチレン、ポリイミド、ポリアミド、ポリエステル、ポリエチレンテレフタラート(PET)、ポリブチレンテレフタレート(PBT)、ポリエチレンナフタレート(PEN)、ポリエーテルイミド(PEI)のうちの1つ以上といった、伸縮性または実質的に伸縮性のある材料から作製され得る。いくつかの実例では、1つ以上の電子部品は、あるいは、またはさらに、透過層、吸収性層、バッキング層、または創傷被覆材のその他任意の好適な層のうちの、いずれか1つ以上に位置決めまたは埋め込まれ得る。
いくつかの実施形態によれば、1つ以上のコーティングまたは1つ以上の接着領域を、1つ以上の構成要素またはシート430の領域に適用することができる。いくつかの実施形態では、コーティングは、電子接続部410または電子機器モジュール402などの、基材によって支持されるシート430または構成要素の1つ以上を封止またはコーティングするように構成された共形コーティングとすることができる。コーティングは、生体適合性を提供すること、電子部品が流体と接触することから遮断または保護すること、などができる。コーティングは、好適なポリマー、1072−M UV、光、または熱硬化性もしくは硬化接着剤、Optimax接着剤(NovaChem Optimax8002−LVなど)などの接着剤、パリレン(パリレンCなど)、シリコン、エポキシ、ウレタン、アクリル化ウレタン、シリコーン、または別の好適な生体適合性かつ伸縮性の材料、のうちの1つ以上とすることができる。
創傷被覆材および創傷療法システムに関して本明細書に記載されるものが挙げられるがそれらに限定されない、可撓性回路基板を含むコーティングされた電子部品は、構成要素の適切な製造およびコーティングについて検査される。いくつかの実施形態では、回路基板は、伸展性であり得る。いくつかの実施形態では、可撓性および/または伸展性回路基板は、本明細書に記載される可撓性回路基板の使用に類似して使用することができる。コーティング材料および/または接着剤は、透明な場合があり、コーティングまたは接着剤の欠陥または不十分なカバレージを識別することが困難な場合がある。加えて、可撓性回路基板上の構成要素の配置を検査および確認することが有用であり得る。
本明細書に提供される閾値、制限、期間などの任意の値は、絶対的であることを意図せず、したがって近似であり得る。さらに、本明細書で提供される任意の閾値、限界値、期間などは、自動的にまたはユーザによって、固定されるかまたは変えられうる。さらに、本明細書で使用される場合、参照値に関連した、超える、超、未満などの相対的な程度を表す用語は、参照値と等しい場合も包含することが意図される。例えば、正の参照値を超えることは、参照値以上であることを包含することができる。その上、本明細書で使用される場合、参照値に関連した、超える、超、未満などの相対的な程度を表す用語は、参照値に関連した、下にある、未満、超などの開示された関係とは逆のものも包含することが意図される。また、種々のプロセスのブロックは、ある値が特定の閾値に達するかまたは達しないかを判定することに関して説明されうるが、ブロックは、例えば、ある値が(i)閾値未満であるかもしくは閾値を超えているか、または(ii)閾値を満たすかもしくは満たしていないかに関しても同様に解釈されうる。
