Description
(1.技術分野)
本開示は、陰圧創傷療法システムに関し、より具体的には、フィルター膜を有するキャニスター上面を含む流体収集キャニスターと、同じものを含む陰圧創傷療法システムとに関する。
吸引療法または真空療法としても公知の陰圧療法は、創傷を治療および治癒させる際に用いられてきた。開いた創傷を陰圧(例えば、減少された圧力または大気の常態値以下の圧力)を、創傷を覆う限局性レザバーに適用することによって治療することは、創傷範囲における血液循環を増やすことと、肉芽組織の形成を刺激することと、健康な組織の創傷に対する転移を促すこととによって、創傷を閉じるのを助けるということが分かっている。陰圧療法は、また、細菌が宿る傾向があり得る滲出物のような創傷流体を創傷から抜くことによって細菌増加を阻止し得る。したがって、陰圧療法は、その防腐効果および組織再生成効果に対する治癒様式として適用され得る。この技術は、慢性創傷および潰瘍ならびに治癒耐性の創傷および潰瘍を含むさまざまな創傷状態を治療することに対して効果的であると分かっており、術後創傷ケアのような他の目的に対しても用いられる。
本開示は、流体を収集するチャンバーと、チャンバーを覆って配置されたキャニスター上面とを含む流体収集キャニスターに関する。キャニスター上面は、チャンバーの中へ対面する底面を含み、底面は、底面上に配置された第一のリブおよび第二のリブと、第一のリブおよび第二のリブに据え付けられたフィルター膜と、チャンバーおよびチャンバーの外部の圧力供給源に連絡する第一のポートと、チャンバーおよびチャンバーの外部のセンサーに連絡する第二のポートとを含む。第一のポートは、第一の範囲に流体連絡しており、第一の範囲は、キャニスター上面のフィルター膜、第一のリブおよび第二のリブならびに底面によって境を接している。第二のポートは、第二の範囲に流体連絡しており、第二の範囲は、キャニスター上面のフィルター膜、第二のリブおよび底面によって境を接している。
本開示のさまざまな実施形態は、創傷流体を収集するチャンバーと、チャンバーを覆って配置されたキャニスター上面とを有する収集キャニスターを含む陰圧創傷療法システム(または装置)を提供する。本開示の陰圧創傷療法システムの実施形態は、一般的に、さまざまな治療様式に従った創傷の治癒を容易にするために、陰圧を創傷に適用する際の使用に対して適切である。本開示の陰圧創傷療法システムの実施形態は、全体的に可搬であり、ユーザが療法期間中に完全に動き回り得るように、ユーザによって着用または搬送され得る。本開示の陰圧創傷療法装置およびその構成要素の実施形態は、全体的に再利用可能であり得るか、または所定の期間の使用の後、全体的に使い捨てであり得るか、または個別(構成要素のうちのいくつかは、続く療法適用のために再利用される)に使い捨てであり得る。本開示の収集キャニスターの実施形態は、真空供給源からの吸引を可能にし、キャニスター真空レベルの監視を可能にする制御ユニットにインターフェースで接続する。
