Description
次の要約は、読み手が理解するためのより詳細な議論を紹介するために提供される。要約は、請求項を限定または範囲を決定することを意図しない。
多様な器具または工程が、それぞれの請求項に係る発明の態様の例を提供するために以下に記述される。下記に記述する態様は、いずれの請求項に係る発明を限定するものでなく、請求項に係る発明はいずれも、以下に記述されていない工程または器具を含んでもよい。請求項に係る発明は、以下に記述されているいずれか1つの器具もしくは工程の特徴の全てを有する器具または工程、または、以下に記述されている器具の多くのもしくは全てに共通する特徴に限定されない。以下に記述された器具または工程が、この特許出願の発行によって与えられるいかなる独占権の態様でもないことは可能である。以下に記述される器具または工程において開示されるいかなる発明であって、この特許出願の発行によって独占権が、与えられないものは、他の保護手段、例えば、連続する特許出願の対象になってもよく、出願人、発明者または所有者は、この書類における公表によって、発明のいずれも放棄する、棄権する、または公共の用に供することを意図しない。
ここで使用されるように、「エーテル化したヒドロキシエチルセルロース」なる用語は、繰り返し単位の少なくともいくつかの置換基の少なくとも1つが、1以上のエーテル基を含むヒドロキシエチルセルロースを指す。例えば、ヒドロキシエチルセルロース は、一般に次の化学式によって表されてもよい(他の化学式も可能であるが)。
混合は、空気の混入を避けるためにゆっくりと随意に遂行されてもよい。
例1
抗微生物医療用ジェルは、上記で述べたように、次の構成物で調製した。
ゲル化剤 : 2.6 重量% エーテル化したヒドロキシエチルセルロース (ShinEtsu Tylose(登録商標) HS 100000 YP2)
抗微生物剤: 0.2 重量% 塩化ベンザルコニウム (Stepanquat(登録商標)50 NF);
溶媒: 3.2重量%プロパンジオール (Dupont Zemea(商標))
および、
水:94重量%
異なるゲル化剤の種々の水溶液の濁度を測定した。試験は、溶液において0.1重量%の塩化ベンザルコニウムあり、およびなしの両方で行われた。アクアソニック・クリアー・ウルトラサウンド・ジェル(Aquasonic Clear Ultrasound gel)のコントロールサンプルがコントロールとして使用された。結果は、下記に表1において表されている。濁度は、Hack Model 2100 Laboratory Turbidimeterを用いて測定される。
種々の溶媒を有する種々のジェルの濁度を測定した。すべてのジェルは、前述のように調製した。すべてのジェルは、ゲル化剤としてShinEtsu Tylose(登録商標) HS 100000YP2 HECのエーテル化したヒドロキシエチルセルロースで作成した。すべてのジェルは抗微生物剤として塩化ベンザルコニウムで作成した。濁度は、Hack Model 2100 Laboratory Turbidimeterを使用して測定された。結果は下記表2において表されている。
種々の溶媒を有する種々のジェルの耐乾燥性を測定した。すべてのジェルは前述のように調製した。すべてのジェルは、ゲル化剤としてShinEtsu Tylose(登録商標) HS 100000YP2 HEC のエーテル化したヒドロキシエチルセルロースで作成した。すべてのジェルは抗微生物剤として塩化ベンザルコニウムを用いて作成した。耐乾燥性は、ガラスのスライドの上のサンプルの既知の量を量り、そして、量られたスライドをセ氏38度でインキュベーター・オーブン・セット(incubator oven set)へ置くことによって測定した。スライドは2時間間隔で取り出されそして量を量られた。結果は、下記表3において表されている。
種々の溶媒の拡散する能力を測定した。抗微生物剤を含む溶媒は、抗微生物剤のない溶媒と同様に、試験した。塩化ベンザルコニウムを、抗微生物剤として使用した。拡散能力は、スタンダードNo. 1 フィルターペーパー(Standard No. 1 filter paper)へ液体の一滴を落とすことおよび、それぞれの滴の直径を種々の時間期間で測定することによって測定された。結果は、下記表3において示され、およびそれぞれのサンプルにつき3つの試験後に得られた平均結果を示す。
抗微生物医療用ジェルの3サンプルは上記で述べるように、次の構成物で調製した。
ゲル化剤: 2.6重量% エーテル化したヒドロキシエチルセルロース (ShinEtsu Tylose (登録商標)HS 100000 YP2)
抗微生物剤: 0.2重量% 塩化ベンザルコニウム (Stepanquat(登録商標) 50 NF)
溶媒: 3.2重量% プロパンジオール (Dupont Zemea(商標))
および
水: 94重量%
次の観察は、上記例1〜6に述べるように調製されたジェルに関して行った。
・ ジェルは、仮の可塑性(シェアーシニング)(shear thinning)を示し、搾り出し容器からただちに調剤可能であることが観察された。
・ ジェルは、医療用ジェルとしての使用に適する粘性をもつように見えた。
・ ジェルは、医療用ジェルとしての使用のために適する滑らかさであるように見えた。
・ ジェルは、最小の空気の閉じ込め(air entrapment)を示すように見えた。これは、エーテル化したヒドロキシエチルセルロースのゆっくりした可溶性のためだと考えられ、それはゲルから空気を放出するための時間を与える。
