【発明の詳細な説明】 l 発明の名称 湿潤性、親水性、軟性及び酸素透過性の共重合体組成物2 技術分野 本発明は新規な共重合体組成物に関し、そして更に増大した酸素透過性、軟性、 親水性、濃混潤性、耐脱水性、耐付着性の且つ安定なコンタクト・レンズ、眼帯 或いは火傷又は怪我の包帯に対する人工皮膚のための共重合体に関する。[Detailed description of the invention] l Name of invention Wettability, hydrophilicity, flexibility and oxygen permeability copolymer composition 2 Technical field The present invention relates to novel copolymer compositions and further provides increased oxygen permeability, softness, Hydrophilic, highly miscible, dehydration resistant, adhesion resistant and stable contact lenses and eye patches Or to copolymers for artificial skin for burn or injury dressings.
医学のいくつかの分野における重合体物質に対して、基本的な必要条件は、それ が親水性、軟性、体液湿潤性、耐付着性及び安定であることである。従来法は多 くの異なる重合体材料の、例えばコンタクト・レンズ、眼帯、人工膜例えば外科 および火傷用の包帯、人工肺器官の膜におけるような医学の分野における使用法 を教示している。そのような重合体はその特別な医用のためのある望ましい性質 を有するけれど、それはその宵月性を減する他の望ましくない特性も持っている 。For polymeric substances in some fields of medicine, a basic requirement is that It is hydrophilic, soft, wettable with body fluids, adhesion resistant, and stable. Conventional methods of many different polymeric materials, e.g. contact lenses, eye patches, artificial membranes e.g. surgical and uses in the field of medicine, such as in burn dressings, membranes of artificial lung organs. is taught. Such polymers have certain desirable properties for their special medical uses. , but it also has other undesirable properties that reduce its ephemeral nature. .
コンタクト・レンズの分野において、コンタクト・レンズを、特に最も望ましい 延長されt;着装使用に関して成功ならしめるために、多くの必要とされる特徴 がある。コンタクト・レンズの歴史の各時代に開発された材料の長所及び欠点を 要約するために、望ましいコンタクト・レンズの最も必要とされる特徴の各を多 数選定し、以下に列挙する;1、酸素透過性: 2、軟性; 3、親木性: 4、安定性; 5、長期間の機能的(体液又は涙)湿潤性;6、耐脱水性;及び 7、耐付着性。In the field of contact lenses, contact lenses are especially the most desirable Extended; many required features for successful wearable use. There is. We will look at the advantages and disadvantages of materials developed during each period in the history of contact lenses. To summarize, we have listed each of the most needed characteristics of a desirable contact lens. Selected numbers are listed below; 1. Oxygen permeability: 2. Softness; 3. Tree parentage: 4. Stability; 5. Long-term functional (body fluid or tear) wettability; 6. Dehydration resistance; and 7. Adhesion resistance.
コンタクト・レンズ用のプラスチック材料の開発は長い道のりであった。最も初 期には、硬質のプラスチック材料、ポリメタクリル酸メチル(PMMA)が使用 された。一般にこのノ\−ド型レンズは上記列挙の4及び6の良好な特徴を提供 するが、特徴L2.3.5及び7については大きな欠点を有している。後のヒド ロゲルレンズ、即ちポリメタクリル酸2−ヒドロキシエチル(ポリHEMA)は 、一般に2.3.4.5.6及び7の良好な特徴を提供するから普及したものの 、依然として上記の特徴lの酸素透過性に欠点を有した。角膜への酸素の不十分 な供給は角膜の深刻な損傷に至り、例えば角膜の潰瘍、感染病及び濃厚化をもた らす。斯くして最近の患者は、基本的には2つの主な種類のHGPレンズ材料、 即ちアクリルシリコーン及びアクリルフルオロシリコーンから作られたハード型 気体透過性レンズ(HGP)に看目しはじめた。一般にHGPレンズは1.4及 び6の曵好な特徴を提供するが、依然として2.3.5及び7の貧弱な特徴を有 している。この欠点の結果として、角膜の摩耗、角膜のひずみ及び不快さという 多くの事例が起こる。従ってレンズ使用者は今や上述の望ましい特徴のすべてを 提供しえるソフト型気体透過性(SGP)レンズをもつことに期待を寄せている 。The development of plastic materials for contact lenses has been a long journey. the first During the period, a hard plastic material, polymethyl methacrylate (PMMA), was used. It was done. In general, this node lens provides good features 4 and 6 listed above. However, features L2.3.5 and 7 have major drawbacks. later hide Rogel lenses, namely poly 2-hydroxyethyl methacrylate (polyHEMA), are , although popular because it generally offers good features of 2.3.4.5.6 and 7. However, it still had the drawback of the above-mentioned feature 1 in terms of oxygen permeability. Insufficient oxygen to the cornea Negative feeding can lead to severe damage to the cornea, including corneal ulcers, infections and thickening. Ras. Thus, patients these days basically have two main types of HGP lens materials: i.e. hard molds made from acrylic silicone and acrylic fluorosilicone I started looking at gas permeable lenses (HGP). Generally, HGP lenses are 1.4 or higher. and 6, but still have the poor characteristics of 2.3.5 and 7. are doing. This drawback results in corneal abrasion, corneal distortion and discomfort. Many cases occur. Lens users can therefore now enjoy all of the desirable features mentioned above. We are looking forward to having a soft gas permeable (SGP) lens that we can provide. .
SGPレンズのいくつかの発明は、例えばチャン(Chang)の米国特許第4 .182.822号及び第4,343.927号;日中の米国特許第4゜139 .513号、及びレボニー7(LeBoeuf)の米国特許第4.246.38 9号に教示されている。これらの特許の材料から作られるレンズは高酸素透過性 、軟性及び親水性という良好な特徴を提供するが、それらは上記5.6及び/又 は6の特徴に対する比較的貧弱な品質を克服しえていない。Some inventions of SGP lenses include, for example, Chang U.S. Pat. .. 182.822 and 4,343.927; Japanese-Chinese U.S. Patent No. 4.139 .. No. 513, and U.S. Pat. No. 4.246.38 to LeBoeuf. No. 9 teaches. Lenses made from these patented materials have high oxygen permeability , offer good characteristics of softness and hydrophilicity, but they are has not been able to overcome the relatively poor quality of the 6 features.
チャンの特許に記述される材料は高酸素透過性、軟性及び親水性である。しかし 驚くことに本発明者は、正に高親水性であるこの材料が長期間のフンタクト・レ ンズの着用に対して十分に良好でないことを発見した。これから使ったレンズは 非常に軟かく、親水性であるが、驚くことに長期間の機能的(涙)湿潤性が比較 的貧弱である。このレンズはある日常的な着用に優れているけれど、それは延長 された着用に適当でない。The materials described in the Chang patent are highly oxygen permeable, flexible and hydrophilic. but Surprisingly, the inventors have discovered that this highly hydrophilic material has long-term durability. I found that the lenses were not good enough for wearing. The lens I will be using from now on is Very soft and hydrophilic, but surprisingly long-term functional (tear) wettability Poor quality. This lens is excellent for certain everyday wear, but it is Not suitable for wearing.
国中又はレポユーフの特許に記述されている材料は同様の欠点を有しよう。The materials described in the National or Lepoeuf patents would have similar drawbacks.
明らかなことであるが、上述のすべての望ましい特徴を有し且つ更に技術状態を 新しい時代に高めるような共重合体を提供することの突破口をもつことは、視覚 の矯正を必要とする人間にとって非常に望ましく、また有用である。この結果患 者はコンタクト・レンズの利点を享受し、その欠点に悩まされなくなるであろう 、そのような共重合体の探索において、過去12年間ものすごい努力が払われ、 今や本発明者は新規な共重合体系を発見するに至った。Obviously, it has all the desirable features mentioned above and also has the state of the art. In a new era, having a breakthrough in providing copolymers that enhance visual It is highly desirable and useful for humans in need of correction. As a result, will enjoy the benefits of contact lenses and be less bothered by their drawbacks. Tremendous efforts have been made over the past 12 years in the search for such copolymers. The inventors have now discovered a new copolymer system.

First, each component was added to 0.2% t-butylperoxyvinyl alcohol according to the composition. Placed in an inert plastic tube with barreto. The composition is then purged with nitrogen. Deoxidized for 10 minutes.
次いでプラスチック管を45℃の水浴中に4時間入れ、次いで95℃の炉中に4 時装置いた。次いで透明な棒をボタン型に切断し、高真空下、120℃で6時間 後処理硬化させた。ボタンを徐々に冷却した。この共重合体から作りI;レンズ は透明でありI;。このレンズの酸素透過性(DK単位)は、含水量38%でD K単位約8のポリHEMA及び1以下のPMMAハード型レンズと比較して、約 60 (cm’/秒/ Ozmj!/mj!X+nmHg)であった。このレン ズはPMMAレンズの約0.5%と比べて約4%の水を吸収することができた。The plastic tube was then placed in a 45°C water bath for 4 hours and then placed in a 95°C oven for 4 hours. There was a time device. The transparent rod was then cut into button shapes and heated at 120°C for 6 hours under high vacuum. Post-processed and hardened. The button was gradually cooled.

生理学的食塩水中で十分水和した後の、上記共重合体から作ったレンズめBUT は人間の目での試験において約2分であった。しかし最近の過去の技術、即ち米 国特許第4,343.927号に記述されている如きNNDMA20 (1量) %、TMPT15%及びMPTS65%の共重合体から作ったレンズのBUTは 完全に水和した後で約0.5分であった。本発明のBUTの、過去の技術に優る 実質的な増大、即ち本実施例での約400%の増大は、コンタクト・レンズの延 長され!2着用に対して非常に望ましい。両レンズは類似の含水量又は親水性を 有するが、濃混潤性又はBUTは劇的に異なった。斯くして本実施例は、レンズ 又は共重合体の体液又は濃混潤性が材料の親水性に依存するだけでないというこ とも例示する。Lenses made from the above copolymer after thorough hydration in physiological saline BUT was approximately 2 minutes in human eye testing. However, the technology of the recent past, i.e. NNDMA20 (1 quantity) as described in National Patent No. 4,343.927 %, the BUT of a lens made from a copolymer of 15% TMPT and 65% MPTS is It took about 0.5 minutes after complete hydration. BUT of the present invention is superior to past technologies The substantial increase, approximately 400% in this example, is the increase in contact lens extension. Lengthened! Highly desirable for two wears. Both lenses have similar water content or hydrophilicity However, the thick miscibility or BUT was dramatically different.
