Abstract
Description
陥入爪による創傷を治療するために側爪甲縁に沿って指に装着される絆創膏構造体であって、
(i)陥入爪による創傷に密着するための創傷密着用の柔軟性表面を有する創傷密着部領域、及び
(ii)側爪甲縁を受け入れて側爪甲縁に沿って爪の長手方向にスライド可能なスライド溝を有するガイド部領域
を有し、
該絆創膏構造体は略ロッド状の形状を有し、該スライド溝は該絆創膏構造体の先端部から後端部の間の距離の少なくとも一部にわたって該絆創膏構造体の長手方向に延びており、
ただし、該絆創膏構造体を指に装着した状態で、指の根元側に位置する該構造体の端部をその先端部と定義し、指の先端側に位置する該構造体の端部をその後端部と定義し、
該絆創膏構造体を指に装着すると、該創傷密着用の柔軟性表面が陥入爪による創傷の位置までガイドされる
ことを特徴とする絆創膏構造体
が提供される。
(i)陥入爪による創傷に密着するための創傷密着用の柔軟性表面を有する創傷密着部領域、及び
(ii)側爪甲縁を受け入れて側爪甲縁に沿って爪の長手方向にスライド可能なスライド溝を有するガイド部領域
を有し、
該絆創膏構造体は略ロッド状の形状を有し、該スライド溝は該絆創膏構造体の先端部から後端部の間の距離の少なくとも一部にわたって該絆創膏構造体の長手方向に延びており、
ただし、該絆創膏構造体を指に装着した状態で、指の根元側に位置する該構造体の端部をその先端部と定義し、指の先端側に位置する該構造体の端部をその後端部と定義し、
該絆創膏構造体を指に装着すると、該創傷密着用の柔軟性表面が陥入爪による創傷の位置までガイドされる
ことを特徴とする絆創膏構造体。
ガイド部領域のための硬質体が、可撓性の低い樹脂体、可撓性の低い金属体、硬質パルプ体、ガラス体、石材体、及びセラミック体よりなる群から選ばれることを特徴とする前項2に記載の構造体。
(i)陥入爪による創傷に密着するための創傷密着用の柔軟性表面を有する創傷密着部領域、及び
(ii)側爪甲縁を受け入れて側爪甲縁に沿って爪の長手方向にスライド可能なスライド溝を有するガイド部領域
を有する。
ただし、該絆創膏構造体を指に装着した状態で、指の根元側に位置する該構造体の端部をその先端部と定義し、指の先端側に位置する該構造体の端部をその後端部と定義する。
絆創膏構造体の創傷密着部領域2の材質としてはハイドロゲル シート(日本国のコンバテック ジャパン株式会社 製の「デュオアクティブ ET」(登録商標))(膨潤前の厚み:0.7mm)を用い、ガイド部領域3の材質としてはABS樹脂を用いた。ガイド部領域3の厚み:0.5mm。(用いたハイドロゲル シートは、初期状態では膨潤しておらず、創傷への適用後に、創傷から滲出する体液で膨潤するタイプである。)創傷密着部領域2とガイド部領域3の相互の接着には、医療用の接着剤である日本国の東亞合成株式会社 製のアロンアルファA「三共」(登録商標)を用いた。絆創膏構造体の長手方向に沿って測定されるサイズは、10mmであった。絆創膏構造体の長手方向を横切る方向に沿って測定されるサイズ(取っ手1Cを含む)は、14mmであり、このうち、創傷密着部領域2の存在する部分のサイズは8mmであった。
絆創膏構造体の先端部を爪の先端側から側爪甲縁に沿って挿入し、スライド溝3Aを側爪甲縁に沿って爪の根本方向にスライドさせることにより、創傷密着部領域2の創傷密着用の柔軟性表面2Aを陥入爪による創傷の位置までガイドした。絆創膏構造体の全体が爪先端(フリーエッジ)よりも奥に達するまで押し込んだ。次に、ガイド部領域3及び取っ手1Cと爪の上側表面との間に接着剤(日本国の東亜合成株式会社製「アロンアルファ」A「三共」(登録商標))を流し込み、絆創膏構造体を爪の上側表面に接着・固定した。
上記装着操作を第1治療日に行った。第1治療日の7日後(第2治療日)に絆創膏構造体を取り外し、再度上記と同じ装着操作を行なって、絆創膏構造体を交換した。第2治療日の6日後に、患者の入浴中に絆創膏構造体が自然に外れ、その翌日(第2治療日の7日後)に本発明者が足指を観察して、完治を確認した。
第1治療日における治療処置(絆創膏構造体の装着)前の足指の写真を図14aと図14bに示す。大きな肉芽形成、発赤、腫脹、及び疼痛が認められた。歩行困難であった。
第2治療日(第1治療日の7日後)における治療処置(絆創膏構造体の交換)前の足指の写真を図16aと図16bに示す。この時点で約80%程度の治癒が認められた。疼痛は無く、歩行も正常であった。
第2治療日(第1治療日の7日後)における治療処置(絆創膏構造体の交換)後の足指の写真を図17aと図17bに示す。
第2治療日の7日後における足指の写真を図18aと図18bに示す。若干の腫脹が残る以外は完治していた。第2治療日の2〜3日後(即ち、第1治療日の9〜10日後)には完治していたものと推定される。
治療日の7日後に本発明者が足指を観察して、完治を確認した。
治療日における治療処置(絆創膏構造体の装着)前の足指の写真を図19aと図19bに示す。著しい疼痛、内出血、炎症、及び肉芽形成が認められた。歩行困難であった。
治療日における治療処置(絆創膏構造体の装着)後の足指の写真を図20aと図20bに示す。絆創膏構造体の装着直後に疼痛が消失し、歩行が改善した。
治療日の7日後に絆創膏構造体を取り外す前の足指の写真を図21aと図21bに示す。
治療日の7日後に絆創膏構造体を取り外した後の足指の写真を図22aと図22bに示す。完治していた。
治療日の7日後に本発明者が足指を観察して、ほぼ完治を確認した。
治療日における治療処置(絆創膏構造体の装着)前の足指の写真を図23aと図23bに示す。爪の欠損、著しい疼痛、内出血、炎症、腫脹、及び肉芽形成が認められた。歩行困難であった。
治療日における治療処置(絆創膏構造体の装着)後の足指の写真を図24aと図24bに示す。絆創膏構造体の装着直後に疼痛が消失し、歩行が改善した。
治療日の7日後に絆創膏構造体を取り外す前の足指の写真を図25aと図25bに示す。
治療日の7日後に絆創膏構造体を取り外した後の足指の写真を図26aと図26bに示す。ほぼ完治していた。炎症所見がほぼ消失し、肉芽部分の上皮化がほぼ完成していた。後は数日以内に自然治癒により完治することが明らかであった。
治療開始から約2か月後の時点での治癒の程度は約50%程度であった。まだ歩行困難であった。器具の最初の装着(治療開始)から約1週間後には疼痛が若干緩和したが、疼痛は消失せず、約2か月後の時点でも疼痛が認められた。
