Abstract
Description
この発明は、以下の圧力、すなわち、ソケットとライナとの間の負圧、ライナと残留手足の皮膚との間の負圧、ライナとソケットとの間の正圧、ライナと皮膚との間の正圧を測定するために使用できる。
予備試験
9人の片側膝下手足切断者がこの研究に参加した。この研究には血管切断者は含まれていない。この研究は歩行しながら行った測定を比較したため、すべての被験者は全面支持型ソケットを定期的に使用し、毎日歩いた。
義肢システム この研究を行うときは、各被験者に対して一つの義肢システムを使用した。それは、末端に1方向逆止弁を備えた従来の全面支持型ソケットを有している。手足切断者はまずウレタンのライナを装着する。ウレタンライナの上にはナイロンのシースが被っている。次に脚を試験ソケットの中へ挿入する。ウレタンのサスペンションスリーブをソケットの上半分と下腿の上に巻き付けて、脚に対するサスペンションを形成する。この構造は、ライナとソケットとの間にあるスペースを-69kPaの真空に引く、1方向逆止弁へ連結された真空ポンプ(Gast)を追加した、真空付加条件にも使用することができる。ソケットをパイロン、及びソリッドアンクルクッションヒール(Solid Ankle Cushion Heel(SACH))の足へ取り付けてシステムを完成する。
義肢フィッティング
被験者は彼らが試験を行う日以前の3ヶ月以内に鋳型をとった。これは、各被験者に対して適切にフィットするカスタムメードのライナ及びソケットを製造するために行った。鋳型取りと試験との間のこの時間は、手足の容積が長期の変化をあまりしない状態でのライナの器具化と校正を可能にする。
被験者は試験のまえにできるだけ容積の損失を小さくするために朝早く研究室へ報告を行った。到着すると、登録された義肢技術者が義足を動的に位置合わせする。各被験者は試験を続けるまえに新しいシステムについて快適な状態になる。ライナを装着すると、皮膚とライナとの間に残った空気はいっさいシステムから排除される。いったんこれを実行すると、フラットワイヤのまわりにワイヤがライナを出るところでワセリンを塗布し、ワイヤに沿った空気の流れを最小限に抑える。
3つの2要因繰り返し測定ANOVAs(α=0.05)を使用して、スタンスフェーズのときに二つのソケット条件の間で5つの力検出用抵抗に対するインパルス値、平均圧力、及び0.1秒ピーク圧力に違いがあるかを決定することができる。3つの1要因ANOVAs(α=0.05)を実行して、スウィングフェーズのときに空気圧力センサのインパルス値、平均圧力、及び0.1秒ピークに二つの条件の間で違いがあるかを決定することができる。
ソケット壁の中に埋め込まれた適当なセンサによって温度を測定することができる。湿度は湿度計などの装置によって測定することができる。
センサを設置したら、装着員は次にディスプレイあるいは例えば可聴アラームなどのアラームに対して限界値(例えば上限及び下限)を設定する。ディスプレイ及びアラームデバイスはデジタル出力及び/あるいは可聴アラームを使用していることが好ましい。そうしたデバイスの概略が図2に示されている。
