- 所定の試験用流体を循環させる流体回路により構成され、当該流体回路の途中に医療用試験対象物を設置し、前記試験用流体に人体の血流状態を模擬した流れを与えて前記医療用試験対象物の耐久性試験を行うための装置であって、
前記試験用流体が流れる流路と、当該流路の途中に設けられて前記試験対象物が設置されるとともに、屈曲変形、ねじれ変形及び/又は伸縮変形が可能に構成された設置部と、前記流路内を循環する前記試験用流体を拍動流の状態にする流れ生成手段と、前記設置部の入口側における前記試験用流体の圧力及び/又は流量を検出する流れ状態検出手段と、前記設置部に外的負荷を加えて屈曲変形、ねじれ変形及び/又は伸縮変形させるように動作する動作手段と、前記流れ状態検出手段で検出された圧力及び/又は流量の状態に応じて、前記動作手段の動作を制御する制御手段とを備え、
前記制御手段では、前記設置部の入口側における前記試験用流体の圧力及び/又は流量の変化に基づいて、前記設置部の動作を同期させるように前記動作手段を制御することを特徴とする医療用試験対象物の耐久性試験装置。 - 前記制御手段では、前記試験用流体の圧力及び/又は流量の周期的な変化に同期して前記屈曲変形、ねじれ変形及び/又は伸縮変形がなされるように、前記動作手段の動作を複数パターンで制御することを特徴とする請求項1記載の医療用試験対象物の耐久性試験装置。
- 前記制御手段では、前記試験用流体の圧力又は流量が所定値に達したタイミングで、前記設置部の変形が開始するように、前記動作手段の動作を制御することを特徴とする請求項2記載の医療用試験対象物の耐久性試験装置。
- 前記制御手段では、前記試験用流体の圧力又は流量が極大になるタイミングと前記設置部が最大に変形するタイミングとを合わせるように、前記動作手段の動作を制御することを特徴とする請求項2記載の医療用試験対象物の耐久性試験装置。
- 所定の試験用流体を循環させる流路の途中に設けられた設置部に医療用試験対象物を設置し、前記試験用流体に人体の血流状態を模擬した流れを与えて前記試験対象物の耐久性試験を行うための方法であって、
前記試験用流体を拍動流の状態にして前記流路を循環させた上で、前記試験用流体の圧力及び/又は流量を周期的に変化させ、前記設置部の入口側における前記試験用流体の圧力及び/又は流量の変化に基づいて、前記設置部に周期的な外的負荷を与えることで、前記試験用流体の流れ状態に同期するように、前記設置部の屈曲、ねじれ、及び/又は伸縮を繰り返し行いながら前記耐久性試験を行うことを特徴とする医療用試験対象物の耐久性試験方法。
