支架材料與結構的疲勞測試

我們的挑戰

傳統的支架和支架移植物測試(標準如 ASTM F2477)涉及到對完整裝置預先指定週期數模擬血流脈動的支配。即使該裝置未破壞,僅表示能進行一個單純通過標準的測試。工業界正在進行的工作是開發更先進的方法,在體外對心血管植入裝置特性進行表徵和評估,提供有關何時和在什麼條件下會發生破壞的資訊。

為了使試片有具代表性的樣本以進行評估,並降低整體測試時間,多重樣本必須在單一系統上進行測試。

我們的解決方案

ElectroPuls® E3000 全電式測試儀多重試片夾具的開發是為了協助心血管植入物製造商評估鎳鈦(鎳鈦合金)和不銹鋼支架材料、結構長期的疲勞特性。

每個試片站都設有疲勞型荷重元,精確的定位調整及對於進行材料或結構測試的特有夾具。整個測試站均浸泡在溫度控制浴裡測試體外試片。此測試是由 WaveMatrix2 動態測試軟體所控制,其中包含了許多幫助用戶運行測試的功能。這些功能包括流體浴的整體溫度控制、每個荷重元讀數的即時顯示,以及測定每個試片破壞力量的趨勢監控。
