在目前的復健領域當中,弁鄔妏q刺激器在中樞神經系統損傷患者的復健應用上扮演著舉足輕重的腳色。本研究承襲前人的研究成果,致力開發出一套完整的弁鄔妏q刺激系統,以提供使用者最為淺顯易懂的操作及最便利的使用。
本系統主要的改良部分可以分為兩大方向,包含硬體與軟體。在硬體方面,本研究針對原有的輸出端類比電路作修改,以B類輸出級配合變壓器,取代原本的電流鏡電路,使得刺激器在必v的消耗上能得到更高的使用效率,並且在各個輸出通道間能夠達到隔離的效果,更加提高了使用上的安全準則。在軟體部分,本系統提供一套親切的人機介面,包含了刺激元素設定模組、刺激療程設計模組及四個通道刺激電流即時顯示視窗,提供臨床治療人員一個非常便利的使用介面,在設計及調整患者的復健療程上能夠更快速且順手。此外,在刺激器的可攜性上也做了諸多改良,包括體積與重量的大幅減少、小鍵盤及LCD模組的內建等,均提高了本刺激器系統對於使用者的便利性。
本研究與臺大醫院醫工部合作,通過醫療儀器電性安全評估測試,並以正常人為受試者做了手部抓握的弁鄔夆囮@測試。不論是在使用的方便性與訓練的效果上,均達到不錯的成績。
