中文摘要 | 本研究設計與開發了一套具電子式高壓放電系統之電水式體外震波醫療機以提供在震波碎石術、骨疾治療、消脂及其他醫療技術所需之震波產生源。本文所設計與開發之震波醫療機是由五個子系統所組成,而此五個子系統分別為:(1)震波產生器:此設備為一橢圓反射體,負責將第一焦點所產生的震波聚焦於第二焦點;(2)雷射輔助定位系統:此系統利用光學以及幾何原理將光線投射於皮膚上以達到定位之目的;(3)自動供水系統:此系統負責提供震波傳遞所需的介質並利用電磁閥以及伺服馬達以達到自動供水之目的;(4)高壓放電系統:此系統負責提供於第一焦點利用一對電極棒間端瞬間放電進而產生震波所需之電壓;(5)自動控制系統:此系統包含供水系統以及高壓放電系統之控制。本文所研發的高壓放電系統不僅適用於電水式體外震波產生器,其亦可裝配於電磁式體外震波產生器做為其驅動能量釋放之來源。文中內容闡述所有系統之控制流程以及電路圖。此外,高壓放電系統的每個控制訊號和其時序流程亦以由示波器所擷取之訊號來證明其正確性。特別值得一提的是高壓放電系統所產生的電磁波干擾訊號可以降低99%。最後,由系統所產生之聚焦震波其波形之正壓峰值、負壓峰值、上昇時間以及下降時間和震波能量密度(強度)亦透過PVDF 壓力探針於水中完成量測。 |
英文摘要 | In this study, a therapy machine consisting of an electronic-type high-voltage system with an electrohydraulic shock wave generator was successfully developed for the purpose of noninvasive treatments such as lithotripsy, skeletovascular disorders, lipotripsy and other therapies. The designed and developed machine was divided into 5 subsystems: (1) a shock wave generator that consists of a pair of electrodes for current discharge and an ellipsoidal shock wave reflector; (2) an automatic water supply system which supplies the water as shock wave propagation medium. The water supply system uses electromagnetic valves and motor to achieve the need of the automatic water supply; (3) a laser-assisted positioning device that uses optics and a triangle geometry relation for projecting light onto a skin in order to localize a target; (4) a high-voltage discharge system which provides voltage needed by the two electrodes. The two electrodes produce shock waves at the first focus near the ellipsoidal shock wave reflector; (5) an automatic control system that includes the control of the water supply system and the high-voltage discharge device. The developed high-voltage discharge device can be used for other types of shock wave generator such as electromagnetic generators. It is noted that electromagnetic interferences associated with our developed high-voltage device have been reduced by 99%. The positive peak pressures, negative peak pressures, and shock wave intensities associated with focusing shock waves have been measured by using a PVDF membrane hydrophone (pressure sensor). |
