The propose work was designed the method and the devices to quantitatively measure patient before and after sedative injecting respectively. The method including a data processing unit to connect with the measurement data base a measurement unit to measure the physiological signal a display module connected with data processing unit to display and play the physiological signal. The comparisons before and after sedative injecting respectively, the clinical technician can decide whether the patient can recovery and go home or not by proposed method and devices. Instead of the subjective decision of clinical technician, we believe the objective assessments applied by propose technique will reduce the mistakes of subjective assessment and improve the medical safety and quality.本發明係提供一種服用鎮靜劑患者前後行為量化評估方法及裝置,係包含:一資料處理單元,係與一個人測試資料庫連接;一測量模組,係與資料處理單元連接,係用於測量患者生理情況;及一顯示播放模組,係與資料處理單元連接,係用於顯示及播放檢查患者後之生理數據及生理情況。藉由資料處理單元交叉比對患者第一次及第二測試值,使資料處理單元判別比對值是否達到離院允許值,再進一步顯示或播放是否可離院之訊息,相信醫院技術人員利用所提供之量化方法與設置必然能更客觀降低人為主觀之誤判,進而大幅提升醫療之安全性及品質。
