The present invention relates to a multi anesthesia depth signal measuring device, comprising: a consciousness signal measuring module, a sympathovagal activity signal measuring module, a stress pain signal measuring module, and an optimizing unit. This multi anesthesia depth signal measuring device is used to simultaneously measure an electroencephalogram (EEG), an electrocardiography (ECG) and a pulse oximetry (SpO2) from a surgical patient for providing three physiological indicators of anesthesia depth for doctors and medical professionals. Thus, the doctors and medical professionals can precisely predominate the patient’s clinical state, therefore the patient would get the best anesthetic care, such that the medical incidents and disputes can be effectively reduced.本創作係關於一種多維麻醉深度信號擷取裝置,係主要包括:一意識清晰度信號擷取模組、一自主神經活性信號擷取模組、一壓力疼痛信號擷取模組、以及優化單元;其中,本創作之多維麻醉深度信號擷取裝置係可同時擷取術中病患之腦波(EEG)、心電圖(ECG)及血氧濃度(SpO2),提供醫師與醫護人員在手術中同時監視病患之麻醉深度之三種生理指標變化(包含意識層次、自主神經反應及疼痛反應),以幫助醫師與醫護人員能更精確在臨床上判斷病人的狀態,可確保病患獲得最佳的麻醉照護,並減少醫療事故與糾紛。1‧‧‧多維麻醉深度信號擷取裝置11‧‧‧意識清晰度信號擷取模組12‧‧‧自主神經活性信號擷取模組13‧‧‧壓力疼痛信號擷取模組111‧‧‧腦電信號擷取單元121‧‧‧心電信號擷取單元131‧‧‧血氧信號擷取單元20‧‧‧信號處理單元112‧‧‧腦電信號分析單元122‧‧‧心電信號分析單元132‧‧‧血氧信號分析單元113‧‧‧意識指標單元123‧‧‧自主神經指標單元133‧‧‧壓力疼痛指標單元30‧‧‧優化單元
