The present invention relates to a peripheral physiology inspection apparatus and a peripheral auxiliary device for smart phone. The peripheral physiology inspection apparatus is connected to a smart phone with a TRRS socket for physiological inspection and includes: an inspection main body having a first physiology sensing unit a plurality of signal transmission units and a TRRS terminal for connecting to the inspection main body through the signal transmission unit. The TRRS terminal corresponds to the TRRS socket, allowing the inspection main body to be electrically connected to the smart phone, so that the smart phone can receive and analyze the physiological signals detected by the inspection main body.本發明係有關於一種智慧型手機之週邊生理檢測裝置及週邊輔助裝置,該週邊生理檢測裝置係用以連接一智慧型手機以進行生理檢測,此智慧型手機具有一TRRS插座,而此週邊生理檢測裝置包括:一檢測本體,檢測本體係包含一第一生理感應單元;複數個信號傳導單元;以及一TRRS端子,此TRRS端子係藉由信號傳導單元與檢測本體連接,且TRRS端子係對應TRRS插座,以使檢測本體電性耦接於智慧型手機,俾由檢測本體所檢測之生理信號係傳送至智慧型手機進行分析判斷。100...智慧型手機1001...TRRS插座101...檢測本體102...信號傳導單元103...TRRS端子1011...第一生理感應單元104...信號轉換介面
