A position detecting device for first aid apparatus includes a carrying unit, a lateral shaft, a plurality of elastic members and a displacement detector. Wherein, the carrying unit includes a carrying plate and a lateral plate. The carrying plate is applied to load the first aid apparatus, and the lateral plate is disposed on the carrying plate for blocking the first aid apparatus when the first aid apparatus is slid on the carrying plate, so that the first aid apparatus is positioned at the lateral portion of the lateral plate. The lateral shaft is located at the bottom plane of the carrying unit and disposed between the centre and a lateral side thereof. The elastic members are located at the bottom plane of the carrying unit. The displacement detector detects the amounts of the deformation of the elastic members.一種緊急救護器材之位置偵測裝置,包括承載單元、側軸、複數彈性件及偵測位移感知器,其中,承載單元包含承載板與側擋板,承載板用以承載緊急救護器材,側擋板位於承載板上,於緊急救護器材在承載板上滑移時止擋緊急救護器材,以定位於緊急救護器材於側擋板之側邊;側軸位於承載單元之底面,設置於承載板之中央處與一側邊之間的位置處;複數彈性件位於承載單元之底面;偵測位移感知器偵測複數彈性件之受壓變形量。100‧‧‧位置偵測裝置11‧‧‧承載單元111‧‧‧承載板111a‧‧‧中央111b‧‧‧第一側邊111c‧‧‧底面111d‧‧‧第二側邊112‧‧‧側擋板112a‧‧‧側邊114‧‧‧底板115‧‧‧固定板116‧‧‧斜擋板12‧‧‧側軸121‧‧‧樞接結構13‧‧‧彈性件14‧‧‧偵測位移感知器141‧‧‧碰觸開關件9‧‧‧緊急救護器材
