This invention discloses an assistant positioning device for first aid, comprising a fixed frame, a telescopic frame, a first limiting unit and a second limiting unit. The fixed frame is fixedly arranged on a fixed surface. The telescopic frame is vertically and telescopically connected with the fixed frame and is provided with a crosspiece located at the top end. The crosspiece is provided with a first end part and a second end part which are heterochiral. The first limiting unit is slidably arranged at the first end part of the crosspiece. The second limiting unit is arranged at the second end part of the crosspiece and is matched up with the first limiting unit to define a limiting space capable of limiting a user. By using the first limiting unit and the second limiting unit of the assistant positioning device of this invention, the user can be horizontally clamped and positioned and can concentrate his/her attention to fully give first aid to a patient without being affected by an inertia force during vehicle driving, so that the first aid effect is enhanced.一種急救輔助定位裝置,包含一個固定架、一個伸縮架,一個第一限位單元,以及一個第二限位單元。該固定架固定在固定面上。該伸縮架可上下伸縮地連接該固定架,並具有一個位於頂端的橫擋。該橫擋具有左右相反的一個第一端部與一個第二端部。該第一限位單元可滑移地設置在該橫擋的第一端部。該第二限位單元設置在該橫擋的第二端部並與該第一限位單元相配合界定出一個可限位使用者的限位空間。本發明的該第一限位單元及該第二限位單元可左右夾擠並定位使用者,使用者可不受車輛行進時的慣性力影響,並可專心全力急救病患,提高急救效果。1‧‧‧固定架11‧‧‧固定板12‧‧‧固定桿2‧‧‧伸縮架21‧‧‧下伸縮桿22‧‧‧上伸縮桿23‧‧‧伸縮樞接件24‧‧‧橫擋241‧‧‧第一端部242‧‧‧第二端部25‧‧‧護桿3‧‧‧U形架31‧‧‧樞接桿32‧‧‧連接桿4‧‧‧第一限位單元5‧‧‧第二限位單元6‧‧‧限位空間8‧‧‧防護單元81‧‧‧扣環帶82‧‧‧護套
