During rescue missions, time is of the essence. Therefore, the Stack-up Stretcher allows an ambulance to efficiently transfer three wounded persons at a time and provides first aid while casualties are waiting. Each stretcher has four main functions: A respirator via a pullout pipe and an oxygen-filled cushion to provide immediate oxygen supply. Flashlight handles with funnel ends to illuminate a bigger surface area during night rescue or when navigating complex terrains. Foldable metal support frames that are staggered on two sides to fold flat, or pulled open to elevate the wounded or stack the stretchers. A simplified retractable safe band with one fixed and one stretching end that can be quickly pulled out and fastened to secure the wounded.
