a stretcher for missions in the mountains during summer. because of its parametric design and the division in to three parts, it is lightweight, more flexibel and easier to use compared to currently available models. the hexanoganl structure guarantees sthrength and lightness, while titanium tubes divert the main forces. ergonomic optimized and adjustable handles provide the perfect fit while carrying the patient. all the parts can be put together on a backpack, so that one rescuer is able to carry the whole stretcher. this has the advantage that other rescuers can be faster at the patient and have more time to diagnose and care about the injuries. besides that, it is easier to carry the stretcher alone through heavy terrain. the fat bike cushions and is, if not needed, detachable.

we met with the mountain rescue schwaebisch gmuend. they showed us the equipment they use and gave us an interview.
process based on the interview we were able to analyze the process.

two first aiders get out of the ambulance to the injured person. the other doctors prepare the equipment.
tghe driver stays at the car. the other two walk with the stretcher to the place the accident happend.
the meds stabilize the injured person, put him or her onto the stretcher and get back to the ambulance.
the ambulance drives back to the hospital, or to a place, where the helicopter can land safely.
