After the outbreak of war or earthquake, search and rescue operations pay attention to golden time. In order to avoid the shortage of search and rescue manpower, we designed the "cloud rescue" medical aid search and rescue equipment. It has the function of infusion of nutrient solution to ensure the recovery of body function of moderate and mild casualties, and is installed with rising balloons as position markers to remind the medical staff behind to rescue. "Cloud rescue" aims to ease emergency relief, save more wounded people, and reflect humanitarian care.
