Study On Overall Technical Scheme For Added Integrated Medical First-aid Unit Of Helicopter

Ambulance helicopters have drawn much attention from the medical facilities of many countries for its advantages such as high mobility, rapid response and versatility in deferent terrain and weather conditions, which can be modified from general helicopters. As a developing country, China has no enough helicopters for modification into ambulance helicopters. Without any modification of the transportation helicopter, the added integrated medical first-aid unit of helicopter in this investigation can be applied to seriously injured patients'field first-aid and continuous treatment and monitoring during evacuation. Thus, all kinds of patients can be treated efficiently and timely, and the air evacuation of helicopters can be improved.The unit integrates some equipment for keeping vital signs for respiration, circulation, etc to realize CPR, mechanical ventilation, establishment & management of artificial airway, electrical cardioversion, defibrillation as well as continuous monitoring for ECG, blood oxygen, blood pressure and body temperature. Accordingly, life support can be implemented on seriously injured patients to enhance their life quality.Modularization technology is applied to this unit to make all modules of the unit interfaced with each other. The unit can also interface with issued equipment, e.g. general stretcher. The integrated vital signs monitoring module can display patients'physiological information on the spot and transmit related data to the experts in rear area through Internet, then tele-instruction and preparatory work can be performed. The unit can be applied to seriously injured patients'field first-aid, keeping vital signs for CPR, ECG, blood pressure, body temperature, respiration and saturation oxygen, as well as emergency treatment of combined injury and multiple injuries.
