Objective To design an integrated emergency medical treatment system mounted on helicopter, which can meet the requirements of field treatment and evacuation in emergency disasters or local wars, the system has immobile form and mobile form. Methods With the characteristics of existing helicopter considered, the components of the system were supposed to include a universal stretchers, overall structure and embedded emergency devices and support transport accessories. Results The system could realize the destination of swift response and air-and ground first-aid, the new model of swift response can made the regulation and principle of first -aid more reasonable, and increases the survival rate significantly. Conclusion Critical diseases have become the latest killer in daily life.
