Staeoflife is an international symbol of EMS, which can be found in ambulances, ambulance helicopters, ambulance equipment and uniforms of ambulance technicians. However, a common question is, why is Staeoflife represented by a baton and a snake? Especially those who are engaged in emergency medical care will be more curious about its origin.

Staroflife is the head of the emergency treatment and rescue department of the National Highway Traffic Safety Administration, LEOR? Schwartz, designed in 1973 (American Emergency Medical Protection Act EMSACT was also promulgated in the same year). Prior to this, most signs of emergency medical care in the United States were orange forks on a white background. Because this painting is similar to the sign of the Red Cross, people are confused. Therefore, the Red Cross frequently reflects to the medical department that it hopes that the units can be distinguished by different signs. Therefore, the concept of life star has six corners, and each corner represents a function of the emergency medical care service system, including: patient examination, report, ambulance visits, and on-site disposal.
