Also known as emergency medicine or emergency medicine, emergency refers to the actions taken to quickly examine and diagnose patients; first aid is the emergency medical service provided to prevent the death and subsequent disability of patients in critical conditions. Both are the core of emergency medicine. The emergency medical service system is an institution responsible for implementing effective on-site first aid, reasonable triage, organized transfer of patients, and close contact with base medicine. Emergency medicine can be divided into two categories: trauma and non-trauma.

[0003] After searching, a Chinese patent with a patent publication number of CN219183954U discloses a tourniquet for bleeding in limb trauma, which belongs to the technical field of tourniquets.
