Fracture refers to partial or complete fracture of the human flute, and most fractures are caused by strong impact. After fracture, the fracture part has pain accompanied by swelling, blood stasis and deformation, the movement of people is limited, the load can not be born, and the conditions of bleeding, shock, infection, viscera injury and the like can be seriously caused.

The plaster is mainly used for effectively fixing the bone part after fracture and preventing the fracture problem from aggravating due to the fact that the later stage is impacted by external force, so that the plaster is used on the two points, and the bone can be effectively healed better. However, the fracture reduction and plaster application can be operated only by professional medical staff in hospitals, and patients do not have hospital staff on site and professional medical facilities to fix affected limbs on site when the fractures occur. At present, the common practice is to fix the affected limb by placing two splints on two sides of the fracture and fixing the splints by binding. However, the bone of the fracture is dislocated, when the splint presses the fracture, the fracture can be displaced, great pain is caused to the patient, and particularly, when the splint is operated by people without medical experience, the injury of the fracture can be aggravated due to improper operation. Therefore, an emergency fracture fixation device is needed, which can adaptively fix the affected limb at the fracture part, avoid the bone displacement and facilitate the bone setting treatment for the doctor in the hospital.
