Description

Emergency rescue device for medical accident scene

Technical Field

The invention relates to the field of medical equipment, in particular to an emergency rescue device for a medical accident scene.

Background

Modern rescue medicine is a science for processing and researching various critical emergencies and accidental disasters which occur in the environment outside hospitals in production and life of modern society, organizing rescue force in time, carrying out timely and effective rescue and rescue on individuals or groups on site, carrying out necessary medical treatment to save lives and relieve disabilities and pains, and transporting patients to hospitals by adopting modern transportation under medical monitoring to receive further comprehensive rescue.

In addition to the above, the subject matters of modern rescue medicine widely relate to the aspects of out-of-hospital first aid, medical and monitoring and transportation under disaster conditions, in-hospital emergency treatment, in-hospital critical care and treatment for various disasters and emergency events, poisoning rescue science, traffic accident rescue science and the like. Such as airport rescue medicine, i.e., the study of emergency situations of aircrafts occurring inside and outside airports, or emergency, treatment, nursing and the like of personnel without involving the emergency situations of aircrafts. Unlike general emergency medicine, airport rescue medicine must study rescue features related to aircraft emergencies (e.g., air accidents) and aircraft non-emergencies (e.g., fires, earthquakes). Therefore, modern rescue medicine must pay attention to disaster science problems except for medicine, for example, an airport emergency plan must be known, normal activities of an airport can be switched into an emergency state timely, orderly and efficiently, and a basic framework and contents of the airport rescue plan must be mastered particularly, which comprises mastering survival methods in distress, namely seeking survival places, protecting, seeking water and food for maintaining life and seeking survival ways; can timely and comprehensively control the injury and disease, and can stand up to firmly seek the hope of survival. Similarly, for flood control, there is a medical problem of flood control and rescue, and environmental medicine, preventive medicine and health rescue science are integrated.

When a disaster such as a traffic accident or an earthquake is rescued, a large number of surgical patients, including fracture, serious trauma, or unconscious people, occur, and the wounded people need to be treated with emergency treatment, such as fixing fractured bones, fixing cervical vertebrae, or performing emergency hemostasis. After the emergency operation is finished, the wounded person needs to be transported through the stretcher, so that the importance of the stretcher in the rescue process is self-evident, and further development of the stretcher is very necessary.
