The function of the bleeding control thigh model is to help trainees master the standardized techniques of hemostasis and bandaging in trauma first aid. This model is designed based on a simulated human thigh and features an adjustable bleeding system that can simulate various types of arteriovenous bleeding scenarios. It enables trainees to practice tourniquet usage, compression bandaging, acupressure hemostasis, and wound treatment in a realistic environment. The skin and tissue layers of the model are clear and distinct, with a realistic feel. It can be practiced repeatedly without damage. Through the drill, trainees can become familiar with the process of bleeding judgment and handling, and exercise their ability to make quick decisions and collaborate in emergency situations. Some models are also equipped with an electronic feedback system that can display the hemostasis effect in real time, facilitating teaching assessment. The application of the bleeding control thigh model helps enhance the practical skills of emergency personnel, ensuring that bleeding can be quickly and effectively controlled in real trauma treatment and saving the lives of the injured to the greatest extent.
