The bleeding control arm model is a teaching tool used for training first aid and combat trauma care skills, capable of simulating bleeding conditions of different parts and degrees. Its operation steps usually include the following aspects:

First of all, before training, it is necessary to check whether the model function is normal, confirm that the bleeding pipeline is unobstructed, and set the amount and location of bleeding according to the teaching needs.

Secondly, trainees need to follow the emergency rescue procedures, quickly determine the nature of the bleeding, and select an appropriate hemostasis method, such as acupressure hemostasis, compression bandaging or the use of a tourniquet. When using a tourniquet, it is important to ensure that the binding position is accurate and the tightness is appropriate. Also, the application time should be recorded in a timely manner to avoid limb ischemia due to prolonged use.

Thirdly, after the bleeding is effectively controlled, a re-assessment should be conducted to confirm whether the bleeding continues, and subsequent fixation or bandaging treatments should be carried out based on the simulated scenario.

Finally, after the operation is completed, the model should be cleaned and maintained to ensure that its pipelines are unobstructed and its surface is intact, so as to extend its service life. Through repeated training of this model, trainees can master rapid and accurate hemostasis techniques in an environment close to real combat, and improve their ability to deal with sudden trauma.
