Description

Intelligent system for aortic balloon occlusion operation training Technical Field The invention relates to the field of medical training devices, in particular to an intelligent system for training an aortic balloon occlusion. Background Resuscitating aortic balloon occlusion (REBOA) is a surgical procedure in which a balloon catheter device is typically inserted percutaneously into a blood vessel and then inflated to control bleeding. REBOA has been increasingly used over the past decade to improve hemodynamic stability, increase systolic pressure, and at the same time control life-threatening bleeding prior to and/or during definitive surgical or endovascular interventions. REBOA as a minimally invasive interventional hemostasis technique, balloon catheters are often placed into the aorta through femoral artery access, the aortic region into which the balloon needs to be placed is judged according to the bleeding part, and after the balloon is filled and blocked with blood flow, bleeding at the part below the blocking point is rapidly and efficiently controlled, so that the minimally invasive interventional hemostasis technique is suitable for emergency treatment of large bleeding patients such as non-compressible trunk and inguinal and armpit boundary part war wound bleeding, and the emergency interventional treatment technique requires a rescuer to be skillfully mastered in the technical operation key and timely and accurately implement treatment. REBOA are useful in the treatment of a variety of clinical conditions, including uncontrolled traumatic hemorrhage, post-partum hemorrhage, implanted placental lineage disease (PAS), extra-hospital cardiac arrest requiring cardiopulmonary resuscitation (CPR), and non-traumatic abdominal hemorrhage, and the like, and are commonly practiced in the non-surgical field.
