Background

The femoral artery is located in the lumen of the vessel between the femoral vein and the iliocosmetic ligament, and enclosed in a common sheath with the vein, but with a connective tissue space therebetween. The femoral artery is located in the femoral triangle, the initial section is about 3-4 cm, the outer diameter is thick and can reach 9.0mm, the part of the femoral artery is shallow and is located on the deep side of the sickle-shaped edge of the oval fossa, and superficial inguinal lymph nodes, superficial iliac veins and inguinal nerve distribution are further arranged on the surfaces of the oval fossa and the sickle-shaped edge. Near the apex of the triangular femoral artery, the medial cutaneous nerve of the thigh crosses the femoral artery from the outside to the inside, and the saphenous nerve enters the adductor duct at the outside of the artery. Behind the femoral artery, the tendon of the psoas major, the pubis muscle and the adductor longus are adjacent to each other from the lateral side to the medial side. The femoral nerve is located outside the femoral artery. The femoral vein lies inside the artery at the upper part of the femoral triangle and turns to the back of the artery at the lower part. The femoral artery is in the portion of the adductor, the front of which is covered by the anterior wall (tendinous portion) of the adductor and the sartorius muscle, the anterolateral side of which is the vastus medialis muscle, the posterior side of which is connected with the adductor longus and adductor magnus, the saphenous nerve initially occupies the lateral side of the femoral artery and then goes further forward to the medial side, and the femoral vein is in the upper portion of the adductor, located posterior to inferior and turning to the lateral side of the artery. In the state of flexion, external rotation and abduction of the hip joint and the knee joint, the line from the anterior superior spine to the midpoint of the line of the pubic symphysis and the line from the anterior inferior to the medial superior condyle of the femur, and the part of the line at the superior 2/3 is the body surface projection of the femoral artery.

The femoral artery is a large artery with violent and rapid blood flow and is usually seen in trauma. The first aid method is to stop bleeding in situ, and generally adopts finger pressure hemostasis method or tourniquet hemostasis method to stop bleeding at the proximal end of the injured artery. The action should be fast during hemostasis, so as to stop bleeding thoroughly and prevent excessive blood loss. The hemostasis method is that the femoral artery is pressed on the femur by overlapping the thumb of two hands at the position of artery jumping and the midpoint of the groin (thigh root) is deviated, so as to prevent bleeding from being sent to a hospital for operation treatment urgently.

Femoral artery hemorrhage has great harm to patients and high hemostasis difficulty, and a wearable femoral artery hemorrhage hemostasis practice model with good simulation degree, effective practice operation and help training is needed.
