● The use of polymer materials, environmental pollution, high degree of simulation

● supine position, lower limb straight extension

● Femoral artery puncture

● Arterial blood collection

● Extracorporeal circulation device: It is convenient to inject simulated blood into the model. Advanced technology is used
to simulate arterial beats. Femoral arterial pulse can be touched. The puncture needle has a clear sense of emptiness. After successful puncture, it can have realistic arterial beats and pressure perception.

● skin, blood vessels can be replaced
