The model is composed of a simulated arm and a peristaltic pump (electronic blood circulation device). It has the blood
circulation function generated by real hemodynamics, and has the characteristics of realistic operation and powerful
functions. Features: 1.The eight main venous blood vessel systems distributed on the arm
can perform puncture training functions such as intravenous injection,
infusion (blood), and blood drawing;
2.Demonstrate blood circulation function;
3.Intramuscular injection can be performed in the deltoid muscle;
4.The upper limb can be rotated 180 degrees, which can imitate the
rotation of a real arm and facilitate puncture practice;
5.There is an obvious feeling of failure when inserting the needle, and
there is obvious blood return when puncture is performed correctly;
6.The same puncture site of veins and skin can withstand hundreds of
repeated punctures without leakage;
7.Both veins and skin can be replaced, which is simple, convenient, economical and practical.
